ad500 Posted February 1, 2003 Share Posted February 1, 2003 Hi all, im new to this forum and already seem to be asking for help. I bought a UK Spec TT 6 speed 6 months ago. When i got the car it had a whole load of reciepts from TDI in Essex and its had the following work already done. I understand alot of it but as the work was done by someone else i sometimes wonder whether i do understand it all or not. It sounds really ignorant but im not sure where to go next. The owner said that all the work was done in preperation of going single turbo (hence the built engine) but with the work thats already been done im a bit clueless as what to do next. All the following have shown up on TDI receipts HKS parts: S type intercooler, titanium pistons, 256/264 cams, vein pressure controller, boost controller, turbo timers, metal head gasket, twin power ignition, ssbov, hybrid turbos, iridium plugs, super dragger exhaust, downpipe, powerflow induction kit, racelogic traction. Things im clueless about: its also had engine work: recut valve seats, refaced valves, rod bearings, main bearings, t washers, bore/hone crank, lap crank journals Plus things im guessing about: FCD normal (fuel cut defenser i guess) £85 on receipt so is it a good one or not? Recirculating valve- what is this? EVC 4 univ £355 on recieipt - what is this? JZA80 SQV £220 on receipt - what is this? Cam Pulley 1/2 JZGTE £85.50 any good or not, i guess these arnt the same as cam gears. There are no cats in place. All these things are on receipts, ive spoken to TDI who verified the work. I wouldn't mind going single turbo this year but the receipts make no reference to twin in tank feul pumps, larger injectors or rails. Or would i not need these? Help ive had the car six months and all ive done is put EBC pads on and aluminium brake lines. Link to comment Share on other sites More sharing options...

THOR Racing Posted February 1, 2003 Share Posted February 1, 2003 Welcome to the list.... FCD normal (fuel cut defenser i guess) £85 on receipt so is it a good one or not? HKS FCD. Scales the MAP pressure signal and clamps below fuel cut threshold. Allows you to boost your turbos above the Toyota ECU settings. I will not comment on it being good or bad as I sell an alternative and this would be unfair/biased. Recirculating valve- what is this? The valve that sits between the turbos and recirculates the pressurised air back to the air intake during throttle off. To prevent build up of back pressure on the turbo blades. This sounds like a replacement Toyota spec one. That's fine as many at this age don't work anyway. You'd be suprsied how many people drive around with non-working recirculation valves (luckily they fail safe) EVC 4 univ £355 on recieipt - what is this? Electroinic Valve controller (not quite sure on exact name) BUT it's an electronic boost controller. Allows you to control the amount of boost your turbos generate and hence how much power the car generates. JZA80 SQV £220 on receipt - what is this? Sounds like the Sequential BOV (as suggested already) Works in the same way as the recirculation valve but dumps it's air to atmosphere and not back to the air intake. A bit of an overkill but doesn't hurt, plus they sound great. I have one and removed my stock recirculation valve. The VPC (Vein Pressure Converter) simulates the MAF (Mass Air Flow) meter which you used to have in the air intake, causing a small restriction in the intake air flow. This now means that the BOV to atmosphere is O.K. There is an argument that dumping pressurised air to atmos' will give faulty air/fuel calculations when a MAF is fitted. I'm assuming the VPC takes care of this. Cam Pulley 1/2 JZGTE £85.50 any good or not, i guess these arnt the same as cam gears. Don't know on this. CAMs are not my thing. Anyway, Nathan (representing TDI) will be along at somepoint to put you straight. Regards Pete Link to comment Share on other sites More sharing options...
qaisar Posted February 1, 2003 Share Posted February 1, 2003 sounds like sn impressive list. u might want to contact nathan to get a full low down as he id from tdi and may have seen ur car Link to comment Share on other sites More sharing options...
ad500 Posted February 1, 2003 Author Share Posted February 1, 2003 thanks for the replies, that cleared a few things up. Im having problems finding anyone to take the car to who knows about Supra's in general. I wondered if anyone could recommend anywhere around the Oxford/ Bicester/ Banbury/ Northampton/ Aylesbury areas. Ive tried Toyota Inchcape in Kidlington, Toyota in Fenny Stratford, Engine Room in Bicester, Performance cars in Buckingham. Engine Room was fine for servicing and changing the cambelt, but have got a bit stuck recently diagnosing a rear wheel sound (not bearing or drive shaft). Toyota main dealers were useless, they keep recommending changing parts until we came across the right one. Id love to find someone in this area who knows the cars inside and out, i just seem to take endless days off work sitting aroung garages listening to peaople say "not seen one of these FTO's for ages". If your out there let me know, id love to give an expert my money. Link to comment Share on other sites More sharing options...
Branners Posted February 1, 2003 Share Posted February 1, 2003 Leon at JPS Motorsport is located in Bletchley Milton Keynes, 01908 367100. Is yours the car that has (or had) the Aston Martin badge on the front? JB Link to comment Share on other sites More sharing options...
Darren Posted February 1, 2003 Share Posted February 1, 2003 Hi AD550, Nice spec car. Did you get any Dyno (Rolling Road) results with the car giving current BHP details? Just interested in what a well modded Supra puts out on Hybrids. Cheers, Darren Link to comment Share on other sites More sharing options...
Bobbeh Posted February 1, 2003 Share Posted February 1, 2003 I think this car is the one that guy from Peterborough was trying to sell here a few months back.. with Aston Martin badges on (If so, PLEASE TAKE THEM OFF NOW! ) and featured in a magazine? He claimed about 500bhp? Go down to G-Force @ Aylesbury to get it dyno'd for us please Welcome to the site etc Nice car! Link to comment Share on other sites More sharing options...
ad500 Posted February 1, 2003 Author Share Posted February 1, 2003 Yes it is the same car, and yes i took the Aston Martin badges off. I couldn't take them off for 2 weeks until the HKS badges arrived, which were about the only ones that would cover the holes left by the Aston badges. I even had one guy follow me to my house and on to the driveway to ask what Aston it was. That was embarrasing trying to explain it wasn't me that put the badges on, he kinda shrugged and said "whatever mate" and then proceeded to explain to the guy on his mobile that it wasn't an Aston that went past but some guy with a supra who thinks he has an Aston". I picked the car up for £15000 in the end I think Brian originally wanted £18000 but needed a quick sale. The cars been no real problem since, although in 6 months ive had to buy 4 new tyres (rear camber was badly negative), rear suspension bars, upside down rear bump stop, major service inc cambelt etc. I still think apart from that it was a good buy considering all the work that has been done is documented with receipts. it would have taken me ages to do all that and while i was looking most UK spec cars with maybe only 1 or 2 mods wern't far off the price anyway. I rang G Force last week to check about dynoing the car. He told me that there were a load of supras down there a few weeks back. Brian said it was 500bhp to me, ill see what comes out when i take it. Link to comment Share on other sites More sharing options...
Bobbeh Posted February 1, 2003 Share Posted February 1, 2003 Cool I saw the car for sale when I was looking I think.. but I could never afford the insurance with all those mods so I had to find a stock car. Looked like a nice car.. funny and sad about that guy who followed you I could never drive around pretending to be something else.. and saying to people.. "yeah its an Aston :)", I havent got the audacity! Wish I had I was down at G-Force with the Supras.. hence my figures in my sig.. also went a couple of weeks ago with a m8. Really good place, friendy guys and the equipment used is top notch. They have a nice collection of cars to look at too Link to comment Share on other sites More sharing options...
Alex Posted February 1, 2003 Share Posted February 1, 2003 Titanium Pistons! ???? Don't believe that. Nathan, could you please confirm or deny these? Thought it was just fitted with HKS pistons, which arn't Ti AFAIK. Link to comment Share on other sites More sharing options...

ad500 Posted February 1, 2003 Author Share Posted February 1, 2003 Titanium pistons?? You guys are probably right about the pistons. Im basically quoting everyting that was written on the specs list that Brian gave me. Ive looked on the receipt from TDI and it just says HKS forged piston set. So when Brian said they were titanium i just had to go along with it. I didn't have all that much time to research the mods at the time and funnily enough no-one has ever picked up on the Titanium think being wrong. At least i know now. Bobbeh Insurance was pretty cheap at £917 fully comp, all mods listed with tesco's. Link to comment Share on other sites More sharing options...
Bobbeh Posted February 1, 2003 Share Posted February 1, 2003 WTF! £900!! Dayum, how old are you and whats your NCD etc? Maybe they know its not putting out 500bhp somehow! Link to comment Share on other sites More sharing options...
Nathan Posted February 1, 2003 Share Posted February 1, 2003 Originally posted by ad500 So when Brian said they were titanium i just had to go along with it. Welcome to the BBS! Ahh...the fabled Supra with red tints, camera on the roof, Veilside kit and of course those talked about Aston Martin badges... I remember Brian explaining why he had them fitted- it was because someone once commented that they thought the car looked like an Aston (well, the DB7 side profile is pretty close) so off he went and put Aston badges on it! Each to their own I guess. As for the pistons, indeedy, nice bloke as Brian was, it's fair to say he did get a little mixed up now and then.... Suffice to say the invoice says 'forged pistons' which I'll go along with as being alloy, not titanium. I'm fairly confident that it won't reach 500bhp either; I certainly didn't quote that and I'm pretty sure Mark didn't either. Around 440 I reckon if it's running as it should. Be interesting to see what it makes. If you go to G-Force please let the BBS know. The car is itching for a big single or twin but Brian couldn't be doing with the lag. Various options were talked about at the time, including 3.4 but Brian never got around to it. You will indeed need the HKS fuel rail, regulator, 1000 injectors, fuel dampener bypass and maybe a dual pump setup if you want to go big single/twin. You will also need another VPC ROM (chip). I don't remember speaking to you about this purchase- maybe you spoke to Mark. Hope you enjoy the car! Best regards, Nathan TDI PLC Link to comment Share on other sites More sharing options...
ad500 Posted February 2, 2003 Author Share Posted February 2, 2003 Hi Nathan. Brian was a nice guy but he wasn't able to give me much info on the technical side of the car because i don't think that he fully understood it himself. I bought the car on the strength that all the receipts were there, the work was done less than a year ago and it was done buy a specialising company. The car has been like buying anything second hand, ive had to live with the previous owners adjusments. I am toying with the idea of removing the tints, camera and wooden dash (stick on). The veilside kit i like. If you could put a ball park figure on the cost of going to around 500-600bhp reliably, whether single or twins, how much would that be approx. Also does anyone know if the split rim alloys can be blasted and re-chromed, Brian admitted to being an enthusiastic driver and one or two of the alloys bear testimony to that. One or two people have said never split the rim. By the way Nathan, the engine has been completely reliable (touching wood right now). Link to comment Share on other sites More sharing options...
Alex Posted February 2, 2003 Share Posted February 2, 2003 Do a search for "Pristene" or spellings similar to that...they do wheel refurbs, not cheap but by all accounts they do a superb job. Glad to see I wasn't going mad on the Ti piston thing! Single Turbo for 5-600RWHP would be (if we talk about HKS only) a T04R in my opinion. A pair of 2835's would only need to run moderate boost to get that HP figure (one 2835R is good for 400-450bhp on its own ). Unfortunately HKS didn't, when I last checked, do a smaller 2530 or similar kit for the 2JZ-GTE motor. Having said that if you got a custom manifold (which was the main reason 2530's don't fit the 2JZ) I would opt for a pair of them. I wonder if any tuner has a custom manifold for a pair of GT25's...... The 2530's as a pair will run to 600hp. These are probably the best sized turbo's you could use on the Supra (which is to remain a street weapon ), which is why its frustrating that HKS don't make a kit for them.

ad500 Posted February 2, 2003 Author Share Posted February 2, 2003 I spoke to Pristine in Milton Keynes about a month ago. They do a wheel exchange system where yo give them yours plus cash and they give you a refurbed set. They didn't have anything in at the time that was 18". They said that they could have a look to see if they could split them but wanted the wheels for a week. As i drive it to work i really needed a spare set and they didn't have any, ill have to wait for a bit of holiday to come up. Bobbeh Ive just turned 31 and the insurance people know about all the mods. They sent the details off to the underwriters who came back with the figures. I even got £15 off to put the g/f on. It took about 4 tries to get the documents to come back with the correct mods on, everytime they missed something off which meant more phonecalls. Im dreading having to claim on the policy because Tesco can be a bit slow. 5 years no claims by the way, but the real killer is £700 excess. Cheers for the turbo advice Alex, HKS have got the T04R priced at a delightful £4350 ex vat. Anything cheaper worth going for or am i just being a skinflint!!!

Alex Posted February 2, 2003 Share Posted February 2, 2003 Monkeymark has a thread going about turbo kits on the General or chit chat section. HKS are expensive, but they do work.... SP57/60 should be enough for your needs....if it fits a right hand drive car Link to comment Share on other sites More sharing options...
Syed Shah Posted February 2, 2003 Share Posted February 2, 2003 Why were forged pistons fitted? The stock ones are already forged and as good as anything else available. Has it got forged rods? These would be a much better bet. It's a nice car, glad it hasn't got the Aston badges anymore Link to comment Share on other sites More sharing options...

It's a nice car, glad it hasn't got the Aston badges anymore Im not sure why some of the work was done. I agree the stock internals can cope with much higher outputs than this car makes. I guess id have to see if nathan knows anything as to why Brian wanted the work done. As for con rods i don't know if any were put on, Brian lost a few receipts which is what prompted me to start this post. I didn't want to start paying for stuff that was already done.

It's a nice car, glad it hasn't got the Aston badges anymore The stock MKIV TT pistons are cast and boat anchorish heavy. A decent forged piston will take a lot of stress off the crank and rods, as well as being themally more stable. Cosworth do some beautiful pistons for the 2JZ-GTE, via JUN.

A decent forged piston will take a lot of stress off the crank and rods, as well as being themally more stable. Cosworth do some beautiful pistons for the 2JZ-GTE, via JUN. Agreed. There are pistons and there are pistons. The stock items are certainly NOT as good as anything else available. I believe that the pistons are the only bottom-end mod the car had, mainly because the bores were fairly worn and also because Brian had bigger plans for the car. FWIW, a mk4 with forged pistons is a good find: it gives you a lot more scope for (reliable) power hikes. Regarding turbos, yes I would probably opt for an HKS TO4 if I wanted 500~600bhp. As I've mentioned before, a pair of 2530's would be REALLY nice but HKS don't offer a kit. Major shame We fitted 2510's to a stock-manifolded Supra back in the early days when hybrids were unknown. Worked well, especially as the sequential was retained, but the cost would outweigh the power gain when hybrids can get near it these days. Would love to do a custom manifold running 2530's and sequential but the cost would be horrendous. If you're baulking at the cost of a TO4R kit then don't even think about it Funnily enough, it was Brian who was the closest customer we've ever had to going for it. He was NEARLY there....
