Guest scottaii Posted April 15, 2009 Share Posted April 15, 2009 Hello there!, Been looking around the forums for a bit getting to know a bit of the lingo (which i still don't know any... apart from BPU haha). Been looking at Supras for a good couple of years thinking "wow id love one of them" but only recently been looking into the details of them, as i can now afford one and turning 21 soon (so insurance goes wayyy down). Couple of questions: 1) I got confused on the spec of the Jap imports and the UK spec. From what i understand the UK spec where build with higher performance with a better BHP. But, is this the case because the Jap versions have a limiter on them or are the engines actually worse? ( I.E Are jap imports as good as UK spec?) 2) Will i find any Manual | 6sp | Aerotop | TT | RHD for sale... atall? I have seen a good couple of Auto's, Very nice actually, but having never driven an auto whats it like? 3) Know anywhere i could get BPU fitted in England? Cheers guys!

SimonT Posted April 15, 2009 Share Posted April 15, 2009 Welcome mate! Have a look here for general info: http://www.mkivsupra.net/vbb/forumdisplay.php?f=69 And as for driving an auto, personally i think the Supra has one of the best auto boxes around so you cant go wrong and i dont think you can get a Manual 6spd Uk Aerotop TT as im not sure they were even made but im sure some other guys on here could let you know!!

Al Massey Posted April 15, 2009 Share Posted April 15, 2009 They never made any manual aerotops in this country so if you see one it is because someone has done a conversion. And there are a few traders on here that will do BPU for you Quote Link to comment Share on other sites More sharing options...
AndyT Posted April 15, 2009 Share Posted April 15, 2009 Welcome. The Jap spec cars differ slightly to UK cars. About 30 BHP difference. Smaller injectors and ceramic turbos (Have to run slightly lower boost) being the main difference. The engines are the same. UK cars are much rarer and the nor. here is J spec. Most of the traders here can kit you out to BPU level. Whifbitz in London, AFR, Toyota GT etc. If you find someone closer post here to see if they're any good before letting them loose on your pride and joy.

The stated figures of 280hp for Jspec was just a gentlemens agreement between manufactures. Quote Link to comment Share on other sites More sharing options...
Guest scottaii Posted April 15, 2009 Share Posted April 15, 2009 Cheers for all the quick feedback! i didn't think there were any manual Aero's in the UK but i though id ask the people in the know That's nice to hear that the Auto box is a good one, Although there's something about manual... you feel more in control.. how can i put it? Are there many people who do Auto - Manual conversions? Ahh good to hear about the Local meets, how many people turn up to these sort of things? (im actually in Swansea butt ) Standard j spec making 332Hp.. thats nice! What sort of increase in Bhp have people noticed from having a BPU?

Gaz6002 Posted April 15, 2009 Share Posted April 15, 2009 You'll see around 380bhp at the fly for 1.2 bar BPU. Quote Link to comment Share on other sites More sharing options...
Guigsy Posted April 15, 2009 Share Posted April 15, 2009 BPU will give you anywhere between 370 to 420bhp depending how much money you throw at it, if it was uk or jap initialy and what bar you run, oh and where you have it dynoed Quote Link to comment Share on other sites More sharing options...

Guest scottaii Posted April 16, 2009 Share Posted April 16, 2009 Just read the supra info made by AeroDave and its brilliant, nice to have a personal slant on things (such as him liking the auto e.c.t). Very good point of his also is that if you want a manual gearbox for good corners e.c.t why would you want a aerotop model that will twist slightly because of the design. so now i have to decide if i want the Aerotop (Auto) or a hardtop (manual).... oh the choices [ i cant believe my dream can now become reality! ] Gaz, How much has that cost you (inc labour) for your setup? How reliable is it? (are you having to constantly tune it?) Would you say travel Europe or a long distance in it? Quote Link to comment Share on other sites More sharing options...
Holden1989 Posted April 16, 2009 Share Posted April 16, 2009 i didn't think there were any manual Aero's in the UK but i though id ask the people in the know I can think of two in the UK, one being a single turbo and one being a hybrid tt cant think of any more Good luck in your search Quote Link to comment Share on other sites More sharing options...
tDR Posted April 16, 2009 Share Posted April 16, 2009 The J specs make the same power standard as the UK and are cheaper to get c390bhp out of. They also have faster spooling larger turbos that dont need the same excessive boost level of the UK's to get them moving Quote Link to comment Share on other sites More sharing options...

Either you have a boost controller or it was a very generous RR Fuel pump on J Spec is man enough for BPU but to be honest I'd always swap it on J or UK for safety given the age of the cars.

Guest scottaii Posted April 17, 2009 Share Posted April 17, 2009 Theres one for sale here (nice red one) 5ps manual tt aerotop, looks very nice actually. so much info on this site its brilliant! How far would you trust a BPU TT j-Spec to travel? could you do a (for example) European tour? (its an idea me and my friend have) P.S When you say "Spool faster" does that mean start spinning faster or.... Quote Link to comment Share on other sites More sharing options...

That £20 I slipped to Matt just before the open day paid off in the end Stock all the way dude, that exhaust probably cost you about 32bhp I'd estimate How far would you trust a BPU TT j-Spec to travel? could you do a (for example) European tour? (its an idea me and my friend have) P.S When you say "Spool faster" does that mean start spinning faster or.... Many Supras on here have been to the moon and back. My UK is on 113,000 miles and never misses a beat (except when it's cold, but that's cos my battery needs replacing ). The UK turbos have steel internals, the j-specs have lighter ceramic internals. The UK turbos therefore require more energy to get spinning to provide boost. Overall, it means the j-spec turbos can, in theory, provide boost at a lower RPM level than the UKs. Given that owners of both UK and j-specs on here agree that the first turbo provides boost from about 2k RPM, and the second turbo cuts in at about 4k RPM, I'd say the difference in engine speed for the two variants of Supra is largely negligible. Oh, and to throw my 2p into the can of worms debate....when UK turbos let go, they don't tend to go catastrophically Quote Link to comment Share on other sites More sharing options...

Would you say travel Europe or a long distance in it? I honestly would hate to add it up... let's say well over £15k on performance mods. It's reliable as long as you look after the car and keep it serviced regularly. I've driven through Europe several times and I have had some problems, but I'm confident my car will be perfectly reliable next time I hit the Nurburgring. If done correctly, a single turbo Supra should be just as reliable as a BPU car. After all, in theory there is less to go wrong Quote Link to comment Share on other sites More sharing options...

Lose the rear wing, front bumper and shopping list and it would look ok. Quote Link to comment Share on other sites More sharing options...
