The NEW t-iv (black cans stuff) is compatible with all other fluids, dex II, III, etc. but why stick T-Iv when when dex II will do the job. keep the T-Iv for the gearbox.

Good link. I got a transmission specialist to do mine (total flush).. its not that expensive. It was £60 for flush, service, and gasket. They have an excellent reputation. The fluid cost me £125 from toyota though, T-IV (i was left with one can spare at the end as they only needed 12 litres to flush it. I can certainly recommend these guys... they really know their auto boxes . They've been going for years and are one of the best. VM Transmission Products (01543 270555). Cannock in Staffordshire.

odd..unless you're trying to send to my old hotmail account, as thats now deleted. try [email protected] that should work ok. cheers adi

yep.. i'd be interested in seeing the pics... can you post a link?

Its the gearbox ECU telling you theres a fault..if you know how to get the codes you can see what it means. try http://www.mkiv.com .

yes they do fit straight in.. and they do a nice job of sustaining the fuel at higher boost...Would you be willing to let some go in a couple of weeks or so?

Ian, i may well be interested in taking a set of your 440's off you.. the 1JZ injectors are side feed high impedance.. let me double check a few things and i'll get in touch with you soon. cheers adi

okay..cheers for all the info ..much appreciated. adi

wahey..cheers Ian, nicely explained..got it now. so in the above scenario...what would happen if i fitted a 2 bar MAP sensor (same voltage ratio obviously). I could then effectively map the fuel without the guesswork of revs and throttle?

The stock injectors are side feed..although i think low resistance..i'll have to check. But if you use a fuel controller based on revs and throttle, then how does it alter fuel? by altering the MAP input to the ECU? But this maxes out at 5V and 1.1bar so how on earth does the AFC tell it to *add* more fuel over pressure of 1bar? I can imagine it tells it lower down the rev range that more pressur is being applied than it actually is, but when we start reaching max pressures and voltages i cant see how it works.. does anyone have an idiots guide to the S_AFC and all things MAP?

Basicaly, i was told by an ex MOT tester mate of mine...if they dont have the car on record, and as long as the emissions are within limits...you're fine...regardless of whether it has a cat or not. adi

I think this needs a lot more thought before i do anything.. For now i'll fit an FCD and just slightly raise the boost cut to stop it happening, then get it checked out to make sure im in no danger of leaning out. I think that even with the altered signal to the ECU i should still be okay regarding fuel, as the 1JZ runs rich anyway (mine is running way rich at the minute, so much so i can smell it). There is someone else on the soar*r list (edited for diplomatic reasons) that has just fitted the same turbos..so i think i'll wait and see what he does. It looks for now like the way to go eventually will be a 2 bar map sensor and something like the power FC, the problem being there is that the power FC doesnt like autos (particularly the 1JZ) and therefore i cant use it. arse. This is all extremely frustrating..i've got an engine that can provide enough fuelling as stock for 400+bhp, two turbos that can take pressures of 28 psi and i cant even push them enough to raise a tickle ! This has been a bit of an eye opener...what is boost cut on the mkiv (17 psi?). How do you lot running 20 psi get around it ? adi PS Adam, i'm ashamed to admit the 1JZ injectors are a measly 370cc, even less than the 7M, but they do a damn fine job!! Its also extremely difficult to fit larger sizes because of the design.

Apparently Pete reckons you can fit his FCD with an S-AFC , as long as the FCD is closest to the ECU in the line. Regarding the S-AFC though..Obviously i need to richen the mixture at the same time as fooling the ECU into thinking i'm still running under 1bar. SO...... leaving the FCD aside for a minute...If i fit a 2bar MAP sensor, fit an S-AFC.... no ..its no good..its a complete head f**k. Im totally confused.. I've got to do something sharpish though..i hit boost cut three times today and it cant be doing my engine any good. adi

yep..spoke to pete last week..i was just wondering what the findings were of people who'd been in a similar situation (albeit on a 2JZ). I'm prob ordering an FCD off pete next week.

Hi all..wonder if anyone can help. Heres the situation.. 1JZ engine (virtually identical to 2JZ for the purposes of this thread). Recently fitted hybrids..now hitting boost cut on stock boost. I want to get rid of boost cut and run 18 psi if poss (stock turbo 1JZ boost is 10.5 psi, boost cut 1bar, standard MAP maxes at 1.1 bar i think, same as yours). How do i do it? 1) FCD- Fitting an FCD to increase boost cut will make the engine lean??? Im assuming this as the MAP signal is altered to fool the ECU into thinking pressure is still below 1bar. Hence no extra fuel will be added to compensate at higher pressures...obviously leaning out the engine. If i ran 16-18 psi with an FCD i'd be getting lean ..is that right? 2) S-AFC an S-AFC also fools the ECU into thinking different amounts of air is entering the engine...and obviously the ECU compensates in the way of fuel...but can an SAFC richen the mixture whilst running higher boost on stock injectors? Can it also effectively remove boost cut? 3) What should i do??? I'm confused Points to note. The stock 1JZ fuel system supplies enough fuel for 400 bhp. I hope i've explained what i mean..if you need nay more info just tell me what. Cheers adi

hmm i'd go for the full drain if filling with type IV (if you've got £125 spare for the fluid). Although the NEW type IV (make sure you get the new stuff part number 08886-81015) is compatible with all fluids, they do say you will only feel the difference when at least 75% of the fluid is the new stuff. Doing a sump change will do next to nothing. If your car is now a few years old it'd be adviseable to do a complete change anyway, as it prob hasnt been done for a while. I paid £80 i think for a very reputable gearbox specialist to drop the sump, drain everything inc toque converter, new gasket and a general service. All in all i think it was £200 well spent and well worth it for peace of mind. The gearbox is just as complicated as the engine, and should be treated as such. adi

If you check http://www.turbotechnics.com they give a run down of symptoms to look out for with a blown oil seal. I've just had both of mine rebuilt (CT12A, slightly different fromthe CT12B) after oil seal going..but the symptoms were different as mine hadn't fully let go (i had smoke on kickdown, and smoke at traffic lights, but it didnt smoke when i revved it at standstill). As a rough guide my hybrids from Turb Tech were £1300+vat for both, with an owners club discount. adi

Arse...i like the look (and the price) of the Blitz SBC, but also need an air/fuel controller...and they dont make one to match the design of the SBC !! That sucks.... guess it'll have to be the apexi units then..although the power ID and SBC does sound tempting..

My early symptoms of turbo seal were as follows for comparison. :Couple of seconds after a blip at stand still smoke would come out, hang around in a wispy kind of way (only after a long run). :Smoke when sitting at traffic lights, particularly after a hard run. Would continue until i drove off again, or carry on until the engine is turned off. I never used to see any smoke when driving, only at speed on an O/D kickdown. adi

I think universal turbos fit ceramic bearings rather than ceramic turbines. adi

additional... tin the wire *and* the track. adi

Rather than solder onto the track..cant you tracethe track back and solder directly onto the component leg. Tracks can lift off the board very easily, especially if your soldering skills aren't good.

i used to like the spoilerless mkiv's, until i saw one. There's one a few miles away from me...gone right off them now. I think the spoilerless ones look better with a LOT of lowering. adi

Has anyone any experience of the old style s-AFC (the one with the manula twirly pop out buttons)? I may have to fit an air/fuel controller soon and seing as im now skint after the turbo episode i cant warrant paying £400 for the new SAFC. Do they do the job well enough? any comments? cheers adi

I think it was down to individual(s) rather than the clubs themselves. I use the LSOC regularly for engine info and most of them seem very helpful and friendly. Things did get a bit out of hand though.. I sat in a soarer the other day...unvelievable build quality and luxury. well nice...not a supra though. adi
