LOL, it's always the way

Bridgestone SO2 Pole Positions, probebly the best tyre on a Standard 16" wheels, masses of grip but they wear out quickly if you spin them a lot.

Please share (not for me but for others out there)

I had Porterfield Pads (R4-S) on my J-spec setup, and they wre excellent for the road and also very good for the first trackday I did at Bentwaters (not as punishing as the later trackdays there I gather). I also run them on my Integra Type R and they are amazing, same compound on 285mm disks (standard) and only 2/3 of the weight of the Supra (if that). I'm going to get them fitted to the misses car also (Paul Whiffin and myself jhave sorted out some that will fit (same as the FTO GR Paul)), as soon as the current ones get low.

It's pretty much the same as the one you sent me only with more slip (back upto 5%, 10%, 15%) as I found I was using it on the highest slip setting in the dry. It's hard to get a balance between the TC and the LSD, too much TC and you can't control the back end right, I suppose I use it differently on the FWD than on a RWD in that I don't really need much TC to keep it under control.

I don't KNOW, but a little birdie has told me that it is the stock ECU with a daughter board add on chip. Not that that is neccessarily a BAD thing, but nor is it a true stand alone ECU. Time will tell, I am very curious myself. That's how the zdyne is done for Hondas are done I think, The Hondata is very similar only needs an eprom blower and rom emulator to blow chip for it. Pretty sure from the posts on supraforum that the AEM was true standalone, but could be wrong.

Yes, I have Grahams App. I have tried wiht both Invert Clutch switch "on" and "off" I either get rev limit at all times (pin grounded or not) or get no limit (pin grounded or not) depending on the setting

How good is the GEMS, if that is what the board is based on then it should be as good as that (with the advantage of plugging straight into the loom)

Ahh, venting from the fuel tank, knew it was some sort of venting

OK had another go at getting it working, the RLTC Manual says you fix the clutch switch to pin 20 then you can set it to bring in the limiter when grounded (or you can invert this), anyway I have tried it every which way and I either get a constant rev limit, or no rev limit at all with grounding the wire making no difference in either case. I even tried all the other spare connections incase the manual was wrong. Anyone else tried to get it working!!?!!?? I was hoping to get it sorted before Santa Pod on the 7th

I think it's an oil catcher, when air from the engine is vented it goes through a charcoal filter or similar to remove the oil vapour (for eco reasons), that may be it.

Didn't realise you had a spare set. This is the info I have http://www.derestricted.net/itr/mods/Injectors.htm I will look into it a bit more before arranging to borrow them. (Edited by HardHead42 at 9:26 am on Mar. 24, 2002)

How about some carbon brake disks and appropriate pads?

Last post as it's gone a bit off topic with the MkIV injectors being side feed. At the bottom of this page theirs a cam kit including a set of "440cc Toyota injectors (new)"! Are MkIII TT Supra Injectors 440cc? http://godspeed.hack.net/toda.htm here's a pic of RC 310cc injectors look familar to anyone? http://www.mkivsupras.co.uk/ http://www.derestricted.net/itr/mods/RCE1.jpg

Some info on Endless pad compounds, OK if you read Japanese I suppose Not sure of application. Other compounds on the site also. http://godspeed.hack.net/endless.htm http://godspeed.hack.net/images/EndlessNAS.JPG http://godspeed.hack.net/images/EndlessMA11.JPG

Baaa, they're top feed. Looks like I'll be getting the RC ones. (Edited by HardHead42 at 7:22 am on Mar. 23, 2002)

Thos mods will make a big difference on a Supra and should see you boosting to about 1.0-1.2kg/cm2 (close to bar in scale, standard is about 0.8kg/cm2). If your's doesn't (some cars seem to resist boosting more with even both cats removed, mine did), then add a boost controller or bleed tee and get it boosting to between 1.0-1.2kg/cm2.

Just wondering do you have to order the 540cc kit with the ECU, if so it may mean that the ECU you get when you buy the ECUC+540cc kit, is mapped for the 540cc injectors. I can't personally see how the ECU will "adjust" to the new injectors at WOT without some sort of intervention, as it will only be using the O2 output (and therefore have an idea of how rich or lean the mixture is) when in closed loop (is that the right term always get confused with closed and open), when idling and cruising/like acceleration.

Thanks I'll look into these other aspects of the injectors, side or top feed, and resistance (is that something I can measure because I've looked around for it before but not been able to find it) If I have to do any fabrication then it's not worth it because I'd have to pay someone to do it, and RC do lots of options for the Teg R and are not all the expensive and do a 310cc and 370cc which are more liekly to be the size I am looking for.

Yeah that's the way they are set up as standard. In fact I believe the standard set-up runs a bit rich and the APEXi seems to be perfect mixture (runs at 0.82 on the O2 sensor voltage, which I believe is supposed to be optimum for power according to a few sites I have seen). I may plug the original ECU back in and see what that runs at. I have even had 100% duty when caning it when it wasn't totally warmed up (there's fuel enrichment based on water temp). I know I'm bad but the guy in the Audi TT needed teaching a lesson

Sorry, I should clarify I don't have an APEXi S-AFC, V-AFC or AVC-R piggy back type unit. I have an APEXi PowerFC replacement ECU the duty cycle it is reporting is what it is using to run the injectors, so I'm hoping it's pretty accurate. The Integra Type R is well know for using a lot of duty on their injectors, so the high figures aren't a supprise to me. Are you going to Santa Pod on 7th May? I wouldn't mind having a look at one of your 440cc s to see if they will physically fit.

OK get up off the floor I'm talking about swapping my 240cc injectors on my Integra to 440cc JDM Supra ones. This is the info I have, 1992-00 Integra type R - Saturated - 240cc 1993-up Supra non Turbo - Saturated - 315cc 1993-up UK Supra Twin Turbo - Peak and hold - 550cc 1993-up JDM Supra Twin Turbo - ??? - 550cc How much more info do I need to know if they will work? Obviously I'm not sure if they actually fit, but I'm sure someone who has done an upgrade to 550cc can let me borrow for checking the dimensions. If it all works there may be a market out there for all those old 440cc injectors sitting in boxes after upgrades. Some will be asking why, well I'm hoping to get some pretty wild cams some time this summer and the current injectors already hit 95%-100% duty on virtually standard setup (according to the APEXi ECU readout) and I don't want to raise the fuel rail pressure when I already have a programmable ECU installed. If any fabrication needs doing it's not worth it as you can get a set of 4 RC injectors in 310,370 or 440cc sizes for about 250 + delivery Hoping someone like CW will be able to shed some light.

Pretty sure Pete Betts already makes one (or it is in development) may be worth asking him.

Yes that's the same probe as we have over here, same underlying chassis as the MX6 I believe. Like Chris says, putting a good FWD engine into it will be a lot easier, cheap and you'll get a nicer convertion. The Supra engine and gearbox are so long you'll either end up with a car where the engine over hangs the front wheels and will handle like poo or you'll be driving from the back seat because that's where the gear lever is Even putting another manufacturers FWD engine/gearbox in the front will involve a lot of work, nowhere as simple as putting an engine from the same manu in (like the Honda swaps you see alot in the US, and Vauxhall ones in the UK). Worse than that the engine will basically be Mazda based and I can't think of a good FWD Mazda to swap from either!!!
