Okay about a month ago I bought a 93 r32 gtst type m..

Mods are:

T04e high mount

FMIC

Yellow jacket coil packs

550cc injectors

Walboro in tank fuel pump

Tial waste gate w/screamer

HKS bov (will be putting stock BOV plumbed back shortly)

Mines ECU

Adjustable coilovers

Just want an estimate of kw from the wheels ill be getting? Only a rough estimate obviously. AFTER A TUNE!

OK, so the power will be limited by one of three things.

1) The turbo.

2) The injectors.

3) The ECU.

Start with the easy one. Your Mines ECU was a waste of money. It can't be tuned (if the EEPROM has been glued in). If the chip isn't glued in, at least you can convert it to Nistune. But then you can do that with a standard ECU anyway. (And, yes, I assume the Mines ECU was already in there when you bought it and therefore it's not your doing, but nevertheless). Worse, the Mines ECU is not well suited to running in Australia. Intended to run on Japanese 100 octane and tend to be fairly over-advanced. Can ping an engine to death pretty quickly in the wrong circumstances.

The injectors will do no more than 300rwkW, give or take a bit. But that it plenty, and probably a lot more than you'll get out of a TO4e on an RB20 anyway.

I suggest you scan through the RB20 dyno thread and see whether someone else has posted up some results with that engine/turbo combo. The rest of the mod list really doesn't matter except to determine whether the fuel and ignition and so on are good enough for the power level.

Mines ECU wasn't glued I had a new chip put in. Yeah bit of lag with that turbo haha.. As long as I'm over about 250 260rwkw ill be stoked.

Depending on what spec T04e it actually is - will depend if you'll get there.

There was something like 30 variants, as they are from the 1970s... So lots of wheels/housing combo's around. I think you'll be struggling to get 260rwkw, and it'll be laggy.

Yeah I wouldn't have a single clue to what spec it is.. Kicks in at around 3600

I suggest getting rid of the turbo and getting one suited for the 2L motor, then get a nistune or an aftermarket ECU as the mine ECU won't be tunable and will probably ping/do all sorts of weird shit as soon as you start putting any decent boost into it, could even pop the motor if it is highly advanced.

I had a mines ECU in a car I bought about 5 years back, the previous owner had retarded the base timing back as far as it went just to stop it pinging, it also ran so rich that it went off the AFR scale when on full load, below 9:1, basically they are just crap and not suited in anyway for what you have.

there are a thousand T04E variants as stated. not all are bad and plenty of people have had them work without a drama. kicking in at 3600 is fine if thats when it starts to pull hard id be happy.

find out what T04E it is and go from there. hopefully its one of the common ones.

I recommend changing the ECU for a nistune at minimum and you will probably be limited by injectors before anything else.

My tuner said it will be tuned to whatever is in the tank.. i said i didnt think that was possible.. Anyway I'm over talking about my ECU, if my tuner has lied well.. I ain't going back...

Lol, is there a way by found out what variant is it WITHOUT pulling it apart? Probably a stupid question but I'm here to learn..

No factory ECU can tune/trim the fuel on the run, which is what he said he has been told... Or perhaps it was bad describing on his behalf.

What about the chip he put in? Can that make a difference to the pinging.. This is f**ked lol

People need to start reading ALL the posts.

OP says Mines ECU chip is not glued in and in fact another chip has been put in there. Therefore it is possible to tune that ECU, either by the shitful 90s method of burning EEPROMS, or by putting in a Nistune board.

/ ECU problem

Turbo still an open issue.

Yeah and read the subsqeuent one where he states it will adjust to whatever fuel is in the tank - that is simply untrue (and this is the part we are talking about).

It is a SINGLE tune option. You set it for say 98 octane - it is set for good.

Your current setup does not...

1. Adjust when there is detonation

2. Adjust for other fuel types in the tank

3. Adjust for changes to boost levels

Well I've spoken to him again.. He said its no lie? I'm going to get him explain to me properly how he did it.. I'm only taking his word for it and is a family friend.. So I don't see any point in him lying. I'm just going to punch him in the head if my car pings out lol

No, you see, I read that as meaning he will tune it to whatever is in the tank. Which is kind of what you have to do, no?

      I'm not 100% how the BMW racers do it, but I know from other brands like Merc, moving, and changing the coolers is one of the things. Like getting a transcooler out from infront of the radiator to out near a wheel arch. So some of the stuff you've got crammed in the middle front, spread it out and open up where you can in the bar to get more air in to the sides.

      Small update for the day... Turns out the intercooler and engine coolant hose kits are anything but complete....I probably should have counted better but it only really covers about half the coolant hoses in the car, it really just covers the visible stuff and pretends everything else doesn't exist (turbo water feed and returns and also heat exchanger lines through the 2 pumps and cooler) .In any case, I'm happier to have half reliable hoses than none, but a bit of a disappointment. Anyway...finger click (and 5 hours).....hoses in place, lots of spring clamps replaced with screw clamps, and engine coolant is on the pressure tester for the night.   Incidentally, upsized header tank is an Inifiniti factory option....not sure I'll ever do prod car racing in this but at least it is legal.

      Just weld it onto the hot pipe. If you want it right after the turbo, put it right after the turbo. Or rip the comp cover off and drill and tap a hole into it.

      hahaha glad I can rely on you two to go on a spiral at the drop of a problem! Some quick answers....the ducting is excellent top bottom and sides....everything that gets in goes through the coolers (noting the oil cooler redirects it out again, fair call if it is cooling 120o+) and the heat exchanger for the intercooler also has some scoops to pick up more than it's fair share too. I can't see going down the water spray track....no bueno for formal racing and a big risk for long rally days if you run out (plus I'm not clear if it is allowed there either yet).   Frankly, it must be possible to reliably put 400kw through a standard front end, the BMWs do it so I just need to work it out....I'm starting with reducing blockages in the way and adding some coolant capacity with a bigger header tank, flushing rad and making sure it was filled/bled properly (I didn't do the last coolant change); also taken measurements incase next step is a bigger/higher capacity custom radiator

      R32 GTR Limp Mode?

      By Duncan · Posted

      wow, a completely stock GTR! I've got to admit, I have no idea from what you are describing....do you have  any idea where the "thump" comes from, and are you certain it is the HICAS light not something else like the cat overheat light?
