Sorry to crash thread but i'm trying to find some quick answers without starting a new topic. I have an R33 GTS-T with a GCG Highflow turbo (XTRGTST). What power range could I excpect to get out of it?

ok so i cant wait for the ol' 30 to be built, i have got my walbro e85 fuel pump and my injectors will be here next week then its off to Jez to get this happening

should all be done in the next few weeks so il post up the results...

Has jez touched you your car yet?

Yes he did....it felt good he said

For some reason it was running out of fuel, wasn't the injectors coz they were at 75%,

Made about 360ish at wheels.....we did see more then 370 though

Gotta run a few tanks of ethanol through it, change the filters/clean the fuel filter sock and go back to make sure everything is 100%

Huge difference in torque and thrust lol

What tends to break on these at this power level? Do they normally just spin a big end or do they throw a rod out the side of the block haha?

Im running a 35r at the moment with just over 500hp and was thinking about changing to e85 for a bit more but a bit unsure if its going to hold

up to the extra power or not and what will break if it doesnt.

e85 would allow you to run a much smaller turbo for similar power levels, making the car much more responsive and faster overall.

Who knows what will break and when, but at least there will be no DET which is what usually kills motors, built or stock.

Ethanol will give you more torque, but the way the power is released during the stroke should help with longevity, and your exhaust temps should be around 200c lower also. The only real downside is less K's to the tank.

So do you personally think it's worth pulling the motor out just to do the same oiling mods that you did and chucking in some new head studs and head gasket?

Haha your recent results Simon was what inspired me to put mine on e85

If you are prepared to build the motor but want to try and get away without you can always try.

Whilst the motor is good for the power in described trim you should bear in mind that the longevity of the motor is also largely dependent on condition and the life up to that point. Much like tests on SR20s, lots of people kill them at 200kw and then others have tested them to 400.

Be it myself I would stay within the known constraints but would boost it till it blows. However I would be prepared to replace the motor should it grenade.

GL and keep up posted :)

Yeah i have the mindset that I'll have to build the motor eventually and to be honest the car really doesn't see a real hard life. Simon you did oil pump gears and bigger sump if i remember correctly? Did you change these yourself?

    • Has equal chance of cleaning an AFM and f**king an AFM. I think you can work out what happened. When the Hitachi ECU sees the AFM die and goes into the associated limp mode, then it will start and run just fine, because it ignores the AFM and just runs on idle maps that will do what it needs to get it going. But there is no proper load signal, so that's about all it can do. My suggestion? If you don't want to go full aftermaket ECU, then get some R35 GTR AFM cards and some housings to put them in, in the stock location, and Nistune the ECU. Better to do a good upgrade than just replace shitty 40 year old tech with the same 40 year old tech.
    • So my car was recently having trouble starting on initial crank, I would need to feather the gas for it to start up but besides that it would start and run fine. So I clicked the idle air control valve (with throttle body cleaner) and cleaned the MAF sensors (with MAF cleaner). The start up issue was fixed and now the car turns over without the assist of the throttle, but the car is in limp mode and wont rev past 2.5k RPM. From what I understand the IACV would not put the car in limp mode, so I am to believe it is the MAF sensors, but it was running fine before and now I cant get it out of limp mode. I cleaned the MAF made sure the o rings were seated properly. Made sure the cables were plugged in properly, the cables also both read the same voltage. Does anybody know why this is or what could be causing this or how to get it out of limp mode?
    • Ooo I might actually come and bring the kids, however will leave the shit box home and take the daily
    • Thanks. Yeah I realised that there's no way I'd be able to cover the holes with the filler, it would just fall through. Thanks again @GTSBoy!
    • That was the reason I asked. If you were going to be fully bodge spec, then that type of filler is the extreme bodge way to fill a large gap. But seeing as you're going to use glass sheet, I would only use that fibre reinforced filler if there are places that need a "bit more" after you've finished laying in the sheet. Which, ideally, you wouldn't. You might use a blob of it underneath the sheet, if you need to provide some support from under to keep the level of your sheet repair up as high as it needs to be, to minimise the amount of filler you need on top. Even though you're going bodge spec here, using glass instead of metal, the same rules apply wrt not having half inch deep filler on the top of the repair. Thick filler always ends up shitting the bed earlier than thin filler.
