R33 Gtst Power Upgrade

[fitzy's auto parts]

hey guys i only just joined sau and im also a turbo virgin! only ever owned v8's, i have just bought a r33 gtst that im turning into a track car. i after some advise and helpful hints to doing a power upgrade. the mods that is on it atm, is exhaust and pod filter only to my knowledge. im told with doing fmic, injectors, afm, ecu, turbo and ebc, i could get a comfortable 300rwkw which is what i want! i would like to keep standard exhaust manifold if i can and just bolt a newer bigger turbo on that. i am also looking at a power fc d-jetro, is this a good ecu to choose? also what is good bang for buck? can i plz get some advice on what to do and buy to make this power?

Look at the rb25 dyno results thread. All the info is there ready for you to figure out what you want to do.

Turbo selection for track work can be hit and miss, you will need a larger rear housing to reduce exhaust temps at the very least.

Are you considering e85? That will also change your turbo selection for 300kw.

GTX3071 0.84 rear, low mount stock mani, E85, done.

Look guys I really no f**k all about this hence the reason of getting advise from you guys! I bought the power fc d- jetro ecu today. The guy I bought that off said get a rb25det neo turbo and hiflow it! Reckons that will give me the power I'm chasing no worries!

What cc injectors should I get and what brand? The 255 fuel pumps on eBay are they the ones to get? Says there good for 550hp?

[Josh080691]

Get a walbro 255L and 740cc nismo inj if ur still side feed

thx for your help josh!

[Dose Pipe Sutututu]

for what it's worth, just go top feeds...

[AngryRB]

If its a track car then the rules change, it will spend a lot of its time in the top end, this is where a GT35 sized turbo and some 1000cc topfeeds come in along with the usual support mods, later when the motor blows, consider slapping a RB30 in there and you'll be able to re use these parts to push 400kws.

You could use a 0.63 rear for the RB25 and a 0.82 for the RB30, win win..

does the d-jetro even work on a GTST?

[Joshbigt62r]

Couldnt agree more with Johnny on the top feeds!

[Joshbigt62r]

And as far as im aware there is no d-jetro version for the gtst.

ok guys you are worrying me! will the ecu i bought work for me and i have bought everything now accept injectors... i keep getting told 2 many different things off to many different people... so i have been told to run 2200cc injectors which you can buy brand new bosch ones on ebay with loom for around the $750 mark! so my next question what diameter are the the gtr rails where the injector sits in 11mm? and will a gtr rail fit on my rb25det engine with the standard type inlet

manifold?

[GTSBoy]

You do not want 2200cc injectors. They are massive. Any Bosch EV14 based 1000cc injector will be fine though. I would choose an EV14 injector over any old tech injector ANY day of the week. Except for one problem. Old RB25s have side feed injectors and if you want to run decent new injectors you wil have to convert to top feed, which is an exercise. Contact Scotty (he's even posted in this thread!!!!!) for what injectors and gear to convert will cost you.

Thx Gtsboy! Yeah already have done that cheers mate

Hey guys just bought a r34 wreck and was wondering if the rb25 neo long bare engine can be swapped into my series 1 r33 gtst as I have heard there a much better engine?

[GTSBoy]

Yes it can.

But....you'd be mad to just swap the bare engine over. All the sensors and actuators and so on a sufficiently different (and newer) that you should swap in everything. Engine, sensors, loom, ECU, power steer pump, AC, the whole lot.

[fitzy's auto parts]

So your saying it's all compatible then? Coz I have already bought the power fc d-jetro to suit my setup and I have heard people say there not the same?
