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?

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.

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!post-135918-14076767476698_thumb.jpg

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..

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?

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.

    • Didnt realise RB's had more then 1 head.
    • I'm normally copping my own abuse from neglecting my daily drivers. "Those suspension bushes will last a bit more", "Don't worry about the oil leak, just keep topping it up". The project cars I'm always doing things slowly on them as I'm wanting them to be done better, and neater, and nicer. Luckily I don't have to deal with 18 year old Matt's "Learning to wire" stuff in the project cars. And there's only one piece of wiring I'm displeased about in the Landcruiser, and it's about to be cut out... However, the box loads of parts that have been going through this place lately for the Landcruiser... Brake pads Brake Rotors Full handbrake overhaul Wheel Bearings Seals Swivel hubs Steering Boxes Half the suspension joints Shocks Air bags (Ones to go in the rear springs for towing) Water pump Timing kit Lower timing case Harmonic Balancer Radiator Lots of other little seals and shits Gas struts for the bonnet New power window switches And god knows what else I've forgotten... Ha ha ha I have my fingers crossed the pinion seals don't start leaking on the diffs, that the transfer case doesn't leak, and the gearbox input shaft doesn't leak, nor the rear main seal. As they're about the only seals I haven't replaced in the driveline! I'm seriously eyeing off buying new caliper rebuild kits front and rear brake calipers... I'll probably recheck all the valve clearances soon too, and hopefully, it should be all good and sweet to haul some long distance trips again!
    • Every time I pull my 3x gauges out of the console and see the crack-addict way that I did the wiring, and I just can't bring myself to tear it all apart and "make it nice", because it is currently working. In fact, the last time I was in there I probably made it worse.
    • The best part is when you own the car long enough that you look back and find your OWN ham fisted amateur shit!
    • The annoying part about neglect, is when you start to replace one thing, and find ten more broken things. Ham fisted monkey repairs you normally only find out about when trying to do something unrelated! Ha ha   Neglect you can kind of anticipate the huge costs to fix it all. Ham fistedness is normally a shock the first time your work on a new old car, as everything "looked" good before.
