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.

    • It is a kunfine Android screen . Does anyone know the wirering diagram of the fuga ??
    • just an update to this, poor man pays twice  Tried sanding down the pulleys but it didnt do the trick. Chucked another second hand alternator in the na car which I got for free off my mate and its fixed the squelling. Must have been unlucky with the bearings.    As for my turbo car, I managed to pick up a cwc rb alternator conversion bracket + LS alternator for 250 off marketplace, looked to be in really good nick. Installed it , started the car and its not charging the battery.... ( Im not good with auto elec stuff so im not sure if this was all I needed to do but I verified such by using a multimeter on the battery when the engine was running and I was only getting 12.2v )   I had to modify the earth strap for the new LS alternator , factory earth strap was a 10mm bolt which did not fit the bolt on the LS alternator which was double the size so I cut it off , went to repco bought some ring terminals that fit, crimped it onto the old earth strap and bolted it up to the alternator , started the car and same issue. Ran like shit and was reading 12.2 at the battery.  For a "plug and play" advertised kit thats not very plug and play but alas.  My question is , am I missing something ? Ive been reading that some people recommend upgrading the stock 80 amp alternator fuse to a 140 amp but I dont see how that would stop the alternator charging especially at idle not under load.  Regardless ive pulled it out and am going to get it bench tested by an auto elec tomorrow but it would be handy to know if ive missed something silly or have done something wrong.   
    • My wild guess is that you have popped off an intake pipe....check all of the hoses between the turbo and the throttle for splits or loose clamps.
    • Awesome, thanks for sharing!
    • To provide more specific help, more information is needed. What Android screen? What is its wiring diagram? Does the car's wiring have power at any required BAT and ACC wires, and is the loom's earth good?
