Hi guys I have afew questions to ask so hopefully you guys can help me out here.

First of all I want to get a r34 but there isnt any on sale and if there is they are over 30k+
So I want to buy a 25gt for the look.
I want to have a awd instead of rwd however I looked around and found there is too much f**king around and costly to convert rwd to awd

So I was thinking about getting a 25gt 4 since it comes stock with awd However I'm not sure if they come turbo as well I could only find na versions...

I would like to have around 300rwkw after modding

if anyone could list me down the specifics and also how much $$$ per specific mod would cost to turbo from na or upgrading the already turbo 25gtt parts to make around 300rwkw

I would appreciate it.

So my first question is Am i better off getting a 25gt4 and putting a turbo onto it and just upgrading the internals and doing everything at once to make 300rwkw ' How much am i looking at per specific part/mod + labour and tuning ? and is it going to be cheaper to make 300 whp ?

Or

Am i just better to get a 25gtt rwd and just work on it to get around 300rwkw ' How much am i looking at per specific part/mod + labour and tune ?

Or just buy a already modded 25gt that is pulling around 200rwkw for around 20 grand ?

I was thinking about buying a 25gtt or 25gt4 at around 10k then spending 10k on top for more power

which would be cheaper and more cost effective

My spending money will be around 10 grand.

Sorry for all the noob questions


Please dont spam random crap if you have no idea what you're talking about or have nothing to do with the questions asked.
Cheers

You could answer all of your questions with information both on this forum and on google but okay...


Buy the GTT and live with 2wd or buy a GTR

Turbocharging your NA GT-4 is not really a good idea, you'll need to buy a turbo engine, turbo, manifold, turbo lines, injectors, fuel pump, ECU intercooler and have it tuned before you can even drive it, then you'd probably want to upgrade your brakes to the turbo brakes

Because you asked for costs ill give some estimates

RB25DET NEO Engine $1500 (give or take, healthy low km or rebuild will throw costs out)
Turbo $1000 (buy a turbo then send to hypergear for highflow)
Manifold Stock or custom $50-1000
3" exhaust $500+
Turbo Lines $200
Injectors $600ish
Fuel rail $250ish
Fuel pump $150-250
ECU too many variables from nistune to standalone
Z32 afm + plug if required $100-300
Intercooler $200-500
Tune $600+
Turbo piping as none of the NA stuff will work, budget $400


If you want 300kw from an R34 GTT just buy one, front mount highflow turbo and 3" exhaust with a nistune will net you that.. almost anyway

Intercooler $200-500
Turbo $750 (send to hypergear and highflow)
3" exhaust $500+
Injectors $600ish
ECU too many variables from nistune to standalone

Tune $600+

    • The wiring diagram for the R33 RB25 is freely available, and is essentially the same same as most other RBs (just with differences as to which pin # does which job). To get the ECU to power up, you just need to provide power to the ECCS relay, and have the other power feeds that come in from the top left of the wiring diagram (wrt the ECU) that give perma power to the fuel pump relay, the ECU itself, etc etc, all connected. When you put power on all these it will just come to life. It's pretty clear from the diagram what needs to happen. Just follow the lines from the 12V + supply stuff in the top left over towards the ECU. I've even posted snips of such diagrams (not for vanilla 25, I think for Neo and 26) to various threads here in the last few months, talking about what it takes to get the fuel pump and FPCM up and going. Search these up and they will help get you started on doing the same with the vanilla 25 diagram. Hell, for all I know, I've done the same with that one in years past and have forgotten.
    • Yep...so unless someone posts up the answer you will need to probe from the ECU connector to the dash plug with a multi meter in continuity mode to trace the wires.  Note the ECU has multiple - and + (and across different key settings - Battery, IGN and Start) and most likely the power is fed from the connector(s) that is normally near the left hand headlight.
    • Thanks Duncan, I am actually just trying to get the Rb turning and running with the RB25DET S2 original loom itself  I am just trying to get it going outside the body and not thinking about the S15 or trying to match anything to the S15 loom at all I am only trying to see if anyone has done this and what pin they found to be the ignition trigger and ECU+/- on the dash connector, that's about it. Thanks  
    • Hi Guys, Does anyone know any aftermarket part numbers for a starter motor to suit the VQ25DET? I can find lots of alternative part number for the VQ35DE, which I assume would fit, but there is a lot of conflicting information out there. Thanks..
    • I don't understand how this hasn't boiled down to - Upgrade the turbo when you have everything required. ECU, injectors, fuel pump, turbo, etc. Do it all at once.  If you don't have everything required, just enjoy the car as it is and keep saving up your pennies.
