Rb26dett R32 Gtr Questions

[drftking]

Hello all,

I just need to know a few things about my RB26 as i havent had a real lot of experiance on these motors

I just need to know what i can do to keep my engine in one piece .

as far as i know it has been tuned with a Nismo ECU, it has standard fuel pump, standard injectors and standard fuel rail.

The car has been Dyno'd and has put out 297rwkw. I have forgoten to mention that it has the N1 turbos on it and is running 18psi.

What i need to know is, is this boost to much?, will the car see around 330rwkw with a injector and fuel pump upgrade?

And at what stage do you need to start worrying about touching the internals?

Also the engine is out of a R33 GTR and has done around 62,000kms.

I wouldnt mind a bit advice on oils and what not just because this is my first GTR and i really want it to last but also want a fair bit of power

Thanks in advance for all your advice.

Cheers

Injectors and fuel pump by themselves won't gain you any power, but they will give you the fuel you need to run more boost and make more power that way. Not sure about the N1 turbos, I thought they could handle 28psi but I really haven't looked into it, only heard someone mention it. Some of the other guys on here will be able to tell you more

i use 0w40 oil

make sure your A/F's are good

don't limiter bash

remember excessive rev's kill these motors.

personally i wouldn't go past 20psi on stock motor

If it were mine i'd have a tuner run it on the dyno to check that knock levels and injector duty on the current setup is safe. If the motor is truly at that kms and has been well looked (neither of which you *know*) then 330 should be ok if you keep it off the limiter. Other things you might need over the injectors and pump is AFMs and clutch. Thinking about leaving it at 300 if you're concerned about the engine - the lower the power the longer it will live, you choose how much risk you want to accept.

Read the oil sticky..... but IMO you want a fully synthetic 5W-40 or maybe even a 5W-50. Im using Mobil 1 5W-50 because its cheap and easy to get, would prefer a 5W-40 tho. Change at 5000kms. Overfill by 1lt if you're going to the track.

My R34 was originally tuned by Willall Racing for 320kw @ 1.2 bar and then tuned down for longevity .

keep it to 296 kw @ 1.15 bar , that will give a relatively safe long life .
