Hi all,
First of all, this is my first post in SAU, however, i've been reading a lot of posts on here and thank you very much for all the helpful information provided by all the members.
I'm in the process to a new project for my track car. And the purpose of this track car is mainly for Drift. Hence, it could be a different setup than most of the other conversion (Maybe?)
I am aiming for 350KW to 400kw at the wheel. And reliability is a major issue
Got a Rb26 head in my garage and about to purchase a RB30 block. Doesn't matter a series 1 or 2 as just the matter of drilling and tapping i assume.
However, as my main concern is the bottom end that should i fully rebuilt it or just recondition the standard RB30 parts.
I found out the RB30 standard parts are not ideal to high RPM rev, as i think they are only safe until 6500rpm. (Not good for drifting)
So if i rebuilt the whole buttom end with forged piston, aftermarket rods with standard crank, does that mean i can rev it up to 7500rpm or even 8000rpm safe?
Here are the specs i'm thinking in my mind:
Head:
RB26 Head (Pretty much bolt on to the RB30 Bottom End)
Need Oil drain back from head to sump.
Currently have N1s with standard maniford. Obviously have to use bigger turbo to achieve the target.
Prefer twin setup. Maybe Disco Potato ?
(Would like to have nice low torque and smooth top end power as well) Easy to handle :laughing-smiley-014:
Bottom End:
Oil Squirters? (Some say no, some say yes. I know it's hard to put them in but is it neccessary?)
Need good conrod bolt. (Any suggestion?)
Nissan Big Bearing will do the job.
Piston:
Should i run aftermarket? If so, which one? Some people put RB25 Piston with 20 thou, i think they are Wiseco. (Good Setup?)
If not, what would you all recommend?
RB30 Standard Piston? I know it's good to have they ceramic coatin the piston crowns and oil retention coating the piston skirts. But is this goanna be enough to handle the power?
So far i could not get the best compression result from my research. I think 8.5:1 is good? If so which piston i should use?
Conrods:
Should i use stand conrods and reinforce them?
Or
Should i use aftermarket conrods? If so which brand?
I found some conrods called SPOOL but wondering if anyone has use it before, Are they any good? On their website it rated 900hp plus.
Crankshaft:
That's the only part i could not find much information. Any suggestion?
Oil Pump:
Heard that standard GTR will do the job, but better to put a oil pump collar on it.
I am thinking to put a external pump as well.
I will convert to RWD, so i assume the RB25DET sump will bolt straight on to the bottom end. Correct me if i'm wrong.
Once again, thank you very much for reading this post. I know it's very long with so much question.
But any input or comment are welcome.
Cheers,
P.S. Anyone know where to get a cheap RB30 Enigne in SA? I found one for $395 from one of the wreckers. And maybe i can find one cheaper
Forgot to mention i had PFC dejetro (No AFM) and will upgrade fuel pump as well as injectors.
