What fuel pumps and injectors are you guys running?

I'm looking at a Bosch 044 and some Sard 660cc twin sprays..

[Bl4cK32]

044 + rx7 series 5 550cc injectors.

[GTR-Ben]

GTR pump + Apexi 600cc. Will upgrade to another external 044 or similar later.

[Fitzpatrick Speed Works]

mallery 140, 2x Bosch 044, and 6x rochester 1400cc injectors!!!!

this may have been covered, but is there a way of telling the rb20det head from a rb25de head? is there any stamps on the 25de to say its a 25de head.

thanks

[Bl4cK32]

numbers cast into the front left hand side of the head i think. That and the visual size difference of the valves.

[Gradenko]

Not to mention combustion chamber diameter. 86mmish for the 25/26/30.

what size turbo do u guys recommend for a rb30det to produce 450hp??

[retrotec]

GT30 should be up to the task.

[RB30-POWER]

450 at the fly or at the treads?

[masTers]

Been told a GT30 is ample to produce 300rwkw, which is all im chasing

But i'd recomend upgrading to forged internals mate

[StockyMcStock]

i wouldn't say "ample", but it will certainly do it with a minimum of lag. it's about the smallest turbo i would recommend for such a power level, which is to say that is exactly what i would use.

After reading a few other threads, is it possible to use the R32 GTR Oil Pump WITHOUT need for a crank collar?

Yes, I have an R32 GTR (RB26DETT) oil pump on my new RB31DET:cheers:

[dnb]

just a quick one here guys. i have 3 oil pumps to choose from with my rb25/30 engine.

rb30et, r33 rb25de and r33 rb25det.

which one should i use?

cheers

[Sydneykid]

First choice = find a standard R32GTR oil pump

Second choice = RB25DET oil pump

.

[Cubes]

I went for the RB25DET pump.

I decided the least possible pressure placed upon the small crank drive with the highest possible flow the better.

cheers guys:)

[GTR-Ben]

I traded my Jun oil pump for a stock R32 pump + cash.. figured I didn't need to be too over kill..
