Starting the rb25 build on my r32/4

[RSi]

Like others mentioned, injectors seem small. Especially paired with a T70...

Are you going to put the back of your kit on your car?

we're not knockin ya bruh'
...the more BHP the merrier imho!

but like mentioned, SO MANY different variable. A member of GTRC (ChasDuran) just went through a crapload of hell for 400HP using a ViPec plus other parts internally and externally, so you may consider speaking to him as he'll have a great idea for what your after.

I didn't go about it the hard way.. I trusted a shop to get me 400whp, and supplied the cash. THEY went about it 'the hard way.. and still left me with final numbers of 365whp.

hey here we go.....

well i dont mind the feedback. and i am going with a bigger set of injectors for the 25 I will be getting a nice set of greddy 550 cc injectors for the car. 444cc will not be enough by any means. Thats why i recently changed my mind. I have bigger power goals now. I can't stop myself.

Does anyone know if i can use my rb25 ecr33 powerfc to work the vvt as well? I know this has been a problem or itleast some people had confusion with this issue. Anyways keep the feedback coming guys : )

Also yes i will definately be putting the rear of the kit on. Will look sweet this year guys. Speaking of which does anyone know where i can get my valve covers ainted for a reasonable price?

[cschepp]

oh and i have now put the subframe back on the car and it is rolling around the shop. : )

[Zacho]

Is that an ebay turbo?

Looks like you have a nice work area.

If you're going for 500 whp, I'd go for more than 550 cc injectors. In case you end up with more power than you planned for, you won't be stuck spending more money on other injectors.

[RSi]

yeah I'd go 740 off the bat...

[BrianV8]

I have 550cc injectors running 81% duty cycle and putting down 400 to the wheels. Factory internal rb25. Just make sure you have the z32 maf and your good to go

[ChasDuran]

Shadybeaverguy is right.. You should only run injectors constantly around 75% of max capacity, or you severely shorten their life expectancy and efficiency. Last thing you want is to run lean at 500hp and ruin your engine.

1cc = 1hp is the general rule at crank I believe. So 500whp, about 600crank.. 760cc are comfortably in the 75% range.

I have done a LOT of studying since getting shafted due to mechanical ignorance.. I would suggest you read up on it too, just in case.

[cschepp]

ok i will go itleast in the 700's for injectors for sure.

Zacho- this is an xs power turbo not sure if it is an ebay one but i did get a resonably good deal for this. And besides if i blow the thing apart i will just upgrade then.

Anyone know a good painter? I want my rb26 covers to go r34 red.... please let me know i will ship the covers out to you and pay for everything.

And ya the shop that we got is a very nice shop. We have our own hoist and air compressor so the engine drop was alot easier than the one we did in my buddies driveway!

Anyways keep the feedback coming,

Thanks,
Chris
