Forging Rb25 I Need Answers

[Turbz RB-25]

Hello skyline junkies!

I started a thread a little while back in relation to converting my engine to an RB26. I was pursuaded otherwise, and was told to just forge my internals and get a new turbo.

Currently I am running a HKS 2835 Pro S with all the other mods (PFC, exhaust, front mount, nismo 555cc injectors, boch 040 fuel pump etc etc) and making 273 rwkw, however, it's jsut not cutting it for me.

Now, I need some answers from you good fellas.

1) What do I have to do exactly to get around 350 rwkw? i.e. forge the internals, new plennum, new manifold etc?

2) WHat cost do you estimate ALL of this will amount to, I need specifics i.e turbo $3000, forged pistons $1500, installation et etc??

3) WHat turbo should I be looking at for around 350 rwkw? I've hear the GT35 is the go? But what brand? and what A/R ratio?

Please advise!

I had:

Pistons

GTR Rods

Tidied up head

The rest was factory.

As for the rest, GT35 you'll need, .82 A/R, and just the usual other standard stuff there are 1000 posts about.

How much $$$ ar we talking including install and parts for the pistons, rods, new cooler pipe work etc?

[R31Nismoid]

if you dont have the turbo etc and all thats included in the estimate

15-20k. You can easily go over 20k if you buy parts upon parts, but it comes down to if you actually need them

20k easily thats a lot of cash

20k easily thats a lot of cash

and after you spend 20k you will not stop you will always spend more always.

Buy a morris minor......you'll be so stoked that it is going you won't want to modify it. And every time you think about it it will break down on you and rob you of the chance anyway!!!

Otherwise, go the Gts30t.

Yeah but your's is auto. I am after a manual.

What sort of turbo you got on yours, it was a GT3540 wasn't it?

See the thing is, my car is not stock, I already got the foundation; Power FC, Nismo 555 injectors, bosch 040 fuel pump, 3.5" exhaust, front mount, splitfire coil packs, Jim berry 'full monty' clutch. Plus, I should be able to sell my turbo (GT2835 pro S) for around $2800.

So if you spend $23K on yours from stock to what it is now, if I do it, it should be something less yeah?

[R31Nismoid]

Probably not a lot less.

Your only saving what, 5k or there abouts (injectors 800, PFC 1400, pump 200). I dont include anything else as coil packs aren't always required... and exhaust because everyone has one.

Although not sure about 2.8k for a 2nd hand HKS turbo, i could be wrong

Just because he has an auto box on the back of it doesn't mean you have to use the auto. The engine is the same regardless of what gearbox he was running.
