Bigger Displacement

[CosworthSti]

What's the biggest displacement I can get for the R34 from the RB26 (big bore, stroker etc) I know HKS had a 2.8 but isn't there a 2.9 or 3.0l?

[tridentt150v]

OS Giken 3.0 litre kit for around the $20K mark. But there are bigger kits than this..........Spool was looking at a 3.2 and a 3.4 kit.

[tricstar]

just noticed " BoostdR " on here has a RB31DETT ,, not sure how you get that... I got RB28 and that is a noticeable difference from standard on and off boost, so an RB31 would be awesome,

[3LGODZILA]

the 3.2 and 3.4l kits by spool are for rb30 blocks not rb26

[Moodles2]

As for the RB31DETT, probably a RB30 bottom end stroked out to 3.1 and a RB26 head for the twin turbo

$20K!!!!

or Rb30 for $200 (or realistically $5 to $10k fully forged and balanced etc)

[JonnoHR31]

$200? it'd wanna be one hell of a good 30e for that. myne paid me to take it

3L block or if your state doesnt allow it

a 2.8 or 2.9L stroker!

Charlie still has his apexi 2.9 kit for sale.

There is also some company out there that is de-stroking rb30 cranks to 83mm, running standard rb26 rods and custom pistons to make an RB29.

User 'Mark99' on this forum was the machinist that developed the stroker kit from memory. I cant remember what the company was called though.

[MEKTIK]

Stick to the rb26 and stroke that

I think he worked for Rhemac in Adelaide.

go the 26/30 for sure...is this for ur carbon weapon lol

[UWISSH!]

nitto have just released a 3.2l kit but i duno what sorta price they want for it

[tridentt150v]

the 3.2 and 3.4l kits by spool are for rb30 blocks not rb26

Yep, not sure if they will adapt to 4wd, but I'm pretty sure it has been done for the rb30. But I've got a funny idea that the 3.2/3.4 crank throw will not allow the 4wd front housing.............did I read it or am I dreamin' - can somebody correct me???

Carbon weapons is looking bad, I seriously didn't realize the cost of carbon, sure I knew it was expensive but $20k for a bodykit with a saving of less than 100kg, THAT'S INSANE!!

[bubba]

RB30DET FTW!

That RB31DETT will just be a slightly overbored RB30.

Nitto do the 3.2L kits for RB30 (soon?)

Spool do the 3.4L kits for RB30 (soon)

And I think RIPSNZ do a 3.2L aswell?

OR save your money and just built an RB30DET.. you'd only need the extra 200-400cc if running a HUGE turbo.

P.S. I love my 30

RB30 block with sleeves and over size psitons is a good start for one hell of a strong 31 or 32

[pipster11]

love the comments on the rb31 block

i read his thread the other day

he has made it an rb26 open deck with new sleeves, rods and pistons and an rb30 crank

give a better bore-stroke ratio or something and is designed for driveability, torque and response

he has put a lot of work into it but its still in testing and will eventually be on sale once everything is tested thoroughly

on topic, if you want more displacement then you can't look past an rb30 with the 4wd adapter

r.i.p.s in nz will make you a forged bottom end with the adapter and ship it to oz, bolt it in, add your head and away you go

[WHITER33GTS-T]

There are a few places now that do a RB30 adapter to run awd. Id say get a dirty 30 bottom end and a Nitto 3.2 crank. They say its good for 1200hp and 10,000rpm.
