SPOOL RB34 Stroker Engine into GTR

[Turbo2.6L]

Anyone used one of these or looked into them? They claim that they're safe to spin to 9000rpm, so seem to be a decent option for the coin...
One of these with a decent sized huffer on E85/E100 would be an animal in comparison to a 26 one would think, having loads more low/mid-range power & torque as well as an increased peak figure.

Had a brief look at RB28 packages & decided i am either not baller enough or not stupid enough to endeavour on such a project just yet :D Haha

RB30 stroker for the win

Last time I saw there was only 1 result from the motor, eg. not much testing

You're cashed up to the hill though so give it a crack :)

Otherwise best option is probably a RIPS RB30

I actually agree with Simon .....

Had some less then ideal dealings with Spool in the past. Afaik its all china copy parts.
Not to say it won't work though :)

[Turbo2.6L]

Me cashed up?? Lol
Was originally looking at RIPS long motor, but wanted more info on these before i made a decision. If you can get an engine with ~15% more capacity & still rev it just as hard for similar $$$ (reliably that is), it would seem like the better option. Don't want to get one & spin it to 9000rpm on first time out & pop it, so thought i'd ask the question first.

Also, can anyone confirm that a 26/30 combo will go in a 33 without needing to modify anything due to increased height of block?

[RH8 GTR]

Not sure how many Spool 3.4 kits have been sold, but i remember seeing a dyno graph from their 3L kit to this 3.4L, with identical bolt ons.

Difference was fairly decent from what i remember.

Although it was a long time ago, my RB30 was built by Spool imports, then rebuilt by C-RED here in Perth, said they were impressed with how it was put together / clearances etc

Results between the 2. >> http://www.spoolimports.com/articles-1/rb34det-results

Also, in an 32 GTR, it has bonnnet clearance issues, in an R33 i believe there is no issue. If you hold of for a month or so, i can test fit mine and close bonnet!

[Turbo2.6L]

Yea seen that comparison on the Spool site, but doesn't really give an indication of longevity or even go close to 9000rpm. Not that i need to spin it that hard, but i'd definitely like to go 8000+ with the T88 hanging off the side...

[RH8 GTR]

Yeah, have not seen any other results as of yet.

If i had to do it again i would get a RIPS 3L, Spool dont supply the option to have billet main caps and girdle. Where as RIP do, much stronger setup!

Space is tight on R32s, R33 & R34s seem to be fine.
Can't remember you turbo config, but some HKS single manifolds push the turbo quite high and could be a problem, stock twins can reuse stock lines with a bit of care or thought.
Lower GB belhousing needs modification regardless of gtr model, front pipe / dumps will likely need extending also.

If you want 9000rpm, go the Spool or Nitto 3.2L stroker and I would go a billet mains for insurance.
If you can settle for 7.5-8000rpm Spool 3.4L are good to go.

A stroker will usually add about 2-3K to the price of the setup (basically the crank's value)

Either a well built RB30 (eg. RIPS) or a 3.2L stroker would be my preference, add vcam if your a true baller :p

[Turbo2.6L]

Sweet, good advice!
Will pass on the V-cam setup for now though...
