spools rb34 stroker kit is finaly on sale

http://www.spoolimports.com/content/SPOOLN...TROKERCRANK.asp

price is $5500

mods please dellete if other thread has been made already

Good to see this kit available at last! Have to say 450kw is somewhat underwhelming but the extra capacity will have to translate to more power. It will be great to see someone build either a drag or a circuit car and see what it is really able to do!

[sleeperdatto]

please note this is on pump fuel with a rb25 head

another note is that the builder needed to get a new clutch because of the extra torque

hope to build this in the future.

With the length stroke it has not sure if you would want to rev it anymore than 8krpm; 608hp is what you could make with a RB26 but it would no doubt come on earlier.

I am sure it is capable of much more. The 3L going into my Stagea is looking too small already!

[WHITER33GTS-T]

Nice. Now all it needs is a more modded head and a turbo upgrade. Cheap as chips price.

Its a sad day when 608hp/450kw doesnt impress.

That said, im sure Brad couldve got a T51RSPL on there at 2 bar on e85 if he wanted a big number, surely the point here is just crazy low end grunt more than a big hp number

[bubba]

I believe the point was to compare the identical setup from the 3L to the 3.4L...

it was see the website in the first post

[WHITER33GTS-T]

Is there a dyno sheet for each bottom end to overlap the different results..?

[N1GTR]

Yeah that's what I'm looking for aswel

Brad comes on here every now and then, surely he'd be happy to post them up

thats what i thought too.....

[STATUS]

cant wait to see the torque comparo

[sleeperdatto]

yeah id like to see the power curves on this engine.

he was making close to 580-590hp with the 3.0l so this is a great improvement especialy how it is relativly cheap comapeared to a full house jap bottom end.

probly total cost for the whole engine is 6k - 10k by guesstimation.

[TiTAN]

considering pistons and rods are about $2k on their own you are only up for the 3.5k billet crank over a normal forged 30.

There is a price at the top of $5500 for the rolling assembly so you would have to say closer to 10k all up ready to go depending on how far you go.

[zebra]

I wonder what the SAFE rev limit is on these without the Billet 4 bolt girdle.

[Weapon]

WOW still AFM equipped

Would be good to see with a further worked head on it and +1 on the dyno power and torque graph overlays on the 3l and 3.4

RB34DET Results

RB34DET 'vs' RB30DET

The RB30DET boost and power curve is in green and the RB34DET is in red

A comparison between the old RB30DET engine and the new RB34DET stroker engine is complete. The two engines are identical in every way except for the new stroker crank set up. The purpose of building two near identical engines was the only real way to make a true comparison between a RB30/25 and a RB34/25.

We arent trying to make the most power or we wouldnt be using pump fuel and a medium frame old school T04Z, we are trying to make a comparison.

Straight from the horses mouth.

[Trozzle]

Jesus that's nice.
