drivetrain for a turbo B18b

[[SDCTVE]]

ok guys, i need some technical advice here.
i got a avo stage 1 turbo kit on my DC2
internals are stock, but im hoping to get a rebuild with forged pistons and rods as soon as i find a decent worskshop.
im hoping after that, the block can handle about 12-15psi comfortabely.
im aiming at about 170kw atw
atm im running a piggyback ecu with a 5th injector.
but what about my gearbox?
what sort of upgrading will it need to handle all that power?
and is the piggyback ecu enough?

anyone else with a b18b turbo?

you wont need forged internals if you only plan to get 170kw.

spend your money on proper engine management and a good tune.
You will also want to upgrade the turbo that comes with that kit. I rekon its too small for the target power you're after.

This is MUCH more limiting to your reliable power production than the stock internals

firstly, the turbo that comes with that is a garrett28 ball bearing turbo, thats a decent size turbo man, its the same turbo in a s15 pretty much.
and if i want the block to last dont i need to change the internals???

It's NOT a big turbo man.

The stock sleeves and rods/pistons will take 12psi. You will need a larger turbo than the tiny baby GT28 if you want to get close to 170kw on a SOHC.

ive seen it done. 170kw from a gt28 is do-able!. im definately gettin a rebuild with forged pistons and rods....maybe even 440cc injectors. i just dont know about my ecu or the gearbox

[ProECU]

Goodluck. I'm sure you'll get there, I was giving you the cheapest & easiest option.

With a rebuild as planned, i'd be dissapointed with 170kw

The S and the D keys are pretty close to one another

SOHC

yeah my mistake. I still stand by my original comments, there's an easier way to get 170kw which will cost him less than his planned route.

end of day, his build, his ca$h, his decision

ok... maybe i left out that my bottom end is on its way. which means i either rebuild with stronger internals or get another b18 dropped in....

[tinkerbell]

either way, sounds like an expensive route...
