Thread: Opinions Stroke or Bore

Because I have an excessive setup sat here.

Not interested in the money throttle bodies coat and I don't like the centre feed plenums.



That's the easy way out wheres the fun in that.

Previous build was just as fast as my friends DET on 10 psi

Det on 10 psi is weak tho..

You're right tho its the easy way out

86x88 he 249whp @ 172ft/lb 93oct all day long!!!

See 30-40ftlb more torque the stroker setup could give really appeals to me for a street car, which is predominantly what this will be.

A 92(s)x86(b) 2.135 motor will not produce much more torque than a 86(s)x88(b) 2.092 since both have same displacement!!!
You wont get 200ft/lb from a 2.1L motor a 92(s)x86(b) 2.135L motor still 2.1L unless you are talking 92mm bore x 86mm stroke!!!!

We have tuned here 86x86 86x87 86x88 86x90 86x92 and 92x92 and the only two that have break the 200ft/lb of toque are the 86x92 and the 92x92 wish are 2.3L and 2.4L
I dont see how a motor with same displacement as the other will make much more more torque!!!
Even on M5 my motor produce 270whp and 186ft/lb I dint see a 2.1L making even close to 200ft/lb
Even on K24 motors they need a lot of boltons an tuning to produce 200ft/lb on stock block setups 99x87

Still talking turbo in the non-turbo section?

88x86mm motor. its simple and will make 250whp easy. this would also be my choice for a non sleeved n/a build.

can a VET gasket be used happily with 88mm pistons?

yep... a rebored vet hg

Cometic makes a 88mm bore .80mm thickness HG that works better
