I thought the stroker kit only bumped the displacement up to 2.2 liters? Unless your talking about stroking the KA, then I could see where you were coming from.

I'm talking about a custom SR26DET setup ...

Then sell the SR22DET stroker kits

The KA cyclider (sp?) walls are too thin to stroke it to a 2.6 without a dangar of blown up ... 2.5 is good.
Or better yet, destroke the KA to 2.2 .. that would be nice

WRONG WRONG WRONG!...with a metal headgasket (1.2mm), T3/T04e at 18psi, skyline FP, 555cc injectors, Nismo clutch, 3" turbo-back exhaust === 425 hp (on an S14 SR20) you dont need to work on the bottom end of an SR until you start thinking of going over 450hp...the block can handle about 25 psi, before you start to break stuff...the H/G is the only weak point on the SR20..change that, and you can boost all you want...the numbers above were taken from my mechanic who owns a 95 240sx and did the S14 swap with those mods shown...he dynoed at 424.9 hp at the rear wheels in October. nuff said.

sorry, I dont see how you can get a 2 litre engine to 2.6, considering that the maximum stroking length is 92.6... I think... and I doubt you can overbore it more than 3 mm, even with resleeving...

the thing that makes the 240SX so fast at 300 horsepower is the fact that it weighs 2700 pounds + driver. Supra weighs in at like 3500 + driver with stock 320 horses ( I know they go way faster ). My 240SX weighs about 2550 right now, when I put in the SR ( if I don't go RB25 ) then it will lose another 100 pounds. Thats what makes 300 horsepower in a 240SX so fast.
