I ended up getting a D15B7 as the swap engine. Of my choices of the D16y8 and the d15b7 with a 99 Y8 Vtec head, i went with the d15b7 becaues the y8 was in very crappy condition and was leaking oil and ****. So now i have this high compression bullshit. Which is terrible for my project since I want to go boost. I was wondering if Vitara pistons fit in that block or any other cheap pistons I can put in there to lower the compression so I can boost it. Because finding another engine is becoming a pain. I only want to hit 200WHP cuz its my daily driver. Any suggestions? Does anyone know if its possible?

Buy some 75.5 Vitaras & forged rods and you will be good to go.....you could run it as a standard mini-me but make sure you get a good tune.

are u sure i could boost @ all on a standard minime? the Compression ratio is like 10.3 or something according to honda compression calculator.

you wouldnt be able to run much boost on that compression and stock internals as for another motor come get this one i have

I suggest all forged internals, but the viatras long as they are dished ones and some forged rods would be better than none at all,, you could boost with out touching the engine at all,, but ur not going to run many lbs of boost maybe 4-6lbs looking at 160-180hp with out decreasing the life of ur motor quite a bit. Just do it right the first time,build it for boost. or your just going to be pulling it apart later doing the same thing you would be now
