i got a crx si a few days ago n have plans on swappin a motor in.. i plan on turboing whtaever it is but i want to keep the price down, so i was thinking homemade turbo on either an z6/y8, d15b (vti), or take the ls outta my hatch n turbo it when i sell it. more likely is the d series. i hear the d15b is better than the z6 and y8...more hp and higher reving? is this true?.... either that or ima get a dohc zc n turbo that...but i only wanna spend around 600 for a motor. also could i attach my SI tranny to the d15b or ex motor????

 

You can use your trans on any 88+ D-series, except those new backwards-spinning D17's... well, you can probably use it on those too, except you'd have 5 reverse speeds and one really short forward gear. :chuckles:

The D15B is rated higher, but if you put it on a dyno I doubt it would produce more power then a Z6 or Y8. They have a similar redline.

When you turbo, you want the highest displacement you can get. That's not something the D15B has to offer.

What's wrong with the D16A6 already in it?

 

hey thanks..i bought the car n the guy said ti had a 'blown headgastket'..'smoke was comin out from the head'...cause it supposedly stopped running on the highway. iduno though i havent checked it out yet..its gonna be a winter project thing, i already got another project going..but yeah ill prob get that motor runnin and turbo it..and run the shit out of it, then get a zc or something, with turbo..lower compression is better? what motor runnin stock internals at under 10 psi would be best for turbo..?
