LS or GSR?
I'm thinking about buying an Integra to turbo it but am not sure which I should start out with. GSR has more power to start, but with the higher compression and addition of VTEC might not be as smart as the LS (which might have a better tranny??)
If you had the choice between the two, for relatively same price, which would you go for?

Well if they are pretty much the same price I'd go w/ the GSR, if you can get an LS a decnet amount cheaper I'd go that route and sink the saved money into rebuilding the engine!!

LS because the block has a higher bore, lower compression and the tranny has longer gearing. You can always add a VTEC head later, or a B20 bottom end. and LS is cheaper.

I agree, go with the LS, turbo the hell out of it, then build the bottom end for more boost. That would be one mean machine 
Then if you want go vtec with it to.

Re: LS or GSR? (90_Civic_Hatch)
whoa whoa whoa, LS has longer bore? LS and GS-R bores are identical, both measuring 81mm across, the LS has a longer stroke-- 89mm, GS-R is 87.5mm. I could get into talking about the LS having a greater side-load than the GS-R, but that's another story. Do you mean B20B/Z shortblock instead of the LS??? The B20B/Z Pistons (84mm) won't fit in any other B-series motor, the rest are 81mm, except for the B21A1, out of those 90-91 2.0si Preludes, which are oddly 83mm....
If you plan on driving it hard, get the LS-- they're A LOT cheaper to replace blocks, etc... But who wouldn't plan on driving it hard, you're turboing it for a reason, right? Go LS, it's more cost-effective. If you have ***** later, build a GS-R motor.
If it were me, I'd just get a '92+ Civic (non-4dr), buy a B20B/Z, and turbo that. Hey, gotta be different, right? If worse comes to worst, just use a LS block to replace the screwed up CR-V.
