ok here the deal im still new to this i just got a 92 da. the guy i got it from said that the block is 20 over bored or something like that. so i guess he has a built block. he said his head was bad so i decied i wanted to go Ls Vtec so i found a 98 spec gsr head with type r internal the head has port and polish i was just wondering how much horsepower ill be making with it sitting like that hope i explain it well to where u understand what im doing i still need to look for a manfold for it and a ecu

 

You never know the only way to really find out is to get it dynoed

 

theres a huge ls/vtec install thread done by bambam, I'm sure he can give you a rough estimate.

 

dyno it, do ur homework n get the rite stuff i ur rver to build it (etc. gsr head studs, lsv kit, n all the gsr/typer goodies u need)
