I'm thinking of getting an Integra, and I was wondering which model is easier to turbo. Should I get the LS or go spend the extra cash for the GS-R, both of them '95. Just need peoples opinions on which engine is more flexible and if the extra cash is worth it for the VTEC.

 

Hell yes the extra cash is worth it man!!!!!!!!!!!

 

Boost + vtec > boost

Shell out the extra money for the GSR, you will be glad you did.

 

the extra time/money is worth getting a gsr

 

yep, I've owned an ls / gsr, The gsr is hands down alot more fun.

 

gsr pwns ls
although i have heard good things about boosted LSs. However the extra HP with a gsr engine - i think is worth the dollar.

 

just do the ls/vtec head swap.

 

Why? So you can have an unreliable, low revving GSR motor? With the amount of money involved in properly building up an LS/VTEC conversion, you might as well shell out the money for the GSR.

 

A stock GSR head is going to flow better than a stock RS/LS/GS head.
The GSR has a higher redline than the RS/LS/GS motor.

Both of these factors combine to make the GSR more efficient than the non-VTEC motors at a fixed boost level.

So if all you plan to do is build a decent streetable setup without going inside the motor.. go with the GSR.

But if you plan on tearing down the motor to build for a high-boost (12 psi+) build..then an non-VTEC Integra will do fine. The money saved by going with a DC4 can go into headwork and cams that will address the inefficiencies of the stock LS head.
