i am going to be getting a late model LS or GSR(probably 99-01). a couple of my buddies have a LS and a GSR. i've riddin in both and the LS seems to have better torque and the GSR seems to have the vtec topend.

so the debate is on either getting the GSR or getting an LS and converting it to LS/vtec to get the best of both. i figure id save the extra money from the GSR and spend it to make an LS/vtec. so what is all involved in doing the head swap and how does the LS/vtec compare to the GSR?
thanks

 

Get the GSR....to do the head swap, I'm pretty sure you'll need the vtec computer and harness.

 

why the gsr? isnt ls/vtec faster?

 

dude, LS/Vtec motors can be rough on the reliability end...almost to the point where its not worth it unless your doing a full build.

 

exactly, go with the GSR

 

what if i was planning on fully building it

 

Then still get the GsR. It feels like the GsR gets out pulled in the lowend by the LS, but it doesn't by much, and any that does could be negated by a good launch (GsR vs GS), if you were to race them side by side you'd see that almost from the get go the GsR walks the LS integra. I built up an LsVtec, and am telling you, buy a GsR.

 

whats better if i was gonna go built w/ turbo. LS or GSR?

 

The GSR has more torque than the LS, it just comes on at a higher RPM.


For turbo, I'd stick with LS just to save money.

 

A built GSR motor is fully capable of making plenty of power--the extra tiny bit of stroke that you get out of the LS bottom end doesn't really net you much of a gain in the end. Besides, you can punch a GSR motor out to 2 liters by having it resleeved and bored out to 85 mm from the stock 81.

This is a very general question with no really good answer. Instead think about how much power you want to make and how much money you want to spend to make that power. Personally I would buy the GSR because you'll drive around with the nicer motor to start with, and usually these supposed project ideas take longer to get off the ground than anticipated.
