GSR vs. LS vtech < whats the difference?

...you need to know that gsr's aren't exactly fast to begin with.

So what is the big hype about GSR's anyways. I know I bought one but it was just by chance that it's a GSR and I bought it. I didn't set out looking for one, just wanted a clean Integra. Actually I started out looking for a CRX.
Anyways, whats so special about them. I don't see a huge difference between the LS and GSR anyways. Maybe I am missing it.
Teach me.. :D

I understand from reading this thread that the LS has more low end torque and even more compression I believe. To me, I would think that would make the LS motor better for DD unless it was boosted. Maybe if gas goes back down i will boost my Integra cause my love is Turbo'd cars but for now, the more mileage I can get the better. :yes:

no, the LS has lower compression (mid 9-s vs. high 10-s for the gsr) and no vtec aka no high revs.

the LS is a fantastic engine for a turbo car due to the lower compression and easier tuning, with a little more torque.

the GSR is even better as a boosted engine due to the oil squirters keeping the pistons slightly coolerm the better breathing of a vtec head, higher compression means less boost per hp.

ls vtec isn't bad my buddy made 391 whp @15-16 psi on pump gas with a mildly built ls/vtec. you just might as well go forged internals and some other beefy good stuff while you're building it.

Yea, that is how I built my Conquest Tsi motor. Weisco Forged 8:1 pistons, Race Prep rods, hopefully it will be a strong bottom end. No top end work other than all new parts but eventually I might up the boost.

ok, that means you have an LS/VTEC. Very common swap. What's the head stamp say?

ooh ooh i know! P72 cause they spun a rod bearing due to oil starvation on the GSR bottom end!!!!



lol i guess anyways.

thats what i was thinking, but it could have been a theft recover with no motor, or he wanted a poor mans arrrr and sold the gsr

One thing is for certain that the Ls/Vtec has a long stroke than a stock GSR.

Another fact is that the stock Ls/Vtec (stock ls bottom end with stick GSR head) will make more hp than a stock gsr.

Now, of course, the main variable will be the build quality, so we could say that more often than not, a gsr will be more reliable than a Ls/Vtec, especially in the high RPMs which honda's have been known to make substantial power.

So, with the original question answered above, the nexxt question is undoubtably somewhere along the lines of this:

"Which setup will make the most power, the cheapest way, while maintaining reliability?" :no:

...exhibit "A":yes:

Fast + Realiable = Expensive
Fast + Cheap = Not Reliable
Cheap + Reliable = Slow... eerrr something like that. :screwy: ... don't quote me.

The moral of the story, kiddies, is this:

With the right amount of money, you can make power with almost anything.
The reason that the LS/Vtec was created wasn't because some honda owner sat down 13 years ago and worked out the schematics of an LS motor and concluded that they would have an increased displacement over a GSR by 1.97% by using a GSR head on a B18B block...:thinking:

It was more along the lines of this...:

"Damnn Dude, I'm broke as helll, but I wanna faster motor. Sheit... I got this GSR head laying around, and I head that if you throw in on my ls it'll be quick."

...and VUWALA! The poor-man's-GSR was born.:D

So, if yoru like me, and you don't have deep pockets, and you wanna your civc or integra to keep up... Go for the ls/vtec. But beware... budget builds aren't garunteed for anything...

just my :2cents:

Where's that badge located? Don't ever remember seeing that one.

So assuming I have a LS head on my LS B18B1 block now, I could potentially swap the LS head with the GSR head and get some decent power for my DD?
That would be sweet. I don't like to reve in the higher RPMs anyways. So doing the swap should be pretty reliable as long as I don't peg it at 9krpms, right?

Head Stamp says PR4-2.. What is that? Is it the LS Head? Isn't the GSR head P72?
