Ls turbo Vs Gsr Turbo

[j0nbunklah0m]

So im thinking about gettin an Ls swap in the near future... and boosting it soon after that.. i was wondering if Ls turbo would make good power compared to a gsr turbo.. thanks in advance

[Vuongy_Dong]

gsr will make better power, and with the higher rpm band, its a better platform. LS is still a great motor to boost and daily drive.

Oh really, I just thought with my knowledge of Hondas that a LS turbo usually holds more HP and holds it better than the GSR motors. But either way, Pizza Boyle, you are still gonna lose to me. hahah

ls definitely does not hold more hp, or "hold better" than a gsr. stock ls turbo makes a great daily driver though. you will have fun with it. to keep it reliable, i suggest keeping it at about 250whp.

250 whp is alot to me.. didnt even think a stock ls could push so much :D.. but how much psi n what turbo should i usee?:???:

250 whp is alot to me.. didnt even think a stock ls could push so much :D.. but how much psi n what turbo should i usee?:???:i'd keep it around 10 psi or less. and with that hp i'd go with something like a t3/t4. it won't overpower it and spools quick. simple and affordable.

sweet. thanks for the info!! +1

[patrick4588]

a t3/t04e 57 trim will work well on a stock ls

[helcat17]

a good t3 does fine up to 240 hp allsoo just not much above that and spools fast i was geting full boost at around 2500 rpms on a garrett m11 t3

A couple of years back I built a LS turbo EG hatch. Car was a freaking rocket. After having done that, I am a huge LS-T fan. That motor was tough as hell and is STILL running to this day via Hondata road tune w/ a T3/T04e 60trim. Car went [email protected] with me on 10psi, I then sold it to my friend so I could buy an S2k, and he bumped the boost to 14.5psi and sprayed meth and went [email protected]. The lower compression of the LS motor allows what every turbo motor from the factory allows, a larger margin of safety. A good tune is key, but for a given setup, lower compression is always sought after when going with forced induction. Hence why most built B18C1's knock down the compression a good bit. BTW, the torque hit from a LS-T makes for the MOST fun street car out of any of the honda engines IMO. I was good friends with a guy who had a high [email protected] mph Integra with a built GSR motor and while it hauled ass, it just didn't "feel" that fast. Pleny of hp, just not as much tq. My LS-T hatch "felt" fast :). BTW, LS engines are also a dime a dozen so its a great way to have a cheap, fun, fast, and when tuned nicely, reliable DD.

[patrick4588]

im assuming your guys were on street tires running those times. 13.8 @ 111 is pretty horrible driving. street tires makes it a little better, but damn bro that should have been at least a 13.3-4. d16_turbo ran a 12.8 @ 108 on his stock ls turbo (57 trim) at only 8psi.

[1.8t]

The car still had the stock all season tires that were rated for 95mph on it ;). Pretty dangerous if you think about how fast we were going in the 1/4 in regards to what the tires were rated for, I never thought about that until after I sold it(kept the car looking completely stock for the sleeper effect)

Oh really.I hope you have information to back that up?

[Batlground]

depends what you want.

The GSR is better because:
Higher compression =more power with less boost
Stronger Ringlands
better geared transmission
8200rpm Redline
VTEC

The problem with the LS engines is that they have a long geared transmission and a low redline. The heads dont flow much past 350whp, ive seen maybe 2 or 3 guys locally make over 400whp with stock heads. a stock GSR head can handle 600whp no problem.

The LS wont make as much power all things being equal.

But, the LS is cheaper, has a longer stroke so generally more TQ compared to the GSR.

if your goals are 250whp an under, its fine

ahh.. thanks that clears alot up!! +1 :) -- i just have always heard from people that LS is better because of lower compression

[j0nbunklah0m]

ohh.. and another thing is my freind tells me that hondas are not very reliable once they are boosted?

[bRiAnMcIvIcS]

For that power range i would go with the garrett gt2860rs turbo. If you can save a lil more money than get the GSR its a better all around motor. Boosted Honda's can be very reliable if you do it RIGHT(quality parts and a tune).:goodjob:

[xdavidscenex]

stock ls motor are pushing over 400+whp now..check out honda-tech.

[Ronsam2006]

No I dont have any information to back that up as it is, I wasnt trying to prove anything in the first place. All I said was "I thought with my knowledge", which meant I was hoping for someone to chime in and donate some info. But I know I was wrong about the HP part, but I did think the lower compression of an LS helped keep it reliable.

Dont believe everything you read.

Theres guys claiming 600whp on stock b16s, doesnt mean its realistic or reliablestock LS engines can handle 250whp for maximum reliability, 300whp is pushing it

[bRiAnMcIvIcS]

Listen to Mike.

Thank you...

and after a few pulls their rods will exit the block...
