Default Is this true???

Is it true that ls's handle turbo's better than GS-R's ?
WTF: this guy told me that and im trying to decide weither or not I believe the guy...

i believe its true, because the LS has a lower compression ratio

Easier to tune/install.

A GSR's compression is higher than an LS's, which techically makes it SAFER to boost. However, boosting at normal stock levels, differences in reliability between the two are negligible. Boosting at high levels also negates some of the reliability issues because most people boosting at high levels, swap the higher compression pistons out for lower ones anyway.

In most cases, they are the same in terms of reliability. I have worked with/driven many turbo LS's and GSR's. No problems with either.

At stock levels, a GSR boosting will make more power than the LS anyway.

You have to remember that high compression AND high boost is technically the best way. However, due to tuning issues and reliability issues, it isn't done very often because it isn't easy.

shamoo couldnt have said it any better. plus although the gsr has higher compression stock.. you also have to worry about the wimpy rods and other internal parts of the LS motor.. there are pros and cons to both but if i had to pick i would go GSR for the fact that you have the VTEC powerplant and alot more overall to work with

kinda they have a large margin for error over the gsr

yea since the ls and gsr internals are sooooooo different. we are talking maybe 1mm here ppl. The b18b is a better boost platform all around thanks to the crank, taller gears, lower compression and more low-end torque. Sure a VTEC motor will make more power on the dyno but did you ever take into consideration the torque curve? Its been proven over and over again that both of these motors can handle about the same power range on stock block which averages around 300whp. So basically the answer to your of is the LS motor better for boost is yes for several reasons. Leave the VTEC motors to the n/a junkies

EDIT: the only reason it takes the LS so much more to get there is because of that suffocating head.

taller gears are lame...unless you're after the gas mileage, but that in no way makes the LS BETTER for turbo...

um yes it does...ask anyone with a boosted car and they will tell you the longer gears help you hold out the power in each gear longer. If your gears were super short all the time you would have a hard time taking advantage of boost.

it's all in what you want and what you used to build man...and YOU ask everyone...you'll see. It's not a matter of right or wrong here...you're stating your opinion...don't speak for others, I don't think they would appreciate it. I stick with what I said, having LONG gears does NOT make the LS better for turbo. You are talking about a trans, he is talking about a ENGINE.

whatever you say...im not stating my opinion. its just a fact that boost requires time to spool. but build whatever it is your heart desires.

it depends on what turbo you use as far as spool time, I'm not in to truck turbos, why would you use one that takes so much time to spool...I am refering to the normal t3/t4 setups...now, I'm not technical enough at this point to throw numbers at you, but I have friends that are turbo, and there is a SIGNIFICANT difference between their turbo's spool up on the same/similar setups. You do the same

1 fast DC2...the answer is LS-T...don't skimp on parts and you'll love it

correcto sir, your average t3/t4 setup has such good spool times long gears arent a mandatory thing. But when actually making big power it becomes a essential. We actually have alot of big par hondas in my area of town. For example here is a guy i go to school with. his old teg

when spooling something like that you need every bit of revving you can get. Another local turbo honda guy Big Jason is currently revving to 10k but hes making roughly 400hp. I guess our argument is useless since there are so many variables that apply but as far as making big par, long gears win. Small turbos like t3/t4's and gt28, stock gears are just fine.

True, but mechanical efficiency will surpass that any day. It is a VERY BIG misconception that longer gears are better for boost. Sure, you might be making boost for 10 seconds straight, and the GSR might be making it for 7 seconds, but in those 7 seconds, the GSR will already be surpassing you because of it's gearing. When it shifts, it's already at a higher RPM than you, and still at a higher mechanical advantage.

ls motors are cheaper than gsrs...so if you blow it up, its less money to get another...

and shorter gears are always better...no matter what car, turbo or na..but we shouldnt get into this as it becomes a pissing match...search and see this has been beaten to death....

VERY TRUE!

Many of us forgot this simple fact. For many of us, this simple fact makes the LS better in all situations.

With quality engine management and a damn good tuner, either motor is perfectly fine. The GSR motor will be more responsive than an LS motor making the same peak power, but again if price is an issue the LS is the way to go.

Regarding gearing, you will accelerate faster with a closer ratio gear set until you make enough power that the actual time it takes to shift is longer than the acceleration benefit of the shorter gear. No street driven Honda makes enough power for that to happen and if you ever do make that much power you won't want to be using an OEM tranny.
