I've got a 00 si and a 91 teg rs. i want a turbo...for either or. If I turbo the teg I'd completely rebuild the engine, well I'd rebuild either. The reason I ask is because on other forums, I've heard that boosting a non-vtec engine is better. I don't know why, but that's where you guys come in

I dont know what to tell you, but can say the boosted b16 is a good choice.
I have a built ls/vtec b18a block/b16a2 head
my boy's b16 block built with the same internals as me running the same turbo, on the same program tuned by the same person, and he used to murder me all the time, I can honestly say he is the only car ever beaten me in all my races. but I was running gsr cams while he was running skunk 2 cams, then he switch to crower cams and I switch to skunk2 and he was still wooping me. he will be on talking **** when he see this.
so the boosted b16 is a good choice.

i personally think b18 non vtec motors are a little bit friendlier with boost than b16's and tend to last a bit longer when pushed hard, mainly due to the lower compression IMO. it all comes down to personal preference. a b16 will make more horsepower with similar conditions compared to the LS motor, torque will vary tho

id personally choose the ls block with the b16 head if it were an option

the lower compression of an ls motor makes it more forgiving, in a sense it can take more adverse conditions and still be ok.


i think a nicely put together ls turbo will be fun as hell for around the street.
maybe a large t3, small t3t4 turbo and like 10psi boost. its gonna have one hell of a midrange/street powerband

Yeah I just saw the post on your B16 also, great numbers from a stock B16.

As you can see in the variety of opinions.. it's all in personal preference..

EFvtec Yo!

I'm in the progress of boosting a B16 right now. But i rode in my friends Boosted LS civic coupe and the torque from that LS on 10psi was amazing.

i love the torque from my LS. i may suck it up and by another b16 head and build one of those amazing ls/vtec setups lol then boost it. i think im a little scared of boost though bc i want it to be reliable. i may end up with a supercharger. lol i just wish i could test drive them and see which one i like better lol.

Despite that logic, it is somewhat flawed. Explaining it mechanically, the longer stroke of the LS (more torque) puts a hell of a lot of stress on the ringlands, much more than the b16 and you will more than likely crack those ringlands if you shoot around 300whp on the stock pistons (no matter how good your tune is). The B16 however will live above 300whp without a problem. So my vote, boost the SI, it's a much nicer, newer, more comfortable car

naturally yes of course the ls makes more torque, this is a boosted motor tho and extra compression that the b16 has naturally leaves a lot less room for error especially on the cast pistons. the major difference will be the powerband

i make almost 300HP on a stock b16


i love it. i plan to just build a high HP b16 and i think u wld enjoy it to.

'nuff said.

scB20teg

Yeah and the B16 has a much better powerband. The LS powerband looks like there is something wrong with the motor the way it drops off like a rock lol. Oh and please don't post dyno graphs of some freak LS motor that actually made power past like 5-6k lol. I know what they look like, might as well be a picture of poo.

I would just spend $500-$600 on a b16 head, and slap it on the ls, now you have an engine worth messing with. Ls/vtec turbo that's my vote
