Ls Turbo?
well... lets put it this way. both motors are great to turbo... BUT out of both motors... the LS is safer to boost stock because of the lower compression. LS turbos kick ***... even without vtec.
It depends on how much money you got. You can make either engine safe, but as a beginning, I would do the LS motor. It is cheaper.
If you got a lot of money you can make either SICK!

ls/vtec with a turbo and built bottom end is sick, but starting off with just a LS engine and putting on a turbo is cheaper than putting one on a vtec engine only cause you have to make more mods to be able to boost a vtec engine at the same level as a Ls.
You would be surprised of a potential of an ls. Everybody says vtec this and vtec that, ask any of the pro's most dont even use vtec technology. Boost is boost, but there are "tricks" you have to do to the motor to be fast out there.

you can run like 3s maybe low 4s with a turbo on an ls jp but in a civic hb ive seen/ heard of peeps runnin low 13s high 12s with a good driver and thats just a turbo on a stock ls no internals

The LS engine has slightly more displacement than a GS-R/Type-R, lower compression, and longer gears. I've heard that VTEC really doesn't make much of a difference with forced induction.
i just blew up my ls/vtec high compresion.....thats why im asking if i should build just a ls.....the vtec worked really good when i had it.....it was ls/vtec 10:1 with 9lbs....stupid oil pump gave...and i blew a hole in my block...but im gonna rebuild it....just thinking about making my grls car go fast.....ls turbo on a del sol? how fast u think that will be.....stock ls, greddy turbo kit....stock boost......how fast?
my LS teg turbo runs 12s w/ stock internals...
208whp/187 TRQ w/8 lbs of boost.

Gotta love the torque from the b18b. Too bad the head doesn't flow better or else it would be the perfect engine for boost. if you plan on sticking with an FMU/intank keep the boost around 7-8psi max, or else you will be replacing your rings lands after a year or so.

im thinkin high 12s right? with slicks? because i know 8lbs cant get you lower than high 12s.

yes... high 12s all day w/ slicks. 8X20X15 MT slicks

A properly ported LS head will flow better than a stock B16 head.... I can testify to that.
[quote]i'd go with ls turbo. i don't think it would be real fast if you are gonna use a greddy turbo for an ls. if you build you motor you should get a better turbo.[quote]
True, the greddy runs outta steam at about 10-12 psi, if you have built internals... the greddy will limit you severely... you'd prolly get more power at lower boost from a larger turbo.
[quote]What are some of the other mods you can do to an LS Turbo to make it faster? Safer?[quote]
Complete engine management system and tuning (Hondata,DFI, Haltech, AEM EMS...etc...) and fuel parts... injectors, pump
The reason many people say the LS is better for boost is because it comes with lower comp pistons... the pistons are not ideal for boost as they are cast aluminum and WEAK. The LS rod stroke ratio is not exactly idea for higher revs, so boosted duty is great... when you have boost, who needs revs ? Heh heh...
The weakness of the LS is the intake manifold, it doesn't flow well enough... while this doesn't cripple the car's performance, it would show great gains in a turbo LS to upgrade it. But overall... turbo LS is great... basically you should just put on some type of engine management (at least an AFC) and the car should run well as a daily driver at about 6-8 psi, tuned well. But when boost hits... it'll pull like a bat outta hell.
Oh, BTW... what does 'stock boost' mean ? What's preset on the greddy kit ? That's what ? 6.5 psi ?

yeah but if you put in better pistons and a better intake mani then there is no weakness. if you're boosting a stock ls, yeah there are weakness's like every other. but if its built right not many weakness's except for the driver.

How in the world do you run 12's in an LS turbo ... in an integra (granted it's somewhat light) and 208 whp ?? At 8psi, 208 sounds about right on stock internals... but I would like to know how in the world you manage to run a 12, even a high 12 ? What's your 60 ft time and trap speed on slicks ?
here's the time: 12.8@107mph
60 foot... 1.8
slicks: MT 20X8X15 on 95 gsr rims
car weight: 2325 w/o driver -JDM front end, cf hood, strip interior
Dyno: 208whp / 187 Torque
Dyno at Importbuilders by JEFF
Motorsetup:
B18b LS..
Drag turbo kit, 310 injector, aem fuel rail, S-afc, skunk sprockets, 4 puck clutch w/lighten flywheel, MSD ignition, ; the motor was stock:stock internal, stock T.B., stock intake manifold, stock cams. Redline at 6900rpm
I dont' care if you don't believe me...
and there are NO need to lie about running 12s

So basically, you are running a Drag kit at 8psi on a stock B18b ? With stock redline.... And you're doing high 12's in a 2300 lbs Integra ? That's alot of weight to drop.... and the numbers still don't look right... but O.K. I'll buy that today.... Good job.
"310 injector, aem fuel rail, S-afc" -
Do these parts just ease the flow of fuel? I have seen better numbers on cars without these items...
Just wondering...
12,s are just crazy - good job!
