Hey, I was wondering what would be the pros and cons of having an LS w/ Turbo? I was thinking of doing this in the near future, but now i'm having second thoughts cuz I was told that i'd have reliability issues and such... I was thinking between just LS, or LS and turbo, or B16a... I'd love to hear that whine from the turbo in my car, but I don't wanna have to put up with mechanical probs a lot...

AND, if it did come down to just goin without the turbo, which would be better to swap in an EF hatch... a B16 or non-vtec b18?

Thanks

If you want to do turbo

B20 has a fond place in my heart.

I've seen Turbo'd B18B school Twin Turbo Rx-7s

Out of those combinations you listed, for the greatest power.

B18B Turbo all the way.

Reliability has alot to do on how clean your install is.

If you're doing non-turbo for an EF hatch?

B18B all the way, easier swap and fast.
You'll run 14s all day long...

PLUS you can always turbo down the road

If you're not going the turbo route, I would recommend one of the DOHC VTEC motors. They will make more power than the non-VTEC motors, and valvetrain parts are easier to find and more readily available.

i "heard" VTEC and turbo are not a good combination, i could be wrong though but nottice the quotes.

imported_SW20 MR2

It works just fine.

hmm, i guess it was a myth than, thanks for not flaming though

It's a actually better to turbo a DOHC non vtec because of it's lower compression than DOHC VTEC motors.

Anyway as you were saying you have an EF, don't bother with a b18b, it's not a straight drop in, go with a b18a1 or a zc motor and turbo it.

It comes down to two things, allmotor or turbo?

turbo will make more power for a slightly higher cost considering you run 6psi only where internal work on the motor is not needed.

The turbo setup will be reliable as long as you give it the care that it needs. My suggestion is find yourself a cheap ZC motor and turbo it and you can welcome yourself to 13 second quarter mile passes, if you are not sure then get a 1st gen b16a motor and build up a nice all motor setup.

yeah i heard something like that, i just don't remeber what it was about the vtec and non-vtec motors. so it wouldn't be recommanded to turbo a b16 huh

what kind of stuff would someone have to do to make a car all motor.

imported_SW20 MR2

Turboing a B16A is fine. It's been done many times in the past with great success. For FI setups on stock bottem ends, it is ALL in the tuning. Period.

For a nice allmotor car, you should do high compression pistons, rods, cams, and headword. Those are the main components.

imported_nautica_t

cool
thanks man..

Sadatay

so would it be more feasible to just make an all motor, or would all the internal work even the costs of having a well done turbo?

imported_SW20 MR2

It is expensive regardless of what you do. Tell me how much you have/want to spend, and I can make a suggestion.

Sadatay

Ok, so how much am I looking at roughly to do a non-vtec b18 swap, compared to a b16 or vice-versa? I was quoted about $3500 for the b16 full swap, but what about the b18? I was hoping that if the b18 is much cheaper, I could save the extra cash and invest in a turbo down the line. I'm hoping to spend no more than $5000-6000 for all engine work (already including the swap), whether it's turbo or all-motor. So what would be best with that kind of budget?

imported_SW20 MR2

I'm not sure on the cost of a B18B swap, but it will definitely be cheaper than a B16A. If you are going to do a turbo setup, I would budget no less than $6-7k for the turbo system alone (unless you can do stuff like make a manifold, piping, etc. by yourself). You can do a really ghetto turbo setup for cheap, but I don't believe in those.

On your budget, I'd say you should probably go the NA route. You can get the B16A swap, and then do some work on the head. You can get a nice set of cams and some headwork with the money you have left.

Sadatay

Cool, thanks for all the info and advice... Well i might still be able to stick with the turbo setup in the future, i mean, my budget is not dead set on those figures, so who knows... I'm just trying to keep at it a moderate cost... but i'm like split down the middle right now choosing between which type of setup i wanna do... Either way, the results should be great...
