2000 Civic Si Motor

everything i said with the LS/Vtec was correct. I did not say it was unreliable for various reasons. The only thing i said that if not built correctly it will not last. An Ls/vtec is not something that should be done by an inexperienced builder. As for turbo, no a turbo should not be used on a Stock block. The engines above have been sleeved most likely with dart or godzilla sleeves, they can withstand boost where as a stock block with high compression should not be boosted.

I hope you weren't refering to me because I never said anything about the r/s ratio having any type of correlation to the power output at high rpm. And another thing as I remember it we were comparing a B16 to a b18 a/b not a B18C like the ones you were talking about.

The only reason I mentioned the B18c was because someone asked about my gs-r with the B17, So I compared mine to a newer B18c powered gs-r, and said that my 2nd gen B17 powered gs-r is just as fast if not faster than most 3rd gen B18c powered gs-r's stock for stock. That is as far as I know the only reason B18c was ever mentioned in this thread.

Anyway As I have stated before I would go with a B16 over a B18 a/b, however if he had mentioned getting a B18c or even a B18c5 I would recomend one of those, He did not mention either of those two so given the choice of a B16 or a non-vtec ls engine my personal choice would be the sportier, more fun to drive, but not necasarily more powerful or faster B16.

Damn. And for the over a year I drove my stock block LS at 300 WHP I thought they were a decent motor to turbo. I guess I was wrong

Did you read the whole thread I said LS/Vtec stock was not a good engine to turbo because of the high C/R. I DID NOT SAY THE B18 as an engine was bad to turbo. Read the whole thread b4 you decide to be an ass. i was assuming everyone knew i was talking about an LS/VTEC.

I hope you didnt mean me. I was refering to a stock motor with a better r/s ratio can rev more safely and put less stress on the cyl. walls. Looking at those dyno graphs, that motor was far from stock!

Yeah man, 9.6:1 or 9.7:1, that is insane. Ignoring the fact that CP makes a 9.8:1 turbo piston, and my new turbo shortblock is 10:1 CR, there is no way you can run that high of compression with a turbo!

Not an awful lot. A sleeved motor with some good (pauter, crower, etc) rods, a good flowing head, a big intake manifold, big cams, and a big turbo. You don't need to do anything earth shattering, or anything you can't get basically off the shelf.

Bump too, because I want to know what slow integra has to say about the inability to run high compression turbo setups

YEAH, 800 whp is like 250 more then i have ever heard of! I would love to see a video of that beast getting dynoed!

[Si Integra]

dynoed...lmao, i would love to see a video of that thing getting traction.

The bottom line is this. B16's are different. You are comparing apples and oranges. B18b is a lower reving higher tq motor, where is the b16 was designed to rev higher and have more hp.

I guess the best way to sum it up is this, I don't remember where or who from I read it but it is a great way to put it:
"Torque wins races, HP wins shows" If boosting the car, either will be fun.
I personally would match the b18b with an LS tranny but what the hell do I know
