name of 94 civic stock engine??

[Mr. Civic]

so my best bet for my 94 civic ex is to swap it out for a b18b to turbo it?
And wat do u guys think about building a custom turbo?

[GScivic7]

custom is the only way to go

[CivicSpoon]

[Mr. Civic]

did u guys do that?

[GScivic7]

I did it for a friend, was going to do custom turbo, but I got a new car instead.

[Mr. Civic]

is it cheaper to build a custom turbo or buy it complete

[CivicSpoon]

My buddy did it and it was a lot cheaper than buying a kit (and it was hard to find a full kit for an h22a civic).

[GScivic7]

it is a lot cheaper and you don't get any of teh crap parts that come with most kits.

[94SolGrl]

^^ and YOU, sir, need to untwist your panties... Sorry... made a mistake... was tired... get off it.

[GScivic7]

was I wrong? No.

[94SolGrl]

No, you weren't... I made a mistake and you jumped my ass.... hence the reason you need to untwist 'em. Do I claim perfection? Nope. Do I try for it? Yep. Do I mess up on the way? Yep. There's a reason I'm a sol mod... as far as sols go, I know just about everything there is to know about them. I'm not a turbo ho... my mistake for inaccurate numbers. Both of the sols I had were N/A, built motors.

How can you be a mod if you dont have your facts straight and teach the newbies false info. I still am kind of a noob and I'm 15 and not so experience with engines but 16:1 compression is way out there. You should know better.


BTW, sorry if you had a typo.

Don't get offended....Veryone makes mistakes and I am not trying to be rude, but more make sure that people who read this know the correct information.

16:1, That is dead wrong. Even a race car on race gas would have issues with a c/r that high. The most you can run on street gas if tuned well is 12:1 or so.

the USDM B18B1 has a 9.2:1 compersiion ratio. A B20 has a 8.8:1 c/r (but can handle less boost due to weaker sleeves. A B20 is essentially a bored out LS block). A B18C1 has a 10.0:1 c/r. A USDM B16A has a 10.2:1 c/r. A jdm B16A has a 10.4:1 c/r. Both types of JDM B18C's (the Type-R and the SiR) have a 10.6:1 c/r, the B16B has a 10.6:1 c/r also...that is the HIGHEST compression ratio that ANY B-SERIES MOTOR HAS.

Now most stock turbo'd cars (like the WRX for example, and SR20Det, etc) hang around a 8.5:1 or 8.8:1 compression ratio.

The B20 DOES have a lower c/r than the B18B1, true. However, a B20 block is basicaly a bored out B18B1 block. It has thinner cylinder sleeves.

Anyways, as I said, not trying to be an ass, just trying to make sure the correct info is out there. If someone had read that, and went out and turbo'd a motor built to 12:1 c/r, they'd have a massive engine failure to put it mildly.

hmm...i was thinking bout doing a b18c1 swap then turbo it.....but from reading what you guys been posting, b18b1 looks like what i should be doing.

not just thinner sleeves, but they are 1 piece. Prone to getting hot spots.
