going to rebuild my 99 b18c1 motor I got some extra money to spend. I have not heard about how well the crvtec is doing with boost. It seems that it would be awsome(crvtec.com) but i thought i would ask you guys for some advice so please any help would be great. Should i look for the crv block? I'm planing on daily driver with lots of boost, also planing on building the block strong to handle 20psi easily.

i like the fact that the crv sleeves are thick as ***** but have heard that it should not be revved as high as b18c1 blocks -thanks for any help

 

Why do you want to do a CRVTEC ? displacement, rod to stroke ratio, toruqe ?

no matter how thick a CRV sleeves are, it will not handle a lot of boost like you want to ~20psi..unless you have a perfect standalone and a forged piston and rods

if all you're looking is displacement, then stick with B18C or B18B, sleeve it then bored it out to 84.5mm to make it a 2.0L it will handle a lot more boost and safer than a stock CRV block

and the reason why crv can;t be revved as much as the B18c is because the head can only handle so much..if you put a GS-R head on a CRV block, you can safely revv it to 8000 rpm, granted your ecu is also modify to do so...

good luck

 

I was in the same boat as you. What I decided on was to resleeve my B18c block to 84.5mm. You give up a little displacement (1956cc), but gain a better crank, rodo ratio, oem oil cooler, piston oil squirters, and a OEM crank girdle. Just my opinion.

 

On the other hand if a CRVTEC is built right it will rev fine.The crank needs to be balanced, the rods need to be changed, the crank brace needs to be installed, oil cooler and squirters are a plus. Mine revs to 9K no probs, it doesn't make power up there but RPMs are to worries. As for boost, I wouldn't go more than 15psi on a stock block, tuning is very important either way.

 

Forget the B20 and sleeve/bore a B18. I've been there and would not do the B20 again. Also, if you live in a smog restricted state, it is much easier having your original engine to pass the test.

 

Just turbo a LS

 

I was originally going to turbo a B20vtec also, but, I realized that the crank in the B20 isn't a good idea. If you plan on doing this, you should find a B17A crank.

Don't believe everything you read about B20 turbo's in magazine's. Its not as easy as they make it sound.

 

A B18C1'll perform just as well as a B20vtec when bored out and modded similarly.
