EDIT:

I have a crv motor with some bottom end issues so i need to rebuild the bottom end. and i want to build for boost. but not too much boost.

i've done lots of searching and no one has seemed to have built a non vtec crv motor.
regardless i have to rebuild the bottom end so i may as well put aftermarket parts and do it right. can i save money on the head with low boost?
how much boost can a stock head handle? crv's redline are very low. i forgot exactly how much, but this is a daily driver so this motor will be more fun in a hatch. but i want boost as well! low boost for my first turbo setup.

also what parts are needed for this motor to be put into a 92 civic. bseries civic/teg tranny they bolt right on? also intake manifold, can u put integra manifolds onto the b20 head? does the hood close without cutting/knotching?

thanks all

should this be in FI thread forum instead?

no one builds non vtec hondas? not worth it? heres a thought. build the bottom block and leave the head as is and boost low boost? saves me alot of money on valve train and if i'm not making that much power i can save on a few more parts maby. i have no clue how much power i can make though. 10, 15lbs of boost? would i need to worry about floating valves at 15psi? yes sorry i'm a noob.

the issues you will encounter with the thin cylinder walls are the same that people encounter when building a b20/vtec. You should read those threads, since the basics are the same

not gonna be as worried about the bottom end since i will be building it properly. i will put money into the bottom, its the head i want to save money on. stock head :D low redline.

unless you sleeve the block, you are going to be limmited by the strength of the stock sleeves. They are very thin, and will not hold alot of power. I dont care what pistons/rods/bearings etc you put into the block, the sleeves are going to be your issue for high rpm and or big power. You could most likely boost 8psi on the stock engine (the b20 with the low compression from the factory, I forget which one that is), and be fine, or you could dump a ton of money into building the block, and still only be able to make low boost power because of the sleeves.

If you want to use an engine that is cheap for boost, build up a b18 ls block and head, since that is alot stronger, and you will more then make up for the missing displacement with the larger amount of boost you can run...

*edit* I see you have a b20 already... I would recomend just a mild rebuild with low compression and running like 8psi, 10 max and enjoying it... Or selling to me me so I can build a N/A monster with it...

If u can find a ls block i dont mind trading with u. but i am planning on sleeving the block since the block was so cheap. with a built block if i ever decide that i want more power i can just rebuild the head. i'm not thinking about that right now tho. i think with a built block it'll be a crazy learning experience for me already.

bump for swapping intake manifold sensors from crv to an 1.8 LS manifold? anyone know? obd1
