the b16 head flows better than a gsr, but if you are going to do head work its a useless point, after a port polish etc they will flow the same ...
the b16 head does flow better than the gsr head, but the gsr head yields a higher compression than the b16, so if u take an ls block and put the gsr head on you will make more power: fact.

alex, dont buy a b18a1 block. my friend has had like 3 of those, they are super old and beat up and u can get it much cheaper than 350, me and my friend pulled a b18a1 out of an integra and sold it for 200 they arent worth more than that. plus wen ppl see you have a b18a1 block its just like..idk..i just dont like how it comes from the second gen integras..b18b1 for the win

Ok, yeah I can pull a B18a block from Pick N Pull, but who knows the condition of the motor. The motor I'm buying only has 180,000kms, which is pretty low. It's passed air care for the past 8 years flawlessly, and it has perfect compression across the board. It's a complete longblock too, not just the block. Good deal in my eyes.

So a 1993 b18a1 is a whole lot different than a 1994 b18b1, doesn't make much sense to me. They are the same damn motor. No differences between a 1992 or a 1995 motor b/c they are all obd1 and have the same mechanical parts. $350 is reasonable but not the cheapest you can get it. Usually I can get one for $100 usd, but you have to think that the man is speaking in canadian $$$, which is less than the american dollar. He's rebuilding it anyways, what the hell does it matter?

What year is the motor, 90-91, or a 92-93 b18a1?
It's from a 90 integra. I'm not rebuilding it. I plan on boosting it on stock internals. Then maybe after some time I'll put a vtec head on it. I'm sure the motor still has lots of life on it, it's only got 180,000kms and they can hit 300,000kms easy. Motor should be here in a couple hours, I'll post some pictures.

I'd go around it and put on new front and rear main seals b/c of the age, and change to some newer cams b/c you have the "gay" cams in that motor, also, you will need the obd1 distributor, alternator, and injectors. but a must for an older engine is seals, just to eliminate headaches like the rear main leaking oil a couple of thousand miles after you get it in.

Ok sounds good. My friend says he can hot tank my motor for free if I want. But thing is, then do I need to completely strip all the internals out and replace all the bearings, seals, gaskets when it goes back together? I want a clean look, but not at a huge cost when I'd be replacing a bunch of stuff. What do you think?

Don't worry about hot tanking it if you aren't rebuilding it.
Yeah, I decided on that as well. I'm going to get an engine stand then I can scrub it up with some degreaser. After I get the grease and dirt off, I don't think the block is going to be too shiny, is there any product you've used that shines it up nice without actually painting it?

no, its just a rough cast aluminum at its cleanest b/c I did it to mine and just a flat gray looking color.

So only hot tanking gives you that shiny cast iron look? Aww oh well I guess I'll have to live with, dull cast iron, hehe.

ive had both a ls and a b16 in my crx with the same stage 3 clutch and flywheel exaust etc.. the b16 walks on the ls all day

but i thought tq wins races?:hithead:

torque is useless without rpm's which is why the ls loses every time. the b16 makes less peak tq but makes better use of it with rpms which is everything when it comes to racing. and when coupled with a shorter transmission that better suites the higher rpms, it actually puts down roughly what the ls puts down tq wise to the wheels. i dont mean dyno numbers where its calculated but actual tq to the ground.

That's due more to gearing than the actual engine. Put that tranny on an ls and race again.

of course its due to gearing, thats why the higher rev limits of the vtec motors help out. you can use shorter gearing as a multiplier, without sacrificing top speed in each gear.

i know this is kinda late but the b16 head is compared to the itr head, sure you can take the itr internal components and its better then the b16 but iam talking flow and such. Thats why when you use a gsr block with a b16 head they call it a poor man's type R. just putting some .02 in
