I was thinking about boosting a b16a1 or doing a frankenstein. Anyone put a b16a1 head on a b20 block? What is all involved? Would a lightly boosted b16a be faster?

 

i havent done one but i suggest boost the b16a. if you go b20 with a b16 head youll need a different tranny for best results. something with taller gears, like an ls tranny. also dont forget about the weight.

 

The b16 is such a better motor. The B20s cylender walls are so thin, u gotta be real careful.

 

Please don't do it. For the love of Honda engines everywhere.

 

Thanks for the advice. I'll boost the B!

 

i have a b16/b20 engine. the cylinders walls are fine to 300 horse if tuned correctly. the b20 will supply more torque and more potential than a b16. it's a powerful engine. it's a toss up really either way you go. the b20 requires a plug in a hole on the head deck surface and a oil line from the block to the head. you also need a b18/b20 timing belt, head gasket and, the head or block machined for dowl pins. Golden Eagle make dowels pins that fit with no maching to either part, i suggest these. if your options are turbo a stock b16 or build a b20vtec i would turbo the b16 if you plan to stop there. if you want to hit 300+ whp go with a 2 liter.

 

Yeah, so are D15B1s... you can say that about anything. But not for boost. If you're pushing anywhere near 250+ whp for more than a month with no problems and can show me a dyno sheet to back it up, I'll believe you. But I'm not talking out of my *** when I say that they have a lot of problems.


More torque... yes
More potential... no way in hell. Not without a full internal rebuild.

 

i agree. pushing 250+ is not healthy on either a stock b16 or a b20vtec.. but a b20 will hit nearly 200 whp na with a a better powerband for less than a turbo b16. what do you expect to spend on a b16 turbo set-up? 2500 to get in the door? what power would you run on a stock block b16? if you're in the same position and have a b16 in the car already you can spend 2g and have a powerful na 2ltr. 1g to get it in. 1 g on forged pistons and management,+. you can make 150 tq across the board with a high comp b20 and peak hp at 200 wheel. turbo the b16 and you're deeper into the money.. and when you hit 250 wheel in the b16T you're in the same situation as the b20 just a few mm shorter on the deck height.

 

That may be true, but it won't hold the power as well. And I'm still curious how you plan to get a stock B20 to 200whp without upping the displacement or doing a headswap.

I'll give you the benefit of the doubt since you're obviously new to this game. First off, you're much better off piecing together your own kit, which shouldn't cost more than $1,200. After that, it's an open door. You could go for some GSR pistons to take you down to about 9:1 CR, then crank up the boost. Or you could up the displacement to handle more boost and help your torque numbers. Type R exhaust cam and TB are obvious choices. The B20 may have you off the line (for a second or so) but after that, it's turbo territory.

 

assuming the guy has a b16 engine i've priced out a nice b20 engine with power in the 150tq/200whp range.

please.. price out a similiar b16 turbo engine for $1200.
