I'm planning in doing a e85 conversion for my b20b, it's a JDM high comp b20b with grs trans and torsen lsd. What I want to know if the stock sleeves would be able to hand this on pump e85 I know that pump e85 could handle the compression but would the stock sleeves? And, how big of injectors would I need? I'm thinking of doing h22a 1025cc e85 injectors. I also want to raise the rev limit to 8200 or 8400 rpm I'm not worried about valve float I have dual coil valve springs and good cams, I want to know if the block with stock sleeves with a block guard and girdle would be able to handle this? I DON'T WANT TO HEAR ANY "JUST TURBO IT IT'LL MA KE MORE POWER" I WANT AN NA 200WHP OR MORE B20.... When I turbo it I want a sleeved LS 84.5mm bore block with ported polished b16 head and VTech killer cams, 300whp.

NO to all your questions...

E85 will not give you more power, so sure, your stock sleeves can handle it. E85 is just a more knock-resistant fuel than pump gasoline, allowing you to more safely run higher compression or more boost. Please understand that to convert to E85 you'll need much more than larger injectors, including a tuning session.

With e85 you do make more power but the reason I want to upgrade to e85 is so that it will handle the high comp with vtech and higher rev limit and advancing timing without it knocking and blowing my engine. The b20 has weak sleeves and I don't want to crack a sleeve with the Increased cylender pressure and more power.

You don't want to hear people suggesting to you to turbocharged the swap, yet you say you're going to turbo it. Stop contradicting yourself dude. Not making any sense...

I don't want to turbo the b20b because it couldn't handle high comp, either and 18psi, when I turbo it I needs a fully built internals and sleeves then it can make the very conservative 300hp but I want a 200hp na very high comp NA B20B with e85.

making bullshit tech threads doesn't get you anywhere.
