I recently came across the option to get a B18B bottom end and I want to swap it out on my B16A2... my question is until I get my B16 built for boost would it be worth my money to buy the B18B from the junkyard and boost 9-10psi just to test out my IHI turbo?

I wanna build my high reving B16 for boost in the longrun, but would it be worth my money to buy the B18B bottom end and run that much boost since its more displacement?

Also I plan to do every bit of the work myself.

 

well, how big do you want to go? you can hit 400whp on a b16 at 1.6 L's of displacement.

Listen to your girls- size isn't everything

 

No I said for now I wanna use the B18... so is it worth my money to buy the bottom end B18 or just wait and build the B16 that I already have?

 

why?

use what you got.

 

lsvtec turbo

 

My concern is that I dont feel like driving around my B16 and ****** it up and since this is my drive every day car... what am I gonna do?

So really my question is whats the possibility of blowing a B16A2 at 7-8psi... I am also a good driver, all I ever do is listen to my motor.

I think I am just gonna buy the B18B and run 10psi for a testbed... thats what I wanna do just in case, cuz I can always go back to the B16 if the B18 blows.

EDIT: Its just the bottom end, and I can get it for cheap as hell too.

 

If you have the correct fuel managment you should not have a problem, but anything can happen. My buddy has a b18b turbo he blew at 8 psi tuned with the afc"hack". Just depends on the fuel managment. Why would you do all that extra work for no reason. Doing an lsvtec is more than just putting the head on. You have to combine a variety of items. My opinion it's to much to hassle with. Your B16 will be fine if it's tuned correctly. Don't fix things that are not broken.

If it was me I would buy the b18b block and prep it for turbo then you have a beast becuase you will have a "correctly built Ls-Vtec" Way stronger than b16a2.

don't go about your project bASSacwards.

Good Luck.

lol thanks, yeah I know what ur sayin... I dont plan to drive either hard until properly tuned... one thing I know for sure is that im not gonna take the B18B past 7500rpms boosted, but I think in the end I want a boosted B16 so im just gonna buy the B18 to have a backup... cuz god knows I can **** **** up whenever I get in the mood

 

B18b's are always a little more boost tolerate. If you want to take it past 7500. you need to prep the head, that's why i belive a good Lsvtec turbo set up would be great for you according to your plans. You will make a ton of power at 8000rpm's with fully built bottom end from a b18b.

If I had the money i would go the ls-vetec turbo route. I think if they are bulit right you have a wonderful set up and strong.

 

by preped head u mean PnP, w/stronger valves (high compression?) and say GSR cams since its gonna be boosted?

EDIT: add stronger springs w/the valves too

No i mean bottom end. The top end is for revving. your head will be fine. If you have the vtec head on. 8200rpm's is enough in my opinion.

 

yeah I was confused for a sec... im guessin that the pistons in the B18B are low enough compression for safe boost, so new rods and sleeving when I get the money ?

Booya! you got it. Sleeves, rods and piston will do the tirck also. I would do a little work on the crank as well new bearings, for those high revs. Then you will have a wise investment instead of swapping **** and waiting for somthing to break then swaping somthing else you will have better displacment and vtec as well.

 

thx for the help man, does ur name suggest what u are running?
