Ive been reading up some on turbos etc especially for a b18. We are currently trying to prepare to build and turbo the integra. We have a b18a in the car now. Its an older motor, burning a little bit of oil, etc. We have got a spare b18b head. We planned on building that head up and putting in on our b18a block. would this be beneficial?
Now as far as putting a turbo on, what should we upgrade? the hp goal is 250-275 approx. we arent setting a psi goal b/c we all know how that will end up. so thats our hp goal and this car will be daily driven, maybe some track time but no major racing. what should we do to the head to prepare it? we were considering a nice port and polish but what other things should we swap out? valves? springs? retainers? we had thought about doing retainers and springs already. would it be beneficial? also cams. and if so, which ones perform best on a turbo motor? sorry for all the questions but ive tried learning some and im gettin there, wej ust need to start ordering parts and getting this project going!
As with most B series engines, the head is not as much of a concern compared to the block. If you are having oil burning problems, I would change the piston rings out first, and check the piston ring-lands, and cylinder walls.
If you’re burning oil due to bad valve seals only, then just replace the valve seals. But in terms of a good flow for the head, I would skip porting a B18a non-vtec head, and just buy a Vtec head. (An unported Vtec head often times has the same flow characteristics as a ported LS-head.)
If you’re boosting on an LS, it’s a better idea to strenthen the block, more-so, than the valvetrain. (Since you’ll be making power with boost and not high engine speed, thus not really venturing into the area of floating a valve.)
Although, at the least, have the valves re-seated, and the head resurfaced, and the block surface decked. Next, I would spend money of making the block stronger. (I.e., sleeves, pistons, and rods.) The problem is not making high HP numbers with good headflow, but rather making sure the block can handle the PSI.
Xenocron, here on G2ic made 300 whp by boosting a stock LS motor, but made sure he pointed out that 300+ flywheel HP, is more than enough to crack your sleeves.
Also, are you located in Lynchburg? I’m down in Roanoke as well as Staunton.
well we think its burning oil from valve seals but im not 100% sure. we have the spare head so we might as well get a block too 
we just want it to be reliable for daily driving, etc. It would be ideal to build a whole motor but doing that + turbo takes funds that we just dont have right now.
yes im in lynchburg. i go to roanoke on occasions. was just there friday night. stanton, i dont go up to much but i do have family in waynesboro so once in a while i may go up but it isnt often
