Hey guys I was looking into boosting my b18b i have in my garage I had a b18c on boost 283whp/214trq on a jdm itr 2.5" exhaust and muffler,(pretty impressed especially with it making that power on that restrictive exhaust and muffler) the motor was 100% stock and is now starting too burn thinking of doing:

b18b - with a piston/rod not sure what piston but eagle rod. trying too make 320-330whp... may do a intake mani and throttle body aswell as valve springs and retainers, was wondering how attainable this is with the b18b.

and also whats a good size turbo for the b18b so my powerband dosnt have a huge peak ! lol

thanks

 

50 trim

 

also i heard ls rods and pistons in a gsr bottom end is good for boost aswell as a cheap oem build

 

Those power levels could be reached on the stock rods and pistons with a good tune and supporting fuel system.

 

why'd you stop using the b18c?

 

get a 50 or 57 trim, like stated you can do that on stock internals 300, it will do 350 but the ringlands are weak and they dont like much more than 300 unless its a spot on tune.

stock intake manifold will be fine, if your going to upgrade the valve train think about cams for more powerband. Im selling cams cheap for the b18a/b engines. PM to find out more
