I'm getting ready to start a complete build on a B18B. Buy a junkyard block, tear it down, clean it, and put in forged pistons and rods, port the head, new valve train (stainless steel valves, dual valve springs, titanium retainers), port the intake manifold, all AEM fuel components except for the Walbro 255lph fuel pump and 550cc injectors. Bolt on a maxrev turbo kit and gsr tranny with LSD. I'm not too worried about what specific turbo I'll be using. Or if I'll even go with a kit. Getting the engine running non-turbo is more of a priority than boosting. And I will fire it up without the turbo just to tune it and make sure it has no problems. After it runs I'll start worrying about the turbo setup. Just figure that I want this for a drag car and daily driver (I'll run it on low boost so I can run pump gas for dding)

First off, about how much boost would be safe? (I know thats a little hard, but I'm hoping for just an estimate). About how much WHP should I expect? I've been told everything from 350 to 500. Last, how much do you think this will cost in the end taking into consideration that the whole block can be had for $900 and the P&P head with the new valvetrain for $1000. Take into consideration blueprinting and balancing.

stock sleeves id say 300hp max, sleeved block and the sky is the limit, actually fuel grade and internals are but u get the point. tunning is what will make your block live through boost.

 

maxrev turbo kit


full-race

 

.55 bar on stock block with 126k miles. no problems with boost yet. going to be doing complete rebuild soon, though.

 

do you mind me asking why you only boost .55 bar? i have a b18b...and im going w/ .7bar

 

500 whp just might tske some sleeves and a big *** turbo @22-25 psi with a ls with rods and pistons you can boost safely up to 15-18 psi and make aroun 350-390 whp but this will take a good standalone system and a good tuning session
