if i were to go totaly nuts with performance mods and work with an engine.....which engine would you suggest? B21FT or B230FT? i have a B21FT in the car now but dono what kinda shape its in (jus bought this flathood thats been sittin around for 5yrs). i know it ran good b4 it sat. Turbobricks.com has a b21FT as being able to push 250ph and not much more and a B230FT all the way up to 400hp. Then i remember readin about this guy in Sweden (i think) with a 600hp 240 with a B21ET.
I have the B21 but i was hopin to be able to get more than 250hp by the time im done with it. What do you guys think i should do? do you agree with turbobircks or do you think i could safely get more hp out of the B21FT??

Thanks for all the help.

i agree with other thread/b-21 turbo intercooler,late model intake,cam etc. and megasquirt fuel system.it will suprise you!

Displacement = power. And the B230FT has the somewhat more responsive and adaptive LH fuel system, though I suspect fuel economy isn't going to be a concern the knock sensor with the LH fuel/EZ116K ignition may help keep detonation in check. However the B21FT is a more bombproof block/bottom end, and if you do try radical mods on a B230FT you'll want to start with 1990 or newer (if I recall correctly - the experts should set me straight if I'm wrong!)as it has the wider, stronger connecting rods & offset wrist pins to minimize piston slap. If money's no object you can build a 400+ HP B230 or B21. There's an article somewhere out there (TurboBricks, perhaps?) about the Homologated racing series 242s that Volvo produced, which exceeded 400HP from B21FTs using water injection among other things to minimize detonation & maximize oxygen content of the charge - water, subjected to the heat & pressure of combustion, reduces combustion temp through evaporation (instead of using fuel dumping), and then is broken down into its component elements, O2 & hydrogen, thus increasing combustion efficiency. Have fun!!
