out of that engine? its very very doable. not hard at all.
trick is to sign alot of checks with 3-4 digits to the left of the decimal point.
14:1 compression, 120 octane race fuel only, about $1000 in head work, custom ordered rods and pistons to handle the power, a balanced and forged crankshaft, might need to sleeve the block, custom manufactured axles to hold up to the torque, a reinforced manual transmission with a traction-lock differential, custom made intake manifold, a re-programmed ECM, about 32-42# injectors with a larger fuel rail and fuel pump...
need i go on? i know how to do it, can you fund it?
I bet it could be done with just the 14:1 pistons, custom intake manifold, huge throttle body, huge valves, cam, ported head, and header, custom chip, for lot's of timing, big injectors, and the use of high octane gas, and a strong clutch.
The stock rod's, tranny and axles should beable to take 200hp.
But that's a lot of machince time and custom parts, not cheap...thousands of dollars....or you could just slap on a $300 N20 system and hit 200hp by the end of tomarrow. (with supporting management)
I put a viper v10 engine, 32" rims, low profiles, eibach 21" drop springs, twin t66 ball bearing turbos, a 1200 shot nitrous system, 6 audiobahn subs, and a headrest dvd player on my push mower. Seems to work well.
(Don't believe anything I say, but that would be the shiznit, wouldn't it?)
