4g63 

A powerful but horrible engine "built" by Mitsubishi. To end the fued between the 3sgte and the 4g63, The 3sgte did come before the 4g63, which mitsubishi replicated in power but not reliability. 3rd gen 3sgte created 255hp on 7psi and the 4g63 creates 300hp on 18psi. A very unreliable motor that will probably blow before you pay that EVO off.

For your own safety, please do not mod the 4g63 or you can kiss it goodbye. Your best bet is to leave it stock and enjoy.

4g63T 

an engine built by mitsubishi during the DSM partnership between mitsu and chrysler. the 4g63 came in 2 variations, a turbocharged 195hp 1g or 215 2g engine for the upper DSM models, and a n/a 135hp engine for the 1g DSM's.

it had 3 major designs:

89-92 had the strongest bottom end with the big rods capable of handling 400hp stock, even with high mileage.

92.5-94 had a 1g 7 bolt engine. not as strong as the 6 bolt, but still a stout engine.

95+ (2g) this engine is garbage IMO. 35% of these have been reported to crankwalk. they have thinner rods than the 1g 6 bolts, and the head and turbo are designed for mid range power, sacrificing top end power. it may put out 20 more horses stock over the 1g engine, but the 1g 14b can hold 300hp without running out of breath, unlike the measly 2g T25 that cant hold anything over 250hp.

many people swap their 2g's for 1g 6 bolt engines to eliminate the worry of crankwalk.

honda guy: yo man i got a ex with vtec.
DSMer: i just got a shitty 4g63T.
honda guy: ill smoke you.
DSMer: i hope my tranny holds up.
