article states they replaced everything at 275, but stock cranks can handle about 600* not 800.

 

the 2.4 block is a poor block for boost, for it's cylender walls are tiny.

the 2.0 is the ***** block without using boost.

 

a olt on 2.4 > stage 3 2.0. but 2.0 is capable of much more due to the thick cylender walls.

but ideally, the 2.2 is the best block... they just decided to give the 2.2s the gimp computers.

but GM races the 2.2s

yenko only the 2.2 is really built for boost and none of them are built for spray. sure there are guys running it and gettin away with it but thats on a damn good tune. you run a 25 shot through one of those untuned and its gonna run lean and melt everything in sight.

 

news flash nic.. the 2.2 is UNTUNABLE. unless you do a standalone tune. and people are running 150 shots without a standalone.

 

thats why 2.2 guys are running huge shots of nitrous instead of doing a turbo build.

 

You will not melt your engine at 25 on any car.

 

I dont know about the 150 shot. If they are runing it its not near stock and must have some type of supporting mods. In fact there was a guy runing 75 wet on a 2.2 he was runing mid 14s with a few other mods. He had a back fire in the plastic intake manifold and well you know what happend. [>:]

 

yes. i will agree there. they are running ZZP/LSJ header and downpipes, Catback, Cold Air intake, throttle body, and the main mod, is a ALLUMINUM intake manifold off of a saab. they bolt right up. that right there will let you run a 125-150shot. 150 is pushing the clutch.. but only the clutch. that would also give you a high 13 - low 14. also, obviously you'd want colder plugs too. a 150 is also prolly the limit for the pistons and rods. but the crank will handle it. easily. the next step after the 150 shot would be a performance head.
