cam and crank mods

[JLbeast]

im going to do a sc build on the 2.2l, and also did alot of reaserch on the sts rear mounted turbo and i dont see any prob with mounting that on with the sc, besides certain spacific charged mods such as the cam shaft. I was wondering if i should go as far as getting a new crank, boring the block out and all that, or just upgrading the pistons. Would the 2.2l crank and pistons hold up to all that or should i upgrade? and as well as the vavle springs and all that?

also what about rods and sleeves and all that stuff.

you will need to fully build the base model engine before twin charging

you dont have to chose the parts listed but a good bit of the engine build parts are there

2.2 Forged Turbo Info

looked at the list, makes sence. thanks, but nothing about the crank shaft, so im guessing that it should be fine then? cause if thats the case, then im done striping down the motor and i can now start getting parts and all that stuff.

you dont really need Cams for the power you get with a turbo, can get get a set of OEM cams and have them custom ground for turbo applications...more than likely you will have to find some turbo grind cams anyways. im not very familiar with cams tho

i have done some reaserch and there is different stages and milled cams for either sc or tc applications.

and i was probly going to go with the sc stage 2 for more being that most of my power will be coming from the sc. I will only be getting around 7 psi from the sts.

oh ok the block will hold if built right.

[JLbeast]

U think that I should upgrade the crank shaft, or leave it?

[cobalt123]

Well if your going to be sleeving and building the block your already going to be spending a good bit of money, you might as well upgrade it.

[JLbeast]

my crank is good up to 450whp. and if i want to upgrade past that, then ill be looking at dropping around a grand just for the crank. Im going to stick with the OEM crank.

whats the bore of the block 80mm?

[JLbeast]

should i go with the a-beam rods? whats the difference between the h-beam. besides being that they are much cheaper.
