Sure you can, but you won't be able to run much boost on factory internals or a very high mileage engine.

If the engine is mechanically sound then I would think 10psi or less of intercooled boost would be no problem with a good tune.

i would go 6-11 psi spring on the waste gate and get the engine tuned to more than 400 to the wheels. you can go a little higher but, youre asking for trouble.

Agreed the 2v can handle 450 yes I agree but the conditions of that engine varies. That means how bad or good someone treated it. Adding a forced induction beats on a engine especially when it's not taken care of. Running 8lbs I have seen on a stock 2v and make 410ish depending on what u have... fuel injectors etc... I am running the on3 kit now and waiting for the tune shop to release it to me lol i spent 5 days 9 to 10 hours a day installing the kit. Converting it from a kennebell setup to now a turbo setup. Let me know of I can help in any way.

S0, I just ordered my On3 kit yesterday. I did 60# injectors, 90mm MAF, paid for the welding to go with it, turbo and down pipe blanket, a/f gauge, boost gauge, 8lb spring, 320lph fuel pump and I have my sniper tuner ready to go. I will let you know how everything goes. I dont want anything more than 8lbs for a stock 123,000 mile engine. I am going to slowly accumulate the parts to do a full engine build and upgrade the turbo later. At least thats my plan for now.

That is all nice let me know if you help with the install I literally did it all it took 5 days but I took my time and worked and kids etc. But once I cranked it no issues except tuning.

Currently using SCT but it's at the local tune shop. I asked them to go over everything and make sure I didn't miss anything. So far so good tuning starts today. I will post everything once they tell me it's time to spin the tires.
