First make sure your motor is in tip-top shape. If your dead set on forced induction I'd go supercharger. Summit Racing has Paxton kits for a few grand which includes fuel system upgrades that you will need and the fuel managment system included (although it's not listed, just read the details below).

I haven't read to much into this subject for these motors and what kinda pressure they can take on stock internals. I've owned a few turbo cars and instaled several kits on friends cars. There is a large learning curve if you have no experiance with forced induction. It will be benificial to leave the tuning up to a professional on a dyno. You will be upgrading your entire fuel system to support the additional air being compressed into the motor.

It would be wise to have another mode of transportation untill you get all the tweaks worked out. Also when you start boosting ANY type of vehical, things start to break.

EDIT: Hmm just serched around the net for some more info on this. Sounds like there is no type of knock sensor on these motors, this is not a good thing when boosting a motor.

 

I've got a 2001 VW 1.8t Jetta that's worked for a long time, but that's boosted from the factory (only upped it a little). Whenever people add boost to a motor it severely decreases the reliability, and longevity of the motor. Basically if you add boost expect a whole list of issues to crop up. Like Topkin said there is a HUGE learning curve with forced induction systems, and I don't even know if it's worth it on the 360. Anybody know what kind of power increase comes with the summit supercharger?

 

Hahns5.2 runs (or, at least, used to...) a remote turbo on his 5.2 Dakota, and doesn't have any unusual issues. If you don't go overboard on the boost, it can remain just as reliable as stock.

 

Well I can't imagine the power gains would be that great. At least not cost justifiable. You could get better performance without having to bolt on a turbo and run the bare minimum amount of boost. It would probably cost about the same too.
Well if one of the other members runs boost I'd be interested to see what kind of power they make.

 

Gotta agree with ya there. For the thousands you would invest, you would get maybe 100 extra horseys. Maybe. 408 build would probably end up cheaper, and put more power to the ground as well.

I think Hahns has some dyno charts posted in the General Discussion section.

 

Have a look see, some dyno sheets there as well. Not my thing thats for sure.

Yeah, some vehicles are better off without.

 

You can actually run a lot of boost through these motors with a minimum amount of work if you know how to tune and keep IATs in check. Stock headgaskets will let go around 10PSI. Fix that weak spot and they're known to take over 12PSI and up to 18.


I have 60k boosted miles on my motor from 7-10PSI
