I would assume if it's got a good tune on it then you could get some good numbers... what are you shootin for?

 

[Kazooie]

400-450hp

 

[7M-GTE]

400-450hp

you'd be getting close there I think... but someone on here might have done it... I'd recomend getting 550's if you can b\c I'm not so sure that the stockers can handle that hp...

 

[Jspec7m88]

If you are shooting for 400-450, you need to be going AT LEAST 550's. With over 400hp, running 440's would be pushing it on the edge, therefore losing performance. To answer your question, YES, you could do it, but its hard telling what kind of fuel problems you would begin to run in to. Just go with 550's and you'll be plenty happy with your fuel setup! It'll be worth it in the long run.

you can make good numbers with a good tune but dont expect them to last very long

Exactly what he said.

I didn't see a fuel management on the list, so 550 will not work. Tuned ecu, HKS turbo, and with 440's will be close to that #s. HKS cams will also be an idea.

just spend the money and get a maft setup with 550's... or even maft pro if you don't have a budget...

1J has a MAP sensor. putting a MAF or AFM back would be wack...

[Kazooie]

[OneJoeZee]
