I have a non rev-up 04 G35 coupe 6MT and already osiris tuned with a popcharger, MD 1/2' spacer, MD ART test pipes, and Stillen catback...

After tune my car put down 233 wHP and 221 Ft/lbs TQ on a Mustang Dyno...

I am looking to get some more power but not planning on going FI for my own reasons... so I was wondering if anyone can give their input on what additional mods I can get to add some decent power....

I was thinking headers but is it really worth it? How much would I gain with headers and a tune?

What about pulleys?

Thanks in advance....

 

i think you pretty much got the bang-for-buck stuff covered. I think headers is your next potential gains, but install cost will eat into the $:HP ratio. I'd just enjoy the ride at this point if you don't plan to FI.

 

Yeah makes sense...

How about AMS pulleys?

 

I had my car up to 273 whp with a Utec, headers, test pipes, exhaust, plenum spacer and intake. I would not do it again. I would just save up and go FI. I know you said your not interested but just save your money then for something else.

 

FD gears.

 

^^ Yea FD gears would be your next mechanical mod. Doesnt add HP or TQ but it does put the power down better compared to the stock 3.3 or 3.59(i believe)
