Ok so basically this is my question....What mod can I add that will give you a noticeable gain in power for the g35? I have my 2007 g35 and my bro has a 2007 350z and when I drove his car I can feel how much faster his stock car is compared to mine....aside from turbo and supercharger what can make the response feel better?

 

Plenum spacer, exhaust, test pipes
SEARCH

 

Nitrous

 

^^^His grounding kit if your an AT looking for better response

 

well like how much of a difference would you have with high flow pipes? i mean car will sound louder but would it be all bark and no bite?

 

What are your goals bro. This has been discussed in numerous threads if you search

 

tune & gears

 

Problem with most aftermarket things are its a test to see what will work well when used together. That being said. Are you looking for more hp or tq. I will swear i lost some bottom end with my hfc's but picked some hp up on the highend. I have a true duel exhaust though so its hard to tell the difference.

 

well maybe more torque is what im looking for, thats felt more than hp gain I would assume unless im wrong bout that

 

and goes is basically to one day go crazy and bore out cylinders and make my g into like a 4.2L and have vortec supercharger but thats like way later, for now I wanna do gains that will complement that for future

 

You should try a simple ECU reset. It made a HUGE difference in response. It was such an improvement I posted a thread on how to do it with just a timed series of gas pedal pumps. Just try it.

 

^^You should listen to Mark's advice. The gear swap will bring the power you already have to your wheels quicker making your car "feel" faster. Here's what I would do if I was bone stock and wanted more power.

5/16" spacer
HFC's
Exhaust
Gears
Osiris tune.

The first 3 mods will add power on your coupe, the gears will redistribute that power, and the tune will tie everything together and tweak as much power as possible very efficiently. Not only will you feel these changes, your car will be significantly quicker. Those 5 changes from stock will result in surprisingly good gains, just don't expect to make massive gains w/o going FI or nitrous.

 

You won't find better advice than this....^.... I'd go with the Motordyne spacer along with the HFCs and a true-dual cat-back exhaust like HKS not the y-back POS systems some members buy expecting gains or a good sound. After gears and a tune you'll leave your buddy with the Z in the dust. Just don't let your bud know what your doing until you've done a side by side....on the track of course!

How much does the Osiris tune cost, now a days?

 

osiris is for rev ups only? like that 2" timing adv bs? rev up only?

i have no idea what tuning is availble for my nonrevup.

and there is one nice "non true dual" exhaust system out there... exoticspeed r1t.
most exotic sounding exhaust ive heard on our cars...
