6th Gen mods

[dallasmax]

I am thinking of doing alot of upgrades but, I am curious of what performance gains I will get. I am looking for both H.P gains as well as increased Gas milage. I drive about 600 miles a week so I need the extra efficientcy but, want it to haul A** when I step on it. Has anyone had there car on a dyno to measure H.P. gains after upgrading the filter to a cone, y ppipe, and cat back?

Well here's the dyno chart from Fujita:

And a dyno with Fujita, NWP IM Spacers, Light weight pulley and SAFCII, Cattman Y-pipe and the Nismo Exhaust courtesy of Apollos2



You can also get the ECU reflashed...

I have a lot of mods and I travel a lot and have had no major problems. This is my last dyno. From what I was told and you should check it out is that a ECU flash on a automatic is no good since the ECU will reset it self.

With HotShot headers and other mods.



With a 50 shot of juice.

not bad with a shot but you're short 25hp as they came with 265 stock...where'd those go???

[johnnyd6404]

265 is the power the engine makes the wheel horsepower is allways lower... lost in the transmision.

[allensteiner]

i thought the 265hp was dyno stock, more from the engine.

[johnnyd6404]

They just dyno the engine so they can advertise higher horsepower when the transmission goes on the engine cant transfer all the potential power thats why you hear people talk about whp (wheel horsepower). I did hear that the GTR is advertising 480 whp which propbably translates to close to 600 ponies the engine is putting out.

Johnny, What mods fo you have?

[johnnyd6404]

I've just got an injen intake and megan racing catback for performance. Exterior I've got chrome pillar posts, clear corners with oznium leds same leds in the parking lights, luminics pure blue h3 fogs and 50% tint all around. I'll get a pic soon. The exhaust is the best performance mod my car hauls now the intake only gave me minimal if any gains but it sounds awsome, it did increase my mpg by about 20% tho.
