..don't mean to hijack the thread but quick Q about flashing your ECU do you have to do it after all ur mods or does it not matter?

 

does the spacer affect mpg at all? and do u need to do an ecu reset after installing just the spacer?

 

i got a blox spacer and an altered atmosphere throttle body spacer and got 13whp only mods,

 

show us the dyno sheet for that, if your not running an intake you actually make more on our car. Both together is too lean and you lose some power

 

Depends on your budget. If you want to gain 20+hp on NA motor, then I suggest getting a spacer, CAI, exhaust, and mabye HFC's. After doing all those bolt on mods, I strongly recommend you get your ECU flashed and tuned. Without tunning your car, your ecu thinks it is stock and you may end up losing hp! In my opinion, going FI saves money and the hassel doing bolt on mods. S/C is cheaper and more reliable then turbos, and unlike boltons, you can feel a big power increase. You can easily spend 4-5K+ on bolt on mods just to gain a few ponies. Going FI will cost 3-4k for the supercharger and 4-5k for the turbo. You can even DIY to install the s/c if you have a bit of auto mechanical knowledge.

 

i installed my stillen sc with my dad, and it was a great experience. great way to learn and save a a good amount of money. atleast if/when something goes wrong i can blame myself!

 

Popcharger, z tube, spacer or custom plenum, header, hiflow cats, exhaust, and new ECU w/tune may get you about that. Total cost would be about $3,000 after install and tune.

 

well the basic stuff is

exhaust
test pipes
intake
5/16 or 1/2 spacer

 

A set of Under Drive Pulleys from stillin.com is said to add 14-18HP for about 300bucks.

 

Hey guys i just wanted to ask a question real quick i have an 03 with all the stillen mods so far have upgraded the brembo brakes by adding brake lines and changing the rotots out stops very nice lol, i also have the stillen sways and damper anyway what would be a good clutch and flywheel setup, and spacer for me to go with i would like to keep the engine cover, only other plans are gonna be this summer which include cams and a good tune any help would be apreciated very much thanks ahead of time everyone.

 

"what it would take to squeeze an extra 20 hp"

About $2,000 since the going average NA rate is 1 HP cost $100 [+-].

 

Or you can buy a bunch of stickers and start putting them on your car. I hear with stickers you can add like 10-20 hp?

 

yep you get 280hp from the mt fuji logo and g35 logo, maybe i'll put a shelby sticker on there that'll be good for another 500hp or so rite?

 

the modified lower collector (MREV2) is not the best cost/benefit for the non-revup, however it does help incrementally... there are many things you should do first - most of which have been mentioned...

BTW, I have 1/2" spacer and a modified lower collector, a little more machining than then MREV2 version...

 

But isn't a TD exhaust alone adds about 10whp?
And with all the I/H/E, TP and a good tune would get to about 260~270ish whp?
