good avice on engine mods *not doing a top swap*

lookin to get som extra HP and in a week or two im lookin to get the TDC intake (so TDC u dont have to pop in lol but ur advice is greatly appreciated) and im not really sure what else to do or if the TDC intake will do much b/c i dont have any mods at all yet

If you don't want to get any sort of forced induction, this would be my preferred list.

2.5" DP (no need for 3")
Plog
some sort of intake
ER rockers
HV3
ported throttle body

It'd be quick for N/A.

nows all i need is a trandlator for those abbreviations lol

i had all those mods when i was N/A....it was ok...the M90 was the greatest mod i ever did

Well basicly the only thing you can do is exhaust and intake. That is what's going to make the biggest difference anyway.

Whether your s/c'd or N/A'd the cooler the air the better. You will notice a difference in performance with our Intake.


The above rockers that were mentioned is basicly giving you the best performance you can get without buying a cam and tearing into the motor.

2.5" DP (no need for 3") DP=Downpipe to replace stock exhaust downpipe and U-bend delete
Plog Plog= Powerlog which replaces front exhaust manifold
some sort of intake
ER rockers
HV3 Insert for upper intake manifold
ported throttle body

It'd be quick for N/A.

Hope this helps..............

yeah that setup wont be too bad for n/a... but no matter what every time you hop into a gtp youll want that top swap... id say bite the bullet and swap or sell and get a gtp... it was well worth it for me

its a pretty big waste of money to try and get any power out of the n/a motor.

Sabrewings summed it up pretty well, you'd prolly have a high/mid 14 sec car.

When I was N/A my best was a 15.3 with a 2.2 60ft and traped 88, that was on a cool night. My mods were removed headlight, stock air box, plog, zzp dp, intense s/k, overkill pcm, solid motor mounts, slp catback (not that that matters), and 4* of knock.

I ran a 14.8 at 91 mph with a 2.09 60' with a 3" downpipe, Wizaired Intake, koni adjustables, S1 throttle body, Corsa catback, and a powerlog. I was running a ZZP pcm with some adjustments to the MAF table when I made that run. I'd say there was definitely room for improvement.


I wanted to stay NA, but I got a good deal on some top swap parts and decided to take the leap. I'm still gathering parts for the build so I can't say how much faster it is.
