I have some extra cash around $100 whats the best performence mod(s) i could do for a 98 z28 auto ? right now i have a custom lid/intake with K&N filter, EGR Delete, Custom exhaust, gutted cat. any suggestions would be great

 

With only a 100 bucks you won't be able to do anything performance wise that you haven't already done. I say hang onto it and save it till you get a few 100 more.

 

I would get the Cold-Air Induction Package:

Better would be the FlowPac kit:

I don't like the K&N product too much...

When you did your EGR delete, how did you do it and stop the SES light from showing up? Can you detail the steps you took to delete it? Pictures would be great if you have them.

 

ive got that scoop, however i didnt use the little strip to block off the top of the lid, i figured the more ways in the better. ive always wondered if it works better using that little strip

 

If you have the SLP hood scoop and the SLP under air intake, then do leave off the block off strip -- the under air intake will do better at higher speeds and in general, but the hood scoop is ineffective at higher speeds since the air just sort-of bounces off due to it's location -- according to SLP. Call them if you want confirmation...

 

Thanks for the advice i would do the flowpac but i already modified my stock lid so its the same thing as a SLP lid. For the EGR delete its very simple all you do is unscreaw the one bolt thats holding it in. Pull out the EGR and use a grinder or cutting wheel and cut it right off its that easy all it dos is restrict airflow and by cutting it off it still works perfectly fine and wont set off your SES light. Heres the link to how to do it http://www.chevyhiperformance.com/te.../photo_07.htmltheres also a free CAI mod you can do i would have pictures up, but i cant find my camera [sm=headbang.gif]

 

agreed

there really isn't anything else except maybe a 180 degree thermostat.Or a manual fan switch to keep the car a bit cooler while standing still, which has the same effect kinda as the thermostat. A straight piece of tubing instead of the accordian stock one will squeeze a little bit more out. Other wise save till you have more enough for something that will make a bigger difference.

 

yea I'd save it till you get a couple hundred more

 

If it was me and you would like a neat mod I would go with a cut out, they are cheap and gain very minimal hp but it will really scare the neighbors and make your car sound like a promod

 

Do the cutouts negatively affect the exhaust flow when closed? I would assume they do on ones I've seen that are like a Y, since the exhaust would create turbulence going into that dead-end. Anyone seen any better designs w/out this problem?
