Default Tune ups/future plans.

Hey guys, looking for a little direction here.

Newly bought 95 Z28, its got about 56k miles and it seems to run great.

However, before I start modding I want to make sure it still has all, if not most, of its original power so I was looking into getting a shop to get it tuned up while I was spending time with my dad this week.

Shop said a tune up was plugs/wires and checking for timing and knocks?
Is that really all I need, cause I could just do that myself and save the cash.

Once I'm satisfied with the stock set up I was going to look into an LS1 conversion intake, LT's (no clue on who's) with just a Y-pipe set up to a TSP Rumbler catback, I liked the sound from what I've heard and its relatively cheap, but I'm still open to suggestions.

I LOVE GMMG's catback, do they offer just the chambered muffler?

It's an M6, I'm good on tires/rims and from the other thread we thought it might already have 3.73's...oh and it definitely has posi

Just looking for a nice DD with some bolt on powuh.

cold air intake, headers (longtubes), catback exhaust, electric water pump, under-drive pullies, dyno tune. Just a few things that'll wake her up without getting too involved.

Has coolant ever been changed? Fuel filter? If it is running decent I don't think I would let some shop change plug wires! Hold off on that until you do your LT. Have fun!

Apparently no one has seen my introduction post lol.



here's the link;

Its got a K&N CAI on it already, but I like the lid more.

Are Pacesetter's LTs a good product?
Anyone have any info on that TSP Rumbler?

I was also thinking about doing TD's with an x-pipe, catted, to Dynomax's Bullet Mufflers, but my exhaust shop didn't like that.

gmmg doesn't sell mufflers but stainless works make a chambered muffler and theres powersticks too. but if TD's is what you want then find a different shop. get an OTVC(over the valve cover) kit for the wires and don't forget about a PCV valve on the tune up. I wouldn't bother with a dyno tune yet, mail order should be more than sufficient.

Thanks for that awesome link!

I was just about to ask for pictures to show, but this is much better!

I will be running cats since this is a DD car and I don't want to have any problems with emissions, where would you put the cats in a set up like that?

One on each pipe after or before the crossover?
