Header/Exhaust/Intake/Chip recommendations?

[NWPzr1]

I've got a customer interested in installing a full exhaust system w/headers on his 90'zr1. I'm also looking for a Cold Air Intake system and a performance ECU chip to compliment. The throwout bearing is making noise as well and I'll have the transmission out to install a new clutch/pilot/throwout, this should ease header removal/install I'd assume.


We're pretty much looking for a somewhat loud exhaust, and I've looked around but not sure what brand I'm looking for or where to find or even what they sound like so I figured I'd come here and ask. Customers exact words, "I want it an inch below obnoxious".....

I've looked around all night... but looking for personal recommendations/experience/info on an intake system, exhaust system w/headers, Chip, and a clutch kit setup while I'm at it.... As for the chip/tuning, any recommended tuners in the Chicago area?


Appreciate any input.... thanks:cheers:

http://www.zr1specialist.com/index.htm Marc is the man in your area for some suggestions as to what combos work.

Also, the guys from the FBI ( Fast Boys of IL ) that hang out here can give you a lot of insight on what combos work well.

NW,

There are quite a few of us here in the Chicagoland area. I'm in Bartlett,
Lgaff is located nearby you in Crystal Lake.
The FBI have a number of different LT-5 configurations as far as mods, tune(I do my own), displacement, exhaust. Marc Haibeck is the main guru here, but a number of us are DIY'rs. Welcome to the club.

I have a ported intake ready to go also if he wants another 25-30rwhp

$700+ his intake as a core

[NWPzr1]

Great, good to know.... thanks for all of the info tomtom72. Does Marc have a dyno?

Thanks XfireZ51, Crystal Lake is right down the street...

LGAFF, tempting.... so tempting in fact that I know he'd do it, we'll see as I just did the injectors a few days ago. I'll run it by him and let you know for sure.... 25-35whp? nice! That would compliment the other mods nicely.

[LGAFF]

Putting an alternator on my car this weekend....Borla with X pipe and Watson headers.....sounds pretty mean

Nice bark when you blip the throttle

391rwhp with no tune

Marc doesn't have a dyno, but rents time on one as needed to put the "shine" on his superb tuning. Marc has developed various base "tunes" for different sets of mod combos that you can buy. But, as always, if you want the most out of it, then dyno tuning is a convenient way to address a wide range of stuff.

Marc specializes is the ZR-1 and your client is lucky to live in the Chicago area as Marc is one of the best of the best ZR-1 mechanics you'll find. When you get to that point, you could just give the car to him to install the chip and tune it. He'll go all through the thing to make sure nothing is out of whack before wasting time on the dyno. From personal experience on several occasions, including tuning, you won't be disappointed!:cheers:

Thanks for the vids, so much better than staring at a pic of the exhaust. Are you going to be running cats?

If you don't mind me asking, where did you get your exhaust? Recommend anyone decent, or even websites for ZR1 exhausts/parts I could take gander at?

Also, I'll take that ported intake off your hands in the next week or two when I've got time to rip that plenum off and drive out to you(I'm just east of McHenry). I'll let you know asap...

Do you by chance have any pics of finished product? I'd really like to see it if possible before I go removing his plenum again.

[LGAFF]

I have pics of the porting, IHs need to be refinished....I would run them over some time for a look, easy to paint or powder coat. I have done 9 intakes......send me your # and I will give you a call.

Excellent, great to hear. Sounds like him and I will get along fine...

I'm considering getting a couple baseline dyno runs in soon(stock).... so I'll be giving him a call this week. I'll let him know how highly he's been recommended as well. =D>

These are the IHs I media blasted them with crushed walnut

[NWPzr1]

So, I just noticed the carbon fiber hood Marc has for sale for $5k..... 15lbs/$5000? Is that a typo?ha That's a big hood!

Looks good... They claim 25-30whp with just the ported upper plenum and the stock I/H's?

Or is it all a package deal for $700?

[LGAFF]

The $700 is ported plenum and IHs....I also get your unported pieces as a core

Still have the ported items available? I'll be ready to disassemble when the rest of my parts get here, I'd assume in a week or so.


Also, wanted to thank all who recommend Marc Heiback... Met up with him today to baseline the Z(320whp stock), very nice and knowledgeable guy. Looking forward to working with him when the car is done and ready for a tune.

Also, made up the parts list today... still need to verify/authorize everything, but here's the plan so far.....

Then of course the ported plenum, IH's and at last send the car to Marc for a couple days for a full dyno tune.


What do you guys think? Any opinions?


Thanks

[LGAFF]

Still available...pm sent

Paul.
