What MODS Have You Done To Your ZR-1??

[Blue Flame Restorations]

Interested in what fellow ZR-1 Brothers have done to their beloved Z's and WHY? Benefits???? Pics are a plus!!!

ALSO:
* When you were looking for a ZR-1, did you want a bone stock Z or one that was already modded?
* If you bought a bone stock Z, did you end up modding it?

bought the 90 stk . then did jeal headers and exhaust . but wanted more so had corey port inj housing and plenum and 410 gears . that lasted til i popped a head gasket 2 190 k miles . now putting in new short block. the 92 callaway car bought in 08 and put coreys headers and my own design exhaust.put in 410s from 392s went to coreys and did the secondary delete and had him tune she is at 410 rwhp now . the secondary delete was a awesome mod along with corey tune .car got 23.8 on the 1600 mile trip to coreys and 27.1 on the way back . thought i might have made an error . but she consistently has been getting 3 mile per gallon better on my weekly shopping trips than before . plus she seems to have better bottom end and mid range . will find out this weekend if she can run better than her 11.94@ 118.72 best before the last corey trip

We all have to understand that once modified to our liking, these ZR1's are worthless :handshak:


Sometime's I crack myself up :mrgreen::mrgreen::mrgreen:

[Fully Vetted]

I bought mine already modded. I knew I would end up wanting to do the port work, exhaust, secondary elimination, etc, etc. and since you never get your money back out of it I found one already done. FBI did all the work and the previous owner paid for it. Win, win.

All I've done in the 6 months I've had it is Series Ones, braided oil cooler lines, some Carter bling and a bunch of other little mods. My next big mod will be 4.10's.

Besides that.............they are skeered to drive a modified ZR1 :p

I went through a phase in my life when I modified (mod) as many aspects of my cars that I thought would be "cool". The point back then was to personalize more than optimize or improve reliability or or or....
I made changes that I later regretted (for various reasons).
Since that time I've changed a bit. Rather than put the latest "cool" looking stuff on the car like pin stripes or dice hanging from the mirror or the now popular lights under the car, I focus on enhancing existing systems. To that end I've modified:
1. exhaust
2. secondary actuator system
3. underhood engine lamps
4. shifter
5. suspension bushings
6. radiator stack
7. AC system
8. ZF6
9. fuel pump assembly
10. LTPWS sensors
11. ECM chip
12. battery access fender
13. Bose system mod
14. Wheel polishing
15. injectors
16. thermostat
17. air intake filter housing
18. Fog lamps

Here is what I refuse to do, it's too scary for me but I'm ok that others do it because of snow or other geographic and/or terrain issue. I just hope the disease does not trash too many of our cars [-X

Excellent post Scott. :handshak: I actually started this Thread due to our recent conversation on the CF where you stated the following about modding our cars.

Please don't see this post as a personal attack. It's not. :handshak:

I was so shocked at your response that it got my curiosity going and I wondered just how many folks here modded their Z's and what they had done. Just wondered if I was in the minority about modding cars or removing secondaries.

Defintion of Kludge
http://www.thefreedictionary.com/kludge

Scottfab CF Post
I leave most systems alone for resale and for documentation reasons. Who want to buy an undocumented mess. See definition of "kludge"

I've fixed my secondary system twice in 15yrs. Easy as cake.

ALSO to be considered is the ability to remove the key if someone else drives it. This was the primary reason for GM to put it in and it is a good one.

Keep your LT5 and LT5. Don't make it into an LS5 or LT4.9 or whatever it becomes when you rip stuff off it.

Still to each their own. Hang fuzzy dice on your mirrior after you rip out your secondaries.

As long as it's high performance air that improves reliability it should be ok with them. It's when all the air is ripped out and nothing in it's place that they'd draw the line. Still there are improvements with ripped out air that would work:

I try to be careful with my choice of words. If something IMHO is removed then it's "ripped". If it's altered and replaced then it's "modified". If it's later put back for whatever reason (like discovering it was useful after all) then it's "restored". If it's "jerry rigged" then it's a "kludge". If it's held together with bailing wire then it's "fixed" :-D

I am not sure anything on your list is a modication...looks like an excellent list of maintenance items to me ......just saying :handshak:
ah but you'd be wrong. Everything on the list was modified not just fixed. In some cases the redesign was extensive, in others minor.
The list of simple "maintenance" is much much longer. For instance on the door chime I simply soldered a few cold solder joints. On the CD player I fixed the ribbon wire to the head. On the seat belt I re-tensioned the spring. On the brakes I used ceramic pads, on and on and on......a complete list resides only in my repair log which dates back to 1997. Most if not all of my mods were documented on the zr1netregistry.com page. Some weren't because I was not sure they'd be reliable. Since then they've proved to be by not having to revisit them for the same issue.

I was reading thru the posts and was LMAO too funny,good stuff.

You can make the power key work even with the secondaries removed it will work like a rev limiter i.e.you can set low power not to go past choose any rpm 2500-5000rpm.

Good thread!

Mods... It's like a desease!

Beautiful as she was, I wanted a Z since 1990. And fortunately, someone(s) took good car of mine untill I could afford her! ;)

In the interim, I bought this beautiful 95/ZF Vette...

http://i185.photobucket.com/albums/x220/6PPC_bucket/Vettes/Zaino-vette-smaller.jpg

...but kept looking for a nice Z. One day it happened; got a phone call from a dealer friend of mine, climbed into this fabulous red 90 and went for one test ride. Whata rush! I tossed him the keys to my 95, and never looked back!

http://i185.photobucket.com/albums/x220/6PPC_bucket/desktop9-4-11Large.jpg

It was at the Crown Point Corvette Club's shootout where I first saw the potential of "The Beast". Pete, followed by Dominic, ended the scoffing and smirks by many sitting in the bleachers when these "C4s" came up against their club's mighty C5/6s. But when Pete and Dom lined up for their second passes, the bleacher sitters went silent...except for one voice that said, "What's a ZR-1?" The dye was cast: I was going to do "some" performance mods!

I come from a long history of modified hot rods; beginning with alcohol fueled dirt track racing and the usual gear-head series of noisy, nasty, street rides. But, the ones I always got the most pleasure from were the "sleepers" - a V8 Vega and an L79(427) BBC El Camino...were a couple of my favorites!:p

Coming to the line with a "RACHETAH-RACHETAH" BBC with huge cam overlap sounds nice (menacing!). But, being fast is expected and comes as no surprize. BUT! Coming to the line without outward signs of being nasty...and blowing away a RACHETAH ride...is ever SO sweet! So, after seeing just that happen on Pete's first pass - cutting an 11.4x @ 129.x and chewing up a couple C6 Z06s with his "stock" 5.7L LT5...I just HAD to do some MODS!

And, it is my great fortune that I live in FBI country where performance and racing flows in the veins here! And, it was with the collective guidance of Marc, Pete, Al, Bob G, Kevin C, et al, that allowed me to make mods (see my signature below - except for "just a few" FBI secrets, not listed - on pain of death[-X) that significantly increased performance without jepadizing the reliability.

I did my porting in stages; top end and headers first - starting out by uniforming the runner sizes to approx 36mm on the plenum and the IH's, and tapering the runners in the heads down to the valve guides. I never had issues with my secondaries, per se', but after the porting, the butterfly plates no longer fit the space they now occupied; NOT to mention they're technically in the worst location, far as laminar flow in the runners goes. (I also sleeved the inside of my air duct between the K&N filter housing and the air horn - mostly to keep the duct from collapsing, but also to smooth the air flow somewhat.)

With SW headers and X pipe, and 3" pipes to the muffs, I was near 400 rwhp...Not a bad boost for a "bolt-on" mod (OH! And one of Marc's chips). But, good as the increase was, it only whetted that "WANT MORE" monster within us! So, when I discovered a leaking exhaust valve (likely the result of a bad OEM injector), I took the opportunity to complete the porting of the heads, according to the "FBI" patterns.

(Head porting of the LT5 is NOT for the faint of heart, BTW. There is "quicksand" one can step in if one isn't kerful! I did mine for my own to learn first hand about these LT5 heads. But, I'm not in the bitness. So, unless you are a welder, or have a welder friend experienced with aluminum heads, I say it's prolly best to let Marc or Cory et al do the porting, or have Pete CNC them for ya...just sayin!;)

Add a nice mult-angle valve job and a "few" tricks from Pete and Marc, and I installed a Fidanza FW (amounts to approx 15 hp on the dyanamic dyno) and I'm at 432hp at the wheels. Voila!!

A stock bottom, stock cammed 5.7L motor that gets 26+ mpg hwy, crisp throttle response, and nobody would know from looking at the motor or listening to it idle that it was modified...UNTIL you whack it. Then it screams like only the LT5 can do!

Is there more to be had? I think so.


The TB is stock, except for coolant bypass.** Money is tight (again), but I intend to bump it to 63mm soon as I can.

**Reduces intake temps, especially when staging at the track where every degree of heat is working against ya!!

The Magnaflow muffs neck down internally from 3" inlet to approx 2.5" abruptly! Those are going to be replaced with the Dyanmax 17228s and fixed with the Z06 type vacuum actuated gates that seem to work so very well 'round here!

And one other item to be tested that Marc and I are fooling with - might be worth a pony "or so" at the wheels.

Considering an electric water pump - good for maybe 8-12 horse, but recent failures of same in Pete's car resulted in having to replace the motor. So...That gets back to that "reliability thing". An additional sensor/warning light for current draw on the pump motor might be the ticket, methinks.

"Ripping" the AC compressor might save some weight!

Moving the battery to behind the passenger seat makes some sense, from a weight distribution standpoint.


Something else to ponder... E85 and FI in combination is "interesting", tho there's that reliability thing again.

And, then maybe someday there's stroking and sleeving...OMG...Nuff said!

Well, in the end I gotta say, I LOVE the way she drives now. It is perfectly happy to cruise anywhere in town, in traffic. And, as Pete says, when you "whack it", all hell breaks loose! This is the way they should have come from the factory, IMO. And, if anyone else was contemplating modding the LT5, just ask anyone from FBI land what they think of their car's performance NOW!

P.

As I'm waiting on parts and such on other projects, I'm going to "rip" the roof off of #444 and fit the conv bodywork to it.

The plan is for the motor in the Turq Monster to go into #444 when we build the stroker for the Turq car. I'm buying a donor car for #444. Hopefully, a 94-96, 6 spd car for everything needed. I like the newer dash and sport seats. The makings of a Shinoda Convertible.

Tony, so that's what my car looked like before I did a few mods?

Yes sir indeed. Don't you just love sarcasm?
The easier question is to ask what have you not done yet to your car. I have owned it since 1998.

Need: stroker, rollbar, maybe Nitrous.......then I think I'm done. Maybe

[LantanaTX]

I bought my car a couple of weeks ago and still trying to figure out what mods it has. Carfax says it was two owner car. first owner traded it to a dealer and second owner bought from dealer so history is lost. The obvious mods are the gray paint, color keyed door handles and wheels.

I did find something interesting folded up in the FSM that came with the car. It was a printout of an email from Doug Rippie Motorsports in 2004 to a Jan Timmerman that referenced a huge list of engine parts including pistons etc. I sent an email to Jan Timmerman to see if this was the original owner and what was done to the engine. If buying a ton of parts from Rippie, maybe my engine is not stock?

Lets hope Rippie blessed your engine.

Tony-..I know that hood scoop is an overlay on the stock hood..Who makes it?Greenwood?

[Schrade]

Mine was 'bone stock', except for the 91 - 95 body conversion (think it was done since the car had taken a hit in back, although I just found a piece of glass inside the hood mount, IN THE FRONT!

The ZF was first to go, now the 2' port hardware, now it looks like the AIR plumbing will be removed, traded the Aluminum pinwheels for Black A-Mold [repro's] on the corners, now the exhaust is migrating from the sigline to actually ON the car. And the painted top end, the GS stripe to take the edge off the Red - DON'T like Red...

Nice mod list,Hib. Tell me more about your headlight upgrade.

Couple of things I would be interested in further.

Fluidyne Radiator - What affect or benefit was observed?

What year CTS-V lug nut covers? I have the plastic ones and the paint just flakes off after a bit.

Fluidyne Radiator - What affect or benefit was observed?

The Fluidyne Radiator in conjunction with a 170° thermostat, coolant mix of straight water and Red Line Water Wetter and revised fan-on strategy provided a significant decrease in peak ECT in hot weather, high load situations. Unfortunately, Fluidyne discontinued their 2G ZR-1 radiator a number of years ago.

What year CTS-V lug nut covers? I have the plastic ones and the paint just flakes off after a bit.

I got rid of the plastic covers for just the reasons you cite. The CTS-V covers are stainless steel and look really good, but I don't know what year. Someone else told me about them a long time ago and I do not remember the specifics. Sorry.

Headers shouldn't de-value a 1990 ZR1, right?

Headers shouldn't de-value a 1990 ZR1, right?

It depends on the owner/seller/buyer and what motivates them and what they want to do to with their car. If you want a NCRS Trailor queen the answer is yes. If you want to drive your car and enjoy it No. I am not knocking the NCRS program however if you have a sub 1000 mile car and you plan is to show it then I think it would be almost a crime to mod it as it’s a rare opportunity to show the car to others as it was released by GM. However, once again your car... do as you wish. You can also keep all the original parts if you want to return it back to original. Enjoy your car no matter what you want to do. When I bought my first car I bought it with about 49k miles with full intention of modding it to my needs.
