These cars should remain stock and not mutilated.

 

LMAO. . . .that is what I said about my 1969 Firebird I bought in 1982 for 500 bucks (blown tranny). It is still primer gray and people are offering me up to 35k for it. Based upon my experience, I have no doubt that the c4 will rise in value over the years.

 

In answer to your original question ... moding it the way you describe will not add any value to the car when you go to sell it. If you have room to keep all of the stock parts you are replacing, then keep them. When you go to sell the car, return it to stock. If and when you sell the car, then resell the speed parts here in the parts for sale section.

I added long tube headers & the LT4 hot cam kit to my LT1 auto and picked up 40rwhp

Best of luck with your mods and be sure to let us know what you end up doing.

 

I just re-read my post and it does look like I was attacking you. Sorry about that. I didn't mean to imply that you had no single mass experience.

My dual mass set-up was quiet at cruise but would clank quite a bit in neutral at idle. It would be quiet for a second, then clank, quiet, then clank, clank, etc... My aluminum single does none of that. It's quieter at idle because it doesn't clank like it did with the dual mass. During normal cruise there is no discernible difference, but there is a pretty loud noise at low RPM under a heavy load. Like I said though, the noise happened so infrequently and at such a predictable RPM/load that I was able to learn it out of my driving style in just a few hours. The end result now is a car that is quieter with a single mass than it was with the dual mass.

 

Are you sure your dual mass wasn't worn out and hitting the stops? You don't want to get caught up giving out bogus info about the dual mass, like someone did for the single mass.

 

I don't know why yours makes noise. I'm not there to look at or diagnose the noise. It could very well be the bearings falling out of your transmission for all I know. It could also be the single mass. It could be an exhaust leak, or a header touching the body, a rear end gear, a worn U-joint, or any other of a thousand different things. I realize that your not an idiot, and it most likely is the single mass, but not all single mass flywheel ZF6's are noisy. I don't think representing all of them that way is right.

I'll agree that based on what's read here that my experience with the single does seem to be the exception. However, in real life I've driven 2 C4's with the single mass, and ridden in another for a total of 3. None of them were appreciably louder than a dual mass car. However, all of these cars were using the McLeod twin disk clutch, perhaps there is something within the McLeod flywheel/clutch combo that helps with the noise.

I'm sure there are single mass cars out there that are louder than stock, if there weren't we wouldn't hear about it all the time, and yours probably wouldn't be making noise. But to explain the single mass flywheel in such a way that it comes across like there will be some deafening cacophony of noise coming from the transmission because of it is incorrect. I would just like the OP to consider the possibility that a single mass might not create the kind of noise that is typically represented here on the forum. Then again, it might. I don't really have a way of knowing how his car will react to the single mass, but neither do you.

 

I wouldn't worry about resale value, if you are worried sell it as having headers and exhaust only. Most guys won't pick up on it having 4:10 rears or many other mods.

 

Opions are like a**holes, everyone has one....

 

Thanks for the input everyone.

I'm going to mod away and hopefully I'll see some of you guys at the tracks.

 

No, I'm not sure. My clutch was in great shape when I pulled it out though. The car/clutch had about 61,000 miles on it and drove great, then I missed a shift at the track and the clutch disk came apart.

My car sounded pretty similar to other dual mass cars I've driven. My ZR1 makes the same clanking at idle with the dual mass.

 

i asked the same question a while back and it wasnt pretty.some members gave really good feedback and helped me make a decision,while others launched assaults and and are clearly too intelligent for this forum.
i asked this question at a club meeting,and they agreed i answered my own question.when youre around chevy or corvette guys and they ask you what you drive,do you say corvette or lt4,zr1,z06,L88.ect...
those who say the lt4 is or will not be collectible,are wrong.is the lt4 different,is there an rpo code,why does it have lt4 insignia,does anyone question an lt4 automatic,does anybody say lt1 istead of corvette?ect..
here is my advice;
if you mod it,keep youre oe parts for return to original if you need to sell it.even the oe wires are sought after.
i didnt buy my car as an investment,but a monetary problem could force a sale-im not rich.
soup that son of a !@#$$ and drive it.junior

 

that's right, externally -- no kiddie visual ground effects/mods.

tasteful wheels and/or paint can be great. modding for performance one way or the other is mandatory.

a "sleeper" is by far the best -- stock on the outside, with some form of monster lurking underneath. done correctly with the total package approach of course, not some made-up mis-matched hackjob directed by -- and/or performed by -- the clueless. there's a night and day difference.

this is for any non-collectible. some that are considered "collectible" is a matter of conjecture. there's probably less "collectibles" worth worrying about in the first place. i suppose of you're an NCRS/NCM type, all C4's are collectible, lol.

bottom line -- mod it, love it, drive it, live it.

 

Let me add that I bought my LT4 stock and have been "upgrading" ever since.To me, the car is better now in every facet than it was when I bought it. Mod on & enjoy.
