Default Mods. More trouble than Benefits?

So I am used to modding my cars, had an Rx7 and Supra. Both cars were modded, tuned, raced and never gave any type of trouble. My corvette is my first American sports car. So far i have replaced

- Column lock bypass
- 02 sensors
- Master clutch slave cylinder
-EBCM may need fixing also.

This car has only 16,000 miles. WIth only minor bolt-ons (Headers, intake, catback and diablo) . I would like to continue modding with cams, intake, NOS or Supercharger, but frankly am a bit scared. If this car which is almost stock, and a few problems have aroused, I could imagine what new problems i can add my modding.

I known that when a car is modified, durability and reliabity suffers. But I dont want a 9 second race car. Aim is 400-450 whp. As reliable and safe as possible. WHich mods have you regret? Shouldi just leave as it is?

When it comes to reliability, three factors come into play:
1) Correctly matched components
2) Quality of components
3) Quality of installation/tuning

Give the horsepower range that you seek, there is absolutely no reason why your car cannot be as reliable as stock. Make your choices wisely.

Many of the faults of the C5 are from the factory; no extra charge While modding can push related factory parts beyond their designed limits, that's the case on any car made. Unfortunately, GM is not Honda. They have a well documented number of part failures, and they continue to sell cars with known weaknesses, where Honda would have the offending part redesigned much faster. Accountants, and MBAs took over years ago.

That is precisely one of my car's problem. Headlights take a while and a few tries to go up. It needs viagra . So yes my car does have "aroused" problems

Rx7 and no problems usually don't go together. At least when speaking of 3rd gens with the Twin turbo 13b.

I think the C5 is a very reliable platform as long as you use good parts, and have a good tuner. Mine has been more reliable than any of my nissans or my rx7 ever was.

Find a good shop and do plenty of research and you will be well on your way to reaching your goals. 400-450 rwhp is an easy goal to achieve with good drivabilty and reliability.

They ain't perfect cars. They are sporty cars, they require work. If you know how to do your own work, good, you'll need it. The more you mod, the more you work. I want more HPs too. Stock motor without going FI, is expensive to get more a lot HPs. But what the hell, if you gotta do it, you gotta do it!

I have quite a number of mods and have experienced no reliability problems other then some minor tuning issues. These issue were hot start problems after cam installs which i resolved with computer tuning. Most problems I have experienced with my car came from the factory. EBCM failed, Ignition switch failed and wobbly crank pulley The wobbly crank pulley is a good excuse to pull off the offending part, install a cam and an underdrive pulley.

Ditch the diablo down the line and get a real tune with a cam/head package and you will be at your goal.

I went with a s/c as no other mods will be requires and i'll be a little over 500whp with stock manners.

RX7s have a bad rep. I refreshed mine with good parts, got a good tune 429WHP@15psi, put a big turbo on it, daily drove it, raced it, Never had issues with it. None. Yes it was a third generation twin turbo. I even managed 360whp@15 psi on the stock twins.

Since my engine has only 16,000 miles, opening it to put a cam on it, give me the ****** I don\t want idle issues, hot start problems , cooling problems, etc.... Up to now. The stock LS1 is very bullet proof. I know that this can be corrected with a good tune, and fine craftmanship.

Should I skip the cams and go Supercharger? Is a lot more expensive but engine remains untouch and car behaves relative stock like

Supercharger would be very nice... Like stock until you get into the throttle. You will make more power with just a blower than Heads, Cam and Intake will. Now your thinking in the right direction

The Supercharger will do nothing to affect the drive ability of your car. It literally, will drive like stock, until you give it a little bit of revs and floor it. In my opinion, the transition into boost is the smoothest with a centrifical supercharger as well. I let my 22 year old Mormon girlfriend drive my Procharged C5 last summer without any worries, and it was the first sports car she had ever driven. In my opinion, I would do the supercharger now, then when you get addicted for more power later(which you will), build a forged setup so you can turn the boost up.

The D1 was installed on my Ls1 @ 107k miles 4 years ago this month. I currently have 131k miles now, and the only problem I've had, was a pulley on the supercharger went out(it was a used supercharger kit) two years ago. It's been daily driven, used and abused, and kept coming back for more.

Just a tip — you referenced "cams" multiple times. You only need to buy one cam for our cars. I'd recommend a service manual as well.
