To mod or not to mod?

[OVRSTR]

I'm about to open the floodgates...'88 930, all original concourse car in & out with 24K original miles with ALL documentation and records since new. Logic and common sense tell me to leave it alone but some of the posts in this forum are giving me the itch. Should I get into the engine? No exterior mods at all, just the usual exhaust, K27 upgrade and 1 bar boost spring sort of things. I have heard, and read, that ANY non-stock mods to an original car will significantly lower its value but others say that if they're done right, this is not the case. I looked for years before I found this car, I intend on keeping it and I don't want to make a mistake. On the other hand, I've read that fairly simple mods can turn a stock 930 into an absolute beast and apart from women, the more beastly the better right!? Thanks for your opinions.

"MOD" it.

You're not doing any mods that are irreversible so go for it.

Keep the old turbo, exhaust and wastegate spring if originality becomes an issue for you in the future.

BLKBird and I have somewhat rare 89 turbo cabs. We seem to be fine with mods. If your joy is concours competition then you have no choice. If you prefer high speed bug extermination, then mod until your bank screams for mercy. Lastly, these basic mods are reversable. Save the old parts for the next owner if that is a concern.

Just trade cars with me!

Then you could mod it and I would enjoy the 930 as is.

Ha Ha

Now for my real answer...Mod it! Just make sure that all the mods are reversable and you keep the original parts.

OVRSTR,
Mod. it!!
Headers, K-27,1000cfm intercooler,1bar spring,
all bolt on.
You can go inside the motor after your hooked!

OVRSTR, Stop and think about it for a while.
I'm in the same situation myself. A 1980 930 with 50K miles, looks and drives like a dream. The only unoriginal parts are a Momo streering wheel and a high break light "spoiler" at the top of the rear window.

TO MOD OR NOT TO MOD, THAT IS THE QUESTION

I really have the urge to take apart, modify, improve. I think I just have to buy that virtual RSR project car NOW, before I pick the 930 to pieces.

I seached for the perfect 930 for two years. I wanted the best I could find, but age wasn't that important. I was looking at lots of modified , and so called Ruf certfified rebuilds, but I always had a bad gut feeling. The cars that gave me the "buy signal" were always original, uncluttered cars. This tells ME that the originals have most value.

Like you I really enjoy reading about the Pelecanites doing all kind of magic on their cars, and I really admire them for that. Some of these guys are professional, some are close to professionals, and many others do know a "bit" about their cars. They impress me all the time.

Hope this helps you to make your choice.

My 930 is basically stock. It has the K-27, and I have a 1 bar spring (not in right now). Both make huge differences. I also considered H4's a mandatory upgrade. All are reversible. If I were to sell, and the buyer made a stink, I could put it back to stock. Personally, I don't want to drive it stock!

I don't think the loss in value of a 930 with a modified engine necessarily comes from the lack of having the parts to return it to stock. I think the loss in value comes from the impression that a motor with more horsepower is going to have more wear than a stock motor.

Headers, muffler, k27 and intercooler. All are completely reversible so you can refit the stock pieces when you want to sell and sell these items separately if you decide to sell the car.

Don't go with the boost spring. I've had bad experiences with them. Spend the extra on an electronic boost controller if you must have the extra boost.

Go for it...new-style headers will actually lower head-temperature and make it breathe easier. Bigger intercooler will also lower intake-charge temps and make it at least as dependable as it was. Stear clear of 1-bar boost spring and buy yourself electronic boost controller. It's much easier swap, you can always lower boost and you don't need to mess with wastegate or get dirty.

Are you going to drive it or are you just going to look at it?

MOD IT !!!!

you only live once...(I think )

[nostatic]

are you saving it for the next owner?

[RickM]

Nostatic: Best answer I've seen so far.

I realize this will be a repeat of what the others said. Yes, do the mods. I bought mine stock and then did the headers, k27, intercooler changes. I would never go back to stock. And like the others said, you can always put the old parts back on. I don't think keeping the old parts will turn out to be that big a deal. If you plan on driving the car until it has 150,000 miles, I don't think it will be a mint collector car anymore and stock or not won't matter one bit. Also, I think a person could argue that headers and a larger better intercooler would make the car run cooler and last longer. The reduced engine life comes from turning up the boost to fall. All the experts have said that 1 bar is fine, especially if you have a upgraded intercooler. I just don't see the downside to the mods. If resale is your number 1 priority, by a Ferrari and seal it in a bag. If fun is the objective, mod the car. These basic mods dyno'd on my car added 80 hp and dropped the boost to roughly 2400 rpm. A much better car.
