I doubt you will have the time to get it running when you look at it even if you have all the parts it will take the better part of a day to put them all back on if you know what you are doing. Just check over the condition of the car and take your best educated guess on if it is worth the money.

I like projects and if you are willing to work on it and learn go for it.

That said, I would be very careful about the idea of putting together before buying it. What if, you get it running and then the guy backs out? You've just fixed his car for free. No, if you want it, and don't want the bike, check the car out. Make sure everything else checks out as good as you can. If so, make the deal, and tow the car home, and then you will be working on your car.

But know this, there is a very good chance that there are more demons in this project than meets the eye. Like I said, if the dirt bike has no real value to you, it's a good deal for you, but if this car is crap, and you're gonna miss the bike, it may not be. It's really a roll of the dice. If you're mechanically inclined, and have the time, go for it. But know that it may take alot longer to get it in good driveable condition than you anticipate.

I would also ask your parents what they think. Afterall, they will have to walk through this with you, and believe me, those "I told you so's" will follow you the rest of your life.
I usually don't make posts like this but this x 1000.

Asking how to put this back together is an unreasonable question. There is zero information on what's been added, removed or missing. I think the consensus of the forum, and your pops, is right - this one aint for you. Sure it's not the answer to the question you asked but its the answer to the question you should have asked. Save up for something that's already a runner. Or get this one and have a lawn ornament.

You're young and I completely understand your eagerness to get the car. I'm 27 and vividly remember going through nearly the same thing when I was your age and I still have times now where I am not willing to wait. Trust me just be patient maybe save some up more money or hold out for a better deal. I completely understand you may think this is the greatest opportunity trust me it's not. You did good by asking for advice and many people have given you excellent advice this car just doesn't sound like a good deal for you. I know it's hard but be patient you will get the car you want and there are better deals and cars out there.

That car may cost you $10,000 in a blink of an eye... don't take the bait.
This is not a segment of Fast and Loud's Gas Monkey garage.

Patience grasshopper... you're looking at somebody else's nightmare.

The guy took off all of the parts for the tpi, and has a new intake manifold. I know u just unbolt the manifold since it doesn't have anything hooked up to it yet, but should the original parts just bolt right back in, and also reconnect the electrical parts

Where I come from, we call this "a basic lack of discipline".

I don't have a dog in this fight, but if I were in your shoes, I'd walk away from this 'deal'.

Even the most basic 'cost/benefit analysis' says this is a really bad idea.

My personal opinion, based upon experience: Pass on this car, and if you are really wanting a Corvette, you should be able to find a decent C4 in good running, driveable condition for 4-5K. The amount of time, money, and aggravation that you find yourself getting into with this unknown car might be too much for you to tackle with a limited knowledge-base. I could easily see this becoming one of those projects that never gets completed, eventually sold for less than you have invested. Better you buy a car for just a little more, enjoy it, and potentially be in the Corvette hobby for a lifetime...

Just my opinion...

do you know if all wiring harnes are good and carefully removed.do you see that engine bay,sensors and relais? is instrument cluster still working ?for the hard parts you have to install again intake base with new gasket and rtv sealant on china walls,then you have to instal fuel rail assembly with injectors mounted on,drop the assembly over intake base matching injectors ports,use some vaseline over injectors o-rings,push down fuel rail untill all 8 injectors sit down no their ports,bolt down fuel rail assembly using their 4 bolts,85 uses cold start injector,it goes into its housing driver side, bolt it to the intake base,now go on the runners placing new gasket,there are torx bolts to screw down ,4 of these bolts are bolted from inside.Now on the plenum,again new gasket ,drop the plenum between the runners and bolt it.Now on the throttle body,again put a new gasket and bolt it using the 4 long bolts.Drop the distributor into the engine in the rear of the plenum and bolt it down .Behind the plenum there is a metal pipe to connect ,this pipe goes to the brake booster just behind the rear driver side runner.In front of the intake base you find the fuel metal lines ,bolt these lines to fuel rails ,a bracket with 2 bolts secures these lines to intake base.Now gas cable,cruise cable and TV cable :run TV cable between runners and plenum,gas and cruise cables are routed outside the runners (driver side).this is for the hard parts...

If it was a completely functional car, I wonder why he would consider a switch to carb if he has so many other projects on the go.. I would tend to agree with the majority RUN..

I had asked the guy why he was doing the switch and he said that he didn't want to get beat in a corvette by a mustang gt, or a Honda

Thanks tunedport85inject for explaining the process, do you think this kit would cover all off the stuff I need. http://shop.advanceautoparts.com/web...985%7CL3*15347

I asked the guy if he had messed with any of the electronics and he said he no, he only undid what was there. You cant really take anyone's word on it but now that I have the instructions, I can go up there and put it together and find out. I rather do a little work and either get a great car for a good deal or find out it was a bust versus never knowing what it could have been

I understand what you are going through wanting this car, i bought my 95 when i had turned 17....

My car has now cost me almost ten thousand dollars in repairs and fixing warn parts.

If you wont listen to these guys atleast listen to somebody YOUR age that has gone through the situation already...

do NOT do it, you will regret it... i promise you.

earlier C4's have tons of gremlins.... all of which are very expensive for a car that really is not that quick, youd be better off saving your money and waiting...

thanks everybody for the responses. I think I am going to hold off on this deal, I got to get caught up with all of my other project. The insurance would have been too high anyway, but I am going to save up and eventually get a nice one. Hopefully by then everyone in my are will realize the actual value of their stuff.they always think their **** is worth more than it is so its hard to find any good deals.

Good going young man, I'm proud of you.

When you do score a Vett we will be here to help.

Take care.

I have been on the Forum for 10 years. I have seen several of these same situations. The folks involved spend huge amounts of time fixing problems then the damn car kicks them in the nuts with another problem. This goes on and on until the owner runs out of patience and money. They disappear from the Forum never to be seen again.
There are occasions though where someone with the resources of time, garage space, tools, maturity, patience and money can make a deal like this work.
Take it from one who has paid stupid tax up the arze: Save your money. Work extra jobs. Help others work on their cars to gain knowledge. When you get ready to buy that Vette then shop around. Take a knowledgeable person with you to look it over before you buy one.
Please let some other fool take on this disaster.

Re-installing the TPI is not a simple set of instructions. AND, the reason it was being taken off may not be the TPI. It may be something else ie:ECM. Thinking you can go there and get it running is pretty lofty stuff. I had to replace two bad injectors on an 89 Vette in a parking lot in Daytona Beach two years ago. It took my buddy and I 4 hours and we are both fairly good mechanics but we had NO experience with this type of injection system. We had a Chevy mechanic in Cincinnati on the phone when we needed him to answer questions. If you don't have a person right there with you that knows this system you probably won't get it running. Sorry to give you such good news but you are quite stubborn about this just like I was when I was your age............many moons ago..............JD
