I am running this through my head and I cant come up with anything, other than the intercooler that may cause interference.

I have a 1966 mustang with no shock towers. Engine is a 331 and the trans is an AOD. I am wondering if a foxchassis TT kit will bolt right in?? I imagine I might have to have to do a little tweeking on the downpipe and maybe some brackets for the intercooler, but...what else?

Any opinions?

If its the right price i would go for it, I have a custom Fox body single tubo kit that will be the donor for my 68. I woul imagin with all the added room the changes would be rather suttle in comparision to fabbing up something from scratch or trying to work with the shock towers.

Depending on the amount of tweeking required, you might consider building your own kit.

If you do buy a fox body kit, the cold side will be useless and will need to be redone from scratch.

What about the fueling system? Fox body kit will be for EFI, is your engine fuel injected?

You may want to send 10secgoal a PM, he has started developing turbo kits for classics... as far as I know, he's been going with a single turbo tho.

It will probably fit. But like mentioned, the cold side would be useless, and who knows where the turbo would actually be located. Lets forget I make a kit for them, why would you not look into a kit made for the specific car ? Are you looking at ebay stuff ?

you need to find a way to intercool them and also make them for efi... then you got the market. I think there should be an intercooler regarless of boost levels just to be safe... also, efi responds better. I would venture off to say most people willing to turbo their car will already be running efi motors.

EFI would be easy, and probably cheaper. But I think he's got the right idea by starting with a hotside only kit until he builds up more of a clientel and reputation in the community. The hotside is the hardest part of building your own kit. Coldside is easy so long as you have room for an intercooler and don't need it pretty (can be done with misc bends, a hacksaw, silicone adapters, and t-bolt clamps).

If you can't fab up your own coldside, and can't afford to have someone do a custom job for you then there's a good chance you shouldn't be messing with a turbocharger in the 1st place. The general rule of thumb is that most turbo mustangs spend more time on jackstands than they do on the road.

Very true... I just think the majority of people wanting a turbo kit want to buy something and install it though. Fabricating takes a while and some people just dont have the tools to do it or the skills to make it look decent. I personally love to fab stuff up and will build my own kit if I ever get around to it (actually..next project is a cummins diesel model a pickup that I will have to make the whole kit) but for people like my friends...they just want something to bolt on and be done. Thats why full kits including fuel systems are so popular. I really think that is why the turbo classics are not as well known as supercharged setups.

A full kit is expensive but when you dont have to mess with anything, convenience is going to be cheaper for most people than hours upon hours of fabrication.

I really thought of doing what 10sec was doing before he wanted to...I wanted to build kits and sell them.. The reason I said it was a bad idea (and the reason I think no one has a business like ProTurbo Kits) is because these old cars have way to many different engines...different pulley setups, different convenience options (power steering/ a/c), efi or carb...there are just to many variables to meet the demands of everyone. If you look at the threads in the past, there has been lots of interest in the kits but everyone wants a kit that fits their setup...which is different from the next guy.

I think he should focus on a EFI 302 based kit that retains power steering. 302 is probably the most common motor I see in cars, efi conversions are a dime a dozen these days, and most likely the people that like to mod their cars for efi would be the people wanting a turbo kit. Even if it wasnt efi, the only difference is the cold side from the intercooler to the intake. If he planned it right, it could be the matter of extending a pipe and being done for both kits. Also, intercoolers should be included in the kits. While they might not be needed in his opinion, the market of people who dont know everything about turbo setups see every car around with an intercooler. People dont have to know what it does but they know it should have one. Front mounts are so common with any turbo car whether it be a ricer or a diesel truck. People are scared of what they do not know and to see most cars have them and he has a a kit that doesnt have one...they would probably worry.

His ebay auction a while back had to many maybes about it. Cant run this or that, its might fit with this or that... Its a complex world with a classic due to all the variables. Foxbody and up cars all basically run the same motor for 5-6 years and people roll with the stock motor... When you can build 1 kit that fits 79-93 cars with a stock 5.0 and its efi setup, you have something worth mass producing.

Very good point.

Plus.. who knows what's been done to the car in the last 40 years. Most of our classic's engine bays look alot different than they did the day they came off the assembly line.

unfortunately... Again, Id make a 302 efi based kit with everything needed and see if it sells. Then if he needs, just change the intercooler to intake pipe and you have a blow thru carb setup. I actually started a thread on another website asking of people would buy an intercoolerless kit and the majority said yes if it was REALLY cheap and they would add their own. They also said that they would want an intercooler for expansion reasons...able to run more boost on the same setup without changing much. If he can get one to fit on a 65-66 then he should be able to run the same kit for the 67-69 years. The frame rails and crossmember are all the same. If he could do a long intercooler that mounts behind the front valance, it should basically be interchageable between 65-70.

(i think I made a couple words up)

I don't take any offense to this, so don't take it any such way. The only reason I don't offer an intercooler for a 67-68 is because it just won't fit(nothing WORTH putting there). And I don't have a 69-70. 65-66 may get A/A, but have found something better without cutting holes.
The new kit does fit with P/S AND A/C. But it took more bends to do, and that means less hp apples to apples.
Most guys don't have EFI in these cars. Most are like me and want cheap and to the point. The clients are building now with 65-66 headers. I should have just done the early years first. Plain and simple. Evertime I went to sell a kit, I was asked if it fit 65-66.
Have you looked real close at these cars? You can't put an intercooler behind the valances.
And I think the ONLY reason that super chargers are more popular is nobody knows they exist. So nobody goes looking on ebay for them, or looking for them at all. They look for blowers and nitrous. Because that is all that has existed.
EFI could be done in this car. But then you have to cut a hole in the apron to turn the turbo side ways. That is the only chance you have on getting the DP out. You have to do this because you can't put in on the other side with all the acc people want to run. The Dp has to run this way because now you have to run the coldside where the DP was supposed to go. I just think are 10 times the amount of people that have carbs in these cars than EFI. And if you have EFI and want one, just PM me. :)
With all the chances made and variables sometimes people are just change if they want it. You didn't want to do it because of all the variables. I've only required a battery relocation and crossflow radiator this time. I think that's pretty good, considering also that is what most performance oriented people have now anyways.

P.S. The only reason I only sell the hotside is I'm basically the boogey man on the internet right now. An ENTIRE kit is alot of money to send to somebody without them being well known. I can sell it all.

Wow, thanks for all of the replies. I was on a mini-vacation and just had a chance to read them all.

I guess I can throw the fox TT kit out. I wasnt looking at anything on Ebay in particular. I did see those $900 Twin Turbo kits....lol.

I am just trying to get my powder adder figured out. I am having a hard time deciding between a 671, or the paxton kit, or even a custom turbo setup.

The price for the 671 and paxton kit are about the same @ $3500-$4000 when it is all said and done. I believe, however, that the 671 out of the hood might not be street legal because it might be considered that it is obstructing my view. The paxton kit I can get a good deal on through one of our club sponsors, but I will also need to spend an extra $200 on an intake.

Now, the single turbo kit would be great....especially if I could use the paxton box around the carb...I just like the way it looks. However, finding a turbo kit for a classic, carb'd mustang is not the easiest task.

Any ideas? Opinions?

10secgoals kit or you will have to have a guy fab up a kit for you... Id personally go turbo but the expenses will drag you away from the idea.

I can do the box for sure, just send it to me. Biggest problem would be if you wanted anything else. I won't push, but a bonnet could be clocked it the other side. Say if an IC was used. I don't know if a box can be. May want to ask them...

A little thread resurrection happening here...

Seems like i've heard of guys putting the intercoolers in the wheel wells - is that a possibility, given there's no room behind the valance? I could be way off course here though. I noticed in a new TT 2005 GT drag car they were running the intercoolers in the passenger seat. Of course that's not an option for a daily driver, but just trying to think creatively here...

Any news (10secgoal) on where to put an IC? Anyone done it without extensive mods?
