It is a Martin Turbo system made for SBC's. They are no longer being produced and hard to find. The system includes a Quadrajet Carb(tuned for turbo use), a 2 piece aluminum 9lb intake only for turbos, RayJay turbo & heat shield, both exhaust manifolds(drivers side & passenger*turbo* side), crossover pipe(connects both exhaust manifolds), downpipe(connects to the exhaust), plumbing from intake to turbo and from turbo to intake under carb, oil plumbing lines(braided stainless), & a box of bolts and nuts. There are no instructions but it is pretty self explanatory after you start fabbing it up. I dummied it up on a 305 I have on an engine stand in about 20 minutes. You don't have to have special brackets or pulleys like superchargers. The only major bump I saw was running the exhaust, it has to go from the downpipe(above the valve cover* short valve covers are a must for clearance*), between the engine and frame, then down under the car on the passenger side. If you have a descent exhaust shop local, it shouldn't be to hard. The oiling system is simple. Screw a fitting in the back of the block and put the adapter plate between the fuel pump and the block and the oiling system is plumbed.

I was told that I could go as high as 9.5-1 compression and still run it if I used good gas, had a good ignition, and the timing right on. I was thinking between 8.5 to 9.-1. The numbers I came up with on the Desktop Dyno(600+hp on 383 & between 450-500 on 305) were with a generic cam profile and like 7.5-8 lb of boost. So with a custom ground cam and an accurate boost # , the hp could be higher. I haven't used the system, but the guy that I bought it from said that on his stock 70's model 305 Camaro, it went from a 1/4 mile time of 17.1 to 13.4. He said that when he sold the car that he took it off and it had been setting in his garage since.

As for the status of the turbo, I took it to a local shop(This shop happens to have the worlds record for a stock bottom end Syclone of 9.90's in the 1/4), and the main guy looked at it. He said that the impellor had very little endplay and that for street and occasional strip use that it would have plenty of life left. He knows his stuff about turbo's and I trust him. Check out my links page to get to his site(Tobefast). I was also thinking of going thru the carb before using just to be sure that wouldn't be a problem because it was sitting for a couple of years.

I also have a 6lb 2 piece intake, but is is missing one of the pipes that connects the turbo to the intake. A replacement could be fabbed but I was going to use the 9lb and didn't worry about it. One could probably go with the smaller intake to compensate for higher compression but I am not sure. I will include it if the selling price is right. If I keep the 6lb intake manifold, I may try to piece together another system later when funds are better.

I am asking $ 1650 for the whole system shipped, anything less does not include shipping & 6lb intake. These systems sold for around $ 3500 new and are no longer available new. I have seen a couple of these systems here and there(nowhere near as complete) for a little less.

I can get pictures if you would like to see. I can take some of it dummied up on the engine and then spread out on the floor so you can see what all the parts are.

Still available!

 

Do you by any chance know if the manifolds will work on the 3rd gen chassis? Or is this just the universal SBC kit? I'm seriously looking into the Martin system, and almost bought an incomplete kit off EBay recently. I just don't want to spend $1600 and then have to fabricate the manifolds and piping myself I know they made a kit specifically for the 3rd gen cars, but finding one is another story...

 

Hey Marc, it is a universal sbc system. The only thing that I see that might be a problem is if you are using then newer style heads. This system is for the older style heads. I am actually thinking about using this system in my 87 GTA if I don't sell the 2 by summer. I think that the air conditioner box may have to be modified or removed. I didn't find that as a problem, because the air conditioner isn't charged up on mine anyways. I have found a place that sells the non-air conditioner heater boxes. The clearance problems will be with the down pipe going between the valve cover and box. Other than that, I am pretty sure that the manifolds are about like the stock ones. I also think that with a connecting pipe from the down pipe to the stock exhaust, one could use the exhaust on the car.

 

You might have problems with clearance with the oil dipstick on 84-up blocks with the right hand dipstick.

 

im very interested in this if its still forsale
