If a kit could be made i'd be interested in an STS based kit.

Stattama makes a custom intake, they sell it on ZZP'* website. And intense does NOT sell a turbo kit. They were gonna be a dealer for STS, but it never panned out. I was looking at adapting the STS kit to my car, but I had a couple of issues. Number one was the intake for the turbo being under the back of the car, and the number of dusty roads I drive on. I don't trust any filter that much. If that'* not an issue for you, another concern was where to put the piping from the turbo up to the intake. There isn't a whole lot of room for intake piping underneath the car. I was also worried about the oil pump, and the chance of leaking oil from the turbo back to the oil pan.

I think the best place for it besides on top of the tranny like the ZZP and stattama kits is somewhere on the downpipe, so the turbo is still relatively close to the engine. You wouldn't get as much of the cooling effect because of less piping, but the intake could be in the front of the car. I dunno, I'm just kinda babbling, but I say go for it!

Just a few random thoughts on turbos…They are an awesome power adder and are more efficient than superchargers. Hot Rod magazine did a comparison between */c and turbos a few years ago and turbo put out quite a bit more hp at the same boost levels. My 87 t-bird has a basically stock 2.3 motor that puts out around 110hp NA, but was able to push 3700 lbs to a traction-limited 13.65 1/4. And we all know what the GNs are capable of.

But boy, the plumbing for turbos is pretty tough…you’ve got air intake, compressed air outlet, exhaust in, exhaust out, oil in and oil out to deal with. For that reason, I would only attempt to install a kit.

With a factory */C vehicle, you already have boost, so you have to consider if it’* worth the considerable effort and expense to switch to a turbo setup.

I think I saw him post over on 3800Pro as well, and I believe he said there that he was looking at a twin-charged setup?

BTW, if that IS the case, you WILL need an IC under the */C...

Yes that is a definitive. Intercooler required to drop temp at least 100*F cause your intake air charge after the SC will be over 200*F.

I never said anything about a twin supercharger set up. The only thing I am doing is putting an STS Turbo Charging system on my NA Bonny. By mounting the turbo in the rear there is no need for an inter cooler. The distance from the front to rear is supposed to drop the temp by 200-300 deg. I was just trying to figure out if anyone else has tried a similar setup and what kind of results they had. We have put a similar setup on a truck application and had awesome results, but that was a V-8 with a twin setup. Also I am worried about the boost blowing the stock intake manifold so I was trying to find a company that makes a halfway reliable one. I have already ordered the kit last week through my warehouse I am expecting to get it in this coming week. I have been told that the stock intake can handle it so I will try that at first and if not I will order a new one that was mentioned earlier in this forum. As soon as it gets in I will take pics and post them when I am installing it.

Personally if you're going through the expense of putting an STS kit on, I'd at least go with the Stattama intake, then you don't have to worry about the plastic one scattering itself all over the inside of your engine bay.
