This is what the turbo kit looks like. Only I don't have the manifold shown in this picture.

As for timing is there a way I can control that with my electronic ignition?

^ don't do that as a feed, its an oil/water cooler. Either t in to the pressure bung or use the front oil galley hole.

For timing, if you keep boost under 7# it might be ok to just run it, maybe a little retarded. Since you won't be able to intercool it, I wouldn't run more than that anyway.

Just put a T on the oil light hole in the main gallery (pictured to the right of your filter) - easy and in the right place.

That's a crazy looking turbo set up. I think you could run an intercooler if you clocked the turbo and ran some really long pipes, no?

I'm curious to see how this works out, as it's relevant to the B20 I have and will be building over the next year or so.

its a draw through setup, so you would be blowing the air/fuel mix into the intercooler, not the best idea.

personally if I were to do a draw through on a 122, I would j-pipe off a dual outlet downpipe, mount the turbo just above were the alt sits, but backward so the downpipe comes out and forward then goes down between the radiator and turbo, and the compressor outlet points at the intake manifold, then find a single SU intake manifold or make a Y pipe on a dual SU intake. Short plumbing, less heat soak, add a water/meth injector pre carb if you decide to run sooper boost, or if its really hot out.

Or with a custom manifold, you could do something like this


hood clearance might be a bit scary, but you could replace the weber with a 2" Jag SU.

I've got a couple of HIF-7's if you're looking for a bit more and don't want to go to an 8 (the Jag guys horde them).

another idea, just need a blow through SU HIF44 off a Mini Metro.

All good ideas.

I was thinking of using a standard Holley with the adapter to do a 5-6 psi draw through setup. I'm not sure if there's enough real estate under the hood for the odd accel turbo sonic setup.

The pics I posted earlier are someone else's. Same kit though. I'm going to get some pics of the kit I'm getting tomorrow. Try to see what turbo is with it.

I'm thinking that if your new exhaust manifold will fit with the stock su intake, that might be a great way to go. You are already going to need a rising rate fuel pressure regulator so adapting a pressure port to the carbs would be as simple as a 1/4 npt barb to the float chamber.

Here are some pictures of the actually setup I found near by while looking at an old muscle car. I'll probably pick it up either way because it's pretty weird and awesome. So even if it doesn't go on the 122 it will find a home somewhere.

That's a Garrett t04b, very nice, looks clean. Make it fit!

Unfortunately it will be a week or so before I can get my hands on it haha. I'm very curious about that intake that says "accel" on it. Also curious to see if that carb adapter has any other features. It's made for an old chevy 350 from what I can gather. Should be more then enough for my little b20!

judging by the pics, the carb mount and the intake compressed air pipe are the same cast unit... so it might need to go on backward if you see what I mean.

I'm not quite getting it. Your saying the intake for the turbo comes from the carb mount? How do you avoid fuel in the air mixture? Maybe you don't?

See more of it do you think I should just use a Holley on this setup instead of trying to run one of the other styles of carb? I would need to fab a custom intake that would match the bottom of that carb adapter.

what I see in the pic is that the carb base and the turbo outlet pipe (that bolts to the intake manifold) are one piece, judging by the turbo placement, it is supposed to sit with the carb centered in the engine bay, and turbo on the driver side with the "accel" logo pointed out front. With the b18/20 having the exhaust and intake on the passenger side, you would need to clock it so that the accel logo is readable from the passenger fender or the passenger seat with the downpipe pointing either at the valve cover, or toward the radiator... make sense?

For the carb, a 4 barrel might be kinda cool, maybe a smallish one.

I gotcha. I was thinking the same thing and trying to figure out how to flip the whole thing to the other side.

I wonder if there's enough space under the hood for all of that? I don't wanna chop things up on this car. I was thinking I could use a webber style intake and just make an adapter to go from the intake to the carb base. But I suppose that would put that who assembly up pretty high so i might run out of room. Custom exhaust Manifold Should be interesting.

I'm thinking a four barrel with vacuum secondaries. That way you could "tune" the additional fuel for when you have built boost. Just a theory mind you haha

Aluminum carb spacer for a Chevy 350 welded to a Webber manifold? Hood clearance might be tough but there is a few inches between the top of the valve cover and the hood.

Yea space is going to be the biggest problem.

well you can just about close the hood with a pabst can sitting on the valve cover so I think you will be ok if you can find or make a very slim air cleaner. The carb mount and spacer should be about as tall as the weber including filter, and you should have 4 maybe 5 inches from there to the hood.

That's an awesome unit of measurement. 1 pbr. Haha

Hopefully I can get all of the stuff in the next few weeks and at least set it under the hood to see what my options are. Exhaust and intake are going to be tough.
