I just learned my lesson so you can all say I told you so. I bought the ssautochrome exhaust manifold and while it might look nice there was serious fitment issues with it. So I am wondering if there is one that would fit my ca motor. I am rebuilding mine and put the ssauto one on and it was hitting everything. It hit the valve cover so we filed it down. It moved the turbo about an inch closer towards the block. Then the turbo knee would have more than likely hit the transmission once engine was reinstalled. So I scrapped the whole SSauto crap and am hoping you guys can help with one that will fit. Any help will be GREATLY appreciated. Thanks

Trust makes a wonderful stainless manifold for the CA. I am not sure it would clear the steering shaft of a LHD 240 though, it's a bottom mount with a long wastegate pipe.

A member on here has got his Trust setup for sale actually. He's got pics of it clearing the steering shaft. It's close, but it clears.

And yes, the runner does get close/touch the valve cover, and yes, it does move it closer to the block, but I've fitted mine with an S15 T28, and although it IS a tight fit, it DOES fit and I didn't have any other clearance problems. did you acually try test fitting the other stuff before you decided to scrap the project?

I ask because I've got at least 3K miles on my SSAC mani w/o a problem yet.

I was just worried about the clearance of the stupid thing and heard some bad stuff about them before. So you SSAC has no problems??? The turbo knee looks like it would get awfully close to the transmission also. I didn't want to risk trying to drop this motor in and having clearance problems. I decided it safer to put the stock one in in hopes of finding one with better fitment. I am just wanting to really drive my car again. My last one had all the bolt on goodies you could get for the CA until I hit a tree at 100mph. I live in Germany!!

There is a used parts place here that has a used Trust manifold on the shelf. Do you want me to give a peek and find out how much they want? It has the triangular mitsubishi flange though.

Sorry about these ?'s. I have been driving the CA powered 200sx for about a year and love it but this is the first time I have had the motor out and actually working on it so please excuse me.

How hard would it be to convert it to the t25 flange. I am guessing just welding it on but I don't know of anybody here that could do a pro job on it. I can weld but cutting something up I just bought and trying to make it work just doesn't suit well with me. If you could help out that would be great. I am trying to keep it kind of stock setup because I am not yet ready for extreme mods to my car. Right now I have 3" stainless exhaust, no cat, 3" downpipe, Apexi intake, HKS BOV, Blitz Access ECU. That is pretty much it right now. I was really wanting to open up the exhaust side of this thing.

Thanks this forum is great you guys are a big help.

You would probably ruin the Trust mani if you tried to put a T2 flange on it. Either get a mitsu turbo to go with the Trust mani, or ge tthe SSAC mani and run a T2 series turbo. I think you can actually run up to a T28 on the stock manifold though.

Like float said I have a Trust turbo kit for sale with everything you need, but i would feel a bit uneasy if you were gonna buy it then cut the flange off and weld a t2 flange on there. In my opinion I think it would be cheaper and safer to get a mani suited to what you wanna run. Anywho here is a link to the thread if you are interested zerothread?id=149428 , like I said it comes with everthing you need name your price and we'll see what we can work out.

Thanks for all your help but I don't want to cut and weld either. I will try the SSAC one more time and see how it goes with it in the car. We finally dropped it in the car today. If I can't get it to work I wil just leave it stock. THANKS FOR ALL THE HELP FELLAS!!!!!

my ssac/t28 combo hits the motor mount bracket. It causes a small gap, 4mm or so, between the exhaust flange and the block... but i can tighten the bolts down with little hastle...

I can get another flange for the CA that is 3/8 thick. Do you think if I sandwich this thing inbetween the head and the mani that this would work? It would push the whole assembly out to about or close to stock placement. So it would go head, gasket, flange, gasket, mani. Torqued down what do you guys think? It might flex a little but just wanted to throw that by you more talented and intelligent people.

if you clearance the runner with a hammer it should fit, mine placed the turbo a bit closer to the block but it made my DP fit better (it was rubbing the frame rail before).

nothing wrong with welding on a new flange, its done all the time. find someone with a tig welder, buy a stainless flange, and it will probably look better than new. the real problem is that the trust setup may barely clear the steering shaft but some other turbo on there may not. and isn't that for external wastegate anyway?

Well I live in Germany and my German is so so, so getting through to somebody about what I need and done might be difficult. I just got the motor back in my new project (The pic I posted was destroyed when I hit a tree at 100mph). I want to get it running smooth then I will try the SSAC one more time. It is great to be part of a forum where people actually help out instead of breaking your balls for not knowing how to do certain things. I appreciate the 240, 200, 180 love here!!!

I wouldn't put the flange in there. I've got an S15 T28 on my SSAC mani and it fits fine. I had to cut off the little stud for the heat sheild, but since I didn't have the heat shield on there anyway, it didn't matter.
