That looks like the ssauto wastegate....

[jt15833]

what manifold?

[themadscientist]

HKS wastegate. The turbo looks genuine Garrett too but the manifold does look Ebay-ish.

[teddy]

looks like an SSauto top mount kit to me. They sell the 40mm hks replica wastegate, manifold and that dump pipe as a bundle. Although I have heard that their wastegates actually work well(gasp)

[top_secret]

it is the XS top mount and wastegate, but the gate is being swapped for an HKS one my friend has ASAP, the clearance around the diaphragm/piston thing is more than ideal, I don't think its going to help that giant turbo spool up one bit. But yeah I got the package, I got it for even less than their ebay auctions by calling them directly, even if I don't use the wastegate I can resell it, I may end up trying it out just to see how it works, it’s a clone of the HKS one I am swapping it for so it shouldn’t be a big deal to switch them out later.

The turbo is a garrett T04e that came with a one off HKS turbo kit for a customer in japan. the manifold was trick, but bottom mount (RHD only) and cracked to hell and back anyway. Coudln't find any other top mount manifolds for the CA to accomodate a T04 flange turbo. Its ok though it looks like it will be 100 times easier to put on/take off than the tubular bottom mount I have now, and I have several friends handy with welders so if it cracks I'll just have it welded up.

I'm more worried about it fitting under the hood, at its highest point the turbo is around 7" taller than the top stud on the exhaust manifold, so I'll have to see how that plays out.

I only have 450cc injectors and a Z32 mafs so fuel will probably be the limiting factor in the setup but I’m hoping to reach high 200’s at the rear wheels once I get the turbo, injectors, mafs, tuned ECU, AVCR, and front mount in and tuned. If everything is working correctly I may upgrade to 550’s or 600’s and an SAFC in the future but for now I’m just concentrating on getting what I have tuned to the most out of what I have (not sure I want to turn up the heat on the stock long block more than 300 on pump gas anyway).

you'll need a to hire a migdet to get in there and hold up that turbo, that mniafold will NOT hold that up on its own, those SSAC things crack easily, and that turbo is very ehavy, get some brackets and a flex pipe for your turbo -> downpipe, good luck bro.. and can i say slloooooowwwww ssppooooooooooollllll biiiiiggggg pooooowwwweeeerrrr!!!!

[top_secret]

I don't buy into the whole flex pipe argument, there wasn't one stock. The most important thing is to get the downpipe securely fastened to the transmission crossmember so the manifold doesn't bear the weight of the exhaust, since there are no other hangers forward of the rear section.. The turbo I have does weigh a lot, but not that much more than the stock T25. When I get my DP welded I may weld some extra braces in there as well...or I may just leave it stock and if it cracks, send it back.

also the midget idea won't work, that would burn his hands.

You will be sorry if you don't start buying into the whole flex pipe thing. You think that stuff is going to stay still when your engine starts moving? If you think so, I wish you the best of luck. And BTW, the SSautocrap wastegate works just as good as the HKS one (If not better).

yeah but youre FWD, its a bit different.

[boost_boy]

Dude, I have done this swap too may times on RWD and FWD alike. If you care to put your turbo system at risk for shock which will create cracks and unwanted vibration, it's your choice. I'm only giving it to you from experience.

I know a lot of people with all sorts of swaps in their 240s and I don't know anyone with a flexpipe. Its weight that causes the cracking, a flex pipe weighs even more than standard tubing so it would probably just make it worse. The exhaust mounts are designed to absorb the motion of the motor, thats why there is no stock flex pipe.

[c-rad]

If you use the brace on the downpipe that attaches to the transmission, you do not need the flex pipe. This way, the motor, turbo, transmission and downpipe all move as one unit.

[top_secret]

yes I agree 100%. I ran a tubular manifold without the downpipe to transmission mount and it cracked right away...a flex pipe would only be necessary if you secured the exhaust to the CHASSIS and not to the power train. or if it was laterally mounted.

[CA19DET]

i have one thing to show you:



i have had a top mount T3/T4E on a 18g mild steel manifold, that cracked so many times, i cant even remember..

i am talking from experience and first hand knowledge on top mounts, i have seen this exact style SSAC manifold in peices already on honda and SR applications..

do what you want, dont post here when it cracks and destroys your turbo..

[top_secret]

how would a cracked manifold destroy a turbo?

dude I run an SSAC manifold

[themadscientist]

welding slag or other debris being released into the turbo when the manifold lets go or in some outragepus cases turbo falls off.

[top_secret]

thats extremely unlikely...

[boost_boy]

thats extremely unlikely...

Then you've already made up your mind, so go for it. All of the resident experts on this swap have spoken and yet you have a solution for everything that was said, so I'm going to lock this thread since you don't really need our advice.
