Just look at the size of runners and over all size of the stock vs t4 housings..... how can you not be choking an engine to death above 350whp with the stock housing?? sure you can make 400+ but your engine is going to alot more willing and happy to do so without the stock housing regardless if a p-trim or stock hitachi turbine is in it.

But I’m sure most people who have run p trimed high flow Hitachi turbos would agree that the power gains are massive and simplistic when using stock manifold with the internal wastegate. the whp achieved by this setup speaks for it self, if the turbo was really struggling it wouldn’t make the power, the fact that it can shows it can flow enough to do so.
The compressor on this particular t04b we are referring to wouldn’t flow over 350 whp even with the 1.15ar housing. In my opinion using the .84 or 1.00 Hitachi would be ideal and simplistic in this application.

Alright, I am now good and confused. Will or Won't the T04B p-trim wheel fit in a stock s4/5 housing? I never planned to change the turbine wheel. I would like to do this simply, if possible, and finding stock hotside housings is not that hard. If they won't fit I will have to start inquiring about smaller P-trim housings.

It will fit, But the housing needs to be sent to a turbo specialist so the new larger turbine trim can be machined on to the Hitachi housing. Then it will bolt straight up. You will also need to have the wastegate hole machined larger also.

OK, thanks for clearing that up for me. Due to the lack of turbo shops in Southern New Hampshire I am going to have to find a smaller p-tirm housing or make due with what I have.

I have the same turbo, 115 with 60-1, with ported engine (mild), I have the manifold wrapped and the housings ceramic coated and I see good spool around 3g's. I have had no problems. good luck.

Time to talk manifolds. I plan on making (or having one made) a tubular manifold. I have read a few threads that say a longer manifold is better. Is there a optimum length, or can I go as long as possible w/o fitment issues? My brother is a TIG welder by profession, so I just want to figure out the best layout so he can burn it all together once I get the materials. I don't plan on using stainless or anything fancy like that cause money is always an issue.
As far as setup goes, I want to keep the runners divided al the way till the turbo. IIRC this should work well with my divided housing. Another thing I am not sure of is if I should make a Y into one large wastegate, or have two smaller wastegates with a Y after them. Thanks for the help.

Well I just found the thread started by BDC about manifold building. Rice Racing input some great info in there. Given this info I think a long divided manifold with equal length runners and WG runners is the way to go. I think I am going to try and get two WGs to fit so the two exhaust runners are completely divided. We will see how it all wants to fit before I set that in concrete though.
