Default One of a kind?

Definately few of a kind...

Built a WRX-style header to fit single port heads. Made it from the ground (flanges) up using 2" mandrel bend on the primaries and 2.5" on the collector. Should flow nicely into the 2.5" up-pipe on the car.

It's not a 100% true mandrel bend anymore since I had to really chop and weld two 90's together to make the tight bend from the passenger side to the collector but I doubt the sharp bend will really affect much in terms of flow.

Nice work! Whats the purpose of it though? To use a stock WRX up pipe, turbo location, and downpipe?

Props! I wanted to do this but I ended swapping to ej22t heads and got to use the dual port turbo manifold. If you could produce this you could be a rich man. There is little to no aftermarket single port exhaust manifolds out there esp for a custom turbo application.

Pretty sure that was his idea since it pretty much is a wrx manifold for a single port application.

Good fab work. I assume you plan to use this on your car?

Oddly enough this is not going on my car. It's what I always wanted to do to my car but had to drive it every day. I also didn't have the turbo crossmember on my car.

A friend of mine has a 2000 2.5RS that he blew his engine and tranny on. It was an automatic. We converted it to manual and I sold him my engine and turbo set-up for cheap along with my JDM WRX ECU and expertise in wiring. I was running 10psi of boost on it with that set-up and the plan remains the same with his. I think it will be faster than my stage 2 tuned WRX.

The best thing is that if he decides to drop in a WRX swap later the car and ECU will already be set for it.

There's a lot of things we are in the process of converting or adding. We have to add the MAF. The TPS plug seems to be different (still unconfirmed). The alternator plug is different. The coil plug is different. The top feed injector plugs were different so I swapped the connectors from the OBS sidefeeds to his harness (the pins easily swap). The coolant temp sensor plug was different. Unfortunately, his old engine has already been sold so we'll have to wait a bit for hime to get his old alt, TPS, and coil back from his friend that bought the engine.

I'll be sure to get him signed up on the boards here and we'll post up the build and pics when were done.

Should sound decent. I had one of my NA UEL headers on it before when I had the up-pipe routed past the CV shaft and it had the boxer rumble. I imagine it will be rumbly.

This is me being a noob, but what are the the advatages of getting a single port head? I've never seen one of those and thus, have never seen a single tube UEL header. Welds and stuff looks great though!
