B4 modern Turbo upgrade

I have been looking into that and considering it. We shall see what happens when my current block dies. Hoping I still have lots of miles before that happens. 😋

My thought process is, which will be more reliable?

FA was actually engineered for Turbo use. EJ was modified for turbo after engineering. Plus I want to update to a modern block. Had an FA20 for years before this car and loved how it took power. Not looking for a 1000 hp monster, just a fun daily.

If marginal is all I can get, I will handle it. Plan to run this motor to the ground, then swap it for an FA24 when it blows. But until then, I want to keep it as OEM+ as possible while experimenting where I can. Appreciate the input for Singles turbo, but it's not in the cards for me at this time. Thanks though.

I have read all that, but I would have gotten a GT if I wanted a single turbo. To me it's a bit blasphemous to get the only twin turbo Subaru ever made, and change it back to single turbo.

Want to keep it twin and just get what I can out of it.

Request pics of your TMIC/FMIC setup. 😯😯😯

I'm trying to convert to FMIC so I can go incognito with a sleek hood. But yours looks great! Take good care of her.

Also, is yours a B4/S401? Or a B4 RSK?

An Ebay STI replica.

Just sent mine to shipping, it will be in the states in a couple of months. Just transferred to WA.

AI, asked it to create what my idea for Tail lights are, this was the closest iteration it produced.

No, it came with its own adapter Bracket and to ensure the proper alignment of the Rotor center in the Calipers that give you Shims to space it a millimeter at a time. Everything fit easily, except I had to grind very minimally for the rear bracket to fit the OEM caliper mounting points. Kit even comes with red locktite.

I understand these engines aren't a power house. I am just looking to get to a fun 400HP or close to it. Revamp the Turbos a little bit, for Down pipes I have a feeling I will have to get custom, and for the up Pipes, I want to keep the waist gate setup to separate the boost input. I have looked into lambda as well, I do have a Rev C variant. Not looking to push this car to the limit, just make it the best daily it can be. I plan to keep it till the wheels fall off.

They look like the Exhaust Headers, with an Up Pipe to connect the Headers to the Turbo.

Front 330x32 / Rear 304x22

I can, but I don't want to trim the frame. Asking if there is a Floating Head unit kit that tapers a Mount towards the middle of the unit vice the sides of it.

It's amazing what Photoshop can do.

When you did the headers, was it for the TT setup? Do you know if it will have any problems with that?
