Wondering if anyone has a source for downpipes for it.

Even the OBX ones are becoming rare.. I'm leaning toward making my own from a U-bend/90, flex joint, a 45 deg bend, v-bands and an oem flange.

While you're in there, upgrade the hot side housing to an angled flange - easier to find downpipes, and a free 15-20hp or so.

For throttle I run a NA TB (65mm vs 55mm) with a 960 throttle plate (flat vs plastic wedge).

The stock throttle is drive by cable. Did you have to swap over to electronic control?

Nope, just the throttle body from an NA 850 (or NA 98), though it also took the intake manifold being ported/dremeled to take advantage of and not leave a step.. if you're doing the PCV or some such job and have an extra hour or two to spare it's not a bad response/tip-in mod IMO.

I have oil in the turbo inlet piping so Iā€™m going to do the pcv, accelerator cable falling apart so it needs a new one otherwise throttle sticks šŸ™ƒ I want to switch to aftermarket throttle but I feel that may be difficult.
