I would hand that 18 year old kid a rock the size of my thumbnail and tell him he can keep the car if he can scratch the every last bit of paint off with the rock!
I'm going to use a micrometer and make sure all the oil ports are the same size as an oem plate I'm going to use the topline plate with the oem pump. I think it will be fine as long as the two are an exact match to an oem plate.
I think the big problem is when people run the bov without the recirculating tube on they don't plug the hole in the intake pipe that is after the maf sensor so thats what causes the AFR to act funky. If you plug the hole and don't use the recirculating tube you shouldn't have any issues with...
Take the internal gate off the turbo then either weld the flapper and run the wastegate on the manifold or get an o2 housing for an external gate and walah you have an externaly wastegated. Then you need to decide wether or not you want it recirculated.
I just bought a mitsu pump without the front plate and I already have a topline complete pump and faceplate. Just wondering if it would be safe to take the topline pump off and use the oem pump on the topline plate?By pump I mean oil pump also.
Why dont you just take a cutting wheel to it? the axle is screwed so who cares about that just don't cut the shit out of the spindle and you would be fine. That's what I would do and I have done just about everything lol.
