Please be a lil more specific....... What is blocking the wastegate? My guess would be your alternator bracket crosses right there. If you have a log mani that is set up like mine I had to customize the stock alt bracked so that it kept its strength and was bolted up the same but was a different shape. I'd show you a picture but I cant link them here at work.

Also yes that big coolant hose that runs off of where the thermostat is can be a problem. You may have to customize that as well. I managed to fit my downpipe in just by it, but i have my downpip protected my exhaust wrap, and the hose itself, to protect it from the heat.

no i am talking about the rear bolt for the external wastegate, trying to put it in from the top it hits the "log" on the mani, from the bottom the head of the bolt will not go completely through, also i cannot fit a nut in the bottom to thread on to, am i supposed the thread all the holes in the manifold?

the coolant hose i will deal with and what size is your downpipe??????

I would ask whoever built your "kit" .... This should have been thought of during R&D...

Yeah, sounds like you got the cheapy ebay log mani, and thats your problem.

You can either
a) thread the hole so that you don't need a nut
b) grind and cut til it fits, then have any holes you made welded shut.
c) try to return it and get a better mani.

The downpipe is pre-fabbed? Who made this kit??

What I did with mine so that didn't happen was weasel the bolts up from the borrom so the nut is on top.
