So the other weekend I go ahead and start putting the set up in and ran into a major problem, The HKS manifold sits so low that the turbo would not fit... not even close... it was hitting the LIM and the frame... and sat too low for my liking in the engine bay.



After a a stress filled night of wondering what I will do I started a WTB thread to look for a manifold that might fit... only one I knew fit was a T88 manifold thanks to SpeedNYC since he ran this turbo a while back. but no luck with anything local and affordable. luckily mobeoner has a collection of crap laying around so I picked one off the floor that we had and the fitment is a 100% better... 




Still need to shave the compressor housing a little bit so there is more than a mm of space from the frame, but it fits in!

While being frustrated with all the issues on putting in the turbo I figured I would do something that has to go smoothly... So I decided to put on my custom plates that came in... Even had issues with that with the screws going on lol. but it got on.




So after finally getting the turbo on the problems as always continue. small issue is the downpipe is not 100% aligning up with exhaust... then again, right now my exhaust is just laying on the braces under the car... and only i think one bracket is holding it up. so small issue... but easily fixed if I need to cut and extend.



Larger issue is the fact that the waste gate does not fit now! which sucks *****... The downpipe is so close to flange there is no way it is fitting on there now. Trying to think of my options...

1- is to try to raise the turbo using a T4 Flange so the DP sits higher. but I don't think it will still clear.

2- make a v-band bend for the wastegate. like a 45degree bend extension to get it to clear the pipe. (will be pricey to make with v-bands and clamps)

3- chop the DP at the top and extend it like 2 inches. so the pipe goes closer to the wall then the manifold/flange! (thinking this might be the cheapest route)






I guess I need to figure out where to put the bung for the wideband... I can make a extension pipe to match up to the midpipe with that on it so I can kill two birds with one stone!
