turbo/intercooler plumbing

[vr4_3000]

I have seen numerous pictures and posts of alot of 420A motors with the compressor housing turned up and the flange is sitting at about a 45 degree angle. Is there a reason no flips it around and uses a spacer with longer studs to give it the extra clearance? The only issue I see when you flip it is that without a spacer you will hit the crossover pipe behind the compressor housing. I have searched and have hit a big halt on this project. suggestions?

Hahns I/C setup has the compressor outlet aimed towards the valve cover, a 90* coupler connects it to pipe that leads to the FMIC. Both the inlet and the outlet are on the same side (drivers side).
Most people that do their I/C pipes custom point the compressor outlet down, kinda gets rid of clutter. Most people that do this also have a FMIC with the inlet on the passenger side and outlet on the driver side.
It's mostly determined by preference and whether you by it premade or get it done custom.

I will have to post up some pics of what I am doing. I come from 4G64/63 tech. Things are so much easier there. I am building a guys 420A motor for him.

Thats because you are trying to add parts to a car that wasnt designed to have them. Of course it is easier to change out turbos/intercoolers on a car that came with them.

actually i have a 4G64........

Then your in the wrong section.

read the full thread. I am working on a 420A and am looking for some other options. I own a 4G64.

Maybe you should clarify your posts a little more then...
And I have read the whole thread considering I'm the one who answered your question. If you have another question ask it, don't make stupid posts like "I have a 4g64"; no one cares and it's totally unrelated.

ok... So are you asking why some 420A guys don't flip the compressor side pointing down? I have mine pointed down and I don't have a spacer. If I had a spacer I'd have to remove my radiator fans, which I obviously want to keep. You can point it either up or down, but down is makes it a lot cleaner as rstare already suggested. Basically this job will be all custom made.. Cutting and welding will be most likely need to be done with the use of couplers (if you want to use couplers I have my whole IC piping welded). Either by you or a shop. I'm not sure if that answered any of your questions because I didn't really get what you were trying to ask for... So I gave you that. Good luck.

Oh and please be specific on what you're asking. It will help us to better help you and provide better information as well. Thanks.

OP - There is already very little room to work with on 420a when it comes to turbo. Like PCD said, if we were to add a spacer the radiator fans become even more of an issue than they already are.

My apologies. That was a drunken post. The biggest issue I am Having is that there is this oversized front mount he wants put on for a 16g in which I was going to remove both fans and put 2 slimline fans in. I have taken out all his emissions and A/C. But that did not give me enough room for the exhaust to clear the starter with a 2" spacer. So now i have to put it the same way I have seen every one elses. Is anyone else running a front mount with opposing In/Out? Have pics?

I am, but I do not have any pictures readily available. My inlet is on the passenger side, and the piping come off the turbo to the passenger side, above the IC and down to the passenger side inlet. *The inlet is curved upwards*

A reason why some people (Hahn included) don't point their turbo outlets down is because it interferes with the internal wastegate actuator mounting. I had an external wastegate setup on my car so I was able to point the turbo outlet down and made IC piping routing a lot easier for a FMIC.

Bingo. When I had an internal wastegate setup there was no way I could point my compressor down (my setup was 100% custom).
