I recently purchased a HKS cast iron manifold to use with my turbonetics 62-1. Did the install but the the turbo seems to be touching the frame and holding alot of strain, anyone experienced this?

 

time to get out the hammer lol

 

trying to avoid exactly that, lol........

 

hey, like you saw in my thread, I had that same issue, in fact I couldn't even get the turbo to bolt on because it was too tight in there. people kept saying it should fit so I thought maybe it was my motor mounts pusshing the motor to the side a little or something. but I went with a different manifold.

but one thing I Was going to try to do is buy a T4 flange and put in in between the turbo and manifold to get it to push up and sit that half inch higher, or a raiser for another inch to try to clear the frame!

hope you can get it to clear somehow without going smashy smashy

 

I did just that with my old OBX manifold, couldnt fit the 1.0 hot side w/o it. 1/2 in flange and some longer bolts and it worked like a dream

 

check your motor mounts they might be bad.. no need for a hammer.

 

my mechanic says its the mounts, looking at himni 2S poluurethane mounts, see if that would solve the problem..........

 

Is that a 1.32A/R exhaust housing. That could explain some of the missing clearance. I'm pretty sure 1.15A/R and 1.0A/R will save you a few precious mm.

If it is bigger than 1.15A/R the housing is probably overkill anyway.

 

i would say motor mounts.....and that does look like a HUGE exhaust side...... i also have the spacer on my setup and made the clearence much more workable

 

1.00 cleared fine (couple MM) when I ran it.

That is much larger than a 1.00

I have since switched to a .84 and gives plenty of room (which is what is in pics).

I also moved up my coolant hard line so that i could clock the turbo almost straight up and down with out interference (you can see i tapped a new bolt hole to mount it higher).

The previous owner did not and I can see it rubbed alot on my compressor housing (probably wore through the coolant line also).

You will want to ensure atleast 1-3mm gap depending on motor mounts.

 

Is this an FD or an FC?

 

The OP has the FD HKS cast manifold and it looks like a FD chasis.

The pics i posted was the FD manifold in a FD chasis.

 

I had the same problem with my HKS manifold. Ended up being shot motor mounts. I went with the 2S Himni Polyurethane Motor Mounts, and now have a good 3" from the frame and turbine housing.
