Need help on FP3065

[90GSXDan]

Hey guys,
I was wondering something about the FP3065. I know the wastegate is held on by Vclamps for the 44mm wastegate. But I wanna use the 40mm wastegate on it, what process is needed? Do I weld a flange onto the turbine housing?? Information would be greatly appreciated.

Dan,

I am using a 40mm TiAl on my FP housing. FP simply welded a 40mm TiAl WG flange ($25) to the housing before they sent it to be.

The problem is that 40mm flange must “clocked” just right in order for the WG to clear the exhaust manifold. My wasn’t perfect, so I had to spend some time (over an hour) with a die grinder to make it fit. I ended up using an extra gasket to cut down on the porting time.

At that time, I wished that I had bought a 44mm WG . As it can be “clocked” whatever way you want it to be.

I am unclear why you would want to use the 40mm gate as apposed to the 44mm gate? I am too using a fp3065 with a 44mm gate and love it!!

I only used it because that is what I currently had. But it worked just fine with my FP3575. However, I never tried running low boost .

Like I said before, I would recommend going with the 44mm WG.

Probably because he may already have one. If not, I would like to know why as well.

GRNDSM have you ever had any problems with the bolts on the exhaust housing comming out? The little short 1/2" bolts that clamp the CHR to the exhaust housing.

I have had 3 come out on me Doesnt matter if I lock tight them or not, they still seem to back out, I think it has somthing to do with the SS housing? I dunno, but it drives me insane as the last one that fell out was the one that goes through into the exhaust stream, there for a huge exhaust leak right before the turbine.

I had this happen on my old SBR GT-13 once, but that was my fault. GT-13 comes with these little sheet metal plates that need to bent up against the hex bolt head (thus locking them place) . Unfortunately, I overlooked it and they came loose right before a race. I had to pull the turbo and bent them with a screw driver, once I did that, I never had this problem again.

My FP3575 came without those plates. I asked Robert about it and he said that they should stay inside with just the “proper torque”. He was right, I never had this problem resurface. However when I get it back from FP after its rebuild, I am going to see if I can get those plates, just to be sure .

So if you can’t keep them staying in the housing, I would look into those plates.
