That part wasn't particularly hard. Since the tangential housing drops the exhaust outlet an inch or two over an on center housing, I cut welds on the bottom where the pipe feeds the flange and angled the flange up to compensate. Some guys have problems with the downpipe being too close to the master cylinder anyway, this will only help with that. Is your pt61 rebuildable? That would still be cheaper than a new one.

No it's shot based on the amt of shaft play I have plus I need more boost lol. You have any pics?

Unfortunately I didn't really take any pictures of the modifications I made. But what I did was mount the crossover and the downpipe, put bolts loosely in the top two holes of the flange to hold the new turbo in place and then just eyeballed how much I needed to turn it up. Once done, remove crossover, cut the bottom and weld it again. I had about a 3/8" gap on the bottom, so i used a scrap chunk of stainless pipe as a spacer. I don't think the 6262 has a 4 bolt housing o ption so you will probably need to convert to Vband.

I wish a had a tig welder that's where my problem lies. What kind of boost is that turbo capable of?
10-24-2018
Get it how you need it and bring it to your local welding shop. A steel supply shop a block down the road did mine for like $30. As far as boost, what do you want to run?

Currently at 15psi but that's everything i can get out of my pt61 I need to be about 20 with no additional timing and have a boost controller that allows me to go to 23 or so when I want more power as long as everything looks good.

Are you sure you have enough wastegate spring? My buddy's car was running 24psi on his pt61.

Yeah it's just because it's on it's last leg the turbine literally rubs the housing with no oil pressure on the needle bearings plus this motors flows very well.

Ouch! I'm thinking of hitting 20 myself on this once I get everything else done. Not sure why you couldn't hit that or higher.Originally Posted by 94GrandPrixSE

Is the turbo you used a T3 .82 vband 6262?
10-26-2018
No, the cartuning kit uses a T4 flange, so I used the T4 .58, it builds boost very quickly, but if you want bigger numbers you might want the .68
10-26-2018
So you just change the on center flange?
10-26-2018
Yup the 4 bolt downpipe flange. Precision uses an off size vband clamp that you can only get from them. Supposedly others will fit okay, but I haven't tried them myself
