And another one.

I think this one is the turbo I have, it's off an Audi not a Porsche

That makes more sense for a diesel

Well I got it put together and bolted to the car last night, it's a good thing no one told me a 26/24 hybrid was a direct bolt on, we would be having words about now.
Had to grind the crap out of the compressor housing to get it to clear the intake manifold.

I drilled some 1/8" holes in the bottom of the IC tanks to drain out any oil left over. I didn't want to pull it again, it's a pain in the butt having to remove the bumper and all the piping.
Took it for a 25 mile drive to just get all the oil blown out of the IC, was only hitting 10 psi.
I had the waste gate @ factory settings and the 2 hole sin the IC compounded the problem. I put some screws in the holes and tightned the WG down.

I think I'm going to T into the line going to the WG and run a line in the car with a bleed screw, install a boost gauge on the exhaust manifold as well so I can get the drive pressures set as close to 1:1 as I can.

Head to Nevada here in a min so if I make it back with the turbo still spinning i'll post u.

I'll get some pics of the destroyed k24 as well when I return.

zukgod1 ,

So we are blasting down the freeway about 250 miles from home and the car looses power instantly! We go from 80 to 55 and in my mind I'm swearing up a storm saying "I should have just gone T3", anyway I limp it off the exit which was about 1/2 miles away watching the rear view for blue smoke that never came thank goodness, stopped under a over pass as it was at least 100deg outside. Popped the hood and BAM!!!! I didn't tighten one of the IC clamps enough and it had blown off. Dodged a bullet there. Still have another 300 mile run home so hope she just keeps going.

So what have you noticed in the 1st 250 miles as far as boost and power go in cmparison to your old setup? Earlier, later, different shift points etc?

To be honest I can't tell a difference. Seems to spool about the same, maybe just a tad slower. I can't get more than 20psi out of it but I haven't really been trying either. I noticed my EGTs seem to get higher going up long inclines. I'm kinda thinking maybe the tubing I used for the air filter maybe be to small and possibly restricting the intake some. The inlet on the 26 is smaller so I wasn't able to use the OE intake boot. I used some of the left one 2" IC tubing I had.

I think when I get home I'll see about making a larger intake and use if that will help.

Well we made it home. Other than the scare when the IC boot blew nothing exciting to report.

To be honest I'm kinda bummed about this "upgrade". It spool's a little slower and I can't tell a difference at all on the EGT's or power.
Seems to me if anything they (EGT's) are a tad higher, this may be due to using the 24 housing and machining it for the 26 wheel making it smaller inside and increasing back pressure.
I'm going to get another boost gauge to check driver pressures as a reference. This will tell me if I have to much back pressure due to the small housing.

I changed the intake last night to the OE intake just had to make a bushing to get it to fit but that didn't help.
Right now the WG doesn't even have a boost reference tube going to it.
20psi is max and I'm still getting allot of smoke in the upper RPM's.

I still don't think I'm getting enough air..

I've played with the waste gate till I got sick of it.
I just dont think I'm going ot be happy with this set up.

my car has gone through several t3's... so until i do a gt20 or gt25 or maybe a vnt... this latest t3 i have the boost turned wayyy down.. i'd rather drive it slow and weak than not at all. and it's a summer car only.

I hear ya, I've done the same.. 20 psi max and no fast shifts causing it to bark... Not as much fun to drive but as you mentioned it's better than not driving it at all.
