So, its been easier than anticipated...
ALL the lines and studs from the CT20 bolted right up on the CT26...
Reclocked the center section, very simple...
Tweaked the oil lines a little bit to line them up, to where they attach to the block...

the old CT20

The NEW CT26

 

Yep, just the charge tube and gasket match of exhaust manifold different.

 

No more of this

NOW we have this

 

Had to cut off the turbo to intake tube...

 

If you cut thru the weld it leaves the flare for the silicone elbow to grab onto, you might get run into issues here with it wanting to blow off.

 

note the bulges between the clamps.

 

Thank you a little late... lol oh well, plan B
If you look close, even if I'd have cut the weld on my pipe it still had no lip to hold a hose clamp on from blowing off... I'm surprised the other end never did its as smooth as a babies butt, somehow never blew off... my turbo may have only been making a couple pounds of boost though...

 

Thanks I cut some thin strips out of some scrap iron and I'm going to tack these to the two ends so the fittings can't blow off... decided to not do this and had the ends flared at ramco muffler shop instead...

 

 

Got my down pipe finished... woohoo
still have to add the O2 sensor

 

That the eBay billet flange?

I still haven't put a bung in my downpipe, exhaust still just running out the wheelwell. Are you going with the Toyota flange style or a screwing bung?

 

the oem flange... the flange was off ebay cnz i think... very nice HEAVY piece... super pleased with it...
my buddy at ramco had a flange for the oem O2 sensor and gave it to me... he's awesome!
ok, i can see that's confusing... the O2 sensor flange IS NOT off ebay...
my exhaust/ wastegate flange is off Ebay...

 

You can see we flared thre downpipe so it's a very open, smooth flow...

 

Mocked up the O2 marked it for clarence.... then hammered a flat spot.... drilled out the hole and ready to weld on...

 

 

There's a oem exhaust bracket that bolts to the bellhousing... i took it off and cut what i needed off for clearance....

 

The hardest part of this whole project was finding a 1982 Supra AFM....

 

Downpipe is ready to bolt on!

 

Got the AFM yesterday... plugged it in...
found #1 5° BFTDC fired right up...
the only clamp. Screw or bolt I didn't tighten was the freakin banjo bolt for the oil supply line...
made a pretty big mess before I noticed I was pumping my oil on the shop floor... tightened it up... filled with oil..
installed boost gauge... fired up... test drive
HOLY CRAP BALLS!!!! WOW! 12lbs boost at WOT and she comes alive... it's really fun to drive...
worth the effort? Definitely...
