Awesome I have been looking for something like this.

After a hard run I can place my hand directly behind it (where the dip stick and heater core hoses are) and feel fine while my upper arm and face feel like it's melding.

sweet, only you would do something this cool man
cant wait to see dyno diff. b/w this set up and old one...i suspect faster spool and 7% in power across the entire band

why do you expect faster spool and 7% power increase? :hustler:

Damn good work. As always.

What i like is that, by my math, you put out 15 lb/min at redline through the exhaust...so about 7.5 lb/min each....the 1544's efficiency max was at 6.3 lb/min, the 1548's are at 8 lb/min....so they should make better hp per psi.

they do look physically bigger in there...how long before two 2056s?

The exhaust sides (x2) should flow around the 2560's, while the compreser flows...a lot. I'm a little worried it my flow too much.

Now that the manifold has T2 flanges, all that needs to be redone is the downpipe. Unfortuantely that's the hardest part. With these turbos the downpipe covered one bolt hole so we had to drill a hole and weld a tube thru the downpipe and use a ~3" long bolt.

I should have layed the 2871 in there to see if it fit. ;)

Hmm. I think slower spool, and I hope for more than 7%.

If spool is too slow I can always turn the anti lag back on ;)

:hustler: pretty much lol
a little guesstimategage :jerkit:

glad to see you are doing it again. what can i say it takes lots of skill to attempt something like this. Great job.:bowrofl:

I'm extremely happy to see this setup still exists and is finally in a running vehicle, I believe with the 4th owner. The lower half/Y-portion of the downpipe went missing somewhere along the way (the piece that was the biggest bitch to make), and the cold-side Y-pipe was trimmed a bunch, but the current owner made it work and it lives!

Yes, 10+ year bump bitches.

The last time I saw this for sale it had made it to the west coast. Does the new owner wanoto reveal themselves?

I always thought this was a cool setup. A little impractical maybe, but a neat project one the less. :likecat:

m2cupcar 06-15-2018 10:33 AM

Surely more practical than a turbo KL V6 swap? :bigtu:

andyfloyd 06-15-2018 11:19 AM

Always loved that setup Tim, make another one!! LOL

narval314 06-15-2018 07:14 PM

Heya! I'm the "new" owner!

I actually obtained this setup I think 7 or 8 years ago. Back then I was trying to install it in my '94, but since I had no idea what I was doing and was a poor college student, I never finished it. Last summer, I decided to pick up a '99 and try again.

I only have a rough street tune at the moment and haven't been to a dyno so I have no idea what kind of power it's making, but I'm sitting at 14 psi and it's a blast to drive!

This looks awesome! How do you think it'd do with a different set of turbos? I've got two gt2052s that I'd had given to me, and they both work fine, and I think it'd be a pretty cool build!
