GT2871R DBB turbo pics

[DBB mini]

Yeah it's a GT2871R 56 trim compressor, .63AR exhaust hsg, .5AR compressor hsg. I chose it for my 89 turbo caravan project. It's been a long uphill battle too. I had to fabricate a TU header for it to fit the flange of the turbo (exhaust side). It had to be moved closer to the firewall as well. I made a stainless flange @ work & had the boys weld it up for me (@work too). Check out how it swallows the mitsu. Several TD vendors have told me this is too small, but the maps were exactly what I wanted. It was an experiment for me & I wanted 300hp to the wheels, so I took the plunge. I'm only running 14psi @ the moment, easing my way up on the boost & keeping the fuel dialed in. I plan on running 24-30psi in the end with alky injection. I can't believe its only 14psi cause it pulls hard. Spoolup is amazing, pushing plenty of air @ idle. Takes about 30 seconds or so for the compressor to stop after killing the engine from an idle. I'm very happy with it, can't wait to dial in the petro & hit the track.

Great FAB work.... Do you have any pictures of the Mini itself ??? If so, can you post them as well ?

Looks Good

Thanks here's some more pics. I'm a ham. Everything in the driveline is new. Made a double wide IC out of 2 stockers, still need to finish up some brackets. IC sits in front of the relocated radiator, retaining the A/C. Will have new 134 lines. Look closely @ the broken temp guage. Summit honored it with a replacement.

That thing should be like a Super60, better - similar power ranges, but better spool, and better temps.

Yeah it has closer to a S70 compressor wheel, 53mm inducer & 70 mm exducer with a 53mm turbine in the .63AR exhaust housing. It spools like a mitsu but hits real hard. Van has the middle seat in it now so with me we're probably @ or above 3600lbs & I put the 2.70's final drive gears in the A413 & it pulls all that weight without bog @14psi.
