Getting closer on finishing up the mini tub. I will never, ever, do another mini tub again, or turbo build! Who am I kidding? I'm a masochist. Still 100 more miles of small stuff to do...and then the passenger side. Sigh...
Ebay GT45 + 5.9 Magnum + E85 blow thru

Mini tub finished. Putting it all back together now. Hope to finish this weekend.

Thanks I've actually thought of trying some of those. "Back in the seventies" I modded a set of SB Chev headers to fit my 340 Landcruiser. The port spacing is almost exact, you literally can cut off the flange and weld them back up
Back on all four feet...

Looks great, awesome job
Thanks bud! The stance is a little too high in the back for my taste though.im going to move the front spring eye to the top hole and see how it looks. And still need to hang the exhaust.

Sorry I forgot about this. The headers are off of a small block Chevy 350. Like I said they have to be modified with molar flanges.

Did you mount it solid to the frame or with something like this with a isolator, i have a dual one for my bosch pumps.

I wanted to buy one of those clamps but this new pump is too wide, like 72mm in diameter and those Bosch are like 60. So I put together my own mount with aluminum angle and a big hose clamp.

One of the part listers on eBay said and they just might be able to open to the 70mm, but since you made one already, just a thought. Let me know how those pumps work out that thing advertises some good flow numbers.
Since the mini tub, new rear, 3.23s I've made a few blasts from 2nd gear as I log my runs and try to get the Fitech dialed in. The new 380lph pump is holding its own. Car runs straight and feels stable at speed. Through the mufflers the car feels like it's making crazy power and keeps pulling up to 5500 RPM which is my safe max. I've logged as high as 6.5PSI. The sticky MT 295 DRs barely break loose in 2nd and then hook. Can't wait to get this thing to the track!

When in doubt... floor it
You ever going to bring it up to PBIR or what?!
Maybe tomorrow if the weather cooperates. Sent you a PM. Thanks!

What's the highest psi you can run on the fittech?
Documentation says 21psi

Oh okay decent amount, how high you going to take your?
Not very! It's a stock motor. 8 max probably, 10 if I'm feeling really lucky.

Okay but turbos are easier on internals so it should handle 10 easy as long as the tune is good.
I'd be really happy if it all held together at 10 pounds. At 6 it's already a handful! I wish somebody else would build a similar combo so we can compare notes. I think these Ebay GT45s are a unique beast. I've been tempted to try a different turbo but this one spools fast and makes gobs of power with my combo. I'm thinking im close to 500hp now at 6psi and 550 would be easy.

Would be nice to compare, once mines built i can only compare the turbos, mines a much different build.

Which one it is? The 76mm compressor, t4 flange?

Ours is similar, tho you have 42 more “
I had my 318 w/ stock pistons/crank, to 10 psi with a 62mm compressor, .84a/r, non intercooled on E85, headers, 904 and 3.55 gear. Spools by 2500
69mm T4. I think you can still get them on eBay for under $200
