2009 Jan edit. I've moved up to a MasterPower T-70 set at 7 psi and am still at $1600, 62# injectors, Walbro fuel pump. . Here is a copy of the new list from post 330 for current parts and prices. And oh yeah, it works all right
2009 March edit: I bought HP tuners.
2009 April edit: I came across a new Holset HX50 for $240 and a friend made a variable A/R valve that I wanted to try so I took the MasterPower off (valve requires a divided housing) and put this stuff on to play with. Turns out the HX50 had the exact same guts as the WH2D, damn. The valve allowed me to turn the boost up double or triple. I settled on 10 psi but the pistons only took that for 3 days. Broke off 2 ring lands. No other damage was done because the pieces stayed put between the rings.
2009 May edit: I now have a forged block, Eagle rods, Wiseco -11cc dish blower pistons, ARP main studs. $1500. I have as much in my block as the turbo project. I love the external gate of the Holset's (sound) but I need to go back to the MasterPower, put a larger A/R on it first, to put the pressure on this forged block.
2009 Sep edit: I bought and installed a .96 A/R exhaust housing for the mp t-70. Its giving me 12-15 psi and 8th times of 7.74@104 off a 2.0 60 ft. on street tires. 580/660 wtq. I'm never going back to the diesel turbo. The Walbro is done...I'm have to run 50% gas and 50% E-85 to keep my AFR up. Working on fittings for an external pump.
2010 Feb edit: Staying with the MP T-70 .96 A/R. I made the external in-line pump, no regulator, no return, controled off a 6 psi boost Hobbs switch. It works but only rasied my fuel pressure from 3 back to 4 bar on 60# injectors. I expected a little more for my $300. I wish I'd have bought a meth kit instead and sprayed E-85 through it.
April 2010 update: I burnt up the 3-4 clutches in the trans boosting #10 in OD. I found a guy that used to own a trans business that works from his own shop now. He got me raybestos stage 1 clutches, extra wide band and drum for $400 and is doing the labor for $400. While the trans is out i put a Fti 2800 stall in also. $800 for the stall and $800 for the trans.
7.1@102 on a 1.7 60' eighth mile
Lockup clutch on the converter stopped working due to an improper chamfer cutting the o-ring. Sent it back for a full refund.
I also made a DIY boost a pump with an 18v DeWalt battery for $20. Worked great.
July 2010: I added a second Walbro inside the tank. This is a cheap easy mod.
Jan 2012: I had my 7th 4l65e failure and am in the process of a 4l80 swap.
August 2019. Been a long time since I've seen this. Car was totalled years ago. 4l80 swap never worked out. 3 drivesshafts never fixed the intolerable vibration. The rear turbo was a complete success and fun to drive but ate 4l65's. I'd like to do my current ride c6 Corvette manual but I don't want it broken all the time
Where the parts came from:
The oil lines are brake lines, inverted flares and hardware from NAPA and AutoZone.
Flo-jet Oil return pump from Tractor supply. I switched to a Walbro fuel pump. Works so far. Quite too. Got clogged and failed. Using what everyone else does now, Surflo...
BOV from eBay.
