No carnage pics yet. She hasn't moved an inch since we rolled her off the trailer that night. I'll take her apart when it's time to put the new short block in.
I did manage to snag a good LQ9 shortblock without a crank for $200 this week. It came out of a running truck with about 200K miles. Seasoned.
Dropped it off at the machinist/engine builder. He's gonna get the deck nice and flat, and bore it up to 4.030.
Mike @ TEC (the builder) had a set of LS7 lifters, trays and oil pump that they pulled out of one of their Mosler road race cars after 60 hrs as part of the maintenance schedule. He builds every engine that goes in a production or race Mosler car. They come stock with a forged LS7 427.
My buddy Dave, that did all the aluminum welding, recently picked up a PT94 for his camaro and found a LQ9 longblock out of a wrecked Escalade for his build. He's going to let me have the crank out of his 98 LS1. That motor just had bad cam bearings.
My other buddy Steve is donating a set of Eagle rods that came out looking new from his old LS7 motor.
My AFR 225's are currently being repaired. I bent a couple of valves and beat up the deck back when I had the LS2 408 on the juice. Never used them with the turbo due to the small 62cc chambers and stock flat top pistons.
Tony Mamo is getting me a good deal on a Comp Cam (he doesn't know it yet
). I want to try out one of those new LSL lobes. I'm thinking 231/231 .624/.624 115+1. I like the look of it on paper for a front mount PT88 370ci build. Open to critique.
I intend to continue to use the FAST90 Intake until it breaks. The boost will be going up over 20 psi. Shooting for high 8's.
The entire first portion of this build was intended to show that with some creativity, good friends, and good buys it is possible to put together a turbo power plant and not break the bank. Seems like the forged bottom end is going to follow the trend. It takes a village to build a race car.

very nice thread, i just read all 24 pages. I love people that do budget builds. I am doing a budget 4.8, yes, a 4.8 build.
However I am putting in a 226/232 cam and going to try to spin it to 7800 or so with katech bolts

This is where I am today. So far a best of 9.57 @ 142 @ 14psi and 18* of timing with the boost jumping around all over the place. WG diaphragm is torn. Ordered a new one today.

It would be nice if I could get a quarter for each view in my paypal ( bellos98@yahoo.com 
). No wonder Google makes so much money.
