BTW Los, i'd be really surprised if your car wasn't already making 1000hp on the 8.9 @ 153 pass, isn't your race weight like 3800 - 4000 lbs or something like that? If it's not at 1000hp, it's damn close, so I hope those 120's will handle the new found power you should gain from the bigger exhaust housing.

I'd beg to differ bro, i'd say 950 - 1000 rwhp all day long with 153 mph trap on a vehicle with your raceweight. But regardless, get her going again and see what she does, worst case scenario you keep the boost down until you can upgrade the injectors, not a huge deal.

I hate waiting. I'm coming out of my skin. I was going to try to get the intercooler moved while I wait but the peer pressure is insisting that I wait to do it until I get the motor back together and do it all in one step.

Picking up the motor tomorrow. Should be back on the road by this weekend.
The Improved Racing Oil Pan Baffle System bolted right in without any modification to the pickup or the pan.

Gday mate, very interesting thread. I have a question for you. You mentioned earlier that you would change the position of your turbo if you were t have your time again. I have just purchased a pt 88 for my build, and i was planning on mounting the the turbo on the passenger side{opposite to us} up high behind the headlight. Being that the turbo is mounted more to one side, will the different lengths of merge pipes affect anything? And will the merge pipes still be the same size in od? Also, what power should i limit the stock bottom end too? Cheers and thanks for a great read, and good luck.

Got the motor back and got some numbers from the engine builder.
Bore is still 4.030 (untouched since last build)
Eagle Crank is same 3.622
Pistons come out of the hole .007
The Childs & Albert Rods are 6.125
Wiseco pistons have 25cc dish
Heads were milled to 58cc
LS9 headgaskets are .051 compressed and 4.100 bore
I'm coming up with just under 9.2:1 static. I thought that it would be higher.

I thought that my compression was around 9.1 before. When I pulled the motor out due to the 2 problems I was having (high coolant temp and low hot idle oil pressure), he ended up having to mill the heads down .015 to get them flat which brought the CC's down to 58cc. I think that the larger head gasket bore diameter of the LS9 gaskets helps cushion some of the SCR vs the smaller diameter opening on the 6.0L head gasket.

Gday buddy, ihave anothe rquestion for you. Regarding the ls1 truck manifolds, ive read that i need 02 und up manifolds baecause that havnt egr ports.

If i dont purchase these , i dont know where to purchase the right ones , cheers

May as well post an update.
I got the motor Tuesday night and started working on it Wednesday. When I first built the turbo setup a few years back, I ran into a problem right from the get go with melting the poly motor mounts. At the time, no one made a solid motor mount replacement for the poly mounts. We ended up making a set which turned out to be a bit more difficult than we anticipated due to the offsets and the need for perfect alignment since they have no play. After a great deal of tweaking, we got them on and everything seemed to work right. Problem is that I didn't mark them from side to side and top and bottom. When I dropped off the motor to the builder/machinist, I told him to mark them before he removed them if he did in fact end up having to remove them. Well, I guess that he forgot. So when I got the motor back, the mounts were in a box with the bolts. I took a stab at putting them on the way I thought was correct but once we got the motor up in the car on the kmember with the transmission attached and everything, it was obviously crooked. At that point it was pretty late and I was burnt out and disgusted so I went home and decided to buy a set of professionally made solid mounts that are now readily avialable. Only problem being that I have Steve's (LS2Formula) garage and lift tied up with my car and he really needs it back to but his car back together after the fire from a couple of weeks ago. So I got home at 11:30 PM EST and PM'd Motovative to see if he could overnight me a set. Within 30 min I had a reply and confirmation and they just got here today. Hope to be on the road tomorrow.

LS2Formula has them on his car running 7's. I have no doubts that they work.
She fired up tonight with little effort and strong oil pressure. Tomorrow we verify timing, bleed brakes, check transmission fluid and fill her up with water. Of course it's supposed to rain all weekend but if all goes to plan, she should be stretching her legs tomorrow night.

this might a little late but im looking to get the same turbo and i too am just learning about them. i can get the precision turbo for the list price on the site, but i just want to make sure its the same. do you have the part number by any chance ?
im looking at the ptb700-3025.
sorry for the stupid question and im glad someone like you is willing to take the time to share this stuff with people on the web. i have a small block chev with a 671 blower in my mazda that lays frame right now and i have a lq4 was gonna go with a F2 procharger but the turbo i think is more street tuner friendly

That's very very true. I wont mention the name but I had the worst service through a vendor for 1,500$ in parts a couple months ago. No tracking number, no help over the phone, nothing just order and wait basically. Its a larger company also, ill never order through em again.

Took her out last night for a couple of test drives which were both failures but the next one should be a good one. First time the driveshaft was rubbing on a loop strap for my fuel feed. Caught it quick. Amazing how much the new motor mounts moved ****. Rerouted it and went for another ride. No noises so started to lean on her. POW! Charge pipe blew off the throttle body and hit the radiator clamp and knocked the throttle linkage off. Got that all worked out and should be bringing her home tonight if the weather breaks
