btw I do not trust those 3 bolt cam gears. I havent touched them but ive heard of them coming loose and slipping out of adjustment. ill probably pick up a better set before I run them.

one day ill have to pull out my head and take pictures of the port job on the head. they didnt really do any work on the exhaust side, and like I said, they didnt touch the opening of the intake ports most of the work was done down near the valves.

the head made 457hp@23lbs of boost on a garret 57 trim t3/t4, stock intake manifold, stock tb, 880cc injectors. tuner stopped there because the car was maxing out the injectors, and im sure the stock intake manifold didnt help.

What fuel/compression/exhaust housing to make 457 on a .57trim?

m4xwellmurd3r

From what I understand the engine was stock compression, an .82 exhaust housing, and im not sure what fuel he was running, possibly e85 since I doubt the crap 91 octane az has would be good to run that much boost on.

I got the head from a buddy that helped build the engine for his friend. He then bought the car from him and started ripping it apart to build it into a full drag car with an ls-v setup

The lobes look just fine to me. Ditch the 3 bolt cam gears and pick up some golden eagle or brian crowers as they use a 12 point bolt head which is much better by design than allen key

m4xwellmurd3r

alright good to know they look fine. the rocker pads seemed ok to and didnt show anything unusual. im definitely going with one of the two options you listed, and had already planned on it when I saw the crap 3 bolt gears.

now I get to measure out for bearings, and send the block to be bored to 81.5

I had a block that I got a good crank out of but the mains are ovaled enough to where oem reds are a touch too tight.

Have it Line bored

m4xwellmurd3r

I will, just costs more than im willing to pay right now since I would have to ship it out of state. No shop in az has a proper line bore machine.

Using the other block saves me over a hundered bucks compared to line boring my ovaled one.
Which will almost cover the cost of buying oem bearings.

So the oval block will be saved for bigger goals. 84 sleeves and more power

(Also the more pictures I take with this phone the more impressed I am with it)

Currently working on a 85mm Ls build would love to go e85 but not readily available to me

why 85mm ? that doesnt leave much for HG seal in between cylinders and you cant go any larger from there if you have a failure or a part

Any Garret turbo guys know a place to ship out my turbo to get re freshened up before I put it on my motor? I just want everything fresh before it goes on..

Im saying Justin, this kid wanted to trade me a sleeved gsr 85.5mm block for my itr head.. I'm like dude really? 85.5 is crazy.. Maybe 84mm or another 84.5 I would have but 85.5 , unless I was going all motor maybe but once you go boost .. You can't go back..

Since this thread gets the most views I figured I'd ask my question here. .

I'm putting together a block for 600+ whp. I'm NOT using plasti-gage to check for tolerances. I recently aquired outside mic set and a dial bore gage both of which read to .0001..

My rod clearance is
.0018 ( R1 ) .0018 ( R2 ) .0019 ( R3 ) .0018 ( R4 )

Main clearance is
.0023 ( M1 ) .0023 ( M2 ) .0025 ( M3 ) .0024 ( M4 ) .0023 (M5 )

I know the rod clearance is righ where I want them, however I usually try to target .0020 for mains. Are my clearances too loose? I already know which direction to take if they are, going to try 5 OEM half shells which I have yet to determine what color ill need. Just curious if .0023-.0025 main clearance is excessive..

Block is at 84.5 right now with scored walls but only paid $200 for the block so why not. Figured o ring it might hold. Read some where he can resleeve a block three times gonna call them and see what's up

In my opinion the mains are too big.

Does anyone know the whp record for stock sleeve ls turbo

I've been researching this bearing tolerance issue and I came across some threads here on H-T that say to use .001 per inch of journal diameter. Going with that formula and 2.1648 main journals would suggest at least a .0021 oil clearance. Is .0003-.0004 over really going to affect oil pressure that greatly?

Really hoping Tepid1 and The Shodan could shine some light on this.

Ball Bearing turbo's can't be rebuilt or resurfaced .. You can only buy new cartridges which are a couple hundred but that's what you sacrifice when you going with a ball bearing turbo that just spools a little bit early.. Going to look into the cartridge and see how much they run for because I don't want precision there junk to me and poorly made compared to a garret..

The mains are a little lose would require a heavy oil. Do you live in cold climate?

jimbo slice

Nope. Tejas. I was thinking it should be fine with a 40w or 50w. This engine is going to live in boost. It's never going to see an easy drive in its life. Guaranteed. Will also be heavily drag raced, shooting for low 10's

So guys i was filling up my track/drag car and wasn't paying attention and accidently put 87 instead of 93.. is that ok, what could it do. . Fmfl last time I feel up both my cars after a long day of work

kicked25th

Got a question for you guys.

Picked up a cheap b20 to replace my previous setup.

Stock it uses the extended tip ZFR spark plugs in a 5 heat range. Im running about 9 lbs of boost, so I know I needed a colder plug.

I picked up a set of the ZFR 6's but they are still giving me some issues.

I know a lot of people like the BKR plugs but I question whether you should get rid of the extended tip design since its what the car uses stock. Also, what effect does the extended have on timing?

Also, like I said, Im running about 9-10lbs(60-1 type turbo), so what plug/gap do most of you use for lower boost setups?

The ZFR 6s came gapped around .044 and I worked them down to .033 and still not getting a quality spark.

On my last setup (LSVTEC) I was running the BKR 7s (I was told to match the plugs to the head) and I think they were too cold because even after dyno tuning and gapping them down to .028 they continued to foul out.

Any help would be greatly appreciated.
