[gsracer]

that you did sir.... that you did.

[GSXRJJordan]

I actually did the exact same thing with my LS6 earlier this year. Wanted to tear it down to get a look at everything, didn't have an excuse to change anything since everything looked perfect. Buttoned it back up with the new heads and did burnouts.

[SicBastard]

"do NOT pull wrenches towards your face!!!!!!!!!"

"Buttoned it back up with the new heads and did burnouts."

Good stuff... Keep it comin.

[gsracer]

so pulled the rest of it apart. Headed to the machine shop tomorrow morning at 6am.

On to the pics

Go the valve covers back from the coaters. Sparkle silver. Should stand out in the engine bay now.






Took all the pistons out.




Went thru the spares of the spares lol for spare parts.




6 bolt main for the pain in the arse disassembly




Empty crankcase.






Now it wasn't dirty by any stretch but i sprayed some degreaser on it so the machine shop guys don't get there hands so dirty.




Some nissan love.




Nice and clean.




Bolted everything back finger tight for the machine shop tomorrow.




ARP sr20det rod bolts direct fit and clevite mains rods and thrust bearings ready to go in.

Nice, hope all goes well

[GSXRJJordan]

Love the pace.

Usually this is one of those things that goes something like:
"going to tear the engine down"
... wait 3 months
"got some parts back from the machine shop"
... wait a month
"started putting it back together"
...

mostly, motivation AND budget dictate a build thread

Yeah what ^^^ said. You move quick, you were talking about going lsX. Then the next day you had the engine pulled and half apart

[gsracer]

thanks I'm pretty obsessive so that helps.

We shall see how long the machine shop takes, they are very reputable and they told me 3-5 business days. I have yet to have any shop local to me ever keep a time table. Thats why I'm driving an 1.5 hr for this one. Time will tell.

I want to have it running by the end of the month.

"Now it wasn't dirty by any stretch but i sprayed some degreaser on it so the machine shop guys don't get there hands so dirty."

At least you tore it down for a good reason LOL.
Great car. One of the builds that has gotten me off my lazy ass to get mine on the road again.

[4-20sx]

Disassembly is easy. Reassembly is alittle more complicated. Love the progress jerry. You def move fast

[gsracer]

Dropped it off at total engine concepts. They do all the work for Titan motorsports and where highly recommended. After talking with them the told me I should go a couple thou looser than the fsm recommends as its not a drag car and drifting/road race engines especially aluminum. Tend to run warmer and they loosen up with heat.

I'm not sure how I feel about that as the fsm dictated some pretty right clearances for "loose".

We did hit a snag though. The rings are gonna take a week or two to get. As everything for this motor. It's not on the shelf.

I'll try to find other things to occupy my time. I wouldn't want to disappoint with the updates. Lol.

You do a good job at keeping your thread updated

[jbballa9876]

Are you checking the bearing clearances and grinding the piston rings yourself or letting the machine shop do that? Im going to have to go through this entire thread to see your goals. Im currently running vh45 but thinking of switching to the Toyota 2uz for the iron block with lots of boost in mind.

[gsracer]

I decided to let them assemble the short block, i will do final assembly. Also the pistons will be calico coated on the skirts to match the factory coating.

Stock clearances are as follows

Main
.0005 - .0012
Limit .0020

Rods
.0008 - .0018
Limit .0026

Being that he recommended the loose side of factory .0012 mains and .0018 rods seems a little tight to me compared to what i ran on SR's for high revving. But maybe an aluminum v8 expands like a mofo. I don't know. What do you guys think.

Goals are a solid 500-550 whp @ 8000 rpm.

[gsracer]

Thanks..... bumping this as id like some more experienced v8 person input on this...

I've been keeping up with this build, very good stuff man. Top notch, fantastic build. Keep up the good work!

[je_decoy]

this is awesome. I was gonna ask how much you wanted for the heads but got even more excited when you decided to go through with this =) . where did you source the bearing sets from all I can find for clevite is rod bearings. thanks for the huge motivation to get me rolling through with my build

[gsracer]

I've had the bearings for a while.

The main bearings are not available anymore and the thrusts are discontinued.

[gsracer]

so I'm really bummed that the car will be down for like 3-4 weeks, plus theres a big event on sunday.

SSSoooo.......

I started thinking i have this spare motor in storage, it had like 150,000 miles when i took it out and it was rough but i wanted to see if it would start so i could throw it in for the weekends events.

To be honest i kinda hoped it hadn't started.... no I'm trying to come up with excuses to not do it lol....

[soreballz]

That's a great idea. Sounds like it's running well.

[gsracer]

ill just leave this here...

The spare for this weekend.

Should blow up in epic fashion.

[PureRush]

Did you cut off your front support? Or do you have it all bolted up?

[gsracer]

its bolted up

[shaggy0778]

Are you sliding at CFRC as well or just countyline?

[gsracer]

if i finish in time I may go to cfrc for frankenslide, if not ill be at KOC sunday.

That would be rad, being that I've never gotten to see this car in person!

[future]

You said your too old for this. But you move too fast to be old
