I stopped the tuning due to the trans and rear end still being stock

[nismolvr]

nice numbers , real nice

[YamaMX]

Very nice numbers.

Love the Precision turbos, buddy has twin 5857's in his VR-4 and produced some monstrous power.

[ForeignMuscle]

Hell yea for being built in Alabama!

[K_style]

Nice #s indeed. Do you have graph with RPM ?

[silviaNC]

What turbo are you running? Spool time on rpms?

I like the turbo really comes alive after 20psi LOL

Finally! Been following your build on callouts. (one of the goons from no) Nice numbers. But once question, replacing the pistons why not also do some sleeves? Not really familiar with SR motors do the stock sleeves hold up?

+1
Looks like fun man....

I really didn't think about the sleeves till after the work to the block was done...plus from what I understand since I didn't bore the hell out of it the stock sleeves would be good.....guess ill find out LOL

I might start on another block and sleeve it incase something happens to this one.

[boosted27]

I asked for the chat with the rpm's...and was advised that something happened and half the rpm line did'nt show on the chart

dont worry about the sleeves your good

[boosted27]

Decided to take the car out other night and noticed a little smoking coming from the exhaust....after warming up it stopped. While I was out I decided to do some spirited driving....car ran fine did a pull from 3rd gear to 5th, as soon as I let out of it I noticed the car missing and some heavy white smoke.....after getting stopped I popped the hood and there was oil all over the turbo, front cover, and the catch can... the oil pressure was good, and the car didn't run hot so I limped the car home.

I looked the next morning and couldn't locate where the oil was coming from, my only guess is it was coming from the catch can. I decided to check the plugs figureing they would be fouled out...sure enough they were.

When I got to cyl. #3 and took the plug out I noticed the grounding strap was missing, looks like it broke off or melted, didnt see it in the cylinder, went got new plugs and the car still misses.

did a compression test and 1-2-4 are all good cylinder #3 has 0 compression.

[boosted27]

Well dropped the car off yesterday, while I was there we put a scope in cylinder #3.....Seen some nice gouges along the wall, and seen where the side of the piston is ate up pretty good, kind of looks like the ground strap from the spark plug is jammed between the piston and the cylinder wall....won't know the full details till it's tore apart.

[future]

Damn, the numbers looked great too. Hope it is not too bad

[Kingtal0n]

When it happened:
what plugs? what air fuel ratio? what timing advance? what boost pressure? Pump gas?

get pictures of every cylinder, every piston, every plug, every valve, try to also get the cross hatch on the cylinder walls.
figure out why this happened, so it never happens again!

[boosted27]

I was using NGK v-power plugs, a/f's were 11 something, not sure what the timing was, running 18psi, and yes it was on pump gas...

motor won't be torn down till monday or so, when it is ill have some pics taken
