Yep, I never did get the oil pressure up by cranking but when it finally did start I had instant pressure. I did check the wall clearances after machining and set the ring gaps myself - the Venolia pistons I use are set at a fairly large clearance. Didn't give the cylinders any extra oil before all this cranking - I really think that the fuel washdown was the culprit. When it finally did start, the engine smoked badly from the beginning, even before it had a chance to warm up and expand the rings out to their max size and wear the walls.

Like I said, I'm ready to get this thing going again.

Rick's back. Registered as mojoperf now after difficulty with the old registration.
Finally running. The third set of pistons/rings was the charm, as the ones provided by my stroker kit builder never did work. For this one I took the liberty of installing .260 wall wrist pins as well as Total Seal Steel rings. Still Venolia forged stroker pistons to my calculations/spec, 8.5 compression for use with stock length rods. I don't know if I will ever go E85, as 1. none available within 40 miles 2. Fuel system maintenance looks troublesome, 3.I don't need more power as traction control kicks in lots with 265/35-18 Michelin pilot super sports.
I love this setup! Now with a ported head w/ +1 mm valves, HKS 272 cams, OSGiken triple, and a BW EFR9180.
For the latest startup I filled the oil pump with STP and got instant oil pressure off the starter.
Working on the MS3 Pro tune, all good except for some tricky places in the just off-idle areas, probably difficult due to the cam and big throttle body.
More later, I'm off to a meet.

I'll start over with a build thread with pictures soon.
A priority is getting the fuel gauge to work - almost ran out of gas today. I have installed an IGF simulator, working on a circuit to take the MAP sensor output and scale it to mimic the stock MAF signal.

Belated update:
This car has run me out of money. The stroker motors never did work out -probably because of the piston/ring combos provided by PAECO - after the 3rd unsuccessful rebuild I finally refreshed my original 3.0 GE with turbo pistons and Eagle rods, and put it together with my worked VVTI head, HKS 272 cams, and a BW 9180 EFR. It was crazy fast until my V160 decided to refuse to select gears. I'm done , will be selling the car. I will post in the cars for sale area when I get permissions sorted out. This is a sad time - I love this car, but it has to go.

With the stroker, I never could get the rings to seal - and it seems like there was some issue with block oiling. The ring sealing problem I lay on the pistons that were provided - The block oiling I have no idea. The block had its plugs removed and boiled out at the machine shop - all clearances checked good - maybe some issue with the crank? I have built many engines, and never had problems like this.

Okay, Just wondering. Yeah I have seen oiling issues on motors if the galleries were not right. Also with cranks not drilled properly for oiling. As for rings sealing. Do not know. The only time I have run across that was one of the 5 inch bore race motors. But we got it by changing the roughness of the cylinder and getting it pretty hot. Sorry for you issues.
