I got these 1.8s on trade. Like everything else in the engine! HAHA! It is a junkyard build. I put used Diamond pistons in it, even used the rings the guy sent with them! I had a set of new rings to put in it, but the Diamonds use a different ring stack... Didn;t even hone it after the last breakage. The cylinder walls looked ok. I ended up with about .006" clearance, so it'* a little noisy on cold start. It used only half a quart of oil the whole trip including 8 runs. That'* 1300 miles + 2 miles

Awesome!!! I love the fact that you did all this on the stock CAM. I don't plan on changing my cam either, I like my high ratio rockers and good gas mileage.

Well, I didn't get my 11-sec timeslip, only managed a best 12.90 at 116 on street tires! It was hot as hades and the air sucked. It was still 92deg at 10pm! The track wasn't prepped for anything but maybe ice skating. I couldn;t even get it to hook with the slicks on it.

I forgot to post this burnout vid from last May. Put two old tires in the front just for this burnout. The left tire came apart in strips of rubber!

How does one get their 3800 to sound like that lol. I thought a cam would make that sound, but your running a stock cam. It is from the custom exhaust fab work for the turbo.

not all my rubber, we were burning out all day and night, a big private party/car show. there were dozens of cars doing massive burnouts. Even a FWD Honda they had three guys holding it back on the front bumper so it would spin! HAHA!

power logs into custom crossover, thru a T4 1.34a/r turbine housing w/ a GTQ turbine wheel, 4" downpipe, 4" exhaust all the way back and split into two Magnaflow straight-thru mufflers. No resonator, no cat.

Jeff, your Bonneville has always been one of my favorites! I can only wish for 380 WHP with a cammed 3800, but you're doing 425 with a heavier duty trans and with a generally stock longblock + a turbo. Keep on turboing!
