Aaron left to go get a scuba certification but let Greg take the car around the track for a few hot laps. Greg is the one that "blew up" the motor.

How's that?

Basically I think that the majority of damage to the engine was due to plain overheating. It blew the upper radiator hose on the back stretch of lap 7 and that's when I finally stopped, and found the burning plug wire . Pretty much I think the heat resulting from the incredibly lean situation was just too much for a 250k motor. It still runs, but it's tight enough that the starter can barely turn it and it won't idle. I'll tear it down when I get it out and take some pics of the internals for you all. I really think that with some 370's it would have run happily at 12psi, and kicked it good at the track. When I saw the boost beginning to creep I thought "I should pit and fix that", but since I didn't really care about the engine, I just kept it rolling!

Nope, northern front range. About 1 hr north of Denver.

so your gonna part it out now right? :D i wanna have fun with it too. :D cant find anyone around here willin to help me out to try something similar

I am parting it out. My buddy Ed says he may want it, so he has first dibs. If you want, I have another manifold laying around I can do up for you.

I'm in Europe right now, but I'll be home this weekend. I'll get in touch with you after I get home.

Wow that's tough. Dude how do you stand it??? I mean all that sushi and Japanese women I'm surprised that you haven't killed your self yet. Hang in there man maybe you will get to go to Montana one day.

Naw, seriously.. You got to try something else man. I would definitely build the motor to be bulletproof first though. Then you can throw almost whatever you want at it!

The real upcoming project is the J30 track car we're planning. 450whp of VH45 goodness, possibly a z33 6 speed, full suspension, stripped and caged. Full out road race car...

The block:

A cylinder wall:

The head:

So basically, here's the deal.

The KA has gained my respect immensely. This is a 250k mi engine, harshly abused. When I got it the PO had trashed the guides and the chain was in the pan, in like 3 pieces. There are clearly visible marks on the tops of the pistons from contact with open valves. Notwithstanding, this thing held up to some major abuse (12 psi) while road racing with basically 0 management and minor ( FMU only) fuel mods. The head gasket was perfectly intact. There is no evidence whatsoever of detonation in the cylinders. There is very little ridge at the tops of the cylinders, even with the high mileage and the fact that when I got it there was a ton of coolant in the pan due to the timing chain wearing through the cover into the water jacket.

Just thought I'd give you guys a final update on this project. We're doing a major cleaning in the shop today so we figured now was the time to zip it apart and take some pics. The engine will be going in the dumpster shortly... The majority of the turbo setup is still for sale (even as cheap as it is... ).

After about 180k on my motor, I had the same light ridge at the top of my cylinder walls. The best thing about it, was that the factory cross hatch marks in the cylinders were still visible!

Good luck with your future endeavors!

Turbo: T25 should be about $200 in good shape, T28's will be more.

Manifold: Parts to modify approx. $25. I have made a couple for ppl at $125 per.

Downpipe: Approx. $30 depending on exactly how you do it.

Intercooler and piping: Get an eghey kit for approx. $120 and do some minor mods.

Turbo oil lines: $50-$150 depending on your quality standards.

8:1 FMU: Cheap ones are about $100 new, $50-70 use

That should be pretty much it. Wouldn't hurt to throw some colder plugs in, figure $25 for that or so...

Total then is something like $600 if you do the fabricating yourself and get decent oil lines and a new FMU and go with a SR T25.

why?

Sold!!!!!!!!!!!!!
