I ran into a few problems a couple of days ago.

After a long day of having my 4 year old with me, we got into the car to get ready to come home.

He was sitting in the booster seat in the passenger side, and I had just set the laptop up to get a datalog on the way home. I set it down on the floor board in front of him and while setting it down it somehow made contact with his feet and it shorted something out and screwed up my firmware and fuel map.

I didn't realize it had screwed something up, and we started heading home from my parents' house, and got off of their street and turned right to head into town. Just as we were pulling out of first gear the (screwedup fuel map) caused a backfire and my car started running quite loudly in a big hurry. (it had blown the exhaust off just after the down pipe)

There was a shop rag in the car, I used it as an insulator to grab the exhaust and toss it in the front trunk. (It's only 3 foot long)

I got the exhaust back on, the car ran like crap... I had to reflash the firmware and have been trying to get it tuned back in since.

Last night I did a tuning session out on a farm road (that is paved) I was slowly working my way up through more and more pedal. On one of the runs I hit 16.7 PSI with NO detonation! (IMG:style_emoticons/default/aktion035.gif) (and This was all at less than 70% throttle)

It had the boost, but it was getting too much fuel in the mid-RPM range, so it was a *ahem* slow acceleration.

The ambient air pressure last night was 66.95kPa; and the highest peak of the blue line was 202.8kPa... the math came out to be around 16.7psi.

The purple line is TP(Throttle position) It looks like I need to adjust the TP sensor calibration. (I floor it with the clutch pushed in to burn off any excess fuel from running a rich spot. This takes a split second and gets rid of the fuel that might cause wet walling)

..and the yellow line is the RPM. This graph shows me going from about 0-60ish in first and second gear. The bottom of the slant on the yellow line before the first peak is at 3878 seconds, and the top of the peak after the shift is at 3885 seconds.

I took my wife to the movie tonight. It was a perfect evening for a ride with the top off, we had a baby sitter, so we went to the movie.

We were driving along and heard a 'thunk' under the car, something must have snagged the cooling line or hit it just right to knock it loose enough to cause some damage. It had rubbed a little before and I secured it... but appearantly not enough to keep whatever I ran over from poking a hole in it.

We were almost home when we heard the kerthunk, and I looked under the car to see it peeing. We came right home and parked it, so no overheating, just a big, ugly, green, mess.

I should update this thread...
The coolant leak pictured above was easily repaired once we got the car pulled back to the shop.


In November of 09 I hit a boost spike in the single turbo engine. This caused a minor amount of damage to the seals in the turbo, so it started seeping oil into the intake from the turbo.
This didn't really get noticed until it blew and started dumping oil into the intake and the engine lost oil pressure, taking out something in the bottom end. It now has this clatter in the bottom end. It still propels itself, but rather than drive a knocking smoke cloud generator, it just sits outside as a decoration.
In Sept of 2010 I located a 3000GT VR4 engine from a 95 (it has 4 bolt mains, an internal crank position sensor, two turbos, cam position sensor, and I can easily get 450hp by changing to headers, slightly larger turbos and bigger injectors)
There are a few little bits and pieces I need, and have acquired a few already, including a BOV to avoid pressure spikes.

I'd really like to drive this thing again this summer, so I'm putting all I can into getting my health in order to where I can get back to milling and to where I can rebuild my spare transmission to turn around and sell.

well after lots of personal shit stuff happening that has really screwed with my head and ability to focus, I decided to put together pieces parts that i've been gathering together. It's been great therapy. Driving it again will be even better therapy.


Here's a teaser picture or two.

Dont give up the ship, your still in the R & R stage, shit happens and will continue to happen but it all gets worked out in the end.
I worked through many problems myself and still am, i am close but wont really know for a few hundred miles more. If things dont work.... well, back to the drawing board and try to come up with a better idea.....

I love the 3000gt engine. I had a dodge stealth the first year they came out and later had a 3000gt. Never had a turbo car because they were $ back then.

That will be wicked fast when you get it dialed in.

the problems aren't with the car... (IMG:style_emoticons/default/wink.gif)
R&R stuff and solving issues with the car makes it relaxing and good therapy.

FourBlades: I've been drooling over the MS-III upgrade for my MegaSquirt... dialing it in is goin to be fun. (IMG:style_emoticons/default/smile.gif)

Evil; YES! I knew I was missing a tool while putting that in there.

and last pics for today.

The engine lid and trunk lid both close, and there are a few pics of how much room I have in front of the engine and to the sides. The really wide valve covers just make the engine look like it was super tight fit.

We had the engine and transmission on jackstands and lowered the car down onto it with the hoist.
