My '90 RT Minime swap

Band Wagon
So, my wifes RT died just on the outskirts of town on th estrt of a road trip (lucky to be near home) and I had it towed home. I started investigating hoping it would be a main relay or something, but nope - the t-belt was torn up. Then I started tearing it apart...
The pistons looked good, and there was no discernable damage to the A6 head, but...... I had always wanted to do a minime, and the A6 had 195kmi on it. I bought all the maintenance stuff (H2O pump, tensioner, gaskets, etc...) and found a nice '00 Y8 vtec head on ebay with 85kmi on it (it had a AEM adj cam gear as well
nice) for $170 shipped to my door.
Here's the pile of old A6 stuff
It took about 3 weeks all said and done, but most of that was waiting for parts (oem stuff took the longest really :roll: )
then
oh yeah, I painted the valve cover with some high temp ceramic-in-a-can engine paint - and the exhaust heat sheild too...
oooooooh, sideways shot (see AEM gear)
I wired vtec with a rpm switch/relay - set to a 4800rpm changeover. I also had to retard the cam gear 4deg to get TDC right on - then I added another -2 to that to spruce up the bottom end a bit more (non dyno tested, but butt dyno approved).
She runs great and get 2-3mpg more than when it was stock - mo powa is good, although not a TON of umph but more than it had - especially in the 3-4,00rpm range, which is excellent for climbing mnt passes. We rally this car up over 12,000ft passes almost every weekend and it does better than I could expect
Nice shot post ripping through the neighborhood with my son Ian, plowing snow, and lovin it!!! we had a TON over the holidays here around Denver. Dunlop Graspic's on stock wheels. I have del sol 14" 5-stars for summer.

I really like the valve cover too - it turned out better than I though it would. The repainted exhaust heat shield really makes th engine bay look clean too (old finish was worked over).
I'm trying to find a local dyno that has a emulator and can tune the PM6 with turboedit or the like to get all the power/efficiency I can out of the setup. Then maybe a cam later..... and more dyno time. all in due time.
And yeah, the snow is kickin so far this year. We just rode Winter Park on Tues and had a killer day - have season passes there so it's at least once a week we go. Snowing as I type
lucky bastard :twisted:
