I had a long post with all the mods etc. written out but i'll have to update later,when I change tabs on ipad it wipes out the post I wrote on other tab-arrggh
It was a long ordeal that had me swapping engines/transmissions in/out but finally almost done.
Basically built an L67 and learned ceramic coating,powder coatings as well as alot of build/maching stuff from a buddy.

Most everything is stock (not necessarily from L67 though) but altered/lightened or ceramic/thermal coated.

Stainless headers and modded SC haven't made it onto car yet-using stock SC (no mods) and manifolds (egr welded).
Cam is stock as well,IF I upgrade later plans were only for some rockers so I didn't take it too far (that ship has sailed and sunk already though)

Here's some pics,the thread above is a long one but if your interested than I used it as a reminder of where I was at going back and forth.
I'll update when I get a chance,wanted to get it posted up though in case I need some help I won't need to do a long explanation.

Original L36 3800NA (head gasket blew)

First L67 3800sc

Trans rebuild-100 miles later

Making stuff pretty and functional

Gettin started

All hand polished,ceramic/thermal or powdercoated (not all parts this engine)

Almost complete

I wasn't clear so..
Right now the gold engine is in the car minus the supercharger.
Only have a few miles on it,need to get a tag and hopefully have time today.
No pics of the other stock L67 I put in (three total,2 blew rods).
Gold engine also has NA/L36 pistons/rods so compression is now 9.4:1 with chamber mods I did.

Well so far it has been going great.
Ended up yanking the intake to do some lifter work,might need to yank a valve cover to check a rocker as well again.
Otherwise it's running great.

Only issues i've had with tuning so far is the gear ratio.
These have zero logic to them that I can find,I finally just resorted to trial and error. I'm at 1.02 in 3rd gear now,just need to make another quick change and should have it.

Been logging for VE,started to do the changes manually since I can't get a spreadsheet to work yet.
The MAF will need a bit of tuning as well,the TB has been smoothed,polished and thermal coated and I altered the cross-section where the MAF resides so the calibration is no longer true.

I also need to make a wall to block the hot engine heat from the intake so it pulls from the fender.
My intake temps are pretty high (140+) so that is on the top of list.

is that 140 before or after the blower? i do't remember where the temp sensor is on a L67.

**Playtoy_18** · 06-07-2013

Before...
It is in the rubber elbow a few inches from the TB.

Latest Log (SD/MAF unplugged)

Only seeing a couple degree of knock retard here and there,nothing horrible.
The 140 is driving me crazy,especially since I could drop it even more if she would let me vent/louver the hood.
The thermal coatings raise the efficiency of transfer,so air movement over it would help alot.
I suspect the intake air is actually cooler than the reading,I really want to relocate the temp sensor.
