A couple snaps of tonight's progress.
I like this pic with the pistons installed and the old L20 in the background

Head set with .480 lift/.274 Dur cam, performance double valve springs, retainers, and lash pads with a fresh valve job and bead blasted head.

That's a nice cam, should go pretty good

The stripper I used was this,

It worked well in some spots, and others needed a few coats to get the results of that first picture. I'd say the stuff is strong enough if you give it enough time.
I really didn't want to sit with these wheels for the good part of a day to reapply every 15-20 minutes. That, and it makes a mess!

To anybody thinking about using a chemical paint stripper, I'd advise using thick rubber gloves.
This stuff is nasty and ate through the latex gloves I was using. Believe me, you'll know when it gets on your skin!

You get to wrench on parts of your 4door at work? Really? That's pretty cool!...

This in reference to your oil pickup photos with the blue Merc in the background

Get yourself some chemical resistant gloves - you don't want that stuff entering your system...

The engine is almost complete! I was able to test fit the manifolds on the MN47 head without any issue. Surprisingly the MN47 head has both M10 and M12 mounting holes for the intake manifold which makes it very universal. I skipped the step about orienting the timing shaft with the small notch facing forward so when I had the oil pump and distributor installed I popped off the cap and checked the rotor... Sure enough it was 180 out. Easy enough to drop the oil pump and turn the shaft 180.

I've decided to paint the valve cover black to break up all that silver up top and to compliment the silver/black theme I've got going. Another thought I had was to index the plugs which I think I'll do tomorrow. I didn't notice until the pictures how the carbs look dirty mounted against all those fresh parts. When I bought the car one of the first things I did was take apart those carbs and clean them up. They were the cleanest parts on the car back then! Looks like I'll be polishing up these puppies this weekend.

They all have 2 breathers, it's just that the lower one is usually bliocked off for a triple carb installation.

looking good eric!...

that header LOOKS like the aftermarket Z header that Motorsport Auto sells...
But I'm just guessing here...

Eric, your absolutely right. This is the MSA 3-2 ceramic coated header. Should work well with my application. I can't decide between using a 2-1 collector and run a single 2.5" pipe or run with twin (2" or 2.25") pipes all the way back. Any suggestions?

really love what you did... this is one of my dream chassis

i know alot of guys in this thread were looking at the oil pickup info... the diesel maxima pan has an oil return for a turbo... and wings so you can drill an external dipstick. that's how i was going to run my l28et as a front sump.

i still have the pan if anyone wants specs/ or to purchase

:tu:

Spent the morning putting the finishing touches on the engine. Happy to say it's ready to drop in once the engine compartment is complete.
Here's a few pictures of the finished product.

I also removed the brake booster, cleaned it up, and painted it.
I was able to heat the original label and remove it prior to paint, then reattached it.

Looking good Eric!

Now that's some pretty hardware

DeRuX · **Posted:** Sun Jul 08, 2012 6:57 pm

That is looking really good.

Oh don't forget that there is a little 1/4in rubber disc behind the adjustable rod inside the booster. It can fall out inside the can and cause you all kinds of head scratching as to why the pedal is now so long

ImPo · **Posted:** Sun Jul 08, 2012 8:24 pm

Funny thing Kevin, I came close to missing it. When I disassembled the booster it had fallen out of place and I didn't notice it. When I reassembled the booster I found the adjustable rod sitting much deeper than I originally noted. Sure enough that little rubber spacer was floating around within the spring of the booster. I fished it out and applied some grease to the inward side to keep it in position. Thanks for the heads up though! I take it you did some head scratching in the past :lol:

Yes, and since I redid the master cylinder before I'd driven the car, I didn't have any point of reference, and thought that maybe they just came with crappy brakes and that's how it was

Spent some times with the steering gear and linkage. Before and after pictures. Let me tell you this, a wire wheel and heavy steel bristle brush will be your best friend for this!
Surprisingly all of the ball joints are tight and the boots are fresh and free of splits or cracks which means I'll be saving a few hundred bucks on a replacement set. :lol:

(drag link not shown when the cleaning was complete. I'll be painting these pieces black or silver)
