the boring but meticulous 2.7i

[modernist]

Got the differential installed. Can't wait to test drive it! I've heard the difference between a 2.93 and 3.73 is extraordinary. Cleaned as much as I could while I was in there, of course.

Got the old diff out. The bolts were totally fused in with rust. If anyone wants it, it's ugly but quiet. 2.93 open. $100 plus shipping

Can't wait to install this 3.73 LSD! Just got the cover back from the sandblaster, got fresh hardware.

Any pro tips?

This thread is great motivation to focus less on modifications, and more on getting it back to showroom cleanliness. Car looks well above par!

Did the Vega pump hack today to replace my dead in-tank pump. Power above 5000 RPM is tangibly improved. Seems peppier overall.

How is your coolant reservoir hose set up?

It's stock.


Installed a fuel pressure damper today ... the one that should be next to the fuel pump was missing and I thought it would be more useful near the fuel rail. Made a little bracket, mounted it under the intake manifold. Low speed drivability and idle are noticeably smoother. Injector noise has also subsided a lot. Whereas before above 2.5k the M20 would start to get really busy, now cruising at 3k+ isn't annoying. Who would have figured.




I've been driving around with the (broken) in-tank pump completely disconnected and my rough cold start symptoms have pretty much disappeared. 3-4 cranks, revs up to 1500 and settles at 1000, like it should. Don't wanna rely on the external pump alone too long (new in-tank is in the mail), but this is really bizarre. Still idles kinda weird, hopefully the new in-tank pump helps.

I had that same issue you had with power delivery.. Would cut off at high rpm and i would have to feather the pedal :/ , got a oem eta pump and problem solved :) . How is your coolant reservoir hose set up? Whereas mine is where it shouldnt be.

Wow looks good.

Nice detailing going on there!

More revvy funtimes :)

OEM eta exhaust, the only differences being a generic cat, and the pinched section under the rear subframe was replaced with a round pipe.

Also discovered that the in-tank fuel pump isn't working at all (although there's battery voltage at the connector) and the fuel pulsation damper is entirely missing. I'll be doing the Chevy Vega pump mod, I'll post pics. I drove across the country twice with a broken fuel pump ... eek! The inline pump must be really strong, doesn't make much noise at all and the car runs fine aside from a weird idle and sometimes inconsistent WOT power delivery.

I have a 3.73 LSD going in soon, just waiting to get the cover back from the sandblaster ...

and I've continued cleaning up the engine bay. The rebuilt AFM from Bavrest works well and looks clean to boot!

What did you use to get it that clean

WD40, a brass bristle brush, and electrical contact cleaner. I replaced some of the badly corroded nuts with new.

Looks good. What did you use to get it that clean

cleaned up the battery junction block today. shiny!

got tired of my leaky halfassed brake booster connections (the elbow fittings that go into the throttle body are MIA) so I decided to do something a little more radical.

tapping the holes ...




test fit ...




after several hours of scrubbing ...




... and installed. that's one huge vacuum leak fixed.





Here is the DIY I wrote. Not sure how many people want to do this, but it's info I would have liked to see.

found a place that sells yellow zinc plated metric fasteners ... not really exciting but I'm a sucker for pretty shiny things
