Builds Engr 88 Pickup - 22RE Megasquirt turbo build

[EngEngr]

Truck started and ran at -18F today.

KOH always gets my brain thinking about this Toyota '85 axle I picked up earlier and 3link 4link.
That 'can am' on 37s... I think its time to start collecting parts.

85 axle. IFS hubs. 17x9 3.5BS wheels with 37x12.5 tires. 21" frame height
3 link front, 38" lowers and 32" upper, 2.00x12 CO, summit joints, cut whatever I have to for 4" up 8" down
36" Trailing arms with triangulated 4 link rear with 2.5x14 CO

Baby #4 it's a girl!

You guys ever buy parts to spark motivation to work on the project?

I've been eyeing them for a while because the MS2 has such limited analog inputs, so I finally caved and bought a DD EFI Pro digital dash.

Uniclutch and digital dash install coming this spring between diaper changes

Congrats! Since it's number 4 you should have this by now. I've been babysitting my 9 month old granddaughter. Babies were definitely meant for YOUNG people.

Parts are piling up and I need to get some garage time.

 

[aztoyman]

Me too.

 

[EngEngr]

Found some time to start working on this pile of parts.

First on the list is air conditioning, tried to charge it and found leaks. Ended up just refreshing the whole system. Still in progress

Reman R12 Denso compressor and instructions from the 1985 FSM

Evaporator box back in. Waiting for r12 compressor oil and new valves then it will be ready to vacuum leak test and R12 charge. I've thought about wiring a small pusher fan to the condenser and triggering it with the AC compressor switch

Pretty much everything has degraded

I was also playing around with megasquirt idle settings and now have timing adders based on target RPM. I'm curious to see if the compressor kicking on will hold idle speed with the timing advance

I see you have a more modern parallel flow condenser installed. Looks like the one I put on mine. I'm in AZ and I didn't need a condenser fan even with the original serpentine condenser. It couldn't hurt though. May lower your high side pressure. The new style condenser did lower my high side a bit. I don't remember how much. Maybe 10 PSI?? I'd have to go back in my build thread and find what I posted. I'm also running R134A so your system will probably be colder.

Compressor and lines are all in, held -30inHg vacuum overnight. Just waiting on my R12 shipment

Ended up with a new belt and pulley.

AC blowing cold

Still ripping 14 PSI of boost with the AC on. With the hot condenser my MAT is still holding 20F over ambient while cruising. Radiator and fan are holding temps at idle with AC on today while it was 85F out. Fan kicks on at 205, temp peaks at 208 and after ~90 seconds kicks off at 202F.
