Had a slow leak, so got some new treads. Also picked up some matching painted steel wheels, that i used for the new tires. I had three different style rims ... Chevy, Dodge and I think its a Ford. The Dodge and Ford center holes are bigger.

Drives nice, no more wandering, and ready for snow ... next year

Did my first major pull of the year after my updates to the Intake Plenum, Wh1C with a 14cm housing (8blade compressor / 12blade Turbine), updated oil lines and remote filters.


A-MAZ-ING!! with 2-stage WMI, I actually had to back out quickly as I hit 18psi without blinking...didn't want to go over 15psi. With holding 15psi, was doing 50mph up the Oregon Coastal hills outside of Lincoln City, and never crested 1050egt, coolant stayed at 202deg, and trailer was about 8500lbs. Cruise EGT was between 700-900...mostly held about 62mph


the best this truck has ever done!! was EXTREMELY happy with it. btw, I adjusted the wastegate.. hahaha.


Again, all thanks to the amazing people here!!

Not nessessarily today, but over the weekend...
Replaced two injectors that were showing the beginning signs of failing. #s 3 and 6.

Replaced my ecm with a donor ecm. Installed my f vin chip into said donor ecm. Pulled my oe and it's currently boxed up.

Removed the oe intake and replaced it with the intake from my 85 for now.

Much... much better. I'm leaving for 3 weeks. Im gonna miss my shop.

When I get back...

Steel braided oil cooler lines
Mechanical wastegate, removal of vac pump (it's going to something else), shorter belt, boost gauge and tee fitting.
Gonna make a new intake utilizing a hood-scoop. Want cooler iat(s). Before considering installing the intercooler and wmi. Get it as cool as possible naturally... go from there.

Fun fun.

I'll still be around for the next 3 weeks... just not at my shop. Or home. ... not thrilled about it... oh well.

Please, do tell!

Only sign I know to attribute to injectors need replacing is longer cold starts.

How can you pin it down to specific cylinders?

I installed a new front passenger door handle assembly recently. The driver side handle still needs installed.

I also still have to install all of the rust repair panels after sanding and priming everything. After that's done I can polish the interior plastic which, IMHO, looks awful old and neglected.

Installed Leroy's lift pump harness and pump. Very happy. Great service and great product. Worth the price to save my time. Next is a set of gauges and my walking j ftb kit, when it arrives.

All of the rubber boots are shot, and the grease zerk fittings doesn't want to co-operate with the greasegun.
So the only logical thing to do is to replace everything. I hope I got the correct parts this time since everyone knows rockauto got no idea if any of their parts fits your truck.

I'm looking to do the same job, would it be the same parts list for a 94 blazer, anybody?
