Returning to this project. Since the last update the following was done:
- Installed a new OEM rubber intake hose
- Replaced A/C tensioner pulley with new OEM
- Been driving it to break in the engine. Still running on non-synthetic for the remainder of oil change. Then I will switch over to synthetic.
Engine has been running well. Though the RPM does settle out to 450rpm when warmed up. It runs really smooth at this RPM. I have looked into the following with no change in idle RPM.
- IAC valve. I cleaned it and verified operation per manual.
- Inspected and checked the TPS per manual. Within specifications.
- Replaced aftermarket intake hose with new oem. no change.
- Inspected all vacuum hoses. They were all replaced with new during rebuild. Vacuum valves were also replaced with new during build.
- Timing is set to 3° BTDC.
I have left to test the EGR valve and solenoid. Any other ideas? Maybe the accuracy of gauge is not so sharp after 300k miles.
In addition to the above, I purchased a partial new gen 3 supercharger from
@Convoy. It is missing a few items that I am going to try and fabricate and/or locate with whatever free time I have. If you have any parts sitting around please message me!
What I have:
-New supercharger and plenum
-crankshaft pulley and spacer
What is missing:
-throttle body adapter. Fabricated February 2022
-bypass valve and solenoid. Obtained.
-intake runner pipe. Designed.
-brake booster pipe
-coolant pipe
-belt tensioner bracket and pulley spacer. Fabricated December 2021
-assorted hoses, nuts, and bolts. Obtained.
So far I have started to work on designing the tensioner bracket and spacer. I have tried to send my design to a few of the online shops like hubs.com and oshcut.com for bending but they come back with a note saying the press would not be able to achieve this part due to how close each bend is. CNC is the next option. I can have it made as an assembly or two separate parts. Anyone have a press that can do close bends?
The second part to be modified is the orange clutch fan. I have purchased a new one from Toyota and machined the flange down to fit the water pump nipple.
The next part I will be working on is the throttle body adapter. I may design it as a multi piece part for easier machining. If anyone has this part to assist with measurements that would be great.
If anyone has any of the missing parts please reach out.
Orange fan clutch machining.
Belt tensioner bracket and pulley spacer. I think CNC might be best option.
