If anyone has more info or notices something I've missed, post up and i will try to update this thread.

There are files attached below. Be aware that the 05-06 FSM ECU Pinout may differ in 2013+ year model trucks. Also, the MAPECU3 wiring diagrams for the URD SC are specific to 05-12 and 13-15 year models. No AFR adjust module is required on 13-15 trucks.

Cheers,
Robert

Dude. Nice compilation.

 

Valve train parts from various other Toyota/Lexus roller cam engines should be applicable to the 2TR. Valves come in stainless and titanium, right from Toyota, and they are a bargain. Some later engines have moved to beehive valve springs with their smaller lighter retainers. GSE engines have additional oil jets drilled in the roller rocker bodies to supply extra lube to the rollers and cam lobes.

 

This is very useful. Thanks for posting.

 

OVTune is gonna support the 2nd gen 2TR-FE soon

Excellent compilation of info here!

 

Bravo for this

 

My man, nice work!

 

@tcBob

 

You know I'm in

 

I keep wondering if there is any way to put a Procharger in place of the Rotrex in the URD kit. I keep reading about those Rotrex units locking up and snapping the shaft. They aren't rebuildable, so you're screwed at that point.

 

Anything's possible with enough time and money. The quickest way to start figuring it out would be to look at dimensioned drawings of the Rotrex and Procharger to see if the mounting patterns are even remotely similar and what the difference is for the mounting face to pulley centerline distance. The next obstacle would be to get your hands on of the URD mounting brackets. They don't sell them separately as far as I know, and I've never seen someone parting out an URD SC kit.

 

@BassAckwards The one step colder plugs are Denso IKH22's for anyone with forced induction.

Great compilation of info in one place, I like it!

 

Thanks for the info man! So those would be the same plugs that came with the TRD supercharger in the 4.0 i think.. Will add this to the list for everyone. Appreciate you chiming in

 

The 2TR, xGR roller cam, and xUR series V8, all use the same architecture... for once, the penny pinchers did something good. Too bad a Lexus IS-F cylinder head won't bolt on the 2TR.

 

Looks like the 2TR is finally getting an option for a positive displacement blower

Now that is something I want!

 

I confirmed this weekend that a 31M northstar battery will not fit with the URD S/C intake charge piping. Had to swap back to a 27F Northstar, and it was still a tight fit, but made it work so i could keep my AGM battery. Had to cut up my auxillary fuse panel to fit the oil cooler in there, but got that wrapped up as well. Currently working on figuring out a mount for the rotrex oil cooler, and need to get some hardware for the intercooler mounts, but cut the core support for the intercooler piping.


EDIT: had to go back to a 24F, still didn't have enough room to clear the driver side charge piping.

Heres a pic of clearance after swapping batteries





In other news, got the SPEC clutch and LCE lightweight flywheel in this weekend. It vibrates like a sob right now, so im hoping that will go away once it's broken in. Considering taking the whole assembly out after it's broken in if the vibes dont go away and having a machine shop balance it for me.



Also ordered a type F harness from URD for the MAPECU3 so i dont have to hack up my stock harness. AEM 340 fuel pump and MAPECU3 install is on the list for the end of the year.

170* Motorad thermostat was installed yesterday. I am happy to report that operating temps have gone down about 10 degrees. Normally would be in the 193-199 range, now it's hovering around the low to mid 180s.

 

The Hurst core shifter is available for the R155F as well. https://core-shifters.com/collectio...toyota-tacoma-4wd-w-r155f-5-speed-4-cyl-truck
