1UZ in 1UZ, MAP Sensor, Supercharger The Final Assembly!
Sunday, November 8, 2009 at 8:57PM My 1UZ into my race truck project is coming to a conclusion. The last three weeks have brought completed stepped headers and a rewiring of the entire racer along with the wiring for the new AEM ECU and PCS Trans Controller. A full account and discussion of the build-up and parts selection follows this post further down the page.
The state of the project to date. Some thinngs are complete, but not mounted for the photo.
Nice new headers. We will remove these and check the flanges for flatness, as well as 'seal' the collectors to the tubes to be sure no air is sucked in there which would cause false O2 sensor readings from the collector-mounted sensors (Thanks john.).
-10 fittings for the remote oil filter . . . I have the braided lines.
The location of the new model AEM 3.5 bar MAP sensor.
This is my Tial blow off valve. It currently has a 14 pound spring, way too strong for my supercharger application. I have ordered 3, 4, and 5 pound springs to test . . . so it will idle without surging against the throttle body butterfly.

LATE NIGHT THRASH
One week before start-up and we were up for a late night thrash to get all the final details completed - including grinding flat some incredibly warped header flanges! The other big surprize was discovering that those temp senders (oil, water, and trans) we had so carefully bagged for protection would not fit the standard 1UZ bungs (they are AutoMeter). So, it's off to the machine shop for new ones. The oil pan will have to come off for the oil temp bung.
The plan is to start up the new V-8 on Thursday and tow it to my own track-side shop, then strip test, tune, and trouble shoot on Friday night, before a 'practice race' on Saturday night. If all goes to plan, I will race in an 'invitation-only' fast class bracket race as a part of the Goodyear Racing Nitro Night at Bangkok Drag Avenue on Saturday night the 28th of November. There will be a huge crowd that night as these are the first nitro cars in Thailand ever, and the event has been heavily promoted. Thanks to Goodyear's Richard Fleming for the bringing in The Big Boys!
Many small parts to reinstall, and small problems discovered and rectified. This is the Final Assembly Phase, so everything is clean, neat, tidy, and properly torqued down . . . it's not coming off again!
Talk about burning the midnight oil . . . . .
All the lines and fittings are on site . . . . . . and installed.
A blue race oil filter is worth .07 and 3 miles per hour in the quarter. NOT!
Serviceability is a major concern of mine in race car preparation. You have to be able to get to the parts that need service without having to take anything off the engine. The piping between supercharger and scoop was a major engineering hassle: we had to be sure we would be able to change the spark plugs and route the plug wires without having to remove the scoop. We did.
This is how I left my baby last night . . . along with a list of 19 small jobs . . . . .
