First time poster, i apologize that i do not have a current build thread to share with the community beyond what is shown on my personal instagram. IG handle is my Ih8mud forum user name.
Firstly let me say that the truck in question is a 1976 Toyota pickup(Chinook) that has received a 1kz-te heart transplant and a r151 tranny/tcase behind it. built by Big Country Customs in Abbotsford, British Columbia
After the completion of this build and about 8000 miles i have noted a few areas that need improvements and i am hoping the community can offer some new eyes to existing problems.
1. Cooling issues
I overheat pulling hills or on hot days normal driving
- Running a 2.5" exhaust with free flowing muffler from turbo back (custom dump pipe as well)
- inter-cooled
-Large radiator with two front mounted fans
(my notes of improvement are as follows, remove inter-cooler to increase room behind rad, add rear mount rad fans (no room for mechanical) possibly do hood scoop with top mount inter-cooler. Not a lot of airflow through the front of the truck)
2. rattle/engine miss/intermittent smoking on warmup/ low rev chatter/hesitation
smokes on fire up with evident timing issues, warming up and driving stops this but under decompression or little throttle there is still evident timing issues. under load and in boost no visible issues
- 170km roughly on motor, a/t ECU
- fresh head, new cam
- EGR deleted
- Rebuilt injectors
- fresh valve adjustment
- new glow plugs
(my notes for improvement are as follows, purchasing a mechanical pump(found) changing the truck from an electronic to mechanical 1Kz-T under the impression that my pump is causing my timing issues and Upping boost (to help climb hills and keep airflow up for connected cooling issues) )
