Toyota 20v throttle bodies on B6.
Posted: Mon Mar 08, 2010 7:58 pm
Got my 1.6 up and running today after three months of slowly getting components and assembly work done.
Engine hasn't had its tune yet and requires an airbox to be made up with trumpets.
Just glad the thing ran.
Rebuilt a standard head with new double valve springs, and new lifters.
The cams were sent up to Tighe's and built up and profiled with a 1045 grind whatever that is.
It was suggested to be the right grind for the type of running it gets.
Hillclimbs and sprints.
Cams have 10.7mm of lift which required a fair bit of material to be removed to gets the cams to clear the head.
Next was a gasket kit and a set of throttle bodies off Ebay, which required the fitment of the Mazda TPS which is different to the Toyota one.
Had to modify the throttle cable pull direction as it was setup to pull from the front of the engine.
Manifold required minor trimming to get to fit engine bay of the clubman.
Also swapped loom of Mazda injectors straight onto Toyota injectors so that was a bonus.
Nozzs throttle body adaptor manifold took a while to receive and needed some modification to match up the ports.
Required 2-3mm to be ground out of each port to match both the Toyota and Mazda porting.
Was going to make one but couldn't compete with their price ($225.00 landed).
Made a gasket to suit the throttle bodies as i couldn't find anyone that had one available.
Anyway, the computer needs to tuned to the new throttle bodies and cams.
Computer is a Microtech LT-8.
Engine also has an Fidanza Aluminium flywheel for a bit of increased response, and some modified Jasma extractors (4-2-1).
Looking forward to giving it a run.
