Hello,

What parts are required for a 2.5L TIII conversion beside the head and manifolds.
I read :
- 2.5L custom pistons,
- intermediate shaft sprocket,
- passenger side mount,

Can I run the stock electronics, will the distributor hit the intake ?
If I use TIII electronic, what parts do I need (harness, ECU flashed, trans sensor) ?

thanks

Some searching shows you can run the distributor if you modify the intake to allow room and do some grinding on the cylinder head.


Or run the distributor off of one of the cams on the rear of the head.

Thanks

Do I really need these parts :
- 2.5L custom pistons (is the compression too low with the stock pistons ?),
- intermediate shaft sprocket,
- passenger side mount,

How about the radiator and upper water nose ?

You need the pistons to clear all four valves. The intermediate sprocket has to be a different diameter and tooth count to accommodate the longer timing belt.

You could probably fab and modify your standard passenger mount to bolt to the correct posititon.

update, I have collected all the parts, but still need to found a way to mount the distributor on the head.
Where to mount it : intake or exhaust camshaft (if that matters) ?

It can mount to either cam. It's really about whichever is better for clearance of your intake piping. Putting it on the exhaust cam maaay interfere with the brake master cylinder. Have you had any luck since your last post?
