DIY Renix Tps On Ho Throttle Body

[jpnjake]

Alright so i’ve been preparing lately to drop an Ho motor in my 89, and so far the hardest thing has been finding a write up on the tps adaptor, the way I have done this modification requires no additional hardware, and uses unmodified Renix tps’s, while keeping the original amount of adjustment.

To start you’ll need to take off the Tps connected to your renix throttle body. Next you will have to remove the arm attached to the throttle (see picture below) 

This can be difficult, I used screwdrivers to work it free, and then flattened the slight bends from removal in a vice. 

I then sized up the Renix arm I had just removed on the Ho Throttle body (where the Ho tps connects) 

I then filed down the shaft on the Ho Throttle body until the Renix arm fit ontop of it. (Note make sure the arm is clocked as shown, other positions will not work)

Then I tack welded it on to confirm it was in the correct location before burning it in completely 

After reaching this point you will need longer bolts and spacers to mount the Renix Tps to the Ho Throttle body. For bolts I found that the Ho map sensor bolts (located on throttle body) work perfectly. (see below) 


Finally For spacers I drilled holes in some 9mm Shell casings I had collected and they ended up being the perfect length without trimming 

(First remove primers by tapping them out, then drill) 

 

Finally bolt It all together and it should look something like this
