Bored throttle bodies

Recommended Posts

Hello y’all. I think I never mentioned it here but I have been boring out throttle bodies (91 and up) for years. To remove the bottle neck at the bottom of the throttle body (60mm).

 

Last night I successfully made a jig to hold the throttle body so I can bore all way through to 62mm. With the new butter fly plate on.

 

$80 shipped for the 60mm throttle body (core fee of $20 included).

 

$120 shipped for the 62mm throttle body (core return of $20 included).

 

i will start taking orders when the first batch of butterfly plates arrive and they all measure & match up to the prototype I have. 

 

I havent started doing renix TBs yet because I don’t have a core to play around with.

I'd be down for a renix one when you get around to them. I plan on getting a set of battery cables too. :L:

That’s an awesome plan!

I grab every throttle body I find so I have probably eight spares at least and know where to get five or so more.
We can definitely work out some credit for cores type deal.

I have one for 91-92 4.0L ready to go. (Technically it can also be for 91-95 in XJ/YJ platform & 93-95 ZJ platform).

So I bored it to slightly over 60mm and I guess the wall is too thin.

 

Maybe it’s slightly off center   I ll investigate.

 

i managed to finish boring and then grind out the slot on the shaft to accept the bigger plate.

 

ya know those 91+ TBs I have been boring out? The OEM butterfly plates from those fit perfectly.

 

Maybe I should tone it down and bore out to 59.5mm instead and then sand the butterfly plate round the edge.

I'm by no means an expert but it looks to be a hair off center to the lower right bolt hole.
Let me know if you need another.
