I recently purchased a 80mm Universal Throttle Body, one that required a Q45 TPS.

I was unhappy with this as Q45 TPS sell for $150 and the documentation on loom changes is limited.

I had a look at the TB and noticed a removable spigot on the shaft, this spigot engages the gear in the Q45 TPS. After removing it there is the shaft with a flat surface for a grub screw to mate on.

I made up a cam to sit on this shaft and cut a slot to engage the paddle driven RB25DET TPS.

Care needs to be taken when cutting the slot, you want to engage the TPS is its resting position to give you room for adjustment.

The machining could be much better but i only had a bench drill and some files.

      Exhaust silencers/varex exhausts

      By PotatoCake · Posted

      Yeh... literally every time i jump on a forum, see an instagram post or see an engine bay at a car show, i get an idea and add it to my 'to do' list. So what started off as, hey can u just make a couple of intake hard pipes because my dumbass bought the wrong apexi kit, blew out into a 2 week job including braided brake lines & custom bash kit for the front lip haha.  Getting Luke from A4E engineering to make a full custom exhaust with a controllable aes dump valve so i can actually switch between quiet and loud, because right now its just loud all day every day. Then after that go and get the tune redone flex e85 & 98 as i get bugger all milage from e85, makes going for longer drivers difficult

      Car looks clean as. You ended up getting quite a bit done 😂  So what's the plan for the exhaust?

      Rb25det vs Rb25de rods and crank are same?

      By GTSBoy · Posted

      The only Neo rods that were any different to any other RB25 rods were the DET ones, and they were the same as RB26. Here is a Neo DET rod. O5U part number visible. Here is a post in a thread here on SAU with evidence from someone who has done this before. There are photos in the thread of normal RB25 rods.

      Magnetic Drain Plug Snapped in Half

      By joshuaho96 · Posted

      Sure, but why assume that will be the case forever? And why assume you'll be able to do an oil change to swap back to a stock drain bolt before that happens? And does it even matter when I change the oil at fairly short intervals? Life can be funny sometimes and unexpected things can happen. Like breaking a collarbone so you can't do any work on your car for a few months but the oil change is due so you have to take it to somewhere and hope they don't do something stupid like stacking the new drain plug washer on top of the old one.
