skib Posted December 5, 2008 Share Posted December 5, 2008 just to add a little, heres my adapted linkage. I used all of the linkage from the ZX throttle body and just did a little trimming SX tb with the Z linkage making the "stopper" had an "arm" here that I cut off ^ (it was the arm that has the hole for the spring in it) and trimmed this "arm" down.^ and of course shaft has been trimmed and re-threaded since it originally has two cable things on it. and the rest slides on as seen in the pics.

Tony D Posted December 6, 2008 Share Posted December 6, 2008 I go with BRAAP on the 'dimples'---they all get removed... though I simply install the injector screws with some loctite blue, or PST567 to seal the threads. I don't use the stock screws, either, for stock mounts they get stainless steel button-head allen screws or SS Standard head Allens. Makes wrenching them tight or loose easy as pie with a dimple-ended Bondhus Allen Key set. For an O-Ring injector setup, the holes get plugged for sure with the SS Button heads and 567PST. It allows 'reversing' to go back to a standard rail and injector setup easier, and the SS doesn't rust and they look cool as heck! Quote Link to comment Share on other sites More sharing options...
iheartz Posted April 13, 2009 Share Posted April 13, 2009 Thanks for sharing pics Im working on the same thing right now, that same site has a nice write up on putting your stock linkage on the the 60mm TB to. http://www.graytechsoftware.com/garage/tbs_linkage.asp what affect does removing the coolant hose from the tb have on performance?

ckolander Posted April 13, 2009 Share Posted April 13, 2009 Just out of curiousity, what year(s) 240sx throttle bodys are compatable for this conversion???? I'm not trying to thread jack, it's just I'm too lazy to search through the eleventy billion threads that 60mm TB's are pulled up when I search.

iheartz Posted April 14, 2009 Share Posted April 14, 2009 im pretty sure any sx tb would do work. as shown in the site posted: http://www.graytechsoftware.com/garage/tbs_linkage.asp the only variation is top or bottom cooled. if i remember correctly, the ka24e is top cooled, and the ka24de is bottom cooled?

iheartz Posted April 15, 2009 Share Posted April 15, 2009 what is being used for the tps? Quote Link to comment Share on other sites More sharing options...
WizardBlack Posted April 18, 2009 Share Posted April 18, 2009 On my N47 head '77 car, I mounted the 240SX throttle directly to the intake manifold. A universal (adjustable) Lokar throttle cable worked quite well. I did NOT need a spacer to make it work, but I used the 240SX TPS with my Megasquirt. The 240SX throttle position sensor is a standard ~0.5V to 5.0V rheostat setup. As an aside, the pictures listed above show the incorrect bit for the job. That is a steel bit, whereas you need an aluminum bit. They have bigger, but fewer flutes. A steady shot of WD40 onto the bit and the work area will make VERY short work of it. Make sure you have a stainless bristle brush. Stop very frequently and run the bristles across the flutes to knock any built up aluminum off (this also works for files). This will keep the grinding bit (which is quite expensive, ~$35) cool and in good condition. Otherwise, you will pack the flutes with aluminum, it doesn't cut and therefore gets hot and blunts the flutes or breaks pieces of them off. Likewise, regarding the bumps on the inside of the runners, I knocked them down and only went through on one. A good set of screws and some teflon thread sealant (or equivalent) will work just fine to keep it from leaking. The other threaded holes in the intake manifold seal well enough with the same thing. As the above poster said, finding good screws that aren't loose makes all the difference. Quote Link to comment Share on other sites More sharing options...
WizardBlack Posted April 18, 2009 Share Posted April 18, 2009 what affect does removing the coolant hose from the tb have on performance? Unless you want perfect manners in very cold weather when it first starts up, just remove them if you are so inclined. My own car is nowhere near that, but I've done the same thing on modern turbo cars that were a daily driver (WRX, EVO, STi, etc.) and never had an issue firing up in freezing weather.

Daphur280 Posted September 17, 2009 Share Posted September 17, 2009 HELP!!! my 280zx throttle linkage arm (the one with the ball) and stopper dont fit over the 240sx tb shaft, is there linkage arm that does fit over the 240sx??? Quote Link to comment Share on other sites More sharing options...
S130Z Posted September 19, 2009 Share Posted September 19, 2009 I'm pretty sure that you have to mod your linkage arm to fit over the shaft. I had to cut mine out a bit for it to work. Don't be scared of using a dremel and getting a little dirty. If it doesnt fit, make it fit. Quote Link to comment Share on other sites More sharing options...
