Hey every one i finnaly got ahold of the 60mm throttle body and i must tell every body its huge ! looks good to go... but more inportantaly.. how to swap it all out..

60mm throttle body 1st unbolted the side bolt and took off the liankage

2nd i took out the two little screws inside the throttle body
3rd turned the trottle body to wide open and pull out the brass circle

4th unbolted the TPS sensor..
5th pushed out the 240sx rod..
6th already had apart the 280zxt throttle body
7th put in the stock 280zxt throttle body rod
8th bolted back up the tps making sure it would open right..
9th is were i am stuck at i tried to use the 240sx throttle stoper but its too big
10th i tried to modify the 280zxt throttle stoper but it didint work to well..

i am in need of pictures on how to do the rest as i am stumped at this point..

 

Hello ? has any body else done the 240sx throttle body ? to a 280zx ? any helpful hintz or tricks will help

 

Man... I didn't do any of that. I just took off the throttle linkage ball from the stock TB, and put it on the 60mm TB. I had to take off one of the springs & wind the first spring, half around again to make it work. That was it. I'm lookin through my pics for a good close up.

 

it seemed like the 1996 240sx throttle body bolt was a little bit too big for the stock Tb linkadge ball.. so i thought about it and gave it my best shot...

 

Post some pics of the TB & linkage.

 

I didn't have to change out the throttle shaft either. I used the 240 shaft with the 280 linkage.

 

Nismopick on the stock 240sx throttle postion sesor what wires go were ? i have one black wire silver dotz... 2 white wire ... and 3rf light green wire with red stripe... ?

 

You plug in the stock 280zx harness, to the TPS... thas it. I extended my wires a few inches, to make them fit well. There is also a gray harness, connected by wires... leave it alone.

This really isn't complicated...

 

Hear are a few pictures of what i did... or at least what i thought was right... tell me.. the truth... did i mess up ?

 

Oh... by the way, you did bore out the intake manifold neck, right?

 

nismopick please take a look at my pictures...

 

yeah... you just have the ball 180 degrees off... undo that nut & rotate that bracket 180 (keeping the ball on that same outward side).

 

ok i just did that... do i need any spring auction on that little ball ? just wondering.. also i have a spare intake manafold off my parts car 280zxt.. im going down stairs as we speak and im gonna start boreing that one out... ill take before and after pictures.. give me a few days.. p.s. nismo pick can u send me picture of your 60mm throttle body to see how u did it ? becuase im gonna buy another 240sx throttle body and try it like the way u said..

 

YES... you need a spring on the TB, between the linkage ball, and edge of the TB. Otherwise it won't slam shut when you let off the gas pedal.

I will snap a bunch of pics of my TB, but it won't be until tomorrow (the Z is at my parents house).

 

there's a websight, GRAY'S [DATSUN] GARAGE, has some helpful info on the 60mm throttle body and how to go about putting it on.

hey Bj Bisig can u send me the link for this place ? please im pretty much at wits end..

 

just wundering were did you get the silly idea to swap all the internal parts on the tb?
I would just go get another out of the junk yard, and keep the other one you have for spare parts. but in the other hand the one you have will still work so why waste anymore money you don't have to? I thought about the moter sport one, but I figured go the same rout you did (junk yard). cheep way to go, but the only thing I think is nessesary to change I think is the idle adjustment screw if I am not mistaken corect me if I am rong (probably so).

 

ive tried it the way nismopick but it still doesnt seems right...ill go down and buy another one from the junk yard maybe a 1990 240sx this time.. maybe there is a differance in years ?

 

K... here's 4 shots of my 60mm tb.

 

nismopick what year 240sx did u get yours off of ? becuase im having problems trying to do what u did it seems like the 240sx shaft is way to long for the linkadge..

 

One thing you need to do, is cut that bar holding the springs. Cut it down, just below the ball linkage plate, and keep the first spring on. That way, you can flip the linkage plate 180 degrees to where it should be stock. See attached pic.

 

BTW... if you look at my previous attached pics, you can see that I've done that.

 

I finnaly was able to get it to work.. took a little while and a few altercations but i even got the stock 280zx turbo tps sensor to work.. ill post pictures later i also joined hybridz.com nismo619 is still the name.. hears the link i used to do the 240sx 1996 swap.. http://www.graytechsoftware.com/garage/tbs_linkage.asp

now there are some pictures that reallly helped me out i hope it helps every one else out too ! intake manafold should be on in a few days i got to get to work , Ken

 

Yikes... that's way too complicated. Did you use a die to re-thread the shaft too? I just put on the 280zx linkage plate, cut down that spring rod, and bolted it up. I also kept the 240sx TPS... no need to change it, as it works just as good as the 280zx TPS.
