I was just wondering if a 1990 240SX KA24E Throttle Body will work on a 1978 280z and if it does what kinds of things will I have to do. I know I have to grind down the manifold and get a spacer but what other things will I have to do. Thanks

This might work for you,

http://www.arizonazcar.com/inject.html

"1 inch aluminum throttle body spacer to adapt the LARGER 240SX butterfly onto the 1975-1983 Datsun 280Z, 280ZX stock EFI manifold. Includes the longer bolts required. Can be drilled for additional injector, available in red anodized or plain aluminum

$36 each"

Thanks for the help. I was getting one off of ebay and was just checking to see that it will work. I will keep you guys up to date when I get it, I will probably need some help with it. Thanks alot

You might want to consider upgrading some other things, as you only get improved performance ( if that's you goal) through equal intake and exhaust.

That means if you are using a bigger TB for more flow, your intake (air cleaner stuff) and exhaust should be bigger(if necessary) to match.

thx

Also what about the throttle position sensor, can I just use the stock one instead of getting one for a 240sx. The throttle body I got from ebay doesnt have one. Thanks in advance
