Throttle body upgrade

Featured Replies

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,

"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"

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

Like a K&N cold air system, also what about the AFM, can I just leave that or is there a way to adjust it. Keep in mind I have to pass smog over here :ermm:

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
