2s2mad Posted August 25, 2010 Share Posted August 25, 2010 Hello, I am looking for a throttle body upgrade for my slightly modified 280Z. It will run a ported and polished head, MS fuel only management, turbo injectors and header with bigger exhaust system. So I am looking for something with a TPS sensor and that would be bolt-on on the stock intake manifold and throttle linkage. Thanks Quote Link to comment Share on other sites More sharing options...

Challenger Posted August 25, 2010 Share Posted August 25, 2010 (edited) The TPS in the picture looks like a stock one. You need a 240sx TPS. To be honest, If your looking for performance you might as well save your money for something else. If just for the clean look of the 240sx TB, go for it.

2s2mad Posted August 25, 2010 Author Share Posted August 25, 2010 You are saying that I should look for something else than a 240SX throttle body? You are correct it's a stock 280Z TPS. Since I am getting more fuel, I thought the 240SX Throttle body was the way to go to get more air? Thanks Quote Link to comment Share on other sites More sharing options...
Challenger Posted August 25, 2010 Share Posted August 25, 2010 If you think about it, your runners and ports will only flow so much air. Just like water in a hose it will only flow as much as the highest restriction will. Quote Link to comment Share on other sites More sharing options...
aplyedmind Posted August 25, 2010 Share Posted August 25, 2010 challenger is right there is no need to upgrade your throttle body. You could just port your runners .....Or do both throttle and runners . But I don't think the stock ecu will like u much after that Quote Link to comment Share on other sites More sharing options...
Challenger Posted August 25, 2010 Share Posted August 25, 2010 Also I think the stock cablep pulley on the 240sx Tb is made to where the throttle opening doesnt open at a linear rate. I dont have one to look at but If I recall from when I had one the first small section of pulling the cable opens it slowly and as you pull on the cable more the faster it opens. It helps with light throttle application, the throttle wont be as on/off. This problem would be amplified with the stock linkage. Youd have to figure it out, but as an example you might have the equivalent of the original full throttle when the 60mm is opened only 3/4 of the way. Which means youve really only given yourself a shorter push on the throttle for the same power, which doesnt seem beneficial. Quote Link to comment Share on other sites More sharing options...
