Kazuya1274 Posted November 2, 2004 Share Posted November 2, 2004 Searched around for this but couldn't find any info. I recently installed a 60MM 240SX TB. It is using the stock linkage and a spacer. The pressure required to push down the accelerator is quite lower compared to the old 50MM stocker. I noticed while looking at the stock one that it has a return spring on it that is mounted with a bracket on the TB. This is what gives the stock unit its pedal pressure. I am looking for some options to increase the pedal pressure on my new throttle body. Or, should I just get used to the lighter pressure? Its been raining lately, and the car is awaiting its new exhaust, so I have only driven it a few times since getting it back together, so I was not used to the lower spring pressure. Any ideas or pictures of other 60MM TB setups? Quote Link to comment Share on other sites More sharing options...
fl327 Posted November 2, 2004 Share Posted November 2, 2004 I switched the spring to a 280z spring, and everything felt like stock. Quote Link to comment Share on other sites More sharing options...
z_boi Posted November 2, 2004 Share Posted November 2, 2004 u used the extra spring from the stock tb with the bracket. but i had to buy a longer bolt to make it fit. u can always add springs to make it as stiff as u want it to be. Quote Link to comment Share on other sites More sharing options...
Kazuya1274 Posted November 2, 2004 Author Share Posted November 2, 2004 z boi, I cannot see where to mount the extra spring from the stock TB. If you could e-mail me a picture of your setup, I would greatly appreciate it. I took the car out today, and noticed that the pedal travel is Sticky at the onset. This is why I have a little trouble moving from a stoplight smoothly. I end up giving it a little more gas than is needed. I did not get a threaded link that connects the car's throttle linkage to the TB. I am not sure where to get the parts to make one of those, so if anybody has one, I would gladly pay you for it if you can send one to me. I think I need one of these because the car's throttle linkage is almost all the way up, and the angle may be causing the throttle to stick a little bit at the top of the travel.

Kennysgreen280zt Posted November 3, 2004 Share Posted November 3, 2004 I usually use the stock "inner" spring of the 240sx TB when swapping the Z linkage on. You can pull the spring almost to the tension you want by the number of times you wrap it around the shaft. If that makes any sence to you, try it. I might post some pics later if I have time.
