Want to swap to 98-99 TB
Want to swap to 98-99 TB I want the smaller cam 98-99' TB on my car because I love the way the throttle feels compared to my 02' TB. I have heard there is a difference in cable lengths, anyone know what I have to do to get it to work?
Thanks.
Thanks.
Yeah I know there is a difference in the cam size, that is why I want the older throttle body. I just need to know how to get it to work on my 02 ls1. I have read that the cables are different length between the years so I dont think I can just bolt up the 98-99 TB, or can I?
Well by using a piece of wire I tried to measure the cable from my moms 99 TA and my 02 WS6. I know this is fairly innacurate but if they are not the same length, they are real damn close. So hopefully I can bolt it right up.
I am really surprised that no one has asked about this before or had some experience because the 98-99 TB makes the car feel so much more responsive. The smaller cam in the older TB opens the blade faster than the new ones. My 02' with supposedly the torquier camshaft is of no comparison to the response of my moms 99' TA. We have the same mods by the way.
Before I start pulling apart my moms intake if anybody has some info it would be greatly appreciated.

You and your mom drive T/A's...that's pretty cool 
I would say go ahead and throw her's on your's and see if it works. It's pretty freakin' easy to swap TB's, you can pull it off in like 3 minutes. If your cable is significantly longer than her's then the worst I can see happening is that you will push on the throttle but the blade won't begin to open until all the slack is pulled out of the cable. I say hike up your skirt and give it a shot

I say hike up your skirt and give it a shot I believe the length difference in the cable is 3/4". You can put the 98-99 tb on the 00-02 car, you might have to shorten the length of the cable in order to get the throttle body to open all the way. You can place a couple zip ties on the cable that goes through the pedal assembly to shorten it.
I would be careful if you are putting the 00-02 on the 98-99 because with the larger cam and the shorter cable the tb might not close all the way, in this case it would not work. Tim

Well I am switching from an 02' TB to a 98-99' TB so I wont have the problem of it staying open. I put my moms on there and the cable had too much slack in it. When I took it back off, I realized that the cable has adjustment (reminds me of an inline fuse holder). It might be enough adjusment to fix the problem of not opening all the way. To adjust it you pop off the black plastic clip that holds the cable, pull or push cable to desired length, then pop the black plastic retainer back on.
I didnt feel like putting the 98' one back on again to try out today but I adjusted the cable on my car to make it tighter. It worked just as I thought (took up slack in cable and would not let 02' TB close all the way) but I will have to put the 98' one back on tomorrow to be sure there is enough adjustment for the blade to open all of the way.
This will be awesome when I get it to work, I dont know why most people have not noticed this difference in response!

glad to see its working.
probably because the majority of people dont drive near stock 98-99 and 00-02 cars to notice the difference. or they upgrade to a better TB

If you really want a '98-'99 style cam for your TB I'll trade you for your '00-'02 style. It's really easy to pull it apart. You just take off the TPS sensor and then unbolt the TB blade (need a torx bit aka star pattern bit). Hold the throttle full open and then pull the blade out. Next you just tap on the end of the shaft (where the TPS was) and pull the cam/shaft straight out. Let me know. I won't charge anything being that it's a direct trade.
Thanks for the offer, i will let you know if I want to trade but I might just take my moms and swap cables if needed. Just curious why would you want the 01-02 TB? My car feels sluggish after driving hers.
I have a couple spare TB's sitting around (I port them every now and then just for a hobby on the side and sell them on ebay). Yeah as long as you swap the cables b/w the 2 cars then you'll be set with swapping the TB's.
We need to know what each car has as far as TCS and cruise control. There are cams inside them as well and would need to be swapped in order for the range and speed of the openning to be matched to the TB cam.
I have a 99 and personally feel the cam opens too fast. I was wanting to swap to a later model so I would have more control with down shift throttle blips. The 99 TB cam is just too sensitive to match up the RPMs every time. Plus the 99 cam doesn't have much effect between 50% and 100% throttle. The majority of the control is in the first 30% of opening.
Really, the best way to change the characteristics of your throttle would be to reshape the cam. If you had a spare one you could reshape it so it has the same overall opening distance, but with the quicker opening near the closed position, like the 99 cams. That's what I would do.
