Can u Frankenstein a TB?
#38
Okay, so final round of questions so I can make a final decision before investing any more $$ into the project:
--What is the diameter of the 501 MAF? (tbd, got one coming in the mail)
--What's the maximum bore diameter that the stock 4g94 IM will support? (was told 60mm, give or take...prob more on a 4g93)
If I can get these numbers, I'm going to make a final decision between the stock evo TB, or aftermarket 70mm or 80mm TB. I'm going to cut and weld the stock cruise assembly onto the new TB, after taking it apart it doesn't seem to be too too complicated (but welding aluminum is ALWAYS fun:-p). Do I need to keep the sensor on the cooling plate, or can I disconnect this without any issues?---you can, but there's no point to it...didn't notice any difference as-is, prob see a slight diff with a phenolic TB spacer
Thanks guys

okay, I bought a 2003 evo TB, definitely a lot more airflow on it from the looks. I'm going to be welding on the cruise control assembly, and have some questions about how to disassemble the stock evo TB throttle linkage, as it seems to be press-fit whereas the 4g94 is bolted.
Here are some pics. If anyone can give me some pointers so I don't break anything, that would be great... even a blown-apart diagram would be great. Thanks for the help. I'll post updates with how it goes.
This first set is of the stock 4g94 tb:
The nut and bolt system seems pretty straight-forward on the 4g94 tb, but here are pics of the evo tb:
(evo on the bottom)
This is the retension part of the throttle, and I'm wondering how to disassemble this...
I'm assuming once I get the one off of the evo tb, i can replace it with the nut and bolt system from the 4g94 and then weld on the cruise assembly to make it all work. There is room on the evo TB to mount it with some careful aluminum welding...

ran into some delays, ended up having to rewire my amp/alternator setup, got my new rims and tires on, and installed a 501MAF. so this thursday/friday is the goal for the mockup of the evo TB with cruise...once i get everything assembled i'll decide how i'm going to weld everything, and track down any extra aluminum i have lying around to make the job work...
