so i sure in the hell hope so  ;D it had better make better lap time in the trails  rofl   it def needs more bottom end and the only way to do that and keep all the mid range is a 1st gear so i will drop 2nd 3rd as well.....i think .25 rotation and raise 4th to a 120 from a 130. now once they get it apart and can tell me what the actual gears are in there i'll know more. i still have a gut feeling that my current 1st/ 2nd are a touch higher than i think and my 3rd is way lower than it needs to be. 3rd is so close to 2nd ( remember i have a 3 speed so your 3rd and 4th) that i blow though to rev limit right now! rev limit is 6200 rpm right now and since this is current head on enemy's engine i am swapping onto mine, i know it will easily run to 7500 rpm as he runs it to 8k.  another 1300 rpm capability is always nice when needed at say st a pulling a long dune  :D    i am going to make one mod to this chassis for ease or re install. i need to quit making things so tight fittting lol the really interesting part will be to see what kind of difference another 70 cfm with a higher lift cam makes especially in mid range!

another big plus will be an exh manifold that doesn't leak on 3 cyl's  LMAO turbo should be a little more responsive  :m :m 

that part is really my fault, i knew it was warped but thought i could make is seal up for the season and was wrong. i know what he did when he was welding it and how he warped it. i'll put it on my dads horizontal mill and true it up.

i didn't take a pic but when i drained the lube out of the trans i saw some material on the magnetic plug. not a horrible amount but a little more than i though should be there. i used roal purple gear lube and have not changed the oil since i installed the trans. yes i know that is a no no and i know better but it happened so 3 years of run time, it came out as black as a chalk board. didn't smell burnt but did have a silver color floating in it in the bucket.  i assumed the silver color was prob aluminum from the case or other aluminum parts?? it will get new gears anyway and i have a brand new r&p for it if needed as well as a used case sitting here.

also where some of my oil leak was the front and rear main seal , a tiny bit, the vast majority was the trans. it was coming out the shifter bushing on the pbs shifter assembly. come to find out pbs doesn't make the mid engine shifter anymore so i may have to send that to someone and see if they can machine a new bushing for it. i did over fill the trans but damn after 3 years it should've leveled it self off.

I doubt if they interchange,  but I have a mid engine  PBS shifter on a VW type1 trans, if that would  help you.
