Exhaust and tire size for my BJ42

[crushers]

i have seen a total of 2 and both were very poorly designed. for $3000 USD i would expect to do NO mods and have the bugger bolt right up...

In the AXT instalation instruction ( that I can see through a web cam ) appears all easy and bolt on .. there are interesting thing, if all setup is more complicated then that.

Should a turbo'ed 3B @ 0,8bar, intercooled with stock 4speed gearbox and 4.56 R&P would be enough for pushing 35's, or should i go with higher R&P ratio? for now i have the stock 4.11 with the 35's but it seems it's not a good option.

I am running 4.88 gear with my BJ42 with AXT turbo and 3B with 35" boots. I have found that it to be too low geared for wheeling the torque does not line up with the H55F tranny. I am going to go back to 4.11 gears worked better. However if you have the H42 I would think the 4.56's would be ideal.

cheers,

Michael

I have yet to see or do a AXT turbo kit that does not require a few mods. both on 40's and 70's (all 3B engines).

cheers,

your setup 35" + 4.88 + 3B + Turbo = 37" or 38" easy .. with 4.56 and 35" you have the best powerfull setup .. and with 4.11 best milleage.

There isn't a difference in the frames in the 83-84 BJ42s with the H55F? I thought the curly-tube cross member on the frame was moved back slightly to accomodate the longer 5 speed tranny?

Can anyone confirm? Looks so tight if the transfer case would be 8 cm further back.

I believe the H55F moves the transfer case 88mm further back. Some folk lower the gearbox cross-member so that the rear prop-shaft flange clears the tube cross-member on a standard BJ40 chassis.
