Thanks Al I figured I was going to have to make something. I thought about drilling the shifter knob out where it would slide all the way to the floor and then put an old school knob on it. Then I could still use the bottom 2 gears if need be plus wouldn't be accidentally bumping it in to lowside !

Does anybody make an aftermarket air shifter for these trans?

Looking for a complete engine brake for a 1990 em7 mechanical engine

Ok guys I've got an rd690s with Dayton style hubs and wheels and I'm thinking of converting to budd style has anybody done this? Just wondering how to figure out which ones fit when I go to salvage yard.

Called them today 84, great people to talk with going to send them my old set and he said he had some 100hp bigger on the shelf he would send back to me thanks a bunch for all your help!

I can tell a big difference in the way it pulls but it just doesn't seam quit as snappy as it did before, I've got all the adj. I can out of the pump low and wide open side and my egr is still really good so I think I have more room to play. I'm thinking that if I go bigger on my injectors and it heats a little I can always back the pun off a little , I'm wondering what a stock set of 400 injectors would be like

84superdog the turbo is part of the prob. I blew my old on so when I got the new one I ordered one for an e7 350 so and they are rated for 350 to 400 hp. I do have the pump opened up and it does run good but I'm thinking I'm running short on fuel now. Thank for the info

Ok guys I've got a 1990 e7 300 all mechanical,I'm looking for someone that has bigger injectors or can take an old set that I have and work them over.ive already turned the pump up and have went to a bigger turbo which made the truck pull better and dropped the egts a lot but the throttle reponse is a bit slow

hey guys ive got a 90 r model and im looking for a tach or even the ratio of these tachs so i can order an aftermarket one, anybody got any ideas?

Although that does seem a little high to me I do believe strongly in using OEM parts when practical. In the aftermarket, ebay seems to have vendors that supply inframe kits on a regular basis. Although nothing fits what I would need exactly, the prices do seem reasonable. Most of these that I've investigated are "FP Diesel" brand which is the aftermarket wing of Federal Mogul.

I've heard pros, and cons to using these parts but I'm no professional mechanic and an E7 series engine is beyond my realm of knowlege.
