Ole Windy Posted July 20, 2021 Share Posted July 20, 2021 Wouldn't mind upgrading the turbo on my 1988 Superliner. E6 350 reman by Mack stamped 10/94. Any help is greatly appreciated.

AZB755V8 Posted July 20, 2021 Share Posted July 20, 2021 I would recommend a Borg Warner Airwerks Turbo. A SX300 or maybe a small SX400 would defiantly add a kick in the rear to the old dog. I do not mess with E6's but it is simply matching what you got with 25 year newer technology. You need to measure the intake diameter and exhaust diameter of the turbo. The other thing is the A/R number on the exhaust turbine housing. If these three things are known a turbo can be selected that will run circles around the stock one. Adding a turbo blanket helps also. Boost should be in the range of 50psi plus. Maybe turn the fuel up 10% and it will run like never before. 1 1 Quote Link to comment https://www.bigmacktrucks.com/topic/67430-e6-350-turbo-upgrade/#findComment-477141 Share on other sites More sharing options...
John3406 Posted July 20, 2021 Share Posted July 20, 2021 Holset hx50 from antrim. Mine makes 40 lbs boost with a ground fuel plate. It will run with 3406 cats 1 1 Quote Link to comment https://www.bigmacktrucks.com/topic/67430-e6-350-turbo-upgrade/#findComment-477146 Share on other sites More sharing options...

You want to be careful trying to pull too much from an E6 it can break the block at number 5 main bearing! there in lies why they went to the E7 block with buttress screws! A candle that burns twice as bright lasts half as long! Just sayin! 3 2 Quote Link to comment https://www.bigmacktrucks.com/topic/67430-e6-350-turbo-upgrade/#findComment-478636 Share on other sites More sharing options...

A candle that burns twice as bright lasts half as long! Just sayin! Agreed with that and second it too. There is always trade offs with modifying anything Durability and reliability go down as horsepower and performance go up. Everyday truck I would not mess with but a hobby or occasional run truck why not? Can't do to much anymore with emissions and all anyway. Heaven forbid some black smoke comes out of the stacks on a old truck these days. Just get a bigger factory engineered engine and all is solved, just sayin... 1 Quote Link to comment https://www.bigmacktrucks.com/topic/67430-e6-350-turbo-upgrade/#findComment-478718 Share on other sites More sharing options...

If you have a bosch p pump you gotta slide the fuel plate forward to gove it more fuel. Im my case i ground it so it would go farther. It runs strong. I pull 96000 pound loads daily and as long as you keep the boost up the egts never go over 900 deg.

Ole Windy Posted October 30, 2021 Author Share Posted October 30, 2021 Sorry my Mackites! I've been terrible busy. I haven't had much luck finding a SX300 with the correct exhaust port measurements. I have a reman E6350 1994 birthday, manifold is 2.75 x 4.50. That's center to center on the studs. Coming up with blanks. Anyone with a part number would be awesome. Thanks!
