I am contemplating replacing the GM-4 turbo on my 1994 6.5 diesel engine. Will it effect the engines performance? Will I increase the egt's very much? help kelpie100

I replaced the GM-3 with a GM-8 on my '93 last year, the -8 seems to build boost a little quicker. Aside from that, i can't tell a lot of difference.
