turbo upgrade on 6.7
 

i have a 07.5 dodge qcsb 6 speed manual. i wouldnt mind going with a bigger turbo but still small enough to keep from a lot of spool lag. but i dont want to loose my exhaust brake is there any way of keeping my exhaust brake with a aftermarket turbo?

im running a silver 66 i lost my e brake but it runs awsome u could always add a pac brake if u really want one but there are a couple companys that have the modded turbo for the 6.7i thinks its better to get away from that vgt turbo my opinion

industrial makes a bigger vgt turbo. i have sold a few. they work good but if you are going to run high boost they still will run high drive pressure. i like my vgt with the exhaust brake but i keep the boost down. i got to have the exhaust brake towing. it depends on how you use the truck.

with you having a manual i wouldnt go any smaller than a 66/74/14 however the only way of keeping the e-brake is buying an aftermarket brake. My suggestion forget it ever had a e-brake put a 66 on it and have lots of fun. you can also spool that turbo on a stock fuel system with very little if any lag

Will i have to change my manifold or will i be fine with my stock manifold

I'd recommend a Industrial Injection Thunder 330 Turbo.

im runnin a 62/80/14 and love it

04.5-07 manifold and everything is pretty much bolt and go
