Default 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?

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

I'd recommend a Industrial Injection Thunder 330 Turbo.
