i got home for the day and thought the turbo swap would be simple and quick, WRONG. i finallly got the stocker off after some heating and beating and thought i was in the clear because i got a thunder 330 "direct replacement" turbo. Once again proved wrong, the wastegate on the turbo hits the motor mount and wont let it go on the flange. Tried taking the wastgate off to make room and got the the studs started. Then another problem the studs they sent me to replace the studs that came out in the turbo are too short to screw on both sides. This is driving me up the wall so anybody with any help would be more than appreaciated because now i have to leave (drive a semi) and wont be back for a month and truck is tore apart in the driveway.

Been doin some research and can't find any documented turbo swaps, but have found that grinding a little bit of my motor mount ( not much at all is needed) i can get the wastegate to clear which is good. Still is the mounting flange for the turbo, there is two studs in the turbo and two in the manifold. the new studs they sent me are too short and do not know what anybody else is doing. Could i just use whatever bolts i can make fit as long as its bolted in tight? Turbo is a thunder 330 and manifold is stock.

 

yes you can just use bolts, i would try to find some stainless ones tho

btw if you would have taken your manifold off with the stock turbo still attached then installed the new turbo onto the stock manifold then drop the new turbo/ old manifold back down in there and bolt the manifold back up you wouldnt have had to grind on the engine mount

 

Thanks for the info i will definiatly look for some stainless bolts. Also im on the road right now so i havent grinded the mount just yet, so ill try taking the manifold off when i get home cuz that sounds alot better to me than grinding.

 

yeah belive me your not the first to try it like that and it not work out for them

 

(sorry i dont know much on this but just thinking) is it possible that you can clock the turbo to keep from hitting the waste gate?

 

I dont think so but i got an email from industrail injection saying that i need to pull the studs out of the stock manifold and put the short ones in to avoid grinding the motor mount then reuse them in the holes that are left. It will fit after i swap the studs out, i just need to get home and off the road.

 

Got home today and got the turbo installed. Luckily the studs came out very easy only (80k) and the short ones screwed up into the manifold easy. I used lots of anti-seze on every fastner. With the new studs in i didn't have to remove the manifold or grind the motor mount. The hardest part was hooking up the oil drain(behind wastgate under truck against motor). I then plugged in the old sensor out of the old turbo in and zip tied it out of the way and got no codes when running it. I took it through town and on the highway and all i can say is wow. I almost can't shift fast enough to keep up when it lights. Not much turbo lag (like a stock truck with no programmer or mods) but you have to roll into the throttle instead of stabbing it and it lights alot quicker. I would have to recommend it to any body lookin for a bit bigger turbo and maybe doesn't want to many mods. All in all I am very happy with my choice with the Thunder 330.

 

Ya they are great turbos.
