I have a Holset HX55 turbo I will be puting on my LS1 soon and its pretty tight for space as far as pluming and everything else in the engine bay. It would be much easier to do a rear/mid mount. The car is a 1978 corvette so I dont have the space like some do in the engine bay.
I do have a spot before the rear end so it wouldndt be completly in the rear of the car, pretty much right behind the seats under the floor. I have heard its no good putting large turbos in the rear.

Does anyone have any input on how bad this turbo will lag if I put it not front mounted?

Thanks

Do you know the size of a/r of the exhaust housing ? I'm going to assume you don't since its almost impossible to find out with holset turbos
I have a hx55 in front and spool time is ok but I would not recommend having it in the rear

Yea I have no idea on the a/r. Thats what I was thinking probably too big. I have heard good things about them being ran up front. How do you like yours? What hp are you getting out of your car and what have you upgraded on the motor?

It is a very large and very heavy turbo. I wouldn't run one in a rear mount.

TC series turbos are nicely sized for rear mount applications. They are relatively small frames for their power potential.

The a/r is stamped on the housing in cm's. Im going to run a ht60. Probably rear mount for now

HT60 in the rear has got to be larger than mine. I would love to know how that does when you get it installed.
