I purchased a GMC Sierra T3T4 Turbo Charger Kit and i want to install it myself.I need detailed instructions on the install procedure as well as tunning

No turbo before,It is a 2007 6.2 L, LS9 , 403 hp No turbo before,It is a 2007 6.2 L, LS9 , 403 hp

Ok,



The first thing that you should really do is look at the compression ratio: which on this model engine is in the range of 9 - 10:1 ratio, which is to high for a turbo of the size you have.



If you mount a turbo of this size and run it at say 5 - 7 lb boost your engine may last 50 - 100 hours.

Any higher and your going to blow the bottom end out, unless you have fitted a stronger bottom end.



If not you will need to buy steel/cooper head gaskets, this is so that you can drop the comp: ratio. Down to at least 7 - 8:1.



Apart from the above it is quite straight forward, proveided you have all the parts needed to bolt it up.

Procedure:



1. Fit exhaust manifolds that are matched to the vehicle and the turbo flange, if not then you will need to frabricate some flanges on the current exhaust manifolds.

2. Fit the turbo/s, with gaskets etc.

3. Ensure that the exhaust housings are facing the rear of the engine or in a position which will allow the best exhaust flow.

4. You will then need to find a oil gallery and water outlet/gallary which you can tap into, now your oil/water hose's you have with your kit, should have all the fittings for the oil hose to engine block oil gallary, this should be the same with the water line.

5. After fitting these and routing them, your almost there.

6. If your running a front mount intercooler you will need to try and make all the inlet tracts and intake tracts as short as possible, to the intercooler and the engine intake manifold/throttle bodies.

7. Once you have done all this all you need is to hook the hose coming off the wastegate actuator to a vacum connection on the intake manifold, if your turbo don't have and internal waste gate attached then you will need to ge a external waste gate or your going to blow your engine in the first 3000 - 5000 rpm you pull in it.



This should help you some of the way, as for tuning you need to wait until you have it mounted and weather you have gone external/or internal waste gate method.



Let me know what you intend on doing and I can give you more indepth information.



Thanks

Here is the kit I bought GMC Sierra T3T4 Turbo Charger Kit will I need more to complete the install ? where do u recommend i but head gaskets from ?How would a guy modify the stock exh manifold is it not cast iron.Do you think the turbo i bought is to big ? Should i purchase a different one ? Do they have to change the head gaskets on all the kits? From what i have read the magnison charger does not need head gaskets or the STS turbo,what is the difference Jason
