Hello All!
Recently bought a 2008 Hummer H3 Alpha 5.3 that I am right now reaconditioning and build!
I want to put all the bolt on that is possible on this truck, that is: Airdoc Intake, Shorty headers, Afe pro dry S filter, Aero turbine exhaust (removing the resonator and installing it in that part), muffler delete, efan conversion (with 2 pullers and 1 pusher), Jet Ported Throttle body and of course a PCM tune from PCMof Nc...so my main question is regarding headers:
There isnt almost any option about shorty headers that is a direct install and fit for Hummer H3 alpha (disgusting, because in the i5 (less popular and common engine than 5.3) there are some options over there.
The problem with the 5.3 v8 headers in the h3 is that in driver side area, the exhaust manifold have a specific part number not being share with other 5.3 platform (except 5.3 v8 colorados)....so the problem is the fitment between engine and steering shaft column...
I recently see that best option is the BBK Headers with part number #40050 (ceramic coated)...hoonigan website tell that is a fit for a Hummer H3 but emailing bbk, they say that #40050 (or 4005) are not being tested in a Hummer H3 alpha, so they cannot guarantee direct fitment..
So my question is:
Has anyone installed a BBK Headers on his/her H3 alpha? If not, there is another shorty option out there for the Alphas?
Hope anyone can help me out....after all of these mods I will continue with offroad mods (Front and rear locker oem install, Fox shocks, Outfitter design kits, Tranny cooler, refurbishing every bushing, wheel bearing, etc...)
(Thinking about doing a Thread Build)
Thanks!
