Ok let's get a list going, then maybe someone working at a dealer can work out a price for the actual throttle body:
1. quadracer0387
2.
3.
if we get the 20 people and since you're the first one on the list $300 total (intake will be polished SS, $50 more if you want it powder coated)

"We took a throttle body off a chevy Colorado 4.2L and using an adapter plate attached it to the stock supercharger. This new TB is 3.5" giving the ability for more air flow.
Results showed 1.5psi increase in boost and 2 lb/hr increase flow through the MAF sensor. We will have dyno results soon. From the butt dyno we can definitely see an increase in the lower end, more of a kick when you stomp on it.
Also we had the throttle hooked up to our full 3" intake all stainless steel and powder coated (this is a good item for anyone who has seen wear marks in their aluminum intake)"

ok so the injen is 2.5 from what i understand is a little to small for the bigger TB so my understanding on this is i would have to buy the REBEL 3'' custom intake for $300(wow thats steep), the spacer for $50 not bad considering they origionally wanted $100 but its still just a spacer for $50, and then i would have to buy the actual bigger TB for around $150 new or prob $40-50 from a junk yard and then pay for a tune...
thats like $500 (with a new TB)...then going to have to pay to have it tuned cost from 100 to 250?
so over all with new TB, spacer, intake, and tune were looking at prices from $600-750 if im even going to think about doing this i want to see so solid dyno numbers i mean i can spend $50-55 for a smaller pulley and get 1.5lb boost out of it...
i think i speek for everyone when i say we are going to need some solid dyno numbers to consider this...(if anyone thinks im way wrong just tell me and i will listen to what they have to say i appreciate any information i can get) and im sorry if it seems like im flaming on anyone i dont mean to im sorry and i know you guys at rebel are good guys and have good products...but anyway i want to say thanks to REBELAUTOWORX for putting us another product out there its great to have options

thats 100% what im saying you are wasting all that money for so little of gains its not worth it you can do so many more things with that much than this and only get 5-10HP tops...its not my decision though everything does things diffrently for the people who go for it good luck and hope it works out good but im not going for this one that much of a gain isnt worth the money to me...like acidangel said if the TB and the spacer came together for 200-250 tops and the intake was only around 150-200 as a package deal i would be all over this...just consider this before you guys buy...
"Remember this spacer also provides more area for air to be stored for quicker response."
From everything Ive read TB spacers will not give any extra horse power. Ive seen this discussed many times before. This link below actually shows a tb spacer causes a loss in horsepower. Dont know if forced induction is different, maybe someone can elaborate.
So basically thelarger tb will help hp but the spacer is just a piece to attach the larger tb not an actual piece that increases hp.

It is simply a spacer made to be an adapter plate.
By all means, try to install the 4.2L TB on your charger, let us know how things go when the butterfly opens only 25% and hits the mouth of your charger. And you go in to limp mode.
The spacer was made specifically to accommodate the larger butterfly in the 4.2L TB so it wouldn't hit the charger.
Yes it looks like the one in that pic, but was machined different to act as an extension of the larger TB rather than a spacer.
You can attempt to buy the ebay spacers, which are the like the ones mentioned on that webpage, go ahead, the webpage is 100% correct, throttle body spacers WITH GROVES TO SPIN THE AIR are as useless as **** on a bull. But that's not what we made here.
The extra power and HP we feel DOES NOT come from the TB spacer. It comes from the fact that you are putting on a TB that is a half inch larger, thus allowing WAY more air, a huge amount more, in to your charger and engine. And the fact that we have the spacer/adapter on there give the M62 more room to bank the air, so when you stomp on it, and make boost, there is extra air there with no delay. Resulting in a noticable amount of "pep".
Nice response and great info there. But...Will this mod actually increase the boost?? That is not something that we really need, considering that the M62 is peaking efficiency range at 20psi and we are hitting that with a 2.7 pulley on a chilly evening. Just looking to do all my research before purchasing ya know
Or those who are running larger pullies then a 2.7. With a 2.9 and cooling mods along with a bigger TB your looking at more boost without decreasing the pulley size. To me this means less heat and more boost and more air flow on a larger size pulley. = safer from what I understand.
