Reply #18 – December 16, 2010, 11:08:25 PM Quote from: turbo_88_XR7;345988 i suggest an SC bottom end lolalready part of the plan:headbang: .....still debating over whether or not to go with the forged 4.2 stroker crank though..... think I just wanna leave it stock 3.8...Idk if its worth it when the boost is added... more base horsepower but more displacement means less overall boost ....so would probably be the same.Doesn't matter its $5000 into my future so I've got LOTS of time to plan:rolleyes: Quote Selected
Supercharged 3.8l V6 swap! Reply #19 – December 16, 2010, 11:36:32 PM LOL less boost and same relative power? wrong train of thought.. if that was correct, my 408 would be stock bore/stroke and still be hitting 9's.. the increased bore/stroke of a stroker will definitely boost the power even higher with boost applied Quote Selected
Supercharged 3.8l V6 swap! Reply #20 – December 17, 2010, 08:36:53 AM I wish I knew more about the 3.8/ 4.2 engines. I have 0 experience in them and even less knowledge.In general I'd start by setting a HP goal for the engine you choose. That would be set by the known limitations of the hard parts, crank, block, transmission, etc. Once you have that then you can start to choose the turbo/ sc, injectors/carb, and all the other stuff you need to support that HP goal. I personally like to use as much OEM stuff as I can. The parts are cheaper, more plentiful, and generally pretty robust. It sounds like your plan of starting with a SC engine is a good one.

Supercharged 3.8l V6 swap! Reply #21 – December 17, 2010, 11:45:03 AM i've seen SC'shiznit 14psi with stock internals, but that's with a charger.. i would hang the boost around 12psi, you should be pretty satisfied with that as long as your tune is right Quote Selected
Supercharged 3.8l V6 swap! Reply #22 – December 17, 2010, 12:19:19 PM I have heard if going for these motors the 94-95 M90 Eatons are the ones to get. Quote Selected
Supercharged 3.8l V6 swap! Reply #23 – December 17, 2010, 12:21:02 PM definitely, they're monsters.. the shaft bearings are also a lot stronger than the older chargers Quote Selected

If your planning on going with a total SC conversion that is the preferred year donor car to look for. Better supercharger and the motor was a little better built too, to handle the extra boost. I forget exactly what was done to it though, not much. Quote Selected
Supercharged 3.8l V6 swap! Reply #25 – December 18, 2010, 09:39:00 AM Internals were forged and block was stronger IIRC. I have been told they can handle 300 hp on the stock pulley. Step it down to a 5 or 10% and the sky is the limit. Quote Selected
Supercharged 3.8l V6 swap! Reply #26 – December 18, 2010, 09:02:35 PM If youre talking about the sc engine,..... they were all forged..... Quote Selected
Supercharged 3.8l V6 swap! Reply #27 – December 18, 2010, 10:11:43 PM As I said it was all in the superchargers they were more efficient. I am fully aware they were all forged. Quote Selected

Supercharged 3.8l V6 swap! Reply #29 – December 22, 2010, 12:19:41 AM i believe the 94-95 pistons domes were a bit different, as well as a little factory modification to the heads to support the M90's air flow.. the best thing i ever did to my SC was bolt on a pair of OEM non-SC 3.8 headers with an SCP 10% pulley.. it really brought it alive with the chip, fresh air intake, bigger MAF and underdrive pullies Quote Selected
