So after buying my V I joined the forum and have been reading hours a day, everyday..... The car is an 04 43k, Maggie, borla, diff is a 3rd gen.

Well the car threw a P0420 code so the cats are shot, the clutch is giving me fits (slipping on quick shifts), dual mass rattles, crank pulley wobbles a bit. Here is my plan so attack. I am on a bit of a budget

Headers no cats: OBX I understand the fitment issues are possible

Crank pulley: I have a call in to Jegs about their 10% OD pulley or will be going with the IW

The clutch has me thinking a bit more i know lots of people use the LS7 unit but IDK if I'm sold on it for these heavy cars paired with a blower..... Mcleod twin disc? Other clutch options? Want something that drives nice holds and won't break the bank.

Motor mounts and trans mount: RS CS or UUC?

Shifter: pissin


Input good or bad pease.

I only have experience with the LS9R setup with near stock power levels, but really like it. Like stock driveability with faster revs and less weight.

I'm certainly not apposed to an LS9R deal other then the price........

It appears as though the price I saw was much higher then I have found..... 1100 for the LS9X ain't to bad.....

I don't think that the LS7 clutch would be a good match for your current/future mods. I don't have any personal experience with it but I would assume that a maggie/headers LS6 is getting close to the HP limit that most people would suggest running the LS7 clutch with.

My thoughts too that's why it is not a clutch i want...... I see you're in wisconsin too what part?

If you are on a budget, don't do headers-- they are not critical for FI cars. Go with revshift mounts and LS7 clutch. Any damper but stock and pin it.

I'm running an LS7 clutch with the mp112 and 2.6 drive pulley 465rwhp/460rwtq and i have absolutely no slipping issues, car drives great.

I'm thinking about holding off on headers...... not because of money, my budget is $3000, but because I don't want to hassle with wrapping and melting wires etc etc etc. I think it will be clutch, 10% OD lower pulley, 2.6 upper, and a tune. Thoughts?

So clutch is the biggest question...... spend the extra coin on a twin disc or try the ls7 unit?

LOVE my twin disk! LS9 kit is pricey, no doubt ... not sure of the cost of the Mcleod.

And, as much as I love HAMSTAR, headers really do allow an LS6 to exhale especially with an OD crank pulley. Get some steel ones to save some significant bucks. They'll easily last five or more years, I'd suppose.

Also fuel pump? I'm still on a magna-volt..... Direct bolt in unit?

Well here is what I'm thinking about headers..... In N/A form headers make more power by increasing volumetric efficiency, the blower takes care of volumetric efficiency. The power increase on an N/A motor, about 20-30 running catless, would be greater then that of a blown car...... If we take the 30 possible increase and say 1/2 of that is from cats, 1/2 from headers, I'm taking out the cats so my possible gains are down to 15 and the fact that the blower is forcing the air intakes that gain and shrinks it down even more.......

Regarding the damper, what do you mean by any damper? From my knowledge about aftermarket FI you want a quality damper. It's a good safety feature for your engine. ATI is a popular choice and they sell pinning kits. I believe their dampers are rebuildable.

I will pass on any more specific advice on damper. There is optimal, then there is what's good enough based on what you can afford. FI guys like DMM are the ones to ask about this.

I'm going with the Jegs 8rib 10%OD SFI approved lower and I will pin it.

A lot of people with maggies go one step colder than stock. I stuck with the stock style plugs, they work fine.
