Your obviously buying & installing every performance mod available for the 6A12 motor, which is great, I'd love to have the coin for that, but just be wary, for every performance modification upside, there is a down side.
While putting in a light flywheels will increase the cars ability to accelerate, the flip side is that you are going to loose your torque momentum up hills.... you're going to be constantly changing down gears when the car is under load at low rpm.
The limo diff will obviously increase your traction, but are you aware of how noisy they are? They also 'pop' and crunch & f*ck around when you are doing low speed maneuvering like parking. It becomes a nightmare for daily driving (I've got one in my other car)
Im not trying to discourage you, just giving you a heads up

This is the stuff thats not written on the packets of these type of parts... I went absolutely postal on another engine I built for my other car, it was just painful to drive on the street - I'd crossed the line... so I pulled the carpet out, slapped some slicks on it & turned it into a race car

Mmmm... Problem is quite often you dont realise these downsides untill they're already installed...
Ben, Quick question regarding this, Is my 8:1 CR pistons going to drop the low end performance of my engine? If so, combined with my lightweight billet flywheel, im going to loose a lot of low down...
Just trying to get an idea of downsides i should expect in the new engine.
Tintin, great to see some major work going on in that thing.. Is it a mirage (hatch)?? It should be insane. good job on all the work. we want dyno's and qtr mile times when your done!

you can quiet lsds down by putting the right type of oil in em apparently... more the organic type than synthetic, or something. i dunno i dont change the oil in mine. its only a pain when you need to do 1st gear turns for me... 2nd gear going around a corner it just groans, but 1st gear it'll groan and spin the inside wheel and click and fart etc but thats cos i have the cusco MZ model.. the RS is supposed to be slightly different slightly more expensive and offer slightly more lenience when turning tight corners...
so much grip though... wet or dry

Big difference is that you have big boost to overcome that... a well tuned turbo setup will compensate.

i dont have that many people in the car so that should be ok but when you mean lose torque will i lose it in normal driving cos i want to get as much touque as i can

You'll lose low down torque, but gain higher up. Problem is higher up torque is not usually accessed during normal city driving.

would it be best for me to go for the rs lsd then?

yeah its slightly better for around the streets..(they tell ya) i dont know how it is first hand. i think the evo3 lsd that you can put in ftos is the same. the MZ is just advertised as the 'drag' model and its slightly cheaper but it does the same job, just it's more aggressive.
