[old man rant]
I have an SIDI, and I can appreciate people wanting to bolt on some force feeding... but for the cost, the headaches, and reliability issues you'll face later on, it's just not worth it folks.
In my younger days, I went completely nuts on a previous car. At first it was just going to be a small turbo conversion.... low boost, stock internals, nice and 'easy'.
Then you do just a tad more... why not, because you've already spent thousands.... what's a few more right?
Then reliability of the rest of the drivetrain starts to become an issue. Clutch, drive shafts, new dogbox sans syncros- straight cut gears will be stronger, no more daily driving though.
Now the ignition system is the weakest link.... lets change that. That will help with the more aggresive tuning and since the engine internals are being changed, adds a little insurance to the block with misfiring and the like.
Then when you finish upgrading them, you're thinking.... "well now the drivetrain is up to speed- lets go for more power!"
Then the brake and suspension upgrade you did round 1 with the turbo install isnt cutting it, so in go some bigger stoppers and coilovers.
Ah ****... but now the rims dont fit. No worries, Compomotive make some rims that'll fit.... and plus they'll be much lighter. Sweet.
Since we are saving weight, lets rip out everything inside (backseats, lining, audio gear etc) and change 2 front seats to lightweight race versions.
And before you know it, you've spent way more on the car that you ever thought you would- and need to spend more buying another car as a daily driver (because unless you can see your modified weapon 24/7 you arent parking it at some railway station or shopping center). So now you are maintaining 2 cars.... a POS you hate driving, and a weapon that you love driving but cant. As an extra kick in the nuts, the money you spent could have bought a brand new car that with a few simple mods could be just as quick but worth 5 times as much and still be more comfortable to drive every day.
Then you got insurance and engineering hassles.
Believe me folks.... dont do it.
Dont start.
Because more serious car modding is like cocaine.... once you start its a very slippery slope down. Doing little mods like exhausts and stuff is fine.
But strapping on turbos and superchargers.... oh man, you get that extra kick and you ALWAYS want just a little bit more.
Economy = SIDI.
Power = V8.
You want power (and then potential for force feeding on top), start with a base car more suitable.
The money, time, headache, and yes even a little guilt you save by just swapping cars will be HUGE in the long run.
I'm not a V8 owner. Never have been. But I've flogged the crap out of a car mod wise that had no business doing what it could do... and whilst the experience was heavenly, what I could have done with that money instead would have been even better.
Dont do it.
You want more power from a 6, sell it and get an 8.
It'll be cheaper, it'll be worth more, easier to insure, more reliable, and as a side benefit wont stick out like dogs balls at a carpark.
Yeah yeah... I know the arguements, "but I want to be different!". "I want a 6 that'll beat an 8!"
Sure.... but are those bragging rights really worth it?
Who you trying to impress?
