Why go through the hassel of doing all that work when you can just upgrade? I'd rather spend that extra money on a brand new car.

 

1. Stop telling folks (like me) who want to create a unique is250 to "just upgrade"... we're not that dumb, we know that a 350 is faster.

2. I was quoted 7k from ARMA about a week ago. As much as I like boost, I'm thinking of fabricating my own kit or finding a relatively cheaper alternative

 

Amen!!!!!!!!!!!!!!!!!!

 

Just curios. Are these minor power gains due to the fact that some owners have kept their boost sub 5psi? If the boost was raised to 7psi, I am sure you can get 100hp or more out of it.

All you would need to do is inject more fuel into the system, which will eliminate the lean burn and help the car attain the optimal A/F ratio. If the mixture is balanced, in theory, there should be no mechanical issues whatsoever.

 

4000$ for my custom Rotrex C30-94 Supercharger (as Arma)

 

BTW there is a rotrex c30-94 on ebay right now that (from the description) looks like it might be getting sold by arma. This is S/C only, not a kit. You would have to factor in the price of the oil kit (which usually comes with a rotrex) and a pulley as well as all the other stuff (piping, BOV, brackets, intercooler etc.), but if you were thinking of making your own kit from scratch anyway, this might be a place to start.

 

Thanks for the heads up... at the moment im working on ordering some aesthetic-based pieces for my 250.
Gotta save up!
