How to add 100 horses to my Lexus IS350??!?

[Marko]

It seems there are limited options for upgrading my 2006 IS350. While leaving this car naturally aspirated would be ideal, I realize that asking for 400-425 horses out of the stock 306 is asking a lot. Anyway, that is what I want, to add about 100-120 horses to my stock IS350 but there aren't any readily available kits. Or are there? You tell me.

Also, if there is indeed a supercharger or turbo available somewhere what other modifications would be necessary to ensure that the engine doesn't wear prematurely? Thanks!

Does anyone have any suggestions and could you please specify links if you recommend a product or service specifically? Thanks!

not worth the money and work to get 100 horses. Your best bet would be to swap engines.

If you're thinking of trying to squeeze that many more horses out of it, you better toughen up the inside...rods, bearings, bolts, the works. Getting too much juice will cause parts to go flying every which way. Not to mention heavier axles and joints...all that power's going to be real tempting, and stock stuff won't cut it.

Hook up 100 horses and whip 'em into a charge.
