Anyone have any experience with FI on these cars? I know the ecus are a pain in the *** but looking at doing some real power mods to my AWD F sport. Anyone know how the car would react with a 50-75 shot of n2o? I know the CR is a little high on these motors, but they also have over 1000cc of fuel between the direct and port injectors. Also thinking of a single turbo system. I know there is a supercharger kit for 6k and that only nets 350whp. Not a huge payoff for that kind of cash.

I too was looking but came to the conclusion that if you wanted any decent power the only way to go was the GS-F. But even then the GS-F didn't really feel like a ton more powerful to me either so a FI GS-F maybe is the key?

nice build, but 16k for just over 400whp is a lot of money. Thats basically 150whp more than stock. Thats over $100 per whp...

Yeah unfortunately if you're looking to make any decent power aftermarket, this platform is just the wrong one.

Yup, not a road I would go down personally.

Flexus85

yeah ill just drive it in comfort, i have a ls swapped mustang to make fun power.

I'm pretty sure 16k included his wheels, suspension, etc.
S/C kit is around 6500.

Don't do it. Pilotx put his up for sale for a massive loss, not a ringing endorsement.

Flexus85

yeah i got that vibe, thats alot with no real return. I mean i only have about 6k total in my street strip car and im looking at 8-900 horse. Thats total including the car lol. Its a nice comfortable car and it shall remain that way.

Plus GS-F feels like 70% of the weight is on the front tires.

I feel like that's how most of Lexus' are. The LC500 and IS-F both felt extremely heavy in the front around their little autocross course. Maybe I am expecting too much but considering their price tags I definitely expected way more than what I drove. I really wanted to like the LC a lot but feel like an AMG-GT is just a way better option for not much more money.
