NA IS300 5MT or NA G35 Coupe 6MT (Daily driver/track build)
Greetings everyone. I have been plagued by a dilemma and require your expertise and opinion to resolve. Before you flame me, I will remind you that I've invested countless hours learning all that I could to help me figure out a final solution - I am here to purely seek out your opinion and guidance as to what you all think my final move shall be.
Brief background and ask:
I'm an avid car enthusiast with much of my car ownership history being tied to Japanese cars (95 Nissan 240sx, 01 Lexus is300 (auto) 03 Nissan Maxima 5MT, 99 Acura 1.6EL w/ b16 swap, 00 Acura Integra GS-R, 92 Lexus SC400 and finally my 08 Lexus ISF, now sold).
I'm itching to build a car that is both streetable and also a weekend track warrior. The car will spend the majority of its time being a street car however I'll be taking it to Toronto's Mosport at least 5-6 times a year. Having owned an 01 IS300, Auto with LSD, I fell in love with the relative lightness of the chassis and the pure silkiness that is the 2JZ GE.
I've seen countless NA-T and GTE swap builds however I want to remain NA for as long as possible if I go the IS300 route. I know the car can handle its own with proper suspension and tire set up along with improving throttle response by completing a few mods (clutch damper delete, throttle body mod among others). The car is also practical with 4 doors and proven reliability. That said, out of the box the car isn't the most powerful. Staying NA will obviously limit the overall power I can extract from the car however I want to maintain a budget and also reliability, thus wanting to adhere to NA only. Although the IS300 is still a contender for me with this power constraint, I have been toying with another option as well.
This brings me to the Infiniti G35 Coupe 6MT. The only Nissan product I've owned is an 03 Nissan Maxima 5MT - great car with the awesome VQ motor. Pros: Power, torque, looks great and is relatively problem free. The 03-04 came with brembo and didnt have too many oil burning issues as the rev up motors did which would be what I would look for.
Cons: heavier, and even though 03-04 did not have too many reported oil burning examples, it is still a possibility. Not sure how the engine and tranny will stand up to track use under full load for 15+ min runs at a time. I know the build quality is nothing like lexus and I say this having owned the IS300 and my ISF with MILEAGE on them. you can feel the quality of those cars by simply closing the door and hearing that solid thunk. This isn't to say Nissan/infiniti does not make good cars.
The G would be newer in year (slightly), with better looks (IMO), and most importantly, will provide a heck of a lot more HP and TQ along with a 6MT gear box vs 5MT for Is300.
In your opinion (as unbias as you can make it), what would your opinions be towards building a street/track car between the two options?
I appreciate any and all feedback!
