Even if the cams made a difference in lope at idle, they still can't fail you unless they proved the cams were modified and the vehicle fails the 5 gas analyzer. I could blame the exhaust. They don't know. The cams certainly will have an impact on smog, but these should be just mild enough to still get by. Going the next step up to 272's would certainty fail. I've been down this road before in My C5 vette. Passes smog with the cam I installed and fully p&p heads. All I do is swap the stock intake and exhaust back in and disconnect the nitrous etc. I'm pretty good at selecting cams for smog and changing setups for test times. Really all these cams will do is allow a little more air in and out thanks to a duration increase. The drivability is going to feel the same, just a bit more power.
It'll be interesting to hear your thoughts on the difference with the 1UZ VVTi, and how it affects cam upgrades, since you would have now gone through cam changes in both a non-VVT (C5 is non-VVT, correct...?) and VVT engine.
It's an interesting theoretical exercise. Perception is that the 1UZ VVTi is tuned for respectable power, yet with an over-balance towards comfort and fuel-economy. This is where the VVT system could shine, if you could find a cam that gave great idle, yet with the VVT system gave the high-rpm overlap that would give great hp/torque figures. Yet that would involve balancing both a change to the cam and the VVT system, and that might be beyond what we can do here...
And here, we thought the Toyota TVIS system was a fun system to tune.
Not to bring this thread back from the dead, but I installed my BC 264 Cams and Tomei cam gear this week. I was SHOCKED at how much more responsive the engine is and how much harder it pulls. Definitely money well spent.
Heck ya good for you man! I love cams! Even mild makes a difference. They make the engine behave in a totally performance oriented way. I guess I must have posted results elsewhere after doing mine. I didn't remember this thread till now. My engine did pull and make power up to 7300 rpm with the 264s. Nice little jump from 6500 rpm stock. Never did dyno it till I went NA-T though. Do you plan to tune or dyno yous? I have no regrets going with the 264s either. Money well spent.
Probably both. The GTE has to wait 6 months or so since I lost so much money in the stock market the past 2 weeks.
I have well over $15K in parts on the way from Japan, I guess I will be ok until the stock market recovers. If anyone thinks I am bull ****ting on the price of parts I have ordered, we can do a little accounting over PM.
Did you tune yours with AEM Infinty? I would love the extra rpms.
I like the way the car sounds retarded 4 degrees, but it feels most powerful with the exhaust cam set to 0 degrees. Based on the butt dyno and experience from building cars, I would guess the cams are good for 15-25 whp and at least as much torque.
Did you see that I won the auction for the Abflug/Revolfe titanium exhaust?
My Aristo is at Revolfe right now and is currently making over 600whp/600lbft of torque with a T04Z and HKS 3.4 stroker on low boost. I am not sure of the exact numbers because they haven’t given me the dyno sheet yet.
They are about to install a V160 6 Speed Getrag, at which time Fujimaki or Mr. Mizota will refine it to 800whp/800lbft torque. The car is capable of well over 1000whp, but they don’t want to tune it over 800 because my number one priority is near stock reliability.
Revolfe Carbon Fuse Box Lid One look at an engine bay and you know if it’s Revolfe. It’s kind of a sleeper now. I am putting the full carbon Abflug side skirts, side strakers, and rear strakers on it. Revolfe Spec Do-Luck wing in the rear. The hood is being replaced with a Revolfe Spec Varis unit. The roof and sun roof are being removed and Pro-Composite/Mirage Auto Design (Mr. Uwabo’s new company) are replacing it with a one off full carbon roof.
LOL, I know your car is going to be a beast, but I was referring to the TrueGS300, I wanted to see if he actually went ahead with the NA build. curious to see what number he put down.
On a side note, when do you get your car from Japan?
I ended up going NA-T. Hit 405whp with the 264 cams and 7 psi. But the car is down for now. Been chasing 700-800whp and having tuning issues, plus I'm just taking a break from it for now. Other priorities.
lol
They did. Or rather they came to their own conclusions and decided to go turbo. This thread is old news, as you can see by the post directly above yours. Get back in your hole.

And clearly failed at it because they didn't take the advice given.
Tuning isn't just about slapping parts together and loading a base tune to get to a "goal of xxx HP".
