A friend at Toyota/Lexus corporate told me that the only way to get rid of the problem of detonation was to bypass the VVT-i. He said there was a way, but my check engine light would be on all the time. I was just wondering what you all were doing to solve this problem?
Jeff, with the SC300 informend me that the VVT-i was the cause of my motor blowing. Toyomoto & Toyota Corporate backed it up.
This should be something that everbody is made aware of. I only had a turbo on for 5 months and my car was a 98! I never boosted over 1 bar. I am very interested in any info you may have.
Thanks

the OBDII and boost are a bad combination with the factory ECU controlling everything......i cant say for sure thats what blew his motor but i have a feeling it had something to do with it......this is the reason toyomoto uses a haltech ECU to control everything...the VVti remains in place but it controlled by the haltech to prevent detonation......from the info i got .....if you remain with a factory ECU on the VVti with turbo your gonna have issues......so haltech is your best alternitive Jeff
p.s.-none of toyomoto's is300turbos have any issues with timing or blowing motors even with the vvti

well I talked to Cort the person who made this post and he mentioned the he did the turbo kit himself and it ws never tuned nor does he have a AFC of any kind.. hence I think it might be a A/F issue...??

Also, i agree too, a huge part in forced induction is A/F.
Has anyone opened up the motor to see if it was detonation? It might have gone lean and then blown up the motor.

Oh and Cort, I think I met you at the A'pexi sale. I was the guy that is turboing the camry .
Anyways, I just got someone that might be able and willing to help you. Talk to Eric over at EL Prototypes in Azusa. He might be able to help you out.

Call them up (but sometimes, they don't pick up their phone) or go there. Eric knows A LOT about the vvt-i system and forced induction.

Hey guys!
Thanks for all the feedback! How would I be able to tell if detonation caused the number #6 piston rod to break?? I pulled the head and the pistons and the chambers look all the same. I rotated the crankshaft and #6 didn't move, that's how I came to the conclusion that I broke a rod.
I want to figure out what went wrong, becuase my new TT blcok comes in tomorrow. I don't want to make the same mistake. I'm going to have the car tuned right away this time :-) I'm also thinking about disabling my VVT-i. I have a friend that can do it, but I will have to get use to seeing the check engine light.
For your info my Supra has the exact same VVT-i VR2 Motor as the IS300.
