I noticed on XRU that Werty exploded his engine recently. Also, I read somewhere that the TRD supercharger has a service life of 60k or 100k miles? I know there are ways to prolong the lifespan of the device (changing snout oil regularly), but does the FI system have any business on a vehicle that one plans on keeping or running to 200k miles? I have 44k on my truck right now. What are the options and cost of refurbishing the blower when it's life is up?
Other questions, performance related:
1. Does the TRD supercharger require a re-tune if you put a smaller pulley on it for more power?
2. Can smaller pulleys be put on with little detrimental effects due to a stock exhaust system, or at most a cat-back (CA emissions being the reason)?
3. Are there any fuel system mods that need to be done for higher boost pulleys?
4. How easy is it to add a larger capacity radiator for the liquid-air intercooler, and is it really needed for a daily driver vehicle that will not be dragged? The only full power use it should see is while towing (2klb trailer), on ramp acceleration, and additional power for passing.
A lot of questions, but thanks in advance!
