supercharging aged motors, how high is too high?

As im also searching for info on this in tandem, i figured id ask as well.
my 01 tacoma 3.4L just hit 200k. did the timing belt, water pump, t-stat, etc. no leaks from any seals, no odd noises. still pulls strong.

My question is, i was toying around with putting the trd charger on it. i used to have a 4 runner and at about 76k miles, i put one on. i sold it with 170k , and it was just as strong.

But ive never put one on with such high miles. my next step was a compression /leakdown test. i know the 3.4's last quite a while, esp with regular maintenance. Anyone have/share similar stories or insight on this?

Thanks
Anthony

 

good to know some peeps are doing it at higher numbers

 

Given that everything else is sound, only concern I'd have really would be the lower end & these(3.4's) aren't known for rods sticking thru block or cranks snapping so go forth & S/C......

 

Try it out! If it did blow up you can sell the s/c

 

I had 157000 when i did mine about 8 years ago.

 

thanks guys. great to have this input.

 

My fantasy is to do this to my 4 banger that has 126k on it. We'll see.

 

As long as the compression is in limits I wouldn't worry.

 

I've supercharged other vehicles with very high milage. I just made sure compression was good and didn't run too much boost. Boosted a guys Integra that had over 200k, he's at 300k now and has had no issues. He also maintains his car better than he does his marriage.

 

aweseome. im gonna go for it.

 

I have 174k and plan on S/Cing mine. Thanks for insight

 

Boosted mine at 130K. Runs better than ever. Just make sure it's fueled properly with the SC and that it doesn't ping. If it pings, retard the timing. A properly fueled and timed 5vz with a SC should last just as long as one that's NA.

 

what are you guys using as far as tuning post SC?

 

This is everything you need.

ah was just looking at that before. Thanks a bunch!

 

Did mine at 160K miles and I am just at about 175K now on my '02 3.4 5spd... I also replaced the clutch at mine to make it a brainless swap. You won't regret it.
