I'm just wondering how reliable your cars are with turbos in them. Generally how long can you expect a turbo to last on your car, with a moderate ammount of boost, and a moderate ammount of usage. It's said that the car will last just as long as it would N/A if you keep the proper fuel/air ratio or something, but I highly doubt that to be true. The turbo is definately gonna put more strain on your engine, and I would stupid to belive that the engine would last as long as it would N/A.

 

Will last as good as N/A if you keep safe boost.
More stress will most likely wear things faster like the clutch, tires and stuff.
But thats normal.
I cant use my example with my protege because I overboosted 20psi and maybe injured the piston rings.
But, it isnt that bad, the car still runs normally after that, but, I think it will soon fail on something if I stress it too much.
I am just upgrading the clutch, intake mani, exhaust, mounts and other stuff and decided to open the engine and fix that.

 

well i know plenty of people driving around in turbod 2gen Rx7's, i think thats around late 80's when those were made. From what ive read its not strain like people say nitrious puts strain on your engine, if you have everything set up right and you dont go over board i would imagine it would last exactly the same. But to answer your question, i would say going on about 13years.

 

mine has been boosted since last september....and i have put over 15k miles on it since, daily driven, road trips, traffic jams, drag racing, street racing, cruising, u name it, that cars been thru it.....its running as strong as the day it was boosted, and driveability is as good as when it was stock.....its about to get more done to it, but as of now, id say this thing will be here to stay for a while......btw, the motor is still the stock motor NOT designed for boost

 

one common problem with aftermarket turbod engines seems to be their ability to break the stock tranny.

in cars known for having weak trannies, some car shops recommend keeping the stock clutch if the car is turbod. the idea is to deliberately make the clutch the weak link in the chain, instead of the tranny.

 

This is true

 

Yes, I agree that it's cheaper to keep the clutch as the weak link, however I worn out my stock clutch pads within 3 days after I turboed my protege due to the constant clutch slippage.

Also, why turbo charged your car if you do not fully utilize the full potential.

 

29,000kms so far engine is still in great shape and should last a long time at moderate boost

 

3 days?! what kinda boost was it running at and how hard were you driving it?

 

Using a stock clutch, but running 1 bar boost at 190whp at a T28 previously.
