Ok iv been reading up a lot lately on turbos and how they work. I also tried to search this but couldnt find a previous post.

What is the most boost you can run on a stock 2001 engine. Iv been reading that 7psi is a safe number, but that was on shmondas. The reason i ask this is because id like to keep my tib for another 3 years or so and i dont want to blow the engine before then. I may get cut up for this but id really like to know what a safe number would be and an estimate on the number of miles ill get until my motors done. I have 47k on it now. So thanks in advance.

 

I think Speed Factor is running 17psi if I'm not mistaken and Captainsly has 12.

 

PSI is a general term. What turbo are you going to run? Different turbos run different PSI... you might need to do a little more reading. lol.gif

If your talking a T3/T04E like whats with Speed-Factor, then about 5 PSI non-intercooled. About 7 PSI intercooled with stock fuel system. About 10 PSI on stock internals with upgraded fuel system.

If you know what you are doing (which I doubt right now) and keep an eye on intercooler efficiency, EGT, Air/Fuel, etc. and don't abuse your engine or have abused it. Then you could expect 80% of the life it would have had non-turbocharged. I.E if it would have lasted 100k miles without turbocharger, than 80k miles with it.

If you have no idea what your doing and have someone else install and tune it, expect 5k-10k miles out of your engine before you screw something up.

 

It also depends on how you run your car..if you run it hard often, eventually it will catch up with you..

 

Drop the compression with some new pistons or a decompression gasket and you will be safe @ 200- 250WHP range providing your car is tune correctly.

I put 10,000 KMS on my completly stock engine @ 10 psi of boost on a T3 turbo. Around 200 WHP range. Engine looked excellent when I tore it down.

Cuda-Turbo has over 20,000 KMS on his engine with the compression droped with a decompression gasket. And he to is also in the 200WHP range.

 

Hey thanks guys for the info and direction. Yea i dont know THAT much yet, but iv been reading a lot and talking to some people that have turbo cars. I figured no matter how much boost i go with id need to upgrade the fuel system, so that is know problem.

About the type of turbine, prolly a T3 or T3/T4. I have a guy who will sell me a T3/T4 for 100 bux. I trust him thats its in good condition so rebuilding shouldnt be an issue. But i am unsure of what would be the safest and most effecient for my stock engine. Like i said i want to keep the internals stock.

Now that i know i will most likely get 80% of my engine life with low boost, i am gonna go turbo for sure. I still have more to learn before i buy everything or try to install it, so any other suggestions would be appreciated. Thanks

 

If you've heard it once, you've heard it a thousand times. Buy Maximum Boost by Corky Bell. Read it... then reread it five times, then read it backwards. Then you will know what you need to do to troubleshoot a Turbo, build your own turbo system, how to install an aftermarket one, which parts will work where, the best intercooler size and flow to maximize efficiency, enough formulas about turbos to blow your mind, and how the turbo works internally.

 

Yea i knew it was only a matter of time as to when i was going to be told to get the book. Im going to florida next week to visit family, so im planning on reading it on the flight.

I do have a question though. I have to decide if i want this T3/T4 turbo by monday. It should be in good working condition. Do you guys think it is worth $100 with a stock intercooler from an eclipse. I dont know enough yet to decide if its worth it. Any help?

 

Are you talking with all the piping or just the core? Either way, the Side Mounted Intercooler sucks. I doubt that the piping would fit, and the piping isn't very high quality. If its a second gen, the intercooler piping isn't even aluminum. The core isn't very good either. I would passs it up and buy a Front Mount Intercooler made for our cars with more than enough cooling abilities for what you're trying to accomplish. If you want the engine to last, you need to avoid heat at all costs. Heat in in the intake charge is a contributor to detonation, more wear and tear on engine parts, and lost performance.

 

He has an aftermarket T3/T4 with the side mounted intercooler only. That is all he has. Like i said, i still dont know specifics on what to do. But couldnt i just mount that intercooler in the front? If everything im saying is to "N00b" sounding, then ill just buy it and read maximum boost in florida and ask questions when i get back. Its just that i thought i had somewhat of a deal here and thought id ask anyway.

So if you dont mind dealing with my ingnorance of turbos for the time being, let me know if it worth $100 and if the T3/T4 is any good for our tibs. thanks
