Arrow Turbo: Worth it?

My 85 se currently has about 117,000 miles on it. The engine has run just fine as long as I've had it (few months).

Is it worth it to put the extra strain of a turbo on the engine with this many miles on it? Or do you guys think it'll most likely kill my engine after a short while?

Opinions?

Well if you are gonna run a decent sized turbo then you most likely would want to go with some type of porting, such as a streetport. Believe me it's worth it, and to do this you would have to rebuild the motor anyways. It's hard to say how your motor will react to it's newfound strain. It all depends on how you plan on driving it and what type of abuse it takes. The average life of a turbo motor is less than 90,000 at best. If you are going to invest in such a turbo setup and spend the money to do so, why not go the extra mile with a fresh rebuild. It wouldn't be so nice if you slapped a turbo on a stockport motor and then miles down the road an apex seal popped and went straight into your turbo's impeller, destroying the turbo and costing you even more money.

I am in the process of replacing my Stock 12A carby with a 13B 6Port Efi engine, according to George at Pac performance in syd (he builds 1000Hp+ rotors)
a 13B 6 port EFI will produce more HP at the rear wheels than a stock 12A Turbo.

to quote his numbers, as he told me, Stock 12A carby = 70-80 Hp to rear wheels,

stock 12A turbo = 120 Hp to rear wheels,
13B 6port EFI = 130-140 Hp to rear.

I have installed a 12AT gearbox to replace my old blown one, as they are built stronger and will take a 13BT power easily.

I had 180,000+ miles on my SE when I stuck a turbo on it. It'll run fine as long as it's tuned right and and you don't floor it to much. You can always rebuild it later.

That's what I was thinking. I figured a rebuild would be a good idea either way.

I don't really drive my car real hard, I've gone past 5000 RPMs very rarely and almost never floor it.

EFI means electronic fuel injection

Well when you go turbo, it's pretty much impossible not to go past 5,000 rpms.

If you never take it past 5k, and rarely floor it, that why do you want a turbo.
Sorry dont mean to sound like an ***, but it is confusing me some.

Electronic Fuel Injected, I don't know much about the meaning, but I've heard mixed reviews, some people like it, some don't, and I'm stuck in the middle not really knowing anything :P

A basic explanation of what EFI is: Each fuel injector recieves electronic pulses which will help it determine how much fuel to spray and when. To get such a signal, various sensors are used throughout the car which affect what type of pulse the injector will recieve. A good example of a sensor that effects the fuel injectors is the oxygen sensor. The oxygen sensor measures air/fuel ratio of the exhaust gas and then emits an independent signal to the ECU or computer. A strong O2 sensor signal may cause the motor to run rich, and a weak one will cause it to run lean. The ECU reads the voltage of the signal and compensates by controlling how much fuel the injectors dunp into your motor. I can't explain everything right now but I hope you get a decent idea of what EFI is/does.
