Hey guys,

Here's one for ya. My car's got 120k KM on it, (what's that... 80-90k miles?) if I put a turbo on it with around the same HP as the ballistics claims, is my engine going to complain and break? IE. Is it better to put a turbo on a relatively new engine, or does it really matter as long as it's tuned properly and you're not running insane levels of boost?

The general rule of thumb is, the tighter sealed the motor is, the less problems you'll have with blowby and power loss.

Let's be honest, these engines don't seal really well stock, so after 100K miles they really aren't doing great. Valve stem seals, oil rings and likely even the top compression ring are all starting to allow seepage.

Combined with just a mild increase in boost (6psi) and it starts causing problems. Pressurized crankcase, oil coming out the PCV valve, dipstick popping out, oil burning, et al.

You CAN do it, and it will work, but it doesn't seal very well and your engine performance and fuel economy will suffer -- compared to what would happen on a brand new motor OR way behind what would happen to a "built" motor.

I have 75k on mine and trust me blow back sucks oil thru the pvc, the motor runs great other wise, I'd grab a motor and build it up for a turbo, I think red can help you with both.

If the turbo kit you intend installing replaces the pistons and rings like the Ballistic kit does - (rings more improtantly) then you will basically have yourself a brand new bottom end (engine) and therefore no problems at all.

Itis a fact that the older the block, and the more heat stress relief it has had - the better - therefore the higher the mileage the better for a high powered application.

This technique is used by Cosworth and other rally teams that boost constant 30PSI under extreme conditions!.

My car had a blower kit installed on it as soon as i bought it. 0 km's/miles
It lasted 12 full months of drags every second weekend, and street races every chance possible.
It was running 10 psi and was tuned on a dyno.
If you tune for power there is always the chance it will brake a stock engine, because of the high factory compression.
But if you take it easy and tune about 30-40% more power then it should last as long as most other factory turbo cars.
Any extra power always is a compromise, your choice.

<img src=/images/forums/snitz/thumbup.gif width=25 height=18 border=0>Mo Powa = Mo $$$$ spent to make it reliable. Slap on a turbo just like that and watch the engine go to bits internally. Spend a little more on the correct parts and you'll have an engine that lives a lot longer...uhhh, and prospers?
