87Red

I have a question. I am thinking about doing the turbo conversion from 2bennett. My question is, since my 87.5 already has the 2.3L, will they still need to swap the engine with the 5000t? Has anybody done the turbo conversion with 2bennett? Are they relieable and perform clean work?

Sorry I guess that was more then one question.

A ripoff basically. But hey, if you have the money and don't want to do any work yourself go for it!! Im sure they do a good job There are some posts about them (just search)

I don't know anything specific about 2bennett, but my perception is they are expensive.

The compression ratio in your 2.3 is WAY too high for a turbo engine. While you can adapt a turbo to the 2.2, it's still easier to get an entire donor drivetrain from the 5kt.

Swap your car with someone who has a 2.2. They will love you for it.

There are lots of turbo cars out now with 10:1+ compression. Take the A4 and Passat, or any car with a 1.8T for that matter. The 1.8T is a high compression engine that uses up to about 1.1 bar of boost with aftermarket chips. Stock it uses .5 bar. So, with proper engine management (such as real EFI and knock sensors) I just don't understand why you couldn't runs a fairly small turbo (like a K03) at 6-8 PSI. Can you explain why it can't be done?

The 1.8T runs at 9.5:1 compression, and the reason it gets away with this is, mainly, spark plug placement. They've found that by placing the spark plug in the exact center of the top of the combustion chamber, you get almost 100% burn efficiency, with almost 0% chance of preignition. This, coupled with 5 valves per cylinder(also a huge help) and much more sophisticated engine management(older versions just wouldn't cut it), allows higher turbo compression ratios.
