How much would it cost and >were can I get it? To mangle an old racer's expression, "Size costs money. How big can you afford to go?" Commonly-available kits go up to ~96mm. There are probably other larger ones around, like 103mm, but they start getting pricey. There are stroker kits as well, but of course they require splitting the case to install. One question you need to answer is how you are going to feed it. The stock FI probably won't deal very gracefully with a 2.4 or 2.7 motor. Aftermarket FI tends to be very $$$, carbs somewhat less so. The stock exhaust may not be able to deal that well, so headers may be needed. The other question is durability. The bigger you go and the more power you make, the more heat you will generate. You have to be able to deal with the heat. There are also other durability issues, like added stresses to the various parts, even if the heat is dealt with. I know these are very nebulous warnings, but it's mostly just to tell you that you can't just bolt-on huge jugs and expect it to go. Check Mark Stephens High Performance. They've got a website, but the URL escapes me right now. Check on your favorite search engine for it. They have kits that go up through 2.7 liters at the least. Some of them have extra studs from the heads to the cylinders to try and keep the big high-compression motors from blowing out the head-to-cylinder joint. Hang on tight to your checkbook, they get expensive in a hurry. Particularly when you factor in the labor needed to install them. --DD Dave Darling 74 914 2.0 (decapitated) darling@simlab.arc.nasa.gov "OFF WITH ITS HEADS!"
