personally, given the financial resources, i'd spend the money on cylinder head work instead.
yes, you will get a few extra CC of displacement, but you also decrease your rod:stroke ratio; as someone else already said, this is bad for revs, and the general reliability of your engine at higher RPMs. in short, any increase in power resulting from displacement will be offset by your new lower redline, unless you spend a pantload of money on the kind of pistons/rods that can handle it, and even then you're still dealing with a less-than-optimal setup... not to mention that dropping $2-3k on a forged bottom end rebuild would be a *very expensive* way to get those few extra hp, and you'd want an air metering system that didn't involve a HUGE PLATE blocking the air path as well (as there's no point in increasing displacement unless the rest of the engine can handle and use the extra airflow)- ready to pony up another couple grand on aftermarket EFI and tuning? (no, i am still not a fan of motronic, or really any engine management system VW used on the A2s...) so yeah. long story short, it can be done (from what i've heard), but it's not the easiest or cheapest way of making power- there are (at least a few) other areas of the 16v that need to be addressed first before increasing stroke. all of this is IMO, coffee just kicked in and i've been considering the aspects of building a hardcore all-motor 16v, so i'd thought i'd ramble for a while... --- white.rabbit _when i am king you will be first against the wall_ 1987 vw gti 2.0-16v motronic/wolfsburg (yay, it's special) 1988 yamaha ysr50 (in progress) --- ----- Original Message ----- From: "jassem" <[email protected]> To: "16V" <[email protected]> Sent: Saturday, August 11, 2001 10:11 AM Subject: What's with this TDI crank? > It seems there is a 95.5mm TDI crankshaft that fits our 16V engines.
