New vehicle (maybe)

Well, I'm looking at a 1990 Talon TSI tomorrow that's running a "cyclone" engine? I would assume this to mean a 4g64? Is there any page out there for identifying the particular engine based on a casting number or anything?

I'll probably be doing a compression check on it to make sure that there are no lazy cylinders or anything, but does anyone happen to know off the top of their heads what the factory service hi/low limits are?

I'm mainly looking just to get something reliable since my other car is becoming more and more of a weekend cruise and car show/race car. Of course, I will end up dialing up a couple psi

Sorry to start out asking questions, I'll try to contribute content in the future

The only difference between cyclone engine and your 1g engine is that the cyclone name itself is meant for the intake manifold. It has extra butterfly vavle that stay open under low rpms to my understanding. Without the jdm ecu , you won't even be able to take advantage of the cyclone intake manifold. Most people just keep their stock ones, like my friend did and sell the cyclone one on ebay or something. The motor itself is the same thing as your 1g 6 bolt, same compression etc. The servicable limit stated by the repair manual is 122 psi, and its not a 4g64 , its a 4g63. 4g64's are the 2.4 litre motors I believe so. Yes, I know, I am the great one

Sorry, the 4g64 was a type-o (I sliced the crap out of one of my fingers working on my car last night

Okay, so the cyclone would pretty much just an electronically controlled dual-plane intake manifold in essense?

What changes are there to the JDM 4g63t's over their domestic counter-part? I've looked at some of the information I can find on JDM 4g63t's and they look to put out 210hp/215tq or something like that, but it seems difficult to find anything that goes over the internal differences.

the 210/215, is all in the ecu, the boost is probably raised, or some jdm motors happen to come with a 16g turbo, but that's like a 5% that you will have a chance of getting one of those, most just come with 14b.

Lord Paxin has a cyclone setup, and wrote an article on it: http://www.dsmtuners.com/forums/showthread.php?s=&threadid=67435. It seems like a good concept, not sure how much of a difference it makes though.
