4-1 or 4-2-1 extractor?

In the afternoon, I went to the 'specialist' workshop. I thought just went there to have a look to see if I has the luck to learn anything new. When I reached the workshop, he was busy doing his work. I saw a couple of MIVEC in the workshop. One of them was having an engine oil change and the other 1 was 'stripped' off. The 'stripped' MIVEC was changing the cam. I went to the back and saw the faulty cam. It was full of sludge. I wonder if the owner ever change engine oil. :P

Then, there's a Perdana waiting to change gear box. Don't have the chance to ask a lot about it. All of a sudden, 'specialist' came and told me that he has a 4-1 Type R extractor. I was wondering if there is any Type R Honda comes with 4-1 extractor. I thought all came with a 4-2-1 extractor. Maybe this is made for Type R engine. Well, it can be fitted to my Vtec, I supposed. Hehe..;D

He said that 4-1 will release all the power that the engine manage to produce. I wonder how? But I really interested in this extractor. Maybe I'll just install it, a couple of days later.

Sorry..as I did not take any picture. There will be pictures if I install the 4-1 Type R extractor. Hehe..:P
