good stuff alex!
you have to look at the big picture, Simon.Scuffers said:Oh dear.....
there are more inacuracies than you can shake a stick at!
Just from page one,
197PS - Err - NO, it's quoted by Honda as 200PS
Cast Iron Block - Err - since when is the K20A's Block cast Iron?
No mention of the JDM's having different CR's to EU engines
FFS, you would think that if you were going to publish an artical like this you would do the reasearch and get the details correct...
It's depressing how much b0ll0cks is published these days..
Not the point,nikos said:you have to look at the big picture, Simon.
The K20 again uses an open-deck, die-cast aluminum block with cast-in iron cylinder liners
The people writing these articles are journalists. A while back in hondatuning here in the USA, they wrote that you can use a s2000 head on a K series block.. but these are really details.
The fact is that hondata k pro has been proven more than enough. AS you also noticed CPL racing who is behind this article is one of the biggest if not the only hondata dealer. I was told in greece that K pro sells for around 1500 euro from CPL.

At that exige site I read a thread about you. You are famous man!! Thread is called "scuffham and his attitude"
They're cast in not pressed in. They've been cast in since they started making Aluminum blocks. A mold is used and the mold holds them in place. If you saw one of the sleeves out of a block you would realize there is no way in hell you could press one in without damaging the aluminum.Scuffers said:sorry, but if you read thouse links, you either get that they are cast-in or pressed in, now, how the hell do you 'cast-in' an iron liner to an ali block?
pressed in makes more sence...(I am 100% sure thats how they are fitted).

I'm not sure. In Aug I went to the Honda plant where they make the V6 and D17 engines, and I'm sure I saw raw engine blocks without liners. There was an inspection stage at which the reject blocks had no iron and could be recycled easily. After the liners etc it was harder to recycle the blocks. On the other hand, I remember that the B20 had liners with a pattern around the back which must have been cast in. Don't know how you'd stop the aluminum shrinking back as it cooled. But then, there was so much stuff that it was hard to focus on one thing when you're rolling past complete skips of rejects heads etc (send some our way!). The engine blocks were cast under a lot of pressure - many thousands of tons. Other interesting things we saw was the machine to insert all the valve seats at once in about 1/4 of a second, a machine to bore and tap all the holes on one face of a cylinder head at once (in about 1 second), a machine to measure all the bores in about 20 places for taper and out of round to high accuracy. It was an interesting visit. The only sad thing is all that material and effort being put into D17 engines - it seems a crying shame since the D17 is not a great engine.They're cast in not pressed in.
I think the good for 400 was an accurate statement had he got the part right about the alloy block. Stock block and 400 hp seemed fairly sustainable in my experience with our first turbo car.Rubber Chicken said:Back to the article - good article, if not a surprise to us. Guy @ CPL does a good job and deserves the credit. As far as accuracy goes, everything about Hondata was fairly accurate. Just a couple of slips like the K20 iron block.
Good for 400 hp? There's a couple of people who have broken 550 dynojet hp on the K motor, and the block has to be good for 800-900 hp. Still got a way to go to catch up with the B - talked with someone today making 840 hp with a small shot of n2o.
Edit: confirmed that the liners are cast in.
As for the top potential, I've talked to someone recently claiming 1100 hp. I have no reason to doubt him but he doesn't want to come forward yet. His car will start hitting the track around February.
