888 will stay effective a lot longer with heavy track use The AD08 is a brilliant tyre and much better than pretty much any other road tyre when used on track, but it is still primarily a road tyre that can be used on track. The 888 is a track tyre that can be used on the road.
When you do get the 888, get out for a short session first to scrub them and get some heat in them, then come in and let them cool down. A couple of cycles like that will make a big difference. First time out on brand new 888 they feel like wet soap, lol, but fear not
i fitted a de cat on an ep3 years ago and it actually lost power and felt slower, came straight back off again! either that or needed mapped to benefit.
Air flow really does seem to do these engines no end of good, even na.
It will need a remap so do it all in one go - intake, exhaust, etc.
Air flow will help the vtec point a wee bit but not all that much. Mine is around 4.7 I think and that really is the limit. We were playing around with different settings and you can't really go lower than that. At least not na.
But no matter - when you have a rock solid screaming banshee 8k+ available why would anyone ever use less than that
Main thing with decat for me is they do get very noisy. I have a race cat on mine, seems to be the perfect middle ground. And no issues with MoT (cat not present) and all that either.
I use a 3" on my B20, it loves it. Interestingly I had it fitted when I still had the B16B on the way to get the B20 and it destroyed all the power on that, but for the B20 it makes a lot of difference. Can't see a K20 not also benefiting from it.100% man. Interestingly the American's rave about 3" exhausts on the K20 / K24 engined cars. Which would generally be perceived as a little large... So they really do want lots of flow.
mmmmmm.... that all looks expensive! things just got serious! lol
Should be a very nice power plant when it’s all complete
I like that you have decided to improve the K20, the K24 is great for torque and power but having to keep the revs down isn’t for everyone
Are you building the bottom end yourself and have you decided on who will do the machine work to bore the block? I used Comiskey to bore my last block and the finish was very good
Hopefully so. It should be reliable too. Well I hope...
I haven't decided on who to bore the block. I would ideally like someone to bore the block, check the crank, line hone, build up the bottom end and of course check the piston to valve clearance. Then of course check the VTC, I believe it may have to be limited to around 30 degrees. I've a brand new VTC gear so the likes of CPL can physically limit it.
I'll give Comiskey a shout to see what they say. But I would prefer to rely on a Honda specialist that can also advise on the gaskets and other quirks that may come up...
I'm not quite at that stage yet though. But my current train of thought is to lift the engine out myself. Then take the bottom end and new head to get sorted in one package.
