huge performance aftermarket for these engines, but is there a RWD transmission that will bolt up?
you might find these engines rotate the wrong way,if the gearbox is on the right (veiwed from drivers seat) its spins the wrong way and there is no
box for it
Honda S2000 gearbox should bolt straight up.
Conrod, I think they have changed the rotational direction now.

nice looking - who mentioned that ? great engines , thats about it .
the k20a civic type-r engine is great, especially in jap spec (used for race engines) as they are 220bhp instead of uk 197bhp. gearbox would need a
bellhousing to fit a quaife type 9, mt75 or t5 box..

I always though the vtec engines were great until I had had a 2.2 prelude for a couple of years and it really started to get on my nerves. Initially
the kick in the back was great but after a while I stopped viewing the power curve as being strong with a big peak at the top end but as normal curve
with a big hole in the midrange, got bored of it and gave it to my wife. I ended up with a car with less top end power but more mid-range power and a
more linear power curve with I prefered (and still do).
Each to their own though and the vtec engine was utterly bomb-proof over 3 years in all and something like 60k miles.
Having said that we had an old civic with a 1.6 16v twin-carb engine and that was a belter of an engine albeit a bit underpowered in a civic.

i took 2 test drives in a type r and there was no power hole. the car was decently powered to 6k, then all hell lets loose.
the dealer told me its got a 3 stage cam - changes at 4k and 6k

The major downside in my opinion is that when that opportunistic overtake is available you nearly always have to change gear as you cannot possibly sit at 6krpm mile after mile. If you want economy and performance then it's a great design but if you just want performance and the responsiveness inherent in that requirement I found it lacking. Each to their own though.

something definatly switches in at 6k - its VERY noticable.
I had a rover 600 for a comapny car a few years back - so I know a bit about accords - it was based on one.
the type r:
Id guess that if you didnt go above 6k power point, the car would still better 10 secs by some amount, which is not unreasonable. Its certainly not
like the majority of family cars and hatchbacks with 12 - 14 secs performance to 60. It doesnt feel like you have to go above 6k. In fact if you do,
the power comes on with a real rush, and wouldnt be useable in town.
Its a more than adequately powered engine up to 6k, and like someone pressed the nitrous button once you hit 6k.

the engine not only varies the cam timing but it also varies the intake chamber length with the manifold/throttle body, very trick. this helps it get
the torque lower down i believe.

read this on how it all works:

quote:That's where the vtec cuts in. You can change it to cut in where ever you like by changing a setting in the ECU although I think you have to have an aftermarket ECU fitted rather than modifying the factory one. My prelude kicked in at 5200rpm, it was a japanese import and the cut in rpm was different from the uk ones. The trick when driving them hard is to rev them to the red line so that when you change the engine is still in the vtec range to give you maximum acceleration. While that's probably obvious is still amazes me to this day how the engine in the prelude stood up to two years of me reving it to the red line before changing up pretty much every time I drove it. It's an incredible engine in pretty much every respect except that I don't really like the 'step' characteristic of it (I'm afraid I'm not keen on turbos either for the same reason). The only downside I found with driving in the vtec zone all the time as I tended to do (well, nearly all the time) was that it was quite noisy, used oil (checked with honda who said it was normal and top it up - my 944 uses more oil in normal operation is it wasn't as if it used loads of the stuff) and the fuel economy was attrocious (as you'd expect). After I gave it to my wife who used it as honda probably intended, ie. use the vtec zone every now and again rather than all the time, it used no oil and returned over 30mpg... very clever indeed.

. I'm not entirely sure but I think all the new i-vtec engines spin the right way, but
they'' be expensive. i found on my test drives i was doing the red line in first and 2nd and 3rd, then shifting to 5th (as the dealer pointed out!)
I was expected to conduct the test drive between 6 - 8k by the dealer that was with me!
Thats not how I want to drive a car. Its nice to have it when you want it, and not be forced to drive like a looney cos the engine wants it that way.
Thats why i thought the low down power was decent too.
the variable intake geometry thing was also on my mazda 323f zxi 2 litre 24valve v6.
what a mouthful
