That's pretty much it. Basically those cams are never going to produce any decent power in a B20 with stock compression. It's not just Performance Autoworks saying this, Toda themselves have stated that the cams need high compression and high revs to work properly. The fact that they are 2 different specs of cam isn't helping either. Another thing that isn't helping is the intake manifold, apparently it would be great for a turbo installation, but not the best in an N/A build.

A guy who is well known in Honda circles (Perrymoo for those Honda bods on here who are wondering) has backed all this up, I've just come off the phone to him actually.

and why did this only happen when you got it, did something change or ?

The car had never been dyno'd before, so it was likely always the same.

Basically, yes.

Like I said before, it never really felt like it had a big VTEC kick, but I put that down to the 2.0 bottom end giving more torque when out of VTEC than the stock B18, thus making the changeover less noticable. That was obviously never the case, the engine has clearly never made more power in VTEC.

That's not to say Si was to know, because even the way it is at the moment the car doesn't exactly feel slow, so without the car going on a dyno there was no way to know.

forgive the ignorance, but the "mismatched components" diagnosis makes it sound like the thing would run like a bag of spanners

but it doesnt.

Only on VTEC when the radically different lobes come into effect ;) The flow characteristics of those two cam profiles simply dont get the air in or the exhaust residuals out aswell as they should, hence low VE and lower output, not really related to running like a bag of spanners at all. Si did you ever have it rolling roaded when you had it? I hope you weren't geting mega excited over what was essentially a stock teg :P

Did he actually make any more sense on the phone than his forum post ramblings do?

well at the end of the day, it goes like stink, so how was anybody to know

it just doesnt go quite as well as it could, had the original tuner chosen better parts. Least you've got you're car back now while you figure out how to sort out his mistakes :)

See above, to my knowledge the car has never been on a R/R. I have the copy of Honda Revs magazine here with the feature on the car after it was originally built, and Ray (the original owner) doesn't even mention any figures.

Damn m8, making me wish I had it RR'd now. I was honestly *this* close to doing it too before sale, sorry I didn't dude I would never mislead you in any way :(

But like you say she goes well enough, so much so that I thought it was fine (felt about as fast as my S2000 give or take). Must have been some actual torque in a Honda masking my senses :D

Most odd though
 
Many people have made mistakes tuning Hondas. No blame attached to Si - he'd never have known he's bought a great car with a jumble sale engine, to an extend you just expect people to have done their homework. I researched hours every mod on my Teg & made sure I was doing the right thing. I spent a week deciding on geometry settings alone.

Boy are you in for a surprise when vtec really kicks in. :D
 
M3's don't come to life till about 110mph really.

Lightweight DC2 with 250bhp would pull a gap I'm quite sure.

Well, up to 110mph, then of course the M3 would
**** on it, but we don't talk about that minor technicality. :p


Star out swearing. FF.

I so wish.

I must own an NSX before I'm too old to get in and out of it without looking an arse.

I've tried and I don't fit. I'm gutted. :(

They say it will get easier with each day that passes, but it doesn't. It's just one big downwards spiral :(

Thats quite possible, with 280bhp I was pulling infront of an E46 M3 when we started around 70mph and he started to reel me in and was side by side around 125mph when he then started to pull away.
 
All about weight up to 100mph. Then it's all about grunt.

You should see what happens against old M5's! You're close to them, then 100mph comes along and it's like you've just opened a parachute - they just vanish. :eek:
