Will be interesting to see cam specs, I had a quick look through the FSM but it didn't really have any helpful info that I could see regarding lift and duration.

Hmm well I think these are valve lift figures at least for export 20G/JDM 20D cams. Going off FSM STD data. Looks like the rear valve in each cylinder has higher lift than the front which is strange?

Intake
Front
Lobe Height 39.41-39.51mm
Journal OD 30.946-31.963mm

Valve Lift 8.464-7.547mm

Rear
Lobe height 38.88-38.98mm
Journal OD 27.946-27.963mm

Valve Lift 10.934-11.017mm

Exhaust

Front
Lobe Height 39.41-39.51
Journal OD 30.946-31.963

Valve Lift 8.464-7.547mm

Rear
Lobe Height 39.41-39.51
Journal OD 27.946-27.963

Valve Lift 11.464-11.547mm

That's far from unusual, VVL engines typically have huge variances on their low lift cam, it induces swirl at low RPM which improves charge dispersion and combustion
[20:30:58] <Pelvin> what are the handbrake shoes? are they only fitted on the rear?

These aren't VVL engines though.

Hence the variances not being huge

It's not unusual to have cam lobes different lift and even different timing and duration.

Interesting, not something I've come across before. Tried having a look around for JDM cam specs or a Jap service manual but couldn't find anything :/ Really keen to find out if GT or RS cams would be a worthwhile upgrade to my current ausdel engine.

Updated the sheet with BC/BF, and BD/BG non turbo specs, for anything 2L and up.

Never realised the EJ22 was so short lived in JDM land, BF7D, and BG7A only! This could mean any NZDM 2.2GX made after 96, might very well have the single port EJ22 like the states! Would love to find one and see, those Pistons have dual valve reliefs, so DOHC heads work flawlessly on them.

Also on cams, found the solid lifter cams and the direct HLA cams have the same journal sizes, but the lift on the Ol BG5A/BG9A is waaaay more than the solid lifter heads... Very interesting. Add this to the fact you can't use thin headgaskets on the Direct HLA blocks... Is that because of the higher lift? Hmmmm.

<Shale>: Blighter doesn't really have an accelerator pedal, it's more just a loudness pedal. You can change volume, but you won't go any faster.


<mjlqtown>: (Southern US accent) I'v excised the demon! This car is now clear!


<Reuben>: I feel like when you stomp the throttle in Blighter, it's like you've startled an old man!

Big update, sheet now called "Legacy Engine Specs", covers ALL engines in Legacy's from 1989 to 2008 now, including 1.8's and 3.0's etc. Did a big push to get the non turbo stuff done. There's some nice surprises in there. Even went so as to look through trade me, and pop a whole heap of vins in fast, to find out engine suffixes for the non turb's. EJ201, EJ202, EJ203 etc. Found out that the the reason the 3.0R EZ30's are referred to as EZ30R's, even though they are still an EZ30D, is because in the advertising material, the Name of the engine is "EZ30-R", but the engine code is still EZ30D. Same for the DOHC EJ204, they called it the "EJ20-R" (I had always assumed the community had dubbed it the 30R because the car was a 3.0R)

Removed the "MY" from the year, and put a note up top explaning years used are release year, and NOT model year.

Check out the 2.0R motors from the 4th gens if you're not familiar with these things. Quite a hot wee engine! No wonder they were no end of trouble in NZ when run on 91 and 95 octane.
11.5:1 Compression, 190hp @ 7100rpm for the manuals.
