Hey my engine builder was telling me to try and find some UK Accord Type-R (edited not ITR!) intake valves for my H22a head, stating that something to do with the angle/design made them flow much better.

Does anyone have an info on these, or where I could get them? Thanks.

Why not? As far as I know it has already been done....You can also use ITR lost motion assemblies on H22a...

Can anyone confirm what was said about the UK specific intake valves? I didn't make much sense to me but he's built a lot of engines..

So is he on crack? Does anyone know about these? Hmm I have been told they are all the same...what the hell...

unless there valves in the uk are 35mm intake and 30exhaust they won't fit! stock b's are 33mm intake and 28mm exhaust!

 

Yeah I talked to him again...he meant Accord Type-R i.e. H22a

 

Supposedly, the JDM Prelude TypeS has a unique head design with different valve angles than the regular H22A. The Accord Type R and Accord EuroR may use this same head. The valves may be different, but they also may not be compatible with a regular H22A head...

Andrew - who is mostly just speculating...

 

That is correct, it's the valve angles

I have a thread a few down where I am looking for them. But so far the price seems hella expensive (like $500 US or Euros) for anll 16. I may just spring for the intake valves....

 

I'm not understanding... Do you want the just the ATR valves? Or do you want a whole ATR head?

The point I was trying to make initially is that the ATR valves may not be compatible with the "regular" H22A due to the difference in valve angle design in the head itself (if the ATR head is indeed similar to the JDM TypeS head)... Again, I don't know for sure. Just speculating...

Andrew - who likes to speculate about the worst case scenario

 

Ohhh.....I thought you meant the angle of the bottom of the valve for faster velocity or something...that's what I was referring too. I don't think there is an actually angle in the head issue....

 

what about those guys that had h22a4 heads and pu tin Type-S cams ang got funky wear or valve lash problems?? i thought that was from the valve angle in the type-S head vs. the angle of the USDM head...??

 

They are the same as in Prelude. Sent you some pix.

Pics? Post them! Post them!

Andrew

 

I will when I get home Mr. Pessimist!!

 

They are just screen shots from his Honda Electronic Parts catalogue...

Both part numbers say P13 for Prelude VTEC and ATR.....and are the same...

So maybe it's only Type-S and SiR-T valves.....maybe Euro-R

 

Are the last three digits of the P/N the same? That is where the difference would be if there was one

 

These were the numbers:

14711-P13-000 Valve IN
14721-P13-00 Valve EX

 

according to inlinefour there are mods which have to made so it will work properly but they also said Skunk2 is releasing an almost identical manifold around January which requires no mods.

 

? THis is about valves, not Intake Manifolds
