I have a set of Y irons and a set of R5 irons....

drawbacks of mixing this badboys?

Any input welcome

PS: I cant edit the title...

ironGs...

LOL

 

R5 are a little heavier. That is all.

 

Somehow, I knew you were going to be the one with an answer

are both nitrided?

 

You tell me.

 

hehe

how can I tell?

 

All Ys are nitrided. Some R5s are. Examine the surface of your Y and compare to your R5 plates.

 

I knew about my Y irons, but Im not sure about the R5

the Y has a more "mirror like" finish

the R5 came out a 1980 car

Im still cleaning them and I think I found some pitting.

If they are ok, I will port them into a half bridge

 

I thought about doing a half bridge, then was told they're crap, so I'm thinking about doing a peripheral port now.

 

Im building a street port engine with the Y plates.

the R5 irons will go 1/2 brige, Megasquirt, cbr600rr ITBs

I´ll let you know if I ever finish it

 

Boost and/or EFI can help with a half bridge.

 

I already got the ITBs and the Megasquirt.

Will post pics if you are interested

 

i would say pics are a must

 

^^ Agreed.

 

so would i

 

That's why I will only run the Weber dual DCD carb from Rotary Engineering on a secondary 1/2 bp. Drives like an sp until the secondaries open up. When I had the 2 barrel Mikuni on it, I often had to drive in 4th gear at highway speeds, 60-65. Now I can cruise through town at 1500 rpm, instead of 3k with the 2 barrel.
