I might be able to buy a set of 2nd hand ATR cams(same as Prelude Type-S) at a good price. Will they work ok if I fit them to my Prelude with new springs and retainers but use the stock P13 ECU?

I know I really need the type-s pistons too for the higher comp. ratio.

Was just wondering?

 

they should

 

A friend has Euro-R cams in a 2000 lude with a stock ecu...no problems

 

What kind of gains will the type s cams make in a stock jdm h22a if you just dropped them in with no other upgrades?

 

lol, prolly won't be much maybe 5 hp the most, because u already got an JDM, u might get more hp if ur motor is a usd...

 

Mine is a H22A2 (UK version) with the 10:1 compression. I have the type-s intake and a sports filter fitted, and a Janspeed 54mm cat-back zorst.

If I buy the cams, and later get a set of new type-s pistons will I need the type-s rods also, or will the stock rods be ok?

 

is the uk head the same as a usdm head? cuz i heard that the type s cams are not made to work in usdm heads cuz the attack of the cam will wear excessively on the rocker arms.
