Will the valve train for those years work with a 97 ej22? I'm going with some delta cams and would like to upgrade the springs as well. I think that delta can supply them though. But thanks for the idea with the ej22t.

 

it would....but it would be a downgrade......Hydraulic w/solid follower.

 

Your 97 valvetrain is solid w/roller follower.

 

All EJ22 springs are the same

Paeco suggests that I use aluminum retainers with the stiffer springs to handle higher revs, but also said that if Im going as high as 7500 then I need titanium retainers. At $25 per retainer I cant justify dropping that much on retainers. What do you all think about this this? Ill probably just stick to the aluminum as they are $8 per retainer.

Are you using 2.2 heads and trying to get 7500 rpm?

I'm not sure the 2.2 heads flow well enough to achieve that.

Yes Im using 2.2 heads w/ the Delta 200's and the hi-rpm spring set from Paeco. Im also going to do some light porting and matching on the exhaust side. Ill be using Grimmspeed phenolics also. I think the aluminum retainers will probably be fine. Even if I can rev to 7500 its not like I will do it often. Plus im going off what Delta told me the cam is good up to. More just want to match the valve train with the cams. Im also using a 2.5 ecu for a higher rev limiter.
