1.9s aren't going to completely kill your setup or anything.
They just aren't the best option for a n/a engine.

You'll want to do the springs if you move the shift points past 6k with 1.9s. And that'* what you'll have to do to get the most out of that ratio..

You'll want to do springs even if you do not go past 6k rpm'*. I didn't have an air compressor, so I didn't install the springs and have experienced some valve float.

I think I will end up going with the ER rockers for the time being. When I go with the turbo, I can always sell the ERs. Do the ERs require springs or pushrods???

The person who developed the ER rockers, Wizbang, said aftermarket springs are not needed unless you are shifting significantly past stock shift points.
He also stated that if you do experience valve float, 85-90lb springs on the intake valves ONLY will solve this. (The intake valve weighs more)

I believe at least two people on this forum (tj'sblackbonnie and firebuick) have run ERs in conjunction with stock springs without issue.

Mike, is right. I had ER rockers on stock springs and Don (firebuick) also does.


They worked fine (and my car being a 95 shifts higher then others. I was seeing shifts as high as 5950 with no issues)



PS--- I loved my ER rockers, and would reccommend them to any L36 looking into a cheap and effective mod.

Im hoping with my head and intake mods, that the ER rockers will be that little extra that I am looking for. Would hotter coils make any difference at this point?
