Even on a ported head with a big turbo for topend? Hmm.... is there a discussion that was had - (Yes I understand overlap)
If it was in combination with a modern day turbo setup it would be ok. Most modern turbo setup have a bit of overlap because back pressure has been greatly reduced along with increased turbo efficiency. With an 80's technology turbo, it is not a good combination and will cause reverberation back into the combustion chamber.
As far as the specs go, I'm waiting on my buddy to send me his 'new' old stock mechanical lifter 20vt cam meant for a URq. I'm going to have it reground to a 234/228 with .460" lift.
"THE CAM" is currently under repair at Delta in Tacoma, WA atm. They were not able to regrind it to a different spec. They told me if they welded onto it, the welds would break and come apart over time. They instructed me to send them a mechanical cam for the specs I want
I have however run into a problem with the car. It pulls very well with the MC2 cam up until about 4800 RPM where it decides to start misfiring and having a HUGE lack of power while under boost and a load. Up until that point it has NO problems with full boost. Really weird. I'm wondering if it's my sparkplugs or if it's a fueling issue.
