Ok, the nomenclature you typed makes more sense and makes it easier to discern between the two.I've seen the Evo 3 described that way in a couple other places over the years and I think it just stuck in my mind and I kept calling it that, even though it didn't seem right or necessary.One of...

Ok, I’ll save my money then.Thank you both for the information and the help.

Yeah I’ve had that thread bookmarked and I referenced it in the past when I was researching how to determine what turbo is what based on the numbers stamped on the compressor cover. That’s how I knew which model 16G each of these turbos was. “42” on the Big 16G, “47” on the Evo 3 16G, like you...

I totally agree, I always opt for real vs. fake.Both the turbos I'm referring to in my original post are Genuine MHI, I'm wondering if there is any theoretical advantage of any sort to running the regular Big 16G as opposed to the Evo 3 16G? I already own the Evo 3, so if not, I would pass on...

I am looking at purchasing a used, good condition Genuine MHI Big 16G (Non Evo 3). However, I'm not sure I need it as I already own, but have not yet installed, a genuine MHI Evo 3 Big 16G and also an MHI small 16G. When I do make the upgrade from the 14B I'm currently running, it will be along...

Thank you for the reply, there is a lot of good info contained within. It definitely gave me some knowledge/insight into the ins and outs of our 4G63 heads.

Thanks for the replies. Coming from you guys, that’s enough reassurance for me to feel fine about reusing them.I’m not sure where I originally read that they shouldn’t be reused, I think it was in the product description for aftermarket 4G63 keepers, so that should obviously be taken with a...

I pulled the head on my Spyder to upgrade cams, springs, valve seals, lifters, etc.It looks like the valves and valve seats are in good shape so I’m going to just clean them both up and reuse the valves. Originally I was thinking about putting in NEW valves while doing all this work but am...

Thank you for the reply, as always.I was thinking the aluminum head vs. steel cam would work in my favor, so thank you for that reassurance.I was hesitant to hit it with any abrasive for fear of making it worse, but if I do, I'll go with the 1000 grit like you suggested.Thank you again

Upon removing my valve seals for replacement it appears I nicked the edge of a cam cap. It is really hard to get a good picture of what I am referring to, but I tried. The nick isn’t on the contact surface of the cam cap, but rather the “edge” that forms a 90-degree angle between the surface the...

It looks like Rock Auto has an option for the passenger side:https://www.rockauto.com/en/moreinfo.php?pk=700143&cc=1205806&pt=1380&jsn=373

Ok, that’s good news, thank you guys for the input.

I just pulled the head on the 1996 7-Bolt that I took out of my Spyder GST. Upon doing so, I found the exhaust valves had an uneven white crusty substance on their faces as well as a white substance on the valve stems, viewable through the exhaust ports when the exhaust manifold is taken off...
