Thicker head gasket for forced induction

I'm completing my Turbo project and have yet to find where I can get my hands on a thicker head gasket for the Fit. Can someone please tell me if they know anyone who offers something like this?

I have driven turbo cars with low compression ratios and found them to suffer low RPM lag.... Wouldn't it be better to install a self tuning device like the AEM A/F/I to set the mixture and timing than installing a thicker head gasket that will lower the compression ratio?.... I can see where a thicker gasket would be beneficial if you were pumping some really big boost and planning on keeping the revs up all of the time in a purpose built racing engine that wouldn't see much street use..... If that is the case you may have to make (or have one made) of solid copper, using a stock gasket as a template.

Do you have any experience with Greddy Electronics. Heard that the E-manage is the most commonly used because it's the least expensive. I have a set of CP Pistons for the compression reduction...think that will do fine for now...needed for additional boost.
I ran a 16G on my fit last week with a modest log-style manifold...didn't run bad at all. I think I like it better than a GT25 or GT27. Spools at around 2,700 RPM's or so and developes more readily available power. Don't know anyone else who runs with that...mostly the GT25

Explosivepotato Is The Man when it comes to tuning turbo charged Fits and has experience with both and has gone from Greddy to AEM after being turned on to it by leonine..... They both have provided a lot of info on this forum about tuning..... I am still learning and drive a Kraft Werks equipped Fit with a puny 5 Lb. boost, for the time being. I am only limitedly familiar with Garrett turbo chargers.

I plan to go with the AEM FIC after reading about the Greddy failing to work properly on the L15A engine during partial throttle.

-And for what it's worth I was going to run a T25 but couldn't find one cheap enough so I settled for a 14b from a Galant VR4.

how much power are you planning to put down?

looking for around 200+

I have my Emanage ultimate for sale if you are still looking for one.
