Awesome thanks.. I'm in Florida and figured 93 on a decent/safe tune would be about that.

Here is another stage 3 turbo option that some might recognise/be interested in.

https://store.kinugawaturbosystems.c...39335320715450

Apparently a Zage product that various companies buy from and sell on. Looks very similar to the Vargas n55 GC (even down to the description) however i believe they are going down a different route now due to poor results. It also looks similar to a UK companies offering.

I suspect we will see multiple stage 3 stock location turbo options over the next year or so.

Is shuenk same as franketurbo? Their OE + stage 1 appeals to me most as don't want big power but small turbine upgrade would be nice maybe...

God damn this Rabbit hole.

Yes they're working together. The n55+ will be branded shuenk, the bigger n55+ will be branded franken turbo.

It will be interesting to see how the supercore does on an EWG turbo, IMO I doubt it will add much. Its just over 1mm larger on the compressor side while using the oem turbine wheel etc, which is part of the restriction on the oem turbo.

I feel the N55+ might be the best option in terms of spool vs power. New larger twin scroll manifold, 53.5mm comp wheel, 52mm turbine wheel removing all the oem restrictions. No core charge and not much more than a stage 1 upgrade.

Yeah the supercore won't offer that much on an EWG car so that is why I heard they might not make an EWG version.

Yes I too agree the n55+ might be the best bang for the buck for track guys, eliminates the restrictive factory turbo fold, and upgrades the exhaust side vs. stage 1 turbos. This should really lower back pressure and egts allowing for more track usage.

So, how much longer do we have to wait?
