Plan A is always the most direct, least risky, most cost-effective, greatest chance for success.
Plan B is always more exciting and riskier by default.
1. It will fit and pump cool water.
2. It will reduce my boost charge temperature.
1. I will be able to drop back down to the 2" pulley (Gen3 well-ported top end with rockers and damn good exhaust system, not to mention bigger injectors finally) on pump gas. I ran a 2.3" last summer with no KR, and also tested my 2.2", with zero KR but a couple degrees less timing. 2" seems very possible with this setup, and that was my end goal.
2. I might POSSIBLY be able to run mid-grade with the 2", very likely with the 2.2". In that regard, the time, effort, and money invested could slowly pay itself off over time.
It WILL reduce the boost charge temperature. I WILL be able to run a smaller pulley. How much and how small won't be determined until summer temperatures arrive.
I should be making great progress through the weekend (no Katie) and have it ready to play with and install by Sunday night. It won't be installed until the replacement motor is ready to drop in at the same time.
Today'* early tasks are to replace my umpteenth dremel tool (need it for finish work), replace a couple worn bits, finish another LIM, then get back to the IC setup. After that, I have to rebuild the nosedrive, replace the needle bearings, then apply the heat dissipation magic coating to this SC as well as a Gen V.
Tall order for the weekend that may also allow me some time during compressor recovery (
) to adjust the new exhaust tips a bit and tweak a new little bit of magic I'm testing under the hood on the old motor right now.
