Thanks! I hope to have it finished soon. I'm hoping to have it with working a/c too.
Max 8k rpm but I'll most likely keep it under 7500, 99% of the time. This is what the engineer said about the springs, "With this camshaft i would say that the rpm range will be 3500-4000 rpm to 7500-8000 rpm. With the springs the limit is 8000 rpm we also have gold springs pac-s10015 same specs but for higher rpms so 8000rpm and up."
Not sure about the weight, I think 30grams. They're Lexus part #13711-38050 about $14 each. Catcams said I didn't need titanium retainers so all the OEM 2gr stuff works, IE keepers, seats, retainers, etc.
I went with the cheapest online vendor, oemvehicleparts.com for the lexus parts and mcgeorge toyota for the OEM toyota stuff. I buy only a few things here and there from MWR.
I'm looking for denso 550cc injectors for the 2gr at the moment.
