Almost put it in two pieces. Still surprised this didn't come apart, all of the drivers side main cap stud nuts (except the rear one) were loose when I pulled the pan off. All of the main caps (except the rear one) are cracked where the block split. It looks like the rotating assembly survived so I will at least be able to salvage/sell the rods and pistons.In to see block in two separate pieces
I did talk to a couple guys with an Si and vortech themselves, and they all confirmed 600 rwhp should be no problem. It is approaching its limit at that point, but two of the guys were over 650 with a setup comparable to what I'm looking to do. Vortech rates the Si HD v1 to 775 HP. Mine isn't the HD gearbox version as its from the 90s, but they still rate the non-HD Si to around 700 hp and 52000 rpm. The future plan will be to upgrade or go turbo.Can an Si be stretched to 600rwhp?
I always thought you needed to goto a T.
Two project mustangs.
I don't envy you.
