Agree 100%, initially I was going to do a bolt on TVS only, stock ECU..but especially if you're doing the Vipec and 1000's, you'll be leaving a bunch on the table with an otherwise stock engine, keeping the boost where it's safe. You'll have a blower capable of quite a bit more boost than the stock engine can handle, so you're only getting a fraction of what the TVS can safely put out. I've come full circle on this--it makes more sense to me to build the engine first, then put the higher capacity forced induction on after, whatever that may be. Not saying you couldn't do it on a stock block, but I feel a whole lot better trying this with a stronger crank, pistons, etc. I'd rather have the engine overbuilt, the 1.8 can handle much more than the TVS can throw at it. To put it another way, if I had to pick one or the other, I'd do the 1.8 strroker before I'd do the TVS. Maybe I'm wrong, it's just my .02.
