I think you can machine the honda dizzy and yota dizzy to work. Great success has been had with megasquirt tho, im using ford edis and its been solid for years. I don't know if i would run 400whp on it tho. I understand that both blocks will take the abuse with proper tuning but I havent heard of anyone doing more than 1 pull on a stock piston'd 4age. The gze pistons are stout, and the silvertop bottom end is identical to the gze/redtop ect. But in no way should anyone be led to believe that GZE pistons will take 400hp worth of abuse daily. They might last a few dyno pulls but that is it. They are super strong for what they cost, ceramic coated and will fit when you flycut them but they wont take those kind of cylinder pressures. All it would take is a bad mix of heat, bad tank of gas, maybe an incline before they ---- the bed. Anythign is possible but caman ... Someone did some metallurgy tests on the GZE pistons and they turned out to not be forged iirc, something with the grain of the metal. I can't remember. Most people shooting for near 300 will change the pistons at least, and some leave the rods as well.

Soon to upgrade to my 4 bar map sensor so that I can tune my N/A points and be drivable when I add the turbo. Also I was thinking with the VGT turbo, running the vanes wide open at cruise, then let them close up about 30% throttle and up, it'll lag a little, but I think drivability will be much better, plus I'm not advertising too much cruisin down the highway when I dont feel like running someone.

I am not the least bit interested in what "people normally do to achieve X numbers" I want to know what broke on theirs and when.

No offense OP, but I'd consider a form of engine management that didnt totally fail from the factory, and wasnt designed with spinning triangles in mind.

Ill bet money ive met face-to-face with the majority of high-end MR2 savaints in this hemisphere. They didnt get to where they are because they listened to people who say 'it cant be done'

TTC, im not trying to start an arguement here, but the quote "that cant be done" is the motivating force in my life. Sorry if I come off as an *** on the interwebz. Im really a nice guy in person I promise.

Re: 4A-GTE Configuration Questions
Hey man, no offense takin here. If you can do it go for it I would love to see it, a few Aus guys have made ridiculous power without even cracking a used block apart. Even my car makes good power with used up old bearings, no machining, used pistons from a blown motor and a tijuana tune up. Im not going to argue tuning with a few guys that have much more experience than I. What I can bring to the table is my experience with these engines for the last 5 years.
