Great insight there Matt.

Discovered this back in early 2000, then I was running stock 4efte with t3/4 s-trim, 63ar turbine on 4efe cast manifold chopped to add t3 flange, making 325whp/25psi. Stock ECU with Tech Toms e-prom & e-manage blue. Stock head with 4age valve springs, stock head gasket at 60lbft . The key to keep things together is in total timing. Tune for max HP and then take a couple deg off. I also did a stock 5efhe engine and made 364hp with the above. 4e is the way to make big power. Now here in Jamaica we have 600+ and looking to do 800+

My COMPLETELY STOCK 4efe is on 10psi trough an eBay GT3582 with a .63 rear housing. I made my own log style manifold (gross I know). the logs 1 1/4” diameter is less than a T3 flange, so it required a built of building with the mig to make it fit. Seeking as the logs open into an open chamber under the t3 flange, I’d imagine it breathes alright. At roll racing I ran it with a 50 shot of nitrous and 12 psi boost with 6 degrees more timing than on street duties. It’s thrashed on the daily to work and back and I’ve had no issues on 98 octane fuel. Built 5e is in the works, so we should see some impressive power out of the little thing.

Exhaust back pressure is a big killer. Not many people check it or egt. High exhaust back pressure causes high egt, which causes everything to get much hotter, spark plugs, valves and even an mls gasket if slightly too small, the thin metal can become a hot spot. Measuring exhaust back pressure is cheap and simple, should always be done.
