Hey guys,

I have been driving my 1uz swapped 1990 cressida for almost a month now. The motor runs great but I have noticed that the entire exhaust from the manifold to the muffler gets EXTREMELY hot during hard WOT runs. I would expect the manifolds to be very hot but even the muffler is blistering hot. It has dawned on me that I did not replace the OEM fuel pump with an upgraded one. I am wondering if the engine is leaning out at WOT with the oem pump (for the 7mge). No part of the exhaust is glowing hot but I can "smell, see and feel" the heat after a long hard pull.

Any comments?

Another thing. I deleted some of the vacuum lines. I am running the fuel pressure regulator vacuum signal straight from the small port in the front of the intake pleneum just above the iacv. I measured the fuel pressure at idle to be around 36 psi.
