So basically you'll lose some significant power/performance.

These tend to work okay on turbo models because the boosted air will pressurize the intake manifold so air will be readily available for all cylinders.

Stick with the GE manifold. It's design is one of the best possible ways to disperse air in a fuel injected inline engine. Besides, the heat transfer from traveling over the exhaust manifold/headers and engine is minuscule.
ok thank you for the info! thats the one of the answers i was looking for. also how does ACIS work? i would like to under stand that better so if you have a link that would be sweet!!! as it stand right now making my 87 into my project car would be a bad idea. so ill take the two GE's i have make one fix what parts of the body are needed and gut the 86 junk it and make the 87 my DD and wait till i get the 90 supra i want for the project car.
