which one would you prefer for my 94 dx 5-speed 7afe?? which one would be more reliable as to providing power? does my car come stock handling turbo well? how about super charge? which one provides more power? which one would last longer on my 150,000 mileage car? which one would provide less wear? any other tips would be appreciated, thanks
supercharge is less maintainece. turbocharger has the potential for the most gians if u put in enough. but the s/c will do the job w/o having to wait 5 mins before turning off car to wait for t/c to cool down

A water and oil cooled turbo running low boost doesn't need a cool down time. But turbocharging a car is a lot morre difficult than supoercharging it. If they make a s/c kit for your car, it may seem more expensive at first glance(one turbo=$500, or one s/c=$2,500) but the s/c will come with everything need to run it(a belt and a pulley, woohoo) and all it does is replace your intake manifold. Turbos require all sorts of extra piping, new exhaust manifold, downpipe, and will end up costing you the same as a s/c anyways. Turbos are more flexible, but you're not gettin much more power out of that engine before you blow it.
The 7A is not a reliable enough engine to run either, imo. Being a stroked version of the 4A, the bottom end is far too weak. You would need the higher displacement of air that a twin-manifold twin-turbo would give you without putting too much pressure on the bottom end.
Unfortunately, the FE's dont put out anywhere near enough power to run a twin-manifold setup, and the piping in the already restricted engine bay is rediculous(sp), as you would need to connect one up to pistons 1&3 and the other to 2&4 to get a constant enough output. imo - not feasable.

thanks for replying, what if in the future i'd like to increase my hp and torque, would you recommend turbo charging if i'm only providing about 5 psi to my 7afe? is that safe? one of my friends have a 4afe turbo and he is running about 5 psi also, would my engine be able to handle 5 psi and still be safe as to not blowing up my engine? if at that low psi, would it more reliable than super charging my engine? (turbo 5psi vs. s/c) ??
i'd rather not do an engine swap, too much $$$ for shop to do and swaps are not easy to do, as i would have to do it myself.
answers to my questions would be much appreciated, thanks, and any other comments would be great as i am still stuck to whether s/c or t/c or swap, what would YOU do if you were in my position with a 94 dx 5-speed 7afe?
if u really wanna turbo... save the 7A-FE bottom end get a 20v head w/ 4AGZE piston and rods and then do a turbo... or just get a 3SGTE swap...
decent idea, but with all the money you'll spend/waste just to ge hp you might as well, buy a 4age run low boost and with the left over money buy a prostitute.
