Which one??????

[soundagent 51]

Looking for a new car, but cant decide which one to get, it is between a 92-96 honda prelude, or a 91-98 nissan 200sx se-r, i am planning to turbocharge and most likely supercharge the car, and am looking for the one with the most power without engine swap, i am leaning toward the prelude, but any suggestions??

turbocharge and supercharge? why both? you realize thats largely pointless, right?

Not all '92-'96 preludes are the same, some come with very crappy engines and some have fairly good ones. If you're going to boost, I would get a Prelude Si with the H23

i heard that turbocharging and supercharging would give it more power, but i guess i learn that that is wrong, also, i did some reasearch and the se-r does 140 stock and the si does 160 stock, but can any of you guess help figure out which one will end up with the most power once the turbo and everything is in?

whats the displacement of the motors? what kind of turbo? what kind of supercharger? How much boost will you be running? Will you be running an intercooler? Do you even have the money to do this? All these things factor in how much hp the car will make?

well some 200sx's came with a sr20de which means you can swap in the sr20det or just get some machine work done to the sr20de block and get the sr20de head and all the stuff that goes with turbocharging. you could probably end up with the most power out of this platform as opposed to the honda motor. also look at the vehicle weights, its not all about HP. A lighter car will handle better, accelerate better, and break better.

oh yeah and the sr20 was pretty much designed for turbocharging (but there are some internal differences between the sr20de and the sr20det but i dont know what they are)

i dont know what displacement, probably a turbonetics turbo kit, yes, i will be running a intercooler, and how much would it be for a engine swap to a sr20det or just to machine a sr20de? i still have alot of time to think about it.

a turbocharger is a supercharger. Its just exhaust driven. They do the same thing as each other, force air into the engine. Centrifugal superchargers and turbochargers are more efficient than roots type chargers. This means less intake temperature rise. Turbochargers are believed to be even more efficient because they theoretically do not rob power from the crankshaft. Some exhaust restriction is created though. I would recomment swapping the SR20DET. This way the engine is already turbocharged so you don't have to worry about internals, fuel system(for a little while), idle control stuff, timing maps, fuel maps, ect. If you turbocharge the existing engine, you will run into problems with the fuel and timing maps. Good luck.

so get the 200sx, swap the engines,and slap a turbo in there, ok thx.

[nissanfanatic]

If you swap in the SR20DET, it already has a turbocharger.
SR=engine series
20=2.0l displacement
D=twin cam
E=electronic fuel injection
T=turbocharged.

wouldnt a after market turbo on a sr20de be faster than a a sr20det?

[drdisque]

nope, SR20DE has cast internals = low boost

[Reed]

might be faster till you detonate a piston or put one through the head. also the sr20det has oil squirters for the bottoms of the pistons whereas the sr20de does not, that is the machining that would need to be done (also maybe some clearancing for beefier rods i dont know)

[soundagent 51]

nice, how much do you think it would be to get the engine swap?

[nissanfanatic]

It would probably do okay for low boost. The KA24E and KA24DE have cast pistons and have held 16psi. That was with AEM EMS but a lot of guys run 12psi everyday on the stock bottom end. IF you can tune it well, it should hold 5-7psi no problem. Correct AFs and timing are the most important factors in whether or not your engine is going to last under boost. Judging from the way you sound, you should probably just get the engine swap.
