Turbo Confusion.......

[prelude9384]

Ok I want to boost my f22 in my prelude s...but I'm not that familar with turbos. I'm looking at the turbos on this site http://import-palace.com/ and I don't know which one too choose. Think I can run a turbo on my car without building up the engine for the turbo?(keep in my mind I want to keep it a daily driver and I'm not looking run alot of PSI's). So which one would I choose and can I run a turbo w/o buliding up the engine and keeping it as a daily driver???

Okay, i didn't go to that site, but i can tell you that if you have a relatively young engine you don't have to do any internal work if your gonna run say 5-7 psi daily. Most stage I turbo kits don't require any internal work. However, stage II and higher, you want to upgrade your pistons and rods. In some cases, you would want to upgrade your springs and retainers. You should definitely sleeve you cylinders if your running, i think, over 12psi. Just to let you know, i turbocharged my RSX with a stage I kit, which was a bolt on kit without any internal work, however, an Apexi S-AFC II is being used to keep the system optimized.

lets break it down: stage I, 10-12psi or less=no internal upgrades
stage II, 12-20psi=pistons,rods, and sleeves defintely
stage III, 20-30psi=pistons, rods, springs, retainers, sleeves, and a fmu.....stage IV, same thing as stage III, but u also want a engine managment system as well


If you engine has years on it, honestly, i don't know what you definitely should upgrade, but my best guess would be rods and pistons if you plan to run less than 12psi.

i dunno know about you but i wouldn't use a fmu at 20 psi and whats up with the stages. and yes you sould be able to run a turbo at low boost with stock internals, but your engine is almost 10 years old so ill at least do a compression and leak down test.

I agree with the compression and leak test, but why not use a fmu at 20psi???

It would definately be too much fuel pressure. I always wonder why people say I still want to use it as a daily driver. The thing that is nice about turbos is you can always change what you are boosting. Especially if you have a electronic boost controller. You wanna run 12 psi at the track, do it, you wanna run 7 psi for the street, it's just a couple pushes of a button away.

There is no best turbo for a specific car. It all depends on what you wanna do with it. How much hp you lookin for? How much lag are you willing to live with? Is it an auto or stick? What year is the engine? The earlier vtec engines are better for boosting cause they have a closed deck. Is the engine stock or built? Is the engine mildly built or totally built? Answer those questions and then you might be able to get an answer.

J/K I'm sure whatever one you pick is the best one. People just don't understand that there is no perfect, or best or whatever. You get one you use it, tune it, and voila!!!!!! Now it's the best one for your motor.

I would have to agree. Tuning the engine to optimize the performance with the turbocharger is best. The only thing I would add is that a smaller charger spoils faster, but is limited to the amount of power it will expel. You want to know how much boost you want and then get the correct size turbo. A bigger turbo will spoil not as fast as a smaller one, however if you have 2 of the same kind of car, one with a smaller turbo than the other and both vehicles are optimized, the one with the smaller turbine will kick out the power quicker and will give you a faster jump on the line, but down the road, the one with the bigger turbine will produce a higher output.
