turbos and accerseries

what are all of the things you need to make a turbo run? i know you need a bov, wastegate, intercooler, the pipings, the air filter, and the gaskets. is there anything else in a full turbo kit?

every situation is different, you don't NEED a blow off valve

the blow off valve isn't exactly needed, like windsonian said, aslong as you've got a wastegate and dump pipe you should be alright.

If you're running low enough boost to not use a BOV, you probably don't need an aftercooler as well (intercooler for the masses). See Honda City Turbo I, no BOV, no IC, ~11psi.

what about turbo's? you can buy any kind of turbo and put it in your car right? as long as you get the piping customized right? is there anything else to a turbo kit instead of the things that you listed?

Well Im not sure if this is what you ment by "piping" but you will need an exhaust manifold inorder to power the turbo. Also, depeding on how much boost you are going with, you are probably going to need bigger injectors along with a fuel managment system(like stated above) so that you dont get fuel cut. Also, a very helpful and also cheap peice for any turbo car is a Manual Boost Controller.

You'll also need all of the necessary gauges to monitor what is going on inside your newly built powerplant. A little knowledge about all of this stuff would be a good start. Find a turbo forum, don't ask questions, just read... A LOT.

At one point none of us knew a damn thing about this stuff. Then, (me anyway) we started acquiring every conceivable piece of literature we could get our hands on and ingesting the information.

This is a good play on words, but... knowledge is power.

Im with Bino on that one, I (along with the rest of the people here) have learned from lots of reading and some hands on activity. Dont just jump into something like this if you arent sure on how to do it. Just do your best to read all you can.

not necessarily, 8:1 is ideal but not necessary to slap a turbo on, only requirement is the tuning be top notch.

No, 8:1 is not ideal, it's just where a lot of guys put their C/R for ease of tuning. The new Cobalt SS runs a 9.5:1 C/R and then ~11psi boost on top of that. The new Mazda Speed MX-5 runs a turbo on top of 9.5:1 C/R, and the new Audi A4 2.0L runs a 11.4psi over the top of 10.5:1 C/R. People just usually set the C/R lower because it increases the margin for error.

I, personally, would like to increase the C/R on my turbo motor from 8.5:1 to 9:1, just to improve the off-boost response.

We ran 12:1 +18psi with Methanol on a boosted Ninja motor in college... that was sweet.

the only reason i suggested such a low compression compared to some of the other stock car's is because of what my mate has in his R32 GT-R, he's pushin' close on 450hp at the wheels and he need's a lower compression to be able to run much higher boost.

and to the way i've gotten my experience in motor vehicles and turbo's blah blah blah, yes quite a bit of it has been because of study and also from askin' question's like "what do you need to turbo a car", if you don't ask questions, you don't get answer's, doesn't matter if you look like an idiot, cause one day you'll be the one giving the answer's to the idiot's, lol.

i'd say my knowledge has come from a 50/50 hands on experience and studying experience, and YES knowledge IS power, i agree with you completely.

anyway, as was suggested earlier, bigger injectors would be needed for higher boost, i think that 800cc injectors are perfect to run about 18 - 22psi on, my mate's GT-R is runnin' daily on 18psi, he's got 800cc injectors with Nismo fuel rails and basically a complete Nismo package for the engine to keep it nice and cool while at high revs and pushin' itself to the limit.

it's nice when you've got enough money to swim in.... *drools*....
