Custom or Kit Turbos?

[KaMaKaZiPyRo]

Wich one would be a better setup for a daily driver, which one would be able to have more power and which one would be able to hold longer?

[DeleriousZ]

custom will always make more power and be cheaper than a set kit... how reliable it is depends on how well you put it together and the quality of the components you use, if you're lazy and don't know much about turbo's and stuff, get a kit and get it professionally installed

[KaMaKaZiPyRo]

Alrite, but I heard sumthing about only one of them, custom or kit, would be able to use the boost contoller or be able to be increased or tuned or w/e i forgot maybe sumone knows what im talkin about.

you can use a boost controller with custom OR kit

hehe...i'd let a pro take it from here

[KaMaKaZiPyRo]

so what parts would I use for a ood custom kit that i would be able to keep a/c, and steel have a decent amount of power and be able to be at like 10 psi, with a b18c1 with upgraded internals?

The FMU's that come with some kits are usually set up for 6-7psi of boost (the Greddy for sure) so if you're planning on boosting more than that you'll need to get a better engine management unit (ie Hondata.) But it really depends on what motor setup you have, whether you build the block to handle more boost or not, if you don't build the block then I'd say jsut use the FMU that comes with it until you do build (if you go the kit way). But also with the kit you might be stuck with how much the turbo is efficient, how many psi it will boost up to, and how much the wastegate will go to before blowing off. And the kit manifolds would only be compatible with a couple other turbos if you decide to upgrade the turbo down the road. With a custom kit you'll be able to get the right turbo for the power you want but with the kit you'd be limited to the turbo or turbo family the manifold you get comes with/works with. But you'll want to get it tuned no matter what you go with; more reliability and more power out of the kit.

Way to break it down CivicSpoon

Oops...was writing while the other post were up I guess. There are mainfolds around that would let you keep the AC. Think that www.fullrace.com or whatever has some on their site that would let you keep it. But if you're wanting to go 10 psi I'd say go custom and get Hondata for an EMS (AEM EMS is way more expensive and I know a few people with it and they have nothing but problems.) And go with at least a T3/T4 turbo for good spool and boost, anything smaller wouldn't boost fully thru your rpms, i mean it'd max out too soon.

WASTEGATE regulates psi
uberdata or turboedit will work fine

[KaMaKaZiPyRo]

anyone know of any kits that come with, t3/t4 or do u have to do that one your own? and is that about the highest youve ever seen a kits fmu get too was loike 6-7 psi, and coudlnt yu juss buy a hondata and use that with the or would it not work

[Beyond Imagination]

turbonetics
revhard
drag
and many more kits use t3/t4 hybrid

fuel management has nothing to do with boost pressure. hondata is a good engine managment unit. without the boost option on hondata it's pretty much a basic ecu with tuning abilities. if you don't need a stand alone management unit then go uberdata or turboedit.

[CivicSpoon]

DRAG turbo kits use T3/T4 turbos, don't know of any other from personal knowledge. I'm sure there are some kits that have the fmu for more than 6-7psi, but again I have no personal knowledge. On turbo-kits.com they have the FMAX listed as 8psi (i'm sure the kit itself will do more than that maybe that's the FMU max?) and the rev hard one says 15+ so maybe try to find more info on those. Oh yeah you could definently use hondata or what have you with a full kit.

[CivicSpoon]

lol... yeah what Beyond said

WASTEGATE:
A wastegate is used to control boost levels by allowing exhaust gasses to bypass the turbo, thereby decreasing the volume of exhaust available to spin the turbo's turbine which will limit the amount of boost created by the compressor. The wastegate has an internal spring and diaphragm which boost pushes on, these springs are rated for different psi levels.
