what is the point of adjusting a bov softer or harder? if i am on the gas and make my full boost, lets say 15psi, will the wastegate open at 15psi and stay open if i stay on the gas that way i dont boost over 15psi? if the wastegate controls how much boost what is the point of a boost controller? can a wastegate be too big? thanks any help is appriciated

if its too soft it will leak boost, if its too hard it will not open and you will have compressors surge, you need to find the sweet spot.

yes, that is correct.

so you can adjust the boost level without taking out the wg and changing wg springs, also you can do boost by gear with the right boost controller/ems combo.

not really but the bigger ones cost A LOT more so get the proper size.

thanks man, with alot of the complete turbo kits you buy, does it just bolt on and safe to drive until you find someone to tune it? and if its just a simple setup and you want to stay under 10psi, a wastegate with a 10psi spring SHOULD keep you at 10psi if you dont have "boost creep"? a boost controller in this situation would allowe me to adjust boost under 10psi? when motors a turboharged from factory do they just run off a wastegate? if an external wastegate is on the outside of the exhaust manifold, where is an internal one located? what is the differnce between the two? do you have to get the ecu programmed to run FI?

if it comes with its own fuel management yes, if not then NO. most kits do NOT come with fuel management.

no, a boost controller can only raise boost above what the spring is rated at.

there will only be 1 wastegate, either external or internal, most factory cars have internal, most aftermarket kits are external. they both do the same thing, the main benefit of an external is it can flow more for higher boost applications.

you must have some sort of fuel management, a reprogrammed ecu setup for your turbo set up is one option. a stand alone ems is another option as well as a piggy back or even an FMU with stock ecu. in terms of whats best its gonna be like this:
standalone like aem ems&gt;reprogrammed stock ecu like hondata/neptune&gt;piggyback like apexi afc&gt;fmu

where do you go to get you ecu reprogrammed with hondata, crome, neptune? a local tuning shop? im in central PA. also what does trim mean? ive seen like .57, .50, but unsure what it means. and what would be a good fuel management set up for a 99 integra gsr, not really looking to go over 10psi at the moment?

Yes you go to a local tune shop they will take care of it there. I wouldent drive the car untill after they tune it. Some were on Ht there should be a tuner directory. Thisd will have all the shop around. But i believe Jeff evens at evens tunings is loacated in PA, And as i'm sure everyone here will agree with me he's probually one of the best around. As far as trim they are talking about the size of the turbo it is the relationship of the induce and exduce turbine wheel . As far as fuel management I would go with hondata and all your really need is a set of bigger injectors, that will depend on your HP goals. Whats are they ?

you need 2 things before i can answer this question, a hp goal and a budget, then i can tell you which EMS is best. however it would be a good idea to first see what shops are in your area and what they can tune, no point in getting an excellent EMS if nobody in your area can tune it. if evans is in your area discuss it with them, i always say get the EMS your tuner prefers.

as far as hp goals i was hoping for somewhere between 275 - 300. as far as managment goes im completely clueless on pricing aswell but if i spend somewhere between 500 - 1000 i would be epecting that. but like i said i have no idea on pricing. ive heard good stuff about evans tuning. wasnt aware they were in easton.(about 1 1/2 hours away, so thats not too far.)

As Blinx9900 said get check with a tuner first. As i said check the tuner directory to find a local tuner. As far as an Ems 500-1000 you can get ALOT. Crome is only i believe 150 dollars, hondata can range from 150 to 400 or 500 you can probually get AEM EMS for around 1000 maybe a little more. Check to see what they prefure I perfer hondata it seems to be easier for people to tune cheaper and gets the job done just as well if not better. But i wont be the one tuneing your car. As far as injectors for 275-300whp i would say around 450cc check with your tuner this is something they can help you with . If it's a 99 and the stock motor you shouldent have a resistor pack so you'll need high impedence injecotors.

if that range is acceptable for you then i would suggest something like hondata S300, neptune RTP or my personal fav is AEM EMS, you should be able to track down a used one for about $750, hondatat S300 will be more cost effective option and should be more than enough for your power goal though
