do they require fuel mods? management? cooling mods? basically if i were to get them....what else would be necessary?

 

if you have to ask, you probably shouldn't get them

upgraded fuel system, intercooler, radiator wouldn't hurt, and you need a way to control the fuel and timing... it'll be $2-3k on top of the cost of the turbos easy

 

ur probably right....about not knowing :P but what other alternative route can i go? i need a new motor and turbo's soon....so yea...i'm kinda stuck :P

 

well if you're not doing anything for fuel control, keep it stock.

 

I would get at least 4x720cc injectors, Walbro 255 fuel pump (rewired), and SAFC to tune it, and a FMIC. That would be the minimum required to run it at 15 psi, IMO.

 

fd secondaries are 850cc stock

and safc's are junk for 3rd gens.

 

You can just install them and run them at stock boost levels without needing any additional fuel management or anything else.

But if you're going to do that, I would just go with some brand new 99-spec twins -- they're only $2600 right now and they are brand new....

 

^ i hope that's from experience. i thought they were hybrids--which would make them blow more air at the same boost level. tell me how you came to that conclusion.

 

Simple. The stock ecu can easily handle all of the bolt-ons at 10 psi and still be on the quite rich side of things. The BNR Stage 3s do flow more air than the stockers but not enough more to put you into the danger zone, at least not at the basic modding level. If he is already fairly modded and wants to install these, he should have an aftermarket ecu and fuel system already anyway.

 

hybrid turbos are a little past the basic level of upgrades, don't you think?

 

I'm not sure how well its going to run w/ bnr stage 3 and stock ecu.. Most stage 3s are non sequential.. So, upgraded ECU is recommended.. W/ older bnr stage 3 you could pretty much bolt it on to stock turbo manifold to go seq.. but not sure about the new one..

 

Wong needs to upgrade ECU before upgrading his turbo unit or he'll ruin his new engine and turbos. Don't get caught in the "not enough money to do it right, but enough money to do it twice" trap.....

 

I'm an idiot...didn't realize he had an FD. FC's are always on my mind.

 

Bolt them up then get on the dyno to check the a/f ratio. If your in good shape then go with it....if your a little lean then dont get into the boost and swap to a PFC.

You can run them seq or non seq...either way is fine its just most people when running high boost prefer non seq. At 10psi and stock ecu or pfc I'd just keep it seq

 

i would probably want to keep the sequential setup, is there a problem to keep it at 10 psi? or would it not be worth it to even get the stage 3's if i'm going to do that?

don't they offer stage 1's anymore?? LoL

 

if you haven't done an intercooler, exhaust and engine management, you'll never realise their potential. exhaust and an intercooler will give you the most bang for the buck IMO.

 

so basically i shouldn't be getting the stage 3's if i don't plan on doing those mods? (not saying that i won't, but just in case)

so i would probably be better off getting like 99'specs or something?

 

Go with BNR stage 3.. I ridden in the new stage 3 and I'm getting an older set in next couple of weeks.. the new set makes some power!!

Just do it in steps.. make sure you got everything..

 

i love my bnr's....just need to get it tuned then weeeeeee! :-)

 

you can't make power unless you can control it!!!!

 

Are your current turbos blown? That was my assumption from the beginning but maybe it was a poor one. If your current turbos are fine, then there is ZERO reason to upgrade to Stage 3s without serious mods to take advantage of the higher flow capabilities. As for the 99-specs, really the same situation applies. There is no reason to "upgrade" if your current turbos are fine.

 

well i just figure since i'm pulling the motor out...i might as well get new turbos, cuz the ones on there now are the originals w/ 100k miles sooooooo yea.....

 

just pick up a used set for a couple hundred bucks. i'd offer mine, but i decided to do a twin turbo fc

 

I wouldnt even mess with the 99's they will make the same or less power than your 93-95's and they cost the same as the BNR's. The 99's also have the same junk shafts and turbine design as the 93-95. They are the same turbos...there is a special edition of 99's that spool a tad faster but they have smaller compressorwheels. All of the new 99's cost more than the BNR's. I would either keep your 93-95's or get the BNR's....one or the other, I wouldnt mess with the 99's. If your engine has ever been blown (causes the turbos to go bad) or your turbos are just smoking and going bad then I'd get the BNR's and just make a couple passes on the dyno to make sure the a/f ratio is safe.

EDIT - I just saw where you said your pulling the engine out. If you busted a apex seal then your turbos are shot and you need to replace them....I'd just call Bryan at BNR.

^not always. i've seen a few fd's blow seals without damaging the turbines.
