What injectors

Campbell* · Post by Campbell* » January 9th, 2007, 9:51 pm

k, got the motor and a bunch of extra parts like spare intake and turbo manifolds, stock intercooler etc. I'v got almost everything I need to put in in the MX-3 other then a few small things. This B6T is out of a 89 323 GT sedan and is in great shape.

Im wondering what kind of injectors I should I be running or am I good on the stock ones. Im looking to make 160-200whp with this car

My set up consists of:
B6T out of a 89 323 GT
Stock turbo (unsure what it is)
DSM BOV
Stock 323 Down pipe with 2" exhaust all the way back
2.5" intercooler piping
24 x 8 x 3 FMIC
stock injectors
B6T ecu

What kin of power could I be putting down with this set up and how much boost should I run, this will alos be a daily driver so no pushing it to the limits haha

if ur getting the whole motor then just use the injectors that come with it. since ur using the b6t ecu i wouldnt see a reason to use anything else. as for how much boost you should run and what not, id just run it at whatever the stock setting is...i think its like around 8? i dunno been a while since i looked into that...but that should have u in ur desired hp range. just look up what the hp of a stock b6t online and that should give u a rough estimate..maybe a little more since ur going w/ a different intercooler set up.

it seems like u not very familar with turbo set ups. i suggest u go hit the books or net read up what u can. u don't know what size turbo the B6t comes with let alone the injecters size. i know, but if u want to know ur mx-3 read up the spec's from the avg. 323 GT. I own a 323 GTX myself. how will u ever reach ur goal of 160-200 whp if u know nothing about ur car or specs's. there's a whole lot more than swaping in a B6T into a MX-3 and calling it a day. its not as easy as it looks just ask some of the guys here who have done it. takes time effort and money.

I not trying to put u down in anyway it can be done what u want. i would be where iam at if i didn't know anything about my MX-3. i biuld that damn thing to what it is now. the only thing i didn't do was wire up the standalone and tune it. TRP did that.

do a serah on B6T swap's if u did u would know that u need to modifiy ur hood due to the B6T intake manifold. and other things as well.

them again do what u think is right. u have noe idea how beefie the B6T is.

the B6t came with 3 differt turbos did it not? The motor is not right here in front of me so I can't go see what turbo it came with. As for injectors I knew with what it came stock but my question was should I upgrade my injectors and to what or are the stock ones good. I have already bought the other intake manifold so that I don't have to run the hood scoop. Iv read what I need for the swap and Iv got everything, Im asking if I should upgrade my injectors and such to get the hp Im looking for

well if u knew them why post it as if u didn't.

u also should know that if u put bigger injecters depending on what size ur ecu might not control them at all and run super rich all the time. which would acually make u slower.

iam running 880's but them again i have something that can control them.

if u going to run with stock turbo then i run with the same injecters the B6T came with. with out a standalone or some piggyback u really can't tune a car. u can only really do a tune up.

the HP u want is not hard to get when u are boosted. just turn up the boost i belive any more than 16 psi and ur asking for trouble. ur stock injecter should hold and i doubt ur kep it there. most mazda guys who get boosted are afarid of the car. with what u want u'll probly have a 14 sec car. to slow for me.

i kno u got ur own plans in mind but here's my few cents, by the sounds of it ur looking at about the same kinda quickness/hp i was..but i put added the turbo to a b6de. i never got a chance to dyno the car or anything so i cant say for sure what my hp was but i was running a vj-11 turbo, an eclipse SMIC, stock BP injectors, not positive on the cc's but ithink it was around 200 maybe a lil more, a 12:1 vortec fmu, turbo xs bov, and my exhaust was 2.5 with a couple 2.25 straight from the downpipe w/ some cheap autozone muffler on it. the only times i had the car running right at the track was my first time ever there and w/ really bad reaction times i was running 10.0's and 10.1's so i kno i could have hit some high 9's...it wasnt a monster but i could take stock mustang gt's without too much problem....so unless ur wanting to be a lot faster than that, id just go with stock injectors and run whatever the stock boost setting is. i was running around 8-10lbs at the time...like i said...not a monster but fun as hell to drive..and with that b6t you wont have to worry about cracking pistons like me

hell yea and i cant wait for it

my friends dad is like a head tech at honda so he has all kinds of crazy tools in his garage to make the swapping relatively easy...i cant wait...and when i get it all in itll be the first time ig et to use that new garret fmic and the 2.25 piping

i might just have an accident when i take it out for the first time

10's-10.1's i hope u mean the 1/8 of the mile and not a 1/4. just wondering with ur setup no way that can be 1/4 mile. is states u keep cracking psitons reason why ur running lean thats what detantion does.

yea it was an 1/8th mile i ment to say that but i gues i forgot

sorry and im not to sure if it was detonation cuz the motor never gave any indications of it. i think my problem was air going into the motor was to hot...the reason i say that is cuz i never heard the motor detonate...and my a/f gauge always had me barely in the rich area..

were you intercooled? if you were where did you mount the intercooler?

facko · Post by **facko** » January 11th, 2007, 6:53 pm

yeah i was but it was that side mount..its kinda hard to explain where it was, it was in that gap on the driver side..like between the fender well and the front bumper sort of...like i said iono how to explain it but im like 90% positive that it just wasnt cooling the air enough. rookie mistake =/ kinda upset me tho cuz i had just got the new fmic and new pipes and everything. its cool tho i got new pistons and new rings that are gonna go into that motor im getting off you. so now that i got that nice intercooler and the profec b and all that jazz on there w/ the fresh pistons and rings as long as i dont over boost it should be a lotmore reliable

94blaze1.6 · Post by **94blaze1.6** » January 11th, 2007, 8:23 pm

no such thing as overboosting just not getting enough fuel

haha true true, thatd be easy to do w/ bp injectors tho
