help: my friends B16 is making JUNK for power

[Gilgamesh]

my just got his swap done. it was TUNED (s200) and dynod to 122hp and 112TQ

its a low miles jdm b16 block that came out of a friends jdm eg hatch
he bought a complete head off ebay.
other stuff:
255lph fuel pump
750cc injectors (all he had)
vitor x intake manifold
ebay header
LS tranny.


i think that the head might have automatic b16 cams which i heard were weak. also the intake manifold might be taking away velocity that a NA engine needs to be fed, idk


oh he dynod with an open header too. so were stumped... someone help out

[bigdare23]

750cc injectors


WTF!?!

[Gilgamesh]

haha i know i know, we has slowly doing a fully build gsr. sleeved block, crank,pistons,rods,head, but his single cam blew. and he needed a swap asap, so he traded all that stuff away for this POS b16

he still gets 25 mpg, and drives like a retard.

[Black4DrEK]

oook.. Who tuned it?

[Gilgamesh]

aurther @ trackmasters in huntsville, alabama

[mocha latte cupcake]

hmm...

compression good?

valve tick?

timing right?

93 octane?

i still think its soaking the cylinders though.

[bigdare23]

One the injectors are over over overkill!!!


Second stock b16 (which your homie basically has) makes around 125-135hp to the wheels. More than likely that intake manifold is robbing some of the power away also.


On a good note, your tq numbers are good. I have a homie that makes 88lbs of tq with his b16 LOL

[mocha latte cupcake]

thats stock HP B16. the manifold is too big, the injectors are too big, and the fact that its open header is all wrong. NA B16's need back pressure. so i doubt open header helped a "whole" lot but i could be wrong. but yeah i'm with dare on this.

Dare - leave jermaines little B series outta thing :lmfao:

[Gilgamesh]

it only ran open header on the dyno, it has 2.25 crush bent to a magnaflow turn down.


oh and when the car idles for 10 mins or so it gets loaded with fuel, it wont rev over like 4k until it clears out.

[Black4DrEK]

Dude the tune sucked because that shit is running WAY to RICH gettin way to much FUEL!!!

[The BUCKY]

my old b16 made 145hp 114tq with a header and intake and low compression

[bRiAnMcIvIcS]

255lph fuel pump= Should look into the walbro 190lph.
750cc injectors (all he had)= Way to big, 240cc are the stock size of a b series.
vitor x intake manifold= Look into skunk2, aebs, type r, or blox.
ebay header= Waste of money, get a header from mr. kidd.
LS tranny= Rediculous, get a b16 or gsr tranny.

Get a nice ss mandrel bent 2.5 inch catback system.

[Black4DrEK]

^^ Very well said!!

[allmotorX]

b16ftw in this case ftl!

I would agree, the victor x mani is OVERKILL for a stock b16, not to mention those 750cc injectors. Also, run a compression check.

[scttydb411]

255 pump is ok.
750cc inj are overkill, but can be tuned so not an issue.
intake manifold isn't nec, but probably not the issue either.
ebay header isn't the problem either for a stock b16.

stock b16 usually make 125-130whp and 100-110wtq. you're in the ballpark.

however, it sounds like there is an issue if it's loading up. the 750cc inj...are they saturated or peak and hold? if they are peak and hold and you're not running a resistorbox or if they are saturated and are running a resistorbox you have a problem there that is or has burnt out the injector drivers of the ecu.

when he tuned it, did he spend any time on idle afr, base timing, and part throttle driveability? what about cel...so you have any? what is the led inside the s200 box doing (color, solid, blinking, etc)?

do what this guy says hes a pro tuner.....srsly lol

the numbers seems right, but the over kill of the injectors/ vitor IM <---what for ?

[afwfjustin]

750cc on a non-boosted B series haha. If he wanted to sell them I'd consider them for my rb but I'd need to locate two more.

[boosted b]

injectors shouldn't be on that motor without boost

[Gilgamesh]

thanks for all the help,

the car runs great. no hesitation,bogs,pops,sputters, it drives like a normal engine, it burns oil in vtec.

the tune is good, it just doesn't make power.

ill get him to look at the lights on the ECU tomorrow.

[Tree]

lol wow you only had 122 at 112?? i make over 150.. on my b16

[Black4DrEK]

^ Dont you have the one with the B on the end......:ninja:

[big mac]

tell your buddy i will trade him 450cc blue tops for the 750cc's and a b16a intake mani for the victor x

[Gilgamesh]

hes no interested in letting go of anything.

he "says" it will be boosted. be he has no job and no motivation.

im having a hard time even getting him to diagnose his weak ass swap... his b16 making this power even makes me depressed! lol

oh he has 93 ftlbs not 112 sorry!

his single cam had around 112 torque and like 119hp and thats sad.

[scttydb411]

oh he has 93 ftlbs not 112 sorry!


now that does suck

[jdm eg99]

throw a nice turbo kit on there that should solve your problem. the intake is waaay to big for n/a you have all turbo upgrades 750cc injectors omg... just get a nice turbo kit n call it a day

[turbob20]

was it a dyno jet? or a dyno dynamics dyno? theres about a 15% difference between the two dynos. if thats the case what it was and he made 122hp on a dyno dynamics it would be around 140hp on a dyno jet. 122hp+15%= 140hp.

[Formally...]

LOL at everyone for saying it's the injectors fault for being too big. The injectors just do what they are told to do and if the tune is off then it won't run right. Yes the injectors are overkill but that is not the problem. I ran 650cc on my D16 NA before I went boost and with a GOOD tune the car ran like stock and made 106whp (250k mile D16A6)

I would def check the cams and also check what Scotty said. Ignition timing, cam timing, check compression, valve adjustment, strong spark in higher rpms, etc. Good luck.

[RedEj8]

Like turbo said, it really depends on what kind of dyno this was tested on too. Mustang dynos read lower than Dynojet dynos.

Hp and Tq are just numbers derived from each other using a formula.

[scttydb411]

no need to suggest the dyno guys...page one said he had it done at trackmasters. they have a dynojet.

[turbob20]

i wouldnt know that cause i just come to you,lol.

[HatchHero]

:???:?? ls tranny??

[dirk-diggler]

that intake manifold is killin g powre on all motor,its for boost

[speedminded]

What plug wires?


750cc on a non-boosted B series haha. If he wanted to sell them I'd consider them for my rb but I'd need to locate two more.You get that axle in yet?!

[Turbodude06]

WOW!!! Wrong trans, wrong manifold, wrong injectors, and no back pressure. Ur lucky it made that much hp......

-and this is an old thread i just noticed too:crazy:

[B20brid]

injectors may take on this. My old B16 141whp and 113tq
