Would you have any ideas on what can be the reason for the flat horsepower.
That dyno looks real good I just started last night my 93 acura integra B18A stock engine on the outside but 85mm on the inside...
Im going to the dyno this weekend and hopefully bring back better numbers....

Definatly fix your A/F, then check your timing (datalog if possable).
We'll work from there.

You aren't boosting the teg are you? So sad, I <3 boost. Oh well, my rex isn't boosted either. Sleepers are good though.

who would expect that to have ~180whp

Im not boosting the teg im going to NOS feed 150hp progressive system
but im not VTEC. I got cams and everything with a very well ported cylinder head...85mm 10.5:1 pistons,connecting rods, intake manifold, throttle body etc......

im going to rev it to about 9,000rpm just to be safe but I know it should be very good at least 12 no sweat...

But im LOYAL to DSM so HONDA is just like a daily driver...and for the real performance is my Talon....

im sorry but those numbers seem low to me. Expecially for the mods. The flat Hp is not bad make HP early and keep it.

I made 272whp @20psi on pump gas before my fmic. Im hoping now for the numbers you just put down with a 20g and all of your other stuff. I would get a logger and see what is going on, and fix your air fuel around 5k, dips to nasty rich.

OK im going to the dyno again next week and hopefully bring back at least 320hp at the wheels on pump gas at 20psi...

After reading all the post of everybody here thats given me their opinion....im thinking that my rich problem and the flat line was due to my head gasket leaking....because on the first dyno run I made I was making about 6 hp more and after this run I posted I blew the head gasket pretty bad....

I installed arp head studs and a new gasket...and Ive been beating on the car but I mean beating on it for a while and I took it to the track running mid and low 12 in the las 2 weeks so I think my probelm is fixed im getting the datalogger soon.....

as soon as I get the new numbers im going to post the here for you guys...

Not a big fan of nitrous (but hey it is FI, so I can't complain), but I hate VTEC. How much cylinder wall do you have left?!?!?

Should be really fast, that's for sure.

Well I dont remenber exactly cause I had the DARTON sleeves installed and then bored out to 85mm plus im getting in january a 94mm eagle lightweight crank to see how 2.2litres feel with 150hp NOS shot to it......

Basically im making my 1.8 into 2.2 litres so it should be interesting....

 

[krustindumm]

alright, it's been sleeved, i thought you bored the stock sleeves to 85, that would be...daring.

Yep the engine is ready for the power(I HOPE)

Are you interested in a b18a block sleeved to 84mm with pistons all you need is a crank and rods.....
Im selling it for a friend of mine he sold his car to get married and I kept the engine....
It was putting down 206hp with stock gsr head and cams with skunk2 intake manifold....
Well let me know if you know anybody cause its taking up space and im leting it go for $600 plus shipping!!!!!
Its like new if you are interested let me know I can get a pic

I'm a SOHC guy, I don't really see any need for the second cam. All the people I know have SOHCs or K series motors.

 

[madnezpr51]

Ok dude...
That's cool thank's anyway

im a SOHC, DOHC, honda, DSM guy..

why dont you like vtec? for a mild street car its a damn good thing to have..

the b18a/b/b20 in my opinion is the best honda motor to build.. especially for boost

i dont really see any need for the OHC..

Me too, I was just trying to say that I really like the D-Series, Honda's SOHC.

231whp, 12psi, stock D16A6 (non-VTEC) engine. And the kit is only $2075, yummy.

For a mild car yeah, as long as you don't boost it. And who likes mild cars

the b18a/b/b20 in my opinion is the best honda motor to build.. especially for boost

The Non-Vtec ones, sure, but jumping into an N/A cam probably won't give the best results (even if the stock VTEC lobes aren't too bumpy)

i dont really see any need for the OHC..

Pushrods aren't really that bad, but flat heads are.

 

[GaRn]

pretty impressive.. i was thinkin about buyin an si hatch(d16y8 i believe?) and throwin together a turbo kit to.. awd owns me though..

i have a friend that has a turbo b20 in a hatch.. 7 psi he makes just over 200 whp on stock everything.. pretty impressive stuff..

your car is considered a mild car.. i wouldt think anything under 350 whp would be considered mild, or in my opinion it is..

 

[DSMTurbos]

explain this knock box, the only way to read knock on a 2g is via dsm link

 

[krustindumm]

Mild in honda world is I/H/E and maybe a high flow cat.

pretty impressive.. i was thinkin about buyin an si hatch(d16y8 i believe?) and throwin together a turbo kit to.. awd owns me though..

Funny, my brother called me to tell me he was going to drive my car in the winter because his TSi sucks in the snow He does own me from a stop for sure, but we haven't raced yet...

88-91=D16A6
91-95=D16Z6
96-98=D16Y8

D16A6 has the best crank and Non-Vtec head of any D-series
D16Z6 has best head of SOHC VTEC (symetrical ports)
D16Y8 has worst of everything (asymetrical ports)
D16Z6/Y8 may have better block girdles than A6, but not as good of oiling to the crank.
Z6/Y8 also got a slightly higher flow oilpump

The Y8 head's ports are designed for fuel efficiency and torque, it has a slightly more agressive tune giving it more overall power, but requires more work to get to make large numbers. The ports promote swirling, which restricts flow at higher flow rates.

The block girdles on the Z6/Y8 are aluminum and tie in in more places than the A6s, which is steel. Kinda a tossup here, but honda does use a similar design aluminum girdle on the B18Cx motors.

Stock internal SOHC HP record is currently 302whp, held by a D16Z6, although the numbers should be repeatable by any D16.

yea, we just had our snow down here and it reminded me why i wanted an AWD ha.. if i didnt have my truck in 4wd i couldnt have made it, i guess its my shitty tires gettin bald(and rwd sucks in the snow)..

i guess there is no need for a bXXx motor, i recall a guy on honda tech throwin down 550 or so whp on a SOHC turbo motor.. so unless you want more than that, which wouldnt even be close to streetable.. or atleast it wouldnt be to pleasant driving the damn thing .. i guess SOHC would be the way to go.. if somethin goes wrong? no sweat buy another longblock for 500 bucks ..

your turbo setup looks killer..

 

[OB1]

Anyone else notice his torque/hp numbers do not cross at 5250rpm?

Did you happen to notice that the HP and TQ scales are not the same?

Lean how stuff works before questioning someone's integrity.

 

[GaRn]

ouch.. dont be so harsh people!

he could have been tryin to "catch" you or be a smart ass, but he could just be pointing somethin out..

Seriously eh?

So much for trying to learn something....
