really un sure of motor

[White90EF]

ok i have a 90 std hatch and im not sure what motor i have it seems wrong to me for some reason. i have a d15b block (not d15b 1,2 or anything) so what does that make it? cuz its DPFI every thing is PM5 head and ecu....im probably asking a dumb question?

I dont understand what your trying to ask....maybe im a dumb ass...haha j/k

 

[White90EF]

lol no your not but i thought that was funny.......well it has D15b block but the head is DPFI so i dont know if the person before i had it F---ed it up or what or if its supposed to be that way?

 

[bizoneoeh]

if you have a std then it's supposed to be dpfi

 

[White90EF]

yea i know but is it supposed to have a d15d block

 

[ej2rey]

sum b4 probably blew tha block n switched it for a jdm d15b block only n kept tha d15b1 head

there is no such thing as a d15d

 

[White90EF]

opps my bad spelling errs lol....at least you knew what i meant....so in that case would i have a little more power than i think i have cuz of that....more than the 70 stock horses or no because it still has stock head

for one, you have no idea what motor he has so how can you tell him his motor is rated @ 130hp let alone a motor that came with vtec.

opps my bad spelling errs lol....at least you knew what i meant....so in that case would i have a little more power than i think i have cuz of that....more than the 70 stock horses or no because it still has stock head

it doesn't matter because you're still dpfi and no one still has no idea what d15b you have. There are a few d15b's with different ratings.....

our site has so many featurs and info that all you have to do is search for you answers because they are already there most of the time.

Well the stock d15b is 9:6.1 compression ratio and a stock d15b1 is 9:2.1.

So I doubt you'll be getting much hp from that block if any. Specially cus you're still dual point injection.

 

[White90EF]

ive only seen it like that on one other can that was getting its head fixed but that was it every other motor i see has a number

 

[White90EF]

yea its not really a big concern or issue i was just see if anyone knew why it could be set up that way but thanks for everything

 

[dtgrowl]

for one, you have no idea what motor he has so how can you tell him his motor is rated @ 130hp let alone a motor that came with vtec.

he said d15b without a 1 or 2 or anything. so i gave him the info on the d15b. i didnt say "you car pushes 130 hp".... source is wikipedia. just giving a bit of info to someone who requested some. i dont know what the previous owner did. All i know is he said "d15b"

 

[bizoneoeh]

yeah and on the engine code page I posted above the only d15b is a motor that had a carb. The other d15b motors on that list have a question mark behind the b like so..... d15b(?) meaning that a number should actually be there. I've never owned a JDM d15b so I can't tell you from personal experience.

 

[White90EF]

no your fine....thats the first thing that i thought when i got the car i was like "oh yea" but after looking around a bit its like oh you have 70hp i was like damn but nothing really matched up so thats kinda why i asked

yeah, more than likely you have a motor that is rated between 70-100hp but that's what they are rated at. I'll bet my left nut that even if you had a jdm d15b that is rated @130hp that it's not making more than a 100hp. You can never go by what your motor is rated at. your best bet is to go to a dyno to find out the numbers AND even some dynos like a mustang dyno don't put out the right numbers.



even if you did convert your dpfi into mpfi, you're still not going to feel a HUGE difference.

 

[White90EF]

ok with those numbers would i be able to beat a b20/vtec 92 hatch vtec not working....lol.....cuz its my friends car i didnt think it was possible but i did

no!


he could give you a 1/4mi head start and you would still lose. Your motor is not made or built for racing, it's built to go slow and save gas.

 

[White90EF]

lol i know thats what made think i have a better motor than i have....but did beat him
