Have a question about D15b2

[gleiva]

Ok well for starters I have a 95 civic with a D15b2 Vtec I have tried to do some research but can't find much except the same things over and over
my questions is that since I have Vtec in my D15b2 that would be a mini me head swap right and if it has D16 internals in the motor how much horsepower does this motor put out if soand if it doesn't have D16 internals how much horsepower is it putting out

[nyenye09]

hey whats up bro..

ok, heres my take- You have a D15b2 block that prob. came out from a Civic or CRX (88-91), these are DPFI engines non-vtec ofcourse and from what i know they are pushing about 80 HP to the wheels and about 91 HP overall..

You said you had a Vtec head, now first and for most, you need to make sure its even working and connected, if this is the case, the Vtec head should bump your HP marker about 30 HP..

Now for the D16 Internals, depending what actual pistons you are running, i dont think you are gaining much HP out of having D16 stock internals, you might actually be the same, but on the positive side you might be bumping your compresion, if you knew from what D16 you actually had then we can pin point your exact compresion. (I did alittle resarch, go to www.google.com in the search bar put in "Honda Engine Codes List" its the 2nd result, click it and see your diffrent compresions.)

ok so based on this info, your probabley lookiing at around 120-130 HP.. also depends if you have modifications, like intake, headers, exhaust, some ECU tunning.. do you?

oh and yes it is called a Mini-Me swap.... hahaha

Hope this is helpfull... :eek:

[gleiva]

Yea this helped I have short ram intake that's it I no that's not much but yes your info did help me thanks a lot

[gleiva]

Also when would vtec hit and I look on the ecu to see if it is hooked up and running right

[lowNslow]

obd1 p28 hits at 4800 i believe.....correct me if im wrong. i dont wanna give false info

[gleiva]

alright thanks for the info I'll have to listen for it then cuz I swear sometimes I don't hear it crack

[lowNslow]

Lol Theres really no "crack" in a single V. Its just kinda like mmmmmMMMM lol. I had a Y8 with I/H/E and the only way i really knew i hit V-tach was lookin at my rpm's

[gleiva]

well yea I no there is no crack I just call it that and thanks for the feed back

[nyenye09]

obd1 p28 hits at 4800 i believe.....correct me if im wrong. i dont wanna give false info

sounds right to me... :rflmao:

[smooth]

yes vtec engages at 4800 rpms

haha V-Tach.. nice one, and from personal experiance the day that i hear a clear croosover on a SOHC VTEC is the day the world ends.. haha ok ok not that bad, but single slammers dont have much of a "loud" VTEC croosover, you really have to be listening and even then itl be hard to hear it.. haha kinda sucks though haha :(

Ok i just got your PM, well to be honest i dont think that not having am muffler would help, i actualy think thats a bad thing.. iv heard that hondas actual need a full exhaust system, from the header all the way back, cuz they need back presure, but dont take me up on this.. haha

even with the intake i still think your in the 120-130HP range..

a little pointer.. i would add some headers, a stage 1 camshaft, cam gear, probabley a nice LSD, nice clutch some bigger injectors, and a good street tune.. i figure with this set-up youd reach a respectable 150HP to the Wheels, and would be fun to drive and some what reliable..

or you can just slap a turbo on it.. but not reliable what so ever.. i mean its a single cam! not hating cuz i love them but lets just keep it a that..

there are alot of things you can do to bump your HP its just based on how much $$$ your whiling to drop, if your like me and save up a piece at a time, i take my time and do it right, just some advice, and remember single cams arnt the top dogs but if you do it right itl be good to you.. hahaha -personal experiance

x2!

where is the arco you meet at in phx

D15B2 motors have what is called VTEC-e. It is a three stage VTEC system designed for FUEL ECONOMY and no performance what so ever. Get yourself a Z6 and be done with it.

[gleiva]

well my head is a z6 head I have the mini me head swap and that was done by the person before me and right now it's cheaper to just stay like that then to swap and if I could afford to swap I would do an Ls swap

Wrong... D15B2 motors do not come with VTEC-E..
