VitalSpeed_CRX Posted May 1, 2007 Share Posted May 1, 2007 Hey wassup everyone. I'm new to this forum.(HI) This is my setup and whats being added at the moment. Honda 1989 Dx D15B JDM/EDM Vti VTEC,(Around 35,000-40,000 miles on it) Automatic-(Everyday used Car but still looking for speed) JDM Racing Header. N1 EXTREME Full Catback Exhaust System ODB1---P84 ECU OEM WIREHARNESS(1989) Need 2 upgrade. New Radiator. Upgraded Cold Air Intake. All around Brake upgrade.(Rotors/Drums/Calipers) All around Parelli tires on stock CRX 15" Rims.(Spray Painted Black) Link to my Cardomain profile. http://www.cardomain.com/ride/765242 Q1: So there you have, it not sure if I forgot anything. A few things im still lost about. I know I have to upgrade my Harness for the Vtec to kick in. I'm not going to rip out the OEM one but will like to install the tips and have my mechanic wire it up.. Just not sure which to get. OBD1/OBD0 ---or--- OBD1/OBD1 ---or---OBD0/OBD0 ---or--- OBD0/OBD0(which im sure thats whats on it now) just not sure how the CRX wireharness runs. Im thinking I should go OBD0-OBD1 since the wireharness are OEM(89).My new ECU came with the harness but the wires are cut do i need to buy harness?. Q2: Im also thinking of going turbo for the fun of it. I know I said its a everyday used car and also a automatic but also looking for a sleeper ...Im sure I got more HP with all the Bolt-ons and mods.. Is there anything I should buy or get ready before I install a Turbo?. (About 8-10 PSI T4). Can I just put it on a turbo without having to worry about blowing my motor?* (*with the setup I have now*) Hope to hear from you soon. Thanks for your time.

cranny Posted May 1, 2007 Share Posted May 1, 2007 id swap a different engine in it personally. never heard of a P85 ecu. it should have a PM5 in it. you dont have to worry about vtec kicking in cause you have none. and no you cant just bolt a turbo to the engine , lots involved. you dont need to upgrade your wiring harness at all.

VitalSpeed_CRX Posted May 1, 2007 Author Share Posted May 1, 2007 Yeah im sure I could of put another motor in it. Any one else would of too..It's a automatic im sure if it was manual I would of put a GSR in it. But like I said its a everyday used car. The D15B does have Vtec (SOHC). Its from a 92-95 EX which came with Vtec(only models that had sunroof and power everything).. the head on it says Vtec aswell. the ECU and motor are both from japan.(JDM SPECS at the moment) The ECU says 92-95 OBD1 Civic eti (Vtec-E in America).I wanted a crx since I was 11 so I have had plenty of time to do research. The PM5 is the OEM (89) ECU. The PM5 ECU is not programed for Vtec. I had to upgrade(P84 not P85) for the motor to work right.(Vtec) and yes I do need to upgrade my Harness so the right information can be sent to the rest of the car. As Far as the turbo I know I have to upgrade my pistons and other stuff.. my question was. What else do I upgrade before I put in a turbo?. I have a personal mechanic whos going to tune/dyno the whole thing for me. I'm sure he can answer my question but I rather not bother him with questions and let him work on my car.

CRG7 Posted May 1, 2007 Share Posted May 1, 2007 1993 D15B2 SOCH Vtec (Around 35,000-40,000 miles on it) D15B2 is not a VTEC engine, and you don't have a '93 B2. You have the stock 88-91 Civic/CRX DX engine. Your VTEC doesn't "kick in" because you don't have VTEC. Your wiring should not have been touched, and it is OBD0. As Cranny said, you should have the PM5 ECU in there. This is all stuff that you should know if you've had "plenty of time to do research" on the CRX. The D15B does have Vtec (SOHC). Its from a 92-95 EX which came with Vtec(only models that had sunroof and power everything).. the head on it says Vtec aswell. No, the D16Z6 is the 92-95 EX/Si SOHC VTEC engine. Also, not all of the Z6's had VTEC written on the valve covers. Link to comment Share on other sites More sharing options...
VitalSpeed_CRX Posted May 1, 2007 Author Share Posted May 1, 2007 Waddup.Thanks for the input. So I called up my mech. He said it is a D15B with a Vtec head and it will have Vtec with the right harness/ECU(I have the right ECU).So im still lost on which harness to buy. Now im just not sure what has more or less or equal HP a Stock D16Z or the conversion.Paid $300.00 for the motor so I cant complain.My Timing belt skiped and blew my old motor.I havent tried out the new motor since the car is being fully rebuilt as we speak. So I cant tell if Vtec is kicking yet.I will find out in about a week.I was going by what was on the paper work for the motor.Since the only time I took a look at it was when it got droped off.As far as the turbo anyone got any input on what to upgrade before I get one? Im sure people are thinking why even put the turbo in. umm cuz I have the money for one and would like the extra speed and who dosent like speed....Thanks again peeps.

VitalSpeed_CRX Posted May 1, 2007 Author Share Posted May 1, 2007 Thanks 8MügeNcRX9*DuB..

VitalSpeed_CRX Posted May 1, 2007 Author Share Posted May 1, 2007 From what was on the paper work for the motor it said "used 92-95 sohc vtec". when I was ordering it over the phone the guy said he had a 93 in stock which had about 30-40 miles on it and thats all that came up on his inventory. for $375.99 +S/H.. so I said hell yeah. (others where asking 600+) from what he said im saying a 93. on page 3 of my cardomain profile you can see the ecu I got. http://www.cardomain.com/ride/765242 ..I guess I got the right one with out even thinking about it.Thanks again. And from what I found my motor is better then the US B16Z Link to comment Share on other sites More sharing options...

And from what I found my motor is better then the US B16Z What the hell is a B16Z? I'd be a little worried if you say others were asking $600 for a motor that you paid $375 for, including shipping. Shipping can cost $300 alone at times. Maybe you were thinking about the original motor, or maybe you're just confused on the whole setup that you have right now, I don't know. If you have some kind of mechanic working on your car, then ask him what kind of wiring setup you'll need since he obviously knows (or at least should know) what setup you actually have.

Joe W Posted May 2, 2007 Share Posted May 2, 2007 Yeah i dont know d15b run 500 on hmo not including shipping. Also if you have a 93 SOHC VTEC motor it could be: D15B-VTEC->Found in: 1992-1995 Honda Civic VTi EG4 (Japanese Market) D15Z1-VTEC-E->Found in:1992-1995 Honda Civic VX or 1992-1995 Honda Civic VEi (European Market) D16Z6-VTEC->Found in:1992-1995 Honda Civic EX/Si, Del Sol Si, 1992-1995 Honda Civic ESi (European Market) I dont know if this helps but there it is.

VitalSpeed_CRX Posted May 2, 2007 Author Share Posted May 2, 2007 There I fixed the typo fliped out about D16Z6 not B16Z...SORRY! I looked at the bill $375.00 for the motor shipping was 135.55 Total $510.55 since he didnt have the motor I wanted he gave me a discount. S/H was from CA to NV. Others where asking about $600.00+ since they where shipping from NYC/FL to NV D15B-VTEC->Found in: 1992-1995 Honda Civic VTi EG4 (Japanese Market) But I will double check 2 make tomorrow to be on the safe side so people like all over the forum. I was close to being right, give me a break. My motor does fking have Vtec and it is a 93. Sorry I didn't know JDM used different motor codes then US since I only did research of US parts. I'd rather have my mechanic just work on the car then bother him with question.I cant walk to the shop and dont want to call the shop just to ask a few questions. Thats why I came to this forum. Maybe I was a little confused on the setup I have now.Like I Said AGAIN I have only seen the motor one time and thats when it was dropped off and I was going by whats on paper,then the motor being in front of me. By agreeing with what others have posted doesn't help me out. The only helpfull person has been 8MügeNcRX9*DuB.. THANKS!!! Link to comment Share on other sites More sharing options...

For starters, watch what you say around here, and better yet, watch who you're saying it to. If you want to disrespect moderators, or regulars, you may want to consider another forum, as it's not tolerated here. B16Z is a more likely typo for B16A, what with the A key being right above the Z key. The $500+ total sounds better. You get what you pay for when it comes to parts, and if you had paid $375 including shipping, that would have been worthy of a warning flag. If you know your engine is a 93, and has VTEC, then great. And maybe mugen is the only person who has been helpful to you thus far, but when you're giving us the wrong information, it's hard to get help on what you need. Find out your setup, and report back if you choose to. You'll get the answers you need when the members here know what your situation is. Link to comment Share on other sites More sharing options...

Kicksome123 Posted May 3, 2007 Share Posted May 3, 2007 PSI doesnt kill the motor, the hp you get from it does, I would try to get around 200 tq from the stock internals on my engine and it should be about the same on yours, just make sure you get a good tune and have a good EMS. That much tq is really fun on that light light car but yea, make SURE you get a good tune... Link to comment Share on other sites More sharing options...
CleanGSR Posted May 3, 2007 Share Posted May 3, 2007 ^^ Exactly. That's such a common misconseption. 300whp on a T3 at 14 psi is no harder than 300whp with a GT30 at 9psi (just an example). People always think that a motor can only handle X amount of PSI when the X should be Hp. Link to comment Share on other sites More sharing options...
hondaswap352 Posted May 3, 2007 Share Posted May 3, 2007 only read as far as to what harnes you need..... if you have the obd0 to obd1 conversion harness on your ecu all you need to do is follow the wirs for the vtec and extend em, run them out to the engine bay and hok up your vtec and should work as long as the ecu is putting out signal...and if its the right ecu it should...

VitalSpeed_CRX Posted May 4, 2007 Author Share Posted May 4, 2007 The ECU I have for it, is a AT 92-95 Vtec-E (P84) Hope that extra info helps. SOHC VTEC-E Honda's next version of VTEC, VTEC-E, was used in a slightly different way; instead of optimising performance at high RPM, it was used to increase efficiency at low RPM. At low RPM, one of the two intake valves is only allowed to open a very small amount, increasing the fuel/air atomization in the cylinder and thus allowing a leaner mixture to be used. As the engine's speed increases, both valves are needed to supply sufficient mixture. A sliding pin, which is pressured by oil, as in the regular VTEC, is used to connect both valves together and allows the full opening of the second valve. Stock OEM harness right now (OBD-0) There wire harness and the Wire harness is going for $88.00 shipped. everything I have on my car I got off Ebay Link to comment Share on other sites More sharing options...
hondaswap352 Posted May 5, 2007 Share Posted May 5, 2007 yup can get some good deals on ebay :-) and those harnesses are easiest to get there... thats what i did at my shop till me and 2 of the guys just started making our own ( saved money and wast hard ) but hope ya get it done soon keep me posted Link to comment Share on other sites More sharing options...

Kegger Posted May 6, 2007 Share Posted May 6, 2007 Dude I think that you just need to take back from your car and think about what you are doing to it. D15B auto.... Not exactly the best combo for F/I. Swap to a manual tranny and at least a 1.6 motor. That way you'll have some reliability and people won't think your stupid. Edit: BTW there is no reason for you to explain any kind of VTEC to anyone here. We all know how it works and what it does, even VTEC-E. So you don't have to try to say one smart thing while all your doing is saying stupid stuff. Link to comment Share on other sites More sharing options...
