Ok so currently I have a simple obd0 lsvtec swap, I'm wondering exactly what you need to run a b18cR in a hatch
The engine I'm picking up was ran with a obd1 setup so I know I need a obd0 to obd1 jumper harness, I'm also guessing I need a obd1 adapter for the dizzy
I'm using my current transmission setup but will a type r clutch plate fit my pressure plate?..... And also do I need a 4 wire o2 sensor and crank angle sensor which I heard obd0 vehicles don't have, any answers would be helpful and I have searched through out various forums I'm just looking for concrete facts involving my plans
And if anyone could giver a source to check engine vin numbers.
Also is 2500 a good deal for a rebuilt b18cR setup with no tranny just ecu

CRX_RR

just rebuild your lsv with that 2500. b18c5 are 10.1 cr. go gets some jdm itr pistons 11.1cr aftermarket internals and a honda b-series engine book and it'll teach you everything you need to know to rebuild the engine step by step. then at the end the ls v would definitly be faster and fresher more relible. and then for wiring i wouldn't even miss with that, i just go buy a obd1 engine harness from rywire or send yours in for them rewire it to obd1. its much more cleaner.

just my 2 cent

I hate ls/vtec set ups at least to me, so I can't go that route and besides I think converting and rebuilding an ls/v to the spec of a type r is more expensive. The engine I might buy is rebuilt with 0 miles so can't get fresher then that and it gas a gsr head with skunk2 valves, ret, and springs with stage 2 cams and I might be able to go lower with the price now for the wiring I'm getting a conversion harness from rywire I also believe you can't send your own harness either

My car has the original wirering with a jumper for the dizzy and a obd0 to obd2 jumper harness.

Edwin909

Ok cool so no need to solder anything for an extra sensor?.... And are you running a 4 wire o2 sensor?..... If you could explain to ke any problems you encountered with your swap it be really helpful

Still haven't answered all my questions, now they're talking about running 2 o2 sensors on obd2 when I'm trying to figure out if I need a 4 wire o2 sensor, the engine will be ran like an obd1 and the b series swap they show is for a eg which is already an obd1 I'm lookin for information concerning a obd0 vehicle because like I said before I heard that obd0 vehicles don't have a crank angle sensor and run a different o2 sensor

OneBadTurboCRV

What are you even talking about? You obviously didn't even look at what I posted. In there it shows the DPFI-MPFI swap as well as the OBD-0 to OBD-1 swap... Obviously OBD-1 only uses 1 four wire O2 sensor and OBD-0 uses a single one wire O2 sensor. I have no idea why you brought up OBD-2 at all... None of this is hard and has been done thousands of times. There is also litteraly around 50 write-ups or more - not including all the consolidation write-ups there are out there. Adding the sensors is part of a MPFI conversion and OBD-1 conversion...

All your questions are answered in the link provided.

To get the most from the new swap, you should consider having it tuned. There's a number of OBD1 ecus that can be socketed, allowing a ton of different tuning softwares to be used to dial the motor in properly. Plus, your tuner will be able to disable the 02 sensors so you won't have to worry about that. Spend that money on a good wideband with gauge so you can monitor afrs. As for the clutch, you will need to verify if the spline count/size matches the input shaft of the transmission you plan to use. And OBD0 vehicles have a crank angle sensor, but it's located inside the distributor as opposed to being mounted externally at the crank. I wouldn't use the engine harness that comes with the motor. Instead, I'd keep things simple by using the harness that's on your lsv. You will need a jumper harness for the ecu and distributor, an OBD1 ecu (one that can be modified for tuning), and OBD1 vtec distributor. Doing all this will get you the best performance from your swap and you won't regret it. Just my 2 pennies...

Edwin909

Wow thanks for the information, the engine comes with a p28 ecu and I Fo believe those are programable since I don have a tuner what do you recommend doing about the u2 sensor?.... Do I get a 4 wire one or do I have to run 2?.... And if I could pm you about the clutch for more help once I get the clutch?.... Oh and iforvor to add that if my current mounts for a b18a1 will fit the new swap?....

rd91sib18c5r

If your using 92 or newer tranny the clutch is the same. 90-91 have a smaller shaft.

crvtectim

Nobody close to you tunes Hondas? Well then, that sucks. If the P28's already been chipped with a tune for the motor you're getting, I guess you'll be stuck running that. However, since you're using a different transmission, the tune may be off slightly (different gear ratio and/or final drive changes the load/torque curve of the motor). Who knows, the P28 may have 02 disabled already so I wouldn't waste any money until you get all your parts, get the swap running, then see what codes are thrown and address them accordingly. Yes, you can use your mounts. Don't get rid of anything from the A1 until you've completed your swap. And you're more than welcome to pm me when you get the clutch.

Edwin909

Well I'm sure there are tuners around me but nine that i know about, I have to see if the type r clutch will fit on my rare transmission I don't even know what clutch goes with it to be honest, would recommend using my old injectors or deleting my resistor box fir the itr ones?.....

crvtectim

If you're running a cable B-Series transmission, you can source a new clutch kit from a 90 Integra LS. You'll be fine using your old injectors so leave the resistor box alone.

Edwin909

Well I'll look an ask around if the Acura ls clutch will fit my a1 clutch I don't see why it shouldn't since the only difference seems to be the final drives, but what are the benefits of deleting the o2 sensor

crvtectim

The benefit for you is that you won't have to waste the money/time on a 4 wire 02. Tuning is a must for you to take advantage of the stg. 2 cams and transmission swap. That's why I said don't worry with the 02. It's throwing money away that could be spent on a wideband 02 sensor with gauge since the tuner has the ability to disable the stock 02. And you will never have to worry with an 02 code again.

Edwin909

How much is a wideban o2 sensor?...

Edwin909

Wow I posted wrong info, I'm actually looking to get an itr setup with a gsr head that has itr spec cams, valves and springs not skunk2 I got confused with another engine I was looking at, but my budget is around 3000 so is that enough to get the engine in my car and running with no problems?...

ef yu

not to be an *** but you can just google'd how much it would cost for a wideband o2. Discover things yourself. Stop making others do things for you when you have the same tools as everyone else.

Edwin909

You weren't an *** at first but then you had to finish like an ***, I only asked him because he could seems to have one and recommend me the brand and price, I was just looking for a ballpark price, now if you don't have anything positive to contribute to my plans please don't post

OneBadTurboCRV

$1 million + diamond encrusted and display...

Seriously, They range from $150 to over $500 easy... You could have hopped on eBay and looked or something. Which one should you get? That all depends on what exactly you are doing - for your setup a AEM UEGO (the cheapest one)... or probably just a LED light show with a heated O2 sensor.

Edwin909

1 mirrion dorras?.....
AEM does sound good I also found an innovate one for 160 but I guess I'll ask around for opinions

OneBadTurboCRV

Innovate is good but I would prefer the LM-1 or LC-1 or their latest one if I was picking their brand.

Edwin909

I'll look into it, it's just that I don't want to spend 160 on one if I can I want to only spend 2500 to get the engine in my car up and running
