LSD on H22 head w/ H23 block

[91-accord]

So, Does anyone know how the lsd system is installed? Basically, my brother had his prelude tolled into a shop and had them strip the whole engine to find the cause. He then turned down the work and ask the shop to put everything back together but they wouldn't even for the price that they had already charged for diagnostics, which was over $500.00. Anyways, the block is bad so we've decided to bring the prelude back to our place and install the H23 block with the existing H22 head. The engine is pretty much complete as of now. However, we have no clue or whatsoever about how the LSD unit is installed or goes in. It could be that there is some kind of bracket that is needed. But like I've said, I don't a clue at all. If anyone knows please let me know ASAP. Thanks!

the LSD is in the transmission.... nothing to do with the motor.

Actually, I'm talking about the ATTS (LSD) unit that goes into the tranny from the driver's side. Anyhow, we've decideed to just go with the H234 tranny instead.

Vehicle: 98 Prelude SH w/ original H22 head and H23 block on H23 tranny.


So, now that the tranny is well taken cared of, let move on to the
motor itself. Now that everything is finally installed, the engine cranks when we turn the key, but does not want to start! Two of my concerns are compression and ignition so the questions are:

!) When installing the head onto the block and setting the timing belts, how do you know the if the piston is at it's compression or combustion because for every two turns on the crank, the cams only make one turn.

2) So as we make our attempt to start the engine, I decided to check for sparks after several times of failure to start. I then pulled the wire coming from the ignition coil into the distributor and held in my left hand while holding onto a screw driver on the hand. As the engine was cranked, I slowly brought the screw driver towards the wire and there was nothing. Did I do this right??? If so, could this possibly mean that the coil is bad or maybe a fuse or relay somewhere that controls the coil.

i see. i dont know of anyone who's got the ATTS unit to work in an accord. not saying its impossible or never been done, but i dont think anyones done it yet.

It's actually a prelude, and I discovered that the ATTS unit will only bolt onto the SH H22 only. Not that wanted it on that H23 but it would have been nice. By the way, does anyone know the answers to my questions at all?

Check all of your ground wires and make sure they have good solid contact. Do you have a shop manual for the car and engine? It would help you locate all of the grounds and there should be a proper test for no spark.

If you have a shop manual it will help a lot. It amazes me how many people try to do swaps without proper documentation and overlook some of the more simple electrical stuff.

As for your timing, it would also be good to have a basic knowledge of how things go together before you try and put together an engine. There are specific markings on all of the timing components to let you know when the engine is at TDC of the intake stroke. There is only one way that you can put all the gears on with there key ways. Then you make sure that the arrows are all pointing in the proper directions (usually up or towards each other) Maybe someone will be kind enough to post up a timing diagram for an H23. I don't have the time right now, Sorry.

i hope you did everything your suppose to do for a h22 head swap on a h23/f22 f23 etc etc, if not your gonna have alot of leaks If the car started before without problems and your using the same distributor, then somethin mechanically isn't right( forget to plug something in?, bad connection). If your missing a ground the car usually won't even turn over, but check the ground for the harness on the thermostat housing. theres 3 main gorunds of course(batter (-) cable to the tranny and chasis, valve cover to chasis, and the harness ground i mentioned.

And the h23 timing marks are the same as the h22. TDC for the cams= Both arrows on the cam gears should point straight up at 12 o'clock. Either direction on both cams(on the face of the gear) theres a striaght indent that should line up with the surface of the head. Crankshaft should be a 12 o'clock when at TDC.(key way)

So far I checked and found two ground wire unattached. Got them two attached but still no start. Also, I did however notice that the original block (H22 SH) may have had two crank sensors while the current H23 block doesn't have any. Will this have any effect??? Please if some can help, feel free to include your inputs and thought. Thanks again for the following inputs so far. Please also, I am including my cell, feel free to text me @ 651 - 261 - 7379 Thank you.

well does it crank over? and just won't fire up or what? and codes/check engine lights? Not sure what computer yor using etc etc all that wonld be helpful if you really need help

[91-accord]

i'll tgry to get a vid later today

[91-accord]

Actually, I have additional information. That is I haven't installed the crank sensor because I couldn't figure out where it should go. Please help. Thanks!

[HaulAss247]

well you didn't say but if its a obd2 car which i think it is, since i don't remember the obd1 h22 having a crank sensor by itself. It goes right down by the crankshaft timing gear. Its works off the gear and sits inside the timing cover. good luck with that, don't know if the h23 gear will work for that since its a hall effect sensor. (basicly its a magnet and varies a voltage signal, with its magnetic field as the teeth on the gear pass it. When it sees a signal thats longer i think it is, it tells the computer that #1 cylinder is at tdc.)

Just realized your doing a g23vtec swap so you just have to figure out how to blot up the sensor where I told you since you should be using the h22 timing gear. Don't remember if the h23 as bolt holes for the sensor you might have to figure that out
