88 crx Hf - **VTi** swap

[88hf]

I'm reusing the hf transmission as well, I would use my dd, but then I might be without transportation if everything doesn't work immediately. Also it seems advisable to upgrade the brakes when just about doubling power. Don't know about the vacuum canister/ vacuum lines, I've got all the newer ones from a junk car so I don't have to try and make the old stuff work.

well, i just commited to remanufactured da (92-95 integra) loaded calipers and master cylinder. Hopefully I can find the booster used and not pay $150 or more. Other than that need axles and a new radiator.

Got'cha on the vacuum lines.

As far as the brakes are concerned, I am about to put on rear disc brakes (from an SI) and then change the master cylinder to increase brake pressure. I am afraid to change out the front brakes because the hf has specific axles and spline count.

How are you using DX discs? I thought that they share the same hub as the SI and that the axles are the same as the Si axles, which don't fit into HF trans.

inner spline count is the same its the outer spline count that is different and requires changing the hubs to use the larger axles with hf tranny.

I guess that will be my upgrade in the near future. Since I plan on auto crossing I guess I will need to go with the DA hubs. Do you know if those axles will slide into the hf tranny? I know it is all Honda but seems like that would be stretching it since that would is a different series engine and transmission combo.

I don't think the da axles work, think its civic axles. But maybe they do, iunoh.

[88hf]

da loaded calipers are on closeout at rockauto... $40 for the pair plus shipping. Closeout, don't know how long. Also, oreillauto.com shows inboard spline count as 25 on both hf and si cv axle, but 23 outboard spline on hf and 26 outboard spline on si. DA inboard spline is 27 so yeah, that won't work also looks like newer civic axles although the same spline count are about an inch longer on right side left side is pretty much same length though.

Happy Labor Day!

Thanks shorty, No, i have a manual transmission. my question is how to know if a wiring harness is for an engine with CVT or manual transmission.????
But seems like i will be a absent from here because i am working in flood affected areas here in my country. we had the worst floods of our history and a very large number of my country folks are in a very bad shape. i'll try to keep in touch with forum. i'll appreciate your reply to my question as i have a uncut wirng harness with two selonids connected to it so it is a P2J. all i want to know is how to tell if it is for CVT or Manual????

If you do have to pj2-003 ecus on hand, sell them on ebay or something and make some money off of them. They are extremely rare. Or be generous and swap with someone (plus cash) for the cvt ecu.

Either way, it should not be difficult to modify. Most of us here haven't seen 1 original harness much less know the visual difference between the two. How did you source the harness?

Should have the rest of what I need to install the z7 beast Monday, although I do have a little side project to complete before slapping her in. I will be making my own engine mounts from Shore A 70 polyurethane rubber. I'm also adding black light reactive compound to the rubber when mixing.

Sorry to hear about the flooding. It sucks when people act like it is a communities fault for living in a flood prone area. Wish you all the best in your efforts to help. That type of devastation is very stressful to be involved with.

How many people who have visited here have this engine running? Hopefully I will have mine operational soon and can reorganize the information one last time!
