I traded my kinda beat up 90 crx with a b18a1 for a dead stock near virgin 89 Hf, I kinda feel like I am riding in a unicorn.

I think I am going to leave it fairly stock for now, however does anyone know if the 89 Hfs, have 2 or 4 valve reliefs? If it has 4 I might upgrade to a 16v head eventually.

It would be either 8 or 16. You should obviously have posted the engine code and even then you won't know until you pull the head and look yourself. Nothing unicorn about an 89 hf either.

I just meant that it is so dead stock. It has wear and tear of course, but it doesnt even look like a single wire has ever been cut, not so much as an air filter upgrade.

If it already seems like a unicorn, give it the power of eight thousand unicorns pissing w an ex trans and a vtec motor, old buddy hit 14s on street tires w lsd and stock z6 in like ....02 or 05. I javent seen a stock hf in forever.

Does riding a unicorn mean that you have one of those bicycle saddles for women that occasionally feature on specialist websites?

HF are all domed pistons and eight reliefs.
Thanks, since I cant change heads without changing pistons I will likely leave the drivetrain bone stock for now and just work on cleaning it all up and getting everything working. It should work nicely as my daily for my sitting in traffic heavy commute.

If I had the time or money for a swap I would just get straight rods and pistons for my b18c1 and a tranny shift assembly for my b16 tranny with LS 5th.

Hmm

When I see HF, I see Bone bitching about the seat mounts starting to rip at the mounting metal lol

Worth a check to go over body seams and such, as the HF's were lighter moreso for lack of metal, not options

Just throw in a close ratio box then. I find good deals on good motors at a rate of 2 or 3 a year and have never paid more than 200 for a vtec motor so if u find ppl lookin to swap u can score cheap known good 16v motors from time to time

88 all and 89 HF are the lightweights. I put the softer suspension back on as sealed seams are coming apart.

All CRXs seem about the same for body construction, my 90 doesnt seem any more or less sturdy than any of the 88s I have had.

The 88 seat mount issue is that the inside rear seat mount is several inches foreward compared to where it is on the later CRXs. With a larger driver and the seat slid back in the 88s it puts more leverage on that mount point, and it eventually collapses.

Let's see some pictures. I had a white 90 HF as my first Honda back in 2002. I wish I would have kept it. And as far as I'm concerned, in my area a stock clean hf is a unicorn.

"Clean" is a reach, it has some work to do before it could have that title, but it is certainly much cleaner than my other cars, although, that does not take much....

It is hard to believe that these cars were almost identical from the factory, they were both white Hfs, only difference was that one was an 88 and the other was an 89:




This is going back to all white as soon as possible:

It does have one problem I am not used to seeing with hondas, it has a minor engine surge at ALL engine RPMs. I am very used to the idle surge and what causes that, but this is less extreme than that, maybe 150RPMs at idle, I am curious if it has something to do with the EGR, since I have never had a honda that suffered through EGR before.

In what is probably the car surprise of the year for me, when I put in my glued together climate control, the AC actually worked and blew cold air.

hot damn!


does the AC low and high valves have adapters on them? If not, enjoy the icy breeze while it lasts, I think Texas has laws in place to prevent shops from simply recharging R12.

cuz you know, leaky R12 systems will kill the earth or some wild exaggerated shit

No, it does not look like it has ever been converted to R134a, also the guy I got it from said he owned it for over a year, but the AC had never worked because the climate control was broken and removed, but the guy he bought it from said it had worked before the climate control broke.

Unless he was lying about how long the AC had not been working, that means that it has not had any freon added in at least a year, maybe much longer.

When it needs to be serviced I will likely try one of the Hydrocarbon blends if I can get my hands on something that looks good, or possibly one of the other R12 replacement refrigerants. I have never been happy with any R12 to R134A conversion.
