On my 91 Civic Si, can I legally run the 88 CRX/Civic lower control arms on my 91 car so that I can use the Type R/88 CRX rear shocks (remember that 88 cars had the same LCAs as the 97-01 Integra Type R)?

I'm hoping so, as this will save me some cash when it comes time for shocks.

 

No, you can not change out LCA in STS.

 

But what is the update/backdate policy like in STS? What's stopping someone from using the 88 LCAs on a 91 car of the exact same model?

 

Actually, that is a good question. I forgot about the update back date. I am not sure if it would violate any other requirement though.

I would go to the STS site and ask them there...Steve Wynne and several other members on the STS board frequent the site.

 

What's the link to the STS site?

 

The update/backdate is almost identical to the SP rule. It uses the SP index to determine which cars may update/backdate with each other.

Your Civic is not listed with the CRX, so it is not legal.

The listing is as follows:
Civic Si (89-91)
Civic non-Si and CRX (88-91)

Not sure why they are seperate, possibly a mistake. Contact the SEB for clarification (get the email from http://www.scca.org).

 

I found this that may help

A. Equipment and/or specifications may be exchanged between different years and models of a vehicle if:
(1) the item is standard on the year/model from which it was taken,
(2) the years/models are listed on the same line of Appendix A (Street Prepared Classes)
The updated/backdated part or the part to which it is to be attached may not be altered, modified, machined, or otherwise changed to facilitate the updating/backdating allowance. The updating and/or backdating of engines, transmissions, or transaxles must be done as a unit; component parts of these units may not be interchanged. Cars not listed in the Street Prepared sections of Appendix A may not be updated/backdated until approved by the SEB and published in SportsCar magazine.

When did you get a 91 Civic????

 

I'm checking to see if the 88 Civic Si came with the same LCAs that the 88 CRX did. If that's the case, then it looks like I can use those arms then?? Who knows--I'm going to need to email someone on that I believe.

Oh, I picked up the 91 last weekend. Clean little car.

There was no Civic SI in 1988, it started in 1989. That should not matter as long as the 88 Civic (non-si) is listed on the same line and is the same as the 88 CRX as you said, then you will be able to use it.

Oh, I guess Stage One cover this alreday above.

Ok, all 1988 Civics/CRXs had the different rear LCAs. Since that's the case, can we come to any conclusion on the legality of the swap on a 91?

 

You cannot do this legally. Neither the CRX nor the Type R are legal in STS, so update/backdate is not allowed. If they were legal in STS, then you could.

 

Still no, your car is listed as "Civic Si (89-91)". The others have a seperate listing.

The question you should be asking now is, "Why is my Si listed seperately from the others?" Write/email the SEB and see if there is a reason, or if it was just an oversight. Why would the CRX Si be listed with the others, but not the Civic Si, makes no sense to me.

 

No, you're missing it. The 1988 Civic hatches/coupes/4doors came, bone stock, with a slightly different rear LCA. This rear LCA happens to be exactly what honda used on the 1988 CRX's and, later on, the 97-01 ITRs. Therefore, if all 88-91 Civics are listed on the same line, then you can use parts interchangeabily between any year listed. If that's the case, I could use the 1988 LCAs on my 91. I could also use the 1989 Si hatch doors as well because they are a bit lighter than the 91 doors.

 

No, you are missing the point...Look at stage ones post again. The Civic Si 89-91 are listed on one line and the Civic 1.5 (88-91) are listed seperately. For you to be able to use anything from an 88 Civic, the line wold have to read "Civic 88-91 all" which it does not, so they are not on the same line, so you can not use the LCA's from an 88.

The point here is for update and backdate, you can ONLY use parts from a Civic Si 89-91.

 

I didn't say it was legal or illegal...I was just clairfying the question so I don't think the point has been missed on my part.

Anyhow, we'll see what the SEB says is the reason for the different lines because I sent them an email.

 

I use to own a '87 Civic SI, that was the 1st year for the SI.

 

Sorry I meant for that generation of civic, The Si was skipped for the 88 year, that is probably the best way to look at it

 

Sorry you confused me, cause your original question was whether it was legal...I thought we were still discussing that.

 

Here's what I got back from the SEB:

I am not sure how to answer your question, because it strikes me as odd too,
now that you have pointed this out. The current arrangement would allow a
CRX Si engine (same as a Civic Si engine) into a Civic DX, as well as other
CRX Si components, but parts could not be interchanged with a Civic Si. Does
seem odd.

I have forwarded your letter to our SP Committee, which includes a couple of
Honda gurus. Hopefully we can get this clarified quickly.

So, we'll see what happens...
