Okay, I’ve been considering this as an option for squeaking a touch more horsepower out of the old engine, but I’m not sure if this is allowed in the STS rules. Am I able to put 92-93 cams in my 1990 under the update/backdate allowance, or does this only apply to the older vehicles? I just got back from running at one of the fastest set-up courses I’ve seen yet, which is what’s prompting this question. I’ll let the real SCCA guru’s tackle this one.
Nobody? :bump:
I thought they got rid of the update/backdate rule?
Update/backdate rule Permits you to make changes between the same make of car, model of car, and body style of car. This lets you take parts from any 90 Acura Integra 2 door and change them with a 93 Acura Integra 2 door. Same make, model and body style
Nino is correct. You cannot update/backdate a car. If that was the case then the Civic Si would be even more dominate. what you have is what you get. Engine wise anyways. Save the I/H/cat back. Get a rule book or go to this site .
Good luck.
92-93 spec cams give a little added hp to 90-91’s?
Yes, I’ve seen the pdf rulebook, but I didn’t find anything on the rule. If it no longer exists, then I guess I’ll scrap the idea. However, as a hypothetical question: If a part should break on my 90 Integra and I find a used part off of a 91 Integra, wouldn’t that mean that the part from the 91 wouldn’t be allowed to be used unless it fell under the allowances for the class I’m in? An example, you ask? Head cracks on my 90 Integra and I find a usable head from a 91 Integra. I’m not able to use this part and remain in STS, correct? I just want to make sure that this is, in fact, as ridiculous as it sounds.
It has to be the year of the car. In STS rules you get everything the stock rules have and then STS. ?SP alows update and backdate. That is why you can drop a Type R C5 in you G2 and get away with it in DSP. If you want to get an exact answer you can go back to the SCCA web site and find the Solo 2 board e-mail and ask them the question. Also, a lot of the answers can be found at SCCAForums .
Good luck.
Really? I thought that only applied to cars that were on the same line. For example, in DSP, the first gen Integras are on the same line as non-GSR second gens(Integra(NOC)('86-'93)). That means that you can swap second gen stuff into first gen and vice versa. The GSR and Type R are listed on their own lines.

From what I have been told locally(probably not the most reliable I know) in a car as the same name you can go up and back anywhere. We have a CRX HF with a Si built engine in CSP. Like I said though this is local info. If I get crazy I will check with the board for sure. My only gripe(sp?) on ?SP is the fact on no camber adjustment. Only what you can get with stock drop, etc.
Edit
Just checked on the moton site the Type R, GS-R, and every other Integra from '86 on up falls in DSP.
Okay, I understand now…Street Prepared classes only apply to the update/backdate clause. This makes much more sense to me, now.
I know that the Intgras are all DSP cars, but again, my understanding was that it had to be on the same line for update/backdate to apply. G2 non GSR motor legal in G1, but GSR/Type R motors not legal in G1s and G2s. Again, I’m not positive, but that’s my understanding of the rule.

EDIT: Section 15.1 C in the rulebook.
Okay, i see it now. Like I said The “local” rules are a little grey. Thanks for clerifying the difference. So, I can drop a B17 in the LS and be in DSP correct? Not that it would be an advantage. No torque.
SM here we come?!
Thanks Nino. What class are you running in now?
I’d tend to agree with the SM comment, but I’m going to go about it a little differently. I think I’m going to all-motor build the B18A1 and see how it does with some DOT-R tires and maybe some new coils. That will be a few years away, however.
That seems like a good way to go, although, it seems even better if you were to use an EF chassis.
dk91ls,
I don’t have a competitive car for autox this year, but when I do go to autoxes, I run in SM in my GSR. Damned ABS delete. :bang:

The way I look at it: You have to run 90-91 Cams, unless the newer cams are identical in part #, and identical by sight. The 92-93 cams aren’t the same part #, and they’ve got different markings IIRC.
As for engines, the motor has to be on the same line. 90-01 Integras (NOC) are on the same line, so for a DSP Integra the best engine would be a 98-01 LS motor. The GSR is on a different line, and the Type-R is also.
HTH
I dont think you can run a 92 and up motor in the 90-91 chassis wether its LS or not. The 92 and up cars have more hp and even though they are in the same class, your still making a hp gain with the parts and it doesnt matter if the parts are internal or not. You cant gain hp with the part period. In fact even if you put the 90-91 cams and intake manifold on a 98 LS motor in your 90-91 teggy technically you could be protested and would loose you place at the event. That or reclassed. And you defianlty can not upgrade to a GSR/ITR motor and still run in DSP. Mabie at your local events, but never at any kind of National level. We wont even allow that here in Idaho. Theres a lot of “gross misinterpetitions” out there, but theres no way you could get away with a R swap in DSP.
