    Default Should NON-US motors be allowed in ST?

    Well, what do you think? if you have a strong position one way or another, I'd like to know. and I bet others, up to and including the PTB, would as well.

    Yes. The big first assumptions of the class - as I understand them - would be in no way compromised by this approach.

    ON EDIT - My answer might be different for STU vs STL.

    I said no. What problem is this 'solution' fixing? I am not sure any. Are you opening up a market of engines that will equalize the power/cc issue?

    Is it neccessary? What beneifts does it provide? Does it have the same effect for all manufacturers or just the ones 'you' (the collective you) like?

    For a rule change like this, I like to hear WHY, instead of WHY NOT. (Looking at this from an STL point of view)

    First, I'm not an expert. And second, I'm only concerned with Hondas. Plus, I'm certainly biased a little.

    That said.

    Why not?

    The K20a and K20a2 are almost identical. Most of the parts can be mixed and matched. Same with much of the B series stuff. One could build a JDM spec K20a engine using a K20a2 US block and few (if any) would know any better...

    That's what I'd do...

    Policing would be a B-itch.

    I bet if I stuck an SR20DE in my 240SX, I could go all season locally without anybody even batting an eye. Why? Cause it says Nissan on the valve cover and it bolts in stock. (The car came with this engine in every other country it was sold.) I can provide a bazillion pictures of this engine in this chassis, including a service manual in Engrish with drawings of this engine in the chassis and everything.

    The guys in tech can't possibly know every car and every US engine that's on the market, so it's nearly impossible to police this kind of stuff.

    I haven't been asked to lift my hood by anyone since I got my logbook for the car back in May. Of course I've only run regionals so far, but it's not like I'm an also-ran. I've finished in the top 5 overall and won STU in all but one race to date, as well as set track record at MSR-Houston.
    Nonetheless, I could have been running a freakin Chevy V8 in the car all season and nobody would know..

    But am I for non-US engines? HELL YES. Nissan's engine options under 3L are crapola for the US. everything is a long-stroke truck engine, or an ancient iron block designed in the 60s. for a supposedly modern class and philosophy, Nissan is stuck with engines from the stone ages.

    Do I realize it would open up the class to all kinds of other uber-engines? You betcha. Bring 'em on.

    Let's go back to the rules when they were originally made for the class: (This is STU-specific..)

    Normally aspirated:
    Under 3.0L displacement
    12.0:1 max compression
    0.6" max valve lift
    6 spd max transmission.
    weight = 1.1lb / cc displacement
    Go.

    Turbo?
    stock turbo for the engine it came on. no conversions.
    pick a tranny, 6 spds max.
    weight is based on inlet restrictor size placed in turbo.
    Go.

    For whatever engine you have, you must a factory service manual in English in your possession.

    Very simple to police. All of the components are easy to measure and/or verify with a factory manual. Voila.

    Policing is 100% moot. Tech has NOTHING to do with legality. There is no difference between STx with non USDM stuff and IT right now. It's up to the competitors to know their competition. It's also a punk move to run something illegal like that. You want your ashtray that bad? Please.

    Not 'why not'. WHY? The first real reason I heard was to provide a selection that was much better suited to 'racing'. I'll buy that some.

    Mostly I just see it as providing SOME a better choice and not all. I like rules that help or hurt everyone.

    Dont' have a coronary over there-- just voicing my opinion here. We're all allowed to do that, no?

    The only time I've lifted the hood on my car at the track is to check the fluids. nobody has looked under my hood or even asked. If they did, I've got nothing to hide. My car is 100% within the rules and I plan to keep it that way, competitive or not.

    If I were the cheating type, it would be easy to do and not get caught- at least for a while.

    Why not have ANY motor of the displacement allowed by the class? Want a 2L Honda in your Dodge, why not?

    If the Honda has non-US engines of similar displacement that fit the rules, but the VW does not, why should the VW be limited? Why shouldn't the VW be allowed to run a Honda motor of displacement that fits the rules?

    But Ron has a point. We draw lines between "makes perfect sense" and "silly" all the time (see also, WASHER BOTTLES). They are arbitrary. That's why it's so damned important to get the first principles clear before the details are decided. This is (again, as I understand it) a pounds-per-cc class. At that point, who cares where the engine came from?

    Matt, no issues. Many of us hate it when the 'policing' flag is thrown. It's just not applicable. We can ll do that stuff now. We have to police ourselves.

    Again, in order to get my vote, I like to see a real rason TO do it...because in this case, you are creating a situation where finding specifications in order to prove legality will be much harder.

    My vote is NO. We have a few people stating that their US engine could be replaced for 1000 with a JDM-yo whatever and they could make a million hp and run for 12 years etc etc!! I read it as "I can win with this engine and not spend alot!!" Then somebody will go out and find some obscure (read:expensive) euro spec RS500 what-have-you and kick their butt, then we add weight to them or something to slow them down. That was already mentioned somewhere on this board. This is the "case by case basis" I have heard about. Then try to put the cat back in the proverbial bag.
    Open up ignitions, air intakes etc. keep the compression and cam specs, go out develop them and run em!! Keep the US engines!!
    Rant off!! Anybody have any valium??

    *IF* non-USDM engines were to be allowed in Super Touring, approval would be on a case-by-case basis and only after receipt of clear technical documentation of the engine(s) (e.g., supporting FSM data). It would not be a willy-nilly Wild West blanket approval of any random engine you'd like to try.

    reasons to: lack of viable entries for STL that don't say "honda" on the valve cover. seriously, the only real option seem to be a Toyota 2ZZ-GE or some 2L motors (SR20DE, MZR LF/Duratec, 2.0L Ecotech) and MAYBE a 1.8L mazda BP, or BMW. the new fiesta motor might give ford a 1.6L worth considering. this is not a growing segment, in general, in the US. diversity in the class will need more options.

    STU - less of a need, however a number fo popular options exist and are well documented. because americans had to have torquey motors, the standard motor in the rest of the world was typically one a bit smaller and often much more suited to what we are doing here.

    existing cars - there are JDM/EDM swapped cars runing around in track day clubs, marquee clubs, and NASA. some of these would make good entries for ST. we aren't hereing their votes if they aren't yet members, either.

    reasons for, under "why not":
    class concept APPEARS (no philosopphy yet published) that displacement is close to directly proportional to power under a blanket CR/valve lift scheme. country of origin of the motor doesn't matter in this scheme, why should the market it was sold into?

    for SOME makes this could lead to affordable, reliable engines that fit well into the general scheme. some of these are evolutions of USDM motors (SR20DET, RWD SR20DE, SR16/20VE, 4A-GE 20V, later 3S-GE toyotas,...) others were never sold here at all (RB25DET, VW V5s, the rumored physics inverting rally homologation motor made of gold, whatever). speclines can be used to put over/unders at a weight in line with their actual power output.

    reasons against:
    "unnecessary" which I think depends on what car is in your garage

    the arms race to import the physics inverting motor from above.

    My biggest issue is the potential lack of availablity of the specs for competitiors to police each other.

    then support case by case allowance with sufficient US language documentation being a prerequisite. I think everyone on the FOR camp would be in support of this compromise.

    IMO, that's just as nonsensical as allowing the physics-defying uber motor above.. Almost every JDM engine I've seen used in the states has a pretty popular following and easily available documentation. I'm sure there are always exceptions, but the internet is a wonderful thing when used for more than just porn and arguing on forums. Information is easy to come by if you know where to look.

    Right. I think you are looking through this with JDM-colored glasses. Engines from other countries with a much smaller enthusiast following could be problematic.

    Just trying to weigh the potential benefits with the potential problems.

    Yes, I'm looking with that slant in mind.
    Pretty much the same could be said for European cars as well, and I'd venture to guess most German or Italian makes have manuals available in English as well. Of course I could be wrong there, but I'd guess with Great Britain right next door, the manufacturers would supply service manuals in multiple languages.

    What other cars would you expect to see in the class aside from US, Japanese, and European makes? I'm not expecting to see anything Russian or Arabic or Piglatin show up to race since those cars weren't available for sale in the US and thus violate rule #1.

    I vote yes. It would enable a broader range of marques to be class competitive. More options, more racers, more interesting to participate or watch.

    I could see the need for approval following documentation of tech specs, but failed to vote that way.
