I have a 1991 Nissan 180sx and i was looking at rules for time attack, and from what I see my car may not be allowed because its not made in Canada. Is that right? That would be very disappointing because the main reason i got this car was from track use.

Also who can i find out info about if my driving school is still up to date, Im trying to get everything registered so i can lap and solo this year with my car.

Also who determines the PI # of my car is that done during tech at track? It is modified and I believe I have to show a dyno slip because i run more boost.

Any info would be great thanks.


Thanks
Jeremy Simmons

Yes RHD cars are permitted in Time Attack.

When was the last Time Attack or Lapping Day event that you did?

well its been 7 years since my last lapping event i been away with work in the army but now I'm back in the area again. Ive had my on the track in Ontario but would love to see how it does in time attack.

Pending on when and what you did at other tracks is the main thing. Rules state you keep you lapping and time attack licence for ASCC/Arms. You must compete in 1 event every 2 years. So you would need to do the HPDS. (in may). But if you can prove you have been running events at other tracks and hold a curnent licence that can be verified by the club you were running with, you may be good to go. This may be a good question for Brian Gay.

Other then that yes RHD cars are good for time attack. You have to complete the sheet in the time attack classing section. And I believe we went throu this last year but you have to send a copy of the dyno sheet and spec sheet to someone in Ontario and they will class you car accordingly. (someone correct me if I am wrong). Ill try and find the info need.

hmm i had to contact them to update the list seems that 180sx is not on there yet. i dont see the form to fill out is it just online, i cant select my car yet so i cant see that far.

thanks dave i guess i have to find a local shop and get some dyno runs down to submit too. and i hope that wont push my pi over the limit for a cage its already borderline and i want a cage anyway, but not this year i dont have that money for this season, if so ill stick to lapping do get used to the track again. I am just waiting on my ascc id number and then i guess ill registrar for the hpds and get the car out of storage and check it all over.


thanks again.

ok i sent them the info specs on a 1991 180sx so once they update it ill be able to get that online form completed. also i need to find a shop that will dyno my car once i get it ready next week, what is a normal price for dyno run? and dose anyone know a good place in Fredericton or near by i could get that done?

Hmm i took the car out of storage and sadly has a possible slight rod knock im going to check out lifters but i may have to pull the motor and i wont be able to make the school at all now. man that sucks.

Ill start work on it in the morning, i must fix this i really want to get by out on amp.

Rod bearings don't normally turn themselves, And normally It takes some good abuse to turn one. If its spun, it was most likely spun last year, or whenever you put it away. Make sure its not just a stuck lifter, Not sure what set-up is in your car, but if its Hydralic. It wont surprize me if its stuck. And if it is a spun bearing. As long as your not driving around in the car, pull the pan and put a set of rod bearings in. I ve seen this work many times before. Just make sure the crank and rod looks good. Hopefully it is just a lifter, and not bottom end.

today im jacking the car up and getting ready for rod bearing change to be safe But i will bleed the lifters first and see if that works before i spend any money on bearings.

I will let you guys know how this goes, i may still have a chance to get out this season if this works out.

Also yes they are hydo lifters.

ok i pulled the plugs one at a time knock was the same, to i got the thinking its a wrist pin, or a lifter but a lifter should make noise all the time not at certain rpm and load, right?

Well I'm going to try some heavy oil and add a bit of lifter additive in and see what that does if it quiets it i guess its wrist pin if it goes away was probably a lifter, but i feel better about it not blowing, at least for now because I've heard wrist pin knock can go for a long long time.

I hope this works and i see you guys out on the track.

I am just waiting on my car to be added to the base time attack list now.

Ill give the old car a fresh oil change and slap on some hood pins so my busted up fiberglass hood stays on the car haha.

well oil is changed and now i got a stuck thermostat, COME ON lol ill get this stuff all fixed some day lol, well thats a tomorrow job, good thing it happened now and not at the track at least.

also got a new battery (FOR A LAWN TRACTOR) lol meh got warrenty and its got good cca like 350 cant beat 65$ instead of 170 same size battery anyway i need a small one.

Well the car seems to be ok heat wise and so far still looking into the noise, but for now it seems good, On the other hand i made this car do be a drift car not a time attack car i just thought it would be fun this year untill i finish the car. In saying that the car has a 2way clutch lsd which seems fine at higher speed corners but the slow ones its pritty much oversteer or understeer no happy ground.

Dose anyone els have a clutch lsd in rwd car and use it at amp? should i add more friction modifier to try and get it not to be so grabby, right now its very lurchy in corners very unsmooth unless i put i foot into it and well (drift) ... hmm

Unless your diff is modified to be very aggressive, it should work fine at AMP.

hmm its pretty grabby clutches like its jumpy in turns like crazy at lower speeds, high speed i don't notice it but ill see how it works when i get out there with it i guess.

Would it have anything to do with ramp angles being too aggressive. When I was running Time Attacks in a M3 and we switched that car over to a properly built clutch LSD, the car was a dream to drive.

Jeremy, is the knock when the engine is cold and disappears when the engine warms? If it does its very likely some piston slap, which is pretty normal and nothing to worry about.

Ya I'll look into how to change LSD setup then.

As for the knock its hot or cold any gear almost all rpm accept lower idle area and is only with the very light touch of throttle, sounds metallic, yet can't be a rod sounds to light and pulling plug wires had no effect at all.
Maybe I have week valve spring or something but I'd think that would tap the valve all the time. Hmmm maybe I have a loose flywheel. It could be a lot of things still. Trying to find a good stethoscope then get a buddy to help listen. This is a pretty cf fresh rebuild too.

Rod bearings are cheap just Time to pull motor because its a pain to do in car

OK FOUND THE SOUND! worn cam follower/ clearance on shims. you can hear the noise at idle just a bit with a stereoscopic too.

Will take off valve cover and check the clearance. I will have to make custom feeler gauge to fit them. i bet the rocker will move by hand if it makes noise i should be able to figure out but it sounds like #3 or 4 area because its loud there.

if i get this fixed and bleed all the air out of rad system finally the car will be good to go.

I wouldnt worry about your diff. I know of 2 RWD racecars that have welded diffs and they dont need to drift around. Turn 2 will be the only place you might swearn at it but other then that youll be fine. What will you have on for tires?
