I run an ally 30mm core CA18 S13 radiator in my A series 1200, works well but she still gets a little hot after 10 laps,,, think its time for an oil cooler

My attached images dont work

Link 2nd car down on the left side.

Well yesterday was her first track event, racing is Marque class which is only "75 and older full street legal cars, were 9 cars in the running, My 1200 which is totaly of era with rebuilt but otherwise stock suspension, was up against a 911 RS, Alfa 1750, Lotus Cortina, Escort Mk1, Escort Mk2 as well as a Gordini and a Dart coupe... Was very nervous hoping not to come last as the Porsche was the only other one running street tires but amazingly enough on a 2.4km very technical track I ran a 1.25 which was the fastest in the class, followed by the lotus cortina doing a 1.26 (on slicks) and the rest of the guys doing 1.30's... Wow, that datsuns handeling for a old car is just amazing, its one of the most forgiving cars ive ever had the pleasure of owning, even got the front tire off the ground in the one hard corner with only 185 kumo street tires... lots and lots of fun till the last lap where the 5sp box locked in 4th, tried for ages to unlock it but eventualy drove it home locked in 4th and dropped the box for the trans rebuilder to look at tomorrow,

To top it off, I am just stunned that stock suspensioned 1200 on street tires can actualy corner like that, best thing, after 30 laps i think it only took 2mm odd of rubber off the tires!

We only got about 10 240/260z's in South Africa, heaps of 280's though.

They dont let us run steering covers and we have to use FIA fire proof glooves which is why its such a mission to hang on to the thin wheel.

Our champ pick up (B140) comes out (well came out now that they stopped production last year) with a semi ok looking steering wheel, it just feels like $5 lucky packet quality and again doesnt suit the "era"

Hey guys,

Im running a '75 B110 1200 4 door in the Marque/Historic car racing, one of our rules for this class is that only of era mods are alowed and I am batteling to find a decent steeringwheel that will suit the car as well as a small budget, for now the big old thin steering wheel is a mission to hold onto, looking for somthing thats a bit thicker, does anyone have some pics to what the steeringwheels looked like that were used in motorsport in the 70's?

Thanks

We have huge hate here in South Africa about CA18 vs SR20 in the SX/Silvia clubs

95% of the time the people that say CA18 is the better than an SR20 is people that have never actualy owned and driven an SR20.

Easy facts:
Stock on stock the SR20 has more power and a lot more torque
modified vs modified the CA18 turns into a bottomless pit of funding due to the parts being very hard to come buy and the majority of parts needing to be changed to support decent power levels.

I have owned both in 200sx's and both were changed out for RB25's... I have also built probably 30 11 and 12 second SR and CA's by now of which all i do a 1200km break in... in my 1200 I stuck with a built A series though if i did go CA/SR it would DEFINATLY be SR due to added parts availability and more power and torque at no matter what level of modification/investment.

You are swapping a motor to make more power, why not go for the one that makes more power and is cheaper to modify as well.

Yes, its all 52mm with a small front resinator and a decent size straight threw before the rear axel

did a 15.1 this morning with the 175 tires, still changing at only 6500rpm till shes finnished break in.

I kept the chamber stock sized and im runing VERY little quench , using pump fuel with a little bit of octane booster.
