wanted to no what people thought of black engine bays i was thinking black with the 2 yellow strips on the engine but with chrome parts the out side of the car will be like a monaro yellow

Posted

I had a black engine bay on my first rolla. Biggest mistake ever. Everything blends into each other and oil leaks are a prick to find. Besides that, it just looks so cheap and lazy.

man its getting costly things i need to get for xmas break are

 

 Holley red fuel pump

 Gilmer belt drive kit (chrome or billet alloy for a 12a rotary)

 Auto meter gauges oil, fuel and water temp

 Weber and manifold 48doce for a 12a rotary

 Oil cooler for a 12a rotary

 Billet alloy or chrome oil catch can and radiator over flow

 Billet alloy or chrome alternator

 

I just picked up a new holley red fuel pump and red fuel pressure regulator off ebay for $270. don't know if that is cheap, but i'm too lazy to shop around.

The Gilmer and weber/manifold pop up on Ausrotary all the time.

 

I got all my Autometer Gauges off ebay from USA which was a fraction of the cost compared to what major parts outlets here charge.

 

 

What radiator are you using? I'm having overheating issues which i'm trying to diagnose, and am holding off on buying a PWR Radiator if i don't have to.

yea just the one of the rx7 its in good nic but we will see.

 

what did you use in the way of the oil cooler could i use a trans cooler or is engine oil too thick i can't get a hold of a rotary one for cheap

should be able to pick up a S1/2 RX7 oil cooler fairly cheap. I got one in good condition for $50, thats what i run in my car without any issues

 

Also I'm using a V8 Torana radiator in my car

I'm running a 3 row S1 RX7 Radiator which cools fine at idle, but can jump 10-15deg whilst cruising on the freeway.

 

I'm currently using a S3 RX7 oil cooler that bolts to the block, and has water lines plumbed into it.

 

I do have a PWR oil cooler up front but i found it took a few seconds to get oil pressure up. Might have something to do with the time it takes to pressurise up the oil lines and cooler before it feeds the engine. Mine set me back about $300. Look on ausrotary, they pop up all the time.

I couldnt really find a neat place to fit a standard S1-2 oil cooler. It was just physically too long/wide to fit up front without chopping the car up.

 

An auto transmission cooler is not an option.

My PWR Oil Cooler

yea i might get a engine mounted one are they just as good ? and what did you guys do as far as the emissons bull shit i want to pull it all of like i did on the 4k

 

I wouldnt recommend them. Its was kind of a stop gap solution to get mine engineered, as i wasnt happy with it taking ~5secs to get pressure up.

 

They are not the most efficient at cooling the oil as they are directly related to the hot water passing through it. Which in my case with the car running hot, means the oil runs even hotter.

 

As for emmissons testing. I ran the standard Nikki carb, in conjunction with an air pump. I had to get a 20mm diam metal tube welded into my exhaust which allowed the air pump to inject fresh air into the exhaust.

I also used E85 Fuel (same as the V8 Supercars). Its claimed to burn cleaner and put out less HC ppm. To run E85, you will have to take the jets out of the side of the fuel bowls and drill them out to 1mm, as you need 1/3 more fuel for the car to run properly.

 

With the weber bolted on, my first emmission test was >1000HC ppm. With the above mentioned setup, it pulled 250HC ppm. The limit was 500ppm so i breezed it in.

My system had 2" extractor pipes into a single 2.5" pipe with 1 hotdog, 1 resonator and 1 turbo muffler. It just scraped through the noise test.

I have since replaced the rear muffler with a Rotaflow muffler which improved flow but left the noise roughly the same.

 

If your going to put new mufflers on, I can recommend Rotaflow. Having said that, the best exhaust setup is generally 2" extractor pipes, into twin 2" pipes through twin resonators and coupled into a single 2.5" pipe over the diff into a rear muffler.

 

What gearbox are you using again? I recall it was a S5T? I'm keen to see where the shifter is located if you havent shortened the extension housing. I shortened mine, which in hindsight was probably not really needed.

Couldnt agree more!!!

 

On my NA RX7 i ran racing beat extractors, into twin 2in pipes with a rotaflo resi in each, into a 2.5 pipe over the diff and into a rotaflo muffler.

 

BEST exhaust system for an NA car, this is pretty much what the IPRA boys run with the big port race motors. Only difference being the amount of mufflers

 

Some people say 3inch at the back but IMO thats too big and only results in more noise without any preformance gain

 

This set-up on my car way loud when you had your foot down but just cruising around was more than respectable and not too drony
