Just SA, Vic had restrictions way before SA.

 

 

Sorry for the Hijack Haydoss, Sweet ride man, loving your work.

Haha no worries :)

 

Recorded my exhaust last night, thought it sounded somewhat like a rotary (well thats what the kids at school tell me), don't really know why walked to the front of the car haha.

Seems to be running extremely rich and using more fuel, i think its from the cold weather and the carby not heating up properly. When my dad gets back from holiday, we will try and build a "Carby Heater" so to speak haha. The plan is to put hoses from the heater and get them to blow out on the carby heating it up, not too sure if my dad was planning on enclosing it lol. After that, going to adjust the air/fuel ratio maybe a rejet? of the carby and then chuck it on the dyno.

 

I'd like to get about 100rwkw, is that too much? how much do other people make with a supercharged 5k?

Cheers :)

Weld up a small resivour that runs goes around the intake piping. Inlet and outlet for heater lines. Works the same as an exhaust 'hotbox' and exactly the same as the setup used on 3K-B manifolds.

 

Heat helps the fuel vapourise better giving a better burn.

 

Run a heater tap off a KE70 or something so it gives you the oppertunity to turn the "intake heater" on and off.

how many psi and rwkw have you achieved so far with the stock motor and cooling system? what are your inlet temperatures like without a cooler and that roots heater? you might find that if you go any further you will end up spending a packet on the next development. speaking from experience. good effort :)

Due to the cold weather, i haven't been driving it lately because the carby is just toooo cold! always have to run with the choke out and is very thirsty on fuel. Once the weather warmed up a bit, we headed down to u-pull-it and got a ke55 heater core. After relocating the battery to the other side of the engine bay, we mounted the heater core infront of the carby so it heats up. There has definately been an improvement as i don't need the choke out while driving now, but the carby still is a bit cold. Made a quick video of a walk around incase anyone was interested :)

Not sure what i want to do with this car yet, finishing high school and not have a job limit the amount of money spent on it :(

..and the big question is....

 

How do you know if its running lean or rich when you're driving it??

 

Have you had it on a dyno to check mixture while under load? or tried a fuel mixture meter with a oxy sensor??

 

Unless you can find out how rich it actually is when driving, the needle might be miles too small and it will chew juice like there's no tomorrow, or it might be miles too big and it will run lean & need a choke to make it go.

 

$50 on a dyno run would tell you a lot, and once you know where it is rich and where lean you can easily get a needle to make it right. If the needle is too big & it is running lean you just sand it down. If not, buy a leaner needle and adjust it.

 

A dyno man would check the timing over the rev range too, making sure there is no detonation. What fuel are you using?

 

It snows in Orange and I've never worried about heating the SUs. 3/4 to full choke for 10seconds in the garage, then half-choke down the road for a minute.

 

When its running properly it should be about 25% up on a stock 5K, judging from the handicaps they use in motor racing.

Thanks for the info Altezza :)

Yeh getting bored of it, never really get to drive it cos its always at my dads house being tinkered with. At the end of the year i was planning to get another 180sx so instead of spending more money on this and probably not getting it back, id rather sell it and have the money available so when a cheap one comes up for sale i'll be able to buy it.

 

Haven't really got much interest in it, thinking of painting the pannels that aren't painted and put 3 months rego on it, then lower the price a little. Not fussed if it doesn't go, but i'd rather someone enjoy it more then what i have cos it never gets driven :(

Ended up paying rego for it so ill be keeping it for the time being.

I got some work for the holidays so i got some money which will be spent on it! Hopefully on the cards is HSD coilover kit, XT130 LCA's and hopefully suspension setup aswell/brakes and reset leaf springs. Dad said he would pay for a bit of that, so with the left over money and my other savings, i plan to buy some new rims. Honestly don't know what to look at, but i want it to be different. I was thinking widened steelies but for the price I'm paying, there isn't much point getting them widened to 7" 0 offset. I was interested in sunraysias and found a supplier for 4 stud (unsure of PCD) but once again, 15x7 -12 will be too much work for my guards and i don't want to screw them up haha. So i'm assuming i'll be looking for 14x7 -0 or 15x7 -0 but doesn't bother me. Looking on ebay, i've seen some Work Equip 03 knockoffs (15x8 +25) from 'OG' brand, for about 800? i think, probably will need a lot of guard work being 8" wide. Just trying to find what suits my car and my taste i guess.. suggestions appreciated!

Stay tuned!
