SIR E30

Awesome!!! That rear subframe looks so good with fresh bushings and powdercoat. Great work man, doing it properly!

I sold it for $7500 a few years ago, with no cert but current wof and reg and rolling on factory steel rims if that helps give you some idea of what its worth. edit: it was mint then, clearly it has deteriorated. The roof was fairly new when I owned it and was mint when I sold it. Oh how I would love to get it back and out there on the road..

Thats good to know, cheers mate. Kudos again for a super tidy E30

If only this wasnt in christchurch.. damn Im tempted!

Looks awesome! Would love to do the insulation job on mine one day. Can I ask what the deal is with the 7 series master cyl?

Sorry, sold - I thought I had another but I cant seem to find it

Yep still available, just let me know

I have an ECU, does it matter what it is?

B

I have one if you get stuck

I can relate to this, a great feeling!

I've been dying to have the torque discussion with somebody. Rotarys deliver their torque much differently to a piston engine. Torque is purely "rotational force" where as power is torque multiplied by RPM. A rotary doesnt have as much "peak torque" as an equivalent piston engine nor does it deliver peak torque as early, but typically has a flatter, broader curve. The more area under the line on the dyno graph, the better. The age old "V8s have lots of torque" is a good one, the V8 simply delivers torque earlier and drops off earlier, so a V8 can have low power (torque with a low RPM multiplier) this will still shred tyres, but it wont pull and pull and pull! The rotarys ability to rev combined with a flat torque curve is an awesome experience! Simply put, the terms "torque" and "power" only tell part of a story, to get the full picture you must know where in the rev range the torque is produced. So my desire for a 4.1:1 is purely to match the RX7 gearbox and to compliment the 13b's love of rpms. That said, I didnt chose the rotary for my car based on torque or power alone. I dont dislike V8s or big sixes (my other car is a big six). I chose it for the wide power band, the weight, the size and of course the sound and smell! I can pickup the 13b fully dressed with turbo and manifolds, attached to the gearbox and lift from the engine end off the ground. I cant do that with an M20/M50 engine on its own... Thats ALOT of front end weight saved. Dont take this like I'm saying rotaries are the best choice, I'm still open minded to all swaps, but for my application its going to be a sh*t load of fun! After all, thats why we do what we do isnt it? This car of mine should, depending on when it comes on boost, deliver peak torque at around 4k rpm and keep it relatively steady all the way to 8000rpm, leading to almost 200kw at the rear wheels in stock trim without porting. Tell me that wont be fun in an E30??

Try 20k. at least - all worth it though LS1 is light, lighter than an RB or whatever other weird fitting engine you could come up with M62 is a great idea for keeping it inhouse, if you dont give a rats about the badge go LS1 - skinnier heads (not twin cam) means a bit more room around the place for brakes etc. Have seen M6X in E30 bays and they're tight. Like, TIGHT. Whatever you do, a lightweight V8 in an E30 is going to be a bucketload of fun! I wish you luck and most of all an enjoyable project

Following. around 4:1 somewhere would be good if theres one around?

No sorry

JTP the 02 sensor is 4 pin.. I dont know what this means to you, but maybe Ive stumbled across a rare and strange part...

02 sensor is from facelift 320i if that helps. I will check the pins when I get home tonight

6 cylinder Coding plug $30 (tacho signal conversion for M50/M20 conversion in 318i) Airflow meter and airbox $50 Coolant overflow $20 Motronic ECU $50 Auto gearbox crossmember $20 ICV $40 intake boot crackfree $30 ignition coil and bracket $20 02 Sensor $15 All prices include shipping. If you actually need any of this stuff and I'm way off on pricing feel free to lowball the sh*t out of me.. just need this stuff gone.

NZKW i think.. but $350

Are the 325i calipers any different to 320i units? Also, do you have 325i axles?

Hi all, In the market for some front seats of a sportier variety than standard - maybe some recaros. Something that will pass cert. Fishnets would be amazing.. If the seat needs rails then preferably they will come with them. Let me know if you have anything kicking around. For a coupe, but I dont really care if the back isnt accessible. Cheers, Jason

Economy gauge gon' be sitting on the redline haha.. So long as the fuel level works. I got a coding plug off Kerry tonight, see what happens when Im back at home on saturday!

All correct, the leading plug fires at 5atdc and the trailing fires just after at 15-20atdc. I reckon the 4cyl plug sounds good - just hope it doesnt mess with the fuel gauge. As do i, they are great fun - especially in a cool chassis such as an E30! Mine is a standard port series 5 turbo, no major mods just front mount and exhaust with all unnecessary things deleted. Hoping for a nice safe tune and just see what happens.. Nothing beats the sound and smell though! Itll upset a few people on here but at the end of the day its my car - will post a build thread once its done. cheers for your input Troy and Westy

Pretty sure it was reading 700 when the computer said 1200.. and i guess it would get exponentially worse as revs increase, but I dont know as it hasnt been on the dyno yet. Sorry to be dense, but could you explain "coding plug" to me?? Edit: Google answered my questions. Are these easy to acquire?? Will it affect the fuel gauge as some threads suggest..?

According to this it fires twice http://www.racingbeat.com/mazda/performance/rotary-tech-tips/tachometer-plugs.html as for high or low, I cant remember - but going on the dyno next week hopefully so will be able to check it out. Yea now that I know more I do slightly regret the microtech ECU - but it works for now, and Im not doing the wiring again if I can avoid it. Will upgrade one day if I actually like owning a rotary :S Check the link above.. I know its talking about getting the signal from the coils/distributor instead of the ECU - but it does reinforce that the firing pattern is similar to 4 cyl. Bearing in mind that for one rotor revolution the eccentric shaft (crank) turns three times..
