Wanting to go Megasquirt

[Ford Fester]

toyota 1zz or 2zz cops are awesome... lots of spark and easy to come buy... i got my 1zz ones out of a 01 corolla and they have igniters built in so you can wire them right to the ecu ignition outputs... and they look sweeeeeeet

more info on this^^^^^you just directly wire them to the ecm??!?!?

Okay so Im eyeballing a set of Celica COPs on ebay... I might nab them if the price stays low.

What do I need as far as crank or cam sensor?

Also I think Im gonna go with a non-pnp megasquirt, with a diy harness. That way I can use it on things other than the festy, if it ever comes to that. Should also help keep things neat.

Celica COPs on the way...$55 shipped...gotta find pigtails though.

What sort of injectors should I look for?

[Nerd Racing]

550's from an RX7, high impedance.

[Rocketman]

DSM 450's or RX7 550's

[bhazard]

Can't find much high impedance stuff, lots of low impedance though...

Doesnt matter with MS. You can wire a high or low Z driver

These fine then?

if you want to do it right the first time id recommend using ev14 injectors. as im finding out now ev1(stock style injectors) are very laggy and inconsistent causing all sorts of crappy idle and low rpm drivability conditions. my 680cc denso's only operate at 10-15% lower duty cycle as my rx7 460cc's to achieve the same afr's due to multipule spray "jets" instead of one big smooth cone pattern. my frined that has been boosting miatas for a while actually yelled at me for getting them.

im getting the 1000cc ev14s :

the 1000's seem big but with the ev14's incredibly fast cycling time and excellent spray pattern you can run them at much lower duty cycles without issue. hope this helps... much cheaper to buy quality big injectors now than to have to spend more later to get another set when you want more power later.


edit:
join miataturbo.net if you have not already and troll all of their megasquirt write ups and builds. also make an introduction thread telling about your car and your plans for it with a little back ground on yourself. if you dont make an intro thread or if you ask questions without searching they will be brutal and offer no assistance.

i think i paid 50$ for my 550cc rx7 injectors. however, those 1000cc's arent a bad price, ill have to probably end up saving that site and ordering some up when taxes come in

I am pretty sure ^^^ those are what i am going to go with as well, that way you have plenty of room to change you whp.

ya i think im getting some 850cc ev14's when the festiva is gonna be put back together.... i dont know when thats gonna be but ya, get some good injectors, its well worth it....

[nitrofarm]

This is some good imnfo

Saving this thread,Good info for us Turbo Newbies drool

Im just gonna keep it cheap and go with the RX7 injectors for the moment, I can upgrade later.

So what do I need to trigger the coils?

[IdealSociety]

you can either upgrade the MS unit to have a coil driver built-in or you can use an external ignitor that MS can operate to give the coils the voltage they need. DSM and VW ignitors are commonly used and cheap to get if you dont run COP's with them already built-in.
