20B N/A build thread -- 3rd rotors a charm

3) Cost, im saving almost a grand on the entire thing, I figure I could use the money elsewhere for the car rather than a ECU when the Haltech is just as capable in completing a job.

I also recieved my exhaust manifold flange and lower intake manifold flange from To_slow, great products!

Ill post pictures of the flanges if anyone is interested.

Bear in mind with an Electromotive regarding the cost:

You're getting a superior trigger system with the ECU
You're also getting coils that will never need to be boosted by a CDI. The single tower coils in my car will light 9.00AFR + 375cc of water without blinking an eye.

So if plans are to spend the ECU savings on an ignition, you may want to re-consider.

Just a thought. Obviously they all work well, but the points above were things I never thought about, so just passing it along

My thoughts on the clearance issue:

I had a half bridge engine I ran back in the day witha T04-R. I blew it up and when we tore it down I found the front rotor had ALL of its corner seals on the gear side of the rotor jammed in place. There were scrape marks (still have the rotor if someone wants pics) along the tips of the rotor. I didnot build this engine so I can't comment on the care that was taken with regards to setting proper clearance in the first place (basically whether the housing was undersized for the rotor or not) but I can absolutely tell you my rotors contacted the irons at the tips, and the engine was NEVER over reved. In fact it never even saw stock redline.

I'm no expert though
