Daily driving and drifting definately don't go together! T2 tranny, upgraded clutch, drive shaft (eventually a rearend if you beat it up) modified engine mounts Upgraded cooling (water/ oil/ air) Exhaust, manifolds, turbo coils, Stand alone ecu, wiring Fuel pump suspension, tires, roll cage (if you want to drift seriously) lots of insurance and a company that wont inspect your car! But what a fun motor! |
what youll need is a very large wallet, and that pretty much sums up any 20b conversion for ya

Yhea i know....I got my self into it so i know i have to expend the money , and with a lot of work i save and i will have this beast on the road hopefully very soon...(4 or 6 months) lol .....
Whats the best brand of ecu for this set up?? And What lsd should i use??? |

I just cut and pasted this into the other thread, I might as well go back and give you the same paste:
EFI / Stand-alone ECUs Now for the controversial part... There are a number of stand-alone ECU systems out there that can fire and control a 20B 3-rotor engine. Mazda went with an independent trailing split to decrease emissions. With that said and done, let us analyze out options. If you do use the stock ECU, at minimum you're required to use the stock Cosmo 20B coil packs, which are not very easy to find. On "front cuts", they should be intact, but most imported 20B's do not have them. The Cosmo 20B coil packs are normally mounted on the fender area, so they are not usually included with just the 20B long block.

THANK YOU Sooo much this will help me a lot on my proyect.

Made any progress or decisions?

sorry i just grazed over this thread, sorry if it was mentioned already, but MegaSquirt could be an option. it might be one of the more difficult alternatives to get up and running, but with the V3 board you have a "proto" area for adding little extras like boost control, water injection, and anything else you can work the support circuitry out for. i can't endorse MegaSquirt 100%, becasue we have yet to get our 13b idling, but it should be going down this weekend. i'll post anything interesting that comes up with respect to megasquirt to keep you filled in. additionally, if you go with megasquirt, i may be able to sendd you our calibration files. i actually don't think you would have to do a whole lot of editing to them becasue of the extra rotor...just change a few parameters...i could be a little off on that one too though.
180sx20BDream: I PMed you... |
^ if you want some more info on mega squirt i suggest you go look on ausrotary.com under the tech section there is a huge thread on mega squirt...worth a read
