rev-limiter questions

well ive been thinking about building a FB33 drift car. yea i know your thinking ahhhh another punk that wants to race around town and be dumb, NO this is gonna be a track car and nothing else. but i was looking into rev-limiters kinda like BEE*r or MSD. is there a way to get these to work on a 12a? or is it one of those things that just cant happen.

there are ways to get everything to work. but do you have the budget to really make a 12a drift? you need to be sucking a lot of power out of that to drift

Take in mind you will need two. One for leading ignition, and one for trailing.

i live near a rotary shop and the guy that owns it said he would teach me how to do stuff. so i was gonna bridgeport and street port a 12a and rebuild it. i figured that and a decent clutch and a LSD would do the trick


and thanks for the link :]

Just so you know, you either have a streetport or a bridgeport, not both (unless you have a half-bridgeport, but that's a little different).

You'll need more than just that (carb, exhaust, suspension, etc.), but I'm guessing you probably knew that already. Good luck, and post pics and vids when it's done!

its not caz of the chassis its the short wheel base...they are very ez to drift and controll long as you know how to drive.. 240's are played out and fell like pigs when they are in stock trim...

now back to the matter at hand.. like bad 83 said you will need 2 of what ever you get... if you get 2 msd diggy 6 boxes you will be set.. they have everything built into them rev limit,2 step,retard, and so on and so forth

if your motor is stock right now you can build a cheep blow thru turbo kit using stuff off a 2nd gen. it will give you the HP you need to drift as for the suspension all you need to start out with is a pan hard kit and remove your rear sway bar. as for the lsd what year is your car? if its 83.5 with the big axle then good if not you need to get 83.5-85 rear end out of a gsl or a gsl-se. then you will want to get the 3rd member out of a miata so you can have a little bigger gear 4.10 or 4.44 you are going to what the 4.44(84-85 gsl-se have 4.10 gear)

what part of NC are you from?

hp 2 drift??? how much stock hp does the AE86 have?? 112 i believe?? power is a plus and usually the more the better but im pretty sure you can drift a stock fb with suspension and lsd upgrade. with less power you would use a diff style of drifting. well anyway id go with bad 83.

im from salisbury. its like a small city a hour north of charlotte.

FB's also cost alot more to repair than a 240 or 86. im kinda new so i know ima mess something up. the FB is kinda a future thing since i can get a automatic one for 200$. and do a 12a turbo swap and everything else needed.

ill most def post progress of it when i start to build it :]

Wait wait wait...
Your going to drift an FB...
Its an auto...


Something tells me this isnt going to work. No offense, but if you are going to drift you need a stick, and if your going to drive an RX, then make it on a road track, not drift. I am not against drifting, I do it in a miata sometimes, but an RX is a track car. I guess its just me, I like feeling the rear end squat down as the tires bite.

the ae86 is not a very good drift car.. its under powered and needs lots of mods to be a contender... cartoons like initial D make that car out to be the best car ever its not even a good starting point.. a 240 is a much better starting point
but in japan an ae86 is cheep so thats what ppl used over here ppl want 2k+ for a beat up car that needs work caz of cartoons

no you dont need HP to drift and a stock rx7 can do it ez you just have to driver harder into a turn to get rid of the understeer

A lot of power what are you smoking? Ive drifted cars with less horse power then the 12a's do. old bug are about the funniest things Ive ever drifted its all about gear ratio, suspension, and skill. and enough fuel to keep the car from killing its self with a lack of fuel. i had 83 rwhp in a bug and i could drift circles around anyone that questioned that fact. i almost want to say drifting an FB would be easier then anything else due to the short wheel base long hood and the solid rear axle. as for ignition and rev limiter why whats the point. the rotaries really don't need a rev limit. they wont go past a certain point due to how the engines are most built ones just quit going at like 10,000 or slightly more but not much.

If you are serious about sliding a fb, you need to not worry about ghey rev limiters. You need not worry about building a engine. You need to buy suspension, coil-overs, camber plates, gforce strut rod bushings, and a kaaz diff w/ gears. Then worry about engines, i have yet to use a rev limiter, if the R's are to high shift! If they are to low clutch it till you get to your power range. Dont over think it. These cars drift really well when you put in the seat time! Dig up some of my old posts under "driftlanta" i have lots of info on what you need to build a 1st gen to drift.

The reason you are able to slide FBs so well is due to the amount of rear traction you are able to get. Remember if the car is loose you are not in as much control, you want grippy tires and suspension setup for traction. This way you are making the car go sideways not just along for the ride, you will also be able to spend more time on the gas. You will be able to maintain faster speeds, more smoke, and insane transtions.

Panhard is to advanced, will make learning harder, and the removing the rear sway will make it drift horrible.

I dont really know for sure, but miata diffs are torsen. If they are dont waste your money. Save up for a kaaz, buy some 4.44 gears, and moser axles. Till then run a stock diff, if you go out alot it will only last a few months so get use to replacing it. Also run some shock proof gear lube!

the bug is harder to drift then you think. even when i had more horse power in the bug the stock 7 is still easier to drift. it just doesn't rotate around as fast but still can kick it out if you wanted to. and with out independent suspension all the way around the 7 is way better for the quick whip around. tight corners are just so great in a stock seven even if you didn't have a suspension done.
