10th AE. I wanna make it faster.
 

I already put an exhaust on it. 3" turbo back. Light flywheel, stage 3 clutch. heavy dut pressure plate. short shifter. What are some other things i could do to an s4 motor? and, who has info on a 3 rotor engine. all info like tranny and mounts would be great info. thanks guys

well after you blow it up ( you do know the s4's boost spike with anything other than a stock exhaust right )

i would suggest a bnr stage 1 and a stand alone and a boost controller. there you have it. 280 whp.

Sure, larger turbo, injectors, fuel pump, aftermarket ECU, SS fuel lines, tuning, new IC, and a whole bunch of money.

20b will be even more expensive.

Any TurboII will suffer from boost creep unless their stock wastegate has been ported.

Just get it towed behind a FAST tow truck after you pop the seals.:lol2:

Keep your foot out of it or you will blow this engine.:shocking:

Seriously, you need to focus on what are called reliability mods:
1) port the wastegate
2) install a FCD
3) Get something to control your fuel, SAFC minimum.
4) Get tuned

If you don't, you are looking at creating a lean condition that leads to detonation which leads to a very expensive rebuild, or another 10AE that is ripe for a trip to the Dark Side...

Good luck and remember you heard it here first.

Wow

ok, 3 rotor swaps are a bit pricey but doable. here is a break down of the costs.

not included in those prices are a rebuild for the engine. you will probably want to do this.

10th AE guy again
 

Where can i get this tuned? I forgot to say I have a fcd. If i get a bigger turbo like a "disco potato" should I get the wastegate ported? and where can I do that. Where could i get my stock wastegate ported? A little more help would be great guys. Thanks

Do you have fuel management? No? Well, you can't get it tuned then. Buy yourself at the minimum an Rtek7, or move on to a standalone if you want that flexability.

Have you tried using the search feature for anything you're asking about?
Every possible thing you would wanna know about RX-7's has been covered here at least a hundred times.

You need to take about 20 steps back and go to the top of the 2nd gen forum and read all about your car..and what mods to do safely to get the power you want to. Also....search...search..search...and last... a "disco potato" is too small

Want to make it faster? Sell it to me.

First of all, the "Disco Potato" aka GT28RS is probably the size of the stock turbo. It's not a viable turbo upgrade for this car.

here's a suggestion.

remove stock turbo. port it yourself (there are writeups) or take it to a machine shop. at the same time replace and possibly simplify vacuum lines. You have a FCD. Good. Now I'd recommend at least an SAFC like has been said (like $100 used) or even better, go straight for an Rtek 2.0 (pocketlogger.com) .

Get some 720cc secondary injectors while you have the car apart. Also clean all your stock grounds and add a ground at the ECU (do a search). Upgrade your fuel pump and rewire it (do a search). Do a bigger turbo inlet duct and of course have the exhaust. either spray the intercooler or replace it with a front mount, depending on what kit you get and whether you are willing to remove air conditioning.

Tuning an SAFC is really easy if you have a wideband or if you take it to the dyno.

NOOOOOOOOOOOOOOOOOOOOOOOOOOOOSSSSSSSSSSSSSSSSSSSSS SSSSSS!

^^^not original stock?

i dont get it[/sarcasm]

Click the link on RETeds Sig two posts up. He has a great section on how to do a "staged upgrade"

Well holy dogshit, another clueless newbie who wants to make their car "faster"....

do we really need short shifter, what if you can shift really fast and good?

Only if you want to...MaD ShIfT QuIk Y0!

Help me understand better but wouldn't a lean condition cause pre-ignition or does this only happen when higher in the rpms since there is less time for detonation?

I don't entirely understand your question.
