Hey guys i'm not new to the forums and have read a bunch of posts, just feel like gettign some opinions and chatting. I know that the auto tranny is weak and that it holds close to 300whp before it hits the limit. I've looked around the forums and seen a few other autos that are actually running upgraded single turbo kits and was wondering whether its worth it. Currently my car has all bolt ons besides midpipe because upgraded ecu isn't on yet. But was wondering if I should get a single turbo and just have it running on very low boost, like others do. Other then that..what can you do with an upgraded turbo on an auto..run it hard for a week before it blows the tranny?

P.S. I don't plan on doing the swap just feel like seeing what you guys feel on this subject so please don't posts a million times "You should swap the auto to manual." I'm fine with the auto and enjoy it.

Search for posts by weaklink . He had a single turbo kit and auto, I'm sure there is information there.

this is an easy one. get an ecu first.

even if you plan on running "low boost" flow rates are different between a single and twins. an ecu will allow you to extract all the potential power you are wasting with your other mods-and do so safely. if you plan on getting a single down the road, you will need the ecu anyway.

besides, i was able to blow up my auto tranny with the twins-not that you can arbitrarily assign a hp value above which the tranny will grenade.

In short, I don't think the turbo is your, um, weaklink.

keep in mind that an auto is not too quick off the line either, so keeping the twins might help coming out of the hole. I went with a small turbo-the rx6 for this reason. auto lag + big single lag=lag^2.

the good thing about an auto though is that once the boost is on, it stays on. it does really push you back into the seat and keep you there-no letting up for shifts. I remember it felt like riding a "wheelie". watch out for boost spike during shifts.

another good reason to go single is to simplify the turbo control system and prevent having to troubleshoot vac hose problems.

good luck whatever you decide.

Weird. I never thought about what it would be like to ride in an auto fd. Never have the turbos have to spool up for that split sec between shifts...Crazy.

keep the stock twins on the car . if their working the way they should the power will be great with the auto trans. save your money and install 4.33 gears in the rear end thats what makes the auto come alive. the stock trans will handle 300 to 350 HP if its serviced and in good shape, but it will not handle abuse very long. so if you hammer on it every time you turn the key it will be short lived just drive the car with respect and enjoy it. remember maintenance is the key to an FD's survival.

Thnx for the advice weaklink. How much power are you running on the FD 300+? Ya of course I know about ecu, I am waiting for an ecu before I install the mdipipe sitting in my garage. Weaklink if you had to do it over, would you stay with the single or go back to twins. Is it a good mod or is it a huge improvement?

Steve Kan told me he thought the car felt like it had about 360 to the wheels. I've never had it on a dyno.

I like the single because I used to have to troubleshoot boost problems every other week. Since having the rx6 I have had zero problems with boost. Of course it was a lot faster too.

I have swapped to a 5 speed now, but I wish I would have tried a 4.10 rear end before I swapped all the way-4.33 might be even better.

Still you need an ecu.

What about the Peter Farell PMC? Would that work with an auto FD at those power levels and still alow the hold function to be used? This is a very usefull thread for those of us with lots of FD experience but first time with an Auto tranny.

Previously I have owned a PFC and Datalogit on an R1 that got sold last year. What I want to know is why has no-one mentioned that particular ECU since it supposedly can be used on an auto? Any thoughts? Any known issues with a PFS PMC?

Sorry RuffRyder, was not trying to change the subject of the thread, but I wanted to see what ecu's are being used to get the power safely up to that level with an auto tranny. The auto tranny computer is not going to work with a PFC or Haltek or Mictrotech etc.... so what ecu are you going to get?

I really want answers to the same questions you asked. Who is running what ecu and turbo with an auto tranny, and how are they holding up to the high power?

I need to read up more on weaklink's old setup......
