Man, auto tranny SUCKS. I just got my turbo installed in my auto Si with H22 swap and the torque converter keeps slipping. I made 138whp and 151ft/lb of torque at 5500rpm with 5psi boost. This is the first time a honda engine made more torque than hp. My turque curve dropped like hell after 4500rpm and my hp curve dropped off after 5500rpm. fuel cut-off is at 7200 so it's not a problem with that. THIS SUCKS. And I hear this grinding noise whenever my car is just beginning to accelerate or just beginning to decelerate or cruising at closed throttle. I can't figure out what it is. But is's robbing a lot of power in the drivetrain. Could it be the axles or the tranny? Can someone tell me what could be wrong with my car?

Anyways, I am thinking about getting a manual swap. and upgrade the axles. What is a good maker of racing axles for 4th Gens?

For the Manual tranny swap, what parts do I need. I have the following parts in mind, but can someone correct me on parts I missed or parts I don't need.

Parts
- 5 speed Transmission
- Shifter linkage assembly
- Clutch Pedal Assembly
- Manual P13 ECU <------ does the my harness fit or is re-wiring necessary?
- Some kind of master/slave cylinder? <-- tell me more details on what is it

Optional parts
- Clutch <- who has the best? ACT, CM, or Exedy?
- Flywheel <- How light should I go

 

can i ask why the hell u would even use an auto with a turbo H22 of course its going to be ****. the auto trans is not made to hold that kind of power

can you tell us something we dont know?

go to apperance and GDD forum if you just want to flame...get lost

it's properly it's the clutch in the auto tranny slipping(yes, there's is a mechanical connection there, yes a clutch)

i wouldnt even bother to find the problem if you are planning to do the 5 speed swap.

what i would do now is to disable the 4WS by pulling out the fuse, it's from some bad freeway experience with my friend with a built h22 4th gen.

act clutch would be my choice if you ask me, also you gonna need the pressure plate/clutch cover and all the throw out bearing and stuffs.

dont do lighten flywheel if you shooting for boost.

I dont konw much about gearing in lude, but i would look for a tranny with longer/taller gear, h23 vs h22's tranny.

go post in prelude forum, there's some crazy guy with boost there.

What the ****, theres no clutch in an auto tranny.

Your torque converter is slipping, you could fix it or do the swap.
