The wiki cutout below is confusing. States the 6 port Auto for 2006 is 212hp. A guy I'm buying an engine from here in a few minutes to swap in a 2nd gen says they are the same or make the same power. Why would Wiki state 232 for it's manual but 212 for the 6 port Auto?

6-speed automatic (available in the U.S. market after 2006) developing 158 kW (215 PS; 212 hp) and 159 lb·ft (216 N·m) of torque with a redline at 7,500 rpm.[2] This was the revised standard RENESIS, now with two extra intake ports like the high power version.

stop making multiple threads!

Thanks for the bump

^ hey man stop being rude and the auto does have less hp as the tranny absorbs some of it ... 212 is correct read up and youll find your info damit

the guy has like over 3000 posts, so obviously making an impact here is important to him. But ya you're right it's none of his business. Anyway, I am pretty sure the engines are not the same. One is tuned to never rev past 7,500, while the other is tuned to rev freely to 9500.

Thanks Genesis,

deleting other posts. I'll post pics when my Renesis 2nd gen swap is finished.

But basically minus the ECU and drivetrain the block itself makes the same power?

Thats all I needed to know. Assuming the answer is yes. Thanks again.

zell311@

the intake ports on the manual are different.
less airflow on auto

the manual has 3 intake ports with vfad
the auto has 2

correct me if im wrong.?

von

Oh great I already bought the long block. I could send it back still for I have not received it yet.

Can someone please confirm?

Hopefully you will get a reply from someone who knows more than me, but I think zell311@ is talking about the 4 port engine. I think the only reason the auto doesn't include the vfad is because, as it only opens at 7250rpm and the auto never gets above 7500rpm, it isn't particulary useful. As for the hp issue I think it might be as simple as the max power for the engine occurs at 8200rpm but the auto only goes to 7500rpm so:

212hp / 232hp = .91
8200rpm/7500rpm = .91

Maybe I'm wrong and that is just a coincidence, I don't really know what I'm talking about. I'd talk to your mechanic to make sure you are getting the part you need.

Correct, the single biggest reason for the drop in HP from the MT to the AT is the drop in RPM. HP is basically Torque X RPM / 5252. So you will have lower HP with a lower RPM engine developing the same Torque. You can generate the same Torque, but not for as long, so lower HP.

The AT 8 has been shown to make slightly more torque at the low end than the MT (curve is a bit higher, doesn't change peak, and I don't know how much of that is the engine and how much is the AT torque converter) Up to 7,500rpm, they are pretty much equal in 'push'. Just the MT can hold in a better gear ratio for longer, so more power.

Doing a 4port to 6port swap will probably have to include the intake and exhaust manifolds from a 6 port, as well as an ECU, but I'm far from being an expert on it.

Do you mean the 4 port auto not having the VFAD? I could swear that all the new 6port engines have VFAD, auto or not.

I was under the impression that new autos didn't have it either, but I haven't checked. Maybe somebody with a '09 auto will go out and look under the bumper and tell us.

von

Thanks again guy's. Please close the thread for I sorta made my assumptions.

I did a search on Vfad and found it negleagible for performance and not an emissions device so I don't really care for it.

From what I can tell, the difference is with the Trq converter and or RPM's. Since my project is going to have an aftermarket ECU and manual trans, any difference in manifold design, if any, should not make much difference anyways.

Thanks
