Red face How much power will OEM tranny hold?

What is the transmission going to hold power wise, I am fully built and turbo, i don't want to disintegrate the transmission on the first run, What are my options. Also anything else you guys can think of please help me. Pick in signature of the turbo and manifold if interested.

If you want people to read your post, you should make your title more descriptive. We have HUNDREDS of threads in the archives entitled with some variation of "HELP". It doesn't mean much.

(I'll change it for you this time.)

I have a fully built turbo motor. I am making 368ft/lbs of torque and 400 hp @11psi. My tranny is just fine but I wouldn't dare launch it hard I have a stock rear end.

Tell me that torque number is a typo. 368 ft lbs of torque is way beyond this 4 cylinder engine at 400 hp. How about 268 ft lbs?

Given that its a turbo motor, I'd believe it. Centrifugal blowers are the ones where the torque numbers usually lag hopelessly behind peak hp numbers.

Gotta be a typo, or a mistake. CJB's last dyno sheet made 559hp, 326ft/lbs.

368ft/lbs is way high for that HP#.


As far as the trans goes, Drive it like you can break it at any moment. Then look into dropping 10K on converting it to a dog-box.

That is very high numbers...At around 400hp at the wheels around 290ftlbs seems right for the S.

completely off topic but...your manifold seems to have a heavy brace attached to the bolts on the head. Have you taken into consideration the extreme thermal expansion stainless steel experiences or do you feel that it wont be a problem? Have you already driven the car around? If so how many miles so far?
I personally am trying to figure out how to brace the turbo itself better and I was thinking of making something with a swivel design that will let it rotate and move as much as it needs to. The only problem is that it's complicated and expensive.

Now, back to an on topic post. From what I've read in the past about a year ago was that at about 400-450rwhp, the 2nd gear's heli teeth sheer off completely. That's about as much I've ever heard about gearbox troubles. The 2nd gear.

Not a typo it is the turbo. I have a 50 trim Stage 3 wheel .63 a/r It spools at about 2800rpm. Those are real numbers trust me I was shocked and didn't believe it. My motor isn't even a honda motor anymore. Take into consideration compression being sleeved and such it is a different machine. It is closer to a DSM now with honda symbols. The torque and hp should be close on my motor cause of the setup.

Then with those #,s your car would have no traction and go into a serious wheel spin..
