Theres a company that will build me a single turbo for my 1996 camaro z28. They told me it makes about 415 hp (crank). So im guessing 375 rwhp? will my Auto trans take it.?


Thanks,

The transmission should be able to handle that kind of power unless you are going around doing jack rabbit starts all the time. But why bother with all the hassle of a turbo if that is all the power you want. You can get that kind of power normally aspirated and still have good street manners.

 

I did a stock rebuild on the tranny and after bolts ons, tune and 1.6 rr's, junior found a way to grenade the tranny. It now has a street/strip rebuild and works great and junior hasn't been able to break it.

So, the question is how will you behave with the extra TORQUE because it's not the top end HP that breaks the trannies.

As for the turbo, why not do a search on this forum? But, I will now be facetious

absolutely go for a turbo setup on your 15 year old engine (has it ever been rebuilt?) and enjoy the ease and simplicity in plumbing for it.

 

Its not if it will take it as much as it is how long will it take it.

Great quote from the automatic transmission teacher. "The candle that burns twice as bright burns half as long." So we need to figure out how bright the customer wants to burn so we can build a long enough candle.

If your not sure how much of your trans has left there is no way to be sure how long it will last. But you will be burning brighter.

Think hard about what pete said. Turbos are very hard on cars. I would never put a turbo on a tired motor. Bare min I would do is upgrade the head gaskets add a oil and trans cooler and upgrade the radiator and fans. Turbo generate a lot of heat.

For what that kit will cost you could put in a new 383 that is just as fast and a lot more dependable. But for 400HP even the 383 is overkill. Leave the turbos for the guys that want 600+ HP.

 

4l60e is rated at 350 hp and 300 ft lbs torque. anything over that increases the chance of failure by an unknown factor. meaning it could last a couple yrs or a couple hours.

 

Thanks, where did you find those specs? What is the recommended tranny upgrade path beyond those specs?

 

servo, input shaft and drum, hardened shell, upgrade valve body. may also be a good idea to upgrade the power gears to five.

 

^ Are you saying go from 4 to 5 speed for the auto?

 

Craby, are you sure all 4l60e are rated that high. Back then I used to rebuild the 700r4's you could not make statment like that. A 700r4 for a 2.8 might have 5 clutchs in a clutch pack but one that came with a 350 might have 7 clutchs. The 2.8 may have had only 2 plantary gears in in a gear set but the 350 would have 4. GM did this to save a few bucks on the v6 tranny. So are you saving they do not do that now? I have asked the question here a few time and no one has given me an answer.

Edit: I just checked the parts manual for the 93 . The are a lot of internal parts list as L32-M08 and Lt1-M08. I will take that to mean there is a V6 and a V8 4l60 anyways.

 

stock 4l60e has 4 pinion gears in the planet gear set, the 4l65e has 5 which is part of why it can handle up to 400 hp, i think they (4L60E&4L65E) have 6 and 7 clutch plates at least thats how i remember it. as far as i know the 4l60e s are all the same, im not seeing parts for any other, and thats not rwhp. im still looking for the write up, found it when i was researching for my trany over a yr ago.
