Hello Friends,
Todd.K built a 3.8l engine for my 996 GT2.

looking good bro! this setup will certainly kick some ***! i bet you see 800hp pump and 900+hp with race fuel!

 

Congrats man! Looks killer.

Thank you Guys,i will run it on my A30/76 on more boost,if not satisfied will go with GT30/86hta .

 

You're gonna have fun with that! Enjoy!

 

You can never go wrong with Protomotive!
Congrats
Robert

 

I see 3.6 motors making just as much power if not more .... So other then the cool factor is there any other reason to do a 3.8?

 

I can't grasp why you would do it either unless you already need new pistons and liners. Then hopefully the pistons and liners are better than stock, which is not often the case.

 

In most cases,,a larger engine will have better throttle response and more power off boost And IF IT CAN get feed enough it will make more power on the same boost levels..

 

That is a good question. I know Tim posted that the 3.6L lasts longer hours wise than the 3.8 and 4.0 options. OP do you know if the pistons are CP or something equivalent. I don't know much about the protomotive builds though.

 

I don't know about making more power at the same amount of boost

 

On the average, 3.8 will make 5% more power at the same boost level then a 3.6. Also you should be able to build a 3.8 L for the same price as building a 3.6 motor. I think if you're going to tear into the motor this is a cheap place to make more power. Remember that I am from Texas, our state motto is bigger is better!

i asked layinback this exact question when he did his... 40 more rwhp and better off boost response. nice upsides. 5000$ in parts plus labor big downside!! for my limited budget i couldn't see the hp vs dollar
