![Question](https://ls1tech.com/forums/images/icons/icon5.gif)
I`ve decided that i`m going to rebuild the log on my TTi kit and was wondering if It would be better to run a 2-3/4in or 3in log I`ve already measured and clearanced everything and it will fit. But it`ll be a little harder to change the plugs and I have to used 90* sparkplug boots. I was thinking about tucking the turbo up under where the alternator bolted in from the factory but figured that would heat the block to much. So i decided to stick with the log and just make it bigger. ![Grin](https://ls1tech.com/forums/images/smilies/LS1Tech/gr_grin.gif)
Also has anybody removed the abs pump and converted it over to straight power brakes? is it as easy as removing the pump erasing the codes and installing a proportioning valve or is there more to it?

Why are you going to change it? You planning on making over 900rwhp?
The 2 1/2" log is more than sufficient. The 2 1/2 will give you greater exhaust velocity than the 3", without hurting performance. The only way I would go 3", is if I was planning on making over 1000rwhp. But that's just me.

Hey rob. The only reason i was going to do the log is because the turbo tech kit comes with a 2 or 2-1/4 inch log don`t remember for sure. But i figured even a stock motor could gain HP from a larger log even if I only go to a 2-1/2in log. What do you think? But I do know that my log is smaller then 2-1/2. So could i benifit from the larger log or do you think the 2inch is suficent?

I just went out and double cheaked myself with a micrometer and yes it is definatly 2inch. So in your opinion should I go 2-1/2 or 2-3/4in. the way i think is i`m redoing the log anyway so might as well make it the way it`ll be most efficent and make the most power. Thanks.

MYturboT/A can you keep me/us updated on how much that is gonna run for the upgrade as I am curious about the same thing. If you do this yourself, when your done could you give a gustimate of how much it would run. Thanks.
