I'm trying to get more performance out of my 83 300sd. Notice I said performance and not horsepower. Increasing horsepower is great, but not at a loss of low end grunt. My main focus is Improving acceleration. I am happy with the performance above 40 mph, but getting to 40mph usually a time consuming task.

The biggest problem is my tranny starts in 2nd gear. Is there a cheap and easy way to get the tranny to start in 1st? ( without me shifting myself. ) I have heard about the valve body swap, but finding that 1st gear start valve body is like looking for a needle in a haystack.

Eliminating Lag , Quicker Spool is what I was mainly thinking. I was thinking a boost controller could help with spool up, what are your thoughts on this? and then a newer, modern turbo, that spools up much quicker, not necessarily bigger, just newer technology. I have been looking into the Holset turbos, the smaller ones, no bigger than the hx30.

Please disucuss..
