Welcome T3 kid
by the way you have posted in the wrong place but never mind.
There is a big world of motors
stock
mild 1776
wild 2110+
then there is the world of turbo
Type 4 conversions for LOTS of torque.
It is not a simple answer.
The first question is "How much do i want to spend?"
Is it a "daily driver or a weekend warrior"
To get some idea you need to read a few books to understand what is available,
A simple understanding is available at
www.aircooled.net and go to the tech sections, There are some good simple areas of what is available.
Another good area is ww.shoptalkforums.com and there is a link to Tom Notch's section. He has a great T3 site with a huge T4 motor
But you need to pick 2 of the following - and only 2
fast
reliable
cheap
