The TU2J2 is already a reasonably good flowing head - compared to many production heads of the same age & class. As such it is going to take a lot of time, & effort to get the ultimate out of the engine as a whole. Us at ebd cannot stress highly enough how important it is to have an entire concept in mind for the engine.

From inlet trumpets to fueling system & head in fact all of the way through to the exhaust system. This really directs where the modifications to the head need to be done. As such the modification of the head in this build is a one-off, designed to suit the particular throttle bodies and other components we are using. That is to say, it is not an "off-the-shelf" Head...

Update:

It seems we have generated some interest from various different websites, & forums,as such as the rallyeregister & the saxosport forums, - Which is great news, we are always happy to here from people who might have different opinions to ours! Variety is the spice of life after all! But, because of this, I would like to post a couple of reminders to this project: - it is specific to the person we are building this for, and specific to the requirements of the catgegory it is going to compete in. - it is not a complete money free-for all! So what does this really mean? - Well choices are made - such as the head & port spacing. In the Category That Graham Pickard competes in limits the Head to one that was fitted to the car as standard, i.e we can't use a later head that has the port spacing more equal, also, Graham's budget has meant that a fully steel bottom end is out of the question - Hence the bottom end mods - modifying Cast iron items instead of using of the shelf steel ones.
