Hi guys, I really need some help deciding on a build for a t4.
So first, I have a t4 case and heads. Need to have a ton of machine work done. I have a few guys here in town that do a pretty good job. This will be going into a much lightened baja that I want to race. There are still a ton of mods that need to be done to the car, but it is a work in progress. I would guess the car is somewhere south of 1500lbs with no motor or driver. Since there is no back end on it, my options are seemingly limitless on the combo's I could use. The three rib tranny in it has been "reworked" but no idea what that really means. I know the three rib is not the best option, a rancho trans may be in the works in a few years.
Ok, so if I go with 105mm jugs and some kind of crank. I was thinking about a 90mm, but someone else suggested an 80mm due to how hard it could be to clearance the case for a 90mm.
No idea what cam to use.
No idea what c/r should be, been reading on the forums here and am more confused than ever...Should I use super squish pistons?
I plan on running the motor between 3k and 6k rpm. I figure that with that much displacement I shouldn't have to spin the motor stupid fast, which will in turn, at least in theory make all the parts live longer.
My big question at the moment is what type of tin and fan to use? Fat Max? Stock? Upright conversion? I am sure there are pro's and con's to each, looking for strictly racing gear.
Also, what gear ratios and r&p?
Hope to Turbo it, been reading here about that too, also more confused than ever. I do have a pretty good idea of what parts I need on that set up.
Basically, I am looking for some idea of a parts list, I am curious about what you are running and what it cost to build just for the parts. I know t4's are more expensive than t1's, but the Physics I studied tells me that a bigger engine will be more capable of high hp due to the sheer size of the thing.
I am learning all I can about these engines and have a couple t1 builds in the works. I can also be found on thesamba with the same user name.
