Turbo 4age tercel

Post by SirFoxx »

I'm just posting this for now as a teaser. Still have a lot of work to do, and I'm not great at documenting my work. I've had a few people inquire about it so here are a few pictures.

Very interesting project. It will be very quick since that chassis does not weigh much.

I see also that you have manufactured exhaust manifold for that. Do you need to modify fuel tank and lines for that modification? I have understood that 4AGE has fuel pump inside tank normally.

The exhaust is a diy job. There's a fellow that makes them for mr2's since they suffer similar space constraints. I wish the flange was angled a bit lower, but I'll take what I can get.

As for the fuel pump, depends. I have a 7age that runs off 60psi using an external pump and the original 5/16(?) steel line coming out of the sending unit, which then feeds 3/8" rubber to the tbi unit.

The turbo 4age is going to use a similar setup, but I have modified the sending unit to have 3/8" steel lines so there isn't a bottle neck in the fuel system.

If you 4age swap your t4wd, you can use an ae86 gts tank. It's the same, but it's setup for an in tank pump. However, you'll need to source the hangar and the fuel level unit.

Few more pics. Got the intercooler and radiator mounted. The pics don't show it well, but it's going to be a huge pain to make the piping and upper radiator line. I still need to figure out where to put the blow off valve as well.

The fan is a cheapo one my roommate had laying around. I'll probably want to run two of them, especially since my roommate wants to add a/c to the car once it's running.

And yes, the grill still fits with no issues :)

Nice work Keegan,

What purpose is the stock radiator going to serve? I see you’re working around it, but understand the large AL radiator will cool the engine? Piping/hoses will be interesting. Do you expect this set up to have some of the same “heat” challenges (exhaust heat melting wires, etc.) as your 7age? Did you add some sheilds? Or route differently? Keep up the great work.

The first gens radiators are a lot thicker than the 2nd gen radiators. When i had it in my 7age tercel, the engine struggled to get past 170*F. Wasnt a thermostat issue...all i could chalk it up to was the hood scoop was helping cool the motor while I was driving. If the stock radiator (which is a NOS one I picked up about 2 years ago) cant handle the extra heat, Ill look into the civic radiator.

Heat challenges, the only one I can think of is the clutch cable since it will be routed right next to all the exhaust.
