nzae86's TRD ae86 N2 Race Car Project 2,

Hiya, amazing build
Have you ever taken a look at the articles over at autospeed.com? They have done a lot of interesting experimentation on air filters, cold air intakes, ram air etc. Might provide some inspiration?

Hi, very nice build (not read the entire topic).

Regarding the fluid reservoirs for the pedal box. Aren't you afraid when you build up lateral G in a right corner that fluid will be pulled away from the cylinders?

With remote reservoir it's probably a better idea to keep the reservoirs exactly above the cylinders to avoid problems with fluid shifting due to cornering force.

Just my 2 cents.

Thanks for your comments ,
I think that the remote reservoirs will hold enough head of pressure in them that the only time that there will be a lack of fluid at the master cylinder is when the car is upside down . It makes no difference whether the reservoirs are directly above or to one side of the master cylinder as the forces on it are the same .
cheers

Just read the entire thread, fantastic build.

I aspire to be able to build a car to a similar quality one day.

It's also great to see your patience and persistence in answering questions about the build.

One question about your TRD injection manifold...

Almost everyone who I've talked to has insisted that the best way for trumpets is to have a large radius/lip, and the trumpets projecting into an open space, rather than flush mounted against a plate. As apparently a lot of the air flow comes from up around the sides.

How did the original TRD setup operate, were they enclosed in a box?

I have seen another picture that had a carbon fibre box on the end of what appears to be the TRD injection manifold, but with bellmouth extensions on it.

nzae86, why not make an air box in front of the wheel then make a hole up in the front wheel arch so that you can make a top enclosure for it. Then make a big air sucking piece in the front bumper to connect it to.

Then it would get driving wind pushed into the airbox which can be suckted up by the air filter.

This engine is not quite as radical as my track car so its air supply is not so critical.

Is that a AE101 airbox turned around? looks neat! I recall the T3 ITB manifold mounts the throttles upside down.

Hi thanks for the link , I have had a read through their articles and I think I'm heading in the right direction.

These throttle bodies where used on the cars with an air box to suit the swift and ralt chassis , they did run a very small trumpet on the end , but the throttle body has a machined bell mouth in it as part of it's manufacture. I suppose TRD would have done a huge amount of testing on their setup , as you can see that this is the later setup where they ran the injectors from underneath the body , firing the fuel to the top of the inlet port giving it better atomization and swirl.

Good idea , but not wanting to cut any holes is an issue , the other simple option is what the Toyota factory teams did back in the days when they ran these cars as group N , as the rules on radiator size was free , they made a radiator about 6'' narrower than standard , then built a vertical intake beside the radiator and ducted the air towards the throttle body intake .
I know that a cold air supply is important but in a 4age rwd car the exhaust is on the other side of the engine bay and when I have the headers coated the heat output is a lot lower and there is no turbo generating large amounts of heat .In all my time of racing and rallying these cars we have never had an issue. I like the theory of" Keep It Simple"

Good spotting , yes it is from a ae101 but I reshaped it alot to give the box more volume by cutting and welding a complete new shape to the part that bolts to the intake , as you can see the sides of the air box are now vertical, then a made a mold from my new shape then made my air box from fiber glass.

The T3 adapter does mount the bodies up the other way however I built my own and mounted the bodies up the normal way.
