Re: Return #5: Spare engine boogaloo
The collector design is your typical straight wall tube. To develop a reflective wave the at the end of the collector it must open into the atmosphere, and NOT into your typical tail pipe. The other option is to dump the exhaust into a large canister. Which is next to impossible to package! The idea...

Re: Return #5: Spare engine boogaloo
You are correct on the assumptions. Realize that the collector must be [[ open at the end,]] for the correct wave to return back to the head. If dumped into a typical exhaust system you need an expanding area at the end of the collector that is 4 times the volume of a single cylinder and is beat sha...

Re: Saving a crusty 16v 4age
Killer job on the engine and it looks great! Depending on how long the engine will be setting [YEARS?] You are probably better off letting it set with the assemble lube Vs running the engine and then setting. Look at high zinc or break in oil for the first start.

Re: Injector firing
The big port injection system is very primitive, when compared to current systems. The injectors are fired in pairs for two cylinders at a time! I do not believe there is any way to alter the injection timing with a stock ECU. One cylinder is always going to be to early, or to late relative to valve...

Re: What gear oil to use in T50 and Diff?
I have had very good results with Red Line MT 85 in the trans, do not use any GL-5 rated oil in the trans, because of the syncho's made from a brass alloy. For the diff, I use Valvoline 75W-140 with 4oz of Ludrilon gear treatment. I would not use any type of additive in the trans, only GL-4.

Re: Steering Rack U-joints AW11 vs AE86
I'm using a U-joint from a 1991 Camry, which is slightly longer than the stock AE86 joint, but there is enough spline on the steering column to fit it . I'm also using a stainless steel U-joint from Flaming River, that is about a 1/3 of the cost of a Toyota joint.

Re: Head cc volume on 3 rib bluetop MAP setup
A standard big port 4AGE head will have a typical volume around 36 to 36.3cc’s and a chamber volume with a standard head gasket of 39cc. Note an un-cut head is 116mm (4.566”) thick. Taking a .004” thick cut on the 4AGE head will reduce the volume by about .5cc’s. If you use a thinner then stock head...

Re: Anyone knows the name of this hose and the part #?
Yes, the air from the engine cam cover enters the intake throught the hose. The 4AGE only has baffles in the cam cover and no PVC. That is why you see some cars that auto-cross during hard cornering have a puff of smoke from the exhaust, because the intake just got some oil sucked in from cam cover ...

Re: Anyone knows the name of this hose and the part #?
That hose is for venting the crankcase gases. The 4AGE hose dose not have a PVC valve in it. [Positive Ventated Crankcase.]
It is not a special hose! Any hose with a tight fitting ID can be used as a replacement.

Re: Overheat problem on small port 4AGE
Sounds like a head gasket. Do a compression test or leak down test. Typically cylinders number 3 or 4 are the ones that fail.
Do not use a cheap replacement head gasket. Use Toyota or band name like Fel-Pro headgasket.

Re: Headache and a Half -starting/rev cut
I think you are on the right path with the fuel pump. Let the car set over nite and than crack the fuel rail banjo fitting and see if you still have high pressure in the system. Sounds like the pump check valve is leaking down and the pump can not keep up with pressure and volume at higher RPM. Davew7
