Re: From Michigan with Love
Welcome on board
You look to be doing an excellent job on the refresh. I rarely see an AE86 in Michigan, let alone three at a time. Good luck on the build.

Re: AE86/AW11 4A-GE Oil Pan
I did a big port FWD into a RWD. No problem with the oil pan. You will have to change the oil cooler hard line going into the oil pan. Also the cooling fittings. Depending on what accessories used you may have to swap water pumps and pulleys etc. Before dropping in the FWD motor, verify that the mot...

Re: My red hatch (fix-up and restoration)
Sorry for the late reply. I fitted the 2nd breather to the rear of the intake cam cover. I drilled and taped the cam cover for 3/8 NPT. The cam cover is not that thick of material. I shorten the right angle fitting and put epoxy around the inside surface to get better thread contact. The cam cover h...

Re: AE86 T50 JDM/USDM Transmission Question
All T50 gear ratios are the same. The speedo drive and bell housing could be different. [Several different models used the T50 trans} If the trans is known to be from an AE86, then you are golden.

You can apply at the state level, for a new VIN. You are registered as an assembled vehicle. Each state will have an inspection check list, which is needed to be able to verified, before they issue a new title.

Re: 4AGE BT: To Keep or Not to Keep
If the engine is really reading that high in compression, then it is probably in very good shape. I would just make sure to use a good oil and filter and change it several times after installation.

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.

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...

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 ...
