Tech:Engine/T Series/Blocks

2008-06-15T11:21:53Z

Too quick:

The Toyota T series engines.

2T, 2TC, 2TB, 2TU, 2TG, 2TGR, 2TGEU, 2TGU

1588cc

Bore = 85mm and Stoke = 70mm.

The 2TG head is a twincam 8 valve varient cast by Yamaha for Toyota, All others are pushrod HEMI style 8 valve heads.

There is a difference between early and late 2T blocks, so the starter motor won't bolt on if you got the wrong one. let's say you want to use a late model starter motor on an old block, you have to change the plate between the block and flywheel to the newer type.

Then you can grind off the little tap on the starter and mount it upside down, that worked for me :)

late model flywheels is the lighest, but still way too heavy.

3T, 3TC, 3TU, 3TEU.

1770cc

Bore = 85mm and Stroke = 78mm.

Tech:Engine/A Series/Installing EFI Lifter Pump into AE86 Fuel Tank

2007-06-28T10:09:55Z

Too quick:

During my 4A-C to 4AGE engine conversion in my Australian AE86 sprinter it came time to upgrade the fuel system to be able to meet the new demand for fuel. Being a naturally aspirated engine beforehand there is no in-tank fuel pump, only a mechanical fuel pump on the engine (driven by the camshaft). Japanese AE86 Sprinters on the other hand came from factory with a 4AGE engine and the EFI tank to suit. I had 2 options, find a tank from a Japanese AE86 (Can be expensive) or install my own generic lifter pump setup inside the tank. I opted to use a VK/VL Commodore lifter pump inside the tank. (This setup could also be adapted to other non efi tanks (KE70/AE71 etc).

(Lifter pumps are designed to suck the fuel, not pump it at a high pressure so you will also need to use a Hig pressure external pump with this setup).

----

To start with I removed the fuel line setup from the top of the fuel tank.

----

The Lifter Pump will be fitted where the old in-tank fuel filter is, it can be removed easily.

The Lifter Pump I'm using is from a VK/VL commodore

----

Here is what the Lifter Pump looks like with the fuel filter on.

[[Image:Post-6-1128150575.jpg]]

----

I had to hacksaw a fair bit off the end of the fuel pickup line to get the lifter pump to sit where it needed to in the bottom of the tank. A few test fits and I clamped the lifter pump to the fuel pickup line.

[[Image:Post-6-1128150788.jpg]]

----

Here is a shot of the Lifter pump mounted to the fuel pickup line.

[[Image:Post-6-1128150962.jpg]]

----

This is the VL Commodore In-Tank Lifter Pump assembly I bought from the wreckers for $55.00, I bought this for the wiring connector and the wires. I Decided against running normal wire inside as I don't know how long it would last before the petrol chewed it away. An auto sparky I taked to said the same thing I was thinking, use the wiring out of another in-tank setup.

[[Image:VL Lifter Assembly.jpg]]

----

Here is a closeup of the wiring connector that I removed to install into my setup.

[[Image:Post-6-1128748835.jpg]]

----

Another advantage of using the wires from the VL lifter pump setup is that the connectors for the lifter pump wiring are already crimped and properly insulated.

----

Here is a photo of where I drilled a hole in the AE86 fuel line setup for the VL wiring connector to go.

VN Commodore's use the same wiring and a very similar fuel pump as VL commodore's, The VN pump is longer so more of the ke70 in tank piping would need to be cut off. All the instructions above are the same for Ke70/Ae71.

It is best to to use wiring from another fuel tank as normal wire insulation might get eaten away from the petrol.

Make sure you get a VN in tank pump for a lift pump as the VP in tank pump is a pressure pump. You can use just one pressure pump in the tank but it WILL surge on hard cornering with 1/4 tank or so and that can lead to your pump seizing and failing.

The Ke70/Ae71 fuel tanks are not baffled nor have an internal swirl pot.

Tech:Engine/A Series/Converting to RWD

2006-12-29T12:57:56Z

Too quick:

Converting A-Series engines to RWD can be done.

List of things that you might want to consider when installing a 4AGE based engine into an KE70/AE71/AE86.

[[Crossmembers]]

''Engine Crossmember'' - You can use the engine crossmember from an AE71/AE86 as the engine mounts will bolt straight up. If you have a KE70 crossmember, you will have to get custom engine mounts made.

''Gearbox Crossmember'' - You can use the gearbox crossmember from an AE71/AE86 as the gearbox mount will bolt straight up. If you have a KE70 crossmember you will have to re-drill some holes to mount the gearbox.

[[Engine Mounts]]

You can use the engine mounts from an AE71/AE86 4A-C engine or have some custom made. Realise that custom made engine mounts require engineering.

[[Flywheel / Clutch / Pressure Plate / Throwout Bearing]]

There are 2 different size 4AGE flywheels, for 200mm and 212mm clutches. If yours is the 200mm clutch, just buy an AE71/AE86 200mm clutch kit. If yours is the 212mm Clutch, you will have to buy an AE92 100KW 4AGE 212mm clutch kit (also you will have to buy a throwout bearing from an AE86, as the AE92 clutch kit throwout bearing is completely different). Apparently the 212mm clutch will get better grip as it has more surface area.

[[Spigot Bearing]]

FF / MR mount 4AGE engines do not have a spigot bearing in the crankshaft. You can press a spigot bearing from an AE71/AE86 4A-C into the crankshaft. Part number for the Spigot/Pilot bearing is 6001 from most bearing shops.

[[Gearbox]]

There are 2 main options for a gearbox

''T50 Gearbox'' - You can source a T50 gearbox from an australian AE71/AE86 or get one from an imported AE86. There is 1 main difference between the australian and japanese T50 gearboxes. Both of these should handle stock power without a problem.

ADM T50 (Australian Domestic Market) - Clutch fork on passenger side of car.

JDM T50 (Japanese Domestic Market) - Clutch fork on drivers side of car.

''W5x Gearbox'' - You can use a W55 gearbox with a bellhousing adapter, people usually swap to these when their engines are putting out high power figures as T50 gearboxes are a lot weaker. Note that you will have to modify your tailshaft to suit the different gearbox output shaft.

[[Clutch Master / Slave Cylinders]]

If you install a 4AGE into a KE70, it is easiest to put the pedal box and clutch master cylinder in from an AE71 (as the KE70 came with a cable clutch). With an AE71/AE86 you should already have a clutch pedal and clutch master cylinder (provided its not an automatic gearbox). You can use whatever slave cylinder came with your gearbox, though you may need to get the metal clutch lines made up.

[[Tailshaft]]

What tailshaft option you take depends on what gearbox you have and what diff you're adapting it to. Some people decide to have a custom 1 piece talshaft made out of their existing tailshaft. Also you may chose to install a tailshaft loop in case the tailshaft decides to let go.

[[Intake Manifolds]]

There are 3 options for your intake, these are also dependant on if your 4AGE is smallport or largeport.

''JDM AE86 Intake Manifold'' - The stock intake manifold that came on the large port blue top 4AGEs can be used if you already have one or are able to source one cheaply. You can use these on a smallport motor but you will need an adapter to go inbetween the manifold and the head.

''Cut n Shut Intake Manifold'' - This is a popular option for converting the FF / MR intake manifolds to a RWD layout. This is probably a better option as they are more common and cheaper to buy. You will have to find someone that can cut the throttle body mount off and swap it onto the opposite side of the intake manifold.

''Quad Throttle Bodies'' - Nothing beats the sounds of quad throttle bodies, its a good way to go if you want a tough N/A engine.

[[Cooling System]]

''Radiator'' - A standard AE86 radiator will have no problems keeping a 4AGE cool.

''Rear Water Outlet'' - Some rear water outlets will want to brush up against the firewall, an AE82 4AGE rear water outlet is very similar to the JDM AE86 4AGE rear water outlet and should clear any firewall. A 4AGZE rear water outlet will clear the firewall no problems on an AE86.

''External Thermostat'' - If your 4AGE came in a FF or MR layout, you will want to run an external thermostat. This means you will have to cut some of the origional piping, be sure you mount it low so it doesn't get any air locks inside.

''Thermo Fan'' - To keep the radiator cool, install an aftermarket thermo fan, you will also want to fabricate a shroud to direct the air flow across the radiator.

Too quick:

If you are wanting to put an a series engine into a ke70 you can use the ae71 cross member. The picture below shows the difference in the mounting positions. The black greasy one is a ke70 crossmember.
