GDII's 1990 G-Limited

[GDII]

So 4 months have been and gone. I have still been focusing on moving this project forward. It's just been a bit slower than before.

Gathering parts slowly to make this thing a reality.

I have a 3" intake from GlanzaAtHeart. Thank you! It's a TCS Motorsport assembled kit.
It's essentially a 3" 45º stainless steel pipe with 3 hose fittings welded onto it. 1 for idle valve, 1 for the PCV off the back of the valve cover and one for the BOV recirculation. It comes with a 45º reducer from 3" to 2.75" for the CT series turbos. It also comes with a generic Pod filter with fake carbon print on the top. You only find this out after you buy it. It's funny what you get in kits from aftermarket places, no better than buying a generic mass produced filter that many brands or no name brands sell. This is no reflection on the previous owner of the parts. Here is this particular one. A WS002CF. Even Simota sell it as their own.

Future plans are to create an airbox with bell mouth and using a TRD panel filter from a JZA80 Supra. It's actually a part that will fit in the Caldina OEM airbox so using this part is sort of a hark back to the OG car. The filter is luckily still available at this point in time.

And yes, I tried it on the Corolla with an adapter ring as the throttle on the 4AFE is tiny. Was expecting a better sound from the intake but no, barely changed it so took it off.

Have you ever seen such a clean throttle body? This has NEVER been cleaned since 1997. I know this because I know the original owners, they would never do that. You can see speckles of dirt on the bottom of the plate. This is an NZ new car so has no emissions on it so both the PCV hoses go into the intake manifold after the throttle plate. This also means the idle valve will be very clean.

My oil pump is a little worn so a new one has been obtained from pbaron. Massive thank you Pierre!

Part number 15100-88561.
This comes with pre-installed shaft seal and o ring. Part numbers are 15165-88382 for the shaft seal and 15188-74050 if you buy these individually. They don't come in the main gasket set for the rebuild kit as mentioned a few posts back.

Toyota Genuine parts!

You can see just below the hole for the crankshaft there is a cut out for the crank angle sensor. The GEN3 3SGTE pump does not have this.

This means I will have to remove a few more parts off the engine than I was planning but it gives me a good chance to check things out and clean stuff up a bit more. The lower sump, upper sump and windage tray plus oil pickup have to come off to replace this. The sealing face to the block has a paper gasket from the factory but new one in the seal kit is steel. Getting the paper gasket off is going to be difficult.

The engine is looking very clean mate. Good luck in getting the paper gasket off to install the new timing gear cover. Sparkly clean engine

Lots of sharp edges on that oil pump
best you "port" them out I have a die grinder you can borrow

Haha what's you and porting oil pumps? These are completely different to the 4AGE pumps and flow perfectly fine for 7000rpm.

Sharp edges can cause cavitation. If you've got the opportunity to clean the sharp edges off, then it should be done.

Well yes, I get that. There doesn't seem to be anything online saying that I should or even how to do it to these pumps. Happy to be shown what is important on the 3S pump to make it better than it already is.

The benefits of smoothing out entry and exist of the oil pump are there. They will only help the pump slightly in the delivery of the oil " less cavitation" and possibly less heat input due to the lower cavitation , you will get more flow (volume ) of oil for the same amount of work done buy the pump ( fuel economy ) but if you are staying stock all in all not worth doing as Stock engines last in to the 300 000Km range if looked after.

Yeah, I see the benefits but around the pump itself it's pretty good.
Stock engine, not planning mods, if I do then I'll see what needs doing and the whole engine will get stripped down for new internals.
This engine already has 307,000km on it and is extremely quiet so no issues there.

Birthday time!!

When your wife orders you engine parts for your birthday that you had no idea about and it's a part you actually need. It's a good day!
Massive thanks to Richard and Mark at Manawatu Toyota for helping her sort it out for me.

Water Pump Set Part Number 16100-79226. It comes with the pump face and the pump housing joint together over a steel gasket instead of a paper gasket. It also has the O ring from the the pump to block, water bypass from coolant tree to back of pump housing and gasket from the heater return hose to back of pump.

My eyes hurt so many sharp edges........

The water pump does have quite a few sharp edges. Again, probably not going to do anything as it's not a performance build.

Nice one. Can’t remember if the WP is any different than the gen3. I bought an OEM like yours which came with all gaskets. Oil pump looks the same as gen3 although there may be different internal parts such as relief valve. Never knew anyone who replaced whole pump as apart from a couple of seals, they are bullet proof.

The water pump is the same as the GEN3 3SGTE and GEN3-5 3SGE. However the oil pump is not. It has the area for the crank position sensor. It's the same for the GEN4 3SGE ie BEAMS redtop and greytop and for the GEN5 3SGTE.
The relief valve isn't part of the pump assembly, it's in the upper sump. The pump setup is probably the same but due to the crank position sensor it's a different part number.

Mine is a little worn out after a long service life and this one was available for a great deal so I decided to take it.

It's true, generic Chinese made pod filters aren't as great as the name brand ones. Im surprised it didn't make any audible difference in sound on your 4AFE, maybe with a steel or alloy pipe added in there it might resonate a bit louder?
