Unless it is particularily laggy, you might be fine with the preload. Usually half a hole of preload is about right. Exhaust backpressure can cause a lower boost pressure, as actuators rarley make their rated boost.

The newest addition to the collection. A 92 G-limited that has been converted to a Gen 3 3SGE. 
More pictures to follow as we give it a new lease on life. 




 

I have been a bit lazy in updating where Im at with the G-Limited. But it has certainly been interesting finding the good points of the car and the bad/unusual points as well. 

The good points:
- Majority of the paint seems as if it will come out quite nicely after a cut and polish.
- Mint interior. No rips, no tears (except the steering wheel) and looks better than my 94.
- Suspension is sorted. Old school Apexi strut and spring setup in the front and stock struts with King springs in the rear.
- Minimal body rust (only one small spot where the T-bar meets the roof again).
- Free new pod filter on the engine
- Free new Eagle ignition leads.
- New distributer cap

The bad/unusual points:
- Unsure of the actual year of the car. Its either a 1990 or 1992. Dont really want to pay for a Revs check and Toyodiy doesnt return any results as it doesnt have the original VIN due to it being an import. 
- Lots of little dents on the drivers side. 
- One severely gutter rashed wheel.
- Gouges on the rear bar.
- Broken front bar.
- Blown Gen 3 NA engine wired up and running a Gen 2 ECU  (The loom is a terrible hack job).
- Even though it is a Gen 3 it has a Gen 2 gearbox meshed to it and is still running a mechanical speedo (bugger). So it seems like I will be meshing this gearbox up to my rebuilt Gen 3 as converting to electrical is a PITA.
- Heat damage in engine bay from the engine. The underside of the engine lid is black with soot or something. 
- Very poor cooling system. Seems it has been running only water for many years.
- Very poor condition fuel tank. 

Here a few pictures for those who don't like reading 




Absolutely rooted. Also note it has from what it seems is EGR components hanging off the intake manifold above the Exhaust manifold. My other Gen 3 doesnt have any of that....Im guess they only had that in J-land. 

 
Out with the old!

 
Taking the dreadful fuel tank out. Also note if you look closely it has a drain plug in the center of the tank. Im guessing this isnt stock as my 94 didnt have one. But this seriously is a good idea...made life a lot easier!

 
You should see the inside of the tank! 

 
So whats next?
 
Well currently the radiator and the fuel tank are off to be striped down and reconditioned. A new fuel pump will be ordered soon enough and I have just received brand new silicone radiator hoses.
So with any luck in the next few weeks the new engine will be in and then the wiring begins.....

The yellow car is going good. I believe it has, though I havent taken off the intake pipe to see if there is any oil present. But the last time I had the intercooler piping off I gave them a really good clean getting rid of a lot of caked on oil inside them. Since then, in the midst of trying to figure out the boost issues Im having and replacing all the intercooler couplers with new ones. I checked the top of the turbo (outlet heading towards the intercooler) and it is still squeaky clean. So Im thinking it might of had a bit to do with the PCV and old caked on oil heating up and running backwards. 

As I mentioned, I am still having boost issues. But once the red one is off the hoist I plan to get the yellow one up on it and re-adjust the wastegate preload. If that isnt the issue; Im wondering whether I might have a vacuum leak. The car idles (when warm) on -16/-17. I havent found anything in the BGB to whether that is normal or not. 

Hmm I have had a look there and didnt find any other numbers, other than the one riveted to the wall. Would it be anywhere else?

That plate is likely over the top of the original one. But id say your jdm vin is SW20-0005629 as that is the correct format from memory.

Okay awesome. I just ran those numbers and it returned saying its a 1990 model. Cheers Nick!

Don't know exactely which models do or don't, but some have drain plugs for the fuel tank.

That's certainly interesting, I wonder why only some and not all.

Very small update:
I went back to have look at both the mechanical and electrical speed senders today. As I wanted to see if it was possible for the mechanical sender to be swapped over into the Gen 3 S54. As it turns out it can and meshes nicely. I wont know for sure if this will work until I have it back in the car, hooked up and driving but it seems at this point in time I may not need to mesh up the Gen 2 S54 to the Gen 3 to retain the mechanical speedo.  

Hey Declan, what are you doing with the old gen3 na motor? Want to sell me the throttle body tps sensor cheap so I can see if mine is stuffed? :)
