More done today...
Stripped down the CT20b to the CHRA.
Discovered it has a ceramic turbine wheel unfortunately
Comp and turbine wheels look in good condition though.
Also did some more test fitting various parts of the engine.
All good so far, cant see any problems besides the plastic cam covers not fitting up (was expected).
Need more room in the shed, there is half a RA28 (RA29 '77 Celica for you Americans) 1UZ-FE project in there too

looking good man!
couple of questions...
- what oiling system are you going with? gen 4? Just so u know ATS racing and an automotive engineer both have determined that based on impeller size and design the gen 4 pump flows more oil than any other compatible 3s/5s pump design.
- do you plan on upgrading your cams? and if so how do you plan on overcoming the hall sensor dilemma on the head?
- What EMS are you running?

I only heard that info about the Caldina pump being better after i sold my gen3 sump
So ill be running the +98 5S pump with a modified gen2 sump or Moroso sump.
Staying with the factory Caldina cams for the moment.
If i wasnt, fitting the sensor tooth to the end of the cam wouldnt be much of a problem.
ECU will be a Megasquirt3 + MS3X.

Very pretty!! Keep that shit going
Progress has slowed a bit recently due to having to move house.
I need to solve this, will have the down pipe from the bypass lines cut off and a appropriately sized barbed pipe welded on:
A Moroso sump is a no-go for me at the moment, mainly because im concerned with its durability.
This car will go off-road fairly often, and i dont want to end up with a small sump hit cracking the alloy.
So, ive started modifying my gen2 sump using sections from a 5S sump.
The increased size:
Making up the pieces from sheet steel to fill the gaps:
#4
Pickup location... ill build a hinged baffle system around it.

Nice build thread. Enjoyed going over it all. I do have oneeeeee question though... May I borrow that engine for a few years... Just a few.

A few reasons:
- Wanted a factory crank sensor, so limited to gen4 or +98 5S.
- I wasnt aware at the time that the gen4 pump was the most capable (thought the +98 5S was).
- Finding a gen4 sump would have been very difficult.
- Had bought a new +98 5S pump for 99c on eBay
