Well I've decided to forget my ideas of car audio and go for a bit of performance. I've looking at getting what Starlet GT parts I can for my Sera and to try to do a cheap turbo conversion (cheap because I'll be using all used items for the most part). I'm going to start with the CT9 turbo, and once I have that running reliably start swapping parts over for better items (eg the exhaust manifold will probably be first thing to get replaced).

I'll be leavening the 5E-FHE stock to start off with and run low boost (6-7 PSI), eventually getting my spare engine worked on and the compression ratio dropped.

Current list of lined up parts
- CT9 Turbo
- 4E-FTE Exhaust manifold
- 4E-FTE Injectors
- 4E-FTE ECU
- Oil and Water Lines
- Oil Filter Relocator
- 4E-FTE Sump w/Pickup
- 4E-FTE Wiring Loom
- 4E-FTE Map Sensor
- Random Gauge
- Random Blowoff Valve

Bits I still need
- Intercooler
- Intake Piping
- Exhaust
- Fuel Cut Defender / Some kind of fuel controller?
- Thermostat Housing

My first point of the unknown is the ECU, I think its manual (and I have an auto Sera), should I just keep the stock 5E-FHE Auto ECU and run something like a fuel cut defender or fuel controller piggyback style, or try to source an Auto 4E-FTE ECU?

well done scuzzy lad, i am definatly waiting in anticipation for this one :D

definatly run low boost on a 5e at first, I dont think anyone has properly proven that the 5e pistons cant handle the conversion but the fte pistons or custom ones would be the ones to go with.

Yeah, lookin forward to this one dude...... :P

My take is:

5E-FHE ECUs are the same, year for year, between auto and manual.

4E-FTE ECUs differ. The difference is that the 4E-FTE auto box has two electronic modes, a power mode where the gearbox hangs onto the lower ratio for longer and, I think, a 2nd gear start mode for poor grip conditions.

I think you could run an auto Sera on a manual 4E-FTE ECU - just needs someone brave to try out my theory.

That powermode sounds interesting, I wonder if its linked to the High/Low boost dash button of a Starlet. Might be worthwhile trying to track down then.

The hi/lo boost function is just that

The auto box buttons involve a lot of extra re-wiring as a Auto ECU has 3 plug ECU - 26 pin + 16 pin + 12 pin, whereas the manual ECU has 2 plugs like the Sera - 26 pin + 16 pin.

I run a MicroTech LT8s custom ECU - a great item even though it pushes over $1000AUD with the controller module.

throttle bodies - at least two different types of plugs - select one which has the same connection as per your car. I think its pretty similar to the standard 5E-FHE one

Inlet manifold - should be same as existing one.
Fuel injector rail - should be the same.

the distributor is identical to a Sera one as well.

Correction - inlet manifold is 99% the same, but has the air temp sensor in the front - silly me - you'll need this, but match it up to a throttle body that fits your wiring
