One word: Awesome!

Fuel Consumption #3

2008-10-10T00:59:00.002+08:00

Verdict: Improving! Which is good. Let's hope it keeps on improving.

The car's been getting between 11.2 to 11.8 km/litre.

I suppose I should be happy that the 11.8km/litre run was done mostly on the way up to Penang between speeds of 110 to 140km/h. =)

Before and After

2008-10-10T00:14:00.009+08:00

This post is way overdue. Here goes.

Before:

The 4G93p before rebuild.

Dirty cylinder head.

Dirty old piston.

The crankshaft, before cleaning and balancing.

After:

Engine block after rebore.

Cylinder head after cleaning.

Cylinder head after 3-angle valve cut.

New pistons! With the conrods, after balancing.

The entire bottom end after balancing.

The clutch after balancing.

Balancing marks on the crankshaft.

The flywheel after balancing.

The 3-angle valve cut job. Up close.

New ACL bearings..

Exhaust ports before porting.

Exhaust ports after porting.

Intake port before porting.

Intake port after porting.

Fuel Consumption #2

2008-09-02T16:13:00.002+08:00

Petrol: Shell Super

38.81 litres to 420.8kms
10.84 km/litre
9.22 litre/100km
RM0.24/km

I suppose its pretty ok for a 1.8 in mixed city/highway conditions.

note: previous petrol was Mobil

Fuel Consumption #1

2008-08-17T23:50:00.002+08:00

First fuel consumption is in:

40.58 litres to 438.4 km
10.8 km/litre
9.26 litres/100km
RM0.25/km

Thats slightly below expectations =\ I was hoping to get around 12km/l.
Hoping that its partly due to the ecu still finding the optimum settings.

Finally!

2008-08-15T00:47:00.002+08:00

The car's finally back from the rebuild. 35 days without a car. Not easy.

First impressions:
Throttle response improved quite a bit. The car feels more eager and changes speed to the slightest touch of the pedal. Engine feels smooth. Can't really tell for sure now since I'm limiting it to 3000 rpm for the first 1000km. Gearshifts are also very smooth now - a bit too smooth for my liking though. A short-shifter could rectify this, perhaps? Hmm.

Waiting (im)patiently for the break-in period to be over.

Engine Rebuild

2008-07-29T18:06:00.001+08:00

What is an engine rebuild job?
Its like a full overhaul, and some more.

This is a summary of what will be done to my engine:
- Engine is stripped down completely and cleaned.
- New Parts: Pistons, Piston Rings, Gaskets, Con Rod Bearings, Main Bearing, Timing Belt, Water Pump, Clutch, some Valve Lifters
- Services: Block Re-Bore, Valve Cut, Bottom End Balancing, Port & Polish

To Make God Laugh, Tell Him Your Plans

The Original Car
1994 Wira Sedan 1.5GL
4G15P SOHC (carburetor)
64 kW/87 HP @ 6000 RPM
118 Nm/87.4 lb-ft @ 4000 RPM

The Great Plan
(i) sticking with the original engine and getting more out of it
(ii) engine transplant

I didn't see much point in modifying a 14 year old 1468cc carburetted engine. (Weber carburetors or BOT kits etc)

So, engine transplant it is.
(i) 4G92-MIVEC
(ii) 4G93P-DOHC
(iii) 4G93T

I'm an NA fan, so the 4G93T was out. After testing a MIVEC satria, I realised that I prefered more torque on the lower end for daily driving. Unfortunately, JPJ had to go outlaw 2000cc conversions. That made the 93P prices shoot up like crazy. Bah.

God: Haha.

----
The Other Great Plan
Engine conversion plans were put aside since I had no cash to do it. So I thought, ok, lets stick with this car for another 2-3 years, then I'll sell it off and get one of my dream cars.

Like this one.

Then one fine day, the 4G15 started sputtering and choking. Replacing the spark plugs solved the problem temporarily. It was a matter of time. My driveshaft and bottom end were starting to go. Engine was leaking oil as well. Bah #2.

God: LOL.

----
The Other other Great Plan
(i) Transplant a 4G93P-DOHC from a Satria GTi or a Putra to give the car new life
(ii) Overhaul 4G15 and use it a few more years

~~A thinner~~ An empty wallet and 2 months later, the new engine was in my car and I was grinning face to face.

Me: =D

3 months later, I had a faulty fuel pump, and damaged conrod bearings. Bah #3.

Me: =(
God: ROFL.

----
~~The Another Other other Great Plan~~ Plan #463
(i) Rebuild my engine
(ii) Sell car

I'm going with (i). Car being fully paid for and all. Didn't want to get into a 5/7 year loan.

God must have been laughing.

This is not a blog

Lately, I've been thinking.

...

Thats still coming along, somewhat.

They say that you function better when you take notes, write a journal, etc. Things I defenestrated all this while. Funny, what finally got me thinking about giving this a try wasn't any of those reasons. A box with four wheels. That's what got me started. This same box will in all probability get me broke or killed as well.

This is a documentation of sorts. It's NOT a blog.
