  1. They differ in design and the material content which can effect weight, expansion and strength.

    However for most application the capabilities of any will be fine, it's only when really pushing the envelope careful consideration needs to be given.

  2. I don't see an issue with running them daily and I always have, it's what they were designed for and as long as you keep on top of maintenance they should be fine. I do see people's point though when there modded to be so highly strung, Paddle clutchs and stripped interior can make the commute a bit wearing😬

  3. Well after having an enjoyable summer with the car, the nagging feeling that I would have to come to a decision whether to spend more or find a replacement, was playing on my mind.

    Obviously not being able to think of a worthwhile replacement new or old that would offer the uniqueness and enjoyment without considerable more financial outlay the decision was made to rebuild/refresh the engine.

    In order to do this I needed somewhere to carry out the work and after looking at the options and hassling friends and family, I was able to get the use of my Dads Garage but it was two hours away. So I planned the time I had and once again I used my annual two weeks holiday in August to work on the car.

    I booked off a long weekend a month before my holiday so I was able to spend three days removing the engine cleaning and bagging components ready for the machinist and reassembly. As I did have a engine crane at this time I broke the engine down in order to remove it.

    Auxiliaries removed

    Head off

    Pistons out- Things dont look to bad on the crowns but there is a lot of carbon build up behind the rings.

    Main bearings- Some scoring

    Big end bearing- worn through to the copper maybe I pulled it apart just in time.

    Valves out

    Head gasket- Blown between 2 and 3 which might explain the poor running

    The Jam Manifold is showing its age with a number of cracks and I dont know how much my proting ten years ago helped but its got more life in it and its going back on.

    For reference the engine had completed 212721km upon removal with more than half of that at 1bar on fpr a testament to the quality of engineering I would say well done mr Toyota.

    With the weekend over I wrapped up my head, crank, block, pistons and valves to take home so that I could deliver them to my chosen machinist as well as spending my free time to get everything cleaned up.

    The Machinist was to deglaze the bores and deck the block, they identified that the exhaust guides were worn beyond tolerance which would explain the smoking so they were to be replaced and the valve seats recut and valves refaced, as well as skimming the head. The crank was then to be checked and polished.

    I was able to collect the engine two weeks after dropping it of allowing me time to give them another clean and deburr.

    All the replacement parts were then to be ordered so I made many a list to work out what I was able to afford within budget.

    The list comprised of:-

    Engine Machining, Gasket Set, Oil Pump, Piston rings, Cambelt kit, Tensioner spring, Head bolts, Ignition leads, Oil filters, Coolant, Paint, Sump sealant, Loctite, Torque wrench, Engine Crane, Engine stand, Cylinder head stand, Plastigauge, Manifold nuts, Fuel hose, P Clips, Piston ring compressor, manifold studs, AC Grommet, Oil, Transmission fluid, PCV Grommet, Valve lapping kit, Decat fixings, Bearing set, breather filter.

    Then the enjoyable part of receiving all the parcels started and once I was off work I was able to get started on the build.

    The pile of parts

    I got the engine on the stand and gave it, its first coat of paint

    I then placed the crank in and took some measurements to ensure everything is within tolerance.

    Everything was then cleaned for the umpteenth time and I assembled the bottom end.

    I was then able to start work on the head and I planned to mildly port the head before assembly matching to the gaskets and removing the step where the ports meet the valve seat as well as shaping the combustion chamber slightly.

    With this complete more cleaning took place and reassembly was able to occur.

    I then spent hours trying to achieve the valve clearances so they were as close to perfect as I could manage.

    The head and block were then complete so it was time to put them together, as with the mains I wound the bolts in and out a number of times to ensure the threads were clean and they would be torqued correctly.

    With that achieved I then cleaned and painted all the auxiliaries, and start building the engine up further. This being one of the more rewarding parts of the build.

    As the engine was almost complete it was time to prepare the engine bay so I gave it a good clean and stripped the headlights of to treat and paint any tired areas. I need a new crash bar.

    It was then time to bite the bullet and get the engine back in the car, so with my Dad taking control of manoeuvring the crane it was soon in and bolted to its mounts.

    The following day was then spent plumbing everything in and ensuring nothing had been missed.

    image_zps0xdujfbm.jpeg

    I then just had to turn the key, with the plugs out and efi relay removed it took a considerable amount of time to build oil pressure, all the while my mind was filling with doubt. After removing the filter and using the funnel and pipe method to prime everything the light went out and it was the moment of truth.

    It started! but whats that noise? I was searching all around and it would disappear when the throttle was blipped, then when checking underneath I felt a blow from the exhaust. I only forgot to plug the hole in the decat for the stock heat sensor Doh! Lol.

    With that sorted, all seemed ok, with just a slight weep from the oil feed so I called it a night.

    The following day I checked and replaced the washers on the oil feed and run it up again ready for the maiden voyage unfortunately a leak from the water feed for the turbo then made itself know. So I shut it down and changed the clip before repeating.

    I was then ready to hit the road, it felt alright but a bit sluggish down low due to the timing being a bit off and then I lost the clutch another Doh! Moment, forgot to tighten the slave. Reminder always check everything over.

    After returning from its first run I had another go at setting the timing and tightened the slave cylinder. It was then time to do some proper running in and get the rings bedded in so taking the running it in hard ISH approach I hit the country lanes using second and third mostly taking it to 5k letting it rundown. I continued this over the next week with regular oil changes and increasing the revs gradually.

    With about 500 miles complete I picked myself up a new ECU and increased the boost after correctly setting the base fuel pressure and the car is performing as hoped.

    image_zpsvfsfkl3k.jpeg

    With a few weeks of constant use under its belt I was a bit apprehensive about posting anything online but its been revved to 7k now and has over a 1000 miles on it so hopefully Ill be alright.

    There is a weep from the sump which needs addressing on the next oil change and I want to get it checked over at a tuner to see what its running. But I think I can say Im happy with it after spending two weeks working away night and day.

    Now Ive said no more spending, but plans of how to fill my Christmas holiday refurbing the suspension are already formulating in my mind lol.

    Thanks for reading.
