Well, it's been a while since i have updated (partly as i've been to busy to get much work done on it.)

IGNITION:
I have finally gotten around to sorting out the lack lustre performance of my ignition system. I got a new genuine rotor button and cap from work, and ordered a kbox overhaul kit. As my coil had high resistance, i have also fitted a MSD blaster 2 coil to boost the spark up a bit...



It's a little hard to see, i got a little bit excited and fitted it before taking any pics.

TYRES:
As i had utterly destroy my adrenalines, i got a set of KU36's in 205/50 r15 for the rear. Grip better in the dry than the adrenalines, but wet whether driving is another story all together (Did a review, sitting in the tyre section of the forum.)


There they are before fitting...


And there they are after 1,000km.

Make it triplets... check mine out

Yeah, but yours is so so clean, particularily compared to mine.

Well, it's been a hell of a long time since i updated the thread on my car. A couple of months ago the car started running rough, using a bit of coolant occasionally and blowing a bit of smoke. A couple of weeks later, while driving to a mates house, i geared down coming of the freeway, and there was a dull thud, then massive vibration through the whole car, and a horrible noise.

My first thoughts were something in the gearbox went or the clutch had destroyed itself, but i still had a working clutch and could select gears. so i slowed down, pulled over, and got the car towed to my mates place. Upon dropping the sump, i was met by something i never thought i would see:





So, not trusting any part of the bottom end from this motor, i have picked up a 50,000km old 4agze bottom end through a toyota employee. I decided that while i was at it, i would give the motor a bit of a freshen up. At the moment, the block is off getting cleaned, decked, bored and honed, so i don't have any pictures, but i have accumulated a few parts for the build. Thus far i have...




Later model GZE pistons, 50thou oversized.


An engine gasket kit with .8mm MLS headgasket


Head Studs







Supertech stainless steel, black nitrated racing valves. They are standard diameter, but have been back cut and undercut to help flow.
Also i have gotten a set of supertech double valve springs, titanium retainers, vitron seals and stainless spring bases.

As the GZE intake manifold it one of the worst designed manifolds ever made, and have some shocking casting flaws, i have begun to clean the runners etc up to help with flow. This picture has been taken early on, but you get the idea...



Hopefully, i will get a chance to keep this updated, but between organising and building the motor for the MR2, building an evil KE20 with a mate (build thread coming soon!!), and leaving toyota in a few weeks to another workshop, it might be a bit diffcult to do. Any thoughts, suggestions, or advise to do with the engine build would be welcomed.

Well, it has been a while since i have had a chance to go anywhere near a computer, but i have finally found a few minutes to update the build of my car.

I have finally had the block dipped, checked, decked, overbored and honed, checked and prepped the rods and crank, and assembled the bottom end. I ended up using ARP main studs and rod bolts in conjunction with ACL race series bearings.





I also had the head machined, checked, ported, and set up the double valve springs, and fitted a set of larger cams.







The motor is assembled to a long motor setup, and i have been working on a smaller clutched pulley for the SC12, which if turns out sucessful, i will explain and show how it is adapted to the snout, giving you a 95mm clutched pulley.





Due to the slightly bigger than planned rebuild, i will be running a motec M4 ecu with map sensor and air temp sensor, as i have played with too many area's to make it even remotely viable to run the factory ecu. I am installing a walbro fuel pump soon, and will retain the factory injectors for the run in tune, and depending on how the flow copes, i might upgrade to 550ish injectors.

very nice, reminds me when i rebult mine, it looked like that, for a lil while.. hope all goes well mate!!!

DOM

Cheers mate. I hope it goes well too. I'm interested to see how bad the factory intake manifold works, along with a few other things. I am really hesitant to let the engine bay look too different to stock with how many people with modified cars are getting epa'd at the moment.

Just a quick update:
I have finished 99% of the engine bay assembly, i have nutted out the new intercooler mounting, oil cooler and assmebled the rest of the engine bay.






Still to do:
* Install and setup water spray
* Fabricate air guide in bonnet for new cooler
* wire up motec, install and wire map sensor and air temp sensor
* convert injector loom for sequential injection
* Run in tune.

Looks good mate, nice car. I like the blue. Good job.

Just another quick update...

Photo of previously mentioned oil cooler setrup:

I know it is out of direct airflow, but i am kind of assuming wih the extra oil capacity, that will help with thermal management, as the car hasn't ever had overheating issues.
WHere have other adub owners put oil coolers on their car?? I was considering a SW20 PP style setup, but with the exhaust layout on my adub, it isn't much of an option. If it isn't effective enough, i will relocate it, or put a shroud on it to pick up air from under the car.


I have also deleted the AFM completely, and it has been replaced with a 3inch stainless pipe, which i have painted black, and welded a nut in to suit the air temp sensor. (please excuse the poor welding, the tig welder i had available to me was low on gas)


I have also started making up my patch looms to run the motec. As i am lucky enough to have the materials available to me, i am making my looms with tefzel wire, raychem heatshrink and deutsch DTM connectors. I have started making a main sensor loom, for my 3 bar delco map sensor, delco IAT sensor and my bosch coolant temp sensor. I have switched to the bosch sensor as it screws into the factory location, but as it is supplied by motec, it has a calibration code to put into the motec, which is easier than manually calibrating the factory sensor.
Also in the interest of a smooth idle and better driveability and light duty economy, i have made a loom to run sequential injection on the motor. It was a simple enough task, and i have put heatshrink over the terminals (as i have pinched the connectors for the new loom), and have folded them over and taped them back to the facotry loom, in case i ever return the car to stock.

I have to order some 4 core shielded wire to make a new loom to get my crank signals (i have been told that it is not uncommon to see misfiring due to system noise if i were to take the signal at the factory ecu).
