ARP flywheel bolts
Turbo oil drain flange on sump
ARP head studs and 4A-GZE 8.9 CR slugs
ARP head stud protrusion. This is why some need to shave one of the studs as it fouls the distributor shaft. Obviously not this one as i took photo of the wrong side.
Considered leaving the timing belt cover off but put it back on to be safe.
Last shot before turbo conversion the next day. Notice the oil drain line is only ziptied near the strut tower.
The next day, after running the engine for a day and ensuring the rebuild was successful, turbo conversion was started. Oil sandwich adapter went in first. Only one out of four outlets was used.
HKS copy cast iron manifold with gasket cut out from a soda can. Cheap and refreshing, indeed.
The very minimum space at the back of the turbo with downpipe flange off. Gotta move some wiring to protect them from the heat.
Oil lines plugged in and this is the final shot of the day.
The next day which was yesterday, exhaust was fully redone. The initial plan was only to fabricate the downpipe and connect it to the existing exhaust but after quick reconsider, decided to ditch the whole system and put 2-inch pipes front to rear. Only 2-inch? Well, the turbo downpipe flange output is that diameter, i'm merely following. No use in going bigger, yes? The flexible joint was welded to the downpipe and only one tiny muffler was used. The rest of it was 2-inch piping and elbow joints to allow going over-axle. Oxygen sensor bung was installed on the same location as the original piping. Didn't take many photos that day, sorry.
Finally, just today, i installed an SPST switch on the bootloader jumper header on my Megasquirt. I did this to ease flashing firmwares later without having to open the MS case anymore. I'm currently focusing on finding the correct values to go into the kpafactor and barofactor inc files as i'm going to use the 4A-GZE map sensor which is not directly supported by the original MS1-Extra firmware i'm using.
