mgps13 build thread

[mgps13]

Actually I am cheating, this is from back in the day. I was waiting for the thread to open up so I can catch up to current. There is a duplicate thread on supra forums because of the JZ, but i figured since I am starting to focus more on the chassis that I should be over here as well.

Ok so here it goes:

[mgps13]

Valve seals, Titan 264 cams, knock off Greddy plenum (get to that again later), treadstone t4 manifold, T04S (because i had one ), Billet Tbelt tensioner bracket




powder coated crossmembers and control arms. fabricated a "Power Brace", Energy Suspension full kit, TEIN Springs, 8AN fuel lines, custom fuel pump hanger (running 1 aeromotive stealth for now, but I should be able to fit 3 on the hanger if needed)




Ran the setup for 10K or so, first with a Spec clutch and then with an ACT setup. Then one day on a high rpm shift into 3rd:
THRUST WASHER FAILURE

[mgps13]

After the thrust bearing failure on the aristo bottom end I stole the heart of a lexus for a block and crank. The last setup didnt look too bad, but I did not want to risk it. At a minimum it would have required adding material to the crankshaft thrust surface. I will use the NA block and crank for the base of my build up.


Check out that Tbelt^, this dude was running on faith for sure


So the lower end will go as follows:
* Complete proper cleaning (all oil gallery balls removed)
* ARP main stud kit
* Line hone
* Bored (20 over/86.5mm)
* Manley I beams
* CP pistons (9:1 compression, upgraded wristpins)
* Modified oem oil pump

After the thrust washer failure I decided to go for less clamping force which meant a multi-disk clutch. Ended up going with an exedy twin disk intended for the 1jz.


Tore down the stock valve train.


Soda blasted the head to get it ready for the build up:






My kid is going to handle the valve lashing for me:


The head build up will include:
* Toyota Shimless Buckets 13751-46200 5.40mm (24)
* Ferrea Comp Plus Valve F1498P (x12)
* Ferrea Comp Plus Valve F1499P (x12)
* Ferrea Beehive spring S2021 (x24)
* Ferrea Titanium Retainer E12029 (x24)
* Ferrea Valve Guide VG1035 (x12)
* Ferrea Valve Guide VG1034 (x12)

Full gasket kit, modified oil pump, ARP head studs


Sport 2000: The custom ecu harness I fabbed has a breakout near the ecu so I can switch between different units with just 6 Deutsch connectors. ( I will show all that when I get around to installing everything again)


(MR2 shimless bucket conversion, machined billet locks) vs (stock lifter, shim / stock locks)

Ok so this is a little vague, but it might help others who are considering fabricating an ECU harness. I will elaborate on this more once I get everything back together.

Essentially I created a new harness from scratch using new Toyota and Deutsch connectors wrapped in Techflex braided wire cover. I also used MIL spec shielded wire for the crank, cam, and knock sensors. The harness has a breakout near the ECU that allows you to switch between ecus without unplugging anything else. I also added breakouts for an Apexi AVCr and a Zeitronix wideband controller.

The pics below are from the planning of the harness, I will post some pictures of the actual harness when I pull it out of the car again. I ran the harness for about 1500 miles with good results so far.

Some notes:
Toyota Color: Wire color/pin from stock Aristo Ecu harness
Engine Color: Wire color in my fabricated harness
Haltech Color: Sport 2000 flying lead harness wire color

NOTE: Ignore the pin numbers in the second picture. The tables shown in the bottom image is how I actually laid the harness out.
