mgps13 build thread

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.

Finally got some time to get a few things done:



Went with a modified GTE oil pump from Powerhouse:


#1 oil pan prepped as follows: (soap/water, aluminum acid wash, soda blast, wash well again, WD40 on bare alumium surfaces to prevent oxidation, 500deg cermic paint for external surfaces only):

* Ferrea Beehive spring S2021 (x24)
