Starting build #2 , I WANT 500 RWHP...

[87turbosupra]

So I've had my 87' "Burgundy" for about 7 years. It had been sitting for the past 4 years now in my garage with a blown MHG. I'm finally ready to do this thing right. I've just got the engine out and disassembled. Sent to the machine shop last week and waiting for the go ahead on what size pistons, bearings, MHG to use. I'm going to have the entire rotating assembly balanced with forged pistons and rods, also go through the head and have a valve job done. So far I have lex afm, 550's, safc 2, AFPR, walbro, profec-b. I really want to reach 500rwhp and have piece of mind the engine will hold up. My current dilema is what turbo/manifold setup to go with. I saw a guy on 7mpower with a t4 adapter on his stock manifold and was wandering how well that would actually work.

here's some current pics

A GT35r or billet precision 6265 would do the trick. I made 515 at 28psi on my HTA billet 62mm with just a bone stock used JDM engine and SAFC and supporting mods. However on pump and meth it makes 435rwhp, which is pretty good on the street and has been super reliable for over a year of hard driving at that power.

So I just got a call from the machine shop, he said he broke the coolant pipe banjo bolt on the back of the head and damaged the threads, has anyone
run into this. Any suggestions for fixes other than a new head.

Yep been there done that....

Used this to remove the dead part>

I have no direct experience with the turbo yet, but I'm really thinking about going with the borg warner S300SX 83/75. Very similar to the GT35R in spool, but costs less and flows more at higher boost levels. See my build thread for some discussion on that series turbo. Good luck!

 

[87turbosupra]

Were your threads damaged or were you able to just remove the damaged pieces. This sucks I was ready to start ordering parts
but if this guys tells me the head is bad I'm gonna cry that was my last spare one.

Using that tool the threads were ok, don't know what he's tried so far he might have killed the threads if he's used a conventional easy out as they tend to expand the broken part....

 

[87turbosupra]

Yeah that's probably what happened. I think I'm gonna end up welding a small pipe and add a T for the coolant lines.
Oh damn, I forgot to ask. where the hell can I get a torque plate from for the block, there are some on ebay, but does
anyone have experience with those or anyone willing to sell there's??????

Check this out, wonder if its worth the money over the stock manifold. I looked at that billet precision turbo and it looks NICE. mmm I love turbos.

So have some updates. I had a machine shop custom machine a larger coolant banjo bolt for the back of the cylinder head
that broke and they tapped the threads larger in the head, it came out perfect. I just ordered some goodies.
- .020 over CP forged pistons
- Eagle rods
- Fidanza light weight flywheel
- stage 3 Spec clutch
- Clevitte bearings
- Torque plate ( really sucked getting this, but I live in CO and nobody has one)
Still deciding on which turbo, Billet Precision 6265 or 6765.

So I'm working on the transmission while I wait for engine parts to arrive. Here's some tear down pics of the tranny. Does anyone know of a rebuild kit for the r154, I couldn't find a site for mdc motor sports anymore.

Here's a good shot of one worn out synchro.

For those that haven't seen it before or are otherwise unfamiliar....

The brass ring has pointed ends, where you see his are worn down. That is the grinding in the transmission when you grind it. The syncro part is the underside which is threaded to match the speeds. The pointed teeth worn down on the top are the clutching teeth that hold the transmission in gear. When they are worn, the trans will pop out of gear.

Sorry, just realized I posted this thread in the wrong area, how do I move this to the "Builds" thread.

You can't

 

[87turbosupra]

Have some update pictures. Finally got the parts I ordered and sent them to the machine shop.
I had the cylinders bored .020 over, decked the block, new oil pump drive shaft bearings, all new
freeze plugs, crankshaft grinded and balanced, cylinder head milled, new valve stem seals and
complete valve job. Now I'm ready to assemble the engine. Next will be the drift motion 67mm
turbo kit.

 

[j3r3my]

builds looking nice but you should touch the rods to much they'll get surface rust from the acids/oils from your skin,just a heads up for ya!

 

[IBoughtASupra]

Did you balance the rods and pistons? Just incase you don't know, do not use the oil pan gasket that came with the kit, use Toyota FIPG since it is the best silicone I have used.

Your ambitions deserve a renaissance. Time to truly rethink the traditional piggyback system, and consider a standalone that will in almost all instance give you that "piece of mind".
I know I have.
Some will argue that you don't need one, but I'm old enough to remember computing technology (286, and 386) in the '80 and early 90's. The OEM computer is from that era and it performs as expected. So immediately, it's at a detriment to modern ECU's, and even the latter to it's gen' such as the JZ's.

 

[87turbosupra]

They are brand new CP pistons and eagle rods. I didn't think they needed balancing, they are supposedly balanced
within 1 gram of each otherand yeah that cork oil pan gasket is going in the trash I learned that the first time
I resealed the oil pan.

Yeah I'm definitely not staying with the SAFC 2 anymore. Haven't decided which standalone to go with, AEM or Stinger.
I plan on getting rid of the MAF setup for a MAP sensor. $$$$$$$$$$$$$
