Default 94 SC300 1JZ Build Thread

So here's my build thread for my 94' SC300. I bought the car for $500 with a clean title. This will be a drift project and my power goal is 500hp at the wheels and still be a daily

Shopping list:

1JZ from a Soarer
R154 5 Speed Transmission
264 Cams
AEM FIC or Emanage Ultimate (Still haven't decided)
2MM head gasket
6 puck ACT clutch
GT35R single kit from Supramania
650CC injectors w/ TT resistor pack
Still haven't decided on coils
17x8 Front and 17x9 Work Equips
LSD
Hopefully some 5Zigen Fireballs
TT Denso Fuel Pump

I've been able to remove the cylinder head, stock twin turbos, and now I'm working on the wiring harness. I'll post some pictures up as soon as I can. The twins were a pain in the *** to remove. I plan on sending the block to get machined, stripping the interior, and saving up for some gaskets.

I picked up an R154 for $300 without a bellhousing and still need to sell my A340 that came with the engine. I have a thread up with these items for sale and I'll be selling my stock 2JZ and tranny when they get pulled.

that 1J looks really clean! You'll have to post pictures of the inside once you tear it down!

You can't really say no to a $500 Lexus anything, especially an SC. Looking good.

I honestly didn't think it was too bad. The interior is shot but the A/C, moon roof, and most of the electronics work.

The motor is in good shape but the previous owner used some cheap gasket goo.

don't use a 2mm HG, just get a tt one or the stock 1jzgte HG.

Act clutches are very harsh, heavy , noisy and don't last longer.

Southbend makes some great clutches.

Thanks quick, do you recommend using the 2JZGTE gasket? I know some of the holes are smaller but on supraforums a lot of mkiii guys seem to run those. I thought about 2mm since the one I pulled was that thick.

Yes ! I have always used the gte hg on the 1jzs since the stock 1jz hg can't be found easily now days.

2jzgte all the way, works great and it's multi layers just like the 1jzgte HG.

You are using some of the same mods that I have. Which cams are you using? BC or HKS?

I must disagree with quick on those act clutches. Im currently running a act clutch in my r154 and love it, not harsh at all, pedal feels just like oem and no noise. Although mine is a hd plate with a ss disk, not a 6 puck

What act clutch do you run before you disagree with me?

All the act have dual diaphram so it's heavy when you go with a puck clutch.

With HD the pedals does not feel stock you can ask anyone that run act clutch on jz.

Depending on what clutch you get it will shatter unless you have "the special perfect clutch"

This is the clutch i had on last 5 setups
http://www.advancedclutch.com/produc...d_id=8795#8795

I ran act on all my R145 for the past 5 years, we are talking about 6 puck not full face.


Search on here and you will see that i have always ran act.

I didn't say that it doesn't work act clutches work great once you start making good power , the only clutches that they offer are HD PP with puck disc so it will chatter , harsh engagement etc..

Have you ever had crankwalk with act clutch? well i did HD pressure caused it.

I am not here to BS yall, This is the information that i had gathered from my own mistakes and i'm sharing with yall so take it for what it's worth!

Do you know if the 2JZ gasket kits would work?
