hey, in search of more information on this swap (92 SC300 auto to 1jz 5spd), I have come across much info, but many questions have come up.

here goes:

Can i use the 1jz auto ECU with a 5spd?
Do I need the soarer bellhousing for use with the R154 from a MKIII Supra?
Does the W58 just bolt on to the 1jz-gte?

I understand I need to lengthen the shifter on the MKIII R154 trans, are there any dealer parts that can do this, or can this be avoided in any way by using OEM parts?

if I get a 1jz from a MKIII Supra, will the wiring harness plug into the body harness of the SC?

Also, with a MKIII R154, what driveshaft will I have to use with the stock SC rear diff?

Also, is the hole for the master cylinder on the clutch pedal pre-drilled on the SC's, or do I have to make a template and drill it myself?

What clutch pedal/Master cylinder do I need to use for the 5spd swap? Will any MKIII/MKIV Supra Parts work?

I have searched for awhile, and there are the questions i've come up with.

Thanks in advance,
-Freddy

 

uhhh, I have found all your following question through research on the forum. Maybe you should look harder next time. I will be nice and answer them for you.

 

There's a hole in the firewall where the clutch pedal depresses the master cylinder for the clutch. i was wondering if there was already a hole for this, or does it have to be drilled, for the 5spd swap?

The entire r154 is different from the soarer to the supra?

 

YUP!.....

I'm a member of that forum already, but nobody posts.

Just the fact that one person says I can use a harness, and one person says I can't, means I have a problem. lol

I'm most likely going to get a 1jz from a supra, not a soarer. What needs to be done to plug into the harness?

 

Well, I wish you good luck on your project. The MKIII 1JZ mechanically is identical to the Soarer. But the harness has additional sensors plus the addition of the hydro fan. Depending on the year of the MKIII motorset the body plugs will be different. 87-88, 89, 90+ all have different body plugs. Here's some reference links to give you diagrams of all MKIII body plugs as well as Soarer body connectors.

thanks, anyone have any links to the factory service manuals for the sc's? That would be VERY helpful.


I'm used to working on Nissans, and i get alot of informations from these manuals.

Are there any Haynes or Chilton Manuals for these cars?
