Any more and the clutch won't hold. This winter I'm planning on going 6spd, 3.26/LSD rear, IS300 ignition, and hopefully build my FFIM. Then hopefully be ready to hit the dyno in the spring in hopes of some numbers in the 600's.

That's the plan at least, we'll see what real life has to say about that in the next few months...

Brandon, congrats on getting married! Now, it's time to get a GS, IS or some other Lexus for wifey! :)

I don't own a service manual for this car, so am not sure what the correct number is supposed to be. It's a stock N/A engine (high compression), stock cams, so I'd suspect the numbers to be high. More what I look for is consistency across the board, which is what I saw with the exception of the one being about 25psi less, which is good enough to let er buck in my world.

Just throwing out a small update here.

Car his been running phenomenally this year. However It is now officially parked for the winter and will be undergoing some changes. Other than coming out for some test drives here and there, I'm going to keep it garaged until I'm done with everything I want to do. I'm tired of driving it around half done. So here's the plans:

- IS300 COP ignition (purchased)
- Build a front facing TT style intake manifold (materials purchased)
- SC400 3.26 rear diff (purchased)
- LSD for rear diff
- 350z 6spd manual trans swap kit from SWAP1UZ (partially purchased, purchasing the rest in a month or so)
- 350z 6spd CD009 vintage transmission
- 350z Clutch/flywheel setup that can hold some decent power
- OEM 98 side skirts and basic lip kit for front and rear bumpers
- Paint
- Wheels
- Bring to DB Performance for tuning with 600+hp aspirations!

That's about it. This may take longer than just this winter to complete, but next time it's out and about it should be a different animal.

350z Trans to 2JZ adapter plate

350z trans huh? very interesting. y the 350z rout? cheaper than the v160 rout?

Halon Oct 24, 2012 08:27 PM

After the swap is all done, it should be a litlle cheaper than going V160. However I like the idea that once the swap is done, replacement trans are a fraction of the cost ($600 vs. $3k) and are easy to find sitting in junk yards everywhere.

SC430 rear diff from Aliga on here. Going to wire wheel off all the rust and coat it black.

Also seems like other than OEM, the only bushing options are solid ones, but I want this thing to still feel somewhat like a Lexus so no thanks. So we are making our own poly bushings for the diff ears. Depending on how that goes, we may also make poly bushings for the entire rear subframe as well. Will probably make them in 80A hardness, although me personally I'd rather have something closer to the 65A range.


Cleaned up the front calipers with some Rustoleum. Before and after shots

Brandon, you're making some serious progress brother! Nice job with the TT caliper clean up!

Halon Oct 25, 2012 08:19 PM

Thanks :) things happen a little slower now that I'm married, but I keep just slowing buying piece after piece, helps it all fly under the radar a little better !!

LOL, It's good to know that I'm not the only that does this!:thumbup:

Managed to squeeze in about 2hrs of work on her yesterday. Result is the rear subframe sitting on the floor :)

i just purchased a sc300 92 5spd 223k on odo it runs great looking to do the same basic upgrades as you. brakes etc.. still trying to decide between a 1j or 2j but i really want to make sure cars running good first but your car is clean bro...

Little bit more done today. Got all connections/etc. disconnected so the rear subframe is completely out. Driveshaft removed. Mid portion of exhaust removed. Rear ABS sensor wiring removed (For good). Muffler heat shields removed. Just lots of little misc crap removed basically.

With the underside fairly exposed at this point, I was actually pleasantly surprised by how little rust there was considering this thing has over 160k miles. Mainly just in spots where the rusty fasteners were, are little spots of rust. However I was inspired by someone elses project where they cleaned up the underside of their car.

I don't have the skills or patience to go to they level they didl, but still, makes me want to get the underside of the car looking nice too. So I will be trying to take my time and replace anything rusty (fasteners, clamps, lines, etc). Coat things like control arms, subframe, diff, etc so they look like new again. Replacing bushings with poly ones where it matters, and probably just OEM in some spots to keep it feeling like a Lexus. And may consider sanding and putting some sort of undercarriage coating, but not sure yet if I'll take it to that level.

Here's how I left it tonight, as well as some shots of the underside of the car showing the small areas of rust around fasteners.

Man, I can't believe that I have never read this thread before now. This is some good stuff for a N/A build, I must say. Anytime thre is a build, things come up and we come together on here to help figure things out. Glad you have continuing your work on her and getting it done correctly. Can you supply more pictures of the hangar rack for the fuel hanger on using two pumps? I might be in the progress of doing this but using 2 TT pumps. Trying to get some ideas. Your build looks great and now I will be following this till it is completed. If 600 is your goal the 350 z tranny should do the trick. If not go R154!
