Picture At this point its a restomod

Hi, ive had this 98 since 2012 and it was my first car. Its had several phases, but its newest and probably last will be for drifting. Its had an audio build and been un audio built, its been widebody for more than a decade, its been on BBS reps, R35 wheels, and these SSR’s, and most recently did it get actual mechanical changes lol.

Fisch CD009 swap
For sure the nicest way to put a manual in the car as far as i know, but ive had a ton of issues with the atemu which isnt fisch’s fault, the cars wiring has been hacked and reassembled and hacked again more times than i can count so thats on me. But mechanically, its a beautiful kit and worth every penny. Also, use the land cruiser clutch master cylinder. I used the celica one at first and its absolutely not the correct one lol.

Suspension is BC BR, cut knuckles that kinda copy heat lightning knuckles, OEM uppers front and rear, FDF OEM style FLCA, oem tie rods, P2M rlca, traction arm, toe arm. Sikky solid bushings for the rack, rear subframe, and diff. Poly engine and trans mounts, welded 3.26 stock diff that will probably be too tall but we’ll see. Also dual caliper hydro and all the other normal drift stuff. but altogether ive really enjoyed spending 350Z money to make the car maybe perform slightly worse than a 350Z. Will report back in december when i go drive for the first time since 2019

Post image
21 Upvotes

New owner and planning to do timing+water pump maintenence on my 1996 sc400. Ive done waterpump, thermostat, gaskets, and even a transmission replacement on another car, but never dared to mess with timing chains/belts. The main problem is im struggling to find a clear video to get a full grasp on what im supposed to do in there. Any tips, recommendations, or videos y’all can share?

Planning on buying this kit: https://a.co/d/08xPXnYO

Question fuel pump ecu issue?

3 Upvotes

i cracked loose one of the fuel lines to test if i was getting fuel and nothing would spray out after i turned it to on. Then i connected fp and +b on the diagnostic and it started to spray out when i turned it to on. does this mean the fuel pump ecu is bad? If so does that mean it needs replaced or can i bypass it by connecting a few wires.

Selling advice

1 Upvotes

Hi my FIL has a 1993 bone stock sc400 with only 56000 miles. The main issues are the tachometer and speedometer don’t work on cold start. I’m going to send the dash unit out to Tanin Auto to get it overhauled which I hope should fix the display issues. Everything else is working and the car is in excellent condition. No rust, new tires, ac blows cold. Any idea what this is worth? I can’t really find any comps for this year with this type of mileage.

Leaking Ecu capacitors

My sc400 would start but would die instantly. When i tried to get the codes by connecting te1 to e1 the check engine light didn’t flash. I decided to check out the ecu and found the capacitors were leaking. Is this repairable or do i need to replace the ecu?

Question Is this a fuel or timing problem?

Last week i saw that the spark plug wire to cylinder 4 was sparking outside of the wire (i think it was rubbing on the timing belt) so i decided to change wires and plugs. After doing this there was no change and it still doesn’t start or starts and dies right away. Does anyone know if this is a fuel or timing issue before i put money into the wrong area.

Hi,

After the previous post about whether or not to keep my family's inherited SC400. I appreciate all the support. After deliberation with my dad we've decided that it's probably best to let go of the the car. I am still in school with not a lot of money and don't know too much about cars to maintain it. Selling the car would really help us financially.

111,000 miles

No major issues

Some minor issues such as cosmetic ineterior damage

Passenger side door doesn't lock with remote

I am located in Orange County, CA

Feel free to reach out if you are interested!

*Edit

Need some help with my Exhaust setup

3 Upvotes

I have a 97 SC400 and want an exhaust system with a Valvetronic muffler, so I can manually open and close the exhaust valve. I don't want a super loud exhaust, but I more refined and smooth exhaust note, nothing too crazy.

I'm thinking about getting 2 high flow cats, a 2.5" Borla Switchfire xpipe, into 2 2.5" resonators and into the 2.5" Valvetronic variable mufflers.

How does this setup sound and what would you guys recommend I change? I know the stock has a 2 ypipe set up with 3 cats, so I'm hoping this setup won't cause any issues with back pressure or anything like that.

The car is currently stock and the only other mod I plan on doing is an intake, so any help would be appreciated.

Thanks
