Default LS400 Racecar/Track Car build

Well i am finishing up my ls400 build soon (i hope) and a few people suggested i start a build thread. So ill slowly try to post some pics here that i may have saved in my phone.

Anyways little background on me. I have had a ton of cars before. About 35+ most have been Japanese origin. Had Evo's Wrx's M5''s integras gs300 rx7 etc etc etc. Pretty much most import cars i have owned before. Had full out race cars before to awesome street cars. Hella flush cars and everything in between.

Some highlights of previous cars that i loved

Ls1 FD


Rocket Bunny Vert

Sr20 Van


Toyota Soarer (not sc300)


e34 m5 track car


Current Mr2

Anyways enough about all other cars. Ill start talking about the actual car in the build thread. Pretty much the goal of this car is to have a unique Ls400 that i can track. I had daily driven a couple of LS400's and love em so decided to build one. Trying to make it a fun car without being way too expensive.

Anyways once i knew i wanted to build an ls400 I started looking for a 95. I wanted obd1 for not having to worry about emissions along with getting the 95+ brakes. I kept looking and looking and couldn't find anything that i needed. A guy i knew at the time had a w58 swapped ls400. He was trying to sell it for way too much at the time . I thought about buying it but passed since i knew i could swap in a w58 into one way cheaper than he was trying to get. So fast forward to a few weeks later. He has the car for sale and its parked on the street.. He had the clutch replaced on the car and they left a bunch of the wiring loose. Chicago area gets hit with tons of rain and the car has a small flood. The carpet gets wet. So his insurance checks the car out and totals is because the cluster wont turn on. They figured the water messed up the electronics. (the wires that were left loose after the clutch job was why the cluster didn't work.) So i talk to the guy and make him buy the car back from the insurance company. Buy the car from him to cover his costs on it and a couple of hundred extra to go to a strip club lol.

So i get the car home. Driving open header in freezing cold weather.

Here is the car with my gf's daily 97 behind it

Ill continue with this tomorrow.. (i have to dig through my phone and find pics of all the progress)

So deleted lots of pics of this so excuse the ****ty quality pics that are posted. I primise picture quality will get better down the line lol

So I began the build by fully stripping the car Everything out. Sound deadening as well.

Doors get fully gutted

Started cutting up the hood. Lots of measuring and lots of time would go into this hood.

Tossed the wheels that i am planning on using on the car... A good 4inches of poke

Also bought some seats... They had civic rails and mounts on them. I modified the mounts to fit ls400 and bolted them in. I am pretty tall guy but i would have to be about 8ft tal to see out of these.

Curious to see the plans for the hood. I was just asking about the feasibility of a very similar center cutout in the weight reduction thread.

Keeping the engine stock. With all the weight reduction and the 5sp should be enough power to keep me happy with how it performs. If i need more power once i finish it ill blow up the 1uz and consider swaps like LS etc.

Default Stick with the 1UZ!

Lets get some R&D going with the 1UZ! I believe the 1UZ can take ALOT of Power and Abuse...The way I see it is the more attention the 1UZ gets, the more development is going to go in to them buy professionals and backyard engineers alike, the easier it will get for average people to realize the capability of this motor! ...Although, I do like how cheap and available the 1UZ is...not for long, now that people are putting them in 240s.

Oh, and what flare style are you feelin' on those grippers?

PS. LSx swap would be fantastic...obviously.

Not worth it in my opinion to mod the 1uz... if it had more aftermarket support than sure.As much as i love how it sounds and hate ls-x. Its hard to beat bang for the buck on LS-x. Flares progress shots will come soon.

Upgraded the lower ball joint and 95 brakes. Freshly rebuilt calipers as well. (don't mind the white over spray. After everything dried i wiped it off with paint thinner)

also decided to get some serious pads

Also brought over some HKS coils from Japan

For anyone who hasn't seen the inside of an LS all apart-its pretty much a jungle of wires lol

Also began making custom side skirts for the car. Took some spare mr2 side skirts and began extending them 15inches. Even with them extended they will fit with some gaps but from a distance will look good. (fiberglass cloth with resin)

Plans for header/exhaust? There are some things you can do to increase performance for <1k without going too crazy. The 1uz management runs it pig rich out of the box.

header i may make a custom one. not sure yet. may just leave the stock one. exhaust for sure will be building. just straight pipe with an x pipe. maybe throw in a resonator. Don't want to drop money into the engine besides maintenance. when chances are ill swap is out for something in the future.
