Godzilla swapped 240sx - my primary hobby/project

Recommended Posts

Figured I'd post a build thread of what keeps my car audio hobby from getting too ridiculous. I’m building an S13 coupe with an rb26 mainly for street/road race, some drifting most likely as well. I want it to be well rounded, not just a ton of power that I can’t use.

A pic of where the project is at right now in case you don't have the attention span to scroll through my 10000 pix:


Short summary of plans:

Full suspension

17” 275s or larger up front and 315s in rear

Carbon fiber Zg fender flares

Silvia front end/Carbon fiber hood

Rb26 (first stage of build going for around 400whp with stock twins, later I will upgrade turbo and valvetrain and go for 600whp)

Kaaz 1.5 way (hopefully selling and going with an s15 helical with q45 axles instead)

Detailed list (not a complete list of things I have or plan on getting, but has most of the stuff that will be happening this summer):


HUD dash w/ working hud

Racing seats (not purchased yet)

Harness bar (not completed yet)

5 point harnesses (not purchased yet)

Seam welded

Fender braces (not completed yet)

Misc chassis bracing (not completed yet)

Silvia front end conversion with triple projector headlights

HIDs (not purchased yet)

Carbon fiber hood (not purchased yet) – will leave unpainted

Carbon fiber fender flares (not purchased yet) – will leave unpainted

Origin Tail Lights – planning on blacking them out a bit

Mostly full interior minus rear seats

Modified power brace

Aluminum Triangulated strut tower bar (not built yet)

Some sort of light weight replacement for bumper brace, most likely an aluminum bar (not built yet)

Misc. weight reduction


Tein HE front coils

Tein HA rear coils(z32)

Z32 up rights aluminum with poly bushings

JUST Modded Dream fab front drift spindles s13

S14 control arms boxed with new moog ball joints

tein inner tie rods with SPL Parts outers

circuit sports T/C rods

Project Silvia RUCAS

adjustable toe rods

adjustable traction rods

5 lug ichiba fronts with long studs, z32 rear

rear s13 subframe with aluminum solid bushings installed


z32 30mm alum. front calipers

ebc 12.25" vr4 front rotors

project MU B-force Pads

Z32 rear calipers with power slot rotors

I have 3 stages planned for the engine, stage 1 is obviously get it running lol, stage 2 is turbo, stage 3 is valvetrain.

Engine - "Stage 1":

Wiseco Forged Pistons

Eagle Rods with ARP bolts

ACL Race Main bearings

ACL Race Rod bearings

ARP Head Studs

Cometic MLS head gasket

N1 Oil Pump

N1 Water pump

Nismo Thermostat

Raw6 Intake manifold (copy of greddy) (have not purchased yet)

1150cc fuel injectors (have not purchased yet) (sizing for 600whp on e85)

Nismo Fuel Pressure Regulator (have not purchased yet)

Spitfire coil packs (have not purchased yet)

adjustable cam gears (have not purchased yet)

Greddy oil filter relocation block with built in oil cooler thermostat

Twin Z32 300zx N62 Mass airflow sensors

ISIS 3" Straight pipe

ECU: Apexi Power FC with hand commander and boost control kit (currently for sale, thinking of going haltech instead)

Innovative motorsports wideband

Engine will have stock valvetrain and stock twin turbos for this stage of the build.

Output goal is around 400whp

Engine - "Stage 2": (most likely next year):

Big single turbo (probably a Garrett GT35R)

twin scroll exhaust manifold of some sort

Divorced but recirculated waste gate pipe (recirculated to end of downpipe)

Power goal - 550-600whp

Engine - "Stage 3"::

ETA TBD (sometime after stage 2, depends largely on $$$)

Tomei pon cams type B

Aftermarket timing belt

valve springs and retainers

power goals will be the same 550-600whp except looking for 9,000+rpm rev limit


RB25 transmission with short-throw shifter

ACT clutch and lightweight flywheel

McKiney engine and trans mounts

Aluminum driveshaft

Kaaz 2way LSD (for sale, looking for S15 helical w/ q45 axels instead…if I end up staying with the KAAZ I’ll convert it to 1.5way)

The donor car. Cylinder 6 ringlands went to hell 15 minutes from the guy’s house due to what I figure was a bad tune and/or bad gas.

There’s your problem:


The chassis. Fairly clean 1993 pearl white coupe. Pulled stock KA24 and swapped it into the grey hatchback the rb26 came out of:



Reverse rake!


New exhaust Isis 3” straight pipe:


Picked these up cheap so that I can drive the car before having to spend $2500+/- on tires/wheels/fender flares:


First wave of parts from rawbrokerage.com!:

ARP head studs and ACL main and rod bearings


Nismo thermostat


Wiseco Forged Pistons


Eagle rods with ARP rod bolts


Greddy oil cooler adapter with thermostat

Drilling out the rear of the strut tower (was beat up…looked like a spring broke or something)

Replaced the section in the strut tower


Stripping undercoating




Cut out crushed section of frame rail

That's fn sick.

My buddy who has a turbo 350z has an r33 that he rb26 swapped with a bw s372. Change that oil pump quick, I think he had the car with a bone stock motor for 3 months before it crapped out and lost all pressure.

Seeing all your work makes me realize I'd rather cut and weld over fiberglassing wood and boxes any day haha, this shit is so time consuming >.>

What's your end power you have in mind?

I didn't see you drifting or just making a street car or?

Those 240sx's make a great platform to build on... My cousin built one when he was overseas in Okinawa when my uncle was stationed there for the marine Corps... He said it was fast as hell and EASY to find parts for

Lovez me a coupe!!! Looks like its gonna be a nice ride when you get it on the road.

What are your plans for the audio dept? I have an S13 coupe as well (silvia nose/sr20swap). The trunk doesnt give you many options but I managed to get some bumps out of it.
