ErnGotti's RB20 swapped 91 coupe

Okay, so here goes:

Things the car came with: 3" turbo-back catless stainless eBay exhaust
Walbro 255lph fuel pump
GReddy Turbo Timer
Really nice white inlet filter
eBay Electric Fans
Rear 1995 240SX 5-lug upgrade
Skyline Gaugecluster Tach
Autometer SuperTach II
Autometer ProComp Boost & Oil Pressure gauges

Things I've fixed: Installed a Z32 master cylinder to fix reservoir leak
Replaced 5 lug rear calipers with 4-lug ones (they were
seized and the e-brake cable wasn't compatible)
Replaced Sending Unit and O-ring gasket to stop gas leak
Had front wheels/tires balanced
Replaced rear tires with Falken FK451 GR-Betas
Installed Aluminum vent gauge pod holder
Replaced a couple vacuum lines
Installed NGK Iridium Plugs (heat range 6 - coldest available
for that plug size)
Installed a new battery
Installed a coolant catch tank
Replaced upper radiator hose
Replaced missing lug nuts/studs
Replaced rear pads/rotors
Repaired clutch lines (they were installed backwards)
Bled clutch/brakes
Installed bolt to secure right rear lower control arm
New wipers

Problems I know of: Water pump leak
Off-key idle
Weak clutch/Very bad throw-out bearing
Horrible front brakes (caliper bolts are seized)
HVAC doesn't work
Radio doesn't work (everything needs to be manually
wired with a switch - speakers too)
Seats are shot
Shifter pops out of place & spews grease evertime I start
it
Tach doesn't work
Speedo doesn't work
Oil Pressure gauge doesn't work
Out of alignment
No power steering pump
Lower left clunk (either SMIC or ball joint)
Needs 5-lug front upgrade
No glove box
Rusty trunk
No hood latch
Headlights need to be manually retracted (but they come
up on their own...?)
Loose Carrier Bearing bolt
Loose main wire to fusebox
Loose lighting wire to gauge cluster
Frequent overheating due to leak
Washer fluid reservoir overlows onto the lawn
Sending Unit cover is mangled
Neutral safety switch either isn't working or isn't hooked
up
Reverse lights won't come on
It has electric seatbelts!!! I hate 'em
Paint was done by Maaco and traps dirt
Doors were replaced after an accident but the
handles/barrels weren't swapped, so I can't lock the doors

Things I still need to put in: Racing seats
95 240sx E-brake handle/cable
Autometer tach adapter (ECU puts out AC, tach
needs DC)
Entire lower dashboard/glovebox

Springtime plans: 17x8 gunmetal wheels (either TSW
Estorils or Ikon Monacos
Aluminum radiator
Lighter battery with isolation kit (behind passenger seat)
FMIC
KYB AGX struts
Tenzo-R springs
Stock 240SX/S13 LSD
Front 5-lug upgrade
Install e-brake/rear calipers
Drilled/slotted rotors w/ ceramic pads
Fab a B-Pillar & floor cross-beam
Harnesses
Remove rear seat
Hook up radio/spakers/system
Hook up tach
Misc. Bolt tightening
Maybe an enamel rattle can paint job (just for now - real
paint job will come when I have pieced together a front end
and rear end)

The Story: The car was purchased from auction for $400.00 about 4 years ago. The guy who bought it didn't want to fix the automatic transmission problems the car was having and sold it to someone who sold it to someone who sold it to Drew. Drew did the manual swap, but got angry once he realized nothing was working in the car. He started cutting wires...messing things up further. He parked it and it sat for 2 years. Scotty bought it December 2006, and worked with the guy Don who did the actual swap. They got the car running again, and Scotty started modifying the car while Don was repairing it. Scotty stopped working on the car, Don stopped working on the car. I bought it off Scotty August 2007 for what he paid for it: $3000.00. The inspection was up in May 2005. I am the first person to drive it in 3 years. And I have come to the full realization that this was not the best swap for this car. I welcome any suggestions and help from people who have 240's with RB20/25's.

Anyone know where I can get an underdrive pulley?

well its a start but, its gonna need some work.
It's very rough around the edges, like the interior and that HUGE tach.
And that turbo badge is completely out of place IMO

hahah I know! The badge is horrible but hopefully (eventually, but no promises) I'll get an R32 rear end on it and have the OEM Skyline & GTS-T badges. That Porsche duplicate cost $4.00 at Autozone...and I did it because no one beliveed me on the streets. The engine doesn't produce boost in neutral, so no BOV. I don't like lying about things. People who say they have this, that and the other thing bother me. Even if it's in their garage and they're putting it on tomorrow, it's not in there now. I don't want people to think I have a KA24E with a goofy exhaust.

I am reading up on the RB section. Incredibly informative.

I have some student loans and income taxes coming soon so that's when the car will be better than it is now. BUT! hahah the woman is mad at me because I'd rather spend the money on the car than the wedding (it's in June 2008) !! What true car fan wouldn't?!?

You know, you're not the first to say that to me. How come I hear that? Is it because it is ugly or too hard to do?

How does it run?

Lot's of wiring issues. I hope your well rounded in electrical and can run a voltmeter. I got an rb20 hatch, let me know if you need some help.

message left on rb faq about your wipers. also who did you harness or did you do your own? if so i can give links to rb wiring info. also the s13 tach and speedos dont work at all with the rb it looks like you have an rb tach in your cluster so the tach signal is probably not wired up. anyways if you need any help i can help as much as i can but it seems like the rb20 swap was just not done properly. also if your in need of a lsd diff i have a 6 bolt j30 diff for sale that swaps in with no issues, you just have to swap rear covers from your s13 diff to this diff.

Yeah dude, I would wetsand that paint and wax it so it looks new.
Fix up that wiring.
Detail the motor bay.
remove any unnecessary parts.
Lower the car and get good wheels and tires.

To me that would make the car good for now.
R32 etc conversions are too ____________.

The swap was done 3 times...same engine, same car. I do need a diagram bad. I'm familiar with volmeters but it sounds like I might as well marry one instead. lol

After reading all your guys/ posts on here I'm actually thinking of getting ANOTHER 240 and starting over. Taking this engine and putting it in that car. Then selling this one for parts. Body is not good, undercarriage is not great, lines need replacing..blah blah blah. I can do it, but sometimes I just get so frustrated. We've all been there I'm sure


Oh, and how much for the rear diff? I am in desperate need. I don't know about them so what do you mean "rear covers"? The casing?

Springtime it will get paint attention. Trunk is rusty and bent so it doesn't like to open always, so I need a new one of those.

I can't hide the wiring just yet until I get everything working. That wiring diagram would be a blessing.

Intake manifold/FMIC/Aluminum radiator/relocating battery will clean up the engine bay pretty well I hope.

Tell me what you guys think: On a budget, I'm thinking KYB AGX struts and Tenzo R springs for now. My ultimate goal is Tein SS w/ EDFC, but that is way out of my price range right now.
