Time Attack / Street LS1 FC Build
« on: May 02, 2011, 04:20:16 PM »
Hey guys, I bought this car last fall from a forum member down in Kentucky.  Figured I'd toss my build thread from another forum over here to see what your thoughts / advice might be for the car. 

:wavey:

As some of you guys already know, I ended up picking up the FC from Kentucky last weekend... if you aren't familiar with the car, it's an LS-1 swapped 2nd gen RX-7 with light modifications to the suspension and motor:

Factory Options:
-Sunroof
-Leather
-Power locks
-Power windows

Exterior Modifications:
Aluminum hood

Performance:
-Stock LS1 w/ Hinson mounting kit
-JTR cooling kit w/ Volvo fan
-Custom CAI
- Supra fuel pump
- Corvette fuel filter/regulator
- Descreened MAF
-BrianCWS6 ported throttle body
- !EGR
- eBay shorty headers
-2.5” y-pipe to single 3” exhaust with Flo-pro twister muffler
-LS6 intake
-Thunder Racing ported MAF ends

Suspension/Chassis:
-KYB AGX's with Racing Beat springs
-Racing Beat swaybars
-Poly transmission mount

Drivetrain:
-Stock T56
-Series 4 Turbo II rear diff
-Hurst shifter

Electronics:
-Scangauge

Initial driving impressions are that this car is absolutely insane, spins 245's all the way through third gear :)

On the way back from Kentucky the rear end started howling, which the seller told me about prior to purchasing.  We did an emergency pit stop in the ghetto of Louisville at an autozone at midnight and did a diff flush, although it didn't fix the problem. 

Upon full inspection of the car at my friend's shop in Detroit, we found that the rear swaybar endlinks were snapped, some of the wiring was a mess, etc. tons of random things that are easy to fix but should have been done right when the swap took place. 

The good news was that the motor is completely healthy, and the recently rebuilt trans shifts great and makes absolutely no noise.

I somewhat feel that I paid too much for the car and should have done it myself from scratch, but overall it's a very solid car with tons of potential and a good head start with the swap being done!

Some parts on the way:







Also, my friend Nick and I have already installed solid subframe, diff, and toe eliminator bushings in the rear end, and have the lsd torn apart awaiting all new bearings and seals.  The car should be back on the road by the weekend and starting to feel like a race car!

Still in pieces, but the car is coming along slowly.  Should have the rear end rebuilt and back in the car by monday. 

In the meantime, ChaserAero has been cool enough to hook these parts up at cost for me via a small sponsorship:















Coilovers should be here on monday, endlinks and almost all of the bushings are already installed.  :wavey:

Relocated heater hoses, tucked wiring, Aerocatch hoodlatches installed, coilovers installed, hood installed, cooling panel installed.

Also ordered a camo vinyl wrap for the engine covers, and some waaay nicer parts to make a new intake (which will also be camo, I'm going for a jdm redneck theme here).

Pics for those who don't like to read:

Engine covers are almost done, relocated some wiring and such so that they sit flush onto the valve covers :)



Also threw some stickers on my cracked cooling panel, I like the holographic ones :)



Also finished the intake for the most part, all of the couplers are high pressure silicone and I'm running a 7'' cf k&n.  Just needs an airbox fabbed up to keep temps down.

So I got a LOT done today :)

      Here's the scoop on the wheels, the rears are actually fitting decently on the stock quarters.  Nice roll and pull might save me from cutting up the rear fenders :beerchug:     The fronts, however, are poking and 1/2 inch on the outside and pressing on the coilovers on the inside... I'm gonna try a 5mm spacer tomorrow and see if they clear the suspension.

Onto the pics :)

So I started fitting the wheels and bodywork, ran into a couple speedbumps. 

First I was having some interference between the wheel and coilover, which I remedied with a 5mm spacer (better hubcentric ones with studs are on the way).

 Check out this pic after the spacer went on, the lip of the wheel is actually INSIDE the space between the bottom spring coils lol



Now that the spacers are on the front, the front fenders aren't wide enough :( under any kind of compression the tires will murder the fiberglass arches.  I might make some sort of metal fender extensions to fix this, might look pretty cool too :)

Anyway here's some pics and a walkaround vid.

18x10 all the way around...... TUCKED!


Well.. sort of.  Did you know that you can flare a fiberglass fender?  You can't really, but I tried it anyway with mild success!  The fenders are now about 1/2 wider and twice as shitty looking!  :) 















I drove the car more than 10 feet for the first time in months today, verrrrrry happy with the way everything is going.  Although, now that there is serious rubber underneath it the clutch is getting seriously overpowered.

Over the next month the car will get:

Rear overfenders installed + spacers

Clutch, flywheel, slave cyl etc.

Power steering rack, pump, lines, etc.

Header wrap

Motor mounts

Bigger radiator

Also,

I got these solid rubber diff mounts (to replace my delrin mounts). 



Too much solid mounting in the drivetrain is creating a lot of noise and vibration, these should soak up some and still be nice and firm.

More to come, I'm selling stock parts so it'll be time for more new stuff soon!

Installed lights and steering wheel, deleted the rear wiper and pump stuff.

The car is about to go on Jackstands for a long time for installing the following:

Clutch/Flywheel/Slave cylinder
Power steering pump, rack, custom lines
Header wrap
Engine mounts
Diff mounts
Side skirts
Delete the rear swaybar

... probably more that I can't think of, shits gonna be sexy though.
