my 1980 Civic Turbo GSR swap... updated
 
2 Attachment(s)
This is the story of my 1980 Civic (2g) turbo gsr swap. I'm also chronicling this build on www.1stgencivic.com
All work is done by me.

After driving an '89 CRX for 8 years which can be found in some old threads here, I moved on to a '94 Civic EX Coupe. I swapped the motor for a GSR setup and then turbocharged it. It was pretty fast, but just did not handle anything near to what the CRX would do IMO. It was more of a cruise missle.

Well, I eventually came across this beaut from my boss for replacing a head gasket on his G60 Corrado.

I had those 16" Enkeis laying around and they seemed to fit the car so well I just had to 'buy' it.
Only after having taken delivery on the car did I find out that it actually already had a 1981 Accord engine and trans swap. It was suprisingly quick and very reminiscent of the handling of my CRX, vs the sluggish boat feeling of my 94. Unfortunately, the trans was shoddy and I couldn't take it in 5th gear due to the bad bearings.

Well, I wanted to drive this thing, and I was tired of my 94 that was damaged from end to end. So, what else but to perform a heart transplant, right?!!

Work on the swap began in mid-August 2009.
Unfortunately my picture taking has been a little hit and miss from time to time but I'm trying to get more where there are gaps.

Anywow, here are the early stages.
The chassis mount cups have already been fabricated here and the frame modified. I retained the stock location for the alternator by boxing out the rear of the driver's frame rail.
As you can see in the first pic, I had to notch the lower valence/core support as far forward as I could go. I have a perfect 1.5mm clearance between the turbo and the chassis :shock:

On to axles and stuff.

so here are my grassroots motorsports inspired axles. I know these look scary in the pics but they work, and if they end up being problematic, I now have prototypes and will farm them out to a driveline shop or something.

I had to combine GSR inboard axles with 1980 civic outboards. When installed the joint angles are a bit less than ideal due to motor placement limitations, but even with the wheels turned lock-to-lock, there is no binding of the joints and I've seen several b16 swaps that seem to work and they are dimensionally dealing with the same issues that I am.

These have since been ground down, cleaned up, and painted. But what you have here are the two shafts sleeve welded together via a 1/4 inch thick steel pipe.
Attachment 466201
Attachment 466202

to stay on the safe side, I'll be mostly avoiding clutch dumps and burnouts.
I'll get more pics with joints/boots and installed.

Looks like a killers swap, and some great work so far! What did you do with the front crossmember? Also, I noticed the Washington plates, where abouts are you?

Thanks for the encouragement. I'm not the greatest welder as far as aesthetics, but I can permanently stick some things together lol.

Well, there was a longitudinal brace for the front torque mount like the Accords and Odysseys. That won't be coming back. Hopefully it wasn't that important to chassis stiffness!

I've also got fender braces that I've incorporated you'll see, and I'm sure I'll eventually fabricate some strut braces as well.

Fitting wastegate and intercooler:

external wastegate needs to be rerouted to the side for clearance issues.
Attachment 466199

bumper and valence undergo some heavy plasma cutting to fit the intercooler, which inadvertently fits PERFECTLY. lol

So, a fuel injected turbocharged motor requires a lot of fuel.
I already had an in-tank 255 walbro from the 94 civic, and didn't wan't to have to buy an inline pump, so first I tried to fit the 94 tank. Wouldn't really work. I could have made it fit, but the parking brake cable was pinched, the tank sat much lower, soooo, let's modify some stuff!

I had to cut the top of the '80 fuel tank open like a sardine can, spot weld in the baffling out of the '94 tank, weld the top back on, cut a hole for the in-tank pump mount, weld that in, then finally pressure test everything and fix any pinhole leaks in my welds.

Here you can see the 'door' I had to cut plus the pump mount welded in.

Here is a peak at the baffling welded in the tank.

Dude that build is going to be a monster!! What a little sleeper that thing is going to be! Nice work! Do you have a way to drive the cable speedo or are you going to replace the insides? Also, didn't the front crossmember have radius rods connected to the control arms to locate them? Maybe the 2g Civic didn't have the same setup as I'm thinking about...

thanks!
I got the wire loom and heavy gauge wire from a local electronics shop as well as from Grainger. I also got the bulkhead connectors (which I haven't shown pics of yet) from www.mouser.com

Ah, the radius rods are functionally integrated into the sway bar. It's a dual purpose unit on these cars and the sway bar/radius rods mount with swaybar type bushings at the very front of the frame rails underneath.

As far as the gauges go, I'm not 100% sure how I'm going to tackle that one. But one idea is to retro the gauges from my '94 into the '80 instrument cluster. Room, however, will be an issue.

Pulled everything BACK out of the engine bay yet again to lay down some paint. Primed it with a 2K sealer then rattle can'd over it with satin black. (Black 2K topcoat and a bottle of flattener was just seemed like a waste of money. Anyways, now I can always fix nicks and dings with a $3 can of paint.)

Attachment 466154

After the black, I put everything BACK in. Ugggh.
You can also see the brake line work here. I DO NOT recommend messing with stainless hard line. Even the annealed stuff if nearly impossible to bend precisely and especially hard to flare (I broke my flare tool in the process). Hopefully they'll seal, but if not, I'll just replace with regular steel lines to get this thing on the road for now.

Here you can see where I've relocated the proportioning valve. I'll update with some pics of the hard lines under the cowling later.

Uh oh. What do we have here?

Ghetto paint booth. Works awesome. Negative pressure keeps all the dust from getting on all the things that would royally tick off my boss lol.

Attachment 466047

Booth coming down, car being revealed

Attachment 466048

More car

Attachment 466049

De-masked and drying. The car is now Porsche Guard's Red (LM3A) inside and out.
Please excuse all of the orange peel. This is my first attempt ever with spraying automotive paint. I've got about 5-6 full coats over most of the car so hopefully I will be able to do a good sand and polish once it's all cured.

Attachment 466050

Furnace filter taped to a box fan blowing OUT to create negative pressure on the booth. Don't ever try to paint a car red without a decent booth. The paint WILL GET EVERYWHERE PERIOD! It is the worst cleanup job you may ever have to do.

Attachment 466051

Guy-wires to keep the tent from collapsing inward on the car from the negative pressure. (Trust me it fell down twice. It doesn't take much negative pressure to create a lot of unwanted force when you have a couple hundred square feet of loose 'sail'.)

Attachment 466052

More to come!

I've done the makeshift paintbooth in a garage thing on a 1982 Accord. That was a huge pain in the ass. Plastic just wants to go everywhere (including on your car!) setup is a pain in the ass, teardown is a pain in the ass, the plastic goes everywhere and gets in the way. Nice work! That car is looking like a million bucks! Great color choice too!
