If your initial thoughts are $15,000 then it will ultimately work out to $25,000.

That's just the way it is.

^^^ Bingo!

I'd for sure upgrade a '74. Get a newer car for fwy cruising or long trips. I had a Boxster S on lease for 3 years and returned it - not as much fun as an old 911, tho nicer for those trips across the US and back.

sigh.... so true.... for me (& my '74) it will be a gradual process - i.e. one bit at at time as funds allow. First up is LSD and a seat / harness. Both will probably be sourced used.

Yeah, the watercooled ones don't appeal to me either....

That's certainly what I do. AWD Subaru for winter / trips, '74 for fun and track. My wife's got a lo-miles Acura RSX for 'round town. Got it all covered... except for that $25k...

i realize im late to the party and the guys after me have hit all the bullets, but what you dont mention is budget.

At the lower end of the scale is just refresh rather than upgrade.

handling - new shifter bushings, turbo tie rods, new sway bar bushings, new motor mounts, high performance tires, sport shocks.

Then you go up in dollar value as you start to upgrade. this may be subtle but tasteful mods.

Wevo coupler, Wevo shifter, wevo motor mounts, Steve Wong chip . Elephant racing bushings, aggressive alignment, SSI exhaust with 2-1 muffler

all this was without cracking the case to do 3.4 conversions, twin plug machining, aggresive cams.... this gets very expensive and stuff usually the track guys are into , but i would invest in driver ed after stage two before any of this.

Hope this helps.

Unless you feel you are lacking power (pedal to the floor all the time) I'd just go with a cat bypass and a throaty exhaust.
Mental horsepower goes a long way!

didn't state a budget, I'll say now it's closer to 15 than it is to 25 this leads me to

Default Cat Removal

My 87 Targa is all stock. Never molested. Has the original exhaust, ect, etc. After talking to several guys in the local PCA over the last 2 years I decided to replace the cat with a Fabspeed pipe.

It was a nightmare getting the 9 bolts off but I did it after much penetrating oil and swearing. I sheared a couple bolts and stripped a wrench but removed the cat without any harm to any of the exhaust components.

1 of the 3 supplied gaskets needed to be slightly modified (Dremel tool) as it just wouldn't line up with the new bolts and a couple of the supplied bolts were of different sizes (are you listening Fabspeed) but the fit of the pipe was precisely correct. I torqued to specs as recommended in the Bentley manual.

The results: On start up and idle there is no perceived difference. Driving is another story...the engine does indeed seem to breath better, it's gained an attractive base note, and on accelerator lift there is a slight burble. There seems to be a smoother delivery of power.

I don't like losing the originality of the car but the added performance may make up for that. Now to consider replacing the muffler.

I am listening, and promptly gave my shipping department an earful. Apologies for the bolt mixup! Glad you are enjoying the upgrade, it is a nice bang for the buck on these cars

^ Is there a Fabspeed thread and/or install/review thread? When I get mine I'd like to post in it.

Thanks for asking! I did find one from awhile back. Can either post in there or start your own

Fabspeed guy!!! Is there any downside to installing a single outlet muffler vs a dual outlet muffler?

Thanks

It sounds like Grrrrr instead of GRRRRR!

But seriously, the dual exit version does have a bit more sound and performance potential than the single outlet. You can also put a cap on the muffler outlet and switch from dual to single in about 10 minutes, so it's nice to have the sound options depending on the occasion.
