That pump certainly looks right; on the outlet side, you have the banjo fitting going on the end of the check valve that comes with and screws into the pump... so it sounds like maybe you are missing ...

Yeah, probably a good candidate for a 1.8T swap or such - get the performance to match the looks!

That's a strange one.

We too have struggles every time we bleed the RF on our '79 - but it's been converted to 5-lug and so has a bit different line routing... and the problem is different, not blo ...

Hey, I recognize that car! Was seeing the ads floating around in the feeds...

Yeah, can ditch that vac regulator, and yes you can plug the vacuum ports to the engine, we run with none on our raceca ...

I am a bit confused about the statement:

Turns out mine has current when ignition's off, but when ignition on, it no longer has current.
Furthermore, instead of having 6V on 15 with ignition on, t ...

Welcome!

Where exactly are you in SW MI?

Re: vacuum booster - I assume you mean the little goofy thing on the fender with 4 small vacuum lines going to it, not the brake booster? Yeah, I should ...

Those rubber bumper mounts, aka vibration isolators, with studs at each end, are pretty generic metric auto parts; there should be good sources over there for such.

Here in the states I'd get 'em f ...

I'm surprised that your motor will knock that easily. Doesn't seem right, perhaps it wants some clean-up in the combustion chambers?

We also have an NA racecar, with a basically stock NA head on it ...

Thanks for the data.

Couple questions:

1. You have all your timing in at 2500 RPM from 85 KPa upwards. I was going with the stock Porsche ignition curve being all-in at 3000-4000rpm, are they to ...

I repaired mine a couple of times; well, one steel repair, and then a re-seal from improperly sealing it the first time.

I used POR15 brand seam sealer, with POR15 coating over the top of both the ...

Update - posted my latest maps, so linking from the Rennlist thread... tuned for US 93 octane gas (though far from the limit, I have a WBO2 sensor but no knock sensor and haven't run on a dyno, just s ...
