Porsche 911 - 3.2L PMO ITB

[kdguy01]

The problem is not the engine.... it's getting the right fuel/air/advance settings for an ITB equipped engine. It's pretty difficult to place an Idle-Air-Control-Valve with ITB's. Sadly, I don't know anyone in Europe who's done this. Try the Pelican Parts website?

[kirillnilut]

Will it be the same with a 993 engine?

Maybe by chance you know someone doing these conversions in LHD europe, where I actually live (and often freeze below -20)

[kdguy01]

Still hard to start when it's below freezing. But once fired up, she runs like a kitten!

[kirillnilut]

Amazing car!

How is she now?

When cold?

[kdguy01]

Cold starts can be pretty rough. I backdated my heater controls and installed a hand-throttle lever. Now I can set the idle higher until things warm up. It takes much more priming to get it to start when the temperature drops below 50degF.

[NicoB998]

Thanks for answering my previous question. I was also wondering how you got such smooth start-up... I am told that cold starts with ITBs require keeping the throttle slightly open for 30ish seconds. Is it the case with your car as well?

[kdguy01]

I experienced no low speed drivability or loss of low-end torque. And any noise can be easily quelled by your choice of air filter. I now run a modified 1971 Air-box. Nice and quiet.

Mind you, I’m now running M&K sport mufflers. Now that’s loud!

Contact Richard Clewett (Clewett Engineering).. He’ll steer you right.

Hi there - I hope you still read this. I am considering installing ITBs on my 1996 varioram engine. My main concerns relate to low end torque and noise when cruising around town or on the highway. Could you please comment on these two issues?

I am well aware that low end torque will be somewhat compromised, but how is drivability (say in a parking lot)?

Thanks

"i think you dont know what to do with your life."

"I think you should go get a real job"

haha, lol

nice setup though

[ROCKSOLID19]

@kellzsanator When I heard that I thought WTF???

[oinkyerdoinkyerzwazz]

Purrs ,she so smoooooth!!! I want that motor!!!!! Oh gaaaaawd !!!!

[heyyitsandy]

a 3.2 carrera on ITB's - that sound is addicting.....doesn't look bad either!

[keomo]

Amazing! I'm really looking into converting to PMO EFI when I rebuild my 3.2. Great sounding engine and seems like really quick throttle response.

Any additional videos you could share, please?

[bjhintgen]

Beautiful

[alberello1]

absolutely stunning, it seems a new car!!

[AM007009]

that engine is a thing of beauty!

[byf43]

Acoustic art for the purists. Even though I sold my Carrera 3,2 I'm still addicted.

[MikeRyanPerformance]

Love the set up, I'm either gonna do itb's or boost not sure yet. Do you know what power your making now...check out my dyno video!

[kdguy01]

Not sure what HP she's making, haven't been to the dyno yet.. perhaps in the spring. I do know that she's faster than before with much better throttle response.

[911myporsche]

Really nice work. ITB's are a great tuning addition to the 911 engine. What size did you go for?

[kdguy01]

46MM ITB's with 26#/hr injectors. Seems to work out fine with good throttle response and wide power band.

[twistoffat]

Simply stunning work. Well done

[beforever]

I have always wanted a pre 89 911, I thought they were carbed, if so where did you get the ei conversion kit from?

if I'm wrong I am so ashamed.

[kdguy01]

The early 911's were carbed. Later they went to mechanical fuel injection, to be following by the Motronic fuel injection in 1984.

[klutch323]

absolutly stunning, makes me miss our 1970 targa t

[PA28140]

My God that sound good!

[antaresplus]

Have you Dyno'd this setup yet? Be curious to know what real rear wheel horsepower this setup is reaching?

Where did you get the fuel rails or did you make them yourself out of billet aluminum or did you just TIG aluminum pipe halves to base aluminum channel stock?

[kdguy01]

Haven't dyno'd yet.. still tuning. Perhaps in a month or two. Fuel rails are made by PMO.

[PeterLorre]

incredible work!!!!

[BobKontak]

Stunning engine compartment as well!!!!

[kdguy01]

Thanks Bob. I just returned from another tuning run. She's getting better all the time. Still a litttle flat above 5000RPM, but with a few more tuning runs, I'm sure I'll have the fuel curve fully sorted.

[BobKontak]

Awesome. My 81 stock SC runs great but this demonstrates the beauty of the electromotive ignition and the quick throttle response of the PMOs.  Suh-wheeeeet!

[Ralphthrash]

What is the ignition replacement system you have?

[kdguy01]

Electromotive coil-pack, plus TECgt ECU

[rollandburn]

ya man that just rocks!

[mmn710]

I'm really looking into doing this to my Carrera 3.2. How much did the whole set up cost you and was it worth the work?

check out some of my vids too. You can get an idea on how our car sounds with straight pipe haha.

[kdguy01]

Budget around $7K for the ITB's, ECU and miscellaneous bits and pieces. Was it worth it? Well, I'm pretty happy the way things turned out, but there's cheaper ways of making power.

[PA28140]

Damn that sounds goooooooood!!!!!!!!!!!!

[kdguy01]

Thx, it's getting better as I refine the tuning.
