3.0 RS inspired 3.2

[911-32]

I thought after many years of following others projects on Pelican I should update my own. My 3.2 has over 10+ years become more and more of a trackday car gaining a wider body, losing an interior, gaining a 6 point cage, losing most metal panels for plastic etc. Suspension, brakes etc, all done, so more recently my attention has turned to the engine and specifically fitting a 964 plastic intake to a 3.2.

Over the years I have asked a fair few questions of various people about how you might do this and whether it would be worth while. I have seen the 964 plastic intake used to great effect on a 3.5 motor completed by Ninemeister and more recently seen Rothsport doing 964 or GT3 intakes on 3.0 race motors.

Having collected the pieces about 3 years ago, its fair to say this idea has been a bit of a slow burner, but I am finally completed and now mapped on the rolling road and as they say the proof of the pudding is in the eating. Just to recap, my engine is a rebuild euro 3.2 running supercup cams and 1 5/8 equal length primaries exhaust. With a slightly less good exhaust (it has proper 3-into-1 merge collectors now) and the vane type AFM, it made around 260fwhp and 217lbft of tq on a number of dyno runs (dyno dynamics). Now with a MAF and the 964 intake, its making 283fwhp and 249lbft on the Ninemeister dyno.

Its an interesting project and I got good counsel from people like Rothsport who assured me it would make good numbers. Its sounds great - more GT3 than 3.2 - and really pulls hard in a LW 3.0RS type package. I have never seen much information on this spec of engine before so I thought I would post it on Pelican to add to the knowledge base.

This is a comparison to a standard 3.2



Here is how the engine looks - confuses most people.



And here is the car, with Magnus approved red/white theme.

It's pretty slick. The power curve is very "oem" in that it isn't overly peaky. Nice, smooth, and progressive like a factory engine. As one would expect considering you haven't gone overboard, using mostly OEM parts. You increased airflow with the intake, cams, and exhaust and raised the redline. Nicely done. I'm sure it's a pleasure to drive.

Great car - great evolution over the years.

Very cool.
What MAF and ECU are you using? And are your still using the stock distributor in a single plug configuration?

[911-32]

Single plug, standard distributor and motronic. The MAF is a Bosch unit and the box that translates the signal for the motronic is a project that a UK guy is making, but not yet for sale. This is box 3, I think.

The whole project is on the impact bumpers forum in excruciating detail

Great, thanks, I will try to find it over there.
