3.2 with Motec and Throttle Bodies

[911-32]

I have a chance to buy a MOTEC M8 engine management system together with a set of individual throttle bodies and all associated hardware.

One day, I would love to use these together with high compression pistons, nasty cams, lightweight rods and racing rod bolts, light weight valve train etc, etc, but budget won't permit that right now. Any thoughts on using these on a basically standard euro 3.2?

UK tuners say you can get 265-270hp just using MOTEC to control ignition and fuelling on a std motor, so with throttle bodies...

I hope to have pictures to post later today.

Looking forward to any and all opinions.

I would jump at it.

as a matter of interest, what uk tuners?

[911-32]

9M and Bob Watson both offer Motec packages for around £5,000.

RWHP - In someone's dreams

FWHP - "Specing" above 6000 RPMs

Its FWHP. I don't know if you know the UK Porsche industry, but if you do, you would realise that Bob Watson in particular is pretty well respected (in the same way that Bruce Anderson is in the US) and has a dyno in his shop. His hp claim is likely to be realistic.

Also check out this link to 9M: http://www.9mracing.co.uk/html/modules.php?op=modload&name=Shop&file=index&req=viewproduct&productid=2467&quickview=1

What is "specing"? Its not something I have ever heard of.

Thanks,
Richard

Hi,
What is that in US dollars?

If I wasn't a turbo guy I would do it.

Go for it and have fun.

The 3.2's choke point is the exhaust. With an SSI style exhaust and a motec 265 to 270 seems like fairly reasonable number for rear wheel HP.

Assuming a 15% loss then that is 225 at the rear wheels. Right in the ball park.

Now if you put in good rod bolts, a nice cam, and maybe some head work, then you would have a monster in training!

Richard, here are a couple of ideas:

1. To really take advantage of the individual throttle bodies, you need bigger cams.

2. To use bigger cams, you must change pistons.

3. If you use bigger cams, you will probably rev higher and you may want to replace your rod bolts in a 3.2 with ARP/raceware/etc.

on the other hand, bigger cams and individual throttle bodies are the only way to get a bunch of power out of a naturally aspriated 3.2. other improvements do exist, but at some point you need to go this direction.

The ITB and motec should work fine on a stock 3.2 once tuned, but I don't think the horsepower gains will be too substantial until you make the cam/piston change above.

That would be the whole point of Motec/individual t/b's

Just my opinion m8....£5k is a lot of money to spend for an extra 40hp.
I would sell your car put the money towards a 3.6 or better 911

so we agree? I was just trying to explain why this setup is desirable and what is needed to really take advantage of it.

that will buy a nice turbo setup............

[KobaltBlau]

oh, if you are planning on paying the full 5K pounds I would look at other options first as others said. definitely not worth it on an internally stock 3.2. If you were getting some great deal, maybe put it on and do the internal work later, but if not I wouldn't bother.

Do a search under CamB (fellow New Zealand Pelicaneer) and 3.2.
You will find lots of info (incl dyno sheets) on a twin plugged, high comp, MFI/Motec 3.2 he had built.
Nice motor!

[911-32]

Thanks for all the feedback. Cost in the UK seems to be about £4400 (apprx USD8000). See the 9M link in my post above, for 265hp on std euro exhaust and 270hp on SSIs.

I would be hoping to pick up the kit I am looking at for more like 50% of that cost. If the price isn't right I am not buying. I am somewhat in the dark regarding what this sort of set-up would retail for new - any thoughts? If you can help me out on price information, I am hoping to put a bid in tomorrow.

My plan is that it would initially go on my std engine and later (funds permitting) be rebuilt with pistons, cams, rod bolts, valvetrain and exhaust. I would expect that bolt on to a std euro engine, ITBs and Motec would be 265-270hp minimum and with all the goodies 300+hp must be on the cards. I think your opinions are much the same.

Again, thanks for the feedback.

Yes, I know Jon Waring who built that motor. I used to live in Auckland and Jon and Peter Booth looked after my car at that time. I have sent Pete an email and await his feedback as well.

Cheers,

I don't know what parts the kit includes but $8000 seems about right for everything that you would need to get your car running.
I just put a DTA EFI system on my car. It cost me about $5k for everything. I think if I went with Motec it would have been $2k more. I didn't use indiv. TB's, I used Carrera manifold. So the TB's weren't factored into the price. If you can get a 50% discount you are my hero.

Its third hand not new. It was on a turbo car (not known to me) and then a 3.4 race car. The asking price is probably no more than 50% of retail. I hope to cut a better deal
