Parts to converting a 3.0 into a 3.2

[Nitrometano]

Hi, what parts I need to make a 3.2 liter engine from a 3.0 engine.

I know that I need pistons, but the 3.2 cylinders dont use head gasket and the 3.0 use it. I need to change the heads?

Also, I need to change the stock camshafts to 964 cams?

What about the CIS fuel system. I need to replace injectors, fuel distributor, a bigger throttle body?

I can use 46mm carburetorss?

I need to replace the ignition distributor or recurve it?

I need to change spark plugs and install the 3.2 spark plugs.

What power I can win doing the conversion?

Sorry, cant help, but I would like know to where can I buy/order 3.0L -> 3.2L piston and cylinder kits ?? Or where can buy/order 3.2L cylinders if I buy JE piston set ??

I am nowhere near an expert but I have been thinking of doing the same with my dads motor. You can run carbs on it, as far as I know I am pretty sure you can keep your heads, pick your cams and as far as the dizzy I am in the dark on that.


MAHLE builds the "Max Moritz" P&C set which is the 3.0 to 3.2 setup. I think our host sells them.

If you do a search on this topic there is a lot of information, I have attached two links below. I am building a 3.2 out of 79 3.0 ltr SC motor, with 46 carbs, S cams, crank fire ignition and 98mm Max Moritz barrels and pistons. If you wanted these Max Moritz set up I may consider selling them as they are not really the best set up to use with the high lift S cams.

Help me plan my 3.2SS

Where ?? I havent found

[Porschekid962]

Neither have I. I guess Andial is selling them now because they have an advert in the latest excellence showing em and the CR's they sell them in. Andial=pricey.

Anyone know any other places to get the 3.2 P&C's?

Hi Alan. I am very interested in about them. I will send you mail soon.

Andial and SSF Auto Parts are the two exclusive distributors for Mahle Porsche sets in North America. Andial has a few different sets available that are custom made to their specs (like in their new ad) so they would be exclusive. I would budget $2,500-$4,000 for Mahle's depending on the application you need.

You can buy Mahle sport P's and C's from a variety of shops around the country, but they will all come from Andial or SSF. BTW, SSF does not sell retail. If Pelican deals with Andial or SSF, they should be able to get the application you want if either firm has them in stock.

To make it real easy for him, here are the part numbers that Andial and SSF use for the Mahle sets:

98mm w/ 22mm pin - 3.0L to 3.2L

CIS type (9.8:1 CR) - AND 103 983 98 (Andial) or PS 98-005 (SSF)

CARB/MFI type (10.2:1 CR)- AND 103 984 98 (Andial) or PS 98-003 (SSF)

Good Luck!

Slightly OT, but is the only difference between the 3.4 and the 3.2 from a 3.0 the use of the 3.2 74mm crank?

I checked Andial's page for the P&C set but they dont list prices, maybe it scares ppl off haha.

I don't think it is O/T, but yes the only differences to make 3.4L out of 3.0L are the longer stroke Carrera crank and connecting rods. If you are using the Carrera crank and rods, you will have to make sure you get the 98mm pistons with 23mm pins rather then the 3.0>3.2 set that uses the 22mm pins with stock SC rods. Or, use the 98mm pistons with the 22mm pin and use an aftermarket connecting rod such as Carrillo or Pauter. Confused? I almost am writing this.

Mahle uses the exact same 98mm cylinder whether the piston inside has 22mm pin or 23mm pin diameter and that includes the turbo applications as well. You can go all the way to 3.7L with the 3.0L case, it all depends on how much money you want to spend.

What's the old saying? If you have to ask how much, you can't afford it. Don't laugh, I bet people fall over backwards when they hear how much these sets can cost. Maybe they don't want people calling them up and saying there must be a mistake on the pricing? There really can't be that many digits to the left of the decimal point, right?

Keep us updated with how this works out. I want to do this as well.

[Porschekid962]

Carrera 3.5 no im not confused haha. Just trying to put a list together for my dad of the options he has for his engine. He might get a bone stock 3.2 and use that while we rebuild his 3.0. He is planning on using either Pauter or Carrillo rods no matter what engine size. So if the crank is the only other step then it turns into a why not kinda thing. Cant wait to get it started and post pretty pics of the nice shiny parts.

Good luck with your engines everyone!!!

Be silly to build any big bore on a 3.0 cis engine if you have a 3.2.

Over all costs would be much less building a 3.4 or 3.5 from a 3.2 motronic and you'll have a much more powerful and tuneable engine when you are done with the base 3.2. It will even pass California smog which a 3.0 CIS never will.

I agree with rdane. With the 3.2L as the base, you already have the crank and rods and just need to buy the P's and C's to make 3.4L. Keep driving the 3.0L and build a nice motor with the 3.2L.

[Porschekid962]

If the right 3.2 comes around that will prolly be the way we go and then I get the 3.0 for my car, whenever I buy it!
The ideas for the engine are as follows:
3.4 from a 3.2 or 3.0
Pauter or Carrillo rods
98mm p&c's
Elgin cams
Supertec head studs
Steve Weiner ITB's with DTA ecu
Twin plugged heads, port matched to intake and exhaust
SSI's
Possible use of Ti valves, springs and retainers.

Then I get to rebuild the 915 tranny!
It all goes into dads 74 911s IROC look car.

You've got a nice selection of parts picked out, I too like Steve's ITB set-up but until he gets CARB exemption...

For a street car under 7,000 rpm, I think Ti valves and retainers are something you can pass on. Stick with sport springs and steel retainers and spend the money somewhere else.

Keep playing the lottery, if you ever win you can purchase the real-deal slide valve assembly from the RSR. Now that would be cool!

[Porschekid962]

Oh I agree, we originally looked at Henry's slick MFI setups but the adjustability of EFI is so nice and Steve's ITB setup does look just a bit like MFI stacks hmmmm.
Good suggestion on the valves, springs and retainers.

Carb exemption? The car is a 74 so it's exempt already, or were you talking about yours? Anywhat, now im looking around socal for some top notch Porsche only machine shops to start writing up a price list for the rebuild.

[Brother]

Does Clewett sell MFI setups? I'm trying to decide what will replace my CIS as well.

I looked at their EFI stuff. It looks like a set costs around 5000 for everything. What is the price of the MFI stuff? Who else might have it?
