3.6L transplant guide

[cliyde]

+1 on Steve T. Very knowledgeable and helpful with my 3.6 transplant. He makes/fabricates lots of conversion gear. He should be able to get you going and keep you on the road once there!

Cheers!

I'm much more concerned about overheating at idle in traffic than I am with overheating at wide open throttle, but my car never sees a track anymore.

My car has a 915 and a '95 3.6 and they knocked a bit of extra space in the interior to make room above it. I'm not sure how the G50 and varioram plumbing will affect that, but another thing to be aware of.

I ran the stock passenger side Carrera oil cooler with fan for a while and it was fine 95% of the time on the street. Oil temps would creep up in heavy traffic when it was 85+ degrees outside.

The varioram intake fits in my '87, but it's toight like a toiger. Swapping out the throttle cable required a friend with pipe cleaner type arms.

+1 on Steve T as well. I bought the kit from him and then subbed in a couple of things I wanted done differently. He was also super helpful troubleshooting some issues I was having with wiring. I shipped him my ECU and he even tested it in one of his cars to confirm that my ECU was good. Great post-sales support.

Patrick Motorsports has an amazing array of parts on their website but they are seriously expensive. I do buy parts from them but it is always my last resort.

OTOH Steve at Instant G is very helpful and his prices seem fair to me.

Pricing is kinda hard to sort out, but:

3.6 Engine Conversions – Instant-G

Are they still selling 3.6s that they've gone through for $15k? That seems...unsustainable.

The '87 G50 flywheel will not work (sensor teeth are for a 3.2 motronic not a 3.6)
However, an '89 964C4 3.6 used a standard, non dual mass flywheel.

On my '89 964 3.6 transplant to an '80SC, I used it's 240mm flywheel with the 915 by machining it to accept a 915 225mm pressure plate. Has worked great since I did the swap in 1992. It was my only path as there were no "conversion" flywheels or other parts back then!

Just call him.

2 years ago price was $12.5K.

An iconic air cooled Metzger motor that is bulletproof, glad I got one

It's good to see all this satisfaction with Timmins. I've already noted that I'm a happy customer from way back (I think I was the first to use his kit for a swap on the west coast).

One thing Patrick did solve is the issue of oil pressure readings doubled when the 964/993 pressure sender is paired with the earlier gauges. The older senders have 10-184 ohms of resistance cover a range of 0-150 psi, while the newer senders spread the same 10-184 ohms over 0-75 psi. Patrick found an adapter that will let you screw an older 0-150 psi sender (M10) into the newer engines' M18 hole.

I mention it because there are a cluster of 3.6 swappers here.

VDO probably makes a 10-184 ohm gauge over 0-150 psi with an M18 fitting -- maybe one of you found it?

Perhaps I am incorrect, was it not Hans Mezger? I think Metzger means "butcher". I only know this because I looked it up.

question
I have the 1986 3.2 with new B&B SSI
Can I use my SSI B&B header on 3.6L conversion?
My SSI is a thin Flange header

You can.

You will need to change the mounting stud position on one side, RH IIRC - which probably means it's the LH

Anyway, the 3.6 has 4 threaded holes per port for 2 studs.

Depends on if its a 964 or 993, only 993 flanges are different.

Depends on what the primary pipe sizes are. You will want at least 1 5/8" OD and preferably 1 3/4" for a 3.6. 1 1/2" will strangle the motor.

964 heads have a stud arrangement identical to earlier heads, you can use either thin or thick flange it's just a matter of either changing the studs or having extra length.

Here's a 3.2 exhaust port


964 studs arrangement is the same as 3.2



993 has both the early and late pattern just place the studs according to need



either a 964 or 993 can use the bigger B&B headers seen here w/ 964 heat pipe

[frankoporsche]

Hello Bill
yes my header at least 1.5/8 OD but on instruction paper said 1 3/4 OD with 3 inch. OD exhaust
Thanks you

Thanks you

B&B come in either 1 5/8 or 1 3/4, so it appears that you have the bigger size, that's good.

The biggest issue will be the oil line, the B&B will want as much vertical clearance as can be provided, a feed line that bends up is very desireable




Even then the rubber S hose is close to the header so some insulation is also desirable

question
looking to buy 3.6L for my 1986 Carrera...do I need to make sure what year or model 3.6L for my car?
Or get the complete conversion and the motor as one package deal from instant-G

Meanwhile:
The external -044 Bosch fuel pump works well.
I did an end to end replacement of the fuel lines with new metric stainless through the tunnel.
The stock 964 fuel filter works well
Route your oil tank breather hose into a puke tank up in the left rear wheel well to avoid oil tank fume deposits on engine
