Quick FAQ 3.0/3.2 upgrades to 3.2/3.4

[Trackrash]

The turbo option is definitely worth looking at. It would be interesting to do a cost assessment for the turbo conversion. I would like to see that, if one exists.

I could see twin turbos hanging out the back of my car. The reality is I can't use all the power I have now on the street, but turbos do have a definite appeal.

A 3,6 is the way to go, but the ship has kind of sailed on that one. No question those 3.6s are spectacular performers. However for the money, from what I am seeing now, you could build up an SC motor that could be comparable (I am thinking anyway).

Of course selling the motor you have will offset the cost of a 3,6 to some extent.

Yea, I think a turbo i'd be into the hardware and ECU for $6-8K making about 300RWHP A rebuild to low comp $12-15K

selling my SC engine, $8-9K Maaaaaybe more toward an 18K 3.6L Not sure total cost for ECU and install bits on a 3.6 swap. IF the 3.6 needs a rebuild another $15-18K

rebuild the 3.0L $15K for maybe 250CHP.

for the money the turbo is the best HP per $ by far, but would eat my 915 in a year or two. But in the end you be the most fun of the options.

I see no point in two turbos, modern turbo spool so low that one good turbo makes great power.

Here you go..... 930 Turbo system sold as package or in pieces.

[Geronimo]

Yea, I saw that... pretty complete kit.

I completely agree. The cost for a donor 3.6 is pretty steep these days and the conversion is +10k depending on the car. So typically, you end up Selling your 3.0 and paying 15-20k for a 3.6 swap. You could build a nice twin plugged beast for that.

However, if you're going +300isch streetable hp, then I would take 3.6.

I've been thinking of adding a turbo to my 3.6....
I'm wondering how much boost you can add to a stock 3.6 intake, plastic and rubber boots everywhere!

I am trying to figure out what path makes the most senes for my future engine build... 3.0 low comp and a turbo,

3.2ss

or check out the 3.0L and sell it for a 3.6 swap.

If you have access to E85 a turbo kit and EFI would be a sweet upgrade for power.

93oct would be fine in street trim, I worry that my love of power and boost would have me turning the booth up and eating my 915.

For those of you with 3.2ss what heads did you use? Wayne mentions either 3.0 or 3.2. My assumption is that is 3.0L heads are used they must be early 3.0 with large valves. Currently my 3.0 (83) has smaller valves.

Thanks

Valve sizes are all the same. The later SC ports are smaller, but easily enlarged. 3,2 heads have even larger ports, but they have different studs and the head volume is slightly larger, I have read.

[Harpo]

I thought the studs were changed with the 3.6L
