who's the most reasonable for twin plugging
 

I am collecting parts to efi my turbo I have a spare set of heads. I just had them ported and matched for the 3.2 intake. Any way he didn't have a jig for drilling them for twin plugging he mostly does heads for NASCAR. So i need to get them drilled for twin plugs still. Who is the most reasonable for this? I will send them disassembled. So they just have to be drilled and sent back.

Twin Plug
 

Ken, I run the engine dept at JB Racing in Tavares, Fl. we do them all the time. with clean/disassembled heads its 495.00 including the holes in the ex. covers, we can do 12mm or 14mm,
Mike Bruns

ok since i already have a set of 964 covers would it be any less? the stock plugs are 14mm correct?

Stock plugs are 14mm. The serious racers use 12mm instead. I wonder why, is it to preserve more thermal mass in the head and more strength?

Ollie's, in Arizona, $300. See their web site for prices, excellent work.

Ken,

I have used ollies for all of my case mods and they are tops...... Can't go wrong with them.

JB is located in Florida as you are, so shipping is easier/less $$ and they build some serious motors with a great reputation both on track and street.

I have had great service from both.

ok So the heads are already disassembled and i already have a set of 964 lower covers. So looks like it shouldnt be over 300.00 thanks.

Doesn't "cgarr" do them?

Probably hard to beat his price.

Ken, less the holes in the covers will reduce about 25.00, the reason to use 12 mm is to keep the head vol. down for compression, we weld up the bathtub size stock relief and reduce that as well to keep the vol down, the more dome you keep out of the chamber the better they breathe.

Mike Bruns

OK that makes sense but it shouldn't really matter that much in a turbo motor should it? And what plug would be the equivalent of a w3dpo in a 12mm plug?

Did Ollies move from CA to Arizona? I used Ollies for all of my machine work. Very satisfied with everything. I would have to admit that if I were to do it over again I would more than likely use JB Racing though. They have an excellent reputation and are in driving distance from me. All the shipping was a pain. If I had the cash I would put all my parts in the back of my wife's SUV and drive them up to Mike Bruns and have him assemble and tune my Motec ECU . I just want to drive my car again.....

He also builds what I consider to be the best twin plug distributor in the business.

i'm going to going with sequential fire coil on plugs. with a ms-3 ecu

well i am still collecting parts, one of the reasons i decided to go with the MS-3 is there are so many people who know how to tune them. Several here did the tuning on their own.

Another reason to support Mike & Co., as he shares a lot of learned experience here on the forums that you can't find just anywhere.

That said, i'm a supporter of cgarr because he's a good friend in our "local" circle of midwest DIY'ers and racers. If you have something good to barter, Craig probably can't be beat. :D Craig is good people, as is his brother Denny.

+1 for Aaron Burnham.

OK thanks every one!! it'll be acouple months before i can actually get to it.
