3.2 conversion progress

H2odiesel · 01:58 AM

For version one of my likely never ending project, I decided to go with a MSD with retard on boost for the timing duties and a BEGI for fuel enrichment. No charge cooling on this iteration and a home made zork for exhaust. I still have to mount the AFM and Boost gauges, but I hope to do a little test drive in the next day or two.

Did you forget the "turbo" in the title? I thought you were swapping a 3.2 into an older car by the title.

Very nice by the way. Triple-K turbo? I see a 4-bolt turbine flange.

How much boost? Long term goals?

Pretty clean so far. It really would like some kind I cooling in the future. Did you use Porsche wastgate? What turbo and diverter/blow off used? In sure your msd details are enough for you but we'd like more details.

Nice zork

Fixed the title Tippy, thanks Nkowi. I am using a 930 J pipe and a KKK 3LDZ. On the waste gate I decided to bite the bullet and go with a new Teal F46. The blow off valve is an Ebay billet copy of a teal. As for the ignition and timing duties, I eventually want to move to Mega squirt, but for now I'm using an MSD 6BTM. It is an all in one ignition and retard on boost unit. The rate of retard is adjustable from the drivers seat from One degree per pound of boost to 4. For instrumentation Ive gone with AEM, so far their AFM and boost gauge. It looks like I'll be adding a fuel pressure gauge in the near future. I am running .5 bar boost and will stay there in the hope my 915 trans and clutch will hold up for a while. There is an intercooler in my future. I am trying to decide if I want to play with the spool gun I have access to and welding up an air to air unit or be completely different and do and air to water, with radiator and fan in the rear wheel well. I've gone over my costs to make sure I'm not forgetting anything, but it looks like I am under $2500.00 so far.

Thats close to my set-up. I also run BEGI and MSD6BTM, works great! You could also ditch the stock barn door afm (which wont last long under boost) and go suck thru using a split second controller and a Ford MAF. You keep the stock chip as well. It provides much more adjustability and give you a little room to grow.

Everybody says the barn door won't survive boost. Mine lasted many years no problem up to 1.2-bar.

Come on Tippy, I know you really want a MAF.

Speed density for me!

Sure it is. After clicking on "edit" go to the advanced function. You'll figure it out from there.

I've got a few hundred miles on on this project and after a few early teething pains, oil leaks and silicone coupler blow offs, my impression of the results is WOW! The boost comes on at about 3200 rpms and by 3600 the waste gate is opening and holding boost between 7 and 8 psi. The acceleration from 3600 to 7000 in second and third gear is so rapid i cant effectively look at the tach, boost, O2 and back to the tach again before it is time to shift. It winds 4th gear out like it did 3rd normally aspirated. I love the rumble and moan of the zork right now and if I don't get many complaints I think I'll keep running it this way. So far only smiles and thumbs up from other drivers and pedestrians. My one real problem I have now encountered is the slippery slope of wanting more. I can't seem to get my mind off of the thought.

Cool, same sort of results I got and similar'ish setup, but mines on a 3.0SC engine and 0.5bar boost.
My 915 is still going but not sure for how long, I could swear it now feels a bit rougher after 1000miles of boost.
Gues thats another project soon

That boost pipe is powerful addiction. Megasquirt and an intercooler are just around the corner by the sounds of it.

H2odiesel · 02-07-2014, 04:08 PM

The limitations of the 915 transmission have me concerned that any more effort at increasing the power will be assuring trouble. Part of me wants to look at fitting a G50 or a 930 box next. The other side is considering returning this car to stock and selling it. Then looking for a 964 that needs some engine work. I'd enjoy building up my own engine but I do have a budget.

EXACTLY
You are now insane!
but in a good way

I was a defender of unmodded cars and turned my nose up at you revheads for drifting away from the factory design..

But if it makes it go faster and harder by the ingenuity of the owner im sure it makes Mr Ferry's smile

You can inject some water/meth in there and forgo the intercooler! Nice work,cheers, Stef.

Tippy · 02-08-2014, 04:10 PM

Just love the simplicity. Such a clean install. Some Marmon flanges and it'd look OEM.

As others have said, meth would give you more power and safety.

H2odiesel · 02-09-2014, 05:13 AM

Thanks guys, I appreciate the kind words and encouragement!

I love my car, but I'm scared about too many things with it. I too still use the 915 for $ reasons and because I'm still driving with it, here's my thoughts.
My car right now scares me because it's faster than I am. I run a .8bar spring but with my new turbo I'm getting boost creep in 2nd through 5th gears to 1bar +. I love the power don't get me wrong, but the gearing is so close that it's literally scaring me as I drive it at 100%. My wife says "well can't you just control yourself"? I'd like to say yes but I can't. I think I'm too addicted to the boost....seriously.
I've already gone through one 915 gearbox. I'm trying to be easier on this one but it's only a matter of time before it too is shredded. I told my wife I may sell it as soon as I get the interior refinished and she just looked at me like I was an idiot.
I guess what I'm saying is this, get a 930 gearbox because it has taller gears, or a g50 for strength and less worry about the 915 grenade behind you.
I'm seriously looking into getting a 930 box over a g50 because it's strong And it has taller gears so I don't feel like I'm going to kill myself. It's either that or I'm selling this beast.
Is that too dramatic? Sorry.

H2odiesel · 02-09-2014, 06:12 PM

Not too Dramatic at all brother. I love my car and am thrilled with the added performance from the turbo. I feel a bit guilty after a hard romp through the gears a few times on the way home like I'm slowly sucking the life out of this beauty. I either have to upgrade the transmission and go through the engine or return her to stock and find a more gentle owner for her. I know I'd be lucky to get a fraction of the money back for any work or upgrades I do and might well end up with less value when it is time to sell.
