24V conversion

[larry]

Here is my latest 24V conversion for a customer going into a GTV-6. This one has a single serpentine belt, power steering, Alt. and A/C and fits in 116-119 cars. Single belt drive took alot of fabrication and trials to fit the car. I never used Power steering in either of my own cars. We just purchased a wrecked 95 LS.

Very nice job.

I'd love to have one of these in my Milano!!!

John, junglejustice I tried calling you back. They are 24V pulleys on modified PS pump and bracket and 91-93 164 alt and the A/C is late milano pump(small I.D. bearing) on modified bracket with 91-93 164 A/C clutch drive that's modified. LS compressor to long fittings run into my design headers. This was the easiest way to fit it all in a milano without cutting the car.

Larry,

Does the 164 pump have the correct pressure to work the Milano rack?

[inhistoryclass]

can i ask what you did about the computer/injectors? I am trying to put a 164 base engine into a milano 2.5 and i was told i need to switch the wiring harnesses? Keep in mind that im trying to use the 164 plenum. Could you give me any information on this.

The 164 and the Milano came with different wiring harnesses, for different types of fuel injection systems.

In a nutshell, the Milano came with an older version, while the 164 came with a newer version. They are not compatible. You could make the 164 engine work just fine with your stock standard (old version) system in your Milano as long as you reuse all the Milano sensors, plenum, etc. Many a transformation has run this way and they work just fine.

If you want to run the 164 intake runners and plenum, things get slightly harder. First and foremost, the injector rails will also need to be switched to the 164 rails. Unfortunately, the 164 rails come with 164 injectors, which won't work with the Milano's older EFI system. Let's say you managed to swap out the Milano injectors onto the 164 injector rails, you now need to find a different fuel pressure regulator because the 164 runs a higher pressure injector rail versus the Milano's injector rail.

The above is just the tip of the iceberg. I'm not discouraging you from doing the conversion, but you have to go into this project with all four eyes open (including the two in the back of your head). Else, you will pour a lot of money and time and have boxfulls of parts and a half-disassembled Milano in the driveway.

Finally, many conversion questions have been answered, or at least debated, here:

164 engine into a Milano thoughts/knowledge?

(might have to follow some links, hey, no one said it was going to be easy )

Larry, that's a nice pulley system. I like the one you did for my racecar too. Same as above, but without the A/C compressor.

Thanks for posting that picture and description Larry!

Guys, as a side-note - please try to buy what you can from Larry, rather than draw information and try to save a couple of bucks by going somewhere else for minimal savings! For BIG savings - by all means - we all compete and you SHOULD shop it! At the same time, guys like Larry and Dawie de Villiers and Barry TRULY are PIONEERS and they are ALWAYS very forthcoming with ideas and solutions, (only to have folks go off and buy somewhere else, just to save very few dollars - relatively speaking!)

Having said that - Larry, you know that my stuff usually comes converted already from Glenwood in South Africa however, I am in a pinch on an after-thought on one conversion and now I need your help please! I need a complete setup for one conversion to run A/C, P/S and alternator.

What I do have are the Milano, P/S pump, A/C pump, alternator and standard bracketry, however, it seems from our conversation that I will be dumping most of it! Assuming that I DON'T have any of the 164 12 valve/24 valve parts, what all can you supply me with today and what do I need to go and source?

Give me a buzz please - Thanks again!

Nizam is correct, the 164 uses different ohm injectors, not copatable with L-jet. You should use the Motronic system, simpler yet better. Motronic is more adaptable to future mods such as cams and such. L-jet is very limited. To do the motornic conversion you will need all the parts from a 164 AFM, harness ECU, injectors,crank angle trigger, and crank pulley, etc. To fit in a 116 chassis you can move the dist. to the front right location, some mods to your old dist needed(must be turned into a fixed shaft, no mech adv.). If you want to do this you should call me to get all the info on the mods to be done.

John, I was at the shop Sat and here's what I have.
24v double idler bracket and pulleys, 24v P/S pulley, 12v P/S pumps, 12v 164 A/C pulley/ clutch drive, 24v Alt mount, I am out of 24v alt pulleys.
I will be at the shop Thurs call me. 209 833-8330

There is a brass restrictor inside the 164 pumps that dictates the low rpm pressure, bigger hole less pressure at 1000 rpms but will build to higher rpm until bypass opens. small hole and max pressure could be reached at 1000 rpm's and bypass opens and that pressure stay all the way up to redline. The bypass opening pressure can be changed, by spring replacement. I cannot say how it will work in stock form, I have never put P/S on my cars, but it can be tailored to work how you would like it (low boost or more) rather easily

Just checked both cars; here is what the pumps will put out:

Milano, ZF, 1.35bar
164, ZF, 1.00bar

I doubt either will use max output except perhaps during parking maneuvers. I just got a rebuilt Milano rack that I'll use with the 164 pump. We'll see how well that works (or not).

Thanks Larry,

Can you buzz me so that we can ge a deal struck on this stuff - also, let me know what else I am-a-huntin' fo...!?
