Roxanne - budget milano/75 track car

[nizam]

Now, it's not all doom and gloom. You could easily take the pulley on the left to a machinist and have him turn down the timing wheel by 2mm or so, and you'll have plenty of clearance.

Alternately, you could run the 164S crank pulley AFTER rebalancing it to match the Milano 3.0V6's crank pulley. The counterweights between the 164S and the Verdes are different. If you put on a Verde flywheel, make sure your pulley is counterbalanced to match.

This means you'll run the 164S serpentine-driven waterpump, and you'll have to get a 7-groove serpentine pulley to put onto your 'cute' alternator.

OK, have you thought about how you're going to run your injectors? You'll need the 164S injectors to be driven by the Motronic ECU. I'm not 100% sure, but I don't think they'll go onto the Milano's fuel rail ... that is unless you are going to use the 164S' fuel rail as well as the shiny runners

I presume you'll be able to get the 164S plenum cut up and rewelded just like the one on your 75 GTA's right?

Is there any chance that the straight pipe caused some extra back-pressure on the engine, contributing to it blowing its seals?

Nizam,

I have spoken with Andrew (Garcia Alfa Racing) and APE (Larry Jr, I think it was, as I may need some pieces from him for the puzzle), and I think everything is somewhat under control (at least I have good idea and a clear picture of the way forward - keeping things simple). I will run the 164S engine pretty much as is - less AC, PS, 164 alternator. No putting Milano stuff, in terms of belt drive, pulleys, crank pulleys, waterpump, on the engine. It will run Motronic, 164S injectors, 164S crank pulley, 164S water pump. I will put a serpentine pulley on the alternator and line it up with the 164S waterpump if I can (need custom bracket for it anyway). I plan to use the 164 intake plenum as well.

One problem Jes, the Motronic distributor might not clear the Milano's firewall. When you mount the engine for rear wheel drive applications, the dist is now next to the brake booster/fire wall. I have not followed this thread completely but, why not use the complete 164 belt system. Make a bracket to move the alt to the position of the ac compressor and use the 164 PS pump. You would then only need to make custom hoses. My philosophy is try the simplest approach first.

Jes,

So are you gonna use the 164 plenum with the U bend or your GTA style mod to the plenum?

Maybe you can sell me the 164 PS pump?

[AR4me]

Andrew,

Read above - I just outlined my approach. Very much like you just suggested. Though, I run without PS, making things even simpler

I would like to keep a stock airbox, either milano or 164. Roxanne is still registered and fully street legal (from a smog perspective). I hope to keep it registered, and hence it will retain the cat.

I got lots of space in the engine bay, so I may have an easier time than you fitting the airbox.

On a different topic: I'm in the middle of figuring out which fuel cell, ATL or Fuel Safe, and which size to get - that stuff is pricy, but then again, expenses on safety items should not be spared! I will get a decent sized cell (probably 15G) since enduro is on the horizon for Roxanne. I have the Milano fuel tank and all associated stuff out of the car. Anyone interested in a solid rust-free Milano fuel tank?

So, some investigation (according to Larry Jr's instructions) of my 2.5 engine still in the car indicates it is a later model Milano 2.5, and hence, my bellhousing and flywheel may bolt up just like the 3.0 components, from a fitment point of view.

Furthermore, Steve (Alfisto Steve) looked up (based on VIN of the 1992 S) that the crank of my 164S engine has the finer thread (1.25 pitch). So, I will order flywheel bolts from APE, but should otherwise be good to go

This was hinted at, but for reference for the next guy reading this.
The Milano injectors are Lo-Z and the 164 injectores are Hi-Z
So the ECU needs to match the type of injector used. if you try to use a Lo-Z injector on a Hi-Z ECU it will smoke the ECU.

[kredden]

Unless you go Megasquirt which has support for both :-).

Which type is more common/more widely available?

[AR4me]

So, I ordered the 1.25 pitch flywheel bolts from Larry Jr. that I need to mount the Milano flywheel onto the (late model) 164S crank - only $40 - these are not commonly available! The 164S bolts are too short, and the Milano bolts too coarse a thread for the late model 164 crank. According to Larry Jr., balance wise, I will be ok with the 98 grams counter weight of the 2.5 Milano flywheel. He mentioned that the 3.0 164S flywheel is also 98 grams counter weight, and so is the 164S crank pulley. He even ran his own race car this particular way for years without any issues. So, it looks like my plan is in in good shape and has been proven in race application

Injectors will not be an issue - that's basic stuff. Like I said, it will be all 164S engine: Motronic, 164S crank pulley, 164S waterpump, 164S injectors, harness, intake plenum, AFM, harness... Only Milano parts will be oil pump, drive, pick-up, alternator, sump, bellhousing, starter, flywheel.

Oh, and my donor 1992 164S should arrive early next week
