My new project "Ghost"!, 6Bolted2G! Options

[BudmannG]

Here we are in a new year 2006 to be exact. A new year calls for change and so I have. I have changed from the 1G DSM. A fine car that it was in it's six years of Graves service. I chose to trade the ole'girl for a 2G.
Now this 2G is a great car. It has sleek body lines and more options. I can see everything that I have ever wanted in a DSM when I look at this 2G. I have only dreamed of owning one of these. Now the day has come that I do.
I have done some hard soul searching trying to decide what to do with the motor. I have priced many different rebuild kits, rebuilt motors, short blocks, long blocks, you get the idea. And none could stay within my budget.
As most of you know I started a project called "Fireball"! Well guess where the donor heart is going to come from. I saved myself alot of money making this decision.

Here is a list of the thing that I am purchasing for this new project of mine. I am probably forgetting something.

• 3" exhaust from belittle
• 255 walbro lph fuel pump
• 450cc injectors poopshit!
• DSM Link
• Eprom ECU
• 2G MAFS
• Fidanza flywheel
• Sony Vaio for DSM Link
• Hallman mbc Thanks to akamiami!
• Tubular exhaust manifold Thanks to asiankid!
• Tubular O2 housing
• Lunar boost gauge
• Lunar A/F gauge
• 1G bov
• 14b poopshit!

Like I said before I did alot of soul searching on this setup and it was and is in my budget. So now all that is left is getting it put together. That should start some time in the next week. I have the engine here and ready to pull. I just have to wait for the check to come in, LOL. Taxes, anticipation is KILLING me.

I am open to comments on what I have decided to do. I have strong shoulders, give it to me. I honestly think I have a reasonable setup for what I was looking for in the beginning.

Thanks for taking the time to read this long boring thread!

[AWD DSM 1]

You'll want to add a AFPR to that list.

Also, skip the a/f gauge and go for an EGT, you'll get more usefull info out of that. Most people agree that the a/f is just some blinky lights.

I asume you've got some i/c piping to go with the FMIC?

That motor got a good timing belt on it? Now's the time to replace it if it's questionable!

Plugs and some good plug wires?

Don't leave out all the little tune up and maintanance things... that crap can add up in a hurry.

OH, and you'll probably want some spare parts laying around for when you start breaking stuff....

[ncgalant]

Don't buy that puck disc unless you want to break your tranny. The ACT organic disc works very well.

[black92_tsi_awd]

Why do you have a 2G Maft and a 3" GM listed? You only need one.

Will you still need a translator for the GM Maf even with the DSM link?

[BudmannG]

Well guys I have a AFPR and a new timing belt kit to put on it. I just have to buy a tensioner now. Plugs, wires and all the little misc. stuff has not been forgotten about.
As for the way I worded the 2G maft, I was talking about a translator for the 3" GM Mafs. Sorry I confused people, I thought that's what it was called.

Thanks for all the input so far guys.

[turbohcar]

Which AFPR do you have?

[BudmannG]

I am going to run my ebayer unless it shows signs of problems. Then I will buy one that is worth the money.

[turbohcar]

I thought it was giving you problems at the track?

[BudmannG]

I am thinking it was an ECU problem in my 91, not sure until I can play with it.

I did have a interesting question threw at me today. Why a GM Mafs? I replied that I prefer the blow through setup to the draw setup. Then they asked what the benifits were to having it over a stock 1g or 2g mafs. I don't know the answer to that question. Could someone answer that for me? I like the blow through for the bov being able to be open atmosphere.

[natedogg]

When you start running big boost and large airflow, you'll run into the upper limits of the 2G and especially 1G MAFs metering ability.

[turbohcar]

From what I understand, the limit of the 2G stock MAF is around 400hp. The 2G flows 30% more air than the stock 1G. The GM MAF is a lot less restrictive and still allows you to run the Karmann style sensor in conjunction with the stock computer. The 1G sensor tends to be a major restriction, even on the stock turbo.

BTW, I've got a hacked (properly) 2G MAF with a cone filter kit, and hard intake pipe that fit directly on your car. $50 for you, I bought it for $75. If it doesn't work, I'll send you your money back.

[BudmannG]

No thanks Brett. I have a Gm Mafs already. I guess I just confused everyone with the way I said 2G maft. I meant to say 2g gm maf translator. But I do appreciate the offer man and the deal.
Are you supposed to take the honeycomb out off the GM mafs? I see in sale ads where everyone states that IT STILL HAS HONEYCOMBS.

[The Iron Goat]

No, don't take that out. It works just fine and dandy the way it comes to you.

[BudmannG]

Thanks Goat! It's setting on top of my fish tank right now. And I have been stairing at sence I got it over a month ago.

The GM MAF works essentially the same way the stock MAFs do. The screen has to straighten the vortexs' in order for the sensor to read them correctly.

Thanks Brett, You also helped me figure out how it goes in, LOL. I appreciate your help man.
What is a good set of plug wire to get?

[99Spyder]

What is a good set of plug wire to get?

Magnecor wires seem to have a good rep. I have the 8.5mm wires and I think they added like 75hp because they are red!

[turbohcar]

Honestly, it depends on what you believe in. I'm a man of physics (or I like to think so). There is a spark plug wire thread in DSMTuners that illustrates an independent test of different wires by one of the members. The conclusion? MSD offers the best wire in terms of the least resistance, followed by Accel's high end wires(which are the ones that I have, $70 wires). Magnacore was one of the worst, but it had one of the best radio suppression ratings. Radio suppression keeps the electronics in your car from getting fried by the radio frequency spark energy produces (this is how I understand it) but with good suppression comes a price, which is resistance. The lower the resistance, the more spark energy the wire can transmit.

Actually that's not quite correct. The stock MAFs are Karman Vortex meters that work by using a sonic signal across the plenum inside the MAF. The variance of the sonic reading shows how much air is flowing through the MAF. This kind of MAF also requires an integrated temp and baro pressure sensor.

A GM MAF is a hotwire MAF. It is constantly trying to keep its wire(s) at a constant temperature. The voltage that it has to supply to the wire to keep it at its preset temperature determines airflow, air temp, and air density all at the same time. The cooler the air molecules, the more the air molecules, or the denser the air molecules, the more voltage will be supplied to keep that wire hot.

This analog voltage signal is seen by the translator which converts it to the frequency signal that our stock MAF would normally output so the DSM ECU has the correct input for mass air flow.

[turbohcar]

Whoops! Looks like I've stumbled across some misinformation again. Thanks for the correction Nate.
