Re: 97 GT 32V Swap

I'm getting really excited! That's the same exhaust I'll be running, Nomad, except with Flow 40 mufflers. I'm still on the look out for C heads because I'm really low on funds right now... but keeping my eyes open. This build is gonna be fun.

Btw here's my slow drive-by at home. :p

Well like I had said you can grab the set of tumble port heads and have them ported and cleaned up that will up the flow. And you can get them from LKQ at a decent price. they can be found from the Continental.

For the "thread issue" people talk about that actually an issue on both 2v and 4v. You can use NGK plugs as there are more threads on the plug to be able to seat better. On my 2v my #2 cyl blew the plug twice. This was from the injector being stuck causing a lean condition that would over heat that hole. Causing a blowout. But when repairing the hole that was damage, I noticed the threads were only about 2/3's damaged. so that means the plug itself does not have the surface contact, to have a strong hold. So the longer NGK plugs would work better to suite the issue. And besides the 03/04 heads had the same issue. It wasn't until 2005 that a replacement was available. And those are specific, making alot of the heads on the used market to be mostly older replaced heads.

Well guys, I got my tune. Seems to run a lot better. The response is great. And the pull.... just say its nice to have the the rev limit up. It seemed to improved low end drivability but not by much. Which can be expected with the head intake setup. Basically down low seems to feel like a stock to mild gt down low but the mid to top forget about it. Maybe looking into a cam change until I go forced inducted. But maybe the winter project.

That's awesome! I'm glad your tune worked out without probs. Is it basically a 93 octane racing tune?

Yup. There are issues though. I was datalogging a drive session and did notice that I had a small miss through the cylinders. I'm going to take the plugs out after work to see if the plugs have been fouled from the excess fuel. Also one O2 doesn't seem to be right. Though I notice a leak from I think a header. Azure I'm telling you man you need to make the trip to fernale and check out mustang alley and the cruise.

I know, there are a few shows I would have wanted to go to, but funds are low and I've been working like a dog lately. Maybe I can check it out next year. I wanted to go to the American Muscle show this past weekend too. You'll have to post some pics from the show.

Shouldn't be but a 4hr drive if that. You can do it. Its Saturday from 7am to 7pm and there is a cruise that's all day going on as well. Head back Saturday night and sleep in sunday

My compression in around 9.8. I kept it low but high enough for decent NA power. My rings are gaped for FI. Everything has been build in anticipation for forced induction.

Have decided which setup you'll go with? There was a guy at the track with Mach1 just like mine with a Kenny Bell. He said his best time was a 13 flat at the track. He must not have a real high boost.

Re: 97 GT 32V Swap

Couple questions: How to you determine your compression ratio? Also; How do you get your compression ratio to move up or down?

Along with that, what do you lose going one way or another? There's the obvious - FI, but I bet there's more.

You want a low compression motor for boost. Compression ratio is determined by combustion chamber volume and quench area. If I remember correctly anyways. Higher cr the higher the octane fuel you need.

Really the only way to get it to move up or down is by the piston type and your heads combustion chamber. Domed pistons will cause a higher compression ratio and dished will lower that.

Shaving heads also changes it.

Compression Calculator (4.6L deck clearance is 0.008 in.)

9.5 -10.5 work well with centrifugal superchargers with intercoolers. If looking to run a twin screw setup or turbo 9.5-8.5 is good. now if you are looking to run the motor at low CR without a power adder then expect a dog. Machs run 10.1:1 and respond well to nitrous as well as 8-10lbs from a centri.

Problem with shaving the heads is the different in height when you try to bolt on the timing cover to much and the alignment of the cover will be an issue. Trust me mine was snug real snug. and had to take a layer off the top. I was reading how azure was talking with a guy that said his tuner believes that his engine has 11:1-12:1 compression causing the issue in tuning. Time for a new tuner. unless that modular 4v has domed pistons, there is not a chance its 11:1 or higher.

Even after the tune, they didn't move it up to ~7000? I've never bounced on the rev limit, but I think it's 7050.

I have to change all the limiters I guess because the ecm doesn't know what gear I'm in.

How hard can you run her now? How many miles since the swap?

Not even a 1000 yet. But I pulled the plugs and checked them they were all tan and good. I did gap them though. See if it helps. The missing that i pick up can be felt while about 2-2.5k rpms like in third or second. but nothing really at idle but the data-log is picking up random spikes its not constant. So Im thinking coils maybe be an issue. Could be something like a ground as well. Heading up to my garage now to change the oil. HAHA I'll take a picture of the first oil change filter I cut it open.

I think he needed a driver mod. watch this vid from procharger the car has a catback and slicks.

I'm heading out to wash my ride. New are still under a water ban so I gots to go to the local spray-it-yourself. I need an oil change too.

Had a great time at the show. By 3pm there were 1100 mustangs. It was a blast. Even met a gentleman that built my car in the Dearborn plant in Michigan. It was funny at all the double takes I got from new edge owners. I was the only Mark swap. I saw on terminator engine swap and a 01 cobra swap. The GT with the 01 engine was a track car. If you want to see the photos, I started a thread with a link to the album. Mustang Alley 2012 I think is what I called it.

Re: 97 GT 32V Swap

So I decided to hook my xcal2 up and try to change the rev limit up. I raised the neu rev up to 7000 and the drive rev up to 6950. Saved it and programmed it. Still nothing. No change, I did it twice with the same out come. So Im not sure what the issue is with it. Wish I had a key to the sct software Id change it on the tune myself. Not sure what the deal is. Still waiting on the tuner. He should just change it on his end and send me the tune. but that would be logic.

How did you get your current tune on your PCM?

Re: 97 GT 32V Swap

Well my tuner sent another tune and changed the limiter to 7k. loaded it up but no dice. I have no idea what this is. I sent a datalog of it happening. Lets see what happens.

Sorry bro, hope they can get you setup soon. Did you have to give them the PCM's serial on the outside of it?
