3.0 Build Project: "Green Machine"

[Ondonti]

How much did they run you for that plate? I think a lot of people bore too large to use that.

[MC#4]

The plate was $200 which is alot easier to swallow compared to about $500 to buy a premade one.

As far as boring size, it ended up being a compromise between my useability and versatility. The holes are about 3.670 or about .080 over. If the holes are too big it doesn't compress the firering on a stock gasket correctly and kinda defeats the purpose. The plate was made to be effective for stock-.060 over which is the range I intend to use it in.


Of course none of this really matters since my project is stalled for a while. I hate to say it but I might not be able to do much until I sell my bike this spring.

[Ondonti]

But you have some sweet aluminum hanging around :P

Well I got my ECU back from Shel-game. Just curious, are there any other socketed 3.0 ecu's out there?


After a series of emails I decided to go with a 7k rev limiter and an absurdly high speed limiter. (255mph) He says that the ECU will run the same map at 7k as it does at 6k but the factory map is very conservative at 6k. My big plan was to run the cams that were in rick lozier's daytona but looks like I'll be stuck with stock for a while due to money issues. The only things I gained is I "might" be able to go through the traps in high 3rd gear instead of shifting into 4th right before the finish line and maybe now my cousins TT stealth won't pull quite as many bus lengths on the highway as I stayed back bouncing off my stupid 118mph speed limiter.

I pulled my car into the garage today ready to pull the heads, and replace all the gaskets. I stopped at the local dodge dealer and they wanted $75ea. for head gaskets! I ordered a full fel-pro set on ebay for $77shipped. I would have much rather stayed oem but I'm not making serious power anyway. I'll be dropping the heads off at the machine shop to get them checked for cracks, warpage and probably new valve seals. Looks like This car may end up a driver/weekend racer for a while. I really wanted it to be a more dedicated race/cruise type of car but so it goes.




Here it is ready to go. I just need to find some motivation, I'm sure I left it around here somewhere.....
Note: I have the airbox off to start tearing down, I was running with it all hooked up. The thing on the driver's side strut tower is my line lock.

Riding 3rd gear through the traps should get you a little ET. I know on my dynasty 3rd hits 5800 limiter around 85-87 on stock speedo (who knows how far off that is) but i expect it to trap around there so i would probably be losing out on something in the last second of the run whether i rode the limiter or shifted.

best oem headgasket would be the one bought from Mitsubishi for a twin turbo stealth/3000

i would be concerned about the tune above 6000rpms. rick's cam is good for the stock power band, not sure about after 6000rpms though. even then.. its going to lean out i would guesssss if the cam still flowed up there. did he do anything to your timing?

[turbovanman²]

I would have put the rev limiter as high as possible, then you can use your right foot as needed,

[MC#4]

Yeah I would have liked to stay oem, I just need to get this car running right now. I'm moving soon and also out of a job. I have kind of a unique situation as far as maps go. I have some control over rich/lean with my nitrous jets so If it happens to go lean after 6k, I'll bump up to the next size fuel jet. I don't plan on hitting 7k on the street anyway so the only time I'll see those kind of rpm's will be at the track w/nitrous. I have a wideband and I'll be sure to report the results when I get it running.

I didn't have him change anything with the timing. I'll be honest, I didn't want to induce any more unknown variables just yet and like I said I really need the car running and its the only ecu I've got so I needed to get it back from him asap.

[Sundance 6g72]

you can always run a piggy back for cheep. the s-afc can be had for cheep i think if you look on 3s and dsm tuners.. that is if it ends up being a problem. If you dont have the cams yet.. i would try and get one that will make power to the 7000rpm and then fine tune with the s-afc or some other piggy back if need be.. but no job probably means halt on car stuff. i know how that goes

but then you cant ride the limiter like a ricer!

[turbovanman²]

True, sort of, lol. My old Quad 4 would tag the 6800 limiter with ease after I modded it, was bloody annoying, it was just coming alive then BANG, 2nd gear was the worst,

[Ondonti]

Its nice having a rev limiter when you have traction problems. Terrible idea to go without one. A camshaft would help the tune above 6000 rpms.

I would have just bought 2 new felpro headgaskets and reused your stock headbolts. I don't know anything about the quality of Felpro bolts for our motor and how they compare with OEM.

[MC#4]

When I said complete kit, I meant a complete gasket kit, Includes head gaskets, intake gaskets, valve seas, exhaust gaskets. Basically every gasket for the top end. I will be reusing stock head bolts, Even if they came in the kit I wouldn't use crap aftermarket bolts.

I'm glad I kept the rev limiter. When I was testing my nitrous on the street, I launched and spun like CRAZY and the nitrous blew right by the 5800 rev limiter since it has its own fuel supply. Factory tach went up to about 6800 before I could let up.

[Sundance 6g72]

Haha damn


I used the felpro top end set too. Havnt had a problem

[Ondonti]

Definitely not a bad price when you want to replace everything. Each one of those gaskets is about 20 bucks so you get one thing about free

Several people (myself included) have reved the stock bottom end to 7500 without a problem. So 7000 should be safe.

[Sundance 6g72]

the valve springs might not be happy at that rpm though (if they are still stock). i think i *heard* valve float at like 7200rpms on stock everything.. i set my limiter to around 6500 these days but thats still to high for my cam.

[Ondonti]

Yup, valvetrain is the limit, not the bottom end.

[MC#4]

I've got a few things done in the past week or so.


I'm feeling pretty confident that my heads are going to be ok after all. Looks like the head gasket just failed from age. The gasket material around the firering is deteriorated. I've got both heads off the car and taking them to the machine shop this week for cleaning and pressure testing. I'm also in the process of deleting A/C for weight and more underhood room. I really miss driving this car. It's been down for 2 1/2 months.

Actually, the speed limiter is even more absurd than that. Because of some differences in the code, I had to change the speed reference value to the raw speed. Which means that the speed limiter is actualy like 1020mph, lol. Good luck hitting that one...

[RoadWarrior222]

Ahhh fresh challenges
