That is just gear ratios. The stock TR3650 has a 3.38:1 1st gear and .68:1 5th gear. It's the same as ring and pinion ratios in that the higher the number, the easier it is for the engine to turn but you will turn at a higher rpm. A brand new TKO600 costs around $1,900 so a used one is your best bet for price.

the TKO is gonna handle ALOT more abuse!!! the 3650 came out in 99 or 00 GT's. the TKO is not a factory option. it is built by Tremec trans. but a TKO600 should handle all you wanna throw at it

so your telling me to go with the TKO from Tremec...ok then i'll have to look into that one...and also get the kit from someone to change from auto-man....i just hope it's going to be worth it...i do think it is...but you know how it is just want to make sure before i go out and do this...and i'm really looking forward to when i return from WestPac...and put my car in the shop to get that 5.4 installed...it's going to be a blast...i just wonder how much hp they're going to get out of it...thanks for taking the time to read this...

yea should be really nice, hey guys.......Big question. Was the 5.4 2v in a 99 a pi or npi. I got a guy that is trying to sell me a 99 complete motor that just locked up but when he loosened up the rod caps it turned freely so i'm guessing replace the crank and rods which i was going to do anyway. 
Just let me know thanks.

Void, that was a NPI engine, the switch came later i believe in 00. Also, Stang671, I wasn't saying to get a TR3650 (which is better than a T45 since it handles more, people just say that because of the TSB), but rather to get a used TKO. I was just using the TR3650 as an example for ratios. A lower ratio is more ideal for the 5.4 due to the torque.

so much to cover so little time.
tko600 is about the beefiest tranny you can get in a 5 speed that'll bolt up with minimal hassle. it'll easily handle 600lbs of torque which a monster 5.4 with a blower and or nitrous is well capable of delivering at shockingly low rpm. if the power came on at higher rpm it wouldn't be so bad but it don't so we have to think about tq loads as a serious factor in tranny choice.
PI came out in the 00 model year on 5.4's and mostly in 99 on the car lines. Any ol 5.4L will do as a block donor. GT supercar motors are excepted but if you've got 34 grand for a motor you don't need my help.
Void that motor is toast. Pass and go on to the next one. Don't start yourself wiht a problem. If a rod bearing is tapping that's one thing but this bitch locked up. you can't tell what's really wrong till you try to put it back together.
in general, for street cars that are driven on the street more than the track I recommend 3.55 gears. They keep the 5.4 in the tq band without winding it out and you don't have nearly the problems with traction that 3.73's and bigger will deliver. Saleen S 330 had mad traction problems with big tires on a heavy car with 3.73's... he couldn't get it to hook before 4th gear.
I like a 2.95 first gear with the 5.4 because you can do 45 in first gear if you want (which would be very loud and ticket worthy), it reduces the tq advantage on 1st gear so when you go from a stop in the rain you're not spinning till hell won't have it, and I pick the .62 5th to keep your gas mileage somewhere near stock when you're cruising the highway at sane speeds.

if it's only 100 bucks then it might be worth it for the all the nuts and bolts you will need along with a timing cover and a block to be machined if it didn't score it to bad when it locked up.
#1366
03-20-2007, 12:46 PM
i might still get it but i'm going to have to get some pi heads. i don't know, if it turns freely when the rod caps are loose then probably i just need to get a rebuild and then a new rotating assy. right?

most important is to strip the block down and take it to a machine shop for cleaning and inspection
#1369

i would if it's only 100 bucks. i spent that on little stuff that i needed to assemble the engine. i would go ahead and have it bored .020" over and if the main bearings need to be done .010" over i would since it did lockup on the owner. the bearings and pistons won't cost that much more for bigger and it would insure a good block to buildup.

that's true. If it's complete from intake to oil pan you can definitely use most of the little parts that would otherwise cost you a bunch if bought new.
edit.. hell if it's got a front cover you've paid for it for 100 bucks... front cover costs like 250 or more retail.

With most of you guys' setup or ruffly around that would you be able to beat the new competition (chevy-dodge), and most imports...talking NA...or do we really need the SC/TC to help us out...I'm wondering if we can do it NA to NA...thanks for taking the time to read this...

every year the stakes are raised. playing catch up is for the birds. so... the new thing will always bring more stomp to the table. What it won't bring is anymore value to those of us that just want the most out of what we have.
I doubt there'll be many stock cars that'll have the gumption to take me once the 5.4 and nearly 200hp worth of nitrous are in full roar. Those that can take me at that point can have the glory... I don't want it.
BTW... our combos vary as widely as our locations. Some are pretty extreme, some are fairly mundane. Mine is what I'd call moderate. The motor is built to handle the driver and not so much the power.

looks like it should be about like mine but i just read something that worries me. You put full syn. in your 5speed......bad bad bad. It messes them up from what i've read on many many other post. just letting you know, and how is that t45 holding up ??? just wondering

i'm using mobile1 syn in the t45. who said full syn was bad for it? i don't see how it would hurt my 84k mile tranny. but i'd like to hear what everyone else is using..
#1378
03-21-2007, 06:27 AM
one of the first post i saw when i joined corral was that someone put that in their tranny and everyone on the site including ford techs said that full syn was bad for manuals but good for autos. I'm not sure why i never joined the tread. if i run across it ill link it.

That is the most retarded thing I've ever heard. Maybe to break in a new tranny they were talking about but otherwise it makes no sense. Especially since TREMEC themselves recommends synthetic Mobil 1 ATF.
#1380
03-21-2007, 08:04 AM
I would have to agree, I run fully synthetic in my tranny with no problems. The only thing ive recognized is when its cold I cant slam gears till it warms up but I would expect that period.
