So I am going for a 02-04 pi engine swap for my 98gt, MY question is when I drop the pi engine into my 98gt when I start lookin for mods am I gonna have to look for mods for the 02-04 4.6gt and not 96-98 4.6gt anymore ??? for example on the stage 1 clutch from spec i was gonna get for my 98gt is just for 96-98 gts, and they also have a specific stage 1 spec clutch for the 02-04 gts. In other words should I jus wait on mods for my new engine? unless of course mods are for 96-04 4.6 gt, then I shouldnt have to worry and go ahead and buy them then jus switch them over to my new PI engine.

well the clutch deal is becasue they had different trannies those years. you just need to know what tranny you have and buy the clutch for that. as for other mods, yeah youll need to buy them for the year engine you put into the car. and ya if its for all the modular motors, dont worry cuz they should interchange

awesome, thanx.......guess wut i found a 2004 gt engine for just $3,000 and 8 freakin miles, yea i said 8 freakin miles!!!!!!!!! i was like , too bad i dont have the money yet. thanx once again.

Yeah most parts for the modular motors will swap over...

You have a T-5 tranny do you need to buy the clutch for the T-5 (your year of car)...


Thats one hell of a deal on that engine...

yea i either have the t-5 or t-45, havent checked on that vin # on the side of my door. but yea something i dont mind spendin on is a clutch cause i need it and i wont be gettin my pi engine for a couple months from now and it woulndt be good to wait that long, lol.

btw trannys change mid 01- and up so i will probably need a tranny from mid01- and up for my new engine huh ????

5.0 = t-5

early 4.6 - 01 1/2 = t-45

4.6 + = t3650 + t56

I will take that as a yes, lol. ( yes, to me havin to get tranny t-3650 )

so i wouldnt be able to use my t-45 tranny with my pi engine 02-04 ???

[Casper98GT]

you dont need to get another tranny.

then usin my t-45 with a 02-04 pi engine should be fine since they both 5 spds ? I wanted to know why FORD switched to the t-3650 tranny in 01 + gt's ? thanx btw.

[Casper98GT]

elec. assist reverse. T-45 has problems with reverse. So they revised it, along with syncro's. Much better tranny, in their eyes. some people have their tr3650 still and have no problems... the other 80 % of people say they are shit and ford knew they had a problem so they input a tsb for new parts internally in the trans. Only problem with our t-45 is reverse problems and syncros go quite often.

i think u did a typo in----- " some people have their tr3650 still and have no problems... the other 80 % of people say they are shit and ford knew they had..."----- I think u meant t-45, anyways I think i will get my new pi engine with a t-3650 tranny then, cause you are right about t-45s havin problems with reverse as i do, it dont go in how it should when ur shiftin i gotta shift it hard in R or if i do it smoothly like when i shift it freakin grinds or dont go in at all.

[Casper98GT]

You think im a newb boy!!! Im a ford tech. trust me.... people have lots of problems with their t3650's.

haha. i like my t-45, never had a problem with it. Few times when its cold doesnt like reverse. But oh well.

oh guess I was wrong about your typo, my bad. I will keep my t-45 tranny then, is there anyway I can fix my problem tho, maybe I need a new shifter, short shifter of course.

[Casper98GT]

i have found go to 1st then reverse. works everytime. :wink

i dunno i might hit the car in front of me if I put it into 1st first and that wouldnt be good.

[Drgnracin72]

ive heard lots of problems getting the 3650 into 3rd gear under hard accelaeration.wel if you put it inot first dont let the clutch out

[ChrisJ]

Oops sorry about that...

It was a long night and I was thinking t-5 for some reason...

I have had issues with 3rd gear in my car...Its not all the time though...Sometimes when I am putting the spurs to the car it will do it but not all the time...

[98vortech]

so i did this swap in my 98 gt...you will need motor, heads, as i got mine from dss racing...the pro mod 4.6 and i upgraded my heads..i got the pi intake manifold had it prted to mach the heads. i went ahead and got new longtubrs,clutch, fidanza flywheel. plenum and tb.i used my stock oil pan, valve covers, timing cover but i painted them so they looked presentable..new injectors, lines, rails. my tranny and bell housing bolted right up with no problems but it is a tremec but it shouldnt matter....good luck pm for any questions..

I have allready done the swap in mine. This is what U need to know. Keep the water pump off of your old motor and the pully. the pump is a differnt lenth on the newer motors. If U plan to keep the stock pcm and wiring harness, (stick with coil packs) U will need to swap the timming chain cover to keep the mouting points for them. U will need to drill and tap a hole near the t-stat housing for the coolant temp sensor that goes in that position in your old motor. If U still wish to use a 10.5 clutch, use the flywheel from the old motor, the olny difference between the older one and the newer ones is the bolt pattern and pin pattern for the pressure plate.

I hope that this helps, John C

why, do the 02-04 gt models use a clutch different from a 10.5 ????
