2001 and a half

StompinR1 · May 11, 2004

I have a 2001 GT and I've been seeing that some aftermarket stuff fits the 2001 second half and newer and 99 to first half of 2001. Is there a way i can find out which one I have, and also what are some of the differences in the 2001 first half gt's and 2001 2nd half gt's?

00VERT GT · May 11, 2004

i believe the pulley size changed mid way through 2001. not 100% on that. but i think that is all.

Check your driver's door jamb, if it has a "K" under transmission it means you have a T3650 transmission and I believe all the other stuff is changed too. The pulleys and upper intake are different. I also think the MAF may have changed...

Trublu01 · May 11, 2004

In feb 01 Tranny change to 3650 and water pump design change (different Pulley)

StompinR1 · May 11, 2004

obviously then the second half ones are better right?

DarkHorse02GT · May 11, 2004

Doubt any of that makes a real difference in being "better" except maybe the TR-3650. But with the problems people have with them you coulkd argue that too.

Not really. Oh, the compression changed a little in 01 also... Somehow you can tell from the VIN but I don't remember what was what.

My personal preference would be to find one of the earlier 2001's. They still had the T45 gearbox in 'em, which is less-problematic box than the 3650, IMO

i've heard that driver side manihold ball size changed as well

GinoGT · May 11, 2004

Well from 00 to 01 there were quite a few changes. Not things that are obvious (maybe except for driving a T-3650 in really cold weather)

00......................................................01
Windsor engine....................................Romeo
T45 tranny........................................T3650
...........................................Water pump and pulley change
IAT and MAF sensor separate..............MAF and IAT combined
(GT) V6 style hood and sidescoops................new sidescoops, hood scoop, new wing
.....................................................Bullitt wheels (on Premium GTs. 99% of them are Premiums anyway)

The main differences in the two engines are the bolt patterns for the valve covers and the compression ratios.

Trublu01 · May 11, 2004

Gino, you have it wrong my man, this is a comparison from 01-feb01, not 00-01

this info is wrong Geno. My GT is 01(09/15/00), and I have T-45, and windser block

hotmustang331 · May 11, 2004

Is there any change in performance between the two engines and what CR does the 99-01 have vrs the 01-04s.And also,did ford make any changes to the 04s in the underrated performance department just for the heck of it being the last of that body style and the 40th ed?I have heard the the newer 01+s are a little underated and are really at 275HP or so,so I was just wondering if this was true.

GinoGT · May 11, 2004

Whoops, sorry guys. I forgot to note that I was referring to the later part of the 01's, after the change.

You are one of the very, very few who have an 01 and Windsor block, infact, I'd say I can't believe you unless you have seen the W stamped on your block!

PEA · May 12, 2004

the meter and iat r not together on late 01s
,i have one, the big difference is they went to the t 3650 tranny and changed to 11 inch flywheel and clutch as stock not the late 10.5 lol
some other changes to but i forgot,lol sorry

My 8th digit on V.I.N. is "X", which according to Ford racing, means I have windsor block. Mine is made 09/15/00 BTW. One of really early 01
where would stamp on block be? I would like to check it out for sure

Don't trust a Vin letter/number, mine was built in 11/00 and I have a Romeo, infact Kurgan has a 9/00 I beleive and his is a romeo too. The W is stamped on the driverside above the oil pan. Do a search on here (waaayyy back) TJM01 took a pic of it.

mity2 · May 12, 2004

oh WTF? My vin say i have windsor, but my Valve cver have 11bolts, which means I have Romeo...
Nice info Ford racing
