V6 conversion help!

[Big_T]

OK so im making this thread because there are WAY to many rumors out there about the V6 conversion.

Background: Im building a 302 block and have been looking for a great shell to put it in. I found a good candidate, but its a 95 v6.

Questions: What do i NEED to get the car to run? What would i WANT to replace after i get it running?

Clearly the things i would NEED are the Engine, trans, wiring harness, and ecu.

What about the little things, i was told that the fuel lines are different on the V6 vs the V8, true or false?
Does the gauge cluster need to be swapped out? im assuming yes.
Brake system? i have been told yes and no.
the rear end i know is a 7.5 and i will want to swap in the 8.8 rear but its not a necessity.
Also suspension. i have been told the k members are different and the springs are softer, true or false?
Radiators the same? alternator the same? steering pump the same? WHO NEEDS A/C AND SMOG!
ALSO something i never heard anything about but would i need to weld exhaust hangers on 1/2 the car seeing as how the V6 only had a one side exhaust?! im assuming so.

Any info on this topic would be GREAT before this shell gets sold to someone else! Thanks guys!!! remember facts are more helpful than rumors!!!

you going carb or efi?

Alright, being that it's a 95 v6, the k member should work just fine for a 302 application.

What about the little things, i was told that the fuel lines are different on the V6 vs the V8, true or false?
I'm not sure on this one, I don't know if the single port cars were returnless or return style. The v8 cars would be return style.

Does the gauge cluster need to be swapped out? im assuming yes.
Yessir

Brake system? i have been told yes and no.
No, if anything, switch to 99+ V6 calipers. All you need.

The rear end i know is a 7.5 and i will want to swap in the 8.8 rear but its not a necessity.
True.

Also suspension. i have been told the k members are different and the springs are softer, true or false?
I went over the K member thing earlier. The GT springs have a stiffer rate to support the extra weight.

Radiators the same? alternator the same? steering pump the same? WHO NEEDS A/C AND SMOG!
Not personally sure on these things. I know they are similar at least

ALSO something i never heard anything about but would i need to weld exhaust hangers on 1/2 the car seeing as how the V6 only had a one side exhaust?! im assuming so.

The holes were there on mine, just nothing in them

Efi. My friend was telling me that on the v6 mustangs that he was looking at in junkyards the fuel lines were ran differently than the v8 that me and him owned.
And what do you mean holes for the exhaust?

 

[g36 monkey]

All the holes to bolt up hangers should be there. And, pre 98 the fuel systems probably are different.








..... I stress..ALL of the holes

 

[Big_T]

Can anyone confirm the fuel systems are different between the 95 v6 and v8?
also dont you need to swap out the brake booster?

 

[Big_T]

Found this on a fourm.

This is for all u guys who want to get rid of your lazy V6, for that V8...there has been alot of info posted on other sites about how to do it and what things you'll need but they are so mis informative it's not even funny!!..im gonna list all the parts i needed to do my swap, and give a few tips on how to avoid problems!!

parts:

1. engine...94-95
2. All under hood wiring...CCRM,Computer,Fuse box injector harness....(Getting everything from one car is the easiet but not always available) Computer located on passenger side kick panel...wires run thorught the firewall, into fender (Gotta take out fenderwell)
3.GT bellhousing....LOOKs the same but there not
4.u can reuse your altenator and starter
5. New flywheel and clutch...V8 uses 10.5 inch flyweel and clutch...V6 uses 11inch..thats why the bellhousing is different...(The hole for the starter is 1/4 of an inch in..that the only difference)
6. Electric fan can be reused
7.Need V8 throttle cable
8.V8 springs...keep it safe
9.exhaust (whatever one u like....make sure u get the exhaust hangers for the passenger side as the V6 doesn't have them)
10. Flywheel bolts....different thinkness of flywheel
12 **MAKE SURE u get the "Calibration code" off the door of the car that u get your computer from becasue u need this to buy sensors.
13..Secondary A.I.R U will need the tube that runs from the engine bay down to the catalytic converter on your new V8 exhaust (discontinued)
14. If your car is equipped with A/C...you will need longer AC lines
15. You will need V8 power steerting lines as the V6 one are to short
16. I reused my V6 powersteering pump but i would suggest getting the V8 pump
17.Fuel pumps are the same
18.MAF sensor can be reuesed as both 3.8L and 5.0L use 19lb injectors
19.You will need the intake tube for the V8 or just buy an aftermarket CAI (Discontined)
20.If u want u can get a V8 gauge cluster as the orignal tach will not work with the V6 gauge cluster....i went with an aftermarket tach
21. 5.0L mustangs use the AIR system...u will need to get the 2 check valves from FORD....(calibration code needed)
21.you will need 2 oxygen sensors
22. The radiators are the same
23.Brakes are the same on V6 and GT
24. If your engine doesn;t have engine mounts you will need V8 engine mounts.
25. Im not 100% positve but i think u need a carbon canister and V8 vacuum lines
26. The rear-end will work but i wouldn't suggest pounding on it to hard....(Dont dump the clutch) some say it will be fine..others say it will break the spyder gears...i lit up the Tire and the rear-end howled really loud..i let up pretty quick...find an 8.8 and put it in.
27. Lower control arm bushing....unless u can get the control arms off easy..Check balljoints at that time too...(no point in putting it back together with bad parts)
28. Make sure that the computer will match your transmission (5speed tranny..ask for a 5-speed computer)
CCRM= Contsant control relay module..the V6 one will not turn on the electric fan with the V8 computer...make sure u change it...the car will run with the V6 but NO FAN!!
this part is located on the overFlow bottle
29. Now is a good time to replace your clutch cable. If your is streched it would be better to replace it now!
30. You will need fuel lines. (Discontinued)
31. You will need the molded hoses for the AIR system . Discontinued

Discontinued= FORD doesn't stock it anymore

Im pretty sure that is everything i needed...Most important is the Calibration code...i didn;t have that and I couldn't get Oxygen sensors, i found the VIN number from the car that my computer came from and ran it a FORD....luckily the calibration code came up!

Anyone have some input on this?!

That list sounds right.... and all that for a V8.

Technically the 302 swap is not street legal in the US if you use a Mustang 302 from 94/95. The V6 is OBD II and the GT was OBD I. You can't legally swap an OBD I controlled motor into an OBD II OEM street car. You would have to use the 5.0L out of the newer Explorer.

Unless you are dropping in a built V8 (450 hp or more), there are cheaper and easier ways to make power out of the current motor.

 

[Big_T]

my 302 is from a 89 Lincoln town car funny enough. but its completely built. im planning on 350RWHP. But this is the first im hearing about the 95 v6's being OBDII. If thats truly the case then i will NEED a GT.

 

[whiplash473]

Why can't more threads be this good?

 

[Big_T]

sarcasm? haha

 

[whiplash473]

Not an ounce of sarcasm. This thread is like something out of a textbook for Tech Sections on forums.

 

[Big_T]

How to V8!
step one: BUY A V8 and dont convert!
step 2: If you must convert.... Convert to a V8!
LOL

 

[whiplash473]

Step 3: Once V8 is achieved, don't go for more cylinders, go for more cubes.

 

[Big_T]

step 4: SUPERCHARGE!
