4cyl to 5.0

mustangsoldier · October 29th, 2008, 07:05 PM

can you use the tranny from a 4cyl on a 5.0? also what else do you have to do for the efi conversion

GoodOleBoyzRacin · October 29th, 2008, 09:17 PM

i know somebody who ran a 4cyl t-5 on a 5.0 with 200 shot for a lil over 2 years. just gotta swap the bellhousing to a SBF style. also you will need wiring harness and ECU

fairlane_68 · October 29th, 2008, 09:38 PM

The gears are way different. If you're going to drive it around town, just get a V-8 one.

hmm, i was told something completely different in my thread

4 cylinder T5s are weak and have gear ratios intended for a torqueless 4 cylinder. They suck behind a V8.

BORDEN · October 30th, 2008, 12:38 PM

it will work if your jus driving around town but if your planing on putting down power then the v8 is a must.

superbean · October 30th, 2008, 12:55 PM

yeah gearing sucks balls.

I'm going to run my 4 cyl trans until spring so i can get the clutch and motor broke in.

you need:

sbf bellhousing for t5
clutch fork
5.0 mounts
fly
clutch
different pilot bearing for 4cyl trans > 5.0
thats it.

mustangsoldier · October 30th, 2008, 03:31 PM

ehh i think ill just find a v-8 lol

TheBrat · October 30th, 2008, 03:46 PM

So, lets say you want to swap over a 5L with a carb on it? Do you still have to swap over the main ecu and 5L harness? Or can I just use the 4cyl harness and computer??

R0B0T · October 30th, 2008, 03:55 PM

if its a carbed motor then you can rip the wiring and computer out and throw it away, then just wire everything you need power to...

TheBrat · October 30th, 2008, 04:19 PM

Well than, that saves me a great deal of issues...
So, I just need to swap the trans member, motor mounts, and thats about it...
Is there anything else I should look out for?
Thanks.

Brett!

86_Notch · October 30th, 2008, 07:47 PM

trannys are wierd, i've broken " world class " trannies in 12 sec cars, yet had a 4 cyl trans live for 2 years in a 13.0 car on et streets ( the slicks not radials ) powershifted every day . i didn't put the trans in so i don't know what pilot bearing to use

TheBrat · October 30th, 2008, 08:58 PM

Alright, well, I guess this raises another question.
The 5L I got is out of I beleive a 86 Thunderbird.
I got a carb, intake, and distributor out of I beleive a 79 or 80 Fox that had a 5L..
Will that stuff work together? Or do I need to go shopping?

Brett!

superbean · October 30th, 2008, 09:38 PM

my friend used his t5 out of a thunderbird for a year and a half on an 11 sec car. go figure. nuked his v8 wc in one month.

fakesaleen · November 3rd, 2008, 09:19 AM

if the motor is a roller motor the gear on the distributer will have to be changed also dont forget you will need an inline fuel pump about 15 psi the efi is to much

94myth · November 3rd, 2008, 11:30 AM

I always thought if you used a smaller part on a big part it would just demolish the smaller part...

I always try to keep it simple and save the hassle but it seems some have got this to work before... Your call.

86_Notch · November 3rd, 2008, 07:47 PM

if it is a roller then the thunderbird motor has a different firing order then the mustang motor ( don't ask me how i know )

my boy put a junkyard short block out of a cougar ( same as t bird ) in his mustang and sprayed it into the low 11s ( used a bottle every week ) and it lived for a long time

+ 1 on the distributor gear
