1991 Mustang LQ9/4L80E swap

[dman]

Ok, i've gotten far enough along on this build to start posting pics without it taking months to see any progress.

The breakdown:

1991 Coupe
LQ9 from a 05 Escalade
02 Z06 cam and springs
LS1 (until new Edelbrock XT intake arrives)
Built 4L80E with manual Trans go conversion
UPR fox 5.0 K member
MSD 6010 coil controller
Megasquirt 1

ok, here come some pics

[dman]

i also removed the factory brake booster and installed this hydroboost

[dman]

here are some pics of the motor installed and mock up of the radiator and accessories

[dman]

the i decided the factory camaro rad wouldn't cut it so i bought a Griffin and had to make room for it

Looks like it is coming along nicely. How much boost are you planning to run on this setup?

[dman]

well, I had good luck with E85 on the ford motor so it's either going to be that or i'll stick with pump 93 and my meth kit. Either way i'm shooting more for a performance goal than a boost goal. So whatever boost level gets me to 150mph in the 1/4 will be the magic number

[dman]

then i worked on trans crossmember. got this done but i may redisign it later. For now it will locate the motor/trans so i can work on the turbo kit

[tj1986c]

That sounds cool. Best of luck to you on your project!! I'm subscribing to this thread so keep us updated.

[dman]

i've gotten alot farther than the pics have shown. just gotta get time to put all the pics up.

hint: turbos are plumbed and ready

[mred]

couldnt use the factory fox body cross member,modify it like you would for a glide.
glide and 4l80 sit in the same location and also if the cross member has ever been modded for the c-4 its even easier.

[dman]

mred- not even close. the motor is set back and the 4L80 is considerably longer than the AODE that was in it. The new trans mount is about 6-8 inches farther back

[dman]

turbos are plumbed. just gotta run the oil feed and drain lines and cold side piping. driver side pics

[dman]

and pass side

with modifications it could have worked with the factory cross member,i have done it,but my motor was sitting in the factory location,any how good luck.

[dman]

but whats the point? the factory x-member would have to be sectioned and stretched back to the point it would sag over time. i actually had the member sectioned about 2" when i put the aode in the car. not so much because of the set back but the pan clearance was an issue, so to go even farther with it would be harder than building from scratch.

here is the DP routing on the pass side snaking thru the k-member. going with coil overs really frees up a ton of space.

Should be pretty fast. I'll be keeping tabs on this build.

Curious. You want to go 150 w/ a stock internal engine?

Twin 70s is good for upwards of around 1000 hp or so if I am not mistaken. A stock internal engine isnt usualy recomended above 600 it seams. One t70 by its self can do that.

[dman]

No, i'm going to take it easy on the stock internals. Just want to get everything done and working on the stock motor. My stock bottom end 5.0 motor went mid 10's @ 134 so i'm expecting atleast high 9's around 140 for now. I'll most likely do rods and pistons before i'll need a parachute

BTW, is that a photoshop 6.0 badge in your avatar?

[Slow5.0.]

Yes it is.

I have a single turbo 6.0 notch.

[dman]

nice. I was going to stick with the single T70 i was running on my 302 but i felt like it would hold me back. So i figured WTF and added another one. I think a single MP T70 can make about 700hp, but with my small exhaust housings i feel they'll support about 1200hp max between them. Gives me room to grow
