i have a 86 mustang lx and i am looking for a 20B and am also looking to find out what all is needed to be done to install this engine in my car...
i will be using a t-5 tranny or a tremec alternative and i understand there is an adapter kit for the clutch and bell housing. i am wondering what sort of mods im looking at having to do in order to get this engine installed.... i searched the forum's so im not too sure who to ask....
Thanks

 

You can get the adapter (rotary>>T-5) from Kennedy Engineering. Search Ebay for the 20b. There's almost always one on there.

 

You will need the following;
20b Engine Longblock
you will need to make custom Engine Mounts
you will have to buy the bell housing that you mentioned,
You will need a stand alone EMS to make real power; two popular ones are Haltech E11, and Mictrotech LTX-12
You will want to run new coils with those since you won't have the stock coils
you will need to make custom oil cooler return/send lines
you will need to make custom Radiator send/retunr hoses
You will need a good rad for the heat the 20b will produce
If you are running it turbo you will need a good Front Mount Intercooler
Good Power can be made with a properly tunned 20b engine, since the rest of your car ie tranny, driveshaft, rear end are Ford specific you would have to figure that stuff on your own... I think this plus other little specifics would be a rather interesting car!

 

jreynish... do you know of any good intercoolers (nothing extream like yours) but something decent that would fit infront of my rad.... i can find you the dimensions if that helps.... and what about a wiring harness.... where can i get one of those... are they pricey????

 

you will get a flying lead wiring harness with your stand alone EMS, that does not cost you anything above the cost of the ems package!
as for intercooler I have a custom one I used to use on my car you can have the core that I have and use it if you would like then custom make your pipping!

 

sweet that works... so the ems package comes with a wiring harness... fuse box etc?

Just curious, but why put it in the LX?

Is it because in Saskatchewan, everyone (and I mean EVERYONE!) has a Mustang and thinks it's the fastest car in the world (but generally it's an old 5 litre in bad shape making 200 flywheel hp)

If that's your reason.. go for it! If it's not... it should be!

Kennedy Engineering sells the adaptor kit for the 13B -> T5 conversion (13b adaptor identical to 20b)

 

How about because the LX frame is lighte than that of the GT, otherwise the only difference in the frame is a few cosmetical differences... so what would the difference be? I mean a 20b is alot of power more than a GT! so lets not go critisizing the platform...

 

Id drive a 93 Mustang LX with a 20b any day and a 93 RX7 ls1 as well. But good lord an 86!

 

an 86 is essentially a 93 except for some minor body differences..... the reason for an 86 is:
First of all i have one and second... they aren;t as common as a 87-93 body stye... therefore more unique

 

No no, I'm not dissing the LX chassis, I'm very please he is doing the swap! I would love it.
I was refering to why he chose the Mustang LX chassis -vs- an FC3S TII Chassis.
But really, what I said about SK and Mustang owners there holds true.

 

Hey! You could call it a Rustang!

Sorry, couldn't resist!

GL

 

No no, not a Rustang.......Take the "5.0" badges off and get ones that say "2.0"

 

now what needs to be done as far as clutch assemby goes....

 

Have fun trying to get it to fit in the Mustang subframe. The exhaust will be a super tight fit, not to mention you'd either have to mount the engine REALLY HIGH UP (meaning you need to do super-hackery to the floor to get the trans tunnel higher, and possibly a big huge bulge in the hood) or you'd have to mount it behind the rack (meaning you'd have to do some super-hackery to the firewall and the floor). Come to think of it no matter what, the trans tunnel will need to be raised a lot.

You know, you can bolt in a nice 460 for more reliable power and about the same weight....

 

The 460 won't break in half, will it?

 

where is saskatuan?
please post your progress of the install and pics of possible... very interesting swap

 

It is spelled Saskatchewan, It is above Montana and ND, you could fit about 4 or 5 montana's in Saskatchewan.

Peejay; Why would you think that the engine would not fit? I mean making a new k member would be alot easyer than cutting the firewall of the transtunnel, Please elaborate as to why you seem to think it won't fit?

 

He just doesn't seem to like rotaries anymore.

 

i dont understand why there will be clearance problems with the transmission tunnel... i will be using a transmission that will be a direct bolt on for me....

as far as exhaust clearance.... i don't understand why there would be a problem routing a 3" exhaust through the stock location.... they make 3" kits for the 5.0

 

The problem is if you can get the engine to fit in the bottom. Rotaries are very wide at the bottom, boingers aren't. They also place the transmission very high up compared to boingers.

Normally you can get around this because of the rotary's somewhat short (lengthwise) dimensions, IE stuffing it *between* the crossmember and the firewall, so that you can get the engine low enough so that the transmission isn't way high up. But you're talking about a 20B, which is NOT short, so it will have to sit up above the rack, so the transmission will have to be higher up, so you might have to do some bodywork...

The exhaust is still a problem. I don't remember the rail-to-rail frame width of a Fox-body, but a Mustang II is somewhere around 32-36 inches. (It's been a few years since I had the MII front clip kicking around) An RX-7 is about 42-44". SImply because the engine is wider at the bottom and the exhaust manifold is right there at the bottom as well.

The exhaust pipes aren't the problem, the manifold or headers or turbos *are*. There has to be something connecting the engine and your 3" exhaust pipe!

It might fit width-wise OK in the SN95's though. The reason Ford didn't put the Modular motors in the Foxes was because they drop the body onto the subframe/drivetrain assembly, so the engine has to fit UP through the engine bay. Needed a redesign for the added width, and if a DOHC 4.6 behemoth can fit between the rails, damn near anything can. :grin:

 

so are you saying even with a custom k member a 20b won't fit, and it isn't nearly as wide as a 5.0L, the k memeber would be desinged custom for this exact purpose.
