Vision
This car started out as a automtic sr5 with very little rust.
Originally I wanted to do something nobody had done yet in Hawaii.
Before this we had done the 4agze, ae101 20v, and a handfull of
4age swaps into the sr5. I wanted to try the 3sgte swap and keep
it toyota but the prices on upgrade parts are just outrageous
and hard to come by! That's about when one of my friends came
up with the idea (or more like a dare )to put the sr20det in it.
Yeah yeah I know all you ae86 fans are saying it's blasphemy!
love it or hate it...we did it regardless.
Step 1: Dropping it in.
Engine Mount |
To my surprise everything was pretty
straight forward all that needed to be done was make custom
engine mounts and trans mounts to get it in. we decided to
drop the subframe about a 1/2 inch to get a good angle on
the driveshaft, for hood clearance, and so we didin't have
to bang out the trans. tunnel to much. When that was done
we moved the engine and trans as far forward as we could go
just to get the shifter into a place where it wasn't hitting
the e-brake everytime you shift into 2nd,,4th,or reverse,
then Welded the mounts to there new position and ~voila~~
it fits like a glove. |
If you are thinking about trying this swap I would really invest
in getting a manual rack set-up before doing your mounts, it'll
give you waaaay more room to work with especially when it comes
time to fabricate the downpipe, and for extra clearance when replacing
the clutch. Note: I went with a v-mount set-up but this swap should
fit fine with the ae86 radiator in it's stock location.
step 2: wiring the motor.
By far this was one of the easiest motors to wire into the sr5
ae86's. you need to extend the 02 sensor plug, the AFM plug, and
alternator plug. Then hook up a few power and ground wires from
the SR main harness to the Toyota harness and you're done, pretty
simple huh, We thought so.
Note: being the sr5 model is carb. Not EFI, it has no existing
wiring for a fuel pump. So I wired an inlne fuel
pump (see pic below) to a relay instead. If it was
a GTS model you could still wire the harness to turn on an in-tank
pump.

step 3: fabrication
(the fun part, thanks lance!)
Notice how the downpipe just clears the steering shaft and
the frame rail.
|
I would have to say the downpipe is a real
pain in the ass to do.
We started with tracing the pattern of the
stock turbo exhaust gasket and had one cut out. Since
a 3" pipe cannot fit thru the opening between the steering
column and the frame rail we had to use a 2.5 inch pipe
and massage it in there then expand it to 3" at the bottom.
There is very little room for anything to
pass thru, even getting this downpipe
(see pic) on requires us to remove the
steering shaft to gain clearance. A v-band clamp would
have worked out well but unfortunately we didn't have
access to one at the time, so we worked with what we had.
|
The engine mounts are stock sr20det mounts
mounted to a modified ae86 cross-member and the transmission
mount is a solid mount made out of square tubing and ¼
inch flat bar.
The original intercooler set-up wasn't a
v-mount
(see pic), it
was kind of a last minute decision which led us to a lot
more fabrication from placement of the B.O.V.
(see pic) ,to the cooling
lines (see pic), down to the cooler
itself everything had to be re-done in order to fit and
function properly. To fit the shifter
(see pic), a new hole had to be cut into a
fabricated piece of sheetmetal that fits over the transmission
tunnel then welded into place.
Finally the driveshaft was custom made using
the sr20det yoke and the ae86 differential yoke, the stock
Toyota 2 piece driveshaft design was tossed out and the
new unit was made into a 1 piece driveshaft.

the "low-down":
Currently the motor is running with stock internals @ about 9
psi. it feels really good and has a hard time maintaining traction
all the way thru 3rd gear. We haven't had a chance to dyno the
car yet and I am planning to raise the boost to about 14psi and
see what happens.
The car still has a lot more work that needs to be finished up,
unfortunately I rarely find the time to work on it.
My friend is running another sr20det ae86 down here and is currently
hitting about 340 HP to the wheels stock internals. I probably
won't be going to that extreme...yet. You can check out his car

myself it should be pretty interesting. I will also be posting
the dyno run.
