Q. Cannibal vs full kswap

A1. The "Cannibal" utilizes the Toyota E153 (turbo model) transmission with a Honda k20 or k24 using the adapter kit by Hux Racing.

A2. The "Full kswap" will use a Honda k20 or k24 motor and k20 transmission with the motor mount kit from Hux Racing.

 

Q. Why the two versions of kit?

A. We offer an adapter plate to use the Honda k20 or k24 with the Toyota E153 transmission. This transmission has proven itself nearly bullet proof at 700whp levels and has survived in the high 800whp zone. The Honda transmission by comparison will simply not survive even at stock 200whp levels when placed midship with the traction this layout offers. We do offer a mount kit for full kswap guys who already have or are looking to purchase an aftermarket gear set for their Honda trans and besides, there appears to be many Civic kswap guys looking to make the chassis switch.

 

Q. Do you have a plug and play harness for the sw20 k-swap?

A.  Hux Racing sells a service to blend the MR2 and K20a2 harness. Check our wiring info page.

​

Q. What ECU can I use.?

A1. Hondata-probably the first choice if using the Honda trans since you will be able to use the honda speed sensor for launch control and boost by gear.  You will need to address the dash speedo issue at this point.

A2. AEM Infinity 5-this is the ECU I purchased for my personal kswap sw20 . I used the ka24a4 harness and pinned it to the AEM connector.

A3. Haltech PNP for the RSX-another good option as it is set up for the k20/k24 and gives you the ability to swap speed sensors( good for either trans choice)

A4. You can use any ECU you prefer to control the K.  The SW20 wiring is pretty nice in that the motor wiring is fairly seperate from the rest of the chassis wiring. This makes building your own harness far less complicated.  A kswap harness with relays for a Civic would work since the wiring is still routed in the proper direction. An SW20 ECU is mounted in the rear trunk on the left side.

 

Q. What do I do about the radiator lines?

Left side hose

A1. I have chosen to use the water necks that k-tuned sells for the left/upper neck. The k tuned neck can use a stock radiator hose due to its similar placement to the 3sgte.  

A2. You can delete the j-pipe on this side and use a Gates 22703 hose to run from water neck to hard line under car.

 

Right side hose.

The lower neck will require shortening of the under car hard line to simplify the coolant hose routing. 

A1. Point thermostat housing downward and use a universal flex hose from part store.

A2. A 2' universal flex hose from the car parts store can be used to make the lower radiator line connection without modifing the factory hard line.

 

Q. Heater lines ?

A. Simple ,the k will have two heater bungs just like the 3s or 5s you removed.

 It has been found that the 3sgte heater lines sold by TCS work perfectly

 

Q.  What do I do about axles?

A1. The Cannibal swap with theToyota e153 uses the stock turbo axles and nothing custom is needed.

A2. The full kswap with Honda transmission will need to source axles from     www.driveshaftshop.com   . They sell the 5.9's AND 2.9's.

2.9S Part #s  RA90-43X2 and RA90-44X2

5.9s Part #T020-HUX The 5.9s are a kit and include upgraded outer splines and hubs.

A3.  Cheapest route but please read all: The n/a mr2 and the civic/integra share the same axle spline count.  This is a cheap solution doing a full kswap with k20 transmission on a Non turbo MR2.  O'Reilly's (HO-8003) drivers side, (HO-8121) passenger side. Thanks James White for part numbers. Please be aware that there will be very little thread engagement on axle nut due to splined end being short for MR2 use. If you have fitment issue on inboard diameter you might need to confirm part store supplied correct axle.

​

Q. How do I plumb the clutch hydraulic line to the Honda Trans. ( full kswap only)

A.  We sell a custom clutch line for the swap. Easy Peasy

​

Q.  Will I have to modify my trunk wall to make this work?

A.  No, neither kit version requires sheet metal cutting.

​

Q.  What do I do about an exhaust ?

A. You will need to fabricate some plumbing to tie into your exhaust of choice. Most MR2 exhaust systems have a flange at the crossmember and you can easily tie your header or down pipe into it. The sidewinder turbo manifolds found on Civic kswaps has been show to work also.  The stock header found on the k24a2 and k20a2 will fit in the engine bay.

The EP3 header appears to have the closest fitment but will still need some crossmember work.

Q. What do I do about shift linkage ?

A1. The Cannibal kit uses the existing Toyota E153 trans and will need no custom shift linkage.

A2. If using the Honda k20 transmission the most popular solution is the RSX shift box from Hybrid Racing and  a set of Hybrid Racing Race cables for an RSX.  We sell a custom cable bracket for use at the transmission and a low mount Hybrid V3 shift box to complement MR2 interior.

A2b. Source a shifter box and cables from a MK3 MR2 Spyder. You will also need the shifter bracket that Innovative Mounts sells for the kswap MK3 part # 50507.    http://www.sparktecmotorsports.com/imt-50507.html

​

Q. What about air conditioning?

A. There is plenty of room to mount the Honda a.c. compressor. You will need to have a custom set of lines made.

 

Q.  What about the fuel system.

A1. There is 2 ways you can do this.   I am using a GM C5 fuel filter/fuel pressure regulator and a fixed 60psi on my car. This would allow you to run the stock Honda fuel rail in an all motor combo.

A2.  We are working on a simplified solution much like the 2gr swap uses. Please inquire.

A3. Boosted combo. An aftermarket fuel rail and fuel pressure regulator will be needed. You can feed off the stock mr2 fuel filter with an m12x1.25 to #6a.n. fitting. The factory Toyota return line is a simple hose barb.
