We would like to introduce to you our new MTK Kit. The MTK Series was designed to install Honda’s newer K Series engine into the Classic Mini (1959-2000), upgrading the Classic Minis A-Series engine with today’s most trusted engines built by Honda. With nearly six times the horsepower of a stock Mini 850, you might understand one good reason for the swap. Reliability and knowing that your car will crank and run in any condition is another great reason. Have fun with your Classic Mini.
Mini Mania has taken all of the headaches out of this engine swap by developing the MTK subframe. Specifically designed for the Mini and the Honda K20 engine, the MTK subframe mounts directly to the Mini using the two stock Mini tower front subframe mounting bolts, then the Honda engine mounts directly to the subframe using the hardware and brackets that are supplied with the Kit. It is as simple as that!
The MTK Kit comes with the upper and lower suspension arms. And, they are custom made just for the MTK Kit, so no more 1959 antique suspension on your Mini. Our new kit also comes with the axle shafts that you will need to cross over your Mini CV joint to the Honda joint. Other items included as well (photo Coming Soon). The All New MTK Series Kit from Mini Tec means out with the old slow bumpy ride and in with the new smooth Super Fast ride! MTK Kit Includes: MTK Subframe, RH and LH Upper Suspension Arms, RH and LH Adjustable Lower Suspension Arms, Engine Mounting Brackets, Transmission Mounting Brackets, 2 Custom Hybrid Chromoly 400hp Axle Shafts , Replacement Steering Arms (these arms are extended for better control at high speeds), Detachable Cross-member Bar for extra strength, and all of the Hardware and Instructions that you will need for the Honda K20 Installation. All subframes come in black.

Dear Customer,We welcome you to the Honda Powered Mini World. Thank you and Congratulations for your purchase. You can be certain that you have made a wise choice with this upgrade. This kit was designed to help put you on the right track when building your ultimate Mini. With the help of this MTK Kit, you will be driving your Super Fast Mini soon.Mini has been made in many variations with many subtle “tweaks” and varying build quality over its lifetime. It is impossible to account for all these, and some will even be unique to your car. Additionally, your car is likely 15+ years old, with all that has happened to it in that time.With all that said, your MTK kit and these instructions are designed to try to allow for some of these differences. For others, you will have to “field fit” or adjust as you go. We’ll do all we can to help keep your project moving along. Please keep in mind that pictures will be of great help, so if you don’t have a digital camera, (or always wanted one) now is a good time to get one. In fact, you should take LOTS of pictures to document your project. Your project may seem overwhelming at times, but if you take it one step at a time, in a logical sequence and take an occasional break from it, you’ll do great.The purpose of this kit is to make your Honda VTEC installation easy and hassle free. We have taken the research and development headaches out of the install so that you do not have to deal with all of that. The sub-frame mounts to the car. The engine mounts to the sub-frame. And after a few other small connections, you are ready to crank and drive your Super Fast Mini. We have broken the whole VTEC Mini build up into sections, from start to finish. We hope that this will be a pleasurable experience for you and we will do everything that we can to make it that. Just remember, we are available to help you 5 days a week. Just give us a call or drop us an email.Thanks and have fun,

Step 2: Whether you use Mini Tec’s MT Flip Front End Kit or you do an extension yourself, you will need to cut existing Mini front end after the a-panel seem to remove existing Mini front. See Figure 1-2. Note: For extended metal front ends, it is best to attach the MTK subframe first before performing any body extensions. Step 3: Clean, Prepare, and Prime the cars firewall and all ruff surfaces (See Figure 1-3). Note: Add additional metal for extra stiffness to the front side of the a-panel as shown in the photo below. A guide tab on the inside of the a-panel will help align the MT Flip Front End as it closes.
Step 3: Cut out metal just below stock shock mount. This is needed to fit the MTK subframe (See following two photos).
Your Mini should now be prepared for the installation process. Step 1: Attach upper bump stops. Mini bump stops with the single stud will work here. Step 2: Attach the subframe to the car using the two large subframe mounting bolts just like the standard Mini subframe. If your car is an earlier model and does not have these two large ¾” diameter bolts, then you will need Mini Tec’s MK1/2 Subframe Mounting Kit (#351000). Standard Mini mounting bolts are circled in red in the following photo. Do not tighten completely at this point. You will need to attach the subframe and the bottom first. Step 3: Drill six holes to support the bottom of the subframe using a 5/16” drill bit. Use the six supplied 5/16” bolts with plates to fasten the subframe to the car on the lower side. The plates will go inside of the car to give the floor panel extra support. After the six bolts are in place and tightened, tighten the two large subframe mounting bolts on top of the frame. See photos.
Your subframe should now be attached to your Mini.Installing Engine into Subframe:Step 1: Drill stock B Series Honda engine and transmission mounts to ½”.Step 2: Attach supplied transmission mount adaptor plate using the supplied hardware in the sequence that it is attached to the plate. Then attach Honda B Series transmission mount to transmission. Step 3: Attach Honda B Series engine mount (#210280) to MTK frame as shown. Make sure that your mount is for a Honda DC chassis. Step 4: Attach MTK engine mounting bracket to engine block as shown. For some engines, you will need to use the supplied spacer plates for clearance. Step 5: Lower engine into subframe and attach it with the hardware provided.Step 6: Connect rear engine stabilizer to transmission as it is aligned on frame.Step 7: Connect and tighten front engine stabilizer bar as it is aligned on frame. Axles: Assembly and InstallationParts needed for Assembly: *Chromoly Axle Shafts, Complete Inner Honda CV Joint Assemblies, and Complete Outer Mini CV Joint Assemblies. (See Photo Below)

Route all brake lines along the contour of the MTK Subframe. Coil-Over Shock Installation:Step 1: Attach lower side of shock as shown in photos. Step 2: Attach top shock to upper strut mount. See Photo. Fuel System: Change your fuel pump to one that ranges from 32 to 48 PSI. A return line will be needed on certain models that do not have them. An inline fuel pressure regulator will also be required to set your system at 45psi. Cooling System:The MTK Subframe is designed to use the Honda Civic radiator 1992 – 1998 model but, slightly modified. The bottom port must be cut off and relocated to the bottom side of the radiator. There are two tabs located on the front of the subframe for mounting this radiator.Alternative: Mini Tec MTK Aluminum Radiator Kit comes with everything you need to keep your Honda Mini running at the correct operating temperature.
