1992 SW20 MR2 Honda K-series *Build Thread - Pics inside

Hi Guys,
 
Its Benny here from BYP Racing. We are known for specializing in Honda's and Honda's conversion and in 2016 we'll be tackling a Honda K-series engine conversion into the SW20 MR2 chassis
 
There was alot of things swaying us towards the SW20 MR2 and price point was definitely one of them. Considering you can purchase a chassis for around $3000 - $5000, it offers great value for money for a project car. With its mid rear application, it appeals for drive-ability, traction and the direction of this project car for the workshop

 We have been involved in all forms of motorsports for the past few years and have had cars built for each purpose. There was one form of motorsport lacking which was the street aspect. With the growing market in the street crowd, we knew we had to build a car to appeal to this market. Lets face it, a FWD Honda will never be able to decently put down a big powerplant and RWD is limited to the S2000. 

Chassis
The team looked into opinion of a chassis that is affordable, RWD/Mid rear, easy to find parts, proven chassis. All led to the MR2 SW20 chassis. After doing research for a few weeks, we picked up a very well maintain white SW20 complete car for $2000. 

Powerplant
The elected powerplant is a Honda K20 engine package with a turbocharger for power adder. Our first package will be basic with the aim for 400kw at the rear wheels and 9 sec 1/4mile passes on street radials. 
 
Here was some inspirational link which has made us get involved with this car and build. Im sure some of you guys must of watched it already



 


We'll be keep this build thread updated as the build progress. It will be quite active for the first few weeks since our predicted completion date will for Powercruise in late Feburary. So there is plenty to do in the next few weeks!

Well you are certainly on the right track by choosing MR2 for chassis.  You will also find there are a lot of very experienced blokes on here who I'm sure will be willing to point you in the right direction.
I'm pleased to see you are installing a basic  power unit of 400kw initially to check proof of  concept.
Do keep us posted with your progress.   We like photos.  Lots of photos.   Cheers.

Welcome BYP. i have been impressed with your "giant killer" Hondas over the years on the circuit.
 
There are other mounts out there, but nothing available as easily as the HUx product. NVH GTFO!

As much as we loved to build a circuit MR2, we have our other cars built already for the purpose

You guys probably know more than me, but after looking into the MR2 and the things that HUX Racing has been doing, i believe the MR2 are great bang for buck cars. There challenging cars on the race track but rewarding when driven and set-up correctly

Car Weight approx 1000kg

Reference from HUX Racing facebook page

BYP is the company building the white one and HUX racing are from America Dudeman.

Just out of curiosity, why didn't you go with the factory (turbo) E153 5 speed box? Would of bolted straight in using 3 of the 4 factory mounts and obviously bolted straight up to the hubs/driveshafts and shifter cables.
They are bulletproof but heavy I think compared to a Honda box.

You can reuse the shift cables, but your better off with the turbo shift linkages. Your better off with the honda box for drag racing, e153 boxes are strong, but a bit slow on the shift, with a really old school synchro design. Also you will be saving at least 10kg by using the honda box over the turbo mr2 gearbox, so that plus the k20 over the 3s puts you 50kg up.

Your not going to run a sidewinder styled manifold then im guessing?

You going to run it on a haltech or hondata?

To run the Honda K-series box, ill be changing to the MR2 spyder shifter linkage and shifter box. Im on the hunt for one, so if anyone has one or know someone, please let me know
 
Additional Innovative shifter kit adaptor is also require to run the MR2 spyder shifter cables to the Honda K-series gearbox. 
We havent looked further at the shaft lengths or angles yet. I reckon it will work out fine. Will report back when i have it back on the hoist 

We will be making a custom turbo manifold. We might do a top mount set-up. Will discuss options with the fabricator in the next 2 weeks
 
We will be using the KTUNER ECU. Similar functions to the Hondata. Being a distributor for both, KTUNER has come on board for this project with their newly release end user 2 ECU. For anyone interested, jump onto KTUNER website
