Darren's 1978 Honda Civic Drag Racer

Darren is an Automotive teacher in Calgary Alberta

It is a 78 with a 1990 Honda Civic SI engine. This is a fast and fun car to drive. Darren grew up on a farm in Saskatchewan, graduated and moved to Winnipeg where he acquired an Industrial Arts/Technology Education Degree. (simply put a "shop teacher"). After graduation he started his 78 project.

In the summer of 2001 Darren was looking for a good teaching job. He was waiting for the perfect job. While Darren was waiting he had time for a project. It was a 1st generation civic with fuel injection. He has owned many 1st generation Honda Civics before, they were underpowered and often ran poorly due to the carburetors. Darren wanted to run a newer engine to gain access to the readily available aftermarket parts. So he decided to tackle one of the projects on his list. Some of the others on the list include a 5.0 Miata (aka Monster Miata), 5.0-4x4 ranger, 92-95 civic hatch with a GSR 1.8 dohc, and the list goes on and on. So these future projects are on hold until he comes across the perfect deal.

He finished up all the loose ends and got it running.... momentarily until the engine seized. I think the car was run upside-down to long. So there it sat, Darren was bugging Trevor to sell it to him for about 6 months. Finally he sold it to him, he wanted to see it fuel injected.

Darren:

So I began the project. Back then I did not know of anyone who has attempted this feat. I knew a guy (Cam from CWS Tuning in Regina) who did the same swap but he used Webber carburetors. I had no idea if the 89 motor would fit with the fuel injection intake manifold. Within the early stages of the project I acquired another 89 SI and 78 for parts. This was great, I could leave one 89 parts car together and use the other 89 engine for fitting purposes.

With the new addition of a 78 parts car I would now name it my practice car. I took the 89 test fit engine and hung it above the practice car. I asked myself what is it going to take to get this in? So I slowly lower the engine into the bay, if something was it the way it got torched out! With the removal of a lot of tin I got it in the engine bay. In the process I managed to break the throttle position sensor, oh well. After studying the newly shaped engine bay I decided what trimming was actually necessary. I had to notch the front and rear cross member, passenger frame rail to clear the transmission, and the drivers frame rail to clear the alternator pulley and crank pulley.

I slit the firewall and pushed it back an inch to clear the intake manifold. In pushing back the firewall I had to remove the heater, to me this wasn’t a big deal I had no intention of driving in winter.

Now that I new what parts stayed and which ones went I could bring in the real 78 for the transformation.
