[Fot] TR4 5 speed conversion

[Barr, Scott]

Right on time, it's the spring transmission debate!  :-)

For my street/track days GT6 (Col. Mustard), I used a Toyota gearbox conversion from Conversion Components in New Zealand.  There was a little weirdness with the badly sized slave cylinder, but other than that I was very happy with the kit.  I have no idea whether he's still in business, as this was a pretty long time ago now.

Like you, I got damned tired of changing the trans.  I got it down to where I could have the old one out and the new one in in under two hours.  Got tired of that.

FOT members, I am at my breaking point with transmissions for my racing TR4, six rebuilds in past 4 years, the last 4 professionally. I try to keep my car as original as possible, but this is costing too much, and I am missing too much track time at races.

For RACING only, can anyone give me pros and cons of the conversion. Looking at the Vitesse Mazda conversion.

I know it is not "legal for vintage" but I still want to race and within my budget!!  (Don't know what my budget is)



Thanks, Mike
