Doug,

Cheaper option is to bypass the turbo all together wit the coolent pipes !! Much cheaper & not needed if you warm up & cool the motor off properly !! They was only there to warm the turbo up anyways !!

I never run coolent through my T35 for 3 years, never had a problem !!

Know the feelin tho, when I first built mine I drove it 3 times & the engine let go !! After 2 months building it from scratch, I wasn't impressed to say the least, then this engine came up from Phil @ perfect timing !!

Keep wit it, where bouts in London are ya ?? If you need any help jus give us a shout !! Saves you gettin stressed wit it & gets it back on the road !!

Is it 2 or 4wd ??
