    Blimey. That’s been a trip and it’s still not over…. But things are closer. 
So we’ve got the g13b DOHC installed. Custom exhaust and a link atom X ECU.
Thats all pretty much sorted and wired in (in the engine bay). 
We struggled to get the link ECU to drive the DOHC injectors as they are old school low impedance peak abs hold. Now sorted with a set from a v8 Toyota… well half of them… we’ve got swift mk3 wasted spark, a skyline temp sensor… and custom trigger wheels in the dizzy and on the lower crank. 

I’ve only rumbled home short shifting from the rolling road so far. ( road tyres on the rear and the 30’ muds up front don’t inspire confidence) 
It’s smooth torquey and wails luck a banshee when you open in up. Can’t wait to get the dash in an have a proper play!

Very good figures on the Dyno there, i would be happy if it was mine :)
I like the dizzy and coil setup here, hoping and thinking it will also be trouble free. Is there an oil drain back to the block in the dizzy housing on these if I remember correctly? I know some easily leak and other get too little lube for the angled gears or the cam shaft dizzy coupler. (Or is that only on the SOHC..)

Would jimny/baleno ignition and injectors be a way to go if they were available to you maybe? still G13B stuff and would mostly fit perhaps.

As there most likely is nothing Grand about the Touring there is no need to call it a GT for the Insurance :)

The injectors selected were on two points. Physical fit.. but also the availability of the full specification including the dead time to get a really crisp throttle response. 
They are also a bit bigger… this combines with a three bar MAP sensor and a spare pulley on the crank is provision for a supercharger should further ponies become necessary….
