Been a long 3 years building this thing in the garage as a practice build for me to learn “how to do it yourself” as I had never dealt with building a turbo set up before. I’ve threatened to sell it way too many times during this build but here she still is and every time I drive her I forget the pain she caused me trying to get parts to fit and actually work.
For a tiny 660cc motor she pulls really hard, such a fun go kart and turns plenty of heads, however the last tuner said its currently maxed at 15psi (safe tune) due to the size of turbo and throttle body in comparison to engine capacity output. Meaning to wind up more boost would require smaller turbo/throttle body set up. My goal for this project was 100hp at the front wheels.
The last dyno was a max 75hp at the front wheels which was less then the original tune and dyno of max 83.2hp but that could just be different dynos. Need to revise my set up to pull another 20hp to get to my goal of 100hp @ total vehicle mass weight of approx 690kgs. Which is a fun power to weight ratio
Next on the to do mod list is:
-an LSD set up, been looking at the NZ Compact sport site for what they have as I seen they have a 1.5 LSD for $1400. Would love to hear from anyone on here running FWD lsd and your opinions / experiences?! Not sure what my best and most reliable option is
-better grippier tyres, possibly semi slicks up front, if anyone has any recommendations?!
-New E85 tune or flex fuel
-Brake upgrade
(Want to take her down the 1/4 mile next year for a laugh and also do a track day)
