Hi,
This is my first post.
I used to own a 180rwkw Nissan 180sx, but this time I'm looking at getting a street legal mx5 that I can take to track days. The car I'm looking at is a stock 2003 Mazda mx5 and I'm wondering whether I could get an upgraded long block and put a Garret GT2871r turbo conversion on it for just under 300rwkw or whether it would be better to get an engine conversion to a Nissan sr20det, Mitsubishi evo 4G63 turbo or maybe upgrade to the Mazda mzr 2.5L 5L-VE motor and turbocharged that.
Queensland road rules limit turbo charged engine conversions to 3 times the weight of the car, so the maximum size engine I could put in the car is about 3000cc or 3L. This means I could try squeezing in an rb25det, rb30det or even a 2jzgte, but I think this would ruin the weight distribution with more weight over the front wheels and it would probably be more difficult to fit.
The car will not be my daily driver so it's OK if it's off the road for months at a time.
I'm definitely not the first person to go down this road so I'm hoping you guys have some advice for me. I'm really looking for a setup that has the same sort of response as the Garret GT2871r has on the SR20DET and that sort of power level. What would be the best option or is there other better options I haven't considered?
