Few things really. I'm trying to keep the power or more torque relatively low, I'm still on a 5 speed and 215mm clutch which I don't want to lunch every 5 min lol. I'm running a return fuel system so have more scope from the stock injectors than the meg does, plus the scaling on the stock ecu will need major work to work with 630cc injectors., originally it has injectors big enough for 125bhp. Then as silly as it sounds I don't think id need more power for a while (mad I know lol) 630s and a 15t would see me at 300bhp+ (and id be scared to use it, bottom end worries) then the cost too
As a side/future project for more power and reliability I may swap out to the meg ecu and fit an ndo box but were are then into a lot more work and cost. Would probably need custom shafts for that one but would ultimately require a big outlay in comparison to this. Id also want rods and pistons to make use of the increased strength of the box, maybe a 197 head too.
This project has so far served me well, has kept me mentally busy whilst stuck home and has been built full on PMT style for basically peanuts (see above for costings) Id like to get an use it this year abit then decide what to do next.
