You've done great work on this project, it looks great, theres no way it looked that good from the factory.
Time to get driving her now
Ian my advice would be keep it original work on the engine you have a word with mr f [Mike Feeney at mjp he will tell you what you need and possible supply only my thought,as their are a lot of hybrids about don't really know if you would be devaluing your car. If you are looking for something to race and keep then fine.
GOOD LUCK
I'm still undecided on what to do at this moment, I'll worry about that once I have the suspension, brakes, diff setup and paintwork sorted.
Whatever I do it will be done with my personal enjoyment the main consideration, I'm not worried about loosing or adding value to my car, I plan to keep it for a very long time. If I decide a tuned L series would be better for my needs than I'll go for that but If I decide that I want slightly more power then I'll probably go RB26.
