Hello Dave I was racing at NRS @ NNRC the other week when you where there. I dont think you need to spend £300 on a motor to be competitive and you can trash a £300 motor just as quick as £70 one if you dont know what you're doing.
I'd forget pull start and get a starter box for 1. It is indeed .21 you're looking at the Sirio 3 port motor is a little cracker for about £120 or an RB H9 (5 port) is also a belter for about £175.
I've run RB's for a while S3's WS7's S7's and now just got a K9 which seems very good but isnt Novarossi made like the rest of their line so will have to see how well it lasts. Perfomance wise its not as smooth as a C6 nor as good on fuel so far (but we'll see as I tune the performance). I run an RB pipe the 2045 which is the best alround performer / mpg, but RB pipes are very expensive now for what they are imo. Quite a few people running Jammin JP4 pipes with RB's you also need to consider if the pipe will fit the car right, my Mugen MBX6 needs a tighter bend header or it wont fit in the car.
Dont overlook the clutch either as thats also vital for good performance. RB's like a late engagement (1.1mm springs) otherwise they struggle off the bottom killing performance.
Motors I'd look at if I was in the market from cheap to dear
Picco P3 Basic £75
Sirio CL3B £120
Novarossi NR21R £125
RB H9 £175
RB S9 £200
Reedy 121VR £250
Novarossi Plus 4 £250
RB WS9 £290
RB B9 £340
PS Just because you pay £300 for a motor doesnt mean you cant turn it to scrap in 5mins with the wrong tune
