Welcome mate. Feel free to PM me or call the garage direct We have 1 x 370 and 3 x 350z's in at present We also have loads of more run of the mill stuff like a RangeRover, Porsche, Ferrari etc
Sounds like Cat heatshield is resonating Could be almost anything though! You need to have your head under the bonnet and get a friend to hold the revs where the noise is loudest then hunt around. Watch your hands though... Safety first
If I was you I would go and get the remap etc at Abbey and see how you like the feel. Pointless spending all that cash unless you have to on engine swaps Also if your JDM is an 'ST' model it will have more power than stock but not sure which year they were produced. I am sure one of the JDM boys will know though
I have 2 x 370z engines in stock they are mated to spd manual box and I can supply full loom etc. The 313 engine mod is not worth doing unless your planning twin turbo then it is ideal for 500hp running stock internals
Cookie is bringing out a new unit that will be awesome. I will be testing it with him soon and it's relatively cheap and far superior to what is currently offered 800 processor / wi-fi / bluetooth etc etc
Agreed, still sounds like Banana bar
Only other thing is the suspension strut. I have over 20 in stock if one is needed but I don't think this is your issue.
