I have changed Tunners because with the new Tunner i be able to do some work on my car if i wish plus i can bring some parts in intercooler etc but must important they are always thinking about my crazy ideas and are willing to test them plus we have move our camp to that shop and they are taking care of my buddies
500HP Honda and my Buddies 600+ M3 BMW,latest proyect from the camp in mind is to install a M5 Engine in a 88 M3 will see.
Back to you qs.
1)Based on my research the twin plug will be good for 600+hp so very hard for me to justify the expense before i do that i go with a Electronic Mang System and after this in the longgggggg run i may turn her into a 3.4 twin turbo if my wife dont kill me!
2)Rods i was going with them but unless that we use titanium for the weight the stock will hold the secret is the rod bolts
3) Cylinder Heads as you know they are pretty big and i see not a need to open them anymore but if i had the $ i will port them to match the intake manifold which i could extrude hone but again we are only looking at 550hp if i was going for 800+ for sure,but you have to stop somewhere,I have to tell you that theres many combinations out there i just feel this is the one that will work for me, hope this helps.
Regards Juan
