First mod I would have done is drop and replace every fluid in your car, sparkers and leads, and airfilter.... Yeah I know its not a mod mod, but... Your car will be alot smoother and you will have the peace of mind knowing when it was all actually done... But considering you have had it for 8 months ou may have already changed all that...
Umm.... Considering how your wallet is going after the exhuast, because this should always be your first mod because you bought a V8 you want it to sound like one too
An OTR is always a great thing to next.. Custom tune if you like... If you still got $ go cam an tune.. Or if you got the $ from the start most good workshops do a exhuast and cam upgrade in one hit.. Which is a rather awesome first mod..
Considering your from rotary background, you may or may not be liking the big V8, I know a few mates who have done the same, an say they arent a huge fan of it till it gets past like 80kmph, coz big V8s just keep pulling into what seems like infinity.. Possibly a set of diff gears might make you happy...??
They will ofcourse be cheaper then a cam' upgrade however will also effect your fuel a little as ofcourse your cruising RPM will be higher..
If its an auto box ur running a rather good set up is either 3.7 (if you plan on doing hwy driving this isnt really that bad) and 3.9 if you don't really give a hoot about cruise RPM on hwy.
If manual, 3.9's is good then 4.11's if your thinkin of dedicating it to the strip a few times...
But thats just a thought.. It will accelerate a LOT more off the line with a change in diff gears which is what most ppl from rotary and importers like..
Anyway, thats just my two bobs... Sorry if you hate it.. Some ppl wont like it.. But ohwell..
