Hi guys,

I am in need of some sound advice from those that have already gone down the upgrade road...

I have a r33 1997 v spec gtr with;

power fc

Profec B elect boost

Custom hi flow cat and exhaust

Pods

I have just brought:

HKS Adjustable cam gears

Garrett -5 (n1 style)turbos

Trust front pipe

I need to know if it is vital to purchase injectors, fuel pump, fuel reg? Anything else i forgot? From what I can gather dumps will be ok at this setup and possibly pumps etc...

The car will get full install from powerplay - sydney, and then dyno tuned. Looking for more responsive car good power.

Any help appreciated.

Cheers

definitely get injectors, fuel pump and reg not THAT necessary as long as its a safe tune. But the question is how much power do you want?

And if i got adjustable cam gears i would definitely want to do a fuel pump and reg to get the most out of the car.

Thanks, Any particular type of injectors and pump? I am being told only nismo for both?

talk to your tuner before you go buying anything mate , if theyr'e any good they will be able to tell you what will be necessary :P . note: i've noticed that alot of people don't stop and think about the smaller servicable items on this site (i.e oxy sensor , fuel filter, temp sensor etc) , before you go trying to upgrade your engine have a think about the last time these were changed and whether it might be a good time to do so :P

640 or are they 660 cc nismos would do the job for stock bottom end safe power, fuel pimp definately, those turbos are good for more than you will want to safely throw down the stock motors throat but afms (if u did not go djet) would limit gains I think to 300rwkw,so may want to consider z32 or equiv.

I would also consider catch can and cam cover baffles.

    • I've owned a few scooters over the years, a Vespa PX oil burner was my first scooter, followed by a few others, including a little 50cc BeeWee that I used as a barracks bike, and I've had a blast on all of them, they really are the cheapest for of city/suburb transport around The only issue with scooters in Australia is lots of people look down on them due to their size,  maybe they need a big bike to make up for something else where they are lacking, unlike Europe and Asia where every man an their dog owns one, and now that filtering is legal in NSW, local traffic is never a issue Not to say I haven't owned my share of big cc bikes over the years, but they were for more blasting through the hills or Hwy riding where it needed to sit on Hwy speeds Safety wise, I ride like everyone is always trying to kill me, everyone is running a red, or running stop/give way signs, or generally asleep at the wheel, which most people are duringtheir commute, I also ride really safe, and give myself, and everyone else enough room in case I need to pull some hasty evasive actions, I've done a few rider training days over the years, which has come in handy on more than a few occasions  As for mods, there's nothing really, and yes your right about aftermarket exhaust, all you get is loud and obnoxious noises from them, like every 250-300 cc you hear with a aftermarket muffler, in saying this I did put a rear muffler from a 125 Aprilla on one of my old 125 scooters, it was horrendous and no amount of full face helmet and ear plugs would dampen that noise As for coming from the Harley, and what a overpriced POS that was, I no longer do big rides as my poor old busted joints ache after about 1/2 an hour of riding, long cruises are so much more enjoyable now in a car, so a big bike would be pointless   
    • Oh wow, it's easy to forget how cheap these can be. Probably the cheapest way to travel. Though people in cars here tend to be morons and I would not feel very safe. Were scooters ever big in Australia? It used to be the thing growing up in Europe ~20 years ago. 50/70/125ccm Peugeot or Yamaha and some others. Utterly obnoxious Polini race exhausts. Kick stands that slant as much as possible. So loud. So much noise for really not moving very fast at all. But it felt cool at the time. Not sure where I'm going with this, but there is an aftermarket for mopeds! Though I'd have pictured you more for a Goldwing kind of guy after growing out of the Harley.
    • You need to know I am sorry for this.  
    • As the MX5 isn't apparently "manly" enough, and I need something for runs to the local shops, and also take to my part time job at the salon, basically I can keep the MX5 away from car parks and stuff......like "flying lockers", I was wondering what I could buy to fix this issue LOL, I pick up a new Yamaha 125 Delight this arvo from Trooper Lu, basically a R1 that you can fit a slab of beer on between your feet, also, it was $29400 cheaper than a R1, so actually it's 2 x better than a R1    
    • Nah. H2S. H2S is "rotten egg gas", which is what is associated with no cat. SO2 is equally nasty, and if you've ever smelt it you'll know all about it. More of a choking, acid in the back of the throat sort of thing. But you can only smell it in a narrow range up to about 1ppm. Above that, it irritates your mucous membranes, but you don't smell it.
