99 Spec turbos

[SiH]

Hey guys
Well, i\'ve finally found my car - a \'94 FD in Japan.
However, it\'s advertised as having 99 spec turbos - I understand form a bit of searching that these flow slightly better - is this correct?
My concern is about the safety of running them on stock management - Would i be best to use this as an excuse for a PFC and remap?! or would they be ok to run on the \'94 ecu? Only other engine mod as far as i can tell is a cat-back.
Any advice much appreciated

I\'d suggest the PFC (or similar ECU) anyway, if it has a free flowing exhaust with uprated turbos you could be pushing the lean envelope, should be ok, but better safe than sorry

Can i quote that to my other half when justifying the purchase
I thought as much -I guess it\'s a good excuse.
It\'ll just have to sit on my drive for a bit while i save up for the PFC and filters
Cheers muchly

Again, I\'d recommend the PFC etc anyway, however, I had 99 spec turbos on my FD (before they melted ) and they are slightly higher flowing, stronger, better built items...

enjoy.

Just to throw a spanner in, i have two sets of 99 spec turbo\'s and a set of pre 99 spec in my garage at the mo and the stock 99 turbo are virtually identical to the 93 spec Turbo but the other set is of a 99Rz and they are the bigger and Better ones. But that said the Rz Turbo\'s still don\'t have 360 bearings in so are only good upto 1 bar of Boost without Problems, now if you said you have a set of BNR\'s or something like that thats a different ball game.

ECU... Well depends on your Budget, i am personally saving up for one of the New Motec\'s but the PFC is Cheap and does the Job.

I have 99 spec twins on mine and have just remapped to 1.3bar, which is good. Also have 1.3 bar at 2200ish rpm:)

That\'s great guys, cheers for the info.
I have modest power aspirations, so they will do me just fine anyways Breathing mods and a new map will do me fine for a good while
Better get on Nengun
Cheers for the advice

When justifying purchases to the wise one always talk Fuel Economy improvements      This always goes down well as not only are you saving money you are saving Polar Bears  

"Hey Honey, these extra injectors will really improve the MPG as they are a lot more efficient"   :p

Seriously though, getting a PFC fitted and mapped will actually improve your fuel economy - so you can use this angle of attack with a clear conscience on this occasion

Unfortuantely, the effect of the \'economy argument\' is somewhat reduced as it will be a weekend car :wack: I tried it before with my last one(car!) and the response was \'well, just use it less\'
