Hi guys
As some of you will know i\'ve had my FD for nearly 18 months now, i\'m 24 and love booting her up (but i am very sensible about it) so touch wood not a single accident yet
As of that, i think its now about time to try getting a bit more from her,
Its a completly standard 1300cc twin turbo (Bar an induction kit)
I have no idea where to start and was wondering if some of the more experienced guys could give me som advice
Thanks alot guys
Mike
Depends how much power you are after?
That will help you decide if you should go single or stay on twins
your first step really should be a new ECU. at the very least one of the \'pre-tuned\' ones like RE-A or Knightsports, that way you won\'t run the risk of detonation and a new engine.
also get some gauges if you don\'t have them already (water, oil, boost...)
If you get an Apexi PFC with the commander then you\'ll have an ECU that can be remapped as and when you up grade bits. Plus the commander will give you the extra gauges as well.
Seeing as you\'ve got the induction already then look at the exhaust. Ditch the CAT and get a better down pipe and free flowing exhaust. Lose the air pump at the same time (blanking off the holes left). This should see you getting some easy extra horses and response from the engine :D

I have a knightsports Ecu that came off my FD if you want it

Ok mate, how much would you want for that and what kind of bhp would i get from it?

ok i think i\'d be looking for about 400bhp max tbh
fly or wheel.

sorry... whats the difference

ok how much am i looking to spend on a Apexi PFC with the commander and remapping?
Quote from: mikemike180;607311sorry... whats the difference
about 18 %
like already said your first step is to get aftermarket ecu Apexi/motec etc.
probably new fuel rail/injectors, fuel pump/fpr and a remap should get you somewhere near.
also with more power your going tto need better cooling i.e uprated intercooler and rad.
if i were you i would stay away from any of the pre tuned ones as 1. you cant confirm what mods they have been mapped for and 2....they have probably been mapped for japanese fuel which is 100 RON...!
just not worth it if you engine is sweet!!!
Thats not 100% true, Knightsports will give you a list of what mods the ecu was modded for etc if you post a message up on their forum with its serial number :driving
But yes the 100+ ron and not knowing what the ecu was mapped for and how conservative it was can be a BIG issue. :eek:

I used to run a MINES STAGE 1 ECU on my R32 GTR with AVCR. Mapped for Japanese fuel as well but runs pretty sweet with V-POWER.
However RB26 is one tough engine and I won\'t try the same thing on a Rotary.
Quote from: mikemike180;607311sorry... whats the difference
400 fly near enough 340 at the wheels

Is it really worth it for the stock twin though? I am kind of on the same boat here. Intake and back box. Planning to get down pipe and mid pipe, map it and call it a day.
With injectors, fuel pump, intercooler and everything why not go all the way and get big single?
all depends what power you want really. if you want to stay on stock twins then probably not. although better cooling is always a good option no matter what you intend to do
Apexi ecu
Full exhaust system from turbo(s) back (need to go single to see safe 400bhp!)
injectors
Intercooler
Fuel pressure reg
uprated fuel pump
going with stock twins you could see 350bhp, but any more than that I think you will be replacing turbos on a regular basis, so it you want more, then a single turbo is the way forward!!
Then a remap for the ECU!!

I saw 380hp at the flywheel (320 at the hubs) with:
Apexi PFC,
Tripple Core Front mount,
1300cc secondaries (with better pump),
Twin spark,
80mm Downpipe,
80mm mid pipe
Ziegen Backbox.
Electric Waterpump
C-West Front Bumper (Improves air intake).
Stronger Clutch.
This was with the Turbos tuned at 0.95bar. Only really swapped to the single when I started having boost issues that were caused by vac line issues.
Its all about cooling. I\'m still running a stock rad, although it has had a brazed top cap fitted before I bought it and its still doing ok. On the single I\'m also running water injection and much more fueling. Its not a big turbo though !

OK mate thanks,
So how much do you think that would end up costing to change it to a single turbo?
that is when the money comes in, as good turbos are not cheep, especialy if you buy new!! then you have to get a wastegate, exhaust manifold, down pipe, & the cheepest bit: air filter! then you have to custom make the pipes to the IC. so you would probably be looking a few grand :(
Jono
if you want more power you are gonna have to change the injectors, you cant really turn the boost up much without maxing out the stock injectors.
Like others have said Apexi Power FC is a must and one of the best mods you can do
the cost of going single from stock is probably closer to £5000.
i gotta agree you will almost certainly have to upgrade the fueling.
yes when you add it all up, going for a decent single setup is gonna cost quite a bit, i built mine up over time so everything was ready for it then when i went single bought one and just bolted it on, job done :)

Ok mate, do you know any web sites i can pick one up?
probaby best to give one of the tuners a ring they might have one in stock if your lucky
Ok guys
I think at the minute i should stick with the twin turbo\'s and just try pushing as much as i can, i\'m still not sure exactly what i\'m needing in an apexi pfc, are they pretty standard?
The PFC will come with a base map for your car, however it will be best to get it mapped pretty quickly, as it runs pretty rich on the base map.
You can pick em up from Ebay/Tuners etc..
These guys have some new and used one\'s in stock most of the time:

That\'s all that most people do. The majority of the mods done to build a single are done to build a better twin. The apexi, fueling & cooling are the first bits !

they plug straight into the standard ecu loom (underneath the passenger footwell trim). the only reason i\'ve not bought one is because i\'m a bit short of cash!
it\'s a lot easier to lean out a rotary with basic mods than a piston engine and the consequences are a lot more serious. your average turbo four-pot can cope with detonation to a certain degree, on a rotary you\'re going to do damage. the apexi is the best way to adjust your air/fuel mix to stop this.
