Hey guys I have an r33 it currently has little or no mods..

Pod filter, FMIC, Cat back exhaust and Boost Controller (running 9psi)

anyways on the dyno at dyno dynamics in bayswater it pulled 181.7kw.

Im looking to get around 200kw out of it without going all out on mods.. obviously next I need to get a full exhaust..

What else???

Upgrade your dump/front pipe and cat. Then the easiest way would be to turn the boost up a couple of PSI. Maybe up to 11. I'd imagine you'd be pretty close to 200 then and should only cost ya about $500ish. I'd recommend the JJR split dump/front pipe and JJR hi flow cat. Very good price, check out the JustJap sponsor area of the site.

Can top it off with some aftermarket engine management. Could get something like a SAFC II or Neo and get it tuned up. That'd be the cheapest way.

thanks guys I heard the power effort wasnt too bad for those mods my mate went also he has a similar setup to me except no front mount and boost controller but a full blitz exhaust and split dump and he pulled 175... i know that in shootout mode the power figure is a lil higher that the realistic output but im still rather happy.

im also looking into the new unichip which is soon to be released the one that can be used as a full engine management system or piggy-back with the stock comp.. dynomotive quoted me around 1500 fully installed for that.. although it wont be released for a few months.

not sure of the comparison between that and something like the power fc..

you should up the boost to 12psi. 12psi will be ok on a stock ecu....do this on a dyno though to double check its not pinging etc...200rwkw should be reachable with 12psi :thumbsup:

after this if you want to run more boost, either get your ecu remapped or another standalone ecu and probably tune anywhere to 14-16psi..obviously you would need any supporting mods your car would need to run that amount of boost etc...

pod, full xhaust (dumps, hiflow car, mufflers), udp, ecu, and boosted accordingly should give you some great results...

might wanna add a disclaimer to your advice chad before your advice blows someones turbo/engine up :thumbsup:

go past 10psi and the stock ecu will probably go into rich and retard mode making your car lose power, not gain it. go past 12psi on the stock turbo and you'll probably fry it pretty quickly :P

past 12psi on your stock turbo will fry it??? woahhh not much boost ...wat size turbo is the stock skyline turbo?

mmm i was just at a shop with a tuner talking to another skyline owner giving him tips for more power. sorry if this is not correct

they're ceramic (series 1) and nylon (series 2)...they're not steel wheeled....12psi is the advised max for em and anything more is asking for trouble. some people's last ages on 12psi..some dont last at all. I personally know 2 guys that ran 12 for quite a while before they fried them, and 1 guy that ran 12 for half a dyno run before it let go...luck of the draw

the stock ecu doesn't like boost, so if you go past 10psi its likely to go into rich and retard which will make it slower than stock anyway

also past 12psi generally wont make any more power than it does on 12psi anyway...just create more problems

as for the workshop you were at....doesn't sound like he has any idea what he's talking about :thumbsup:

ahh yes thats the reason why they dont behave well when boost is upped because they are ceramic.

yup when boost is upped if detonation occurs ecu is thrown into safe mode (richer fuel map, timing retard etc)

12psi aint much at all, these turbos loose effieciency after 12psi...ahhh this is why i see so many skylines with huge turbo upgrades...

i wonder why nissan put a ceramic turbo in it...are they all ceramic even up to the r34? or did nissan change this?

good info :thumbsup:

Dont pay 1500 for a unichip get a power fc its a full replacement ecu and a lot better I can tell u that much and its cheaper.

good luck finding a SECOND HAND pfc for the price new 1's went for back in the day.

they sell for anywhere from $1-2k second hand these days :D

yeah i know guys its all just a number just like the skyline is just a car but we dont say that all now do we :thumbsup:

Wayne let me know when your free the exhaust is locked away in the back shed I can bring it any time :woot:

As for the unichip power fc debate.. as I was saying at the end of this year unichip are bringing out a new module onto the market can be used as both a piggy back and full stand alone unit.. so for 1500-2000 inc tuning I reckon it might work out a lil cheaper than then power fc..

      V37 Radiator removal

      By Duncan · Posted

      So, this shouldn't be such a mission, but there were a few tricks so I thought I'd post up a DIY for it. This was on a Q50 Red Sport but I doubt any other V37 model is very different (maybe just less steps for the intake heat exchanger hoses) I pulled the radiator out to flush it because the car was running hot at the track, but obviously the same steps apply for changing a radiator for any reason including an upgrade. If you are removing the radiator, you of course need to drain and refill, so have 5+ litres of blue coolant ready. You don't need to drain the intake heat exchanger to remove the radiator but depending on your plans you may need a couple of litres for that as well. You will also need something to deal with the auto transmission lines, I used 2x 8mm rubber caps on the radiator side, and a short length of 8mm pipe on the car side.....unless you can block these lines quickly you will loose AT fluid and it may be enough to hurt the transmission if you don't refill it. Other than that....lets go... "First, jack up your car". Yes really, and put it safely on stands. If you are not confident doing that you need to give this job to a mechanic

      If the forester is anything like our old 2007 GTB Liberty, I could near on run ling Long's and "rate them", as no matter what, it just hung to the road, even when abusing it in a hard launch in the wet, or throwing it at corners.

      Boost cut after swap(RB25DET NEO) R34

      By GTSBoy · Posted

      Don't even try to run it on the stock ECU if you're going to have the boost controller bring boost above ~10 psi. I've already told you that. If you use the Nistune ECU, you will need to CAREFULLY read the available documentation for Neo tuning, and read some threads on the Nistune forums, to discover the various things you have to do to prevent the ECU from going bananas when the boost is too high. The is a table associated with th boost sensor that must be modified to prevent it from shitting the bed. This is just one of the things that you will need to do to the tune in Nistune, because the Neo turbo ECU will be expecting to see a number of things (such as the TCS) that are not there, and you have to block the DTCs on those. It is totally not surprising to me that you are having the problems that you are, but the solutions to these problems have been known for >15 years. So just get it done.
