FINALLY THANKYOU MAN FOR A RESPONSE.

im going after 600hp. and if i get more. its a bonus.

DONT worry about internals (springs, pistons, sleeves, rods, solid lifters,crank, valve stems/guides./fuel supply (squirters, pump/s), electrics etc.

im just wondering what size turbo would get me there that comes on boost below 4000rpm if possible.

if possible, a snail that gives me breathing room to go further if i ever want to..

but for now 600-700hp snail is what im after.

i was thinking a US-spec super t70

you have a few opinions

HKS T51R SPL

HKS T51R KAI

HKS T04Z

Blitz K5 or K6

Trust T88, T78, td06

etc etc....

i would look at a hks or garrett T04Z, size it up to how much power you want so you can select the correct rear housing size, not sure if you will be full boost under 4000rpm :happy: check out this topic : http://www.skylinesaustralia.com/forums/Rb...yno-t55845.html

its got alot of information of different types of turbos on rb25, also cams will affect lag etc...

how come ive heard of skylines running 12 psi with only a cooler and exhaust?

The stock turbo is fully capable of making 12 psi, infact likely much more then that [ ive accidently hit over 15 on mine :) ] . However the life of the turbo is much reduced when running levels of boost higher then it was ever designed for.

IE you can do it, you prob just wont be able to do it for very long.

without some form of modification to the standard solenoid or some other form of boost controler, im not sure how just an exhaust and cooler would cause 12 psi?

taking the stock ceramic/nylon wheeled turbo past 10-12pound is inefficient.

the ceramic wheel was built for response not power.

it will simply not be efficient at these levels.

it doesnt have the mass to sustain the boost levels past 12pound

Its because you're running less backpressure and hence giving you more power ... the more psi you boost it up to means more turbo lag... I wouldn't say you go faster - more so less lag... if that makes sense.

arent we in the forced induction section? or is this the v8 section??

ahaha so stupid...

WOW my topic is still open!!! WOOT WOOOOOO!

Anyway, I purchased myself a Power FC, brand new one from ebay for $1,540 with 1 year warranty and invoice, not bad considering second hand ones still sell on ebay for $1,300!

I haven't gottent around to installing it yet, however, I am sure it'll fix my problems!

I also got an a brand new Apexi NEO that I am selling if anyone is interested ($320)

I want to upgrade my fuel pump, does anyone have any suggestions as to what I can get, and how much itll cost me including installation, fiurthermore, will I see an Increse in power from it?

CHeers ladz

don't know anything about safc but if it works for GTT R34...ill take it for $250 :D

Dude, they are selling on ebay for $400 without postage cost.

ANd yes it will work for you R34. In addition, I also got a genuine apexi stand for it which I will throw in for free.

here ya go mate... depending on your power needs the bosche 040 is perfect for your needs and can sustain 400hp.... from memory it is about 200-300 bucks...

it has a filter in it...so its a direct replacement. just put it in the harness...then slide it in.

Yer bosch 040 are a good little pump.. although you could get the new walbro pump that is still intank but flows as much as an external bosch 044.. about 600hp from memory... haha although this would be overkill for you, so 040 IMO

I would reccomend the bosch over the walbro, i had the walbro and it shit itself in less than a year, also had a mate that had one and it died too.

    • That idea has crossed my mind, I do a 5km walk everyday, this does take me past some bushland......I think you may be onto something 😉  That, plus 1 rock on every bin night might do the trick, it may take a year, but it could save me a couple of grand The only issue is the big 'Boonies", I have a few that weigh around 30-40kg, maybe they should be the first to go into the raised garden bed,  and then let the next owner deal with them....my daughter gets the joint when I kick the bucket, mums the word mate......LOL Noice......
    • Wow. Did you call the car a Nissan Skyline?
    • You're retired Mark, on bin night, go for a walk, kind of like you're doing the beep test. Put one rock in the first neighbours, come back, get another rock, go to the second neighbours, repeat over many weeks. All rocks eventually gone...
    • No chop chop of anything mate, it is what it is, plus, I don't want any air that isn't either going through the cooling stack or intake getting into the engine compartment increasing under bonnet pressure  Yeah, the Mazda Speed aftermarket intake above is less than ideal for multiple reasons, the requirement to remove the bumper every time you need to service the filter, and also smaller in diameter than the NC1 OEM one Weirdly, Mazda Speed is part of the Mazda motorsport division, "form over function" and $$$$$ for Mazda from unsuspecting punters I suspect  After some googling about them it seems they added no power, but do increase some induction noise Meh In other news, the electricians have been busy today at the house, and are back tomorrow finishing up all the security stuff and exterior lighting, they also added some lighting on the garage ceiling, which will come in handy when working in the garage when it's not freezing out there My Birdies raised garden bed also arrived today as well, which I'll put together and place tomorrow, it's a big tall Bessie, 74cm high, 92cm wide and 214cm long, this will come in handy as I am starting to get "stockpiles" of good soils from doing landscaping, some of the clean rock, namely the river stone, will go into the bottom of the bed for drainage, as well as the old Apricot tree that was out the back,  and when it's full, I'll grab another one, I will be growing enough veggies to keep me both busy as well as supplementing the shopping list I'm also awaiting another quote for a new Colourbond front fence, as the "1980 style cemented in rock edging" that was there and "fashionable at the time" looked arse, and my god, the amount of cement used to fix the rock was insane, it took 1.5 days for me to break out 12 meters of the stuff by hand, trim the bushes back to the fence line and dump it out the back of the joint to deal with at a later date,I will soon need a skip bin to tip it all Unfortunately they did alot of the cemented in rock around the joint, which I hate, so a few pallets of retaining wall blocks for around the front and back where the cemented in rock is will be required to bring it up to a standard, and look, that I will be happy with 12 meters worth of rock and cement Finished smashing the fence line and ready for a fence to be installed, yes, the lawns need some TLC and thickness, the previous owner trimmed the grass to the roots 😢, the TLC I can provide, and nature over time will do the rest And there's probably about another 40 meters worth of this landscaping abomination left to do around the front and back gardens, I'm guessing maybe 3 or 4 tons worth, tip fees for this will be a killer Meh, all in all I'm having fun and keeping busy, plus, it's good PT
