Hello All,

Im thinking my car needs a few mods to give it a bit of a kick up the arse. It currently has a turbo back exhaust, shocks and spings and a pod...thats it!

I do know what I can get for it but I'd like some opinions on parts which are more needed over other parts. For instance, I was thinking about getting wheels, strut brace and front mount. Im not saying I have all that money now for them parts but they were going to be items I would save up for. I am now thinking there are parts that would be worth getting over them, like a PFC, coil packs and what not.

Anyone have some ideas that will get me a little power over looks, I dont need wheels right now so there is 3k saved for something else.

Hit me with what ya got :)

Depends what power you are chasing. If the car already handles fairly well and your not looking for over ~200kw get a front mount, some form of engine management/ piggy back unit (Emanage ultimate, SAFC - PFC's for RB25's are getting to the $1300+ regions these days if you can find one) and get the car tuned.

If you want more power than that your going to need to start looking at an upgraded turbo, injectors, a Z32 AFM, and clutch. A basic piggy back unit like the SAFC will not allow you to run these modifications correctly.

So maybe a PFC would be a decent option at this stage. Ive been hearing for a while now that the apexi pfc's are very hard to come buy. Is there any other brand that may be as good but maybe cheaper?

Front mount. boost control, and engine management. If you are keeping the stock turbo and cams there realy isnt any point doing much more than that to the engine as there are very minimal power gains to be made.

But if you do feel the need to do the cam gears leave the intake cam alone as the VCT gives you a lot more mid range power than an adjustable cam gear will.

Think about how far you want to take power now, so you don't muck about with gear you'll loose money on, selling later.

If your not looking to change turbo, then don't bother with a front mount that will increase throttle delay. The R34 GTT units replace the side mount one and flow to about 220-250rwkw which is already a good 20-30 over what your stock turbo will do at safe pressures.

I reckon its not worth a munched engine, due to failed stock turbo. A GCG style highflow, signal bender, maybe a adj FPR to sneak base pressure up a bit should see you 220-240

You generally cant change injectors with a bender though, so once you need more then the stockys can provide, it's AM ECU time.

Spend an hour going through http://www.skylinesaustralia.com/forums/Rb...html&st=360 and see if you can get a ride in someone's 240rwkw setup. If you want more, then start planning for a much larger turbo, ECU, fuel upgrades, clutch blah blah.

So am I able to get a GCG highflow turbo without any other mods or will that require a front mount, ecu or anything else? By the sounds of it I could get a GCG for the same price it will cost to get my FMIC supplied and fitted??

Last time I checked, GCG highflows were $1900, you can get a Garrett BB unit for cheaper than that, especially if you know somone who works for Repco (staff prices).

Probly one of my favourite mods was after having the front mount put on, I had a bit of lag, so i got my manifold cut and shut and now it faces forward which reduced piping by about 1 meter and basically got rid of any lag. But for the price of some of the purpose built manifolds of late, that would be another option. Also with the cut and shut, you need an aftermarket computer anyway cos it will lean out some cylinders, but the purpose built ones you dont.

you can get better turbos for the same money as a highflow and sell your stock turbo off if you upgrade. if your looking for a whole turbo kit you cant go past the HKS GT-RS kit $2900 from Sliding Performance (clicky for the link) and it comes with everything to bolt it onto the engine

cam's make a big difference...

On a rb26 (not really anything to go off i know) with cams pump computer, injectors + a little more boost you can get some really high figgers off the unopened bottem end. Something to consider though is how long you want to engine to last...

Stevo -

Simple effective power mods:

Step one: Front mount intercooler kit (decent size) about $600 - $1,000 depending on brand.

Step two: GCG Garret turbo kit (you can get bolt on RB25DET kits that are pretty straight forward to fit) $1900 - $2200 depending on size.

Step three: Splitfire coils + cooler spark plugs (if you put a bigger turbo on and turn the boost up you can easily blow out the spark from standard coils, helps to limit pinging aswell) - $750 - $1,000.

Step four: 550cc injectors (more boost needs more fuel) - $750 - $1,000 depending on brand.

Step five: Power FC - Best bang for your buck computer you can buy (to control it all) - $800 - $1,000.

Have your exhaust looked at, dont just assume that it will flow enough for a bigger turbo and modified engine, the one that I got with my car was almost completely blocked and had to be replaced.

Most mods will cost you a few hours labour to fit if you dont want to do it yourself - Call the boys at Trojan and talk to them about that.

With those mods you should see about 240rwkw (depending on the tune and what size turbo you go for).

You dont need an aftermarket Fuel pressure reg, or a Z32 air flow meter unless youre going for big power, otherwise the stock equipment is good for about 240 - 260rwkw...

Happy modding :turned:

P.S. I have done all of these mods to my own car, had 4 dyno tunes and almost every problem you could imagine, so feel free to ask me if you have any questions. :)

I cant help these things!!! There is just something right about it!!!!!

mmmmm next project s4/5 rx7 or RX2 coupe / 4 door with 13bbp turbo with T66 106 or just a bridge.... bloody house wish that was finished.

They's a lot more then 1K though :turned: And if 240'ish ends up being enough, then he saves $$$.

Not evry feels the need to slap a 500hp HKS unit on Race *cough* lol :)

Mick is spot on, its all simple enough to install, relatively cheap and you can have a lot of fun with that power. Or you can head the other direction and spend that sort of money on suspension,wheels and tyres and go fast round bendys instead.

Hola, como estas?

I have found a turbo I think would suit thhe power I am after. Does anyone have any experience with the garrett GT3071R or know a little about it??

Gracias

Thats using your noggin. Much better deal than the GCG highflow. P.S, I have decided to stick with the Power fc for a little while so I can at least drive it, but I have seen a few in the classifieds recently.

    • (it is a brand new ported mellings pump) I suspect the lack of pressure is due to the leak. It was *not* that low in other logs of oil pressure in the past. It wasn't that hot either, but not far off.
    • Would a Mellings oil pump be a viable option  From my time with a LS, and talking to tuners and LS specialists, the "weak" OEM oil pump is one of the first things they recommend to swap out if I was going to give the engine any high RPM I opted for a Mellings high volume, with the high pressure springs and I never had a issue with it Cost wise they are not expensive in the scheme of things 
    • Just bought a 2002 Stagea 250tRS VR-X Four AERO VQ25DET and spent the last two weekends cleaning and detailing it.. still have to do the wheels and the engine bay but the rest of it came up nice. Imported 2011 to S.A. and I'm the third owner since it was imported. I met the guy who brought it over, he went to Japan and picked out the car, bought it and ordered the wheels. He also gave me a list of stuff he did to the car with receipts. Coil overs (I have the original springs), 3" exhaust from the dump pipe back no cat, Custom dump pipe,(I have the original exhaust), Plenum spacer, 18" custom Work XSA wheels (need restoring, I've made a start..), Shift kit put through the 5 speed tiptronic auto, TV and menus/screens changed to english, Australian DTV tuner installed in rear. I've just had four new discs and new pads as well as all the fluids including the brake fluid replaced. I have all the receipts for the last 15 years and the import papers in a nice folder. Car looks great, goes like hell but fuel economy is not a thing lol.. pics next..
    • I ended up in this rut again lol, and used a shit ton of filler. One thing I can't understand is, even after using a big long block and going in long X pattern strokes, I always end up at bare metal again with no filler, and my repair started at one end of the door and now I've chased my tail to almost the other end of the door. I was thinking of hitting the panel with a hammer where it might be a high spot and making everything low then filling it, I did this on a small section on my other door by mistake and I think I fixed it lol. Is this a bad idea? The other thing is with guidecoat, whether it's the powder or spray, after I sand all the guide coat off, it doesn't reveal anything for me in terms of high spots and low spots and makes it especially hard when it's bare metal (at least in powdered form), am I doing something wrong here, or likely a high spot I keep going over and creating valleys? Lastly, stupid question but, is it possible that after sanding if I only sand over the filler area where I know to be a dent that it's impossible for me to dig into that dent? Unless there are other problems which I missed.
