Hey, Im soon going to have my car tuned and im pretty sure i have everything!

Just wondering if ill need a Z32 air/flow meter????

Im aiming for 240rwkw's (mods are in my signature)

but basically:

RB20DET

HKS 2530

Power FC

Greddy Front mount Intercooler

AVCR

Bigger fuel pump

Rx7 injectors 460cc

full 3 inch exhaust

Is there anything else ill need????

Also how much of a benifit would a set of HKS cam gears be???

Thanks

yeah i would say with amount of airflow you'd be nearing maxing it out

im maxing out my stocker rb25 one with stock turbo at 12psi

like its only a minor 5.0volts hit but it still happens.

have a look at a set of camshafts instead of cam gear

i dont think cam gear will give a great deal whereas some big cams should increase power everywhere and give it a bit more "zest"

The AFM will be maxed out well and truly at 240rwkw.

(You can tune the maps to add more/less fuel as the rpm changes even though its maxed, but its a bit dodge)

Get the Z32 item they are only cheap and will give you more resolution and better results.

SK says the RB20/25 is good for 220rwkw

Z32 is good for about 260rwkw

Q45 is good for about 300rwkw

I reckon they run out of scope even a bit before these quoted figures, but you get the idea.

I think you will find the RX7 injectors are 550s, and will be very interesting to see if you make the power you are chasing. Best advice, dont chase the figure, just look for a good 25-30% increase in grunt, obviously depends on what your car makes now on the same dyno.

As for the AFM, ask the guys tuning your car. Some seem to be hapy enough tuning the fuelling with the AFM out of range with A/Fs verified off a wide band O2 sensor, others want you to have an AFM

Roy, probably NA RX-7 injectors, which are I do belive 460ish. Id say they would go better than the 550s for driveablity also.

Id just upgrade it tho anyway. Why do things by halfs? Also if the engine goes, then thats another thing your going to need to upgrade then.

Id also guess the bigger size would let a bit more air thru, not a lot but hey, every little bit!

im not really too fussed with kw reading anyway, I just put that in as a guide for you guys!

As long as its making over 200 at the wheels ill be happy :rofl:!!!

You say that now but after a couple of weeks driving around with 200atw you'll want more :(

The good thing is with the items listed you can have a bit more power fairly easily.

im sure people can get on here and say me mate dave got 260rwkw with the stock rb20 afm, but seriously uve set the car up nicely so why not sell the stocky for $100 or something get a z32 for $220 or something, get it tuned definately have no worries

the z32 will definately be better for the tune for that power than the stocky - better resolution its not really that the rb20 one is restrictive

Or you could do this and never worry about how much air flow you need....

Im sure you are a wanker.... I said nothing about 260rwkw and neither did hawker05

Why upgrade something when the stock one will be enough for his target power, perhaps in the future when he is chasing more power it would be a good upgrade then. When the limits have been found and not simply spend another $400

Im sure wankers can get on here and say upgrade everything mate when they havent noticed what other people have put out with the stock one.

Just because u can understand how an MAF works and type the word resolution doesnt mean he needs it a z32

Do u know for a fact that the stock airflow meter will max out before the turbo? or did your mate dave tell you?

There, i saw your 1 cent and raised you 4. See if you can make 5 cents worth next time

No your right it was pretty rude the way i put it however it did seem that your post implying that my mate "dave" had told me some magical figures. I also think that everyones mate dave gets on here and creates "skyline myths" such as "Rb20 standard MAF wont do over 200rwkw". As a result dave is going around telling everyman and his dog to toss his MAF just for fun.

I do appreciate that you were trying to help this guy but i think unless you have personally run out of resolution (or whatever the case may be) that comments are best left to ones self. Posts with information based on own(or atleast someone else from the board) experiences are far more useful for whoever they are meant for.

Sorry again inissane

      This looks great! Awesome to have the 5 speed with an LSD in this. The Recaro's look like SR2's or SR3's. It's a shame they've been retrimmed as they would have looked sweet in their original colours. I think I'd want my agent to be a little more up front and informative too. I've never imported but I reckon it would make me a little nervous, so the more info the better.

      Thanks for doing that Duncan! Makes you a good person in my books. We don't get kangaroos or wombats here. But we have bats and it's similar. AFAIK it's often the mums with a baby attached that get hit because they drop lower when starting from a tree. If you hit an animal, check on it. https://www.ifaw.org/au/resources/wildlife-rescue-app An app to get the closest wildlife rescue contact.

      My dream is also to have a proper hoist, but I don't think it will ever happen. My quickjack is probably as close as I'll ever get, it really is very good though.

      Yeah we keep on in the dailies, it is pretty poor how many animals get hit and the driver leaves without checking....have saved a couple of little ones over the years. Bit of a gruesome job though, pouches generally need to be cut open because they are so tight and often the joey doesn't realise mum is gone so they are still locked onto the teat. I checked the modules in front of the DS wheel where an oil cooler should go.... There is the radar unit - that can go for race use) One of the 2 HX water pumps, the silver cylinder. That needs to be kept but might be able to be relocated But the bad news, the big computer mounted vertically in front of the wheel (blocking any potential air exit) is the electric steering computer. That is required until/unless i do a hydraulic steering conversion, and in CAD based modern car design it is not like I can just pop a big unit like that somewhere else (plus the loom would be too short anywhere else too). So, the passenger side is OK to clear out (just use a smaller washer reservoir, potentially elsewhere), but the DS no beuno

      Well, all the best with the new camry It was interesting to hear about the UK process, it is generally a lot more streamlined here with a shipping agent looking after all the import side (noting the exact final price can still be a surprise.....) and I've used a few different brokers on the japan (or US) side, and never had any trouble with any of them....luck of the draw I guess. You mentioned you didn't get the auction sheet (understandable since you bought it from a dealer, not auction), but I always try and get hold of that because they are pretty thorough. I've imported 2x R grade vehicles over the years and both were fine, repairs in Japan are pretty thorough compared to here in Oz.
