Well you have most of the major stuff done already. First thing I would suggest is get a fuel pump. Your stocker wont give much more. A partition and CAI are cheap and good mods if you are using a pod. you can quite easily make these yourself. A cold air feed is pretty important with a partition though, otherwise you could be robbing yourself of power. As suggested before, get a 3" system all the way through. Your clutch will probably be close to its last legs - gotta get the power to the ground. If you go single plate I would suggest having a look at a lightened flywheel. Adj exh cam wheel are a good addition too, seen these from around $80 second hand. If you are just using a bleed for boost control, try an EBC - much better, boost harder sooner. Get it all tuned and buy some decent tyre with grip, you will need them.

bigcarl, if you are running a highflow, it should easily support over 220rwkw. The stock turbo can make it there, just has trouble remianing in 1 peice because of the ceramic turbine wheel. What are your final hp goals? With cats, some 'high flow' cats are not much better than the stock one. Perhaps someone else can help you out a bit more, as I have a special highflow for exactly that reason. An adj exhaust cam gear would help mid range and top end, as well as help bring the turbo on boost a bit quicker. As for worthwhile gains, it depends on how you quantify a worthwhile gain. If you havent already, try fitting a lightened flywheels. Second hand jap ones that weigh around the 4.5kg mark can be had for $350. wont really improve top end, but will give you MUCH better responsiveness. what mods do you actually have? alot easier to make suggestions if that is know first. A couple of ideas to think about anyways. It is alot easier to make suggestions if you tell us what mods you have and what power you are chasing and what application it is for street, track etc.

but you CAN drink a sh1t load of piss.

If you know what a turbo performs like, because thousands of people have used them with great success, why need a compressor map? I would also ask how many people read a compressor map before selecting a turbo? Alot of people ask what experiences others have had when making their mind up. If you know it works why do you need it? Getting a turbo selection right requires alot of research. Even with all that research sometimes it goes wrong. There are guys on here that have bought highflows only to find that they surge and have to take them back to get sorted, repeatedly. Now if a turbo shop can get it wrong, how hard would it be of the average guy on the street. It makes sense to go with a turbo that is well matched to a car. If all you had to do was read a compressor map, then this thread would be totally invalid and superfluous. Its not. Just as a little example in retort to your list of the many things that go wrong buying a second hand turbo HKS 2530, reconditioned, polished compressor housing (for that rice effect) with braided lines $2200, any test welcomed before purchase AND 10% discount for SAU members - this is a turbo that was sold at D1 garage. Fitted up without problems, worked beautifully as they do. There are horror stories, but with a bit of care, it can be a success story. They do come up in great condition at ALOT less than GCG charge for a recon. king_kw13 I have a HKS 3037S 56T. Troubles fitting it? none.

Hmmm, c)ck flavoured soup with crap.

Thats just a little childish isnt it?

And one for the ladies:D

Time to ressurect the wasteland, hippy isnt the only one that can find wierd food photos

A second hand parts dealer will sell a stock RB25 turbo for around $600 in decent condition. If the turbo is in excellent condition it would be easily worth around that. GCG give you around $450 trade in on your turbo when doing a high flow. Hicks, what turbs are you getting?

Other side to the battery, there is a metal plate sort of khaki colour. Underneath is a big plastic screw on lid, has 3 fuel lines (one supply, with yellow band - one return and one for emissions?). If you unscrew it, you will find the fuel pump beneath:)

I do believe Paul is somewhere between Perth and Adeliade at the moment, looks like we're waiting a bit longer.

Cheers Tim. And please pass on a big thanks to your boss:D

Guys, I thought this was a SAU bbq for SAU members, and their guests. Lets try and keep it SAU or we will need a fridge truck just for the meat:)

Summary time: Spend 2.2- 2.4k on a highflow, you will get the same power at 1.2bar that a stock turbo will make at 0.85bar. Plus its exchange price, so add another 400-600 for the sale of your old turbo that you will miss out on. Total cost $2700 to $2900 approx (may be a bit more may be a bit less), you still have a high flow turbo, ie made from a second hand stock item. And you still have to fit the turbo yourself. HKS - you can buy one in excellent condtion for 1.5-1.8K second hand, sell your old turbo to cover the cost of fitting - cheaper turbo, more power, cost 1.5-1.8K fitted. there you have it.

No, do a search cos there is a thread that goes into infinate detail of fitting the pump - a step by step guide. Its not real brain surgery, but its not a 1/2hour swap-out like the GTR pump

Well we agree on something:) I think the missunderstanding was that this post gave me the impression that you were saying that JimX's plenum was robbing him of between 20-40rwkw. I dont understand how though ben ellis putting down 290rwkw with stock plenum (and head gasket;)) is relevant, as it has been demonstrated on many occasions that power well in excess of this is possible with the stock plenum. My point was directed at what I perceived to be a criticism of the efficiency of a front facing plenum when it obviously is no less efficient than the stocker.

would be nice from time to time:)

http://www.apexi-usa.com/documentation.asp they have downloads of the manuals there, might help.

Would this still be the case if he is already running an aftermarket cooler? I was under the impression that a cooler upgrade from stock could be worth around 20rwkw? Still, at 1 bar, you would expect around 215-220rwkw, if you stubract the 20rwkw (you indicated this to be his loss due to running rich on front cylinders), you are saying he would be making 235-240rwkw with the stock plenum and turbo at 1bar. I doubt it. Didnt the GCG (Ben Ellis GT-T) highflow make around 230odd at 1.2bar?

JimX, can only agree with you, as BOOSTD was making close to the same figures you are quoting with 1bar and stock plenum (also indicates to me that you have one of these freak 95ecus?), so even 20kw difference would not allow you to be making that sort of power, as it would imply with a stock plenum you would be making 235rwkw at 1bar. i wouldnt bother trying to change the injectors until you are getting it tuned. I used powerfc and upgraded to 550cc - resulted in running rich even with correction. To work out your correction as a percentage, just divide 370 (stock injectors cc) by the upgraded injector size, then multiply by 100. So if using 550cc injectors, the correction would be 0.67 (or just a bit over to be exact).

Yep, breaky at 9, but wont be all day as they have put us in the car park, so it will be a case of head back out at lunch time for lunch. this is because the track is putting its own sausage sizzle on and dont want us encroaching:) Pretty sure TIMMMAYYY and I have everything wrapped up at this stage, ie food, bbq and bits. I am just waiting on the final word from T-man. Looks like 30 people roughly who have said they will be attending.

Fair enough then, sorry I thought it was the stocky:D definately worthwhile comparison then. What size were your before and after coolers? What plenum are you using? Just be careful with number 6, one bad batch of fuel or hot day and you may have problems. Are you using stock injectors? Might be worth getting your injectors flowed and then putting richest to 6 - leanest to 1 as a safeguard.

JimX, I think it is really hard to do a before after comparison on a plenum if you do the cooler at the same time. A decent cooler will make alot more power than the stock item so it would be impossible to be objective about the plenum.
