Ok I rang up king springs, the said the springs are progressive rate from 135-180 lb/inch. That sounds excellent, right on Sydney Kids recommendation! I rang up whiteline (they said hello red ranger) and they said they dont sell springs anymore. wtf

The stock impeller is ceramic. This is why there are so many stories of the standard turbo dying. Imo half the reason for a high flow is that you end up with a stronger more heat resistant turbo.

I thought the standard GTST turbocharger was plain bearing not ball bearing??

Shock absorbers do not have a stiffness rating, it is very complex. If anyone has any experience with them it would help a lot. Just got a quote for the koni's and it was $504. Not bad. Unique Autosport has the bilsteins for $690!

Hi All, As the topic suggests which shocks are softer (ie nicer for the street) on the rear of a 34 gt-t skyline: Bilstein Rear Shocks (non adjustable) part number B46-2108 Koni Sport Rear Shocks (non adjustable) part number 8040-1226Sport If anyone has any experiences with these that would be fantastic. I want the softest good suspension for a 350mm wheel to arch height on the rear of my R34 GT-T.

Hi All, As the topic suggests which springs are softer (ie nicer for the street) on a 33 or 34 skyline: Whiteline rear springs part number 73176 King Springs rear part number KDRL-61SP If anyone has the spring rates that would be fantastic. I want the softest good suspension for a 350mm wheel to arch height on the rear of my R34 GT-T.

$28 turbotech boost tee and spend the rest of the money on more worthwhile mods.

a malpassi is never going to be more reliable then a genuine nissan one. plus if you dont raise the fuel pressure over standard then whats the point in having it. my theory is you want to keep as match factory stuff as possible, minimal mods required for a safe reliable setup. your 550cc injectors will supply plenty of fuel for you power level so there is no problem there.

Main reason is that a tune is dependant on the fuel pressure it is running at. So if the malpassi fuel reg is running a particular fuel pressure then you go and change it later on, the tune will be out. Running the stock fuel reg just removes one other thing that can be incorrect. Genuine brands are normally of very good quality.

Plus I thought HKS rate their turbos at only 15psi.

R31Nismoid dismissed me asking this question in another thread. Overall consensus of e85 fuel was that you seem to be able to get more power out of a particular sized turbo then what you should. Therefore its better to go on the smaller side for a particular power level. Although R31Nismoid does have a point that a full retune is quite costly and there would be better ways to go to get more power (upgrade turbo). As you said the problem will be the standard injectors as you need 25% more flow just to maintain your current power level. And is it worth the risk of potentially ruining your turbo.

Sweet engine bay Nytsky! As quoted previously, turbo dump pipe should be as big as possible. Thats why you see see turbo drag cars just have enough piping to direct it away from where it might melt something and that is it. Bigger = better after the turbo. Obviously on a street car there are physical limitations that you have to work with.

Yup Sold!

Ok got the clutch installed yesterday. After copping lots of abuse from the japanese mechanic about why I didnt just fit an exedy HD clutch. He kept saying that I fit another standard one, I kept saying no its not standard etc etc. Whatever, so I jumped in the car and first of all thought they hadnt actually changed the clutches cause it felt the same as standard driveability wise. Drove sedately for a while and yeah the gripping point is very slightly narrower but not noticeable. The driveability is sensational. Then came time for the real test, gave it some stick in first and went to do a quick change to 2nd, clutch grips and the rear wheels start spinning / axel tramping! Mind you I only have 190rwkw so Im not testing it out power wise but what a difference. I have put more power to the side now, next issue dam AXLE TRAMP!! So far the clutch is exactly as promised, very happy. Dont listen to silly mechanics!

Thanks, Have you got any comparisons between 6 bolt oem style and 3 inch vband ?

If it harmed afrs then noone could use it. You havent specified what octane booster you are talking about. If it is 108 octane booster then adding 108 into 110 octane fuel is not going to help is it. If you take the time to spell out your scenario people will take the time to help you out.

Is this turbo housing 6 bolt oem dump pattern or 3 inch vband? That dyno is fantastic, its up around 300rwkw for a long time not just at peak rpm! I have heard the 6 bolt oem style is restrictive, do you find the 3 inch vband is better?

Not sure why but that looks really weird. I would get the justjap bellmouth stlye one for $180-200au. The difference between bellmouth style and split will be bugger all on a standard turbo.

Read the post above yours by KiwiRS4T. The GCG highflow is a garrett ball bearing core in the standard turbo shell. That is perfect for what you are talking about. Will make more than 230rwkw easily. Sounds like an excellent price too.

Price drop $120!!

Oh crap why mild steel?

The CES one is a 1 piece item that covers both the dump pipe and front pipe. Again it says different part numbers for R33 and R34 which is expected: http://www.cesracing.com.au/products_2.htm Although it is quite pricey! My opinion is these dumps only fit up to the standard exhaust housing so I dont think its worth getting a super dooper one. If you are serious you wont be using the standard exhaust housing anyway.

My understanding is the dump pipe is the same across models, its just the front pipe that is different. So if the dump pipe and front pipe is merged into a 1 piece item then yes the R34 GTT one will be different. I just bought one of these for my R34GTT, it says R32, R33 and R34 and I made sure with the seller. Although I havent tried to fit it up yet. http://cgi.ebay.com.au/ws/eBayISAPI.dll?Vi...e=STRK:MEWNX:IT See how this dump pipe says any model R32, R33 or R34: http://www.justjap.com/store/product.php?p...=276&page=1 Whereas the 1 piece dump pipe and front pipe combined has different part numbers for 33 and 34: http://www.justjap.com/store/product.php?p...=276&page=1 http://www.justjap.com/store/product.php?p...=276&page=1 This is another one on ebay that says it fits R32, R33 and R34 (again it is just the dump pipe): http://cgi.ebay.com.au/NEW-EXHAUST-TURBO-D...=item5632103958 But this dump pipe says it wont fit both R33 and R34 like you said: http://www.gktech.com.au/front.asp?pid=11&...uctID=RBXX-DUMP So I am confused, but I think I trust just jap the most. Hope this helps or prob just adds to the confusion!

Nice work! Its hard to see how laggy it is as the axis is in road speed not rpm. But it sure looks to sit at 300rwkw for a long time!!! So you mean the turbo purchase, the installation of the turbo and the tuning was $1000?? Or excluding the purchase of the turbo?

All I know in practice is that the best launching ls1's and skylines have standard rear suspension (excluding full blown drag cars).
