R32 TT

Do any of the boost controllers allow you to set boost levels depending on RPM? For example - supposing I want to limit boost to 1.2bar at 5000rpm and slowly ramp boost up to my maximum boost of (for arguments sake) 2bar at 8000rpm? The reason I ask the question is that since boost is "resistance to airflow", as you go up the RPM range, the valves are only opening for much shorter periods, and so while you are reading say 1 bar at 6000rpm, you're probably only getting half the amount of air in as you are at 3000rpm when also running 1bar... ( is that theory right?) So I was thinking that an engine under load 4000-5000rpm might not like 2bar being belted into it, (a bit like a shot of nitrous too early in the revs) but could well handle it up around 7000-8000 rpm? If a boost controller is set at 1.5bar to "suit" the 4000-5000 rpm range, then am I getting less and less air into it at higher revs as the valves are opening and shutting faster and faster and hence building up back pressure? (ie reading same boost, but getting less air-flow?) Thoughts?

Hi guys, Just a question on Ceramic coatings. I have just bought some s/h Mines Dump pipes. I already have some HKS front pipes. New turbos are on their way. When the whole system is apart and out of the car, I was thinking of ceramic coating the Dump Pipes and Front pipes to keep the heat in and therfore keep the gas velocity up. (as well as keep a little heat out of the engine bay). I have heard/read of ceramic coating causing issues. Some say only coat the outside of the pipe. Some say do inside and out. Some have even said don't do it as it makes the pipes crack?? My gut feeling is to do both inside and out, and that the ceramic would actually make the pipes last longer as it would be keeping the extreme temperatures from reaching the actual metal itself. Then of course there are a few different flavours of ceramic coating... Any experiences? Recommendations? Cheers, Matt.

Yup, sure are! Missed an opportunity to sell to one of the guys in this thread because I took a couple of days to get back to him and he bought some others... Haven't really done any more advertising - so still got them.

Where did you get the MINES dumps from and how much did you pay? I am trying to locate some - or perhaps Tomei Dumps as I think they are similar. I'm not convinced of the split pipe design at all. Did you have to mate them to MINES front pipes? Or are most Front Pipes and Dumps interchangeable? (ie do MINES dumps match up ok with HKS Front Pipes in terms of flange and bore etc?)

Looking for Tomei, Mines or similar dump pipes for twins on GTR. Prefer not to have the split type like HKS/Trust.. Any out there?

Excellent - let me know how it goes. I'm looking at these as one option for myself - would really like some feedback. Did you fit different dump pipes? Injectors to suit? etc?

Have used it in previous cars yes. Its the ultimate in shear load protection... If you really want the low down on what Redline product for what application, give Tim a ring at WestRacing on 08 94461913. He's full bottle. On the oil change interval. Well - how long is a piece of string I guess. Depends how hard its driven and what parts are getting loaded the most. A 6 sec Drag car throws away the oil after one race meet (or more!) even if the oil is untouched. For me, I'd prob check the diff oil at 5,000km and 10,000km to see how its fairing. If it looks good I'd be happy to leave diff oil in for 20,000 to 30,000km no probs if its a good oil. A race car probably wouldn't... Let's face it though, No one ever did any harm changing their oil a little more often than needed. So if you can afford to change it more often - do it.

I'll do that! Gimme a few days - she's in the workshop having Motec fitted (yay!) (hmm.. wonder if I can 'tune out' the vibration...) But yeah I'll let you know,

Hey Mike, I am going through exactly the same process. Am thinking about GT-SS or the GT2560r like you. I understand that the GT2560r more or less IS the N1 turbo and I have also heard that the GT2560r IS the GT28RS (disco potato), Garrett implemented a new naming scheme apparently. anyhow, back on subject. How did it go? Do you have them fitted? And most importantly what is their response like? I am after quick spool up and hence I am looking at the GT-SS also. Matt.

Redline 80W140.

Yep, they sure do. I just fitted the Nismo ones about 4 weeks ago. My existing bushes had split and leaked the silicon(?) fluid out of them. Putting the Nismo's in really has turned it into a go-kart.. but of course since the stock ones were shot - you would expect that. I got them straight from a Nissan dealer here in Perth. Watch out though, they are a little over $100 each (and you need 4) They are a solid black rubber material. I don't know if they are stiffer or not that Poly bushes, but I think Poly is a third of the price. (I learned that after I had bought the Nismo's) Also, NVH has definitely increased for me. In fact I even feel a bit of a vibration through the seat between 80-100km/hr. This may be "something else" vibrating that needs looking at - and perhaps the bushes have just brought it to my attention. Below 80km/hr, they feel fine. Point is, the vibration wasn't felt prior to them being fitted.

No they haven't been sold as yet. Have one guy looking at them - but not sure yet if he wants them yet. I'll try your number a bit later in the day.

I am not 100% sure of this. But I asked the suspension guy over here who I deal through and he's pretty sure it only fits R32 GTR and nothing else.. disappointing huh.. Anyone know different?

Ah yeah. Good point . They are height adjustable, but my workshop guys don't "think" that they are damper adjustable. Might have to take it down to one of the local workshops that know Teins and get them to have a close look and tell me which sort they are.

Hi Guys, only bought the car a little while back and am not full bottle on the various types of Tein available, so can't give you a model number. They are currently on the car so if you're in Perth, message me and you can come and see/feel the ride for yourself if you're interested. Reason for sale: I'm getting old and soft...:whatsthat ... and they aren't either of those things. (acutally they don't ride too bad, but I am going for Bilsteins - you be the judge - probably great for drifters) I am told they should be worth around $800 - $1000 ? Offers would be considered of course. If you want to know more about "what sort are they", please just tell me what to look for (colour, shape etc?) and I will describe them better. Cheers! Matt.
