yeah and am I right in saying 1 + 1 = 2 ? sorry its just I really had to break it down into lamen terms to find the answer I was after.. cheers none the less.

http://www.skylinesaustralia.com/forums/Rb...&start=220# Its got a few mods, and yeah ill be watching the boost like a hawk.. I dont produce full boost until around 4k, so this test could be interesting to try out whats the actuator look like? hence why i posted the pics .. cheers

I need to disconnect the actuator pipe to run open boost .. I dont have a boost controller yet so apparently this is a good way to see how the car will behave if I did have one installed.. Only thing that controls the boost at the moment is the wastegate spring.. can anyone point me to the right pipe / hose to disconnect to achieve this? Thanks in advance engine bay pics are as follows:

Damn, i think i chose the wrong auction / specs there... i cant find any record of the auction i just assumed it was one like that.. ill take a photo of the turbo installed on the car and see if anyone knows what specs they have.. But yes you are right in saying its the TD05 big 16g type

so should i go out an buy a EBC then?

Yeah thats because we changed the springs around when he was tuning it. Yeah true but I'd put my money on the cheap chinese turbo + setup issues being the main culprit of such high boost for such little power.. Im quite positive a good td05 would dominate an rb25 turbo in most areas but mainly maximum hp unless of course the rb25 turbo is high flowed or something.

Sorry this is the only info i could find on the turbo, http://www.trademe.co.nz/Trade-Me-Motors/C...n-149812251.htm Inducer: 1.89" Exducer: 2.68" Compressor wheel: 16G Turbine Wheel: TD05D This turbo was just a cheap chinese replacement option as I couldnt afford over a grand to replace with a genuine turbo at the time.. I could take a photo of the turbo installed on the car but will have to take off the inlet hose etc, maybe someone could recognise the writing on it if I do that.. If I understood you correctly yes it did have an internal gate that is welded shut and uses the external wastegate instead..

I started it up before, and after about a min or so in idle the gauge was reading 16 In. Hg thats the unit my gauge measures in not cmhg like you said but dont know how to convert it..

haha funny title I cant stop laughing when i read it

well considering mine failed around the 180kw mark that theory is more plausable than ever

who knows, maybe I bought a fake one... but it was $250 NZD and was advertised as a GSS341 "Good for 500hp easy" http://www.trademe.co.nz/Trade-Me-Motors/C...n-197048152.htm

Only thing that controls my boost is the spring inside the wastegate Hearing words like revert back to stock ecu make me wanna pull my hair out, i spent so much getting that link installed all on bad advice.. but I dont really want to get into an ecu discussion so ill stop that there.. As far as throwing the turbo away, the td05 is hardly a lag monster, but considering future power goals etc something like a gt3076 turbo could well be on the cards if i wanna part with heaps of my hard earned cash.

Dumpy is 3'' right off the turbo, not sure what you mean by 'type' but its not a branded dumpy like trust or something. No cat, its a straight through pipe to rear muffler (can get away with that in nz). Inlet pipe to turbo is below, and its a K&N pod. Now ECU is a Link Ver 5, yes the old type.. is probably an area that lets me down a bit although I think this is more evident higher in the rev range and not so much low down.. Was tuned by TrickyTune in NZ so i doubt your familiar with them but he tunes alot of the D1NZ cars that race over here .. I asked him for an 'agressive' tune and he spent quite a while tuning to get the most out of it, timing was tweaked aswell.. compressor wheel is a 16g.

Not sure, ill check next time I use it

i have scratched the issue of exhaust collection being a potential problem on our kiwi forums here: post #41 has a pic there http://www.skylinesdownunder.com/forums/sh...7809&page=2 then on the next page it shows possible alternatives but weather this will fix the lag issues im not sure.. your thoughts?? Car has just had a fresh hub dyno tune in conjunction with its new full three inch exhaust, also being New Zealand we can get away with straight through pipes, no cat or reso's so its loud as.

My walbro ran my engine lean and nearly blew the engine, so i switched to bosch

Probably a question raised in here a few times but looking for a quick and possibly obvious answer... Basically after looking over a lot of other rb20 dyno figures on the results thread it occured to me that I'm even worse off in the lag department than other rb20 owners.. Feel free to look at my dyno printout in the other thread but in a nut shell im only putting out 80wkw or so at 4000rpm then makes all its power before 6000rpm.. (this was on a hub dyno aswell so could well be lower on a roller dyno) http://www.skylinesaustralia.com/forums/Rb...&start=225# Its increadibly laggy with the new 3'' exhaust and previoulsy with the 2.5'' exhaust was not much different. I wanna get some power down early in the rev range nothing outragous just enough to get that turbo spooling a little quicker because 4000rpm is quite righ rpm for only 80kw. Is messing around with engine internals my only option from here? I love the rb20's so dont wanna go out and buy an rb25 just yet.. Your thoughts anyone?

So you cant use a pod filter in Australia? thats gotta suck Australia's laws are so tight ass compared to New Zealand, I have to hand it to our 3rd world approach to things, lets me gets away with a straight through exhaust and ground clearance that turns me into a grader on any gravel road.

Alright so an 18G compressor will fit into a Td05 will it? sounds very tempting although i've got a cheap chinesy turbo on at the moment so dont wanna throw any money at that.. can you or anyone recommend a turbo similar to a Td05 with 18G compressor that I can buy new?

thanks for that link, I actually had a look at that a few days ago but didnt realise it was 83 pages long! let the research begin.

Im looking to get more power out of my rb20det, its running a td05 big 16g at the moment making about 205kw at the wheel.. the link below shows the dyno sheet of a 221kw @ 23psi run that ended up with detonation so we cut the boost back a bit. All mods are on this link: http://www.skylinesaustralia.com/forums/in...t&p=4327859 I believe the 'older' Link ecu is to blame as their website states ver 5 links can only boost to around 23psi at most.. I dont want to turn this into a LINK ECU bashing thread but rather whats the best cost effective way of reaching around 250wkw with my current setup.. Obvious ideas at the moment are: upgrade to a better ecu bigger turbo upgrade to greddy or similar intake plenum Are there other options I've overlooked??? Im personally thinking of getting a bigger turbo and to hell with the lag (got plenty already as you can see in the dyno graph) I dont have to stay with the mitsi turbo's, can easily snatch up a standard exhaust manifold for cheap and revert back to the original flange setup.. But am lost as to what turbo to get, can the turbo guru's help me out on this one? Thanks..
