Here you go Jez

As far as I know, it's a untouched RB25. Full boost is actually 5750rpm lol, as you can see it's a slug to drive off boost too.

I've spoken to Eiji and they do make a 10cm rear for my turbo so I'll probably get that sometime next year.

Really wasn't expecting it to be THIS laggy, live and learn I suppose.

wow laggy and no power at all! im selling a td06 that will make best part of 300wkw and be way more fun than that if you keen to move on

Honestly. pull it off and count the blades, measure the wheel diameters. Along with what others have said its possible that the wheels are not what you ordered and its some other beast all together. With sooooo many turbos its not a stretch to see the wrong spec turbo being delivered.

for that setup the 12cm is no good.

count the blades, measure the wheel diameters... its possible that the wheels are not what you ordered .

Owners comments were that it's a TD06-20G, with 12cm housing.

By my reckoning that's broadly equivalent to a GT3571, and a 1.00A/R turbine housing. Looks much more like something you'd see on a reasonable sized diesel eg. Landcruiser 1HZ.

Of course it will be slow to respond. Simply wrong spec for the engine and application.

It's a TD06S and it is a T3.

Spewing eh! Ahwell I got it cheap ($600 via Ebay special). Atleast it's fixable, just a pain in the arse lol.

I wonder if Raz' 10cm rear would fit my turbo, hmmmm.

Cheers for all the help guys :)

back on topic tho id say put some more boost into and get it back on the dyno but def 12cm rear is no good

hey guys

sorry too start again but there is 240 pages and am in need of a new turbo and cant be bothered going through the hole thread.

i am looking at around 260-280rwkw on my r34 rb25 neo.

my supporting mods at the moment are

full 3" exhaust

fmic

hks low mount mani

hks 38mm external gate

pod filter

apexi pfc

greddy profec b spec 2 boost controller

walbro 255 fuel pump

370cc injectors

will most likely be getting a set of 660cc injectors shortly.

what would be the recommendation for that kind of power figure with minimul lag?

thanks guys.

Predicting strong torque between 5-8000rpm. Going by the pic associated with the post it's optimal use is on a drift spec engine.

That's pretty high up in the rev range, out of interested, would a 10cm housing start the torque down at maybe 3500rpm or so? something?

Get a T67-25g it'll make that power easily. Just so happens I have one for sale. ;)

With stock-spec engine internals (ie cams, CR) in a 25DET that seems to be commonly achieved with the 10cm housing. The 12cm and cams should result in pushing the torque curve to the right, probably a good thing for a drifter with clutch kicking.

Can't readily see why the 20G comp would be the thing of choice over a 25G for that performance target. Much the same situation with the Garrett range GT3076 vs GTX3071, the performance outcomes are lineball because the smaller comp has to spin faster to pump the air-mass.

That said, it's an option that should hit the nominated power range without too much problem.

    • Yup. You can get creative and make a sort of "bracket" with cable ties. Put 2 around the sender with a third passing underneath them strapped down against the sender. Then that third one is able to be passed through some hole at right angles to the orientation of the sender. Or some variation on the theme. Yes.... ummm, with caveats? I mean, the sender is BSP and you would likely have AN stuff on the hose, so yes, there would be the adapter you mention. But the block end will either be 1/8 NPT if that thread is still OK in there, or you can drill and tap it out to 1/4 BSP or NPT and use appropriate adapter there. As it stands, your mention of 1/8 BSPT male seems... wrong for the 1/8 NPT female it has to go into. The hose will be better, because even with the bush, the mass of the sender will be "hanging" off a hard threaded connection and will add some stress/strain to that. It might fail in the future. The hose eliminates almost all such risk - but adds in several more threaded connections to leak from! It really should be tapered, but it looks very long in that photo with no taper visible. If you have it in hand you should be able to see if it tapered or not. There technically is no possibility of a mechanical seal with a parallel male in a parallel female, so it is hard to believe that it is parallel male, but weirder things have happened. Maybe it's meant to seat on some surface when screwed in on the original installation? Anyway, at that thread size, parallel in parallel, with tape and goop, will seal just fine.
    • How do you propose I cable tie this: To something securely? Is it really just a case of finding a couple of holes and ziptying it there so it never goes flying or starts dangling around, more or less? Then run a 1/8 BSP Female to [hose adapter of choice?/AN?] and then the opposing fitting at the bush-into-oil-block end? being the hose-into-realistically likely a 1/8 BSPT male) Is this going to provide any real benefit over using a stainless/steel 1/4 to 1/8 BSPT reducing bush? I am making the assumption the OEM sender is BSPT not BSPP/BSP
    • I fashioned a ramp out of a couple of pieces of 140x35 lumber, to get the bumper up slightly, and then one of these is what I use
    • I wouldn't worry about dissimilar metal corrosion, should you just buy/make a steel replacement. There will be thread tape and sealant compound between the metals. The few little spots where they touch each other will be deep inside the joint, unable to get wet. And the alloy block is much much larger than a small steel fitting, so there is plenty of "sacrificial" capacity there. Any bush you put in there will be dissimilar anyway. Either steel or brass. Maybe stainless. All of them are different to the other parts in the chain. But what I said above still applies.
    • You are all good then, I didn't realise the port was in a part you can (have!) remove. Just pull the broken part out, clean it and the threads should be fine. Yes, the whole point about remote mounting is it takes almost all of the vibration out via the flexible hose. You just need a convenient chassis point and a cable tie or 3.
