GT30 time now so I need a bell mouthed dump/front and inlet pipe to connect the 4"/100mm inlet to the Z32 in the std airbox position - and retain the std recirc and breather plumbing . Black rubber/silicon joiners too if possible .

I rang Liverpool Exhausts and they have nothing off the shelf and would need car to fit , difficult since this dryer isn't fitted yet .

It sounds like Mick or Scott may be able to make these pipes up provided they have jigs to do it because you can't have my daily driven car .

I just need functional stuff that's neat and inconspicuous if possible so the changeover is quick and painless . Not going to argue over dollars because the stuff you turn out looks pretty good .

For the record the dryer is a GT3076R with the GT30 IW five bolt outlet side like an XR6 has only in 0.82AR . Externally identical to Mickos GTX3071R in every way .

If you can help me out please reply or PM , thanks in advance cheers Adrian .

I had a good look at a certain white 34 getting a GTX3076 fitted at Edge Motorworks yesterday. There was plenty of room for a 30mm spacer, but the 20mm one looked to work perfectly.

T3 spacers are available in 10 13 16 and 20mm thicknesses , 20 is what I'll try to make sure a T04S housing clears if I ever had to use one ie HTA76 etc .

Sonic or GCG seem to have everything except a bell mouthed GT30IW dump pipe so that will have to be made up to suit .

I know people sometimes go big in the tube size but I reckon 3" should be good enough for 300-330 wheel wasps .

I'm going to use the existing coolant and oil fittings from the GTRS kit .

I'm keen to see how the mid trim GT30R goes , once you make the jump to T3 flanged GT30 based turbos it opens up all sorts of possibilities you don't get with GT28 based ones . This is not to say that GTRSs are useless on RB25s and they are a very easy upgrade on a standard engine/car . Not the tool of choice if you want to double the engines output but lots better than the standard ceramic Hitachi turbo .

Anyway someone here , checkbuzz I think , claims his 0.82 52T GT3076R boosts pretty much like his GTRS did but made more power everywhere . That was on an unopened 33 25 from memory and burning PULP .

If Scotty can tune up maybe 320 and have it drive as well or better than it does now I'll be real happy .

Cheers A .

Checkbuzz either had an issue with the setup or is looking at a dyno sheet. The GT-RS is much more responsive than a GT30 based turbo but doesn't go close to have the legs...as you would expect from looking at the turbine.

Yeah looking at them the GT30 hot side is considerably larger . I wouldn't have thought the 52T cold side would make a huge difference spool wise over a 56T but time will tell the difference between it and the GTRS .

Today I bought the manifold and dump studs/nuts and most of the gaskets and copper washers . GCG doesn't have the 20mm spacer available ATM though they stock their GT30IW dump pipe . Its separate dump tube could be larger and formed to a more useful shape at the turbo outlet flange . I looked at pics of XR6T dump pipes and lots of those are made the same way .

Looking forward to seeing how it goes, and how you find it. There is no way it is going to have the low down punch of the GT-RS - however it should be quite liveable, considering a 56T is. Just a different kind of beast, and one which is much nicer suited to the engine it is on.

Most people seem to think that GTRSs are a 250+ KW PULP turbo and I think the E70 allows me to keep the boost and timing up which made 271 at the rollers .

To make more and have the engine a bit more free spinning means more turbine and housing so GT30 hot side is the way to do it . Lith we know that the GT37 compressors are good but later designs are creeping ahead . The 52T GT37 wheel in theory pumps right about what I want which is in between what the available GTX ones do . Arguably a HTA GT30 may do better all round but I own this turbo so why not use it . When tuned and I get to fiddle with the low load numbers I can draw my line in the sand and know if its just right - for me .

Will post up as it happens , cheers A .

250kw+ PULP is pretty ambitious really - as you can probably tell by "only" making 271kw using E70 etc.

Agreed, HTA would be the way to go if you were in that position but having a 52trim there and knowing you won't be looking for insane power means there is no justification in a big change - any ETA for this?

I prefer a single 20mm T3 spacer if anyone knows of any in Sydney , GCG Sonic and Liverpool can't supply ATM .

The studs I have are 41mm so around 20 the limit allowing for the turbo flange and nuts .

Does anyone have a 20mm T3 spacer they can sell me , prefer one 20 to two 10s .

Timeline probably a week after I have all the bits .

    • Hi. Can someone tell me what brakes(and mainly WHERE) can i buy brakes on R34 GTT? I bought some EBC which SHOULD go on my car(i have GT but it has GTT brakes) but it does not fit, Brakes are "too" small(296mm) Are 310mm be good or? I have 17 inch wheel so no "big boys" but for me driving i just need one that fits and i can get here in EU/Czech.
    • Since winter isn't that harsh anymore in Poland, i will definetely drive it 365 days a year 😉. But if the snow hits i will try it for sure and let U know. Only swap i am planning to do is of course R34 GTR front 😍.
    • Hey. Very valuable information about pitwork, I will pay attention when buying any consumable parts 🙏 As for the carpets - I got a handful of information from nengun, from which it appears that indeed the carpets for the driver's side are OEM. They are not able to show me any pictures due to the long chain of different sales entities but after I place the order, as soon as the goods arrive at the nengun warehouse from which they will send the shipment to me they can send me photos and if my purchase differs from OEM I can immediately return it / cancel the purchase. I think I will give it a try 😉. Of course i'll let you know what's what as soon as i get them P.s. I know the topic is not relevant to the thread, but both nengun and amayama have these SICK 😍 trunk room lamps available. Do you know anyone who ordered them? I need to have one in my car
