Nabil Posted December 3, 2006 Share Posted December 3, 2006 (edited) Just purchased my GT3071R 56 trim, 71mm compressor wheel 4inch compressor cover T3 flanged with 0.71 exhaust a/r, which mates up with the stock dump-pipe. Cost me $1900 from Rotomaster in Melbourne Would of cost me a further $100 for a GT30 style 0.63 ex-housing, but would of cost a further $300 for a custom dump pipe. Oil and water lines were custom made by HIS and cost me $330- all braided except oil drain pipe. Some bango fitting from the stock unit were chopped and re-used. BTW - Turbo needs a 10mm spacer between turbo and manifold, as comp cover is quite large. Stay tuned for further updates...(more pics/ dyno graph/etc.) Edited December 3, 2006 by Nabil Link to comment https://www.sau.com.au/forums/topic/145752-project-gt3071r-in-progress/ Share on other sites More sharing options...
Nabil Posted December 3, 2006 Author Share Posted December 3, 2006 Here are some pics of the turbo, lines and dump-pipe after i assembled it. Link to comment https://www.sau.com.au/forums/topic/145752-project-gt3071r-in-progress/#findComment-2722981 Share on other sites More sharing options...
Nabil Posted December 3, 2006 Author Share Posted December 3, 2006 (edited) The compressor cover was hitting the manifold, so I had to use a 10mm spacer and remove the four manifold bolts. I replaced them with approx. 10mm longer ones Below is a picture of the four bolts that had to be removed and replaced with longer ones. (4 bolts and nuts from Metric Man cost me $6) The yellow rectangle highlights the section of the manifold that comes into contact with the compressor cover.

Nabil Posted December 3, 2006 Author Share Posted December 3, 2006 Latter on i realised that it was not sitting flush with the manifold. The heat shield had to be removed & the bottom right bolt had to be threaded in 5mm deeper as i could not put the nut on it. This is a picture of the set-up when I placed it on this morning at 4:30am (Me and my mate were burning the midnight oil into the early hours of the day. ) the arrow is pointing to the bolt that had to be threaded deeper.

Adriano Posted December 3, 2006 Share Posted December 3, 2006 Will be interesting to see how this turbo/ex housing combo works, what management are you using, what other mods?

Nabil Posted December 3, 2006 Author Share Posted December 3, 2006 Will use a power fc ATM: Mods are: Full 3inch exhaust Apex FMIC (its quite small) HKS GEN 3 EBC BOSCH pump HKS mushroom filter It made 211.2rwkw on 12psi with a SAF-C Cannot wait till this one starts spoolin' Link to comment https://www.sau.com.au/forums/topic/145752-project-gt3071r-in-progress/#findComment-2723164 Share on other sites More sharing options...
Dale FZ1 Posted December 3, 2006 Share Posted December 3, 2006 That looks like a big comp cover - no wonder you needed the spacer. What is the origin of the turbine housing? 0.71 A/R with T3 flange seems a bit of an unknown. Will be very interested to see how it goes for you. One of these should offer response and good power. Any chance of a clear shot of the ID plate with numbers?

Drifterdan Posted December 3, 2006 Share Posted December 3, 2006 (edited) Just curious if this on a RB20 or 25.. I have purchased a GT30 with that .64 option above(have to look into the exact specs of it when i get it). Would be keen to compare if yours is on RB20, though mine wont be tuned till mid Janurary. Are you planning on using camshafts at all cause Id also be curious to see what you choose. Cams are a unknown area to me and any advice I can get would be a bonus lol... cheers Dan.

tridentt150v Posted December 4, 2006 Share Posted December 4, 2006 The oil line comes out lower down and at the side of the block for mine ['98 rb25], did this change? Was it different for earlier models? The photo shows the oil line coming from the back of the block? Just curious........it could just be in the rotation of the housing etc Link to comment https://www.sau.com.au/forums/topic/145752-project-gt3071r-in-progress/#findComment-2723948 Share on other sites More sharing options...

Lithium Posted December 4, 2006 Share Posted December 4, 2006 Damn - some cool things going on with RB25s at the moment. I will watch with great interest at how the GT3071Rs go - I got >< close to going one, but decided a GT3076R in the end. The RB25 dyno thread will be interesting watching soon!
