No it's GCG GTX 2930R I believe.

 

http://gcg.com.au/petrol-performance/performance-4/turbocharger-kits/404/404/nissan-rb20-rb25-low-mount-gt-gtx-29-30-detail

if it's this kit then it'll be 2967 or 3067

keen to see how it goes once you have all the supportive mods like ECU injectors and FMIC..

Looks very similar to the kit I got not the same site however. I'll have to double check I think it could be the 2967.

Yea at the moment my car goes into limp mode every time I go over 4,500Rpm so I can't even see what the turbo's got properly, but at the end of this month all that should be solved and I'll have new Dyno sheets to post up. So I'm still waiting to seeing what the turbo has to offer haha.

3inch turbo back exhaust-Kakimoto cat back

Retuned today-had a few hiccups early on but ironed them out and Decs got down to business.

Only thing that has changed from above is the pon cams have been changed for Camtech 268-9mm intake and 272-9mm exhaust.

22psi and dropping off to 18psi at top end.

326.9 kw ~ 546.8 nm

Happy with the results, think I will leave it alone for a while :)

Yup please, keen to see how it turns out and btw ditch that 2.5 inch decat and get a 3 inch to match the diameter of the rest of the system lol

Does it drive like standard turbo on low rpm? Good response?


Yea it drives better then standard at low rpm smooth and sounds amazing, just recently had my rear housing replaced as I found out my wastegate was faulty it was leaking and getting stuck open :(.

Haha yea.. anyone have a 3" 100 cell race cat they want to sell me :D would be awesome. Or if you know anywhere online to get a good one.

Not to long till my new Dyno results will be posted up anticipation is driving me crazy. 3 weeks without my baby.

Got invited to a dyno day to eat bbq and do some power runs! Stock coil packs were breaking up at the top but that's no big deal since i've got LS packs in a box, just waiting for the new turbo to show up. 327 bhp 289 ft-lb not too bad for a stock turbo with a street fuel map and no ignition tuning. Hah. Looks like the first run made better tq and had a smoother band but it's whatever. Bottom line is the engine is strong and ready to make f**kin power w/the gtx3076r and new ls coils. This is the first engine I've ever built.

First run made 319 bhp 304 ft-lb torque:

Quick update time!

I decided to get some Tomei 256 deg poncams installed along with an adj Tomei exh cam gear and some Kelford valve springs and then get the car back on the dyno to see what we can safely extract out of my setup.

Pretty happy with the final results.

Both the results above are on p98. Just realized I had forgotten to mention that.

"D1 stable" exhaust manifold, essentially a "cheap" steam pipe manifold from what i can tell, 50 mm turbosmart wastegate off the manifold
Madcat intake manifold, essentially a high quality china manifold ( it may even be made in aus ) ( really really good welds )
China spec intercooler,( just jap cooling pro i think ) but with high quality stainless pipe work done.( i will be testing pressure drop next month )

 

( manifolds would not be making any more power than stock ones, if anything they hurt response.)
( i had 444 hp with stock manifolds with a atr43ss2 )

Slight update, Still having afew issues with the car, however the ross trigger kit is working great!! The intention with this tune was to keep the car safe for the racewars weekend so we stopped at 23psi... really need to get the car back on the dyno and turn it right up so the 6266 can do some work!!

    • Seat of the pants assessment of the new intake: The car is way less "doughy" when hitting the loud pedal, especially off idle when stopped or in traffic, I did use a cheapo lazer thermal thingo to measure the temp around where the pod filter got its air, it was between 55 - 60°C, in saying this the car was shut off and not moving, so the OEM intake pipe was not supplying any fresh air to where the pod was when the car was at least moving A weird bonus was induction noise on the throttle in the cabin increased a bit,  I was worried that I was actually going to lose some of that induction noise I love so much, outside though, when I got the daughter to do a WOT drive by pass for me, the induction noise has increased alot when on the throttle, not quite ITB doort, but well up there I'm extremely happy with the results and have been exploring the country roads in the region  As for house mods: 1.New front fence is up and is awesome, it really upgraded how the joint looks from the street, and the added security is nice 2. Electricians have replace some interior lights, and with more lighting in the garage, a few new motion detecting lights out the front above the garage, front room, and at the front door, which I have already found heaps helpful coming and going, also now has fancy pants CCTV all round the house The only hold point for power though is the solar and batteries due to supply issues, although this will happen over the next few weeks 3. I have done a heap of landscaping out the front and I'm almost ready to do a new small retaining wall with some nice blocks to replace the brick and cemented in rocks around the raised garden beds cemented in river stone "was the fashion at the time" the house was built. I currently have a pallet of retaining wall blocks and 2 bulka bags of 20mm blue metal to replace the wood chip that is in the raised garden beds around the house 4. I now have 3 big raised garden beds for out the back to grow some vegetables, about 70cm high, 200cm long and 100cm wide 5. My 2 compost bins are already pretty full with brown, green and kitchen waste from the landscaping I'vedone so far, but they will probably take a few months to break down, so anything else that gets chopped, trimmed, and kitchen waste will just start filling the base of the raised garden beds to about 30cm before I start throwing 40cm of good compost, and stuff, for the vegetables to grow in, I'll need a few ton of compost and soil, but the local supplier can sent me bulka bags of the stuff Basically the logs, wood chips and a few strategically placed rocks for drainage, will give the beds some good organic materials down low to break down over time, and they will hold moisture during the warmer months to save the water in my big arse water tank if we don't get alot of rain So, all in all, the car and house mods are going well, and I'm really enjoying being retired, I sleep in too 0700 and slowly plod around inside until I feel like actually doing anything, and only work in the yard for as long as want, which has actually been alot over the last few weeks,  although when you look at it, it seems that not a huge amount of work has been done,  until I look at the before I started the work pics Happy days and good times indeed 
    • hahaha yeah. Plan is to get side skirts and probably just rear pods. But going to do them one-by-one. I've got a set that I really like from RHDJapen, but that one isn't shipped to AU. So need to find someone who can get it for me
    • Here's an idea, answer the questions I asked you as they are trying to work out WHY the LSD will be binding up in a straight line.
    • You haven't driven many modern cars then have you? Most of them have sfa steering feel with their stupid electric bullshit steering systems.
