Forged RB26 (Sleeved block, 87mm Pistons, rods, rod bolts, head studs, N1 oil pump with billet gears, Tomei sump baffle, Tomei metal head gasket etc...) -7 turbos rebuilt with larger billet wheels Nistune ECU (Latest update - Flex Fuel, Boost control etc) Standard Exhaust manifolds and intake piping (Port-matched to suit bigger wheeled turbos) 1250cc Injectors 460LP/h fuel pump Nismo AFM's Standard Air-box with CAI and K&N panel filter Splitfire Coil packs Kelford L182a cams Greddy cam gears Plazmaman 76mm intercooler 391rwkws @ 24psi (how it's driven) E85 417rwkws @ 26psi (airbox just cracked open) E85 335rwkws @ 20psi (how it's driven) 98RON

Well I think I can say I pretty much achieved what I set out to more than 2 years back... I've got myself a NisTune cable so will try and get some logging done on my next R&R to show the rather impressive response achieved (as they dyno graphs obviously don't show it) given I was set on staying low mount twins. I know I could've achieved so much more with a modern single but I do honestly feel far less disappointed than I had expected to... Finally got round to fitting the correct boot badges as well...

Just got word from the tuner it is currently making 323rwkws @16-17psi... on 98RON Fuel pump appears to possibly be an issue (Walbro 460) getting very warm... Looking into it further now...

that's a ticking time bomb if you still have the stock turbos.............

^^^ This... I did exactly this 2-3 years ago when 32 GTR prices start heading north... The GTR is the weekender I'm slowly resto modding and the the S15 is the 'budget' racecar...

got an email back from Bilstein Australia themselves who actually appear to have bought Quadrant suspensions (in Victoria) so may have a solution, they are calling me back tomorrow.

finding someone who will rebuild them is the only thing stopping that from happening... here in oz it appears everything these days is throw away and replace (boy i sound old saying that) ?

I don't mind the idea of the 'street essentials' in stealth black...

i seriously need to remember to grab my popcorn 'before' venturing into a few of these threads ??

yup, exactly what I was thinking whilst perusing their site this morning ??

This was what I was going to do... But the guy who I use for tuning and bits & bobs I can't do here in Adelaide said they'd had issues with MCA recently when there was warranty issues, has kinda put me off ? I had just been reading up about 'The street Essentials' (shows how long it's been since i looked at suspension) they just used to do 'blue', 'red, and 'gold' haha...

So a little bit actually happened on this R&R trip home, not all good but not all bad... I put her on club rego which significantly reduces the cost of registration and insurance here in SA (win, win)... After a few minor but frustrating teething issues with injector plugs not actually being standard and dramas bleeding the ATTESSA she was finally turned over (boy had i missed that RB sound)... She was then put on the dyno for a few hours to run her in and do some basic tuning on 98RON. Very happy with the results on pump fuel, just running wastegate pressure (12-13psi) ended up with 279rwkws from memory, video shows the run before at 275rwkws... Initial feelings from these turbos is impressive, the response is very transient and feels better than what i recall my -7's did... Whilst out and about putting a few kilometers on her i was thinking to myself she was feeling a little stiff, just put it down to me being a couple years older than when i last drove her but once i got out for the first time i noticed one side was sitting far lower than the other at the rear, after hopping underneath it appeared as though one shock had compressed and not rebounded, so I got her home and pulled the rears out and sure enough this was the case as seen in the below photo ? So now I weigh up whether to rebuild the rears as i did the fronts (really like the feeling the bilsteins give) or I look into some coilovers... The cars driveable so not a huge urgency... I dropped her off last night before flying back out to site this morning so fingers crossed the 98 tune will be completed along with the E85 over the next 2 weeks... Very excited to see what some E85 in her guts will do IMG_0707.MOV

cheers mate, the patience has worn thin a few times but I think it's all been worth it

2:16 and 240km/h at 'The bend' is impressive, hopefully see you out there one day

I think that's the answer i was expecting I for one certainly think it will be worth it in the end, do it once, do it right ?

Is this one of those projects where you knew what you were getting into from the start or has it just snowballed the more you delved?!?

ye fingers crossed I'll be driving her once back in adelaide in 2 weeks

ye i'm convinced now it's all come together thankfully... got a bit of a mix in the engine bay of gunmetal grey, black and wrinkle black... will have to see how it all looks once fully complete...

Starting to finally gain a little traction over the past week or two...

love what you're doing and being different, massive props. Love all the mods and the way you are/am/have been going about them... Just one question, money doesn't seem to be a massive issue so i'm curious why with all the quality of parts you've used in most areas you haven't gone with a nice modern say B/W EFR turbo etc that would almost certainly achieve your desired 'under the curve' results!?!? The HTA definitely has it's positives but in this day and age isn't exactly a modern piece of kit?!? Edit: some more reading about the HTA turbo's, they seem to be a good thing that I possibly haven't heard too much about being more an Evo turbo upgrade etc... Keen to see your results...

NSW and 'P' platers legally being able to drive the ADM version hey The amount of messages I've gotten about mine from kids in NSW is bordering on ridiculous ?

ye I've got the kinugawa version of the gtx2867 and it only starts to awaken around 19-20 psi... go the smaller version if you only want 220-230rwkws on E85...

Slow progress but progress nevertheless...

Welcome. Great choice of car. Welcome to never having any spare money I have some N1 / -7 turbos for sale if interested.

I went ATI, far less horror stories than with the Ross equivalent...
