Ok 5558 on built sr20 is now run in. Boost was uncontrollable due to a mixture of incorrect wastegate spring and a loose block off bung in the side of wastegate.

Went for a quick roadtest to check boost pressure with 8psi spring and its running 14psi. With a 4th gear foot flat 2500rpm pull was cracking gate at 3500-3700 (14psi)

Will tune as soon as i get some time

Ordering from the US is always better for service IMHO.

I used Real Street Performance on a few occasions and delivery was about a week on all orders. There was one odd time when they couldn't ship an item because it was missing a piece from the MFG (the value of non drop ship vendors). That was rectified fairly quickly by the vendor, the supplier was a little slow though and I ended up taking a payout instead. Item arrived at my door, missing the said gasket, within days of telling them to send as is.

They also sell PT's and pricing is as competitive as it gets.

6466 is now on the manifold, and i am now looking forward to cutting myself to bits doing the pipework lol! Also, just an FYI for you simon, you may have trouble with the outlet on the turbo if mounted on the greddy manifold as mine sits rearward moreso than the greddy items, so pipework may have to face directly downwards and do a 140 degree turn.

Pics would be handy :)

Sort your line out?

just waiting on a 12mm metric to -3 adaptor and i will have the oil lines sorted. The pressure pipework is going to be the next interesting part. The thing looks small compared to the 78-33d. It only just fits between the cam covers and the strut tower lol

Hey you guys with precision v-bands, re- the 3" outlet to dump pipe, -the v-band flange welded to the turbo doesnt have a seat for the female flange and the Performance Exhaust at Northmead guy told me I need to get a female flange milled to suit with the clamp and my turbine flange because most of the time the clamps are too wide and the dump has play in the joint . He said it will fit first time but not after if I just get an off the shelf vband flange kit. Is that correct and what you guys doing about that? Where and what size T3 spacers you using, theres some 11mm ones on ebay, mine is a 5558 to go on stock rb25 mani- low mount.

Last question- oil feed and return, any suggestions on fitting sizes and line lengths? Or just let the tuner (unigroup/jem etc) sort that out..

And how much u guys paying for fabrication work, and any recommendations? Pm me if you dont wana post on here, thanks :)

I can preeeety safely say, if its unigroup, let them sort the oil line for you. The 6466 i have was supplied with a machined V-Band flange, looks the goods and mates up 100% primo. I suggest talking to the unigroup guys and leaving it in thier capable hands mate :)

Thanks man, ur lucky you got a flange n clamp supplied as the precision ones are different in size to regular vband flanges and dont seal properly according to the exhaust guy and on the web, can anyone else with this 5558 or other 0.63 vband turbo please tell me where they got their dump flange n clamp from?? And any pics of how the gates welded to the turbine? Thinking if i should point the gate sideways towards the firewall or up upwards like a hat. Turbo will be Low mount on stock rb25 mani

Don't be stupid Paul, there are no compressor maps so they are rubbish.

Lol, not what I said... they are your words. But continue to misquote me to the benefit of being an internet hero.

    • Not sure the US can import anything other than the C34 Stagea's, but if you can and you need to to tow, DO NOT under any circumstances get an M35 Stagea. If it is just as a family car and your country/state allows it, absolutely and definitely get an M35 (3.5L if possible as it is effectively a 350Z) over a C34.
    • Punch your VIN (nm35-xxxxxx) into Amayama.com You can see everything there quite easily.
    • Thanks for that, I'll check it all out. I can always do the brakes last anyway if its a problem.  The 16's are super cool, if they do fit I'll cruise around with them for a bit.  
    • Well, that's kinda the point. The calipers might interfere with the inside of the barrels 16" rims are only about 14" inside the barrels, which is ~350mm, and 334mm rotors only leave about 8mm outboard for the caliper before you get to 350, And.... that;s not gunna be enough. If the rims have a larger ID than that, you might sneak it in. I'd be putting a measuring stick inside the wheel and eyeballing the extra required for the caliper outboard of the rotor before committing to bolting it all on.
    • OK, so again it has been a bit of a break but it was around researching what had been done since I didn't have access to Neil's records and not everything is obvious without pulling stuff apart. Happily the guy who assembled the engine had kept reasonable records, so we now know the final spec is: Bottom end: Standard block and crank Ross 86.5mm forgies, 9:1 compression Spool forged rods Standard main bolts Oil pump Spool billet gears in standard housing Aeroflow extended and baffled sump Head Freshly rebuilt standard head with new 80lb valve springs Mild porting/port match Head oil feed restrictor VCT disabled Tighe 805C reground cams (255 duration, 8.93 lift)  Adjustable cam gears on inlet/exhaust Standard head bolts, gasket not confirmed but assumed MLS External 555cc Nismo injectors Z32 AFM Bosch 023 Intank fuel pump Garret 2871 (factory housings and manifold) Hypertune FFP plenum with standard throttle   Time to book in a trip to Unigroup
