My 17x9.5 +18 with a 10mm slip on clears my fronts. Id say due to a smaller caliper on the rear I wont have any clearance issues!

After many years i finally got around to tuning mine. RB25, TD06 20G 10cm rear, on e85 with all sorts of supporting mods. 17psi straight off the external wastegate so no more boost was added with my boost controller due to the rear brakes sticking on. Keen to get out and drive her now thats for sure!! Will re book for more boost after the new year!! Really happy with the results.

Yes sorry E85. Will push over the 300kw mark once the boost it turned up. 350kw may be possable apparently as she has heaps left in it.

Garage 7 just finished tuning mine today. Boost is straight off the wastegate spring 17psi and boost controller not dialed in yet as my rear brakes locked on witch put a holt to the tune. Engine: S2 RB25DET Unopened apart from cams. GTSR exhaust manifold Kando TD06 20G 10cm with 45mm turbosmart hypergate 3inch turbo back exhaust-Kakimoto cat back Splitfire coilpacks Tomei pon cams 256 8.5mm lift Adjustable Tomei exhaust cam gear N1 oil and water pump 1000cc injectors with top feed fuel rail-Tomei fpr Freddy intake 600x100x76 intercooler with custom/short piping Denso intank, 044 external and 2l surge tank 52mm radiator with 2x12inch craig davies thermos HKS 13 row oil cooler with grex oil filter relocate block That's all I can think of at the moment. Will be rebooking after the new year for 20+ pound run.

Have you got it tuned yet? Mine was a doey POS with a standard ecu fmic, exhaust and more boost, then installed a power fc and put a "home" tune into it witch lived it up a little over last summer. Now shes at the tuners to have her tuned by the pros and a few little things addressed at the same time. Id get a retune able ecu or have one supplied by your tuner, save 1k and drop it off that way you are covered fr a tune and diagnostic work.

You will want bigger injectors dude. Following this thread as i have a forged 3l on the go atm. Was thinking of a T67 but I will wait for results and figures from others first!

Just measured mine and the rear muffler definitely doesnt step down below 3 inch. If anything the "muffler mesh" gets slightly larger inside. I cant say what the ressie looks like inside but mine is bran new maybe a rejigged exhaust over the years?

I am only guessing here but I'm saying my restriction is going to be my Kakimoto exhaust, I have a TD06 20G with the gate welded off the side so I didn't spoil the manifold. Will wait and see what results mine spits out in 5 days.. And if the exhaust manifold is upto the task or not.

Mine is getting tuned on the 20th. She will crank 300 and unopened apart from pon cams. Will update when I have it back in my hands if she doesnt kick a leg out the bed!!

I have had a few issues come out once I took it to the machinists, turns out she needs to be opened up 20 thou witch means new pistons. So I ordered some CP flat top pistons with rings and I will also be getting some sort of forged rods too, the idea of a standard rebuild has now gone out the window... Everything else above I will still be going ahead with but I may change over to a neo head

Will let you know in the up comming days Timmy. Sussing what funds I might have before my tune!!!

​Alpha have a eta on the adaptors? Keen to get my hands on a set haha. Keen to see updates on E85 too! Keep it up.

Ok so got a call saying the block needs to be opened up 20 thou so I will need different sized pistons and rings. Wanted to keep costs down a little but guess I may aswell throw some forgie slugs in there. What are people using and are happy with? Also thinking of swapping it over to a neo rb25 head so should i be looking at flat top pistons? Thanks guys

​Interested in the Intake depending what it comes with?

I am thinking of re doing my catch can so should i have the oil drained back to the sump from the can even on E85? Making sure it has baffles and separaters would be the best option? Any off the shelf catch cans that work great? Or should i opt for a custom jobbie?

Thanks guys. I have told the machinist to go ahead and fit the grub screws as piece of mind (so I can sleep at night) Issue with balancing the bottom end is everything that will be swapped over is in the car currently. Could wait and build it when I rip it apart but it defeats the purpose, been mainly street driven I wont be screaming down the road so most of my changes will be under 5000.

That is on my list of to do's when its time. The ones in the block I have enlarged to 9.5mm but I may drill them out to 10mm and ill do the same to the head.

At page 54 in the oil control thread and want to know if im heading in the right direction or not. Not going to make it another one of those threads as I have searched for weeks and this is what i have come up with. Long story short I pulled apart a running rb30 to freshen it all up and to have it ready when my 25 grenades itself, main reason was to do the oiling mods and freshen it up for boost. Block is currently at the mechinests getting checked out, acid bathed, honed, decked and having a wider oil pump drive fitted and grub screwed. Bottom end: Cleaned and inspected pistons/rods Drilled out oil returns to 9.5mm Die grind rear galliries to suit headgasket Reassemble with new rings bearings. ACL race series? Larger/baffled sump Head to sump drain/vent? ARP head studs ARP rod bolts 2x1.3mm restrictors-keeping vct and N1 pump RB25 head - VCT: Strip, clean, inspect, skim and new valve steam seals Drill out oil returns to suit block - 9.5mm Rear head drain fitting External vct mod Fuel cell foam in covers? Meat added to the head around the vct Old engine onto new: N1 oil pump - With stronger gears N1 water pump TD06 20G 10cm - Small but be super responsive holding back top end power? Bran new RB25 balancer Vented catch can with -10 fittings Poor man pays twice and I have learn't that so im not going to skimp out, but at the same time I want to keep a lid on how much I spend otherwise I would have ordered a 3.4ltr stroker and gone all out. Car is/will be mainly street driven with the odd track day and hill climb. Thoughts? Thanks

Keen!! Let me know I have my rotors and Brembos ready to go!!

Keen for a GB on the rear brake adaptors. Bought their front kit and it works wonders!!

These still available? Noticed the thread is pretty old.

260lph. Only has to feed my 2ltr surge and then a external feeds my rail. Will be more than enough, not sure what it would do on its own though.

Just to inform people i purchased a Denso intank E85 compattable pump as per my tuner. Will be installing it sometime this month so all should be good now I will be getting rid of the 040!

Drill a few holes into it! Highflowed to the max

I searched for a couple of years before I landed one. even then it was with out a manifold cover. Found a cover the other year and I think I got lucky with mine, would have been $1500 all up but a few years ago now. Honestly worth it for the sound IMO.
