My engine is still going strong! 11000kms on over 350kw now :D

man those R34 NEO motors are built like german nazi tanks lol

it seems like it's more economical to drop in a R34 NEO motor if a R33 RB25DET motor ever carks it

Yep We're jealous of full boost at 6000rpm with a gtx35

Back again, 372kW @ 1.75bar (1.8bar spiked a little)... motor has not popped and even went to a track day on the 30th of May. Motor did push some coolant, I believe the OEM head gasket isn't too happy

They tend to hold together pretty well! Ill admit mine has had a hard life too! Its been overheated (Well got warm but Haltech shut it down) and also had a LOT of fuel dramas which caused all sorts of bad AFRs early days... I try to keep it off the limiter but it still gets spun to just over 8000rpm when up it haha

Sick effort. Mines close to getting on the rollers. Patience is running thin though

It gets like that! Itll all be worth it on that first drive though ;)

Funny thing is I'm the one doing all the work. Just a matter of putting in the effort after working all day on shitbox cars (skoda). Sometimes all you wana do is sit on the couch and not move lol. Will be tuned within the month though

I would like to be able to say the same. But i give mine a fairly hard time. Seen 2 track days and lots of limiter, although mine is set at 7450 from memory not 8000 haha.

Even driving it very hard, no blowby AT ALL! or any oil/fluid leaks, just running the standard nissan setup. ie linked rocker covers and then a hose to the intake after the AFM.

The thing i am most impressed with is its off boost driveability though, it is insane! Put your foot down in any gear and it just accelerates, even crusing at 100 in 5th, half throttle and it just accelerates to 120 easily all while off boost!

I am certainly very impressed with the NEO!

Unfortunately mines dropped cylinder 5 :( flaming mongrel!! Im not sure what caused it, had plenty of vacuum leak drama from the plenum in past year and an accidental overboost of 25psi in third, all cylinders 155-160 and number 5 is 60..goes upto 200 with some oil squirted in.

rebore and forgies n rings or drop a stocky? thoughts?

I thoughtyou sold your 33? You building another or same but different way? Id throw pistons and rods at it but all depends on your power goal and what you wish to do with it.

Yes and no, depends on your powergoal. You've got Matty spinning up 390kW on a dead stock motor and it also gets punished. I've sbeen how he drives it lol

So why spend thousands when a drop in NEO will cost you half the price of a basic engine rebuild?

Just my thought.

I have 2 mates that had 300rwkw 25's for the same time I did, one drivin like mine, the other PUNISHED. both of theirs were built motors from very well reputed workshops, and both of them are on their 3rd motor now. while mine was on it's second when I sold it

with these power figures its a lottery either way, so i'd just got another stocker personally.

car is dedicated E85, its a big decision, having thoughts of running a higher comp ratio of mid to high 9s, gt3076 with .63 rear internal, goal is driving on streets and drags with reducing lag and making it feel very punchy on the street. 300-320kw max

stocker- solid from factory but still old and 155av comps..

rebuild- new pistons/rings ( possibly forged) and have 180-200 comp = more grunt and earlier boost for the streets

much simpler to just drop stocker in though and maybe shave a bit off head, don't want to overcomplicate stuff

      Leak from Tokico BM50 Brake Master Cylinder

      By brillo · Posted

      Hi, SteveL Thank you very much for your reply, you seem to be the only person on the net who has come up with a definitive answer for which I am grateful. The "Leak" was more by way of wet bubbles when the pedal was depressed hard by a buddy while trying to gey a decent pedal when bleeding the system having fitted the rebuilt BM50 back in the car, which now makes perfect sense. A bit of a shame having just rebuilt my BM50, I did not touch the proportioning valve side of things, the BM50 was leaking from the primary piston seal and fluid was running down the the Brake booster hence the need to rebuild, I had never noticed any fluid leaking from that hole previously it only started when I refitted it to the car. The brake lines in the photo are "Kunifer" which is a Copper/Nickel alloy brake pipe, but are only the ones I use to bench bleed Master cylinders, they are perfectly legal to use on vehicles here in the UK, however the lines on the car are PVF coated steel. Thanks again for clearing this up for me, a purchase of a new BMC appears to be on the cards, I have been looking at various options in case my BM50 was not repairable and have looked at the HFM BM57 which I understand is manufactured in Australia.

      R33 GTST Steering Rack (49001-19U05) Rebuild?

      By Gantai · Posted

      Well the install is officially done. Filled with fluid and bled it today, but didn't get a chance to take it on a test drive. I'll throw some final pics of the lines and whatnot but you can definitely install a DMAX rack in an R33 with pretty minor mods. I think the only other thing I had to do that isn't documented here is grind a bit of the larger banjo fitting to get it to clear since the banjos are grouped much tighter on the DMAX rack. Also the dust boots from a R33 do not fit either fyi, so if you end up doing this install for whatever reason you'll need to grab those too. One caveat with buying the S15 dust boots however is that the clamps are too small to fit on the R33 inner tie rod since they're much thicker so keep the old clamps around. The boots also twist a bit when adjusting toe but it's not a big deal. No issues or leaks so far, steering feels good and it looks like there's a bit more lock now than I had before. Getting an alignment on Saturday so I'll see how it feels then but seems like it'll be good to go

      Leak from Tokico BM50 Brake Master Cylinder

      By SteveL · Posted

      I don't get in here much anymore but I can help you with this.   The hole is a vent (air relief) for the brake proportioning valve, which is built into the master cylinder.    The bad news is that if brake fluid is leaking from that hole then it's getting past the proportioning valve seals.   The really bad news is that no spare parts are available for the proportioning valve either from Nissan or after market.     It's a bit of a PITA getting the proportioning valve out of the master cylinder body anyway but, fortunately, leaks from that area are rare in my experience. BTW, if those are copper (as such) brake lines you should get rid of them.    Bundy (steel) tube is a far better choice (and legal  in Australia - if that's where you are).
