Ok, I see it in writing, but any more conclusive proof than that? I'm not disputing it, just I've never heard of this before and I'd say if it were true early 26 blocks would be sought after for rebuilds which to my knowledge they aren't. From what I can read it's only a few people saying "yeah, they're better" If a tuning house/Nissan came out with that info, I'd beleive it

And to play you at your own game from the same links you posted...

"Though that rumors are spread quite often on the internet no one has actually come forward with any hard proof that these "homologation" blocks existed in production skylines. I have it on good authority though that the N1 block is certainly different from a september/89 build gtr. If rumors are true only the first 500 bnr32's were supposed to have these better casting blocks."

this is true

however ive done enough research to know that in either case, the strength of the block is nowhere near as important as getting a balanced long nose crank with a decent harmonic balancer, H beam forged conrods and forged pistons. i quite like the nitto kit but tbh its overkill for what i will ever use it for

-D

Its all very well for you pseudo mechanics to sit back on the forum and make estimates as to what my engine can and cannot do

I happen to have the estimates confirmed by road and track as well as the guy whos making the turbo

the compression test indicates all cylinders are within 10psi of each other, and having paid as much attention to the rb26 performance thread as you Andrew, I know for a fact that 300kw is not pushing a set of N1's by an stretch of the imagination

i for one will trust the advice of the very mechanic that has worked on the car for the last 3 years, rather than a bunch of armchair tuners who never even looked underneath the hood

incidentally, i have the first series of rb26's from the nissan factory. my vin no is 3129/89. The block is as known to be as strong as an N1.

Theres no f**king way Im going to blow a f**king piston thru the f**king side of the f**king block, and you know why? Cos i spend the f**king money on f**king tuning and never let anything run lean.... case f**king closed....

You guys are like a bunch of italian grandmothers trying to stop their granddaughters from getting some dick in em

-D

Ben you need to calm down or go somewhere else to play.

On your statements of mechanical knowledge, where you putting me in that group as well??

I was involved in engine reconditioning for more than 3/4 of your life and can no doubt teach your boys at Road & Track a few things..........I'll grant you that they would have me in the tuning department.

A block's thickness is totally indicative to a rod spinning a shell or a land cracking......you can blow engines in a bad way without an inspection hole in the side to show for it.

If as you said, your valve timing has been out for a year or 2 and you've hammered it like I've seen thru the Adelaide Hills, your pistons are probably itching to let go as we speak.

Anyway, calm down.....we're only talking car shit between friends.

Spot on, questionable running that sort of boost/power through a motor that has been running incorrectly for god knows how many kilometers of it's life. All we're saying it be careful, if it's a daily, don't run it on knifes edge, you still need to get to work should shit hit the fan

Im quite calm pete, maybe step back for a minute and realize that every post i put down isnt about you.

i know your history, i know u know engines, but to say you can teach a man older than you whos been building engines before you yourself had hair on your nuts its pretty rich. i think u need to step back and take a deep breath.

For your information, I never hammered my car in the hills or otherwise. I dont drive as hard as half of the heroes out there. I dont know whats so abhorrent that I can admit im not a hardcore driver and then everyone assumes i dont do my research. Fact is, I respect my car too much to push it so hard that it gets damaged. Thats why I've spent over $25,000 on the car over the last 3 years. Does that not count as to nursing the fk out of a car?

I really dont know what point you're trying to make. You've totally lost me.

And if anyone thinks I'm running anything on knifes edge simply does not appreciate the dialogue I maintain with my tuner.

Yes the valve timing was out, however it was within a safe tolerance and was running rich to a factor of 11:1 - which is hardly a ratio to worry about

-D

you don't go above 3500rpm ???? are you driving a diesel??? or your nanna to doctors ???

the N1's power curve will move up the RPM range ,making it less then fun in traffic, have you ever driven a honda VTEC below the 4k, like being chained to a house..lol no torque off boost

Ben not saying it won't be fun but after living with a partial tube frame race car on the street for 11 years..... it wears on you, RX7 with 300hp 12a Bridgeport/ alloy flywheel = electric motor , hauled ass but a bit much for a daily. wish I had it now...damn it..lol

and ben running too rich can kill and engine over time too, carbon build up= misfire from hot spots of carbon, broken ring when it dislodges, Pete is trying to say the same as me "think before you waste a buttload of money on a daily driver timebomb"

Just playing devils advocate here... just because you are running proper AFR's, doesn't mean you aren't stressing the engine. I can run my 26 with good AFR's, whack 24 psi though it then hold on. However, it won't last too long either

Guys

We're talking about n1's

they have the same f**king compression wheel as an r33 gtr and and a slightly bigger exhaust turbine than the ceramic version that still fits the 0.48 housing, and it just happens to be metal, meaning u can boost it over 14 psi

these are not rs turbos let alone -5's or high mount single ball busters

farks sake theyre equivalent to -7 2860's

next thing you'll be trying to convince me that the bogeyman is real

and yes mate, i keep the car under 3500 rpm when im driving in traffic, i hardly think accelerating up a dudes arse and then slamming on th brakes is anything to be proud of, and I have a straight pipe exhaust so i try like hell to keep it as quiet as possible

-D

Meaning you are cramming a measurable more amount of air+fuel down the motors throat, resulting in more power, more stresses and increased wear.

Just saying s'all :)

word man, but geez, ive been reading the rb26 thread on sau for the last 5 yrs man, and i know for a fact that 300kw is not like asking a politician to be honest

they generally benchmark 290 for -7's / n1's on stock 444 injectors and afms. unlike many others, ive done the supporting mods before i got the turbos. i got the nistune. i got the injectors. i got the nismo calibrated afms. soon as i get the turbos themselves, i bolt them up and let shaun at boostworx go nuts

i have full confidence in road and track and boostworx. ive been using r&t for 6 yrs and theyve never made a single mistake, ever. cant say that about any other workshop ive been to.

Is that what your tuner told you?

Your valve timing should never be out, your crank & cams are either in sync or they're not...........what's this safe tolerance business??

Your ignition timing can vary and be within a safe tolerance however.

You can run an overly rich motor (which is also bad) but advance the shit out of your ignition timing and still get a high knock count..........why didn't your boys pick the TDC alignment issue up a year ago?

No disrespect to your tuners Ben, but even a 60 year old mechanic that's been assembling engines since Noah was a boy may not have the same machining or diagnostic experience as maybe a 35 year old with 20 years of engine reconditioning experience.....they each have their own speacial talents and could no doubt teach each other new tricks of the trade.

By the way, I'm only a smidge over 35 :)

cant reply to u technically to u pete because im am a lowly pc technician who obviously knows f**k all about engines

and if ur that shit hot at machining then i want you to machine my fkn engine in 2012.

put it this way, im getting the power back at LOWER boost than was required before

ultimately i cant say how its going to go either way, however im getting a full rb26gasket kit, removing me intake plenum and manifolds, rocker covers etc

getting everything powdercoated black except for manifolds which are geting ceramic coated along with the exhaust housing of the new n1's i get next week

i cant see how any damage can be caused for any tune where there is too much fuel. lack of power sure. not like im melting my damn pistons

-D

EDIT - You're under 35? Yeah and I rooted alyssa milano last week. really.

I'm def not and no thanks

Where did I say I was under 35

:) = far from it, LOL

aww

i was hopin u would machine my cylinders

and i could get soem big boobed bitchen to rub u on the head like a buddha statue, for good luck

but hey, if ur too busy to let women rub ur head then bugger ya, do what ya want, etc

-D

as far as im concerned, if its good enuff for charlie, its good enuff for me

I understand everything you are saying Ben, but for R&T to say your motor will be fine with the upgraded power level on the basis of a leak-down test is pretty poor. You have only had the car for 3 of its 20 years, so god only knows what maintenance schedule was had before you got it. Unless they have opened the engine and inspected the internal components I just can't understand how they can guarantee you are not going to spin a bearing, crack a ring-land or whatever else.

But it sounds like you are on the right path putting in all new gaskets etc,, so at least they can have a partial visual inspection of your engine internal before the N1s go on.

And on the topic of you 'going easy on while it' while it was mechanically impaired (just in case you forgot), you gave the 32 a fair hiding on the way to Kadina last year and Balgowan also - I saw more than a fair plume of black smoke behind you and you will remember being destroyed by an n/a V35 at one point :) .... which I now understand now you have revealed your power level issues.

    • Decided to upgrade my pressurised plastic coolant expansion tank for a fancy pants alloy version The OEM versions can get brittle, even the new plastic one I got when I first got the car is a starting to show signs of "stress" I wasn't cheap, but it is basically unbreakable
    • Morning all, I have an RB25DET Neo that's in need of a rebuild. Will need new pistons etc due to detonation damage. Would anyone be able to recommend a shop in Southeast Queensland who I could bring my long motor to for a rebuild? Just want someone who knows RBs and whos built a bunch of them before. TLDR - recommended engine shops for RB rebuild.
    • Gday Thought it was about time I started a build thread! As expected this project has snowballed into a huge financial liability, but unless you’re strong willed and responsible, it’s not a surprise. Background -  My first turbo car was an R32 GTS-4, got my full license and then totalled my Au Falcon a week later, so while trying to sell my RMZ450 dirtbike to buy another car a bloke offered to swap the R32 which at the time I felt like I was ripped off but looking back and seeing prices of those now ($40kish) it was a good deal, I didn’t know enough about these cars to appreciate what I had so sold it before the RB20 blew up. Between here and there, out of 12 cars I’ve owned the note worthy ones are a V8 Lexus SC400 (soarer), a couple of XR6 Turbos and my beloved S15 which I had for about 3 years, picked it up for $12500, repairable write off but she was fine, gun metal grey/pewter and bone stock/unmolested until I got my hands on it. Ended up spending about the value of the car and 280kw, 2 demerit points by the time I got defected and sold it for $14500 (also $40kish in today’s market, rip) Fast forward to the present day, I’m in a much better position financially and daily an MQ Triton (great cars, pipe down Ranger Bois), I cruised marketplace and car sales for a few months looking for another R32, the best deal I could find was an absolute rust bucket half finished project for $12000, until this R33 popped up in Port Macquarie for $18k - unregistered and barely running but decent shape, kept an eye on it for a few weeks and the price steadily dropped, $16k then $15k then $14k, that was the point where I was like shit someone’s gonna snatch this up! It was owned by a young bloke who had big plans but him and his missus just had a baby so smartest move financially for them but big gain for me. So 2 days later I’m towing a car trailer to pick this thing up. Roughly 2 weeks and $3500 later I’m cruising around Newcastle in my beat up R33 all smiles and dose noises! It only needed some basic shit to get it going, coil packs and air flow meter, electrical stuff and all fluids changed, 158k kms and running pretty good, nice smooth engine after oil and coolant flush - when I say coolant I mean it had been filled up with tap water, every gallery and heater element was filled with rust, 8-9 flushes later and still had brown liquid coming out but she’ll be right. The car was painted R34 Bayside Blue at some point but whether it was a cheap job or just not looked after is anyone’s guess, clear coat flaking like sausage roll.  Was rethinking my choices and contemplating life, had it up for sale for $22k - still cheaper than any registered R33 but got little interest, next minute I had an opportunity at work - 6 months overseas for good money, so that was a no brainer, fast forward again and here we are with a 50% finished project. Current Mods - 200ish KW according to butt dyno Was tuned with Apexi PowerFC EBC (old school Greddy Profec)  Stock turbo (more shaft play than a Tinder date gone right) 3inch turbo back Varex muffler  Aftermarket injectors of mystery size, Power FC showed 36% duty cycle at full boost so not behd good size Someone had good intentions but stuck with the stock R33 MAF so we had misfires at 6000rpm due to the MAF hitting 5.2V So far I’ve redone the entire interior with carpet form Car Mats Direct, new Seats and steering wheel from Autotechnica, also sound system by Autobarn (mainly Kicker) Also MCA pro comfort coil overs - Hands down best purchase yet, worlds of improvement over the tired 30yrold shocks Goals - 450kw/600hp on flex tune New paint job - Midnight Purple 2 Engine is at the shop getting rebuilt with forged rods a pistons, new valves and springs, ATI Harmonic balancer, Aeroflow 7.5L sump, rear head drain and oil restrictors as per oil control thread* and cam covers modded for larger breathers, other stuff I can’t recall of the top of my head Parts purchased and to be installed once the engine is done -  Engine loom from Wiring Specialties including these options: Haltech Nexus S3 R35 Coil pack conversion  PRP Dual Trigger kit Fan controller  Other Parts -  262 Kelford Cams Turbo - Hypergear ATR43SS3-ProS with T51R mod (whistly boi) 6 boost manifold (high mount) 50mm Turbosmart Pro gate (plumbed back for legal reasons) HKS Super Turbo Exhaust with High Flow Cat Custom 3.5inch dump and front pipe 1500cc Bosch injectors  Fuel Pump walbro 525 Haltech MAP and IAT sensors Haltech Flex Sensor Fenix Radiator with dual thermo fans LS1 Alternator Kit Oil Filter Relocation from EFI solutions and Cooling pro oil cooler Many other things sitting in my garage waiting for that engine to come back. Progress pics to follow -  
    • Losses have to be less with DC coupling. Provided the battery inverter has decent MPP tracking ability - which really shouldn't be a problem. It's not 2005 any more.
    • Hi, Will the R33 GTR rear brake backing plates fit a GTST? I'm struggling to find GTST ones but can find new GTR ones.   Thanks.
