I have an R32 GTR with power fc and N1 Turbos (brand new) exedy clutch, sard injectors etc. Stock internals. My N1 oil pump blew and sent all its bits and peices through my engine and scored my piston walls. Which means I have no choice but to rebuild. So I was given 2 options for fixing it.

a) Bore it out to 2.8 with rods and pistons - plus a complete rebiuld changing all bearings, gaskets (tomie), piston rings etc.

Total cost: about $3000

b) An engine swap from an Autotech stagia with 80,000ks on it.

Total cost: Free (under warranty).

What I use the car for:

I drive in busy traffic from the hills district to Regents Park every day for work. Some weekend travel also.

So, any recomendations or advice would be great especially from those who have or have had forgies.

Cheers guys!

do a) as i cant even buy the parts (crank rod pistons) for $3000, thats a 8k -10k package. let me know who can do it for that as i will buy a couple of internal kits off them.

Its that cheap because its mostly covered under warranty. The 3k isn't entirely the issue its the 'everyday driving' and econonomy and reliability factors are my main concern. I am not really the sort of person that gives the car bootfulls all the time, I am more of a cruiser so I don't really care about huge power gains and stuff.

If it's only going to cost you 3k for a built 2.8.. then I'd be going for that..

Ok, I understand that I am getting a bargain with this rebuild package. I am very fortunate and well looked after but I really need to know if it will still be suitable for an everyday driver. Keeping in mind that I take excellent care with my cars by constantly maintaining them, warming them up and cooling them down and not going past 1/4 throttle for the first 15 minutes of driving (yes I am slightly obsessive). How long would a forged engine last? Does it get over heating problems? For instance when I drive home from work on a 40 degree day stuck in traffic for an hour.

go the 3k 2.8L, there is no replacement for displacement.

No replacament for displacement..? So should I save up and put a 350 chev in it? (Thats a joke...sarcasm was used, i will not be putting a 350 chev in it)

Didnt he say "bore it out to 2.8 with rods and pistons" not "get 2.8 with rods, pistons and stroker crank" and since you cant get to 2.8 with a bore alone i'm guessing he's not getting 2.8 unless he's already running the 2.8 crank. Jez is that the case?

Yes this is the case. He never mentioned a crank. He just said pistons and rods but for a 2.8 litre. Unfortuneately for everyone on here supporting the forged option (i think its actually everyone that has posted thus far) I have gone for the Autotech Engine (apparently identical to the R33 GTR). I get to keep my nismo injectors, N1 turbos, external oil cooler and my power FC.

My reasons to support this decision is because I am not a person who cares for monster power and I would prefer my car to be as stock as possible for daily commuting **dodges rotten tomatoes thrown at me**.

Your crackin it arnt you mate, I cant stand people like you.

Any normal half brained guy would choose a 2.8 over a stock R33 engine. ESPECIALLY if your only going to nanna the car, if your not going to DRIVE it SELL IT! GTRs are ment to be driven hard, grow a pair and Dont bullshit on forums mate, seriously....Annoying

3k for 2.8 kit is impossible. The crank alone will cost more than that.... Then you have pistons, rods and the build. So unless someone is willing to take up the cost for the rest I think its just a dream.

It would normally cost alot more than 3 grand. Most of the costs are covered by my warranty (labour etc). I think I am only paying for the parts which they get at a very good price.

Thanks sir for your excellent opinion. In five years and accross a hanful of cars I have blown 4 diffs, 3 gear boxes, 2 blown motors (well now 3). Most of my initial breakages were from driving a car like it was stolen. I used to flat change my first car at 13,000rpm on a daily basis (I was 16). Times have changed and I haven't lost my cahunes, I have just become more mature and responsible with my driving. Not to say that I dont give my car a boot every now and then for a bit of fun, like when you hit the motorway you try to find out how fast you can hit 100 ks from 30.

I would go the 2.8litre because you know the condition it will be in just built with strong internals, I assume forged pistons et cetera and you have the option of getting a lot more power in the future if you choose to (with less $$$).

Unless your very short on money right now :)

Even better, I'll pay you 4K and you can have my R33 RB26 and I'll take the 2.8litre built engine :ninja:

Ignore that other poster, SAU encourages real men/women on these forums who take it to the track/DECA for real speed :)

dude, he is selling you a pipe dream. all he's going to do is bore out the engine and fit some 88mm pistons and call it a 2.8. all it is really is a weaker 2.6. there is no way you can safely bore an RB26 out to 2.8 litre. a "proper" 2.8 involves a stroker crank, you increase the STROKE to get the added displacement (this also changes the bore/stroke ratio which changes the nature of the engine making it more 'torquey' less 'peaky'). all you're getting for your $3000 and 'warranty money' is you currently stuffed engine bored out as far as possible with some cheap forged pistons thrown in. it may still be a good deal IF and it's a big if, it's built properly. given they are making no money on it I personally have my doubts. my advice would be ask for a comprehensive list of what exactly is going into this $3000 forged 2.8 litre engine and what bore size etc? are they re-using your scored block? questions like that.

      Fake ARP bolts?

      By GTSBoy · Posted

      Well, maybe not. The main feature of Chinese manufacture seems to be incredibly variable quality, coupled with an apparent willingness to find a way to see even the stuff that fails QC. So the military could still take the cream of the production run and somehow sell the "sellable but not really useable" stuff to the stupid round eyes on the other side of the world.

      Have you adjusted the clutch pedal rod? You can wind it in to shorten it. Just can be a cnut to get to.

      Fake ARP bolts?

      By TurboTapin · Posted

      Yes sir, that was me. Fake ARP's are also a thing over here in Canada and we only order from reputable dealers. It's sad that even simple things like bolts and hoses are now also being copied... anything to make a dollar.  Story time. Like all cheap crap from China, it's even an issue with firearms. Roughly 15 years ago, I purchased a new cheap Norinco 12g shotgun. First time out in the bush with it, while firing, bolt assembly didn't lock and it fired out of battery. The receiver also being cheap steel, basically exploded in my face. I was lucky to be wearing eye protection. Long story short, don't buy Chinese junk. Also Norinco being state run and their only military arms producer, if ever they do try and take over a country, don't worry about it lol.

      Nismo copper mix twin “pull” pedal height engagement

      By ck_chino · Posted

      Installed  Nismo coppermix twin competition spec last year in my bnr32 with pull trans with Oem slave cylinder. The point at where the clutch disengages/enages is right at the top of the clutch pedal, meaning I barely have to push the pedal down for the clutch to be disengaged.  You guys that have the same combo are you experiencing this high pedal bite point??   Secondly I’d like to have the disengagement point lower meaning I have to push the pedal more(further not effort)for it to be disengaged.  I’m thinking to use a Nismo big operating cylinder(bigger bore at 13/16 vs Oem 3/4) which will require more pedal stroke to get the equivalent movement at the clutch fork. But I see Nismo web site says not to mix these 2 as the Nismo big operating cylinder doesn’t have enough stroke to disengage??? Any folks run both the coppermix twin pull with Nismo cylinder??    Thanks in advance for the replies but prefer only guys with pull clutches to respond. thanks
