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?

2.8 for sure man. theres not even a question in that. haha Plus the fact u get to keep your engine numbers all matching, no need to screw around with the rta and all that crap.

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.

      Has my R32 Climate Control Unit met its demise?

      Yes, I mentioned it in my first that I did everything that is mentioned online (Redo dry solders, clean connector between PCB's, etc.) and unfortunately it didn't solve it.  It crapped out again earlier today, so I replaced it. I'll keep the old one around to repair it at some point.

      I've looked at some oval stuff but still deciding what material to use for the back half to the muffler.   Yeah I do all my own stuff with ecu setup and have it sorted before generally paying someone (my old work) to do base runs and a few power runs then I'll do anything else myself at track or after review data. It's hard to find  a dyno owner these days that will hire out to random.

      Injectors are told by the ECU to open for certain amounts of time. If the injector flows more fuel, but the ECU doesn't know this, and is told to open for the same amount of time as the stock, smaller injector, then the larger injector will flow too much fuel/more fuel than the engine/ecu is expecting. You absolutely need an ECU to control injectors. You don't need a tune for a fuel pump (because your fuel pressure should remain the same assuming the regulator works). You don't need a tune for an exhaust (the parameters for fuel and air going into the motor have not changed much) You don't need a tune for an Intercooler (the parameters for fuel and air going into the motor have not changed much, it's just the air is cooler) Yes, forum regulars, I know that you really should get a tune for an Exhaust, and Intercooler. These *will* affect the tune, but the stock tune does have some leniency to it with stock AFM and Injectors. Intercooler and Exhaust will fit within this wiggle room. So will running a boost tee to about 10psi, which is a very old way of increasing boost which is not worth doing in 2024. The ECU is vital. It runs the whole show. Most people change injectors and ECU at the same time for this reason. Some people load base maps on some ECU's that have ballpark figures for injector sizing. Sometimes injector manufacturers are really great and tell you what parameters to input into your ECU, which is something you can do with your new shiny ECU. For a beginner, this may enable you to drive to the tuner to have an expert do the rest. Otherwise, you're installing injectors and ECU at home, and paying for a tow to a dyno. Or, you take the car to a workshop (be happy to travel across Melb for the right shop) and someone who knows RB will be able to source/provide/install injectors and tune the car at the same time if they have a dyno or access to a dyno. The reason so many people DIY things here is because finding said workshop is hard, expensive, potentially getting things wrong with miscommunication/other.

      @robbo_rb180 do you tune your cars yourself or do you send them to someone? If you do it yourself, do you hire a dyno, or tune it after logging it at the track? Meaning like touch ups when you tweak or modify something a bit
