Hey guys bought my first car not to long ago a 1995 R33 GTS4 which to be fair has a lot more power than my mums old corolla I used to drive, but after finishing off the sounds department of my car im starting to feel as though I want more from my engine. Ive got an RB25DE thats all stock and its at about 190,000k's. Ive considered getting a newer engine with lower k's but would this increase power or just life of the car? Is there a way I could slowly replace parts that would increase performance and increase its life? Any kind of information is helpful on a slight budget but willing to consider all :P

Cheers

I believe for a N/A car you need more than a slight budget.

Squeezing power out is a) expensive and b) you're not going to get alot from it. Money vs gain isn't great.

If you're dropping in another engine. Do you mean another rb25de?

If power is what you want then sell and get a gtst.

Haha ok slight budget is really irrellevant if Im honest. And as much as I know Turbo would give me more power easier id love to stick to N/A so checking out my options there. if it seems like id still be throwing money for no return then Ill look into turbo engine for my car or normal turbo skyline

190,000ks isnt really that much these engine can do quite allot of k's if looked after and regualry maintained, unless you're considering tracking the car i wouldnt bother paying for a new engine, though in regards to more power,

i would personally as stated above get a gtst etc More power less money trying to get big gains then doing internals etc on a NA

I'll be honest it is relieving to hear this.

Right so so far general consensus is get turbo car. Are there reasons to why youve both gone for the "buy turbo car" not "buy turbo engine"? I'm relatively new to the in's and outs of this so I wasn't sure

My R32 GTST had 225,000KM+ on the clock, solid as a mofo, bog stock @ 154rwkw on 12psi. Thing was an amazing car (for a p-plater).

My R33 GTS is a bloody slug. The best thing you can do with your N/As is to make them perform better, not get more power. Performing better isn't modifying anything to get more power out of it, it's maintaining what you already have to allow the engine to run better.

1. Change your spark plugs, make sure to gap the new ones to 0.8mm

2. Get new coils if you have to

3. Go for a drive in a dry day, drive until warm, drive home. Pop your head under the bonnet, under the car, etc. look for moisture patches. If you can take photos, do it and post it up.

4. Give the car a good, full service. Put an oil flush through and run two lots of oil through it. Take out the radiator and wash it out with a hose. Change the P/S fluid, bleed the brakes, put a K&N panel in (pod filters are horrible.. just don't do it), make sure you haven't got any cracked hoses or anything.

5. Go over your entire car and clean it out. Make a list of broken interior / exterior items, or even just things you want to change, save up money and change them.

6. You may need a new exhaust, make sure you get the catback + a new, hiflow cat.

7. Check your clutch + rear diff. Change if neccersary.

That's the best checklist to getting your N/A going better.

N/A's aren't for power... They're more for handling if anything.

Are you on your P-Plates? If you are, invest some money ina 5stud conversion, coil-overs, sway bars, strut braces, get a cool bit of camber going.

I'll let you know what this new mechanic says today, too.. we're going for a "test drive" to "see what's happening with my diff" and he should report back with some engine problems as well... if he's any good.

Awesome thanks man solid list to start through =] but just clarification then, N\A's are more just to keep goin and handle well then? whereas turbo is for the fast thrill?

Got my Full Licence, currently an ex Aussie in New Zealand but theres no more further licensing for me.

That would be good to hear of if he reports back id love to hear it, my dif has played up before and its stopped me giving it some round corners at the moment.

Fair enough. As a mini side question then. In Australia where do you buy your cars? do you go through dealers or importers or through auction sites? I got mine of trademe (essentially an auction site in NZ). Ive heard stories importers were cheap, but never found a site with solid facts

No worries mate

There's no real "n/a is for this, +t is for that", it's just that Nissan created the N/A as the base model you bought for cheap, and the +t as a semi sports model. Because they share the same suspension setup, handling is almost identical.

Because the N/A hasn't got much power, it's lacking heaps in the performance department, but makes up for it a bit in the handling department. You'll have way more fun in a turbo, but you can get your kicks in an N/A with corners and things.

I've got my N/A atm... I'll be swapping the engine out with an RB25DET and tuning it for 290rwkw. New gearbox as well. I was going to go crazy with her, but I've gotten to the point where I'd prefer a car that performs well, instead of a car that puts out heaps of power.

People buy their cars from all over the place. I suppose it depends on te criteria you're lookin at and if you can afford importing a car and getting it complied.

Also majorly depends where the best deal is to be had.

I bought mine from a importer. But did not import personally.

Look for a deal :)

Importers aren't too cheap. Better to buy domestic from a private seller around Aus. I got mine through a shonky dealer which was okay because he got it from police auctions or some shit i reckon..

Have had to fix a lot with my car.

Edit: sorry, I should say "importers aren't always the cheapest".

Yea i agree with the above i found majority of cases cheaper to buy privately specially if you know what to look for, i got my 4door gtst stock as a rock from a old couple for 6k , also as above its cheaper to buy a gtst

even a nicely modified one then to replace the engine for a det specially if you get a mechanic to do it for you, people do it dont get me wrong just all about how much coin you really wanna spend and how much hassel you can deal with.

Ahh so its sort of budget and what you prefer as to what you get?

ha well I believe I have some thinking to do as to which road I take, have always loved the practicality of the 4 door, but that may have to go :P

PS what kind of PSI do the stock RB25DET's run at?

And is it more expensive to run and maintain a turbo?

Just trying to make the right decision :P

My RB20DET ran 7psi stock, but it was pushed to 12... any higher and shit would break.

It's more expensive if you mistreat her. Take care of your car, and you won't be spending heaps on maintenance.

Here's something to make your thoughts even harder: 4 door GTR... go fourth and ponder.

Yea excactly ive always been partial to 4 doors :) There are heaps of r33 4door gtst kicking around for sale though they are usually little cheaper as allot of people prefer the coupes :)

7psi from factory if i remember dont quote me on that lol.

And to answer you're other question well its just another thing to go wrong i guess lol worst could happen is you're turbo gives out but stock replacements are easy to find and the stock ones do last awhile they can handle upto around 12psi if remember safely.

I havent found it more expensive so far compared to my old r33 na i had previously i mean i guess ive spent more on mods because theres more options etc but not in terms of maintence just do regular oil changes with good grade oil and dont go nuts on upping the boost :)

Treat you're car like you would treat a good women and she'll look after you :)

Is that a normal stock turbo PSI or do they change significantly depending on model make and manufacturer? Ha I like to test my car out so to say but always make sure its well looked after.

It was a brief ponder before i heard a yelp from my wallet, still soemthing to look into though I do suppose

You sir have a fine way with words. Well that would be a better option to look for i reckon :P Yer I get the idea of a coupe but i like to cart people and my bike around :P

Oh thats allright I cant imagine Id be trying to push a max PSI out of it, Id keep it close to how it was made =] But with the oil this leads to another question, what do you guys use? last time I did a change I believe it was 10-40 semi synthetic? is there a certain type I should be using?

Its cheaper to get a car that was original with a turbo because its always been there and didnt cost anything extra in the first place and turbos are common now so i see them on car sales cheaper than NA's.

Its a GTS-4 so you will have to get a stagea RB25 or an RB26 if you want to fit it easily. The RWD engine fits but it needs a bit of work done to fit it. It will cost you a few thousand to do this, especialy with a RB26. You might be a few weeks without a car aswell if it matters.

Also, my engine gave way at 160,000km. It was using 5L of oil (40w-70) every 500km to keep it going. It's a GTS-4 and work at NISSAN and it took me 6 months to get all the parts and i was doing the fastest orders and stuff availible, a lot of engine stuff for the NA is not available anymore so i has to get 40thou genuine pistons and ACL bearings, new genuine crankshaft and heaps more bits and it was a headace to find the stuff. Cost me thousands and after the rebuild i got 20kW out of a newer fresher bigger engine, it was not worth it. I have always thought rb25's to be fragile as f**k, but i cant say that its a fault because they get thrashed. Just dont bother with a NA engine you get no where if you dont have LOTS of money to spend on it.

    • Well, in 2007 he must have been charging about $1800 an hour. He only looked at the car for 5 minutes. And another 4 to write the report wrong, and another minute to correct it. Mind you, this was for a car that was: Stock engine, fmic (hole in drivers guard), all alloy intake and custom air box, 3 inch turbo back exhaust, lowered, and a set of 17" Advans (255/40/17 rear and 235/45/17 front). It was nothing crazy. The blue slipper wanted the "hole in the guard" engineered. But that was because he got the shits that I wouldn't "relocate the battery from the boot, back to the factory position in the engine bay"... In an R33 GTST...     Also for emissions, E85, and don't go wild on timing. It's amazing how the closer you get ignition timing towards max torque, the last couple of degrees really throw NOx counts right up. And for the huge increase in emissions, it's only a small increase in torque.
    • He'll be looking down and swearing about "the damn apprentice" for trying to convince Duncan to use percussive maintenance... 😛  
    • I swear at my GKTech ones every time I have to take them apart and replace a spherical. But I wouldn't swap them for anything else. They absolutely slay every other option, at least in terms of how they actually work. You sure you don't want to live with bearings? I mean, they don't have "ball bearings". They are rod ends and sphericals throughout. Tough as nuts, even though I have found more than one way to wear them out.
    • From when I was looking at getting the 86 engineered for the turbo, the joint said to put in a few euro 5 or 6 cats, then tune the car on a nice clean E85 tune When I was looking at a turbo for the MX5, it was basically the same thing, a couple of cats and a nice clean tune Although, it will depend on the year of the Jeep IRT emmisions standards required, and what mods are done, especially if it has a newer engine installed that requires a higher Euro
    • Yeah - but it's not actually that easy. There are limits for HC, CO, NOx and particulates. Particulates shouldn't be a concern in any petrol engine unless trying to comply to the very latest Euro standard. But getting a tune right so that all the others stay within limits AT THE SAME TIME is not a trivial exercise. You couldn't possibly get it right by just guessing at the tuner's dyno, unless he had a 4 gas analyser up the pipe, which is not often the case these days. It used to be. Every decent shop that did "tune ups" (as opposed to tuning) would have a 4 gas analsyer. Perhaps there's still quite a few of them around these days. But most "tuners" are only watching O2 and power readings.
