Hey guys, i've been seriously thinking about my current situation with my r33 gts-t, and have come to a conclusion with 2 options in mind:

1) Go all out and aim for 250-300rwkw from my r33 25t

2) or sell my car, get a a-b car, and save up for an r32 gtr (eventually getting one within 6mnth period)

Ive been searching topics and what have you all day finding out about r32 gtr's and the whole import issue, and will end up just buying a well look after one from here (NZ), if i take the gtr route that is.

My goal is to have a streetable daily driven skyline, but one thing for sure is once i start modding i wont stop heheh, so thought beforehand to ask you guys which route you'd take, im willing to save up for an r32 gtr if need be.

My r33 atm has the following mods:

3" exhaust + split dump

Apexi pod

Hybrid fmic

thats about it, and a set of 18" wheels

the car has done 165000kms, but hasn't given me any grief since day one!, but then again it's never been modded, would you guys think about going all out on such an old engine?or is this still nothing.

If i was to take the gtr route, i would probably keep it stock for the year, and maybe just save up for future mods, and keep cash bottled up in case of rebuild...but im hoping to not get a lemon lol.

One thing with the 32's, when in standard form, are they quite a reliable car to drive everyday?, as i knw the r33 has been nothing but great in my past 3 years with it, hasnt ever had problems (only light mods though...). I say this because i was thinking maybe the first year with the gtr i'd prolly go for more looks, then move onto power later on......i.e wheels/suspension.

Sorry if i've rambled on for so long, im just not thinking right atm!

keep the 33.

you've got no mods on the thing yet.

probably got close to stock power.

that's why it's so reliable. and will stay so.

you wanna go all out for close to 300rwkw and reliable?

just buy the bits required on the stock internals.

when it pops, get a RB30 bottom end and bolt it all on to that.

cost you piss all and will make the power you want reliably, at lower psi and at lower revs.. with more torque.

if you buy an R32 GTR and spend say $5K to do things that SHOULD be done...

new turbo's

exhaaust

ecu

intake

tuning

compression test etc..

then that will last a long itme too.

but you wanna go all out, it will be a money pit..

your choice.. 300rwkw can be had from your current car with much less money than doing up a gtr from scratch.

how strong is the rb30 bottom end man, and how much can they be had/fitted for, what usually causes the bottom end of a stock 25t to give in? and is it worth dropping compression on the motor or not.

I think a compression/leakdown test from my current motor will help, how much do these costs?

i still am deciding, but either way im sure i'll be happy.

you say more torque down low? you mean it could be more of a practical street car if done right?

i'd keep the 33.

the main thing that makes the bottom ends go on rb25's is leaning out of your mixtures then one of your pistons go pop.. like so:

PIC01406.jpg

but other than that, ive seen stock internal 25's make 300kw+

Cool thanks for that, im just thinking about all that power and how well the gtst will cope with it, as i'd really like to do some track work aswell, im think a 1-2way lsd would definitely help, as would better tyres...i'd probably deal with it as i go.

How about the brakes on a 25-t, anyone ever upgraded after making big hp?, i'd think they would do the job as they're quite beefy from the factory.

stock rb30 bottom end from a series 2 VL non turbo.. there are a couple of people making good power.

guy on here used a series 2 VL rb30 bottom end (with over 300,000kms on it) stuck a stock RB25 head with upgraded valve springs, GT3540 turbo, external wastegate, 16 psi boost and made 306rwkw.

that's one good example.

SK has built a few in his time.

one of his has now got over 70,000kms making 450hp.

RB30 bottom end can be had for about $100.

put in new rings and genuine bearings, your current oil pump, new water pump, new tensioners and new timing belt.

you current head will bolt on to it with no problems.

you will need to work out a way to get oil to the head for the VVT to work.

there is a great DIY guide put together by user on here CUBES.

there is a link to it in his signature file.

yes it will be heaps more streetable at 300rwkw compared to the rb25 at same power.

Brakes - cheapest way to get more braking power would be some DBA slotted cross drilled discs, new Feroddo brake pads, Motul dot 5 or higher if available brake fluid, and a brake master brace.

or you can go all out and get some big brembo's and suitable discs.

LSD and suspension will all help with traction.

do a search in the appropriate section on sau.. there is a braking and suspension section .

cheers, how much would a workshop charge to do a rb30 bottom end to my 25t???

It sounds like a good plan of attack, can the factory bits bolt onto the bottom end so i can leave everything stock atm and work on it later on???or is it best to do a conversion with everything else (larger turbo ec...)

And what needs to be changed/strenthen at the same time mate as i'm goijg to do my sau search research on the subject now lol

cheers

Personally, I'd get a 32 GTR.

It's such a better car than an R33 GTST (performance aspects.)

If you spend 5k on a GTR? It will be an absolute weapon and if you managed to purchase a good clean GTR, then you won't have any problems, they are pretty strong in every aspect. Also, with the AWD you will be able to get the most use of your power. Handling? Let's not go there.

I'd only keep the GTST, if i was having difficulty selling it.

Peace.

Well, before you buy the car make sure u get it inspected by a peformance mechanic, especially check the engine via compression/leak down tests. Also check the body for rust. 4.5k for a standard rebuild sounds about right.

If all goes well, you should be alright. Besides alot of them have already had rebuilds. I'd keep spare money though, because if somethign does break it will be costly, engine and turbos inclusive. But if you decide to get one, you'll never look back.

thanks, im still deciding, have so much on my mind right now, but with gtr's how many km's should i be looking for....somewhere below the 100,000km mark???

and would i be better off not importing and getting one from here in New Zealand.

BTW how much do leakdown/compression tests cost?

Im assuming if i look hard enough i'll be able to find a clean r32 gtr, non 89 import for around the 23k mark???

Yup.

Well when i got my car tested, the mechanic charged me $150 to test the car completely, including compression/leakdown.

23k....yeah you could get a clean 89/90 model for that much. Also, don't be fussed about kms, lot of the cars are wound back anyway, u should be worried about condition. So if a car has 80,000kms but a crap engine, bad body and worn interior and another has about 120,000kms on the clock, but a healthy engine, straight body and nice interior, you'd obviously go the second car.

cool thanks, what else did he check for $150 that seems like a good price, was it a friend mechanic, sorry ive never done one b4

Yeah friend mechanic.

Everything. He took about 2 hours.

He even described the paint in detail etc.

    • Well, that's kinda the point. The calipers might interfere with the inside of the barrels 16" rims are only about 14" inside the barrels, which is ~350mm, and 334mm rotors only leave about 8mm outboard for the caliper before you get to 350, And.... that;s not gunna be enough. If the rims have a larger ID than that, you might sneak it in. I'd be putting a measuring stick inside the wheel and eyeballing the extra required for the caliper outboard of the rotor before committing to bolting it all on.
    • OK, so again it has been a bit of a break but it was around researching what had been done since I didn't have access to Neil's records and not everything is obvious without pulling stuff apart. Happily the guy who assembled the engine had kept reasonable records, so we now know the final spec is: Bottom end: Standard block and crank Ross 86.5mm forgies, 9:1 compression Spool forged rods Standard main bolts Oil pump Spool billet gears in standard housing Aeroflow extended and baffled sump Head Freshly rebuilt standard head with new 80lb valve springs Mild porting/port match Head oil feed restrictor VCT disabled Tighe 805C reground cams (255 duration, 8.93 lift)  Adjustable cam gears on inlet/exhaust Standard head bolts, gasket not confirmed but assumed MLS External 555cc Nismo injectors Z32 AFM Bosch 023 Intank fuel pump Garret 2871 (factory housings and manifold) Hypertune FFP plenum with standard throttle   Time to book in a trip to Unigroup
    • I forgot about my shiny new plates!
    • Well, apparently they do fit, however this wont be a problem if not because the car will be stationary while i do the suspension work. I was just going to use the 16's to roll the old girl around if I needed to. I just need to get the E90 back on the road first. Yes! I'm a believer! 🙌 So, I contacted them because the site kinda sucks and I was really confused about what I'd need. They put together a package for me and because I was spraying all the seat surfaces and not doing spot fixes I decided not to send them a headrest to colour match, I just used their colour on file (and it was spot on).  I got some heavy duty cleaner, 1L of colour, a small bottle of dye hardener and a small bottle of the dye top coat. I also got a spray gun as I needed a larger nozzle than the gun I had and it was only $40 extra. From memory the total was ~$450 ish. Its not cheap but the result is awesome. They did add repair bits and pieces to the quote originally and the cost came down significantly when I said I didn't need any repair products. I did it over a weekend. The only issues I had were my own; I forgot to mix the hardener into the dye two coats but I had enough dye for 2 more coats with the hardener. I also just used up all the dye because why not and i rushed the last coat which gave me some runs. Thankfully the runs are under the headrests. The gun pattern wasn't great, very round and would have been better if it was a line. It made it a little tricky to get consistent coverage and I think having done the extra coats probably helped conceal any coverage issues. I contacted them again a few months later so I could get our X5 done (who the f**k thought white leather was a good idea for a family car?!) and they said they had some training to do in Sydney and I could get a reduced rate on the leather fix in the X5 if I let them demo their product on our car. So I agreed. When I took Bec in the E39 to pick it up, I showed them the job I'd done in my car and they were all (students included) really impressed. Note that they said the runs I created could be fixed easily at the time with a brush or an air compressor gun. So, now with the two cars done I can absolutely recommend Colourlock.  I'll take pics of both interiors and create a new thread.
    • Power is fed to the ECU when the ignition switch is switched to IGN, at terminal 58. That same wire also connects to the ECCS relay to provide both the coil power and the contact side. When the ECU sees power at 58 it switches 16 to earth, which pulls the ECCS relay on, which feeds main power into the ECU and also to a bunch of other things. None of this is directly involved in the fuel pump - it just has to happen first. The ECU will pull terminal 18 to earth when it wants the fuel pump to run. This allows the fuel pump relay to pull in, which switches power on into the rest of the fuel pump control equipment. The fuel pump control regulator is controlled from terminal 104 on the ECU and is switched high or low depending on whether the ECU thinks the pump needs to run high or low. (I don't know which way around that is, and it really doesn't matter right now). The fuel pump control reg is really just a resistor that controls how the power through the pump goes to earth. Either straight to earth, or via the resistor. This part doesn't matter much to us today. The power to the fuel pump relay comes from one of the switched wires from the IGN switch and fusebox that is not shown off to the left of this page. That power runs the fuel pump relay coil and a number of other engine peripherals. Those peripherals don't really matter. All that matters is that there should be power available at the relay when the key is in the right position. At least - I think it's switched. If it's not switched, then power will be there all the time. Either way, if you don't have power there when you need it (ie, key on) then it won't work. The input-output switching side of the relay gains its power from a line similar (but not the same as) the one that feeds the ECU. SO I presume that is switched. Again, if there is not power there when you need it, then you have to look upstream. And... the upshot of all that? There is no "ground" at the fuel pump relay. Where you say: and say that pin 1 Black/Pink is ground, that is not true. The ECU trigger is AF73, is black/pink, and is the "ground". When the ECU says it is. The Blue/White wire is the "constant" 12V to power the relay's coil. And when I say "constant", I mean it may well only be on when the key is on. As I said above. So, when the ECU says not to be running the pump (which is any time after about 3s of switching on, with no crank signal or engine speed yet), then you should see 12V at both 1 and 2. Because the 12V will be all the way up to the ECU terminal 18, waiting to be switched to ground. When the ECU switches the fuel pump on, then AF73 should go to ~0V, having been switched to ground and the voltage drop now occurring over the relay coil. 3 & 5 are easy. 5 is the other "constant" 12V, that may or may not be constant but will very much want to be there when the key is on. Same as above. 3 goes to the pump. There should never be 12V visible at 3 unless the relay is pulled in. As to where the immobiliser might have been spliced into all this.... It will either have to be on wire AF70 or AF71, whichever is most accessible near the alarm. Given that all those wires run from the engine bay fusebox or the ECU, via the driver's area to the rear of the car, it could really be either. AF70 will be the same colour from the appropriate fuse all the way to the pump. If it has been cut and is dangling, you should be able to see that  in that area somewhere. Same with AF71.   You really should be able to force the pump to run. Just jump 12V onto AF72 and it should go. That will prove that the pump itself is willing to go along with you when you sort out the upstream. You really should be able to force the fuel pump relay on. Just short AF73 to earth when the key is on. If the pump runs, then the relay is fine, and all the power up to both inputs on the relay is fine. If it doesn't run (and given that you checked the relay itself actually works) then one or both of AF70 and AF71 are not bringing power to the game.
