Hey guys,

My R33 GTST is up the shitter, i've been told it needs a rebuild

Piston no2 is supposedly has a fracture and is only at 40% compression ratio.

I'm looking at over $3K is that right??

Take of the head etc. maybe might have a bad injector aswell

Can anyone list me more horror stories i'm about to encounter in there aswell???

Now i'm sort of stuck with the do I get a standard set of pistons or go the forge ones.

I've been advised that WISECO are good for it and Tomei

HKS and all the other name brands are way out of th price range.

Everyone I know is telling me go the forge, because i'm in there anyway do it right and its about $500 more.

ANyone know of prices for these mentioned forges around Perth or best to import them direct??

Thanks

If you can't afford jap pistons stick with stock ones, i don't rate yank stuff like arias, wiseco etc, and a set of hks pistons if you get them from greenline are not that expensive and of a much better spec and quality than the yank stuff..

as for a rebuild, if you buy the pistons budget 2-3k, by the time you factor in labour to remove and put the motor back in, which should take about a day, maybe a day and a bit, to strip the motor down, check, inspect and then reasemble, measure, check, re measure, buy bearings, gaskets, head gasket etc it will come in around the 2-3k from most workshops at a guess..

2nd hand motor range between 2-3k plus installation cost

I'm also in the middle of considering a rebuild. Leakdown and compression test came out bad. Looking for forged pistons as well. You can checkout modyourcar for rough prices

Question is, who can build me a RB30 in perth :-)

actually, where to find a RB30 in perth?

It all depends on what you wanna spent or can spent. When my Gtr's bottom end went, i could just change the crankshaft and be done with it but instead i opted for pistons/rebore/metal gaskets...etc

I agree though that if you wanna put pistons, might as well put Tomei/HKS rather than the Arias. But if you are not gonna be pushin your car hard, then i reckon the Arias will do. As a Trader, i reckon you should shop around and keep asking places like C-red / Hyperdrive..etc.

just recently had mine rebuilt, cost nearly 6K plus forged pistons + head reco ect...

i was orignally going to go stock pistons, but i got CP forgies, because my engine builder recommend them and could source them for the same price as stockers

cool thanks for the replies. Damn its getting damn expensive the problem with the 2nd hand motor you don't know how thrashed that was before and I could be looking at the same problem 1yr down the track.

But crap $5-8K for rebuild oh damn.

I tried looking for Tomei and HKS forgies on greenline and nengun but none mentioned for a RB25 it only had SR20 or RB26. Can anyone point out a model number??

Buy a 3L bottom end ($100-150 complete with rods and pistons), slam your head on it, change the engine number to what you have already on the RB25 and bingo - torque monster engine.

Pretty sure cosworth make tomei pistons, and JE make HKS pistons - may be worth seeing if you can find them, or better still - see if you can source an RB26 crank, rods and pistons - you see them come up second hand from time to time when guys do stroker upgrades.

If you just want to swap your engine over, there is a guy here http://www.teamloveofdrift.com/driftwa/viewtopic.php?t=78

selling RB25 engine for $2200, swap it over, then sell some bits off your engine (such as the head) to make some money back.

Probably the cheapest option, but the least fun :P

I've rebuilt my engine. From memory, as far as minimum parts go your looking at:

*Pistons

*Complete Gasket Set

*Water Pump (always worth replacing when doing rebuild)

*Fluids, Filters

*Machine the block

*Tidy the head

*Labour

Optional parts included:

*Fuel pump (although not part of engine rebuild, probably the cause of the detonation that caused #2 to shat itself)

*Clutch (option while the engine is out, may need one anyway)

*More labour

Buget an easy $6K...

Sounds like ure making a sandwich there Steve. I dont think its that easy. Plus once u get locked into a serious rebuild the tendency is to push it as far as it will go.  :)

    • Hi, is the HKS  Tower Bar still available ? negotiable ? 🤔
    • From there, it is really just test and assemble. Plug the adapter cables from the unit into the back of the screen, then the other side to the car harness. Don't forget all the other plugs too! Run the cables behind the unit and screw it back into place (4 screws) and you should now have 3 cables to run from the top screen to the android unit. I ran them along the DS of the other AV units in the gap between their backets and the console, and used some corrugated tubing on the sharp edges of the bracket so the wires were safe. Plug the centre console and lower screen in temporarily and turn the car to ACC, the AV should fire up as normal. Hold the back button for 3 sec and Android should appear on the top screen. You need to set the input to Aux for audio (more on that later). I put the unit under the AC duct in the centre console, with the wifi antenna on top of the AC duct near the shifter, the bluetooth antenna on the AC duct under the centre console The GPS unit on top of the DS to AC duct; they all seem to work OK there are are out of the way. Neat cable routing is a pain. For the drive recorder I mounted it near the rear view mirror and run the cable in the headlining, across the a pillar and then down the inside of the a pillar seal to the DS lower dash. From there it goes across and to one USB input for the unit. The second USB input is attached to the ECUtec OBD dongle and the 3rd goes to the USB bulkhead connected I added in the centre console. This is how the centre console looks "tidied" up Note I didn't install the provided speaker, didn't use the 2.5mm IPod in line or the piggyback loom for the Ipod or change any DIP switches; they seem to only be required if you need to use the Ipod input rather than the AUX input. That's it, install done, I'll follow up with a separate post on how the unit works, but in summary it retains all factory functions and inputs (so I still use my phone to the car for calls), reverse still works like factory etc.
    • Place the new daughterboard in the case and mount it using the 3 small black rivets provided, and reconnect the 3 factory ribbon cables to the new board Then, use the 3 piggyback cables from the daughterboard into the factory board on top (there are stand offs in the case to keep them apart. and remember to reconnect the antenna and rear cover fan wires. 1 screw to hold the motherboard in place. Before closing the case, make a hole in the sticker covering a hole in the case and run the cable for the android unit into the plug there. The video forgot this step, so did I, so will you probably. Then redo the 4 screws on back, 2 each top and bottom, 3 each side and put the 2 brackets back on.....all ready to go and not that tricky really.      
    • Onto the android unit. You need to remove the top screen because there is a daughterboard to put inside the case. Each side vent pops out from clips; start at the bottom and carefully remove upwards (use a trim remover tool to avoid breaking anything). Then the lower screen and controls come out, 4 screws, a couple of clips (including 3 flimsy ones at the top) and 3 plugs on the rear. Then the upper screen, 4 screws and a bunch of plugs and she is out. From there, remove the mounting brackets (2 screws each), 4 screws on the rear, 2 screws top and bottom and 3 screws holding in the small plates on each side. When you remove the back cover (tight fit), watch out for the power cable for the fan, I removed it so I could put the back aside. The mainboard is held in by 1 screw in the middle, 1 aerial at the top and 3 ribbon cables. If you've ever done any laptop stuff the ribbon cables are OK to work with, just pop up the retainer and they slide out. If you are not familiar just grab a 12 year old from an iphone factory, they will know how it works The case should now look like this:
    • Switching the console was tricky. First there were 6 screws to remove, and also the little adapter loom and its screws had to come out. Also don't forget to remove the 2 screws holding the central locking receiver. Then there are 4 clips on either side....these were very tight in this case and needed careful persuading with a long flat screw driver....some force required but not enough to break them...this was probably the fiddliest part of the whole job. In my case I needed both the wiring loom and the central locking receiver module to swap across to the new one. That was it for the console, so "assembly is the reverse of disassembly"
