we got sks package and then i pinched the tops off the teins and used them since they were spherical bearing, not rubber.

Before we changed to SK's deal, we put softer springs on the teins, and i must admit that helped a little bit but it was still stiff...which led me to believe that the shocks were still crap in terms of their valving, from them to the SK's was a massive improvement all round. Had to play with spring rates abit, but nothing too major. However the aussie spec ones seem to be loads better over the jap ones.

We are way off topic here, talking suspension in rb30 country.

A question for the guys that have been driving around with the RB30 hybrid motors....

Have you had any problems with the bottom end strength ??

I have been told by 2 experienced RB26 mechanics (one worked in Japan for Nissan) that the RB30 bottom end wont handle high boost and is the weak link. I'm not sure if this is just because they are RB26 biased or if its in fact true...

It wont stop my build, i'm just curious.

lol; no. Which has reminded me; its time to update it. :)

The blokes are Boostworx are top blokes; always done the right thing by me from the start so its well deserved.

There's so so many workshops out there that simply do not give a sh*t.

ok guys i need help im only a newbie....

i am currently rebuilding the rb30/25 to put into a lh torana 4 door.

i have read the first 86 pages in the last 2 days and i just need to ask one thing...

i am going to buy a rb25de engine for the head and bolt on acc, though can i use the non turbo loom in a turbo application with a power fc?? or should i lok at buying a rb25det wiring/loom for ease and better use.......

HELP!!

I am 90% sure you will need a turbo loom due to the knock sensors.

you may be better off looking for a power FC first and buying the correct loom for it.

it really depends on wich RB25DE head you are using 33 or 32.

if it was me I would buy a R32 re25de and use an R32 rb20det loom with an ap engineering pfc.

the loom and ECU will dictate wich CAS, ignighter and injectors you can run, once again in my opinion the r32 loom will be better as you can run top feed injectors.

Those of you with GTR's and or using GTR looms.

The knock sensors.

The GTR knock sensors don't screw in to the RB30 block as the thread dia of the GTR's bolt is too small.

What have you done/easiest way to sort the issue?

Brass piece chopped off and then drill/tap that brass piece to suit the GTR knock sensor bolt?

Or isn't there enough meat/difference in thread size to do such a thing?

i was goin to use a r33 rb25de engine for the conversion, tho im waying up weither to just buy a rb26dett head??

the only thing is price...

i was going to use the rb25de head with rb25det springs and maintain the vvt...

even though i get the de loom with the engine i will probably just hunt down a rb25det r33 loom or can i use the r32 rb20det loom???

cubes, i havent got to the knock sensores yet though what do u think would be the best approach as u have done it all....

thanks guys!!!

the bosses are there - on mine anyway - you just have to drill and tap them. the GTROC thread where R32 Combat / Andy shows his rebuild has good pics.

cheers champ.

Just a question before i buy it, am i able to use a rb25de NEO head??

    • Even more fun, leave all the ADAS stuff plugged in, but in different locations, hopefully avoid any codes!   And honestly, all these new cars with their weird electronics. Pull all the electronics out Duncan, and just shove an aftermarket ECU and if needed a trans controller in, along with a PDM. Make it run basic but race car styled!
    • To follow up a question from earlier too since I had the front bar off again (fking!) This is what is between the bumper and the drivers side wheel And this is the navigator side, only one thing but its a biggy! So basically....no putting coolers in the wheel arches without a lot of moving other stuff. Assuming I move to properly race prepping this car I'll take that job on and see how the computers respond to removing a whole bunch of ADAS modules
    • So I prepped the car for another track day on Wednesday (will be interesting to see coolant temps post flushing out and the larger reservoir, with a forecast of 3-14 being 20o cooler than last time I took it out). Couple of things to mention; since I am just driving the car and not taking a support vehicle, I took the rear seats out and just loaded the back up Team Trackday style. Look at all that space! To cover off removing the rear seat....it is weird (note the hybrid is probably different because it wouldn't have folding rear seats) Basically, you remove the lower seat base, very similar to a r series but it is a clip that pulls forward to release the base rather than it being bolted down. Easy Then, you need to remove the side section of the rear seat on each side. There is a 14mm head nut at the bottom of the side piece, the it slides upwards off a hook at the top to release; you also need to unhook the seatbelt from the loop at the top. Then the centre piece is weird. You need to release/fold the seats forward with the tab in the boot on each side From there, there are 2,x12mm headed bolts holding the rear of each seat to the folding bracket, under the trim between the rear seat and the boot (4x christmas tree clips there, they suck). The seat is out but you can see where the bolts attach to the bracket
    • As discussed in the previous post, the bushes in the 110 needed replacing. I took this opportunity to replace the castor bushes, the front lower control arm, lower the car and get the alignment dialled in with new tyres. I took it down to Alignment Motorsports on the GC to get this work done and also get more out of the Shockworks as I felt like I wasn't getting the full use out of them.  To cut a very long story short, it ended up being the case the passenger side castor arm wouldn't accept the brand new bush as the sleeve had worn badly enough to the point you could push the new bush in by hand and completely through. Trying a pair of TRD bushes didn't fix the issue either (I had originally gone with Hardrace bushes). We needed to urgently source another castor arm, and thankfully this was sourced and the guys at the shop worked on my car until 7pm on a Saturday to get everything done. The car rides a lot nicer now with the suspension dialled in properly. Lowered the car a little as well to suit the lower profile front tyres, and just bring the car down generally. Eternally thankful for the guys down at the shop to get the car sorted, we both pulled big favours from our contacts to get it done on the Saturday.  Also plugged in the new Stedi foglights into the S15, and even from a quick test in the garage I'm keen to see how they look out on the road. I had some concerns about the length of the LED body and whether it'd fit in the foglight housing but it's fine.  I've got a small window coming up next month where I'll likely get a little paint work done on the 110 to remove the rear wing, add a boot wing and roof wing, get the side skirt fixed up and colour match the little panel on the tail lights so that I can install some badges that I've kept in storage. I'm also tempted to put in a new pair of headlights on the 110.  Until then, here's some more pictures from Easter this year. 
    • I would put a fuel pressure gauge between the filter and the fuel rail, see if it's maintaining good fuel pressure at idle going up to the point when it stalls. Do you see any strange behavior in commanded fuel leading up to the point when it stalls? You might have to start going through the service manual and doing a long list of sensor tests if it's not the fuel system for whatever reason.
