I thought that if it is anything other than a factory upgrade then it had to go over the pits. (rb25de from gts-x in a r32)

This is how i read the papers but if im wrong please correct me as ill be doing a simillar thing.

Cheers

Ross

I got a yellow sticker (kind of unrelated..) just after I put the 30 in, went of the pits, they checked engine number, notarised it, and I was on my way with a legal RB30 under the bonnet :P

As long as you don't have a bigass highmount turbo there should be no dramas and I'm pretty sure RB25 falls inside the capacity increasement zone.. with my 50% increase I was afraid they were going to make me get engineering certificates.

cheaper to engineer all at once though

Point being for certain engine upgrades you won't need engineering.

My RB30, even though it's a full litre increase (50%) they didn't deem to need engineering. Most likely because it looked factory and with only an RB25 turbo on there it wasn't insane, similar to stock response but just with a shitload of nuts down low.

I believe in taking things in steps instead of rocking up to the pits with a 50% larger engine with a 600hp turbo hanging off the side and then hoping it's going to get engineered and passed. I have the engine installed and licensed, when I go to get it legal after the GT35R goes on then the whole 50% more capacity is a problem I won't have to deal with.

i went from a 3L NA to 3L turbo (2j)

they didnt pay any attention to the high mount and just took the engine number and engineering cert

i know yours is a 50% increase but as long as they sign it off

i dont think it matters much which way goes first

other thing is, if you want to save money

pass with the rb25 or 30

then legalise it when u get a yellow? (if ever)

I was planning on doing it all properly but got a sticker like 3 days after the 30 went in so I just had to hope that when I went over the pits they didn't decide to have a baby cow over it :)

Steve, did you get your tailshaft made at Final Drive? when I got mine done, Phil was telling me how he had recently made one for a guy that put a 2jz in his 32..

Hah yeah, plenty of cars kicking about with that sort of power and a few coming out with a LOT more..

I almost feel like I'm being a pussy shooting for 400rwhp to start with :) but really, that should be plenty in a rwd 32 platform!

You WILL NEED AN ENGINEERS CERT!! the mark up is not 25%. I am current running around with a rb25 that isnt yet ticked off with vic roads as they wont allow it without a cert. I have been to vicroads over 5 times, each time with more evidence that the r32 came out with a rb25. Last 2 times i went they even cought up on it being a rb25de that came with the r32.

vicroads people also wont care less if its got a high mount turbo as big as the engine or a stock turbo, thats not why that knock you back. The last chick who looked for the engine number wouldnt have known what a turbo was. i have a high mount and that hasnt been the problem. So far, everytime i have gone, they have somehow noticed the engine size step up when typing on their computers so a message must come up saying it needs an engineers cert.

sorry to put a down on your plans but seriously, its not easy getting it passed. im ganna try a few more times at a different vicroads in the hope someone just doesnt pick up on it. Might be easier for you being in W.A but in victoria, it seems im ganna have to fork out like 4G to get this all cleared over :D

Yes mate different state.....

Bubbas living proof that he doesnt need it

kermits ceffy also has a rb25 which originally was a rb20 (also in WA)

i went from NA to Turbo and strapped on a high mount

engineer cert would cost 500$ give or take a hundred depending on what you want engineered

emissions testing, db test, brake test would all be under $500

WA has it good? lol

    • Had a go at the stuck crush tube this afternoon. Tried things like grips and a chain wrench first but wouldn't just twist straight off. So got to work with a drill. Started small and kept a depth stop on to make sure I didn't drill into the bolt. Made a line of drill holes all the way up and enlarged them. Then a combination of chisel and Dremel to split it all the way up. Levered the split to get oil in there and eventually it gave a bit while levering. Worked it back and forth with loads more oil till it was spinning freely, then with grips I could work it downwards and off. And no significant damage to the bolt (not by me anyway - just the 27 years of rust)
    • Well, I'm tired. I'm tired because about 4PM yesterday, before today's appointment someone immediately bought my bumper. They couldn't get it any other day as they're on the way back to NSW. So I had to do that big GTR conversion I had been planning. Unfortunately, the information on SAU about what you need and how this is done is incomplete. So what should be a simple bolt on affair, yeah, it's not. Did you know if you use all GTR items the bonnet won't close? This little manuever sent me into about 1am the night before trying to dodge a way to get it closed. I will have to revisit this in the next few days  - or maybe not, I may let a body shop figure it out. It all needs to come up and my motivation to pull the bumper off is low. It also seems to hit things in the bay where the GTT bonnet didn't. Yes I used 100% new OEM GTR items. Today, I had the joy of driving to the dyno looking like this: Given I had roughed in the fuel and given sensible but pretty conservative timing, I didn't really bet on having the car drive out any real difference than when it drove in. Sadly due to a miscommunication and laptop fun and games (and almost bricking the dongle, prayers and firmware updates indeed), I ended up using HP Tuner credits to licence the car that was already licenced. So in the end my laptop was used. It turns out my butt dyno is still well calibrated after all this time. The 325kw was on 74% Ethanol, the 313kw line was on 98. The other line is the 'before' line which was 281kw. While the numbers are pretty low, they're pretty in line with what you'd expect. Even if US dynos bump the whole result up about 50KW, gaining 10-15% is similar gains.  The curve of the cam is pretty much spot on with what was discussed as well. All this said, it still feels bad to not see the number you secretly want to see. Even if the car drove great beforehand, and I knew pretty confidently the car would drive out much the same way it drove in due to the nature of a wellish dialled in LS1 not gaining much if anything at all from being tuned from where it was. As expected, the car isn't particularly sensitive to running it at anywhere between 12.0 and 13.0 - And the initial timing at 20deg and 12.0 made 308KW. So 3 degrees of timing, and leaning it out to 12.7 for 5kw, anything above stopped giving any benefit until E85 (which has an additional 2 deg as before). Car itself behaved entirely fine. I found out that 100C = 1.15V! IAT at about 7pm was 19C. I might mess with the bonnet mounting.. but given the REO NEEDS TO BE CHOPPED TO FIT A GTR BAR this is possibly something I may leave gathering (more) dust until it returns to paint jail.
    • It sounds farrrrrrr too cold at your place Duncan... Here I was thinking our 10 degrees overnight is getting cold...
