hi buddy im planning to buy a r33 gts with blown engine, just wondering if i could drop in an rb26 without a mod plate as i've heard in South Australia you only have to fill out the form to change your engine number. Also do i have to register the car as turbo (i hope not)? for the brake upgrades can i go for gtst ones? or have to be brembos as stock r33 gtr?

Another option is to rebuild the engine as i've had the turbo kit with came with the car, i'm a bit confusing about turbo return oil/water as NA block doesnt seem to have them?

Just for stock RB26 I believe you can use r33 gtst brakes, but I wouldn't plan on power upgrades as people with RB25's put brembo's on

You only need to fill in change of engine form and on that form is asks you if you changed the brakes, rego is no different from 6cyl to 6cyl turbo

good info, what about that 100cc increase does it require a mod plate? and yes it's a stock engine with rebuilt N1 turbos 240rwkw, it looks pretty standard though dont think the cops will pick on it

save yourself the hassle and ring transport SA to find out the specifics. If they wanted to, a trip through the front of VIS to check numbers, then a full inspection where they could pick on anything and everything. Doing the minimum is asking for a reaming.

SA doesn't have mod plates the most legal you can make it is make sure its a stock RB26 and do the 5 stud conversion and gtst brakes

there is a rule somewhere that state x amount of HP increase needs x amount of stopping power

maybe give Rory Thompson a ring see what he can tell you

Pretty sure it will need to be inspected by TransportSA.

I put a RB25DET into my ex-RB20DET R32 and it had to go over the pits with an emmisions certificate and R33 brakes.

yeah but you increased capacity

i know a RB26 is increased capacity also, so you might have to ring about that one or call Rory then you wont get 3 different answers by 3 different people

capacity doesnt mean anything. If the car was sold with that motor ie the r33 came with the rb25 and rb26 motors, then it is legally acceptable to do so, as long as you have all the emission gear, ecu, and brakes as mentioned. Any engine swap must have a front pass through regency (number check of the new motor), then a pass out the back to make sure its all done right. Ring up Transport SA or Rory as Madaz said.

Same, put a 26 in my 32 and had to do the same thing to pass.

not all the time,most of the time they just want the new numbers on the form. as long as the engine isn't stolen and a variant of that model was released with that engine should be okay.

Ie droppped a 308 into the wifes Lh 6 cyl torana, just mentioned on the form that i upgraded to V8 booster/master and front discs and it all went thru with no inspections.

Pretty glad too, wanted to avoid Regency as much as possible, especially with the 9" rear end and excessively large cam fitted to the new motor :whistling:

      Thinking of getting a Q50 300hp and just tuning it instead of getting the Q50 Red or 400R

      By 180 wanabe · Posted

      So next year I am looking at upgrading from my VE SS bomadore ute to something more refined.  I wanted to stick with a V8 but not anything German or Australian, either a coupe or a sedan. So if I wanted anything newish that limited my options to either the Lexus RCF which I quite like. But with the price they demand and a kid on the way a 2 door coupe is probably not going to be the best idea. The next best thing would be the ISF but the newest models are 2014 and commanding over 60k and even the older 2008 models in ok condition starting around 35k is kind of bullshit. So I figured if I could not have the noise I could perhaps make do with easy power. Enter the infinity Q50 or Skyline equivalent. The price difference between the 300 and 400hp models seems a bit crazy. Right now there is 300hp Q50 one on carsales from a dealer with 61km for 27k drive away. If I wanted to get a 400hp Red or 400R car the prices seem to start at 43k From my limited research it seems that the only differences are that the 400r/Red Red runs more boost and a more aggressive tune. There are are turbine speed sensors on the turbos. Has 2 pumps for the water to air intercooler. Runs an engine oil cooler. I'm guessing that the exterior trims might look a little more sporty as well. I had a lazy look for upgrades to bridge the gap on z1motorsports They have kits that upgrade the water to air heat exchanger as well as the coolant pump which should give a non Red/400r better intercooling temps than the stock Red/400r. I added an engine oil cooler with a thermostat as well to try and make things as close as possible. Obviously the ECU is going to need a tickle. Having not done much in the way of research they also sell a ECU flashing tool with pre loaded tunes that are supposed to boost the non Red/400R by 100hp which adds 1k USD to the cost. The total cost of the parts @ the current time including shipping and taxes worked out to be $4350 AUD. Personally I would rather get the car tuned on a dyno which would probably add more cost Assuming the worst that you got a workshop to install the new parts I would guess no more than 5 hours would be required in the worst case @ 5 x $150 per hour = $750 So the total cost could be around $5100 So for easy number 5k + 27K = 32k I guess that would leave some change left over to swap out the open diff and fit a LSD Any thoughts?

      Blow Off Valve Is Causing Car To Stall!

      Right, not sure why I thought it to be a lean spike. It might be fixable with modern card-style hot film MAFs which have some design features to avoid counting reversion flow but I've never tried it myself.

      I'm only going to hassle you for posting links to images. It's against my policy to click links that could be some nasty payload. Sadly, you need to make 9 more posts before you can just stick the images directly in a post, unless @PranK sees this and bends the rule for you.
