for big power the RB26 head is better. but you also need a new wiring loom and possibly ecu depending on what you go with.

i hope you have set aside 20k+ for the build.

yeah i was thinking the same but then i seen them built for $6000NZ here http://www.dodsonmotorsport.com/index.php?...l-products.html or i could get one for $6000aus from an unfinished project sale atleast i would have most of the work done i will most likey change a few things to make it stronger what do you think deal or rubbish?

call and ask them the price for that engine. there is no way you are going to get a forged bottom end, full turbo setup and dry sump for $6k NZ the parts alone are worth double that and then some.

for that kind of money expect a bare stock internal RB30DET long engine.

all the info i foun on prices for parts on that engine build were all atleast a few years old i figured the price might have dropped or they just didnt use the best parts but your probly right which sucks

IMHO -

- Read the SAU forums re the build.

- Speak to a mechanic who's built more than one, preferably many. Get a written/detailed quote.

- Chat at length with someone who is driving one and go for a ride.

- ask the owner the FULL cost. This will vary from the quote you get.

dollar for dollar, I reckon a street car is better off with the 25 head with VCT. You get the benefit of all that extra torque coming on progressively and earlier. And for a road registered street car you couldn't want for a better package. It's the way I was/will be going. with WMI and a forged unit and the right turbo you've got to be good for 350-450rwkw and thats healthy for a rwd.

while he already has a 25 head for 600+hp (which is what he seems to want) a 26 head is a far better starting point than a 25 head as you can fit much higher lift cams due to the solid lifters as opposed to spending lots of money to convert the 25 head to solid lifters.

by your sig you appear to have an RB25 head already. check out the RB30 sticky and see what power people are getting. a 25/30 will provide way more power than a rwd can handle so the extra cost of an RB26 head is not bang for $.

thanks ill take a look and i dont know how good my current motor is internally it has already been cooked badly once which is why im shopping for new engine rather then taking a chance on it and i thought it was better off starting with rb30det because either way i was gonna spend a lot forging it

i was thinking along similar line based on the info i have found on the net

    • Jump into the wasteland. Plenty of random posting/chatting going on in there.
    • I did not go to GTR Festival. It's quite a long drive and the car wasn't dialed in yet. I also wanted to see how the racing portion went before going. From what I can tell the classes were not heads up, index, or bracket - just whoever has the quickest ET wins. Never heard of that sort of thing before and maybe some people like it but it's not my cup of tea. I don't suspect I'll go if that is how the racing is done. I did get the car out three times and had issues each time. Some were my error - haven't raced the car in over two years - and others were parts. Had trouble getting the clutch to slip correctly and remembering how it was set up in the Haltech. Broke some drivetrain parts as well that couldn't be fixed in a couple days to get back out. Season definitely didn't end the way I wanted but at least the bearings are still fine! Not a fleck of material in the filter. Really hoping next year is the year I can actually test this car properly. 
    • find it funny everyone claims different fuel chains, do different things with their fuel blah blah blah. We don't have that many fuel terminals in Australia. The fuel tanker trucks drive into the terminal, fill up, and drive directly to the service station and dump out. The majority of fuel you get, is coming out of the same terminals. The variation is actually at the individual service stations and how good their tanks are, as well as how much turn over they actually have. Older fuel stations, that haven't had their tanks replaced are going to end up with the worst fuel. Also a lot of older stations have shit design, and shit maintenance, and end up with more water absorption into the tank. This is when you then get a bad batch of fuel. Other shit things happen, like tanker drivers have a f**k up, and starting to unload the wrong compartment on their truck into the wrong tank. 
    • Yeah go with that one 
    • This one?? In other news: I cannot tell the difference between my red MX5 with the silver grey hard top......... and the Ferrari 599XX EVO, they might as well be twins, well.......apart from the big wang hanging off the back of the Ferrari...🤔🤣, without the wing they are identical
