Brad's Mad032 Rb26/30 Build

[shnaped_second]

A few people keep asking how the car is coming along so i thought i might do a build thread on it. I bought the 32 late 2012 as a half finished project, it originaly was a 1989 gts4 but had a forged rb26 thrown in it and made rwd only. When i first got the car it needed a few things done as it was sitting around for a couple of years and the whole inside of the fuel tank had rusted and needed a good clean/flush out, new fuel pumps. I had it tuned at Next up performance in brissy and it made 460rwhp on 18pound. That sort of power was pretty fun and wasnt too laggy with a gt3582.

This arrangment lasted for nearly a year then i spun a bearing when i was taking my missus for her first drive so i had to scare her, the oil pump didnt fail but it either didnt supply enough oil or the custom sump which was made for it wasnt designed to well. From there ive had the motor taken out and decided to go a 3ltr. I spoke to rips and Lewis engines in regards to a 3ltr and Rob from rips said it would be a 2-3 month wait for a motor and after speaking to Darren i decided to go with his torque monster bottom end and his ultimate 26 head. Its still yet to be finished but with 280 deg cams, 12mm lift and the rest in there she should make some decent power.

My turbo choice was made from watching 34GeeTeeTee's results and listening to what Lithium had to say about the forced performance range of turbo's and wanting to try somthing different that hasnt been done, well not that i have seen on a 26/30. I was looking at the HTA3794 but they had the super 94 on sale which is "like a 3794 hit the gym" as fp say on there website. I also bought a 60mm turbosmart powergate as i previously had a 48mm progate and couldnt fault it. Last for the hotside i bought another 6Boost manifold to suit the 26/30 with t4 divided flange and 60mm gate And will be going full 4" exhaust when its put back together.

From there ive bought some other bits a pieces, I bought a N1 bar with the lip from nissan for just over $700 delivered and I was chasing a set of 33 gtr wheels and i was quoted from Nissan $1700 plus gst each (lol) so I got a second hand set of wheels and had them painted and machined up at magit wheels on the gold coast, they turned out unreal and wrapped them in achilles 123's. Then i purchased some r34 gtt calipers and had them painted red and fitted with ebc pads, dba slotted rotors and HEL braided brake lines. See how these work otherwise some AP's or brembo's will be on the list.

I just recieved this plenum from rips and the quality of their work is unreal, so nice just to look at. Few other things i have is HEL braided abs delete kit and clutch line, Koyo 53mm type r radiator to keep it cool. Ive ordered a 5ltr surge tank from Aftermarket Industries running two walbro 460 pumps and a walbro 255 pickup but they said thats still a couple of weeks away. There will always be more but thats all i can think of for now.

Sounds balls Brad. Should be great fun. Interested to see how the big precision goes on a 30 bottom end. What power range do they quote it as having?

Are you going to convert it back to AWD or leave it as is?

All the best, look forward to seeing how it comes together.

Thanks mate, its a forced performance turbo and they have run into the 8's and over 900rwhp, im going to leave it rwd as I think frying 3rd and 4th gear is more fun

Picked up my cam covers today, painted in brembo gold to replace the shity chipped gold that was on there

Heres a pic of the brakes fitted but with standard rotors

[Lithium]

Haha good idea, have been trying not to annoy the hell out of you but this is very close to my "ideal" engine spec for a nuts road/track/drag GTR build - those cams are pretty nuts though!

Can't wait to see how this comes out, its going to be a monster.

[Lithium]

How did you decide on the cam size - they are actually seriously huge, you might need a bigger turbo

[shnaped_second]

Haha yeah they are pretty big, its what Darren supplies in that head setup

I'm interested! Looks like it will be an animal.

[Lithium]

Interesting, looks epic- looks like its expecting to be used with a more traditional "big power" style setup, like who cares about down low torque.... lets put a huge turbo on and rev the shite out of it The hope I had for the Super 94 is you won't need to, but that is definitely way more than sufficient to find the limits of the turbo haha.

This is going to be very interesting, indeed.

[R377]

Looking forward to seeing results with that HTA turbo.....

What size A/R turbine housing? You want low back pressure with those awesome cams, 12mm lift is getting up there, valve springs will have a hard time. Wicked!

When I ordered the turbo it said ar 1.15 but cast on the housing it says 1.14, either way I think it will flow enough at that size especially with 4" exhaust and 60mm screamer

what max rpm are you targeting? i see the bottom end is rated to 7500rpm.

7500rpm for now, plans to go 3.4 or 3.2 nitto stroker down the track

[black bnr32]

interesting.

what about engine management strategy and hardware?

thanks for posting and keep us updated!

No worries, im running a power fc with 2 x z32's, splitfire coils, 800cc injectors but will be upgrading to bosch 2200. Im thinking of just running the motor in on this setup the changing to haltech for e85 and lots of boost

[Lithium]

Not sure how the Splitfires will get on with E85 on a setup like that - not that I have tested it, but mates who have run anything like that tend to have upgraded to something a bit more lightning spec.

She's definitely quite a different engine combination. Those massive cams may end up making the turbo look a bit laggier than it could be - but I suspect it could still prove to be a bit of a monster, even though the Super94 is more meant to be a thing which uses boost rather than outright flow at lower boost levels to make its power.

Very much looking forward to seeing how this comes out!

There was some miss communication between me and Darren, he's put his 272 cams in not the 280, I thought it was that whole setup he used for the head but its not so I guess the 272 will work alot better on the 3ltr, motor isnt finished yet but is still coming along
