I wouldn't get too worried about those inferior engines Steve. A well built stroked RB is another level compare to those engines with their happy peak dyno numbers

Nothing for SA

How about a rb26 cam trigger kit?

I have a IQ3 logger dash and just use the GPS for speed. I believe if you need the odo then an rpm hall effect sensor on the wheel is needed.

Haltech recommended 220-VP-TURBORPM which has vnet module + sensor but the extra sensor won't be needed. I searched around and found these 2 v-net modules may work -230-VM-USM -230-VM-TURBO SPEED MODULE (USE WITH 800-SS-SPEED) Has anyone tried these?

Has anyone wired up the turbo speed sensor yet? I have a Racepak IQ3 dash and wonder if anyone know what module I will need for the turbo speed sensor. Thanks in advance

It's funny how the magical "500" number pop up. If it's good enough for the Japanese to accept the N1 for racing why isn't it good enough for time attack event I suspect those Evo weight are not quite the mass produced version either. I suspect some bias here. We will make it as low as possible and then add weight if we are under. Only WTAC requires minimum weight, the other events don't so I don't just build the car for that weight. It's not easy to get the GTR to below that any how but just in case. Not nice to see some unfairness of this magical 500 number. Does anyone know of any real reason for the "500"?

Yes those early Evo were very light. I think they quoted the wrong minimum weight for the R32 GTR. Nissan produced a number of N1 car with a curb weight of around 1400kg. Let me try to dig out some more info Ahhh Wikipedia it is http://en.wikipedia.org/wiki/Nissan_Skyline_GT-R: The Skyline GT-R 'N1' model, introduced on July 19, 1991, was designed for home-market N1 racing with a total of 228 units produced. The most notable change was in the engine, which was upgraded to the R32-N1 specification. The car was also lightened by the removal of the ABS, air conditioning, sound system, rear wiper, trunk carpet, and the use of light-weight headlights. No color options were available and all 'N1' cars were delivered with a thin layer of Crystal White paint. The result was a 30 kg weight savings for a curb weight of 1,400 kg.

Car was cut free from the jig last weekend. Time to put the racing carbon armour back on...

The car is in Vic, I am in Adelaide and I receive a lot of pictures of the build. A lot of the pictures are quite detail of the R&D and I have not ask what I can/can't share so I am just giving the builders some respect. I will share what I can a bit later on. I've got the same wing and would not mind seeing what you have done so I can install it onto my street R32 later down the track. I think I got the 8" upright though because that was what they had back then. Freddy will make me a dry carbon bonnet and a set of doors. Contact him if you want to loose some more weight mate

It will be ready. Most things are done. Just that I am not sure what I am allowed to post/share on here so I have been a bit "shy" with my thread and I have been so hectic with work. Looking forward to some testing soon. Did you use any boot reinforcement with the Aeromotion wing? Good luck with the project.

Awesome...more RB racers for the event! Yes it's Danh and I am in as well. Looking forward to catch up with you guys and good luck with the preparation

Awesome another R32 for WTAC Hope everything goes smoothly.

That's great news John. Another BNR32 in that class to challenge the sea of evo :-)

I am sorry I have been away for a conference. It sounds like the OEM upright has an inhertent weakness there. Do you have any pictures of where your previous upright broke Brad? Anyway I talked to Liam and he said he was planning to double sheered it anyway. They are trying to also design something stronger given your information. Please load up some picture of the previous broken upright Brad.

Much appreciate for the info Brad. The component used in this conversion is over engineered rather than under. Suspension arms are bigger than usual, 3/4 spherical not 1/2", bearing carrier etc etc. We have opted to go for spherical bearings over rod ends as the guys are not a fan of rod ends in bending, common but weak point in design. For time and cost saving, I've decided to use the oem upright which has very strong bearings. We even had an engineer to look at the bearing and had the a ok with him. The R35 use the same bearing. So I am confident with this. Riverside is a very reputable sport sedan and V8 Supercar builder so I have trust in them. The car is welded to a jig, suspension arms placement are carefully calculated from Suspension 3D software for optimal geometry and are built to last. I've not tried to skim on weight here. It's almost done. I have to give respect to Riverside and not post too much of their R&D up here. You know Liam, send him a message, he's happy to chat with you.

That's nice. With the T618Z I get 1 bar of boost at 3500 to 4000rpm but this is on a big 3L and big (laggier) cams on the street. I dont know what it is on the dyno. We have yet to run the car at such large boost though.

Modified front upright

That's a beautiful car White but this ex drag car is being made to go faster around corners.

A lot of work has been done in the past few months. I've been too busy to keep this thread alive (sorry). I will try to post more pictures probably later in the year. This will be the car new ride height Hoping to do some testing in a few months and a real shake down at WTAC this year.

Congrats mate. Really great to see the new result. Well done Matt!

Here is mine sub many years ago on pump fuel 98. Looks a bit laggier than your. This was done in 4th gear with the OS box (1.000 ratio) ...from memory. What gear was your done?

lol Sub Boy32. I see where you guys are coming from now. That was an unintentional slip on my fault but you well respected guys would of know that I was referring to the fact that most people usually mistakenly look at the top peak power number to rate turbo/engine. This peak number is a product of rpm as well. Hence my mention of rpm in my earlier post. Some would say that the VE of the rb head is not good for high rpm esp with the 3L. With the right cam and turbo setup, this is not the case. Yes peak torque is early but the drop off can be minimise enough that the peak power can still be achieve around 9krpm. My twin T618z still make power all the way to around 9krpm. Peak torque is earlier. I posted an old dynogaph of the car 98fuel many years ago. I think it was in Marko old RB30 topic. At around 20psi it made 600hp and the power was still climbing. Anyway I am a track guy, so torque and area under the curve are what I am really after. Peak number is jiberish to me really. This number talk was just to clarify my unintentional slip...which I am glad I see where you guys are coming from now LOL Sub does that means your 8374 is similar to my twin 618z? Could you post a dyno please? I will try to dig up my old post.

yes and I like engines with square bore:stroke ratio too
