I also run a 5" one with 3" flanges. For the sake of an extra couple of dollars go with the 5", you want the least amount of restriction possible. The only problem I had with my Venom Cat is I had ordered it as direct bolt on with a bung to fit the standard temp probe. George said the standard fitting they use is a larger diameter than the Nissan fitting, so I paid extra (through George) for an adapter to space it down to the correct diameter. But as it turns out that didn't work as there was no internal base to seat the probe. So in the end I haven't been able to fit the probe and wasted money in the process.

The sound of this engine will be epic!

Guilt-Toy... there has been no mention of Wolf ECU's on this thread. My tuner raves about the Wolf V550 and I was wondering what your thoughts are on this ECU?

Yep same price... It's a quality piece of kit, so worth the money for sure.

No that is the mount for the R33... I gave them the measurements so they could modify that mount to suit the R32 (with the RB25DET gearbox) and they made it up for me. Now that they have the design my understanding was they were going to advertise it as a new model, though either way if you email them they will make one up for you. Just mention you want it the same as the one they made for Ryan (in Australia) back in March/April.

After getting plenty of motivation from the likes of Antz and $$slowmedown, I decided to jump on the band wagon with some VHT Wrinkle paint. I planned to do just my Nismo strut brace (as the paint was flaking off in places) but ended up also doing the windscreen wiper motor and the upper radiator supports... In other news the car has been re-tuned as it was starting to play up in the cold temps (with the tune we did in summer). The car definitely makes more power now, but weren't able to get a max power reading as there was a slight miss at around 5500 - 6000 rpm. It did make 260 rwkw at that point (with the power almost climbing vertically) so I'm guessing peak power is probably at least 280 rwkw. To fix the miss I've just changed to a colder plug (BCPR7ES) so we'll see how it goes. Also I've just purchased a GTR front bar and Reo (from RBMunkie) so when I can get it painted I'll put that on and work out if I'll have enough clearance to also purchase an ABFlug front diffuser.

We're just trying to help mate... The advise you have got would only make sense if you were building a race car, as the on/off throttle response is definitely better with short runners. However in that case a race engine doesn't need torque down low, as the revs are always kept high. Also don't confuse the throttle response you gain (due to the short runners and less intercooler piping) with increased turbo spooling. Your turbo will spool slower with short inlet runners as there is less torque down low and hence less exhaust gas to hit the turbo and help it build boost. All the advice you've had in this thread has been sound. If your car is a daily drive, loosing inlet runner length is just stupid, especially with the RB20. For me if you must go to a front facing plenum, your best two options are to either modify you current plenum to change the throttle body location or buy a Plazmaman style plenum top to retain your lower runners. Do I know what I'm talking about? I have a RB25 in my car and swapped the standard plenum to this when I went to a front mount intercooler.... Any gains I made in throttle response, were rubbish compared to the loss of torque down low and lower spool rate of the turbo. So after 5 years of persisting with this plenum and getting different tunes to try to improve the driveability, I went back to the standard lower runners with a MX performance plenum top. That lesson has wasted probably $2000 of my money.... We're not a performance shop trying to convince you to spend money, so we can profit from you.... We're trying to give you advice so you save money!

Footnah - That plenum is a copy of the Greddy plenum designed for RB25. Due to its short runners, you will be very disappointed with the loss of torque if you go with that plenum.

I agree with the comment above... in most cases going for a front facing plenum is going to be a performance loss, not a gain. This is due to the shorter runner length robbing you of torque low in the rev range. Due to the smaller capacity this will be very apparent with the RB20 engine and make it a pig for day to day driving. You can get cheap copies of the Plazmaman style plenum top on eBay, this will retain your lower runners which is probably the best compromise. http://www.ebay.com.au/itm/All-New-POLISHED-Nissan-R32-Skyline-RB20DET-RB20-GTS-Intake-Manifold-Plenum-/121040978566?pt=AU_Car_Parts_Accessories&hash=item1c2e9ac286

Is this going to be "fair weather drive only" when completed? After all this hard work, it's going to break your heart to get road grime all over it.

Awesome engine build! My R32 started out life with the RB25DE engine... I loved the sound and throttle response. I was very tempted to swap the bottom end for the RB30, but went down the boring (and more cost effective route) of an engine swap to a RB25DET. Will be very interested to see how you get on.

Are you selling the front bar, or lip only with the kit? Also, where are you located? Cheers

Arizona Z Car is your friend... I purchased the front brakes for my Skyline through them, and they fabricate some pretty awesome parts for the 240Z.

The cheapest way to fix your problem is as Dobz says above and go for a standard RB25 turbo. Though you'd be lucky to hit 200 rwkw. If you want to stick with the current turbo, you could go for a Mx Performance Exhuast manifold (with 1" runners) and external gate. I have done this with my HKS GT-RS turbo and it has transformed the power delivery. I have also heard of good results with the RB20 (full boost on a GT3076 at 3600rpm) with this manifold setup. Though if you went down this route, you wouldn't get much change out of $2000 once you have it installed and a custom dump made to suit. By limiting yourself to less than $1000, you don't really have much option other than the RB25 turbo.

How do the Eibach springs compare with the Whiteline springs that Gary used to bundle with his recommended setup for GTR's and GTSt's?

...sounds like we need a tutorial developed for how to do the kingpin replacement - I'm concerned about mine now How's the gearbox going Roy? My 20 box lasted for 22 years (with 6 years of that mated to a RB25 making around 240rwkw) and it wasn't until I went for mega torque with my GT-RS that it started making bad noises.

They look good... much better option than leaving them chrome - especially given you have a white car.

That's a great idea for checking boost leaks... I may have to make something similar, even if I don't find a leak it could be a fun weekend project. I take it that your blow off valve recirculates back into the system, as if you had a blow off valve venting to atmosphere I wouldn't have thought pressurising the system like this would be possible.

Someone has probably just purchased the Nismo Speedo and swapped it out with the 180kph speedo in the GTS cluster. I've done the same with a 280 kph speedo into my GTS cluster. See below...

Well done mate... What I love about your car is that it still looks awesome and doesn't look like a stripped down drag GTR. Your car is one of the best looking R32's on this forum, and it runs mid 8's... Unbelievable!

It's a modified Navara sender with the RB25 cog attached... The link below has some good info for the mod http://www.jdmlegion.com/KnowledgeBase/Engine%20and%20gearbox%20conversions/Making-a-mechanical-speedo-sender-for-the-RB25-gearbox-f0271b89-cd6e-425d-bc0a-ee62f51dfaa7

My Vibra-Technics custom gearbox mount has finally arrived! For those of you with a RB25 Gearbox in a R32, Vibra-Technics now have a modified design that fits perfectly, so get in touch with them rather than going with the dodgy option of a modified standard mount.

I like the look of the lip attached to your front bar... Any idea of the brand?

Exactly right... Anyone who has dabbled in Radio Controlled vehicles will back that up. In the last 5 years alone the radio controlled vehicle dynamic has completely changed. Electric motors deliver much more power than a petrol/nitro of equivalent weight. Modern Lipo batteries and brushless motors offer awesome performance, and the price of each in the last 5 years has plummeted. For me the biggest hurdle that the electric vehicle faces is not the range, but the time to charge. As if you need to conduct a long drive that will require a recharge on the way, the electric car is not an option. I can't see an electric car refuelling in 5 minutes (like we can with petrol) unless you swapped out the battery packs. And that isn't really viable.

I take it, that price doesn't include the front lip? Also do you know what is the difference between the Nismo and the N1 front bars?
