Nismo 3.2ish

Come a long way mate , expensive learning curve but all done at last ?

Here is the run-in tune , going down later this month to finish it. thought I would post it and see if there will be much of a difference after the next tune . Do not expect much of a change , just a bit more . The results were emailed to me and I was not too happy when I compared the both Dyno runs , but the scaling was different for this tune. But the car runs better everywhere than the Dyno suggests. Need your bum in the seat to appreciate it. Paul was up last week and took it for a drive , well more like a 120Klm romp, blew 3/4 of a tank and he was reasonably impressed with the way the car runs now .

Didn't go for the fancy gear, getting the car going hard is expensive enough LOL , but I love a nice looking motor, your cars engine bay looks amazing , it's done right and I would love to have it, a little jealous LOL Had the first chance for a bit of a run this morning , the car drives better than the Dyno indicates , it is better from the moment you press the peddle from what it was. Looking at the 2 dynos Graphs the old tune looks better under 3850rpm but I can assure it doesn't drive better. Should be interesting to see how it goes with a little more boost when they do the touch up tune , I don't expect much, if any improvement under 3000 but it is already coming on at 3000 ish pretty hard and impressive up from there. Good streetable ride and a shatload of fun.

THANKS MATE , SOMETHING HAS GONE TITS UP

NO GO

Yeah Matt , end of the day it's what you want from your car. It's all fun but an expensive exercise ? Here is the latest Dyno , bit hard to compare because you need same scaling setup on the printout to compare BUT it drives better. As you can see it is hitting 24 psi and dropped off a little mid range but will be tuned again after some Klms have been clocked and a bit more boost added Having trouble downloading Dyno ?

But there are many blokes like myself that have spent much more then they would insure the car for anyway. If the market is saying you can get $100k for something you have paid $50k , good for you, thats what it is worth Just because you have n R34GTR doesn't mean you will get $100k for it, it has to be in pretty good condition inside and out to get that type of money and not flogged under the hood. I think they should take each car on it's merits and insure them based on the condition and type of car it is. I have a worked R34GTR that is just about new underneath from the radiator to the tail pipe, ALL mods are high quality, not thrashed and in good condition inside and out but I doubt they give a shit as they have probably been told from above to do what the company dictates, the end :(

I am similar, haven't even had a speeding ticket for a long long time, garaged, country town and in a safe area and this year it is up 16% Methinks they will keep doing this until they drive us elsewhere ????? They do not seem to understand that these cars are not just being trashed by boy racers (they can't afford them)and the prices are going through the roof when I first got the car I could have insured a new $150,000 GTR about the same price a $45,000 R34GTR through other companies:/

couple of tricky bends there for the first time doing it

Looks like you have got your finger out, about time , looking good ?

Looking forward to see how the 9180 1.05 runs on the 2.8 Lt with the Vcam Has the Vcam step 2 gone from 8.7 mm to a 9mm lift or did you mod it? They are taking mine to 272 both sides , should be interesting to see how smooth they run with the Vcam and the smaller 8374 / 1.05 and if it runs out of puff earlier

It’s ALIVE !

So it’s true how they made copper wire , a Scotsman and a Dutchman fighting over a penny

Yeah, priorities like food and shit can get in the way is it mandatory to be a tigh arse if your Dutch , I thought that was a Scottish thing?

If you haven’t got the time but you have some spare $$$$$$$$s lying around, take it to someone before it goes up in smoke , lol hope you work it out ?

Had a test run in the RX8 , thought they had a hive of bees under the hood Did you have to do to the motor and what supporting mods to get this result ? I would imagine you blew a few donks trying to get it right and I bet it cost a bit on R&D to get the motor to perform for 2 years without going POP! Hope you didn't kill too many drivers to get the end result LOL

It really gets going ,? 13B is such a small motor and it weighs less than half of the RB26 motor 9180 on that, MAD , how do they stand up to high revs under that power?

just found and old thread, some interesting thoughts on grouting the block https://www.sau.com.au/forums/topic/354935-max-power-for-rb26-block/?page=2 Guess there are plenty more, for and against.

Like everything, there seems to be different options on grout fill, some do it if the car runs over 400awkw to absorb a bit of the twist I guess , read where some do it because of the harmonics , something to do with the vibration. I have no idea but if it’s the right type of filler ?? 4” dump to 3.1/2” to tail, pretty quiet system, less noise , less notice and that’s how I like it. With the new cam sizes I was wondering about it being a bit lumpy but with the Vcam it should be ok , small town , don’t need attention ?

Dyno graph page 119, think the PSI was 26 ish on E85 and 20 ish on 98. I was never going for high top end, would have had a 9180 bolted on LOL Had some grouting in the block , adds block rigidity and helps to prevent cracking from twisting due to torque Don't know about the block bracing/caps ??

This wasn't a build thread, wasn't intending to do all this work, like a DH I got carried away trying to get what I wanted , pretty close now and after this LAST lot , it will be all done and dusted . The 9180/1.05 should be mad , guess it depends what you are after. Mine is falling over around 6000 but still has plenty pushing it to 8000 for me , hard to use more than 6500 anywhere on the street, no need to rev the shit out of it. Nuke surge, twin Walbro 460s and a 460 p/u , -8 through to a Plazmaman rail , flex fuel system , ID1300 injectors and a shit load of sensors keeping an eye on everything that moves on the car, lol Vcam allows more low end through to running out of puff, very linear car to drive. Can't wait to see how this last lot makes the car drive, not expecting the world but it should be noticeable all the way through to limiter

I can only go off what the builder said about the section they would hand port , they have a very good reputation in the game and have turned out some special cars. I figured while it was on the CNC , let it do the lot? Do you have a build thread , 1.05 or 1.45 a/r, if I ever went bigger I would go 9180/ 1.45 , but there’s not much chance of that ? When will your work be finished , like to see the results i was hoping for a Xmas present but doesn’t look promising atm , so 2019 ?

I have no doubt porting done properly is a positive mod, it always has been. Pauls car is mad! Mine may not show the portings full potential because of the 8374 on a 3.2 , it will be falling over around 6000 , it does that now , my tuner will get the best out of it and should be a ton of fun and interesting to see the results

It is half CNC port and remainder hand ported. The throat of the port was done on a CNC machine and the remainder of the port is hand ported , cuts down a bit on cost Vs gain ? Have 1mm OS valves etc already . Pistons are from CP-Carrillo in the US , will get a few pics as it goes together . Don't know what size gasket yet, they are going thicker to allow more CR should it be wanted in the future :/ What Turbo/s are you running. What else are you doing? Doesn't seem like too many blokes do porting on their cars, guess it's because of "cost Vs gain" , other mods probably get them going going better at lower costs , well ?

Both cams going to 272 / 10.5 , could go to 11.0 Going 9.5:1 CR , they are going to use a thicker gasket , in case higher CR is ever wanted Pistons coming from the US in a week or 2 and the head is out being ported Hopefully get it back this year , LOL
