If we are talking about useable power for the street then no one should go over 300kw like anfanee said.

And let's be honest pete, your original setup was a donk from the dinosaur ages and you will forever be scorned with "ultimate lag".

Built 2.6 vs 2.8 Same duration cams Same fuel Same dyno and tuner Same turbo's Same ECU Not sure what you'd prefer.... I'll give you a guess which engine is which.. Carry on...

The beauty of a responsive big power stroker is you can still pretend it's heaps laggy with the throttle, if that's your thing. Can't pretend a lag monster is responsive...

There is definitely something wrong with you. I liked your post, but there is definitely something broken!

ibomu hits full boost at 7,000rpm... Is it ideal for the street?

He drives it on the street?

And it's one of the most powerfulest gtr in the country.

Each to there own how they want there car setup.

I have said that a 100 times, it is your car, mod it and drive it the way it makes you happy, the end!

I have copped a lot of crap because I wanted response, I never put shit on blokes that want what they want. But for me getting full boost at 7000rpm for a street car, is nuts , it is a waste of power. If I could have gotten what I wanted at 300kw, that would have been enough. As a new bloke to all of this, I am sure I did it the wrong way, but ?

My built 26 would rev 10,000rpm +, you could not rev to 7500rpm in 2nd without speeding on the freeway, that was only 1000rpm after the boost kicked in, oh and that is after struggling up to 5500rpm to get it to start to move unless you drop it at 7000rpm +, then your head would fall off, so, was this a street car, not for me and I am the only one that counts. My Tiida would blow the bloody thing off the road from an idle start and a lot easier to drive

I can have fun throughout the rev range and unless I am playing I do not usually go over 4000rpm, the acceleration is linear and no surprises, comes on smooth and as hard as your right foot dictates .

I reiterate my previous statement.

That car is not good to drive on the street, at all, he is making power "Just because"

Before you even know it you are doing well over double the speed limit. It's completely useless.

300-350kw is the sweet spot of power you can actually use. anything else is really overkill for a dedicated street car.

If the power is usable , 300kw is more than enough

My original setup was 338kw and shit for a DD, my mistake :( so I changed it, here is the 26 Dyno with the different turbo and cams , it was OK but for me still a crappy street car. But more than enough power for the street, probably different turbo and cams would have fixed it for what I wanted, but ?

Now I have some torque to get it rolling and the power can be used much better than something that kicks in at 7000rpm, I have changed gear before then and have fun on the speed limit, advisory speed signs are good for direction :yes:

I get that, AND wheel spin from 3500 rpm in a GTR. I'm with you Pete, lag is for those that watch too many internet videos and don't actually drive their car in the real world all that much.

I recall driving my old near stock R33 GTR. From the lights a few years back, and shifting below 3500 rpm I was dragged off by a bloody prius taxi! That same car made 270kw on stock turbo's with all the bolt-ons, and was by all accounts what many of you call "responsive".

I agree, 300 kw atw is nice, but at 4000 RPM thanks.

Now your talking, 4000rpm for 300KW rules for the road. :yes: I think I will try for 400KW @ 4000rpm as it is an easier number to remember, response, response , response :wub:

Guess we should all bolt -10's on, no need to be fast in city traffic so we can go for full track setup then

Depends if you want to be a hero at every set of lights, fark you better beat those corollas.

As I said, I have never had problem keeping up with traffic with 0 manifold pressure, and at atm I am running mine in with a weak tune and 5k limited, again with no issues. But then again I don't like being a street hero when I am taking the kids to school or going to work.

Yeah go get them Pete. Give those Prius's and Tiida's heaps..

Last time I checked in peak hour maximum speed is 60 km/hr if your lucky. Must be so good to be on boost.

haha, I do not live in the City, 2 minutes down the road it is 80 another 2 minutes it is 100 and 50 klm of country road that has all of the features that make driving fun and I do it up to 7 days a week :yes:

I leave the City driving to you poor bastards :angry:

Oh and at the end of my road there is one of the best hill climb roads in NSW , Wooton Way. Mmmmm it is like driving heaven :wub:

      Duncan's V37.......race car?

      By MBS206 · Posted

      Even more fun, leave all the ADAS stuff plugged in, but in different locations, hopefully avoid any codes!   And honestly, all these new cars with their weird electronics. Pull all the electronics out Duncan, and just shove an aftermarket ECU and if needed a trans controller in, along with a PDM. Make it run basic but race car styled!

      To follow up a question from earlier too since I had the front bar off again (fking!) This is what is between the bumper and the drivers side wheel And this is the navigator side, only one thing but its a biggy! So basically....no putting coolers in the wheel arches without a lot of moving other stuff. Assuming I move to properly race prepping this car I'll take that job on and see how the computers respond to removing a whole bunch of ADAS modules

      Duncan's V37.......race car?

      So I prepped the car for another track day on Wednesday (will be interesting to see coolant temps post flushing out and the larger reservoir, with a forecast of 3-14 being 20o cooler than last time I took it out). Couple of things to mention; since I am just driving the car and not taking a support vehicle, I took the rear seats out and just loaded the back up Team Trackday style. Look at all that space! To cover off removing the rear seat....it is weird (note the hybrid is probably different because it wouldn't have folding rear seats) Basically, you remove the lower seat base, very similar to a r series but it is a clip that pulls forward to release the base rather than it being bolted down. Easy Then, you need to remove the side section of the rear seat on each side. There is a 14mm head nut at the bottom of the side piece, the it slides upwards off a hook at the top to release; you also need to unhook the seatbelt from the loop at the top. Then the centre piece is weird. You need to release/fold the seats forward with the tab in the boot on each side From there, there are 2,x12mm headed bolts holding the rear of each seat to the folding bracket, under the trim between the rear seat and the boot (4x christmas tree clips there, they suck). The seat is out but you can see where the bolts attach to the bracket

      As discussed in the previous post, the bushes in the 110 needed replacing. I took this opportunity to replace the castor bushes, the front lower control arm, lower the car and get the alignment dialled in with new tyres. I took it down to Alignment Motorsports on the GC to get this work done and also get more out of the Shockworks as I felt like I wasn't getting the full use out of them.  To cut a very long story short, it ended up being the case the passenger side castor arm wouldn't accept the brand new bush as the sleeve had worn badly enough to the point you could push the new bush in by hand and completely through. Trying a pair of TRD bushes didn't fix the issue either (I had originally gone with Hardrace bushes). We needed to urgently source another castor arm, and thankfully this was sourced and the guys at the shop worked on my car until 7pm on a Saturday to get everything done. The car rides a lot nicer now with the suspension dialled in properly. Lowered the car a little as well to suit the lower profile front tyres, and just bring the car down generally. Eternally thankful for the guys down at the shop to get the car sorted, we both pulled big favours from our contacts to get it done on the Saturday.  Also plugged in the new Stedi foglights into the S15, and even from a quick test in the garage I'm keen to see how they look out on the road. I had some concerns about the length of the LED body and whether it'd fit in the foglight housing but it's fine.  I've got a small window coming up next month where I'll likely get a little paint work done on the 110 to remove the rear wing, add a boot wing and roof wing, get the side skirt fixed up and colour match the little panel on the tail lights so that I can install some badges that I've kept in storage. I'm also tempted to put in a new pair of headlights on the 110.  Until then, here's some more pictures from Easter this year.

      I would put a fuel pressure gauge between the filter and the fuel rail, see if it's maintaining good fuel pressure at idle going up to the point when it stalls. Do you see any strange behavior in commanded fuel leading up to the point when it stalls? You might have to start going through the service manual and doing a long list of sensor tests if it's not the fuel system for whatever reason.
