If you are going to go to the expense and hassle of doing an engine swap you should really consider something that is going to give a significant performance increase as the RB20 NA to RB25 NA isn't much of an improvement. Have a chat to Nick, he is a good bloke and is going through an LS1 conversion at the moment. Nick is pretty easy to track down, he only has one leg, a special arm attachment for his ratchet shifter and captains the fair ship Natro. Here is an artists impression:

Bahaha, thanks bro... Loving the artists impression :thumbsup:

Going from a 20e to the 25de you'll deffinetly notice a difference, but... It still won't be a rocket ship, but it will have alot more "go" refer to the "Are Natro Rbs really that slow" thread.

My conversion is a lot more difficult then what a turbo rb swap would be into the r chassis you have. So like i said before go and have a read through the "how to turbo your NA" thread or track down a turbo rb donk, either way you'll need an engineers mod plate and have to alter your rego/insurance details :)

Sorry mate thought this was another thread ive posted in that was similar, to cut a long story short.

You've unfortunately found yourself with possibly the worst skyline combo you can buy :(

question number 1... Are you on your Ps? If the answer is yes then scrap the whole thing as you'll require a mod plate instantly disqualifying you from legally driving it (regardless if its NA or not)

So you can't do any of the work yourself, this is a major disadvantage as a work shop is going to charge you $70 an hour just in labour alone before they ad parts on top of that.

....have a search around the place on here regarding (Natro) engine conversions I'm sure you'll find something.

(I have a feeling you'll be shocked by how much this will end up costing you if you went down this original route)

Are they slow? (first few pages are relevant, the rest is rubbish, partially my fault lol) http://www.skylinesaustralia.com/forums/topic/417003-are-nas-really-that-slow-or-are-people-talking-out-their-ass/page__pid__6722430__st__320#entry6722430

    • 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
    • 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.
