righto, heres a run down on my research so far, figures are aproximate power gains and bang for your bucks (nz dollars)

extraxtors 5-6rwkw $350

Nos (50hp shot) $1600

cam gear inlet only 2-4rwkw $250

cam kit (run with standard ecu) 10% gain $795

SAFC II 10-12% gain (tuned) 2nd hand $450

hope that is of some help.

Ok, so you are going to go turbo.

Have you thought about buying a GTS25T that has been witten off in a accident, that way you will have all the bits you need and just swap them over to your car. Stronger engine, gearbox, better brakes, suspension and not to mention intercooler.

1 1/2 years ago we looked into turboing ours, we found the cheapest way was to buy a wreck ($3000) and change all the bits over. We didnt do it, and $3500 later I still haven't broken into the 15's for the 1/4, if only we had turboed it.

Just something to think about.

And with your sort of budget you should be able to upgrade the exhaust system, CAI, intercooler, boost controller and a few other bits as well.

ive changed me mind...

im either considering buying a 200sx S15...theyre just absolutely gorgeous...a newer car and just slightly more expensive.

if im gonna spend money on the car, i wanna make sure it has residual value eventually....so maybe a s15 is the way to go...

if not then ill do up the skyline i guess

:P

guys, with 10k or so.

what kinda power shd i expect?

im sure there wd be a few routes to take...ie rb25DET

or rb30 with 25DE hybrid kinda thing.

what would be the best route to take?

and what kinda powers to expect?

what would be the best route to take?

1.) obviously it would be cheaper to sell your car and buy a turbo version

however.

2.)you said you were after some more power you could always buy the 1997 rb26dett and put that thing in :P im not sure how much it would cost to install but running that thing on more boost etc compared to your n/a would feel like heaven :(

with 10k u can just do it, u take a vl turbo bottom end, balance the crank, shot peened rods, all new bearings, GTR head, Custom Plenum, Microtech MTX-12, Forged pistons, Custom Exaust manifold/s, and a pair or single turbo that matches ur budget, This is an awesome setup, even with high flow GTR turbos 350-400 hp at the crank is very achievable, if theres more money bigger turbo's and away u go!

NA-R33...

better to sell the GTS and buy a T or do this baby up?

im kinda attached to it and its in a great condition but i can make more power out of a T with the same money

yr suggestions?

seeing u haf been struggling w the power issues for as long as i prob haf after buying an NA

haha, yeah im atached to mine to, i cant sell it. The Microtech LTX-12 engine management is about 1500 bucks, a turbo gearbox would be in order, though i never budgeted for that as i was gonna drive mine till i broke it with the new engine.

yes there is list as long as my arm of things, basically my mechanic said 10g's would get me there, im not building this engine myself nemore im going a different route but the rb30 with gtr head built right has some serious potential.

10k .. better to sell what u got .. u'll get something like 15k or so .. add in that 10k and u could get a modded one already for 25k. thats the easy option .. plus u get to test the car out to see if u like the power ... thats what i would do if i was in ur position.

    • Cheers. Skyline is back on the menu, can’t get rid of it. It’s like a child you don’t want, or herpes 
    • I got back to Japan in January and was keen to get back on track as quickly as possible. Europe is god-awful for track accessibility (by comparison), so I picked up a first-gen GT86 in December just to have something I could jump into right away. The Skyline came over in a container this time and landed in early January. It was a bit battered after Europe, though—I refused to do anything beyond essential upkeep while it was over there. The clutch master cylinder gave out, and so did the power steering. I didn’t even bother changing the oil; it was the same stuff that went in just before I left Japan the first time. Naughty. Power steering parts would’ve cost double with shipping and taxes, so knowing I’d be heading back to Japan, I just postponed it and powered through the arm workout. It took a solid three months to get the car back on the road. Registration was a nightmare this time around. There were a bunch of BS fees to navigate, and sourcing parts was a headache. I needed stock seats for shaken, mistakenly blew 34k JPY on some ENR34 seats—which, of course, didn’t fit—then ended up having the car’s technical sheet amended to register it as a two-seater with the Brides. Then there’s the GT86. Amazing car. Does everything I want it to do. Parts are cheap, easy to find, and I don’t care what anyone says—it’s super rewarding to drive. I’ve done a few basic mods: diff ratio, coilovers, discs, pads, seat, etc. It already had a new exhaust manifold and the 180kph limiter removed, so I assume it’s running some kind of map. I’ve just been thrashing it at the track non-stop—mostly Fuji Speedway now, since I need something with higher speed after all that autobahn time. The wheels on the R34 always pissed me off—too big, and it was a nightmare getting tires to fit properly under the arches. So I threw in the towel and bought something that fits better. Looks way cleaner too (at least to me)—less hotboy, less attention-seeking. Still an R34, though. Now for future plans. There are a few things still outstanding with the car. First up, the rear subframe needs an overhaul—that’s priority one. Next, I need to figure out an engine rebuild plan. No timeline yet, but I want to keep it economical—not cutting corners, just not throwing tens of thousands at a mechanic I can barely communicate with. And finally, paint. Plus a bit of tidying up here and there.  
    • Nope, needed to clearance under the bar a little with a heat gun, a 1/2" extension as the "clearancer", and big hammer, I was aware of this from the onset, they fit a 2.0 with this intake no problems, but, the 2.5 is around 15mm taller than a 2.0, so "clearancing" was required  It "just" touched when test fitting, now, I have about 10mm of clearance  You cannot see where it was done, and so far, there's no contact when giving it the beans Happy days
    • It's been a while since I've updated this thread. The last year (and some) has been very hectic. In the second-half of 2024 I took the R34 on a trip through Germany, Italy, France and Switzerland - it was f*cking great. I got a little annoyed with the attention the car was getting around Europe and really didn't drive it that much. I could barely work on the car since I was living in an inner-city apartment (with underground parking). During the trip, the car lost power steering in France - split hose - and I ended up driving around 4,000kms with no power steering.  There were a few Nurburgring trips here and there, but in total the R34 amassed just shy of 7,000kms on European roads. Long story short, I broke up with the reason I was transferred to Europe for and requested to be moved back to Japan. The E90, loved it. It was a sunk cost of around EUR 10,000 and I sold it to a friend for EUR 1,500 just to get rid of it quickly. Trust me, moving countries f*cking sucks and I could not be bothered to be as methodical as I was the first time around.
