Not shattered, enlightened.

Mine pushing just over 500hp ATM on 98, all I need is bigger fuel system to run E85 for more powers.

My new engine set up cost around 15k, that was a built 25/30 with a steam pipe exhaust manifold, turbo, Ross balancer and CAS, and some fabrication and tuning.

BUT

At 500hp the traction issues with a RWD become blatantly obvious, useless power is useless unless its a dyno queen.

Remember though a well set up 500hp RWD car should do a high 10, or so Im lead to believe, mines run a 11.130 so there is hope.

Think, plan, appraise, plan, do.

Heh heh traction.. im not worried about that

I've got an RB25 here that isn't built yet but is ready to measure and assemble. It has Ross Racing pistons, Eagle forged conrods, ARP main studs and ACL race series bearings. It doesn't have a crank collar fitted (I was going to go external sump) but I can have one fitted free of charge. Wanting $4.5k and will come with warranty. No cylinder head

is it really such a hassle, plenty of result for a gt30/gtx3076 can make 500hp, its only 375kw's

so why not just put some forged pistons and a balanced bottem end in, and add the bolt on's?

all items could be bought second hand in the classifields, job done

Or you could just get your tuner to tune your car Boost over Speed.

I would dare say you'd need rods aswell... last thing you want is rod bolts being your un-doing.

There are alot of good results with GTX3076s... but I would still go a GTX35.... yes added lag but more power especially on 85...

Or just go a Precision... I have heard nothing but good things and I am myself thinking of going a Precision 6262 for my GTR

I would strongly suggest go see EFI and Elite if in the Brisbane Area. They are my Builders and Tuners, top blokes.

The best thing you can do is form a total understanding of what you plan to build. Know and understand every part and don't leave a stone unturned. Put this all on paper.

Next step is to make phone calls and send emails to put dollar value to everything you know.

I definitely think 20k can scrape through.. but that is assuming you don't change anything drivetrain related. Motor setup and clutch only, tuned.

I recently built my own motor. Cost me 3500 in rounded up figures to build an SR that will hold the power your talking about. I kept the head very simple but I think I could get it there within another 1500 (5k total). All work done by me, except machine work.

it will be a long difficult process to keep it under 20k but you can do it.

Been thrashed i assume.. wow money gets you f**k all now days

Well of course it's been thrashed, why else would you build an rb26, to baby it? Put put around the city? It doesn't matter anyway as long as it has been built right and maintained properly. Why else are you planning on spending 20k on a motor to chase big power? I assume when you looked at buying your skyline you were looking for a car that had this in the ad right? "never boosted, never thrashed, never see a track" If you were to buy a motor you would be pretty stupid to not get a compression and leak down test done to it anyway to make sure it's in good shape.

easy .. but aim for less ... some sort of rb25 combo whether standard or built a little ie: bottom end appropriate bolt ons that everyone else uses to get that power (6boost, ex gate, gtx 3076 or similar, injectors, pumps) and on e85 get 450 - 500hp tops safely, spend the money left over on suspension, tyres and seat time

still need to be able to put 500 - 600 hp to the ground in a drift car... drifting is just as much about grip as turning tyres

unless your running a great suspension setup and an awesome big tyre you will find anything over 450 - 500hp pretty useless I think

Im running 440ish hp with just about every suspension thing you need etc etc on decent 265 18" tyres on 18 psi and dampers near full soft in rear for drift and still searching for more grip and turning those tyres like crazy as are most others around that mark and are competitive at a good level

unless you are going full Pro spec and can afford great tyres... .. Its not really needed imo...

The Borg Warner s300sx series is an awesome turbo for its price

on a baby 2.6 its brilliant. Even on low boost and 50% ethenol the power and response is excellent

the turbo cost me $950... couldnt be happier atm

the twinscroll manifold and plumbing up the gates was the $$$$ part :P

as already stated, its the little things that add up very quickly, but its the little things that bring the whole set up together to make it work

Or you could just get your tuner to tune your car Boost over Speed.

Have talked about this but the logistics is a PITA, does it get tuned boost/road speed for the drag radials or the semi slicks or the road tyres.

To be honest its only the drag radials or semis that get a flogging but the traction difference between the two is fairly large.

The drag radials on a prepped strip are near perfect for the boost, the semis could do with some more work in this area though, but the poor old Hankooks Ventus RS3 street tyres though are in trouble everywhere under the top of third.

For a all rounder the tuning does suffer a bit due to the different amounts of traction for different disiplines, if it was street or track only the issues would be easly fixed, but alas Im trying to do three things with the one car.

Is fun though.

    • You are selling this? I have never bought something from marketplace...i dont know if i trust that enough. And the price is little bit "too" good...

    • It would be well worth deciding where you want to go and what you care about. Reliability of everything in a 34 drops MASSIVELY above the 300kw mark. Keeping everything going great at beyond that value will cost ten times the $. Clutches become shit, gearboxes (and engines/bottom ends) become consumable, traction becomes crap. The good news is looking legalish/actually being legal is slighly under the 300kw mark. I would make the assumption you want to ditch the stock plenum too and want to go a front facing unit of some description due to the cross flow. Do the bends on a return flow hurt? Not really. A couple of bends do make a difference but not nearly as much in a forced induction situation. Add 1psi of boost to overcome it. Nobody has ever gone and done a track session monitoring IAT then done a different session on a different intercooler and monitored IAT to see the difference here. All of the benefits here are likely in the "My engine is a forged consumable that I drive once a year because it needs a rebuild every year which takes 9 months of the year to complete" territory. It would be well worth deciding where you want to go and what you care about with this car.
    • By "reverse flow", do you mean "return flow"? Being the IC having a return pipe back behind the bumper reo, or similar? If so... I am currently making ~250 rwkW on a Neo at ~17-18 psi. With a return flow. There's nothing to indicate that it is costing me a lot of power at this level, and I would be surprised if I could not push it harder. True, I have not measured pressure drop across it or IAT changes, but the car does not seem upset about it in any way. I won't be bothering to look into it unless it starts giving trouble or doesn't respond to boost increases when I next put it on the dyno. FWIW, it was tuned with the boost controller off, so achieving ~15-16 psi on the wastegate spring alone, and it is noticeably quicker with the boost controller on and yielding a couple of extra pounds. Hence why I think it is doing OK. So, no, I would not arbitrarily say that return flows are restrictive. Yes, they are certainly restrictive if you're aiming for higher power levels. But I also think that the happy place for a street car is <300 rwkW anyway, so I'm not going to be aiming for power levels that would require me to change the inlet pipework. My car looks very stock, even though everything is different. The turbo and inlet pipes all look stock and run in the stock locations, The airbox looks stock (apart from the inlet being opened up). The turbo looks stock, because it's in the stock location, is the stock housings and can't really be seen anyway. It makes enough power to be good to drive, but won't raise eyebrows if I ever f**k up enough for the cops to lift the bonnet.
    • There is a guy who said he can weld me piping without having to cut chassis, maybe I do that ? Or do I just go reverse flow but isn’t reverse flow very limited once again?
