Entitled to opinions maybe, but have you heard of the phrase "If you don't have anything nice to say, don't say it"? There was nothing constructive about what you said. I know quite a number of people with EVOs that would probably make you cry if you went for a ride in driven hard.

Haha - while that is being mentioned, I have discovered that 10psi -> 11psi is the threshold where my car moves from being able to go into second (I dont flat shift) and get the rear wheels scuffing but still accelerate hard, and being able to go into second and start a fairly impressive second gear burnout

I'll have to check that out when it gets to NZ..

Thats pretty much what I aspire to getting, I haven't had the pleasure of experiencing one myself - but they sound good.

I run mine on about 10-11psi MAX and I am quite happy with the performance of the car at that boost level... if I want more power then I will probably just go for a larger turbo and sell on my still healthy R33 turbo, and know I can get that much more power reliably

To be honest, aside from the fact that I am in NZ and you are in Oz (currency, and that certain parts are more available, and others less on this side of the Tasman), I couldn't really say off the top of my head. I haven't looked at NA mods for a Skyline, being that mine is a 25T - and my previous mods were all for a 4cyl. Realistically the homework on pricing should really be up to you - it would be easier for you to find out the prices... you can pick the parts you like most etc, as that is a whole new discussion that could be had. Off the top of my head, I'd budget $10k and then go from there, you SHOULD be left with change.

Damn, I wrote a big response to Viscount but it seems my post has disappeared, or never actually saved properly!? Anyway, yeah - the compression, the exhaust, the intake and the exhaust manifold will be either incompatible or inappropriate for turbocharging. I'd recommend one or the other, a turbocharged RB25 that is in its peak between 4500-7500 is going to be a lot more extreme than the scope of this thread

The way things are at the moment, with both the RX8 and the 350Z - the manufacturers have given themselves room to improve and get feedback on what people want more. Unfortunately if they released the perfect package straight off, they wouldn't be future-proofing themselves... though it also means the customers (or journos??) get to have their 2c input into the design based on their reactions of the 1st generation of each.

I personally don't like the idea of a 4cyl in the BMW, I am used to and prefer the sound of a nice tuned sounding 6cyl coming from them.... one of my mates has a 3-series with a 1JZGTE in it putting out 218kw @ wheels and that goes plenty well

Sweet, with good driving 11s should be quite doable! SOLID 11s even.

Seeeeeeeee?

Interestingly enough I pick the R33, and also for all the things you say above :Oops: My car usually gets better economy than my friends (who the majority of have R32s), is quicker than most of the R32 GTSts, is more stock (a comparative performing R32 GTSt has had more spent on it including purchase price than mine + mods - but then the prices in NZ might be different) and runs less boost than most of them, and is a much newer car. On the down side, the R33s need bigger parts to get more performance - having a bigger motor and a heavier curb weight. Where an R32 GTSt can upgrade to an R33 turbo (which I guess brings it closer to an R33s territory) an R33 needs something big, or 2 of them

If its anything like the shrill whine/squeel that mine has recently developed at a similar boost level - I think or at least hope its because of a slight exhaust manifold leak I have recently discovered....

Yeah, you have 12 points for 2 throttle positions - so 24 all up, 12 for high throttle and 12 for low throttle. Each one, you can preprogram the 12 positions - and the S-AFC2 makes a rough curve-to-fit to work out the appropriate adjustments in between. You could have 1 fixed adjustment from 1000-2400rpm (where the wastegate seems to open on a stock R33) and then get 2/3 adjustments between there and 4500rpm for a bit finer tune there for driving around, and crap all the left overs between 4500rpm - 7000rpm... as you probably want your finer tuning in your "operating" rev range for racing etc

Ahh ok - so the R32 actuator is a good (price wise) alternative The ultimate would be getting an electronic boost controller then, but the better actuator is going to make its life easier... when I eventually get that sorted.

There is an R32 GTSt being put together in NZ with an RB25DET motor at the moment which is a "street car" - is running a VERY high mount TA51 on it, I suspect that should be able to get out of the 300-400rwkw zone :wassup:

Update - I have an R32 GTSt actuator on my car now On "stock boost" I am running 10-11psi, seems to come on stronger - feels particularly meaty around 4000-4500rpm. I find it hard to tell if its any better up top, there is definately a LITTLE drop off in the high revs. It will be going on the dyno on the 21st August for a boost and power read out, to see what the difference (if any) really is

The air flow meter probably maxed out - mine reached around 5volts airflow on around 1bar... so I'd watch what I do with fuelling after the point that happens. Someone I know blew their RB25DET recently by not compensating for what happens after 100% flow of the AFM is reached - so more air, no more fuel, lean out - detonation, death :ghost:

My first ride in a Skyline that I can remember was in an automatic R32 GTS4 a few years ago. My impression? Highly disappointed. I couldn't believe it was a turbocharged 6cyl that was (trying) to push it. Handled well though, and nice to drive on the open road. Sounded nice too I haven't really got over my grudge for RB20DET GTS4s since either.... I had been in a lot of pretty modified V8s etc at this time though, and had high expectation based on what I had seen GT-Rs doing, and also from hooning around in a 300hp turbo Commodore :headspin:

No bad, only 2 weeks behind us!

The old 4AGZE is actually a really good motor, ports are good sized for boost induced power - the bottom end is very very strong, and the ECU and injectors are reasonable overrated for stock. Get a supercharged one, a semi decent intercooler, a turbo (EVO TD05's work real well I've heard) and an aftermarket ECU and you'd get a light car without the hassle of an engine transplant etc and over 300hp. I know plenty of people who have done it, with excellent results.. I also know a guy with an AW11 MR2 ( the early shape I assume you are talking about) with a 3SGTE from a late model 2l turbo MR2, it is happily a 12s car. Anyway, this is a Nissan orientated forum so I should shut up now

That might be because its either not out in Oz yet, or just because no one has seen it there yet :headspin: Considering I think the first 4 standard out OK, then got progressively shite - HO4 being the best quality utter shit I have ever seen - I think I am pretty neutral. High Octane Overboost is definately worth a watch. Don't ever watch HO4.

Yeah, this one is maybe 10% crap - which is still more than I'd like, but its better than the previous one with the trip to the US which was pretty much 99.9% crap. High Octane 4 is the 2nd worst car video I have seen (Max Power - Beasts From the East being the worst) and High Octane Overboost is the best...

What mods do you have? If its relatively stock I'd try an ECU + dyno tune and a lighter flywheel.
