steamed prawn (ebi) bun yum, but in that wierd way

The M3 had to have the best I6 I've heard IMHO. I don't why, by it sounds great. I'm spewin that the put v8's in the M3s now. They should make an M1 and put the old M3 engine in it. On the flip, I just heard a new M3 scream past the other day, I'm not so spurious anymore. It was fkn good. Skyline sounds so much more advanced over any road going 4 cyl. (Maybe not the rally cars though...)

Sounds awesome. Very inspiring. After watching this thread for ages, it's good to finally see the results. Have you got a rear wing planned for it?? Might help with some rear traction on the high speed corners..

Don't be a pusseh. Get an ECU. If cost is a problem, sell skyline and get a barina.

Then look into a daughter board. it goes into your ECU box. Toshi or dr drift maybe has these? Also, EMU's like gready emanage uses your stock computer as well, just hide the emanage or something. Your a member of vic SAU, so talk to them an see how they go about tuning their computers. The stock computer is so stupidly out of tune at 12 PSI that putting it back to stock PSI will improve the tune if anything.

A tuner told me that 12 is the limit for these ceramic turbines, so adjust the controller to 10 so it will only creep to 12. Your choice of course. Then, save up and get a new computer (ECU) and get it tuned. You'll have no smoke or black bumper and more power everywhere. the only other thing I had to do was get a fuel pump as mine wasn't pumping enough. Do it all together to save having to retune etc.

Sounds like boost creep. So as I said earlier, there a whole lot of conjecture about what causes it. I had it, thought it was the wastegate flap hitting the bell mouth dump, but wasn't it. Did a lot of searching and found a few people with it, but no real answers, just suggestions like bad boost controller etc. Then one day, A guy on here had it and he got a PFC and had it tuned, and his boost creep dissapeared. It was figured that the rich and retard that you get from an untuned stock ECU with more boost and some basic mods causes excess pressure in the mainfold due to Exhaust gas still burning as it exits the cylinder. Rich and retard does that, kinda like antilag tuning does the same thing. Not everyone seems to get boost creep either. SO anyway, other people are getting boost creep for other reason as as well, but this was more to do with bigger turbo and bigger highmount mainfolds, different story. I had mine tuned using a SAFC equivalent and it fixed the problem somewhat. That is all...

Well you haven't explained yourself very well. Here's example of creep versus boost. The boost creeps from 12 to 14 over say 5000rpm. or it hits 12 at 2500rpm and then spikes to 14 at 2700rpm. which one is it? If it's creep, then you need to get a ECU and get a tune. There's a whole lot of explanation and debate as to why, but this is the proven answer. If you need to know why, then search. If it's a spike, then look for the aforementioned restrictor. The solenoid needs it to control the boost properly, and you don't need it for the boost controller.. Boost controllers tend to spike a little anyway. Do what ^guilt-toy says and get back to us.

Yeah, the solenoid is there, the orangey brown one plugs into it. The orngey brown is the bleed off, which I thought goes back to the turbo intake. I think theres a restrictor in the pipes somewhere, possibly in the red one. Check this for flow... I can't be sure... The setup looks right though. Did you pull a t piece out of this setup and replace it with the boost controller?

You say it's happening in only 1st and second, but not third or more? Sounds like a boost spike.

Any mods?

I'm not much real help, but I've seen it done for drift cars... so it can be done. However, it wasn't for a skyline. Speak to a suspension shop that sets up drift cars, if anyone's going to know anything about it, it'd be them. I'd start there.

lol. OK. Not the answer i was looking for though... I've edited your quote for you

Do you need a catalytic convertor with e85? Anyone measured the emissions with out the cat?

AFAIK, The ECU will be OK, after a dynotune/remap. Some RB25s don't use igniters, some do, so check with an engineer/mechanic if this makes a difference. The turbo is different in the RB25, it's bigger. This means you'll get less performance out of the RB20 turbo on the 25 which negates the purpose of getting an RB25 in the first place. The response may be quicker, the low down torque may be better, but overall power will probably be down. I've not heard of anyone putting a 20 turbo on a 25. People with RB20's upgrade to 25 turbos all the time.. Otherwise you might as well get another RB20. Your exhaust can prolly be modified by an exhaust shop to fit the new turbo, if it even needs it. Pretty sure bolt patterns are the same. Shouldn't cost that much. The gearbox from the RB25 is much stronger. I would get it, as the 25 enigine may break a RB20 gearbox. That's all I can think of right now.

32 bit o/s addresses 4 gb of ram, including your video card memory. I'd say your graphics card has 750mb... 64bit FTW And yeah, +1 reformat/reinstall

Is that N/A or boosted tough. E85 would be awesome if you were turbocharging a normally N/A car. No need to reduce compression.

So, Can you run higher compression on E85? Would it yield more results? Hypothetically, Say you were building and engine and you plan to run it on E85, a stabler fuel should allow for more compression, yielding more power. Especially down low, and off boost. Of course, I've no idea what I'm talking about. Furthermore, I guess there's no going back to 98pulp after you build a high comp engine. And on the track, most engines are on boost rather than off. So it's prolly not viable. But is it possible?

Hey Roy, I would tend to agree with ^. It'll prolly take a year of e85 for enthusiasts to publish the best way to tune it, etc. it's a bit like a new operating system on a computer, untested, with lots of bugs that will eventually be ironed out. The cons are mixing your own water/meth cocktail every 2 weeks and keeping a drum of flammable liquid in the garage. However, water/meth with pump fuel has given 'the mafia" good results. Otherwise, you may wish to be one of those enthusiast, more powa to ya!

So, was it cost effective?

i hate to be a smart arse, but nissan did it. They took a gts4 and put in a rb26 a well as giving it a wide body kit and some more guages, among other things. They called it the skyline gtr. Seriously though, why do you want to go down this path? Cost? how much do you think you will save? Something different perhaps? Found a cheap gts4? Doing it for a challenge or hobbie? etc...

oh, it appears I'm too late.

Hey guy, I think 'the mafia" did a gt30 with a .63 rear end. Search for his threads. I dunno if you're already onto it, but it makes for a good read. Also, just something I would consider if I was in your shoes... Why don't you use the GT35 with a ext gate setup until you get your 3.0l from what everyone on hear says, the ext gate spools the turbo quicker, and then you have an upgrade path. You may or may not want a .82 rear house when you 3.0l, but that's then, not now.

I don't understand the whole consumer confidence thing versus the $2 a litre. How do you figure that?
