The issue with multi throttle bodies and MAP, is the turbulunce. You can get the same MAP reading, for a different throttle reading, and it plays havoc. Good ECU's, like the Adaptronic, Motec, (I also believe Haltech, ViPEC and Autronic) run MAP vs TPS tuning. I run MAP with the Adaptronic, and it has no issues at all. Actually, it has quite a few benefits... I can run NO BOV, and not have a single issue. I run an oil coated air filter, and not have it flood my AFM giving shit readings, resulting in poor idle...

The Adaptronic is an awesome unit. I've been running one now for quite a while (When my car runs that is) Currently tuning the car myself, and it's quite easy to use. Go with it, it has AWESOME support after purchase, and is constantly having new features put in it. Currently has traction control, launch control, flat shift, etc etc etc, (boost control too)

Where's your pressure source for your wastegate? If you take the pressure source from the inlet plenum, it helps smash the waste gate closed when shifting which helps bring boost on quicker... Especially if you run no BOV it will make a HUGE difference...

Run a braided line. It goes down under the turbo... Very hot down there...

mmHg is only used in VACUUM. I can't remember what the positive pressure side is measured in. But the GTS-t RB25DET R33 runs 7PSi max stock.

VCT is off below 1050 RPM Turns back on once you get above 1050RPM, then turns back off at 4500RPM...

This man, he knows... Hand brake shoes don't really "wear out" unless you're one of those gumbys who drives around with the hand brake still partially on... Most of the time, when you pull the hand brake on, the car is already stopped, so there isn't really any "wear"

So how'd those new knock sensors go with the PFC? As for doing skids, I'll rip em on the spot to finish a set of tyres of, but I much prefer throwing the car aroundo n the skid pan, sliding here and there.

Try bolting the backing plate TO the engine... It'll be easier... Just go buy one, and bolt it on. Problem solvered...

Put the factory BOV back on, OR plumb your Atmo BOV back into the intake... In the same way the Factory one does it...

Hey man, I can't exactly go drilling and tapping shit at the moment, as the head has already been service, cleaned and rebolted to the motor. I'm at the part of needing to get this oil line done, so I can put my inlet plenum back on...

Hey guys, I've been searching and digging around for some info, but I can't really find what i need... Anyway, I have an RB25DE head from an R33 (YES it HAS VCT!) Now, I had a workshop do the tapping of the hole for the oil feed to the VCT... Now my issue seems to be, he's tapped the hole on the SIDE of the head... IE, pretend you're bolting on the inlet plenum, the way that bolt is being done up to bolt it to the head, is the same way you would do up the oil fitting to the head... As in, the hole is on the side, not the front... Now, why such an issue I hear you all ask... Well issue is, when I have the little adapter, plus the oil line bolted onto it, it fouls on the water feed into the plenum. As in, the actual fittings JUST clear it, but the alloy oil line fouls it, no matter how hard you turn it, as the fittings JUST clear (As in, half a millimetre) So I went back to my local place for getting bits and pieces like this, after a bit of chatting, instead of running a straight adapter out of the head, I got a 90 degree bend so I could clear everything... ISSUE! This fitting cant be screwed in, as it fouls on the head as you turn it to screw it in (Where the stud goes through, it hits this bulge) So, I'm wondering, how have others done their oil fittings if their hole is tapped in the same spot. OR, if I plug this hole, and DON'T feed my VCT any oil at all, what issues can I encounter? Should I pull the VCT valve out and just put a plug in here too? Or would I be better off getting a fitting that will fit the VCT hole, plugging the one I tapped and just feeding constant oil up there. (I don't care right now if VCT does, or doesn't work) I don't have the cash to change cams, hence, not worried right now if I lose VCT, so long as i don't smash a motor to pieces... Any help... Thanks

Just put another RB20 box in... Should be able to pick one up for a couple of hundred, spend a weekend with a mate under the car. All done.

Okay guys, you're all noticing drops in engine temps (Bar Guilt Toy) so has it worried you that now your engine is not running at the temperature it was designed to? Maybe causing pre-mature wear? We all know it's bad to flog a "cold" engine, but is it bad to flog a cooler then normal temp engine? (IE, 10 - 15 degrees less?)

That's the one, can you PM me a price with shipping included to 2518?

Ethanol is ethanol... Or are you more concerned of the other 15%?

The fuel dampener, I can see it in one of the pics. How much for it?

on the exhaust side of the engine, on the actual side, but at the front, there is a big hexagonal "thing" which has an electrical connection. It sits just behind the back of the cam cover. You can see it without removing a single thing.

Dirt Garage: I think what Shanef is getting rather annoyed about, is the fact you keep talking up the Vi-Pec, when ever he asks for info why it's so much better, you just tell him to ring someone else... It's as though you don't understand why it is a technically more advanced ECU, and that shows that this ECU may not be technically more advanced. Give some actual info as to HOW it is so much better... Not just say "Ring so and so, they'll tell you" We want YOU to tell us, since you're pushing this product so hard...

If you have a pod filter (And even if you don't) clean your AFM. It'll help MAJORLY. Pod filters often are filled with oil, this sucks onto the AFM, and stops the air flow from cooling the hot wire, which makes the ECU think there is different amounts of air going in to what there is. To clean the IAC valve the easy way, go to Subaru, buy a can of Subaru upper engine cleaner. Follow the directions on the can.

Take a look at the Adaptronic, it's only downfalls I can see with the current e420c that people can pick up: In the GTR, it's not plug and play, you need to cut and solder the looms. It runs semi sequential injection, and wasted spark ignition. Doesnt' come with an IAT sensor ("downfall" since it's a map ECU) It has launch control (When you just switch to kill ignition, works very similar to anti-lag), traction control, flat shift, boost control, dual maps, MAP * TPS tuning (Perfect for ITB setups!) full support and upgrades from the people who make it themselves, it's 100% australian owned and backed, the BEST support you could ever get. Also a feature in the ECU to let you know if more ignition timing will make more power or less. (Is very handy when tuning for peak power on NA cars) RRP of ECU on last check $1000, RRP of loom was like $99 plus I think like $150 for a 3 bar map sensor... Adaptronic also have a new ECU due out very soon, that from what I've heard from testing, tunes take all of about 5 seconds to get a start up and make th ecar move tune... Couple with the auto tune feature the Vi-Pec is sporting for "30 minute tunes) that Adaptronic have been using for a few years now... You can be assured a sensational tune... In 30 minutes!

Yeah, basically a stock GOOD Nissan one... As for bubbling, you have air getting in somewhere... This is NOT good... I'd be looking at your heater core for the cabin, radiator cap, and then looking for BHG signs... PS: Pressure test will not show up the signs of a BHG... Mine went in 3 spots, from water gallery to cylinder, still held full pressure in the radiator for 5 minutes! Also check your over flow bottle... Make sure it's full... Something is definitely a miss, and I'd be getting nervous driving with 100degree water temps. You're running a forward facing plenum aren't you? So you no longer have the bleed point on the plenum... Also, Would it be possible for you to send me a copy of your ignition timing map for Petrol with RPM VS Boost. I want to tune my car possibly this week (If I can get the oil fitting I need) but am a bit onsure on ignition timing, and since I'm not running a PFC, I can't just "keep knock below 40" as my knock values are TOTALLY different ot that of a PFC... And when you tune for E85, without recalibrating your O2 sensor for the AFR of ethanol, do you just tune for the same AFRs etc. (14.7 as stoich, less then 12 for on boost power etc) Also, what AFR are you aiming for on petrol, when just cruising on the freeway?

Do you happen to have the fuel dampener? The one that sits on the drivers guard on the return line. Basically sits next to the fuel filter, looks like a fuel regulator, but has no vacuum line going to it, just a fuel in, and fuel out? I need that and the bracket holding it to the guard if you have it? PM me back if you do.

Top feed injectors, so much easier to change! Go with GTR rail! As to the coolant issue, just throw a thermo fan on instead!

When I did my sards, I found my 870cc came with the right o-rings, and hence, fitted in VERY tightly. As to the cap, I had to remove the little rubber bit in the cap end to make it fit on.
