Not personal, other than I sell these injectors and field the same questions daily. It's not my job to tune the car, yet surely a good tuner can work out some simple lag and voltage charts, especially when they are supplied... Is it really that hard? Perhaps they should stick to Sard injectors or carbies.

This is the main hassle. I can do a kit for the short 1400's, as I fitted a set to a 33 and made the spacers to suit, but the 1000's will be slightly different length, and I don't want to get the spacers wrong... Once I have the length for the stubby Bosch ev14's I will be able to do those for very competitive prices. If anyone in Melbourne needs a set fitted give me a PM, it will help with more options for topfeed conversions.

Buy natural gas injectors because they are somehow better than new stainless body ethanol/methanol rated injectors? Right... Shame you didn't buy the 1400's through me, I could have re-tested them free of charge Gareth. I have noticed lately many tuners have no idea how to tune anything other than EV14's, Cihan (etuner) and Trent (Chequered) have had no issues setting the 1400's up, and they run beautifully in my Evo. What is your base fuel pressure, and what pressure is it on at idle? Try lowering the pressure for finer idle fuel control. More likely there is another issue, and your tuner is just blaming the injectors as usual... These and most modern injectors require decent voltage, if your car has a resistor pack it needs to be removed. What is the voltage at the injector out of interest?

It won't be the head gasket, cars just do that on short runs, as the oil hasn't heated enough to evaporate all the moisture.

I have a rebuilt set of 34 Brembo fronts here, with DBA 4000 disks near new. $800. Fitted under my 17's fine, I upgraded to 8pots.

Not with those little injectors.

I have had all kinds of tuning 'faults', that one included. My evo does it on cold start atm, I need to fatten up the cold start map but I will just be wasting fuel I guess. Spools the turbo extremely well though. The joys of not having to worry about knock. WB is the brand. http://www.wide-band.com/widebandproducts. Looks like the price went up $15 since I bought mine a couple of months ago. I got the tiny display to hide behind the clock.

Firstly, yes the WB comes shipped with sensor, box and display for $130us. No need to data log. Secondly, yes, a lean throttle enrichment will cause those exact symptoms.

I think we have a winner. lol.

$130us for a WB these days, shipped. Should be pretty easy to see if there is a lean spot on acceleration with one of them mounted in the exhaust. He might not see it as well on the tailpipe wideband.

Sounds like a lean pop as you accelerate, could be a simple tuning issue? The Fcon can be a difficult ecu to tune if you aren't familiar with it...

Actually, I don't like using the fuel reg line for the manifold pressure reading anyway, as that long hose you are fitting can slow the reg's reaction down. Also if it leaks it will lean out your engine. I prefer to use the front bung normally used for the stock boost gauge. You might need an adapter though, it's tiny. The BOV line is another you could use, who cares if that leaks. Make sure you put a cable tie around the hoses to the reg, they have been popping off a lot lately.

JE pistons don't cause the slap, the clearances the machinist picked determine that. If he felt you were going to thrash it, he will make the bore clearance larger to accommodate the expansion. No big deal, the twin plate drowns those noises out. lol

I'm running the stainless 1400 Xspurts in mine with no issues, with the stock rail. Might be worth a look if you plan to run ethanol. More important is what pump you are fitting, you will need to drill the vac generator inside the tank lid if you go much larger than stock. I had 70 psi base pressure after fitting the 460 Walbro, and the reg would do nothing. Make sure you cut and solder all the resistor pack wires together, or buy the Spoolinup dummy connector. All these injectors require you to bypass the resistor pack.

Drop your exhaust and see if boost comes on earlier. Could be a blocked cat, or the wastegate is leaking? Grab a heavy actuator from Hypergear, or buy a Turbosmart one if you are cashed up. Make sure there is around 5mm of wastegate preload on the puck.

Head off. Looks like you will need to learn how to do it yourself. Chalk it up to experience.

Just because it snapped coming on boost doesn't mean that's what killed it, the damage was done (not long) before the failure looking at the pics. How hard does he drive it? Would take a massive shock loading to snap that shaft...

Smaller inside? Mine doesn't flutter, even on 40 psi. The springs are replaceable, and they come slightly on the tight side from the factory. If your setup flutters slightly you could just ask them for a softer spring.

Tight budget, just tap an M5 grub screw into it, at least that way you can remove it if you don't like the way it drives... Otherwise the Turbosmart Kompact plumback is perfect to replace it.

All good, but a drag setup won't suit if you plan to drive the car on the road. Those of us with fuel heating issues will warn you will require a large adjustable speed pump to keep fuel temps under control. 3 Bosch pumps will look the part, but you can max 1000's with a single Walbro on factory lines.

One of his injectors had stopped working, after testing it I realised he hadn't cut the resistor pack off, one resistor had blown taking the power from that injector. The resistor pack was much hotter than usual. Obviously it runs fine on the Haltech without modification, but overloads the resistors. Goes to show the Haltech runs some great output drivers.

If upgrading the lines then by all means, but sometimes you need to work with what's there from the factory. My 6an return is fine running twin 255 Walbro's. If you can run 35psi at idle then your return is large enough, any larger is wasting cash. Large single pumps require massive lines on the feed side though, to stop cavitation.

Oh. That might explain things. I thought the entire setup was stock.

As I mentioned to Tao yesterday, Daz has made 500kw on a stock cooler and is heading for more. Not sure yet if he plans to upgrade his cooler this time around.

Sounds like you mixed up two coil plugs. If you had told me you just swapped the rocker gasket, I would have mentioned it before.
