My understanding is white smoke indicates burning water/coolant. "Blue" smoke (which is fairly white) indicates burning oil. But it sounds more like an oil build up after decent driving than a coolant issue (blow by etc.) Breathers still plumbed in to the intake?

I know right. I was thinking they would do 180-190wkw but was wondering if anyone has seen any nz examples. Surely there must be a few around.

What are the factory td04 good for? (with all the required supporting mods) Americans seem to suggest they are just about good for 300whp which is near 220kw, more than I thought they would do

Sorry, i'm thinking in a pressurized pipe (post turbo). You are right, a leak post maf - pre turbo should cause it to run leaner (which to me those values don't suggest, but I could be reading it wrong)

If it's removing fuel (which to me a negative % correction looks like it is), that means it's reading rich. An inlet leak after the maf would create a rich environment. I know nothing about the software you are using, so could be reading it wrong

I've had 2 cars tuned with vf22 and yellows and neither run out of injector, both 220-230wkw range. If you are stuck on the factory top feed idea then yea, id try get factory top feed rails and make an adapter to bolt them to the phase 1 manifold. Wouldn't you also need collars for the phase 1 manifold or similar due to the different injector sizes.

I would have thought yellow side feeds will support more than what a vf30 can flow. So unless you are future proofing, stick with yellows. These should fit, sell the other 2 and your pinks. https://www.trademe.co.nz/motors/car-parts-accessories/performance/other/listing-1745471863.htm?rsqid=79f83d2abe744097ba1e5dd1a017b24d

New inter cooler in and did some testing on the weekend. Pressure drop across the core is basically the same as running a straight pipe. It needed roughly 15% less waste gate duty to make the same boost, and afrs were leaner on high boost. Slight improvement and a step in the right direction.

Agreed. Mine went through cert with a small front mount which bolted to the bumper bar. You could put the bumper iron back in with a slightly smaller front mount for the cert. Shameless plug here, I do have a 550x230x65 core for sale for $100 which should fit.

Back on topic. I'm annoyed the power band is so high, yet so restricted. It's like the worst of both worlds I've ordered a 500x300x100 ITL intercooler and joiners to suit. Once that turns up I'll do another open loop boost test to check the pressure drop across the new core. I'm not expecting miraculous results from a core alone, and won't go back on the dyno unless there are significant changes to AFR/knock. I've got a seized bl/bp engine being picked up this week (I may have a full twin scroll conversion for sale if a friend doesn't want it), unsure what condition the heads are in but will pull apart and have a look. If they are ok they'll still need sti cams, porting and some aftermarket springs. In theory the avcs should be able to bring the power on earlier, plus remove any doubt around my existing cams and dial in. Slight problem with quad avcs is the required outputs will need the current idle control output, so I'd need a different icv or remove it all together (I'd need a phase 2 manifold anyway and I believe the v7-9 have a icv that would suit). When the current engine comes out, we'll check the dial in and measure the cams to see if we can find any more clues.

Pump must be duty or voltage controlled then, to provide the progressive control? Most of the feedback I've read suggests the aem flow sensor will evently die and that the aquamist sensors are the only flow meters that survive methonal long term.

Ahh I see, looks like it has an injector type set up which I assume is pwm control from the AEM device. Not a bad way to do it, from what I have read the progressive is the best way to do it. That injector thing negates the need for the pro meth solenoid, I thought the kit just had a normal check valve. I see the kit has the failsafe flow meter? I would be interested to see what the failsafe outputs, I assume its a frequency that the link could also read. Yea my failsafe is just pressure, basically it should be between 150-190psi once turned on. If its outside of that, the boost table doesn't switch to the higher boost setting. I use to have my pump as the progressive control, and an on/off solenoid. It had a fairly linear pressure but I wasn't sure of the volume. Now with the pump on full time and progressive injector from the solenoid it's 180psi ish from the moment the solenoid opens, again I can't be sure of the volume of flow. The idea is now with the higher pressure it atomizes better, where as before it didn't at lower pump pressure/duty.

I Believe all the pumps are pretty much the same thing with minor brand specific difference but could be wrong, I've only seen the devils own one. I thought the pumps have an internal bypass valve at a certain pressure. You can run the pumps off PWM using a SSR to make it progressive. Not sure how else the AEM set up would control it. I'd rather a solenoid than a check valve

I don't know what solenoid (if any) that set up comes with but would recommend a pro meth solenoid. They can be control directly by the link and is low enough current to not require a SSR or external pwm control. Pump starts at 4psi or so, solenoid progressively opens mapped on injector duty (from memory the ideal mix of 50/50 water meth to fuel is 15-20%). much the same as doing it map vs revs.

It's a bit of a mixture of parts. Devils own pump and nozzles, pro meth pwm solenoid controlled by the link, rest of the tank, lines fittings from ali/ebay etc. Fail safe is a bit average but is hooked into the link (pressure sensor only, which isn't as good as a flow sensor imo, but it seems you can't get reliable flow meters for methanol). I've got knock control set up in the link as a second fail safe

I didn't know there was any difference in the dipstick, obviously the levels read differently? do you know if the SS dipstick reads high or low in a TS sump? I changed to the TS sump, baffle/windage plate, bl/bp headers, pick up and added a SAS baffle plate. Hardest part is removing the rear sump bolts and putting in the up pipe, both of which need the engine to be jacked up slightly. If I didn't have my Garrett and external waste gate already, I also would have gone with a borgwarner set up as boon described. I'd enquire about a SAS baffle plate instead, looking at it I assume it would work with both a single scroll and twin scroll sump.

If I was after a fast spooling setup I'd go for a factory sti twinscroll exhaust and turbo and spray water meth pre turbo (which in theory chemically alters the compressor map to act like a larger turbo). Second option would be bl/bp twinscroll with a bolt on aftermarket turbo. Bl/bp twinscroll headers and sump can be had for $300 now days and the bolt on turbos arent much more than the td05 option which you are talking about. (Which I'm skeptical would make the power suggested)

In checking my ebay history, I noticed that turbine housing is 0.82 not 0.72, so slightly larger than originally stated. Have changed the original post.

The vf38 flange? Kinugawa off ebay as I couldn't find one in NZ https://www.ebay.com/itm/Kinugawa-Turbo-Flange-SUBARU-Liberty-Legacy-VF38-VF44-Turbine-Inlet-Ex-Manifold/273191220183?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2057872.m2749.l2649 I like the sound of these plans

Water/meth is said to have similar effects to ethanol, more det resistant and cooler IATs, so adds some safety. Although there are more risks with W/M than ethanol (in the event of blockages/leaks) To hard basket, mainly the fuel system upgrade required and nowhere local for me to get it. My solution was water meth and more boost. If i need to upgrade my injectors I'll be getting some that are ethanol compatible. The target is "only" 300kw with a decent torque curve so shouldn't need it.

You think based on those back pressure readings it would be an exhaust housing restriction? I was thinking along the lines that with the turbo producing 34psi, that pre turbine egbp of 35psi is pretty good considering.

From the Waikato area. Will head up to night wars or similar at some stage. Interesting... I think you could be on the money with the cams, it doesn't really have cam lump at idle. Nil porting as far as I am aware. These are just the heads that the long block was built with, I assumed they would make the power with supporting mods. I do have a bl/bp engine lined up, but its seized so unsure of condition of the heads (fingers crossed they are ok). I'm not concerned with the high boost on 98, its what I asked for and that is with water/meth.

It's one of the ITL cores, and it seems to cools great. IATs are better than the old (same size unknown brand) core. The persons who said the IC was to thin - his theory was that the flow area was to small and is causing a restriction, and said he and mates had run into similar power restrictions which turned out to be the thin IC core. Yea 0.72 TS is smaller than 0.86 SS, although I believe TS and SS housing sizes aren't directly comparable. The 0.72 TS housing probably more similar to a 0.63 SS housing. I'm thinking the similar around heads, some avcs heads (either single or twin) could help bring the boost on earlier as well as flow. I'm considering bp/bl heads and adding sti or aftermarket cams, and some decent springs. But I need to test another IC core first, and then pull the heads off for a look and measure up the current cams. I was hoping for better spool going TS and at least 300kw. I wouldn't care about the power figure if it had a punchy early-mid range, but at the moment is fairly laggy as well as torque tapping off. Thankfully with the 6sp once you are in the power it stays there.

Yea, fair point, I had thought of splitting it out but dyno thread gets more action . Single 38mm wastegate just before the up pipe. I did consider twin or larger wastegate but knew i was going to be running high boost and gambled it wouldn't have boost creep, which it doesn't. I've only really got photos in the build, none of it completed: Intercooler is coming off this weekend to test the psi drop across a different core so can get a photo of the IC set up then. It's by no means pretty, but it works (same with the whole car really)

I used to do build threads, but I never updated etc. so haven't bothered with this car. Will post more details and have a discussion in the other thread.
