Two Steps Closer

... to turbocharging the Charmant. Just bought these off Ebay a couple of minutes ago.

These feed & drain lines were said to fit T3, T4, T04 and T61 turbos. Considering my plan of using T25 or T28, i hope they'll fit. If not, i'm sure only minor mods are needed. (update 1-Jun-2011, see below)

Now, these are different case. They have to work or i'll be left with very expensive paper weights.

RX7 460cc/min injectors with PN195500-1350. It's not about their dimension as i'm pretty sure they will sit on the stock injectors' location neatly, it's about their impedance. My stock injectors are high-impedance, or saturated. I prefer my replacement ones also saturated. Not only because i'd save cost by not having to buy a resistor pack, i read that due to the lower drive current, they should last longer than the peak-n-hold type. Besides, my Megasquirt ECU is not ready for peak-n-holds as there's no flyback driver circuit in it.

The problem is PN195500-1350 doesn't mean they're saturated. Curiously, you can find both type under the same part number. Here you go:

The only way to be sure is by measuring the resistance myself and that's of course impossible to do before they reach Indonesia. Other than that, they don't come with the connectors so hopefully the stock ones fit. Hence, here i am crossing my fingers hoping that everything went well.

Why 460cc/min when 7MGE injectors are high impedance, flows 315 cc/min, much cheaper and no-brainers for my injector upgrade? Simply because i'm preparing for at least 10-14 psi of boost and i'm not sure 315cc will be sufficient. I did a number of research on the internet as usual before and somewhere along read that a 4AGZE injectors at 365 cc/min would be at 80% duty cycle at 8 psi! Thus, i'm playing safe here. I prefer to pay extra to be sure that they're up to the job.

Unfortunately looks like i bought the wrong kit. Since i'm going with TD04H turbo, this link from stealthmodeperformance.com tells me that the drain and feed line won't fit. It's about the threads on the oil inlet and the drain flange bolt hole spacing. Copied from the link:

T3 kit uses a 1/8 thread size for the oil inlet. The drain flange from center to center mounting bolts measures 50.8 mm.

14B (tdo4h) uses a M8x1.25 thread size for the oil inlet. The drain flange from center to center mounting bolts measures 38mm. This kit does not come with the mounting bolts to bolt the drain flange onto the turbo. There are many different sizes used on different variations of the 14B. That is why I don't provide them, but can easily be found at any hardware store.

I can't really confirm this until i got the turbo delivered. Oh well, another trip to the machine shop is scheduled then.
