It'll be a 1.05.

Update! Fuel system is almost completed. - Aftermarket Industries SP 1200 using 2 of the possible 3 Walbro 460's. - Speedflow 200 series black braid hose. -10 all round with a -12 breather. - Had a fuel hat spun up to accept the factory rubber. (This is away getting machined up to accept the fittings ATM). - Ethanol sensor in the return line which has a bypass around it. The by pass has a 1 or 2 psi one way valve in it to push as much fuel through the sensor. - Hypertune rail which got annodised black. - Bosch 1700 cc injectors. - 3 X Fuelab 828 series (5 inch long element) fuel filters. 1 is a 40 Micron pre surge tank, the other 2 are 6 Micron in parallel post surge tank. Got the reground HKS V-Cam back. It started life as a 264 @ 8.7 mm. Duration at 50 thou was 222.xx. It's not a "270 ish" @ 10.25 mm. Duration at 50 thou is 229.54. The Unigroup "260" at 50 thou is 232.34, so a little more agro. That has 10.85 mm. The Base circle went from 32 to 30.1 mm on the modified V cam camshaft. Unigroup cam left, V cam right. Unigroup left, V cam right. Unigroup left, V cam right. You can see the different sizes of the nose between them. Totally different, not to mention all the oil gallery machining going on in there.

Nitto/HKS/JUN/Spool/Whatever says there bottom end is safe to "X"? If you throw a leg out of bed, how do you claim warranty?... Good luck! A turbocharger is no different. One of my -5's had shaft play like nothing else within 5,000 kms. Did I claim warranty? No. Were they operated out of what they were designed to do? Possibly!

Thing is, there are ways to measure it. Would you run a standard RB26 to 13,000 RPM, then when it dies jump up and down saying the engine is badly designed? Operate the turbo within it's parameters and you'll have no issue. How is that different to any other mechanical item?

The surge tank used to get scorching hot.

Wouldn't where you change be dictated by your power curve? What rpm do you nose over at?

Geoff, can you confirm any sort of update with the 8374. I haven't seen any "update/gen2/revised" from the get go? What exactly has been "updated"?

Brand new? The EFR range is almost 7 years old now.

Ain't no 26's around. Haha

Didn't really mention my car at all. Im back on Tuesday.

Won't fit with v cam being used. Not a big fan of them anyway TBH.

Nah. the world record car was on a hoist. There was a 32 without an engine and box in it. Heaps of finished engines all wrapped up.

I escaped without spending any money! Lol

So, I went here today.

Have you seen the dyno graphs floating around for these Tomei turds? They're absolute garbage. I'd rather spend money out of my own pocket than run free snails which are garbage.

No. Only the cam gears. Rest would be in a for sale thread on SAU.

Because twins? ?

There is very few Jap things on my car. Only Tomei thing is the stroker kit. IF it fails again I'll go bigger! Tomei turbo's won't find themselves on my car, however. First reason. They're twins. Second reason, they're journal bearing shit. Thirds reason, they're twins. ?

Tomei arms. Best place for them is the bin. Not sure why that shit is my build thread, but anyway. Haha

Double post

A car set up for and running an open T4 turbo from the brand they are dealers for (Precision) then they get a divided T4 turbo and put it on the same open manifold, somehow that turbo still makes >700whp and spools better than the Precision despite god knows what awesome stuff happens when the gases suddenly meet a brick shaped fork in it's path. Somewhat BS comparison.

Prob needs to be factored in with cam duration and a decent rear housing!

I suppose it depends on what dyno you throw it onto. What would be good is to see the exhaust gas pressure difference between a 0.92 and 1.05. You have a 79 lb/min turbo. Why choke it with a small ass end? Let it breathe!!!!! In AND out! For the record, the 1.05 AR ain't laggy AT ALL, especially if you have pulled off/come from "responsive twins" ?. Don't let the number scare you away.

Well that's a IWG version only (0.92). 1.05 and 1.45 ass ends are external gate which would make them the same cost to setup as choosing another brand (with however you decide to set it up).

6 boost manifold = $1,300 ish Fullrace manifold = ALOT more, depending on exchange rates. Twin 38 or 44 mm gates, $450 ish each. Depening on how you set up boost control. 1x3 port MAC valves or as crazy as 2 X 4 port MAC valves = $120 - $360 depending on which way you want to go. Braided lines (you'd have to have rocks in your head to run rubber). This ain't cheap. Well over $1,000 here in lines and fittings. Gets a bit out of hand when running lines to the top and bottom of the diaphragm with duel 4 port MAC valves. Water and oil lines = Not quite sure. Haven't added that up. IWG EFR would be a fair bit cheaper. No gates and not as much plumbing pain with the lines. No fab work with plumbing the gate pipes back in. That itself is an expansive exercise.
