T3 Turbo and Manifold Recomendation for Drifting

[Radial]

The cooling system is probably helped by being only an oil cooled turbo. Any more info on that manifold?

Yes... oil cooled turbo probably helps the cooling system... I'm considering adding an extra oil cooler, just because of missing that water-cooling. Just running the stock oil/water + aftermarket 20 row Air/oil cooler for now.....

Don't know much about that manifold really... as I bought it from a local dealer. I've just been told its made on the HKS factory. The manufacturing quality is excellent. It's is made of 304 steel (I like 304 better than 316, as it does not crack as easy).
As it's just delivered with the T3 Twin flange, I believe it's supposed to be mated with an IHI turbo or similar...as they use Twin-Scroll frequently.

Ok, since you bought it locally then there probably isn't a part number. A generic manifold by HKS would be reasonably priced which is what I would want. Some of the prices ive seen are way too pricey.

Well, I can tell you for sure that the HY35 Holset would not meet your goals. I expected spool at low RPM like you did with your RS-51... and I ended up with it reaching boost threshold at 3000 and major spool-up around 3600. I was surprised because a few people with eclipses had run them on their 2.0L 4 cylinders and had boost about 500-700rpm earlier than that. I suppose it might be something to do with the larger pulses coming out of the 4 cylinder... but I really don't know.

A garret GT3071R would be ideal for low RPM spool, but you would only be able to make about 400whp at the absolute most I would think, and the top end would be slightly choked off. A GTX3071R would be better, but those are even more expensive.

Whats your AFR readings?

You see.... I replaced my stock FPR with a quality Adjustable one last week. Adjusted the fuel-pressure to Stock settings and took a test; o2 readings increased from 10,5's to 11,5's. Response and powergains increased significantly.
The stock FPR was probably not working so well.

Happy with that result, I went for a trackday at a HUGE track with really grippy tarmac. But I was lacking waaaaay too much power to manage most of the turns on the track.
so I just stated to my self that I should try the rest of the day with some regular Racing and Time-laps instead (oh GOD its boring to do time laps)
Throug 10 miles of Time-laps, something happen though.....And I really don't know what happen, but powerlevels started to increase... especially around 3000rpm's. Power kicked in instantly at 3000, almost like the stock twins did.

At the end of the day, I managed smoooth drifting through almost the entire track, and transitient response (on-off throttle response) has switched from kinda laggy to become VERY good.



My theory is Increasing the AFR's made me more power..... and that the new turbo needed some break-in?? As it really is much quicker now, and I'm starting to get kind of pleased with the results.

anyone heard of a Journal bearing brake-in like that before? But it works very good now, 3'rd gear drifting is easy and boost is 12-14psi (my Manual BC cant stabilize pressure entirely)
There is a dyno a few miles away from my garage, really want to check out the results with a dyno.... will post the dyno if I get it there
