Thats the point of what I'm doing. 

 

With that 2.0 CBD you retain the strength with sleeving, and then convert to dual thrust.

 

go to 2.2L 96MM sleeve rather than the 2.5 99 (or 99.5 - 100 depending on your route), and hiff in a 2.5L crank. 

 

You get to keep for the most part the RPM's of a smaller 2.0 motor while having some of the torque or the 2.5. It's a good middle ground that not many people in NZ have caught onto yet, and I'm gonna run with it and see how far I can push it. 

 

Closed deck, sleeved and forged internals could see me well. 

 

So what sort of turbo would you be running?

 

I'm currently stuck between a few options, and am open to further suggestions (from I have discovered)...

- TD05HRA-16G6C/10.5T (EVO 9 RS turbo)

- Garrett GTX3071R Gen II (EVO 10 turbo upgrade - good for 550hp apparently)

- Garrett G25-550

Ideally something that's making full boost at around 3000-3500rpm.

- Garrett G25-550

I don't know what I'll be running. However, it won't be any of those.

Here's why.

The td05's are old as hell technology. They're not a bad turbo, you can just do much better.

GTX3071R is a great turbo. Better off getting a Holset or turbo from Steve Murch for the price you pay as Garrett's are EXPENSIVE (for what you get).

The Garrett 550 turbo looks to be awesome, but once again, same thing as the GTX3071R. Expensive for what you get and similar results can be had from a much cheaper holset based turbo from Murch.

Now I'm not sure what turbo I'll get yet. My build is some time off, but likely I'll either go down the range of EFR's or I will use one of murches new in-house turbos.

BorgWarner EFR series

Cons.

They're god awful expensive.
If you nuke it, good luck getting it rebuilt or fixed.
They're VERY long. So hard to get in the right spot.

PROS:

They're bloody amazing with spool characteristics.
Built in BOV, wastegate and boost controller. Means much less money spent on extra fabrication work and kinda levels the price difference between a Garrett and holset tbh.
All round VERY good turbos when done properly.


Holset/Steve Murch turbos

Conns:
Big turbos. Hard to fit nicely.
A lot of fakes out there (holset). Buy genuine from Murch direct.
No integrated bov or wastegate. Lots of fab (like Garrett).
Holsets can be laggier than the others unless you're twinscroll. This is where Holsets come into their stride.

Pros:
CHEAP. CHEAP. CHEAP!
As long as you've explained your build properly and what you want from the car, Murch can give you exactly or near what you need.
Very sharp pricing on rebuilding turbo or servicing etc.
NZ made and assembled turbos.

That's VERY basic but that's why I'd sway to either of these two, rather than Garrett or an old school TD turbo.

Take your pick, but make sure you really keep your mind open and don't for the love of God pick something just because of its brand name.

Liking the sound of Holset/Steve Murch vs the others, as I plan on going Twin Scroll. Hopefully I can fit it in a twisted location in a BE engine bay, with top mount lol. Could even do a bottom mount!

Was just using the Garretts as an example. I agree that they're expensive, but they're pretty dang good for what you get. More so paying for the Garrett name though.

I'm not afraid of the extra fab work needed for an external wastegate - I was gonna go down that path anyway (better boost control). I'll be running a top mount intercooler, for Sleeper & Stealth status, so I can probably get away with a bolt on BOV (speed density too). Probably get GFB stuff, unless there's a local NZ company that makes stuff like wastegates, BOVs and boost controllers etcetera.

 

I know I'll be making my build expensive lol - but I wanna do it properly. I'm a perfectionist, and this is something I'd love to make so!

If you're wanting to go twin scroll I don't believe the G25 series has twin scroll options yet (check I could be wrong), but do look amazing aerodynamically from what I've read.

Have a chat to Tony at DTech. They’re not huge fans of the HRC turbo’s. They do alright but under perform on Subaru’s compared to other brands like Mitsi’s where they really shine.

 

Garrett's and EFR’s are expensive but they behave well.

 

@Jono24 has a Holset in his 3rd gen so could get some tips from him for fitment if you do go that route

If you want to keep the top mount you need to read through Boons v7 thread. The engine bay size is similar and i believe it was a tight fit with single scroll.

The hard part about top mount + twin scroll is finding space for the waste gate/s. This may be possible with an efr with integrated gates.

Not to be a downer, but I don't think it will work. I initially intended to try to keep the top mount (I had a very nice hyper flow top mount too) but it was too much hard work.

Did we ever see a retune of evowrx/furzes car after the valve springs were replaced?

I thought clint's brothers car was on a gt30 and also made similar power?

I haven't heard of a stock long block of the v7-10 era making anymore than 300kw (in NZ).

One other thing, holsets aren't water cooled typically (some hx40s are). This will add to your oil temp significantly.

Don't think so. Pretty sure it's moved onto someone else now. Dairusire will know all the details.

 

There was that wagon one DTech did, can't remember the guys name but was in Hamilton then moved down to CHCH, which they apparently had a heap of trouble with as it just wouldn't make the power expected of it.

 

Oil temps are definitely worth considering. The one plus for them is cheap and easy rebuilds, other brands you're expected to buy a new supercore at a minimum.

 

Before getting the 3071 Tony had suggested I grab an AirWerks turbo rather than the HRC if wanting a cheap well performing turbo. Oil cooled only, like the Holset.

There’s a heap of variation out there but the later ones borrow Some tech from the EFR’s

This is the one you’d probably compare to a HRC32/2. Can go cheaper again and get the non-enhanced older versions.

Yep Furze still owns it and D tech originally only made 265kw on 98.

SAS did a great job and got 275kw from it on 98 and 302kw on e85. The limiting factor obviously being a factory bottom end and the 1000cc injectors running out of flow thanks to ethanol.

I'm not sure if you pay attention to YouTubers who do car content - Adam LZ has a G25-550 on his SR20 S13 drift car, and that thing is mental! Hence why I mention it.

Probably the only Garrett turbo I'd consider, from what everyone else is saying.

 

Liking all this discussion too! I'm learning quite a bit! Thanks fellas! :)

The 275kw was after the upgraded valve springs and 22lb of boost yea? If the bottom was built you think it would've crossed 300kw?

 

My build has been complete and has been at the tuner for couple of weeks. The car will be on dyno on Monday. But I am using the same turbo which is in question (hrc35/2) here. Mine is a 2.1 stroker forged and doweled. I am planning to run 28lb of boost to get me over the 300kw range. As Drews car I have upgraded the valve springs too. Here's hoping for 300kw. If not I will change the turbo to the airwerks 7670 as it's a poor man's efr 7670. The only reason I went with holset is due to the rebuild factor and that it should spool up better compared to the airwerks as the holsets turbine housing design is pretty darn good.

It's actually on the same (if not a little lower) boost, but in general I think it could've got there before without the springs. Jason is just a very good tuner.

If it was built and had larger fuel injectors it by far would've gone above it. It was wanting to as far as the torque was concerned, and that was dialed back.

Who is doing your tuning?

That's good to hear. My limit will probably the injectors (912cc) and the fuel pump (dw65c). Fuel will be gull force 10 as it is better when going above 25psi.

 

Hitech motorsport is doing my tuning. However not on the stock ecu. I have gone the haltech way :). They generally don't do many walk ins as their clients are targa based. From what I have spoken to the owner, he is very switched on and lines up with all the research I have done as well.

Started the rear view camera installation this past weekend. Wired the main video feed from the front to the rear.

 

Tested the unit and all works well.

 

Now need to find a way to still mount the camera and just reconnect everything

Sexy! I need me some headers like those sometime!

 

Also, Z436 - that's a pretty small oil filter! I've always run a slightly larger Z79AST on my 02 Legacy, vs the Z79X/Z495 that is listed.

 

Edit: checked the Ryco listings - Z436 is what is listed for these cars. I'd advise going the Z436ST - they have a better filter in them, and are a long life filter. Also have a grippy surface on them, so don't need a tool to loosen them!

Oh awesome thanks for the Info on the Filter I will chang it for that next oil change

 

Ah sweet will check on the turbo number

Getting ready to spend a fair amount of money on the mighty S401!

 

- Set of MCA coilovers

- Whiteline all the suspension bushings, and other little things

- Znoelli DDS Rotors

- Good set of street pads (open to suggestions here... or I'll just ring RaceBrakes)

- Cert

 

Should be good once it's all done!

That's all I'm gonna do for the year I think. Depending on money, and if I decide to travel or not, I might upgrade all the diffs in the transmission/car too.
