Awesome powerful turbo
However, the anti-surge isn't very well designed as there is only one layer of holes, which does not contribute to creating the Venturi effect very much, decreasing the effectiveness of anti-surge

Look at the HKS T04Z turbo for a beautiful anti-surge design:

It's too early to tell wether the kit is worth the cash or not. If it spools the same as a 35R and doesn't make anymore hp, IMO it isn't worth it at all. But if it spools noticeably better than a 35R and puts down the same if not more hp, IMO it will be a great kit. So hopefully we can get some dyno charts of this kit on a STI soon and see how well it performs.

Personally, I think that thread is a joke. Its funny to see quite a few people sold on something like that without even seeing one teeny tiny bit of factual information. The only thing I saw in that entire thread was it's a twinscroll setup and its a 70lb/min turbo.

Get real people. Before I gave one penny to APS, I would demand dyno numbers, data logs, compressor graphs, etc. At least some sort of information for me to make a logical decision as to wether I would want to give them my $3000. But hey, it's your money.

But that's why I never really liked APS products....their products never seem to back up what they say.

i run an SR40 in my car as well as an APS FMIC, DP, Intake, and related parts id say they do a pretty good job the turbo spools faster than stock and i am able to get down the track in pretty descent time. Aps parts fit perfect and have an OEM appearance.

now that all that is said it doesnt prove this product, but APS's recently released header has spoken for its self, and many of their other parts have done the same.

APS doesn't make the turbo.. they most likely use a garrett GT core and do some modification to it

Using basic automotive engineering principles you can see that the kit is going to perform... the complete engine flow capability is what gets you the power:
intake/exhaust pipework, IC, turbo, headwork, tuning etc. is what gets you the results


70lb max flow compressor tells you roughly the max HP range it can provide
I agree it will be nice to know the full details
turbine wheel size & trim, compressor spec etc..
Maybe APS will provide more technical information when they actually release it...

as far as what I get from this forum itself is that dyno numbers are going to mean squat anyway... as there is no stable datum to compare the figures to
unless it is compared on the same dyno, with the same corrections for temp, and barometric pressure
Not only that,with the dyno graph you don't usually get the full details of the complete setup spec eg.
type of headers, size of piping, extent of head work/cam spec.... or even whether they an air filter on the compressor inlet


Based on seeing the pics of the APS twin scroll header rotated setup, and knowing that it also fits with the APS FMIC's (which are proven to perfrom well) and the fact that they have a 70lb turbine assembly to go with....

If I was looking for 500wHP result I would interested to buy a TSR70 kit

Given APS's handling of a number of my friends when they experienced issues with APS parts, I probably wouldn't put it on my car, even if they gave it to me. If nothing else, at least it may be a hint of more twin scroll units to come from more customer oriented companies.

To me it depends on the price. You can do a lot of custom work on an off the shelf turbo including twin scroll for $5000.

yeah i was wondering about this also i only see one layer of holes myself albiet smaller holes, but still only one row, the outerholes appear to be for mounting bolts.

I know where you're coming from, but we have seen similar turbos. This turbo is very similar to a GT35R, but with a larger compressor wheel and twin-scroll input. Even if the twin-scroll didn't make it spool faster than a GT35R, it's almost guaranteed to hit a higher power number. How much? I don't know. However, for any APS header owner, this gives a viable solution to go rotated and not waste the header they own.

So...ANYBODY with an APS header who wanted a GT35R setup, but didn't want to waste their money they spent on their header shouldn't be afraid of this setup REGARDLESS of the final results. At the end of the day, you may find the twin-scroll did NOTHING to improve flow and spool and the larger Garrett turbo had slightly slower spool and slightly higher top-end #'s than a GT35R. Although as assumption, it's definitely logical enough to bank on.

Think of the new Helix RR500 turbo coming out. It's basically a 20g w/ an 8cm housing. People can speculate all day long about what it does in power. The one thing we know is with the larger housing, it should flow more and probably spool slower. If the design is good enough, it will spool the same and hit higher #'s to a standard 20g, but if you bought it expecting the first of the two assumptions, you probably wouldn't be dissapointed.

I guess the point I'm making is APS is NOT re-inventing the wheel. We know rotated setups work. We know garret turbos work. We know twin-scroll setups work from the JDM setups. If you went into buying this setup as a slightly better GT35R setup, you shouldn't be dissapointed.

100% correct...............mounting bolts don't count as anti surge ports.............

GT40 kit is where its at. We will never catch up to the other guys untill we all see this. If you want a Show n go car it is a great kit, but why spend that much money and not get the biggest kit?

Because there is a certain point with turbo sizing where a larger turbo means less useable power/torque across the entire power operating range, EG, little point in having a turbo if the operation is limited to between 5500 to 8000 rpm as an example.

when would you get full boost with a gt40r on a fully built block and heads.

The GT40R has been said to hit full boost around 5000rpms on a 2.5L, so for those who are running an 8000+ redline then that is plenty of usable power. In case you werent aware the GT40R has a T4 Twinscroll entry turbine housing.
