Post Twin Turbo Kits???

A friend of mine was out on Front Street in Philly Saturday night and met a dude with an MY99 that had a twin turbo kit. No kidding. He said this dude has tried to come on and talk to people about it and nobody ever believes him when he tells them he has a twin turbo setup... Where oh Where can one of these setups be found???

Thanks

That was me your freind was talking to, and no I do not have the twin turbo in my car yet. I have money down on a kit but I do not have it yet. It is still in development, I do not know when it will be done. Maybe some time next month.

I think that's funny, too. The 2.5 had plenty of juice in the RS. We get a WRX, with 227 hp that goes 0-60 in less than six seconds, and we're chasing more.

Twin turbos for the Rex, manual boost gauges, bigger ball bearing turbos.

I, personally, will be leaving my powertrain stock, except for the "sound mod." Considering I'll be gaining almost 70 hp in a car just about the same weight as my Legacy GT wagon, I imagine I'll be happy.

I know that some of it is just that "Spinal Tap" syndrome. Eleven...it's one more. Some folks just want to have the fastest car out there. Heck, I'm sure that if the STi comes, people will be modding that one.

Viper owners head off to Hennessey, Vette owners head off to Callaway, while Porsche guys write checks to Ruf.

This hobby/car love thing is madness, y'all, madness! Sure is fun, though.

We will have a twin turbo kit available in June. I have to finish off other work fist which will give me time to iron out the details on the twin turbo.

are these kits going to be sequential? what would be the point in going non-sequential twin turbo? just playing devils advocate here but if twin turbo is so great why do all the supra guys go to single turbo?

Liquid Calm -- Are you sure it was you. The guy my friend talked to showed him the kit and it was already on the car. He also said the car had dual exhaust and a ton of stickers covering his car. My friend was a big dude with blondish hair and a blue and white (racing stripes) mustang....

Hey Liquid Calm,

Haven't talked to you in a while. When I read the first message, I was saying to myself, "Damn it, Shawn didn't tell me he had the kit yet". You still have my number right? When you do have the kit in, give me a call. Maybe we can go to the track and see how that baby run. Forget Philly! I haven't been up there for a good while now. It's way too hot anyway and it's gotten way out of hand.

Hit me up with email or a PM. I want to discuss details on what's the deal with your twin turbo kit. I was hoping you got it around xmas like you were supposed to have gotten it. I look up to your patience. Well, good luck in June and tell wifelady I said 'Hi'.


Rubasu,

From what everyone knows on this board, ASR are the only ones attempting to sell a twin turbo setup. As you can see above, it is scheduled to be out sometime after May. Either the guy you talked to thought he saw a twin turbo kit, he actually saw one that was custom made by someone we arent' aware of or he's lying. Talked to him again to be sure and give us more details if you can. What color was the car with the twin turbo kit? Is the guy on the 'I' club? I know Liquid Calm's car color and the color of the decals/stripes on it. You can't miss it. I think your friend is talking about him.

The supra guys go single because it is cheaper -- twins run easily $7-8k while a single is $4k. But upgraded twins look really good and is definitely show car material. Performance-wise, they can be very similar.

For the subie, twins will likely be parallel. It takes a lot of programming and plumbing to make a sequential system -- you need extra actuators and valves to allow #2 to come on, and you need the ECM to be programmed to open/close the valves to allow #2 to come online. It is so complex that there are no aftermarket sequential setups for the supra -- they are all parallel (although the stock supra is sequential).

I have heard that a single turbo spools faster and is better at top end. One thing is for sure, a single is more effiecent(?) than twins. I have even heard of triples on a Supra.

One cannot generalize whether a single spools faster than twins. It all depends upon what turbos you are comparing -- speaking in supra parlance, a small single such as a T60/61/63 with a low a/r ratio will spool much faster than, for example, HKS2835s. On the other hand, a large turbo with a large a/r ratio, such as a Greddy T-88 will spool slower than the HKS twins. If you consider that a well-tuned supra with HKS2835s can put down in excess of 650rwhp, and compare that to say, a T66, the T66 with .81 or .96 a/r housing can put down close to that amount, and outspool the twins by (at most) a few 100 rpms.

what you said earlier tho boostit was not true. not true at all. if you speak to any of the high horse powered low 1/4s supra guys they all have certain things in common
1. a very high budget
2. a single turbo

i know of a guy with 750 horses to the wheels, single turbo. i heard of a guy at a drag race that runs his bad boy against bikes!!!! damn i thought that was crazy. from what i know he had an amazing tranny, and a huge ass turbo, and of course could no longer run on "normal" gas. but from what i hear no one (silvia/300zx, supra TT) keeps the TT setup. you can find ways to reduce the turbo lag of a big turbo.

NickSTi:

I am not sure what you think is not true. If it is cost, the $4k and $7-8k is simply for the single vs. twin turbos, only. Fuel, electronics, upgraded intercooler, etc. will run another $7-12k (plus install and tuning), regardless of whether one goes single or twins.

And most people run singles because it is cheaper. The hks twins easily put out >600 rwhp -- on par with T66s. In the upgraded turbo supra world, many people are now going with smaller turbos -- T60, 61, 63 and 64, which cost 1/2 the price of hks twins, but are putting out close to 600rwhp and spool up at almost the stocker rate.

As to power, the high hp turbos are not limited to singles -- there are people with twins of various sizes putting out in excess of 800rwhp, as well as single turbos that put out in excess of 800 rwhp (e.g. T88s). It is simply easier to install and maintain one turbo than two when participating in racing events -- easier to swap out one housing than two when drag racing, or replacing a blown turbo.

And as to lag -- regardless of whether medium-large twins or a large single, one still needs to spool up the turbo(s), and you either have to split the exhaust gases to two turbos or one larger one, so spool-up time will not necessarily be significant between two turbos that ultimately provide similar rwhp.

Rubasu,
I had a kit on order from AMR (Andrew Nam)
He is a real nice guy and is putting alot of time into making sure the kit runs right. It will be a real nice kit when he is done.
The person with the OBS running turbo and NOS is Kevin Thomas he is a real cool guy and his car is crazy fast.
What kind of car do you have? RS or WRX look for me the next time you are down there. I do not have my RS any more (RIP) but I will have a WR Blue WRX the next time I am down there.

I was saying that I have heard that a single turbo will spool faster and make more power at the same time. I really don't see how this can be. I realize a lot depends on the size of the turbo. I always thought you had either a quick spool or high top end power. You get the best balance. Twin Turbos, I thought, spooled fast and had the high top end. I do understand that a twin turbo on a four cylinder is not practical because they do not creat enough air flow. It is also more expensive.
