Default Twin Turbo 2.5RS pics...

Took this pictures at local car show I was in, without further ado here they are...
(Stole this pic from iv30, because I forgot to get a outside shot)
Outside:

Engine 1:

Engine 2:

Under car 1:

Under car 2:

Under car 3:

Under car 4:

Wheels:

Now what do I know about this car? Using a Tec-2 for engine mangement. Owner said its running rich right now, but runs good. Both turbos are T-25's. Huge FMIC. Stock injectors (from what I could see). P1's, Big brakes. Also extra pulley is for the dry sump for oil (?? I think I heard that right ) I asked if this would be a kit, right now they don't know, but if it was it would be expensive he said.


Here is the owner info:

Where is the intake?

Looks like the turbo is hanging right off the exhaust ports. Yeesh.. Wonder what throttle response is like on that car. Also looks like the intercooler feeds bottom up, but I can't really tell.. Small endtanks looks like.. Pressurized on both left and right sides?? Then fed through passenger side pipe to throttle..

Doesn't look like a Vishnu kit, can't see the crank sensor in the currenly popular location.. Where's the fuel pressure riser???

Hahaha, no cats, and that looks like the MRT Y pipe...

and lastly, mmhmmm, dry sump oil systemmm.. *drool*

Oh that reminds me, he said the intake was fed by the brake ducts. Also I'm pretty sure its not a Vishnue kit, because they had their own Electromotive (makers of Tec-2) Banner at their booth.

OMG That looks good.. But the turbo hangs down so low.. might get caught on something. Any idea if the engine is still stock?

Also wouldn't it be better if there was one big turbo and one small turbo?

Dry sump? Then what's that big, um, oil pan looking thing?

Also, was there a separate display for the metal shavings from second gear?

Seriously--the one thing a turbo 2.5 doesn't need is more low end torque. Maybe a heavier Legacy or SVX (or S4 ) needs two tiny turbos, but it seems like a lot of needless complication for a 2800lb coupe.

I'm guessing that thing on the far right of the engine with the big pulley is the oil pump. Gonna have to push the oil, because it isn't going to drain out of the turbos - they are at the lowest point of the system.

Plus the oil and water hoses are run right up next to the exhaust side of the turbo, at least on the passenger side. Not to mention just hanging down there. No off-roading for this one!

Even on the street, would feel better about a skid plate under there. Look at the damage to the front lip.

And there should probably be 2 EGT gauges though the one that is in there is after the turbo, a lot of the heat would already be shed, so I am not sure how good a reading you'll get.

Interesting packaging, though - I bet it is wicked fast.

looks like they need to jet-hot those intake pipes before they completely rust through.

the low position of the turbo's is very scary, a little after I first got my car, there was a large rock in the middle of the road, and I hit it, it would have ripped the passenger side turbo straight in two if it were there (luckily I didn't go over it right in the middle or my oil pan would have been gone)

however very innovative, good work to the shop.

First twin-turbo RS i've seen, and thats some serious custom modification to get all that stuff to work.

Anyone notice the center exit exhaust in the rear of the car?!

Lots of chopping on the front of the bumper to get that HUGE FMIC in there.

I wanna know what kind of internal work he's got done to it.

I don't think he has any internal work, but if you guys are really curious his email address is up there.

I have seen this car in thier shop when they were building it. They do lots of custom turbo work, mainly VW's. It looked like a really nice setup. The tecII is not a vishnu setup. The two intakes are in the corners of the bumper. The bumper has been modified to fit the big inter cooler (light weight supports ect.). There was no internal work done to the engine when i saw it last.

From what I understand, Cobb did a twin setup something like this as well, though I think he lifted te turbos a bit more.

That which is pictured is VERY near the design I posted about like a year or so ago. I was planning on making a heavy-framed skid plate to go along with it, so that no damage would come to the turbos, though. Put some louvering in it and you can ventilate some air into/out of there and keep the temp's a bit down.

My only delimma over the whole thing (other then the expense of two nice turbos) was about feeding the oil back up into the pan, which he solved with that extra oil sump setup. Very nice.

or you can use two Aerodyne turbos and don't have to worry about oil feed/return lines but it'll be even more expensive.

The setup looks like it was well done, but it has turned it into a mostly show car, as those turbos are way closer to the ground than I would be comfortable driving around town with, and forget and minor off-roading. I hope the piping is replaced before it fully decomposes as well

The quality looks top notch and it does show quite well.

I think there is a better design as far as where to put the turbos and such. Hopefully pictures of this will be available soon...

Aaron

I agree Aaron... I think we will see some pics of a different, cleaner setup soon too....

I still think a heavily-framed skidplate would make this a fine city-driver. Just a 3/4" square x 3/16" thick steel tubing frame with maybe a 1/8" piece of sheet metal bolted/welded to it to protect those turbos. I'd have no problem driving around town like that, but definitely not off-road (not like I will with my car anyways unless it's very minor off-road).

One other thing to remeber guys, is I took the pictures at a angle pointing up. They do hang low yes, BUT they look like they hang even lower in the pictures.

It isn't the angle you took them at that puts them BELOW the oil pan.

All right here's what the facts about the car, in a reply via e-mail:


"It's running T25s which are the same ones used on the 300Z TT's. Right now
it's at 10psi and that is achieved by 1500rpms. Needless to say, this car
has no lag. It's also running Electromotive TEC II stand-alone management.
Our customer already has a new diff which we're welding up so we can put the
car on our dyne and tune the TEC II. As of right now, it has a stock bottom
end. Our customer already has plans of a built bottom end and larger turbos.
The car is also running our FMIC and 3" exhaust.

No time slips yet. We need to dial it in first.

It's incredibly reliable-he drives it on the street all the time."


Pretty cool, and he said there is even more stuff about it on the web sit.
