You're not looking close enough, you can just seebpart of the housing for the second turbo under the top one. Looks like he had 1+4 into the top one and 2+3 into the bottom one. Would be interesting to see a synopsis chart.

Seems a bit pointless? Twin turbo set up, both the same size, for 180bhp?

As Nic says, one's in 1+4 the other is 2+3 in a parallel twin turbo setup (e.g. RB26DETT) not a sequential small + big setup for more power (e.g. 2JZ-GTE). It's going to give the least amount of turbo lag possible and they'll come in at very low revs but aren't going to give tonnes of horses.

[JudoKilli]

I agree. Two turbos producing less than one alone normally would? Seems a bit...well...rubbish to me.

He spends all that money and time on the car and still doesn't sort the bloody ears out!!

Yes, but for 180bhp? That was why it seemed a bit pointless. There are people on here making that sort of power from a decent NA 1800, a 2ZZ will make that as standard.

In general, twin turbo petrol engines are dying a bit of a death, in favour of single twin scroll turbos, MCS, BMW 335i for example.

Obviously, this isn't a new car, nor has it been made by someone with the resource that say, BMW, have, I'm just pointing out that all that hassle, and additional cost, over a single turbo, seems a bit pointless in this case.

In the case of the RB26, a lot of people looking for more power went to a single turbo set-up. My mate did on his drift R32. For something like an old S4/RS4, where you have one turbo per bank, it makes more sense, although Audi have moved on from that with their new mono-turbo set up, where the inlet is on the outside of the V, and the turbo sits in the middle, with the exhaust from both banks feeding it.

[onion86]

Yeah I agree it's a bit of a waste of money and I'd much rather have 1 big turbo with more bhp, but makes it a bit special to him I guess may have been his random little project. It's still going to be a completely different drive to the 2zz with it's top end and doubt it would've been masses of additional cost over getting 180bhp from a N/A as that's quite expensive!

[Wabbitkilla]

I think it's very likely the quoted hp is rwhp which is the usual standard for measurement in most articles I've read from Americans.
Which is actually healthy when you consider the losses in the drivetrain.

It is an expensive route  but I'd hazard a guess that the boost is almost supercharger like and the torque should be impressive .. which is why I say it would be good to see a dyno chart. It's an interesting setup, quite unusual really and would have advantages over a twin scroll turbo while have drawbacks in making sure boost is balanced well.

Is it worth all that money?
Well if you're "in" to something very unusual and original and have the money then yes, probably.
If you're just interested in a go-faster modified car and don't realise it takes more than just bolting a £50 gizmo on then no, probably not.
TBH it should be bought by someone who understands it and is interested in the specialness of it, it has a very specialist appeal.
And it IS the right colour   s:wink: :wink: s:wink:

[doogz]

Even if it's wheel horse power, there's a transmission loss of what, 15%, maybe?

A twin turbo 1800cc making 210bhp isn't that impressive tbh. I appreciate the fact that it's a twin turbo means it's possibly not about peak power figures, but still, not a huge amount of power. Although the ad makes no note of pistons/rods/extra gasket, so I'd assume it's running standard internals and standard compression ratio.

And as for driveability, that's very much open to personal opinion. To me, an MR2 isn't the sort of car that really needs a lot of mid range torque, it's a nimble RWD sports car, I don't think a turbo set up would suit it too well at all. And I do like turbocharged cars, I've had a few, but to me, turbos have a time and a place, and it's not in an MR2.

I doubt it's all that 'supercharger like', there'll be lag, and there'll be a boost threshhold, and the torque wll come in in more of a 'lump' than a linear fashion.

His car, his money, his choice. Was just posting my opinion that it seems like an odd (and expensive) way to get not too much power in that car.

[Wabbitkilla]

210bhp might not seem impressive, but it's the figure you get (around about) with a TTE turbo kit with approx 200ft/lb of torque.
You're probably seeing the same with this, you might not think it's going to improve the driveability of the car, maybe the owner feels differently .. many TTE owners feel the same way   s:wink: :wink: s:wink:  

We can't decide on the actual torque and power delivery, well because he hasn't posted a dyno chart with it... a bit of an oversight on his part as anyone considering this should really have an interest in it. The GT12 is a really small unit though and spool up with be pretty smart so it won't be like a supercharger but possibly quite close to the feel of an SC.

I agree driving a turbo car is quite different to driving a good na car, it's really subject which you feel is the best.
It's a complicated car with a clever setup which will have limited appeal to buyers ... that's a certainty.

The install looks quite neat and tidy too  s8) s8)

[nathanMR2]

Don't knock it until you've tried it, I say. I think with the right setup a turbo it can transform the 2 into the kind of power/grunt that should have been there in the first place for a sports car. Even the MGF got given more power than the 2  s:shock: :shock: s:shock:  ... but then they did fall apart pretty easy for sure  s:flame: :flame: s:flame:

I spent a reasonable sum of money modding my N/A to achieve a little extra power. I got reasonably good results at 163.0bhp and 135.6 lbft but bang for buck it doesn't really compare to the turbo set up I have now.

Ive had the opportunity to drive a number of different Roadster Turbo set ups and I have liked each one in different ways for different reasons.

I have one of the smaller turbos so it produces very little lag. It spools up at around 2.5k revs and gives you a nice little shove to get you where you want to be. Great for when you need to get out of the corners and makes overtaking far more enjoyable and comfortable. Gone are the days of having to plan the overtake for a few miles before hand, dropping the box and hoping that you're going to get enough power up to follow through the manoeuvre with a hitch.

I think this twin turbo could be an interesting ride. I don't see that these cars need massive amounts of power to be even better but the extra kick certainly made me fall in love with the car all over again. Im not sure what my current bhp is but I think its somewhere around the 200bhp mark. Its not the fastest 2 out there but it's the torque you feel from it and gives you the biggest grin. I expect this twin turbo could be pretty torquey so it could feel a lot quicker than its actual bhp figures.

[Anonymous]

It is very much going to be done for spool up time, where it might not make much power it also most likely don't have a big power jump in the power curve. I know I spent a fair bit of time looking at what turbo which is why I went for the skyline r35 turbo as it came in early of about 2k rpm but keeps power to the top. My old PE turbo started about 1500 rpm which was low enough that on cold tick over the car was revin enough to turn the turbo.

[doogz]

Maybe it's just me that likes my sports cars revvy and peaky, and not laggy.

Have to agree

Single turbo 220hbp
Double one 180!

Pity about the colour

[doogz]

You're kidding, right?!

That looks awesome!

[AmeR]

I think that's a generalisation that all turbos are going to have massive lag. The TTE certainly isn't one of those and I can only presume that this person has spent the time, money and effort to ensure that this is a similar drive.

Personally I think that a Turbo, if set up correctly, on these cars is just as much fun as a tuned up or stock NA.... Just in a different way. Without driving or owning all of them, I couldn't possibly pass judgement on whether a car would be super laggy or pants to drive.

It is nice to see something a bit different being done too.

No, I'm not suggesting all turbo charged cars are going to have massive lag. But there will be lag, unless he's fitted anti-lag. That's just physics.

And I do enjoy turbocharged cars. I have one. I just think different engine types and layouts suit different cars, and I don't think turbochargers really suit this type of car. unfortunately, it's something we'll see more and more of, as the industry swings back towards turbo petrol engines in general.

Anyone see the video of the road legal Formula Ford with the new 1.0T round the 'ring the other day? Mighty impressive time!

[AmeR]

Quick question though, have our owned a Turbo'd Rodster or at least had a good drive of one?

Nope.

[Wabbitkilla]

I've driven several different favours of Turbo roadster.

Even the ones with a bit of lag are fun and interesting to drive.
The ones i enjoyed most were the ones with the smaller turbos fitted, TTE and Power Enterprise just give the sensation that you have a bigger engine back there ... and I like it. I obviously don't like it enough to find the money to add a turbo to my own car ... but I do see that they add fun fun fun to the car. Like I said it's a different kind of drive to the na car. If I were to build a turbo onto mine it would be the smaller GT25r to keep spool up low down the rev range, apparently the Apexi kit achieves this very well. That's why I thing lag will be minimal on this setup and likely a rather entertaining drive. I'd still rather drive this than a fwd family car.

[Anonymous]

Turbo lag or as it is technically known of as exhaust gas delay is dependant on the distance the gases have to travel to get to the turbo, the temperature of the gases and the amount of gases required to turn the exhaust turbine. It is very possible to have a system that will have a turbo on our cars starting to spool at tick over. However the cost of quicker spooling turbo is that it runs out of puff much sooner than a turbo that spools later.

[loadswine]

Turbos can suit the Roadster very nicely indeed, if they are set up properly. You can achieve a variety of different characteristics of power delivery.
I've had 4 turbo'd Roadsters and they are all slightly different. They all worked extremely well with the car though, including my current one, which has a very linear power delivery, with no big spikes in the power curve. I do find the statement made earlier, a little surprising when there has been no experience of driving one.
Yes, there can be setups where the turbo kicks in and the power curve goes near vertical, but most I've seen on this car, don't do that.
The best for driveability so far for me was my V6, but that is a totally different animal.
The US car has pretty small turbos by the looks of things and I'd be very interested to see the power curve for it, even if it does look a little unnecessarily elaborate from first viewing.

That's turbo lag.

It is very possible to have a system that will have a turbo on our cars starting to spool at tick over. However the cost of quicker spooling turbo is that it runs out of puff much sooner than a turbo that spools later.

That's boost threshold. It's not the same thing. If you have a turbo set to spool and provide a decent amount of pressure at tickover, you'll still get lag when you change gear and hoof it again.
