Hybrids?
As I mentioned in my last post I am now considering upgrading to Hybrids while my Turbos are being replaced/refurbed.
My question is: Is it necessary? My aim is to go BPU once my engine is sorted, which is now almost done. My target BHP is 350-400BHP (at the flywheel) and I am not interested in going single. The car is a daily driver, and I want to leave the plumbing as close as possible to what Toyota intended, but release more power through freeing up the engine's in-built restrictions and allowing it to boost to circa 1.0-1.1 Bar. 1- If I am retaining the sequential setup can I achieve that kind of output without going Hybrid? 2- What are the pros and cons of going hybrid? 3- Will I be able to install Hybrids with everything else still stock and then go BPU later, or will the differing internals of the Hybrids affect the stock sequential operation? 4- Does anyone have any experience of Hybrid reliability over Stock? I have been searching this subject and realise it's a bit of a 'Marmite' question, but I'd appreciate any opinions. |

1. Yes. Standard j-spec turbos will give that sort of power. 410bhp is the absolute max on them though.
2. Pros .... Everything stays standard, you retain the sequential setup, insurance doesn't care. Cons .... For the same money you could go some way towards going single. 3. Yes. Sequential system unaffected. 4. Not sure. Be interested to know myself. I've heard good and bad. Probably depends on the quality of the hybrids. If and when my standard turbos need replacing I shall be putting in hybrids. The cost of going single is just too high. And I'm sure once you do it that you need to regularly tinker with the setup to keep it running right. (i.e. rolling roads, plugs, fluids, etc) Plus I like the sequential setup. (Saying that I do quite like the idea of going single with that huge chunk of power and torque) To my mind going hybrids is a one-off cost of between £1000 and £1500 fitted and going single I don't believe would see much change out of £6000-£7000. (If I went single I'd go for the PHR Street Kit though, 650 injectors + either eManage or MAP-ECU2)

However 1 - Yes, you could obtain around that figure with stock turbos. 2 - As per Flynn's post. If you go for the highest stage hybrids there can be a slight delay in boost but I suspect you will be hard pressed to notice it. The biggest Pros is as Flynn says, retain stock setup and no need to declare to insurance. 3 - Remains the same. 4 - I know of some people who have run Hybrids for years and others that have run them for only a month or so and they have gone pop. It comes down to a number of things, but most importantly how good the suppliers workmanship is. If you go down this route see if you can get at least a 1yr or 10,000 mile warranty on them. IMO i believe that for what you are looking for that Hybrids maybe a very good solution.

Do not refurb your old turbos and buy hybrids do one or the other. The expense is just not justifiable

Thanks for all the comments guys - they've been very useful and a great help.
I think I'll probably get them done if at all possible now. Considering its CW working on the car I'm confident he can advise as to who's workmanship is the best. I'll need to do some reading up online if I can access the relevent sites out here. We'll see. My only concern is being at the end of a long communication chain just now, which might slow things down. The next few days will decide things. Thanks Again. |

It's a technical thing mate. You wouldn't understand.
(Either that or I pulled the figure out of thin air.) (Or it's the figure I think I'd be happy pushing the j-spec turbos to without worrying too much about them going pop)

When I spoke to the insurance company about hybrids, they wanted an extra £500 odd as they claim a proven 120 bhp after having them fitted
Do you have to inform them??

You should inform them .... but ..... it's a difficult thing to spot looking at an engine bay. You'd really have to know what you're looking for to work out that they were even hybrids. It's just different internals.
You went in a single turbo car didn't you Kev? How was that?

If your going hybrid your good for 1.4-1.5bar
But your 440 injectors would only been good for around 1.1-1.2 bar so you would need to change to UK 550's and a resistor pack too see good fueling at 1.5 bar |
