What is the benefit of hybrid turbos and what sort of extra power do they give over stock turbos. ( car also has decatted s/s exhaust).

 

Trying to decide if its worth paying the extra for hybrids over stock turbos.

 

Cheers.

IF YOU BUY YOUR TURBOS FROM SMITHY HYBRIDS WILL ACTUALLY WORK OUT CHEAPER THAN STOCK ONES. WITH UPRATED REAR OIL SEALS I BELIEVE.

I'm interested in getting Smithy's hybrid tubs - anyone out there bought some?

I'm interested in a set too - Smithy, Group buy????

Chuffin ell, if i go any lower i'd be on the floor :D I'm still using very old prices, gees... Check out a certain Nissan specialist in Essex, i'm hundreds cheaper than his cheapest Sold around 15 sets on this forum over the past 2 years, so if any of those guys are still members, sure they'll say how happy they were.

However..... being ever so helpful as i am, i will gladly approach my supplier Turbo Dynamics and ask for em cheaper still, if i knew how many we were talking about, would have to be at least 4 or 5 though i would imagine, i could definately offer my goodies greatly discounted for a number of members who bought turbos, say hardpipe or rad kits at half price ?

Always open to ideas, no women want in on a GB is there :D

smithy

Nice one Smithy :cool:

I'd be really interested to hear from people who've bought a set of these tubs; with regard to spool-up/power output - are they equivalent to JWT Sport 500 etc.

Martin........ive been lookin at this myself as mine have got to be rebuilt. As i understand it the hybrid turbos dont give you any extra power..... what your paying for is a more reliable turbo which can handle extra power from the other mods u make

 

smithy can probably give u the definative answer

Hybrids should see a nice power increase as well as reduced spool up times.

 

a hybrid turbo, as the name suggests is a hybrid mix of 2 turbos, usually a smaller turbine matched to a larger compressor.

 

the smaller turbine side allows faster spool up while the larger compressor allows high air flow.

 

different mixes of the 2 sides of the turbo will produce different characteristics & will vary the amount of power given.

 

deffo will be better than stock tho ;)

 

i want some!! just need to find a spare grand or so!!

I stand corrected........ i was refering to the hybrid conversion which can be carried out on your stock turbos by a repairer..... they state no power increase but more reliability

not strictly a hybrid then ;)

Paul's definition is pretty much spot on, cheers bud ;)

Also has to be said that even though you may think that your going to keep the car stock, when you go to sell and start plugging " Got new turbo's fitted mate" the customer would probaly be a lot happier knowing they are hybrids rather than new stocks as chances are he may want to to start on the road of modding, so in a sense a worth while future investment, whilst at the same time being stronger and quicker than what your used too.

Maybe blowing me own trumpet here, BUT as fitting costs vary from £600 to around £1,000 depending on where you go and what else you do, once you fit new turbo's, you wanna know that they ain't coming off again, i now know of 4 people who have purchased else where and after time from 6 months to 19 months, the turbo's are off again because of problems.

In 2 years of selling, i've had 1 turbo removed again, you may recall 300zx newbie (mark) had to have 1 removed after a very short time, i arranged for the turbo to be inspected completely and inspection report sent to me, a copy to mark and a copy to the relevant garage, it showed the damage was exactly as per the original stock one removed earlier which also identified what the cause was, the garage as you might expect were excepting no liability, so i had to sort it all out myself as i was the supplier.

End result was the garage replaced the turbo at a really low cash price, i got another new turbo couried over to the garage once they agreed to diagnose something first and paid a reduced cost at trade for the turbo, money wise it cost Mark nowt, me it cost nearly 400 quid to rectify, the garage got a few quid for the labour, so everyones happy, especially the customer, as it should be. Point being, yer paying top dollar for one of the biggest jobs on a Zed, you NEED that back up and as i'm here day in day out and use the same turbo's myself, i can provide that back up.

So far about 3 guys interested in a GB, if 2 more wish to take part i will see what price for deffo i can do, or Goodies i do that can be offered as well ;)

cheers

smithy, Go on, go on, go on, go on, go on, go on..... you know it makes sense :D

Smithy...... id love a set of yours ...but the garage is footing the bill.......... i cant persuade them that the upgrade is in their interest......... id be interested in the group buy price...... see if i can squeeze em a little........lol

Alfie,

 

Why not ask if you can pay the difference?

 

Vijay

Already splittin the cost of the turbos............their paying for the lump tp be pulled and the turbos to be fitted.........which i think is reasonable..........unfortunately they know that AR will do them for 125 quid a side so theyre unlikely to want to pay more than that.........especially as its coming out of the salesmans pocket.........tight fookers.....lol

Shame that Alfie, cos the labour can nearly be as big as the cost of decent turbo's and if they are paying that bit, yer half way there. Just hope it's not false economy for you, cos IF and of course it's a big "if" they should go again which can happen, yer lookin at quite a large lump of cash to lay out, good luck anyways.

smithy :cool:

Hi Smithy,

 

definitely interested - are they the stage 2 roller bearing jobbies - i was about to buy these myself from turbo dynamics - what do you do about the 14psi actuator - do you up-rate them? - let me know about any group buy and i'll be in - if you cant get enough people then no worries i am going to go ahead with this anyway. What do you do about the head gasket - i was thinking about 2 mm - rate the head and turbos to 2 bar an run approx 16psi.

 

let me know on here or email me on cjxxxx@ntlworld.com

 

Regards,

 

Alex

Hi Alex, i have the roller bearing jobbies on mine, awesome amounts of torque :D what sort of price did they quote yer ?

Why you replacing headgasket, having a rebuild or somethin ?

i had a rebuild at the same time but only cos the rings were knackered, so i had the block copper ringed.

Oh and i run 18psi on mine no probs.

smithy :cool:

HI Smithy,

 

stage II MD217 (ns) and MD218 (os) £995 each. quoted from progress engineering but no figure on fitting yet.

 

I was going to have a 2mm metal head gasket because i was led to believe that the standard one wont cope with more than 1 bar. The engine was rebuilt last dec by progress so they might be being a bit on the conservative side - i was thinking better to be safe than sorry. - New TB22's were fitted last dec as well but they've blown a gasket already.

 

at 18 psi what did you have the actuators set at? and what in the way of boost control and fueling control do you use?

 

how does your prop cope with 18 psi - you thought about a single piece?

 

oh - one last one - did you upgrade the downpipes on your exhaust - i am running hks but with standard downpipes - only solution i can find is custom made.

 

Regards,

 

Alex

Hi CJ, well if yer price includes vat for the blowers i can better it slightly, if not including vat i can better it greatly :D

Me block work cost just over 200 quid and it's a widely used form of sealing the head properly in motorsport, used with stock gaskets which are actually very good.

Dunno what yer mean about actuators, i'm using HKS Super AFR, APEXI AVC-R, Lumention air/fuel ratio meter and Apexi EGT sensor/gauge all to help get the correct fuelling, oh and an SE chip.

The Turbo short downpipe is custom made, cheap as chips, lol and then i have SE stainless down pipes onto me Blitz realize system.

Works well for me

;)

cheers

smithy

HI Smithy,

 

ahh - se stainless downpipes - i might get over there -

 

what was the head work you had done to seal the head - i'm a bit of a numpty when it comes to techincal stuff.

 

i think the standard td stage II turbos come with a 14psi actuator for those people not running boost controllers - with a boost controller wouldnt this limit the top pressure to 14psi - again being a bit of a numpty i might have got this completely arse about face.

 

The price i had was without VAT so put me down for a group buy. when do you think you will have enough people.

 

Regards,

 

Alex

1920 big ones delivered all in to yer front door ;) and that's now without a GB ;)

Yeah yer a bit arse about face with the actuator, don't worry you'll never run it on it's limit...

I think the tech term for what i had done was decking the block and copper ringing, got a piccie somewhere will dig it out and show yer.

If you want to order just complete the order form in my section and post awayyyyy.

If a GB starts it would be on the smaller cheaper hybrids see.

cheers

smithy :cool:

cheers smithy ~~~~> totters off to the smithy section to fill out form :D

Here's yer pic of me block after it had been copper ringed, look closely ;)

smithy

CJ go for actuators that run 8psi,you then ajust boost with a SBC having 1 bar actuators is not a good idea;)as when the new tubs bed in you could be running at 18+ psi all the time,and you can't get to them to ajust;)

hi mac - i heard steve had that problem - 80mph on the motorway and running 18psi - very scary.

 

boost control will be with a greddy e-01 hopefully SE or someone can set up the fuel mapping on the emanage system. With this does it matter what the actuators are set at ? The TD stage II come with 14psi actuators as standard although they say they will supply them with whatever anyone wants.

 

Regards,

 

Alex

Alex like I said bud,choose 8psi actuators,running 18psi is great fun however there is no way of turning it down if you fit the ones that come standard with those tubs.

 

Steve? I know Tony Lack has this problem with the new tubs he had fitted.14psi actuators that run at 18,as the new tubs bed in they will make 2-4 psi more;)
