TD04 turbo

[Kryton]

im guessing if your friend was to sort some more of these out then he could earn some $. i for one am very interested in performance of these and of course the price

have been thinking of a td04 conversion myself but im a bit worried about the amount of work and cost needed.

My thoughts exactly. I am also very interested

[LouisC]

no need to change either of them. just purchase a wideband 02 sensor and module and a gauge.. innovate make a LC-1 kit with gauge and sensor. this is only to keep a eye on fuel mixtures.. if it starts to run lean then look into upping the presure in the fuel lines.. if it still lean then it will need slightly bigger injectors. then you will need a re-flashed ecu or a Apexi S-AFC.

o.i.c. Thanks. Actually I changed Mines ECU already. Do I need to install emanager to remap the fuel volume?

OK, no problem and I can ask him but I need to know:

1)how many bros here are want to have a pair of this bloody , discount may be bargained
2)the turbine is totally new but a pair of used TD03 casing is need for this modification and rebuilt, any idea? source 2nd hand in HK or post from UK?
3)as I am in HK, does any bros in UK side be responsible to receive the turbos?
4)the turbo need to do balancing in Taiwan after rebuilt and modification, I need to check the time frame and transportation cost...
5)of-course, I need to check my friend's free time to do this..

[Nutter_John]

well I'm sure we could do a special remap on one of our PFL ecu's to suit these on stock injectors , I recon you would get a good amount of extra power but may struggle to reach the compresor's max due to a small turbine from the rd03

I am happy to send you a pair of stock housings. How much money are we looking at roughly?

[LouisC]

This should be the fastest vr4 in HK modified by JUN. Two TD05 turbo installed. 520PS (on wheel) and 641.5Nm @5690RPM with 1.5 kg/cm2

I've seen that JUN one before

funny how the big single td08 is so weak

TD08 is the 2nd stage modification and the owner didn't like it. Then he sent a whole care to Japan for modification.

Louis, if any possible group order on td03/04 hybride, then I'm in

Hi LouisC,

1)how many bros here are want to have a pair of this bloody , discount may be bargained

You may find quite a few of us here in the UK are interested, you should put up a group buy offer when you have a packaged deal.

2)the turbine is totally new but a pair of used TD03 casing is need for this modification and rebuilt, any idea? source 2nd hand in HK or post from UK?
3)as I am in HK, does any bros in UK side be responsible to receive the turbos?
4)the turbo need to do balancing in Taiwan after rebuilt and modification, I need to check the time frame and transportation cost...

I have a better suggestion! Find someone in the UK willing to take delivery of a lot of new TD04 wheels, modify and balance the new turbos here in the UK (saving money and time) and then sell them on an exchange basis (like Nutter_John / KinkyAfro do with their 7201 ECU reflash mod)

I for one will be interested in this, I'm going to be aiming for 320+ horses on my VR-4 and I understand that rapidly approaches the limit of the TD03 turbos.

[foxdie]

Also, just to start the ball rolling, I've just emailed a Turbo Balancing company in the UK for a quote on balancing batches of TD03s with TD04 wheels in them

[Wobble]

nice one jason,

cant wait for the out come of this post,i will snap these up in aheart beat.
.
anything can do to help to get this up and running and i will.

[Kryton]

Can't wait to hear how much these work out to. Nice work Jason

I suggested (over a year ago) that somebody contact CRTurbos regarding hybridisation, in my thread about the recons I bought http://www.clubvr4.com/forum/showthr...-get-them-here!
Perhaps now that we have some confirmation from abroad that something a bit different is possible it could be a good time to contact this company for information (which hybrids, recons etc turbos for a lot of the big and experienced UK tuning companies such as RSP: Rising Sun Performance, Conceptua Tuning, even Ben from Eurospec told me that he has had dealings with them).
I would enquire myself but I've lost a bit of interest in power chasing with the Legnum as I've got too much potential and work now with the Skyline and this is something that I wouldn't really be interested in at the moment unless it was chirpy chirpy cheap cheap!

I understand what you're saying, Jason, about somebody here, effectively, setting up their own cottage industry modifying TD03s, getting them balanced by someone else and then offering them for exchange. This would be the cheaper option as it would be an enthusiast doing it for the love of the car as well as to earn some cash. How realistic is this though? Do we have any peeps that could modify the housings, change the innards etc and that would be willing to do it? Balancing a turbo is not too much of a problem as there are companies that will happily do it for £40-50 per turbo.
It would be great if it comes off!

Have some updates now:
1) The price for one turbo is not as cheap as I expected (around £490 per turbo,including new TD04 turbine, balancing and modification of housing). The housing modification (both fresh and exhaust air sides) is not simply enlarging the outlet, but also the housing inner side to accommodate the bigger TD04 turbine into TD03 housing.
2) If more than 5 pairs of turbo to be confirmed, I may able to request for extra discount (may be 5~10%).
3) For the turbo housing, you may group all 2nd hand housings together and ship to HK or I source some 2nd turbo in HK (around £80~£90 per pair).
4) The above cost not includes the transportation between UK and HK.

Finally, I have another suggestion. You may order a pair of turbo and ship to UK. Then, source any other turbo manufacturer in UK to do such modification and the $ could be further reduced...

Hmm, at that price I'm not sure if it's worth it, can anyone else comment?

[Nutter_John]

£1000 for a pair of hybrid turbo that means you can use the stock manifold and downpipes is a good price to be fair given it should get you on the door or 400 bhp , you pay £1300+ just for one hybrid turbo on an evo

My concern about this whole thing is the amount of metal needed to be removed from the housings and the long term stresses on it , thses have been looked at in the uk by Two company's and they both said it's not possible to do anything with the td03's due to the size increase needed . Has an xray's been taken of the housings after they have been used for say three months to check for internal cracks and stress marks in the metal ?

That's £1000 before shipping / import tax / duty / VAT / penny pinching bas***ds getting their grubby hands on it

That's a good point, what are our alternatives at this point that can keep the same pipework (or maybe just a small aka cheap change to implement)?

[LouisC]

Hmm, I also concern the price many be little bit high and I am still considerating......Also, give more information about the performance.

1) EVC setting Low- 0.75bar with peak pressure 1.2bar and High - 1.2 bar with peak pressure 1.6 bar
2) He has droven his legnum for 3 months at daily basis (around 100km per day) and so far, nothing problem observed.
3) Nothing modification works on the manifold, just simply bolt-on, but a pair of water pipes to turbo need to cut-off as the TD04 turbo without a need to cool down by water, just by engine oil.
4) As no any more water need to cool down the turbo, the water temp drop around 5~10C but the oil temp increase around 3~5C

Regarding the modification works for housing, only the fresh air (alum. housing) need to be enlarged and the housing thickness will be reduced but it should be not a concern as the temp and pressure at that side is not too high.

For the exhaust air, the enlargement works involved are cutting off the existing inlet ring and welding another bigger inlet ring to accomodate the TD04 turbine. So, the housing thickness at exhaust side will not be reduced. -see pics TD04 (left) vs TD03 (right)
