blowen turbo

[crazyclark31]

hey all
Just discovered that my turbo has packed a sad and crapped out . There is enough play in shaft that the compresser wheel has been spining agasnt the housing.

Its a ct26 off a 3gste celica.

Have been looking on trademe and have come across a Tdo5 with a 20g wheel(?). Would this be a good replacement as the ct26 was at full boost at aprox 1800rpm and stay there till bout 4000rpm
Would the tdo5 be close to that kinda operating range?
BTW its in a 88 gq shorty td42

best bet would either stick with what you have and find the same turbo or talk to a turbo shop pro

I agree... so much simpler to just get it fixed or buy one from a wrecker

[crazyclark31]

yeh was thinking the same thing but down here(invercargill) wreckers think they are gold plated going by there prices.
have been looking through some of the old posts an the tdo5 seems to be turbo of choice so am considering changing to one of these.
Am hoping that some of the guys that have had either or both of these could give me their opinion on what would be the better option. am only wanting to run bout 15psi

[benorange]

who you tryed down here. allan at all wheel drive spears is normly good on price if he has one

[crazyclark31]

no cant say i have. will give him a try.

thanks

I may be able to help..
I have a very good friend who builds performance turbos.
He might be able to save it!!

[crazyclark31]

hi big wil
Thanks for your help but think its a bit past being rebilt Ive stripped it down and everything has got damaged.The shaft has ground against the bearings and both the wheels have been rubbing against the housings. Pretty much everything that spins has grinding damage

When i stripped it down i discovered that the oil feed hole was partily blocked with gasket silicone. Teach me for being a lazy/cheap bugger! . So its been happening for a while.

Am still hoping for some advice on what is a good alternative to the ct26. Have been looking on tm and have seen a few choices but not sure on the sizings
Have looked at the following;
tdo5
tdo4
t3/t4
t28

Would any of these be suitable?
am running a standard pump to

Thanks in advance

Dont waste ur time with a td04. Also up for consideration is vf22 vf23. These are pretty close to a tdo5...

T3t4 are pretty dam cheap from nu. Usually come with a 12 month warrenty too. Abit laggy but not much worse than a td05 ( at least in the perforamcecar world)

[crazyclark31]

why not a tdo4? arnt they bout the same size as a ct26?

[stealth]

Without checking i would say ct26 is quite a bit bigger than a td04..well at least the intake side. The tdo4s just run out of puff. I realise diesal vehilces may use turbos a bit different to performace petrols as this is what im basing my knowledge on.

If you end up going subaru flange (over mitzi) you have lots of very cheep options for upgrades as well.

[rangimotors]

td05 would be good, I would of thought the ct26 was a bit small to start with for your engine..

[Big Will]

In my personal opinion, the TD05 is one of the most versatile turbos around.
They are very strong, they make loads of power and on your 4.2 it should be perfect!
I have been looking at also using one on my 5L-t but i have decided to go quite a bit bigger as I'm not to worried about bottom end torque.

Another option is a DSR430.
This is the route im heading.

But that is for whole kit, just grab a internal waste-gated turbo and adapt it to your manifold..

Just another option..

If you want any other option gimmie a PM and I will see what my friend has in stock in the 2nd hand stores..

[crazyclark31]

exellent help guys much appreciated.
FYI am going to go the tdo5 route.
Just one last question am i better to go down the mitsi or the suby flange mount? Not concerned bout upgrades or odd size/shape mounting. Am more concerned about reliability. Will be running with a top mount cooler with a fan underneath.

again thanks all
Mike

[Big Will]

As far as reliability goes, the turbos internally are the same.
With the Misti there are 2 different option for exhaust housing size from memory a 7cm and a 8cm, which will dictate at which RPM the turbo starts to spool up.

[crazyclark31]

yeh had a feeling that was the case but better to ask silly question than suffer a silly mistake .
Have heard that was the case. as its a daily and i like the pull from low down its the(mitsi) tdo5 with the small 16g wheel im after aye?
Are the suby tdo5s' all the same size? soz bout all the questions but wanna get it right
ta

[Swamped]

I think theres a twin scroll version and even a reverse rotation tdo5 for the mitsi's. the HR maybe??
Would mean the compressor housing would be positioned more favourably. Id probably go subby assuming the wheel sizes were right as they are easy to find but mitsi could be just as good.

[crazyclark31]

dunno about the twin scroll but yeh from the evo4 onwards they spun the motor/gearbox around so as far as fitting to td42s they are a far easier and more favorable fit. will prob go for the subby version as as you say they easy to find.
FYI when they spun the motor around they upped the kws to 205max

[Swamped]

I meant the turbo rotates in a reverse direction so the compressor output is nicer to fit. Maybe thats what you meant all good.

[crazyclark31]

yep that what i ment. basically everything is a mirror image(incl turbo) of the earlier models.

[stealth]

Early suby td05h 16g had a 90 deg on the intake. So u either want 2 mod the intake side (prolly not worth the hassle - but any alloy welder will do it) Or find a straight intake version at a guess after 1995, if you go suby replacemt turbos are common and cheap. It will be facing the right way from factory but due to the nature of a customish manifold either mitsi or suby will work the same.

TD05 with a 16g comp wheel is a good unit for a daily driver TD42. 18g and 20g compressors are normal upgrades from the 16g if you're looking for a bit more performance, but only really useful if you've done a fuel pump upgrade and intercooler etc.

I ran a CT26, with 6 bolt exhaust housing (twin-wastegated and twin entry) on mine which was progressively upgraded with T04-B and then T04-E wheels (52 trim)......with a bigger fuel pump and no intercooling it went very well, but if I were to do it again I'd just go straight to a 20g.

Search the Nissan threads, as I've posted the BHP ratings of each of the TD05 upgrades numerous times.

[evyauto]

Im running a VF10 early rex one on mine and it makes a huge difference down low but runs out of puff at 3grand considering it pulled 4 before turbo conversion. am going to upgrade to the VF22 later rex one as one of the boys here has a damn near identical set up to mine with the 22 and it goes just as good down low but pulls hard all the way to 4g.

[evyauto]

and mike when are ya gunna learn sillicon not your friend on oil lines and things????

[crazyclark31]

yeh man. You know me
all sorted now. Farking truck hauls and on only running 10psi. 95 Wrx tdo5h with comp housing modified to a strait intake.
Have heard the the bbearing turbos don't last on diesils.Someone correct me if im wrong
And gota run restrictor on oil line on bb turbos but bet you know that aye bout a .8 to 1mm hole i think

[tweake]

afaik they are fine. what generally kills them is dirty oil. either fuel contamination or way to much soot in the oil.
also i would guess there would be a few dumb buggers that leave the water lines disconnected (as you can do with non-BB turbo's). as there is little oil going the through the BB to cool it, the oil soon cooks and damages the bearings.
