Smoke, turbos and plenty of opinions!

[dogga1612]

G'day fellas.
So it turns out the TD42 GQ I recently purchased blows a bit of smoke. Not heaps, but enough to just see in my mirrors and enough to concern the old ladies driving behind me.
I did a valve adjustment and that didn't seem to do a whole hell of a lot. Ran some injector cleaner through her and achieved the same result, so I'm thinking it may be along the lines of the injector pump (will also check compression, etc.)

Next topic, I scored an rb25 turbo for cheaps off a mate of mine. I'm in the process of planning what I need to throw it all together.

And now to link it all together. Is it worth investigationing into this pump further or would people suggest going straight for a pump off a turbo GU?

Unleash any advice or ideas you have. Would be muchly appreciated.

Cheers

Is it turbo already? What colour is the smoke? If you can get a hold of a gu pump then it will be beneficial when turboing. Do you know the specs of the turbo? If your gonna do a pump it's best to do the injectors as well so the whole system is fresh.

[dogga1612]

Nah she is just an n/a at the moment. Only black smoke. Any ideas on what the rough going price is for one of those pumps? As far as injectors go, reckon get new ones or just put these through for a clean?

[dogga1612]

I'm also considering just re-kitting and upgrading my current pump. Anybody got any thoughts on the matter?

[Dales300exc]

Black smoke could just as easily be old tired injectors. They are a cheaper and easier place to start!

X2 with injectors, or the pump may have been wound up a touch..

Yeah I was going to go to hi flow in Springvale and get a set of reco injectors. Or do you reckon I just go new ones? Anyone dealt with hi flow before?

[Dales300exc]

Mtq are fantastic in dandenong. Use them for all our truck work. And ive used them for pajeros before. Reco exchange is normally the go

I am with dale300exc. The injectors and pump are probably gettinga little tired. How many km on the engine? Injector pumps can vary a fair bit, they can range from 800 anywhere up to 3k. Before going down the path of a modified injector pump what are you wanting to do with the vehicl? Like do you want a ball tearer of engine or somethin that is setup nicely that will pull a trailer all day every day with ease?

Injectors, reco ones should fine but if your concerned grab new ones. If you go through a reputable diesel fuel specialist then reco ones will do what you want, also if you want something in particular like pressures bumped up then you can ask them to do so. New ones will be a fair bit more expensive than reco as most reco injectors are based on an exchange service.

There is a small possibilty the fuel has been wound up, but on a NA td42 there are small gains to be had by doing this and most these days are turbo, which gets very good results.

If you can answer a few of the above questions the members on here including myself can give you plenty of advice on which way to go.

It's done a bit over 400k. It's going to be my daily, but I still want a bit of performance. Got any recommendations on places in the south east suburbs of Melbourne?

Also with dale on this one. MTQ do the DTS turbo systems for patrols. These are a very good kit to start with and with the addition of a Gu style pump with 11mm plunger and compensator you will get exactly what you want. Going this way though dont expect to see much change if any from 5k.

A turbo kit such as the DTS makes life a whole lot easier, everything is there with fitting instructions, the components are of a high quality and the results will speak for themselves. I am a firm believer in do it once do it right and have spent some coin because of this but it has been worth every cent. You wont be disappointed with the outcome.

Thanks for the advice mate. I can understand and appreciate the quality and simplicity of buying a kit, but when I can source it all myself for a whole hell of a lot cheaper, it's hard to say no. Plus, I'm an apprentice diesel (truck) mechanic, so
a) I love the challenge but
b) I'm also strapped for cash.
Oh and I'm 20, so naturally I want everything done yesterday. No time to save! :P

Ill probaby end up going to MQT but has anyone at all dealt with hiflow in Springvale?

[nissannewby]

Fair enoough. Do you know the specs of the turbo you want to use and its flange type? Also since your in the industry it will help with your injector and pump prices, I know that the prices I quoted earlier were a rough recommended retail price and doing what I do ;) I know I can get it for around half.

Not sure of the specs mate. They're impossible to find. It's a t28. Only going for a low boost set up to begin with. I've been told that on the td42 they're sweet down low but run out of puff a little in the top end, which is fine for what I'm after.

[dogga1612]

But I got the turbo, a dump pipe, oil lines and coolant lines for $150, so I'm pretty happy

[Alitis007]

T28 is tiny mate, on the RB26DETT they run 2 and thats on a 2.6ltr. If i you cant wait just buy the exhaust manifold from Ebay and a T04 untill you save up for quality stuff. Being an apprentice and 20 doesn't mean a thing, during my apprenticeship i did alot of modding and just like nissannewby i did it right the first time. You can get trade prices and source 2nd hand parts, why not source a turbo, injector pump and injectors from a GU4 Td42t?? That will be a good base to start from with parts that fit and work untill you put a bigger huffer on!!

T28 is a small turbo that on the RB motors is designed to spool up fast on engines that have a much small capacity cc wise.
I dont see this working and really think if you went ahead with this project would be money wasted and then you would have to spend more to do it over so in the end you will spend more than you should.
The same combined dollars will get you a far superior outcome with better quality parts than doing it twice on the cheap each time.

I dont just draw an opinion here out of the air.
I own a R32 GTR, also drive my Wife's Maverick just about daily admittedly Petrol but similar low down torque engine, I also drive Diesel trucks for a living and drawing upon my experience, know small fast spooling turbo isn't what you want for a sluggish much larger capacity diesel engine the two just don't go together.
I hear what you say about money we, well most of us have been there done that and trust us doing it twice is the expensive, longer, frustrating way
Just resell what you have and put your penny's towards the correct improvements.

Does anyone know what the Common term Specs are on the TD42 turbo charger? Looking at mine briefly i dont see it being much bigger at most than a small trim t03 ish....

[Dales300exc]

I love r32 gtrs! Good stuff!

[happygu]

If you are in the trade, just save up a little and talk to the boss. He will most probably let you buy new at his buy prices, if you have been putting in the hard yards at work and proving yourself to be an asset. Buying new at trade will most probably be cheaper than you can get most stuff second hand anyway.....

Sell off the gear that you have bought - you shouldnt lose at all, and you might even be able to sell the gear and make a couple of dollars towards the new stuff.

Don't take this as having a go mate, but it might be worth looking into it a bit further. Diesel motors of a higher capacity work well with turbos that suit smaller capacity petrol motors. Just look at the gt2860 or the td05. Both from small capacity motors, yet they are considered two of the best turbos for the td42. I've seen blokes running the same turbo as me and they say its great down low but just runs out of puff if you're revving it past 3500rpm. I barely ever rev mine past 3k, so I really see no issue. Only other problem is the ceramic turbine wheel, but that only ever arks up when you're running big boost.
But thanks guys. I do appreciate the the advice.

I'll be putting it all together in a few weeks hopefully, so I'll let you all know how I go and what kind of results I come up with.

[Lister]

On the subject of the ceramic exhaust wheel..I run an RB25det Neo at 17 lbs and have done for 3 years as a daily. Not only is it Ceramic but it has a Nylon compressor wheel as well. No reliability issues here. And i agree about the size and have been contemplating the swap myself as my boost is affective at 14-1500 rpm but would rather have the extra torque that the turbo provides at 1100 or lower.

[Robo]

Do what ever tickles your fancy it's your show.
I'm not offended, opinions is what was asked for.
My point exactly go past 3k rpm, so top end is ?.
Some time we need a top end. and when you need it !!.
I dont remember off hand but the 2 turbo's you quoted are up grades for larger kw on the small engines and these spool up later on the smaller engine,
Yes more suited to the larger capacity diesel engine as you quote.
I agree with you on that but were talking a smaller stock turbo, correct me if I'm wrong.

Its all good, good luck with it.

And what ever you do.
Stay away for ceramic exducer wheels, they can destroy a perfectly good engine.
If the wheel shatters there is a sudden drop in pressure and this causes a sudden turn around in exhaust flow and bits of that wheel can end up being sucked back in cylinder via open exh valve and destroy you engine quicker than blink.
And forget about it only happening on boost that's wound up, that's a wives tale.
It happened to me on stock boost, not under load, just puttin away from home at 30kph .
When it decides to let go you don't get any tell tail signs just a stuffed engine.
Alot of loud banging as the wheel is being smashed and embedded between the piston and head, compressing the piston against the top rings and tearing the boar to pieces .not lol.
