TD42 Information

[mudski]

Kind of loosely looking around for a TD42 to chuck in my GU to replace the dirty 30. Nothing wrong with the current engine, low k's and goes great, but it ain't a TD42. I want something turbo and intercooled but have NFI on these engines. I'm thinking of buying something that needs a rebuild, chuck it on the stand and slowly build it.
Whats a silvertop and a blacktop?
Differences between the early GU TD42's to the last of them?
Can I use a TD42 from a GQ or should I get one from a U? Any advantage of using one from a later GU over the earlier GU's?
So many questions I don't even know I need to know...Lol.
Just so I know what I'm looking at when I see them advertised.

Cheers.

The later factory intercooled are the pick of the lot. Other than that a silver top with a turbo and gu pump would be the next go. Engine prices wil vary from 2k-6k.

With that conversion you need to relocate engine mounts on he chassis (cut and weld)

Lots of arguments to be had of which is better, silver top or black top.

Obvious difference is the colour of the rocker covers...lol

Silvertops were the original TD42 early GQ (Pre mid 90's) and have stronger conrods but the GU blacktops have the oil drain plug set up in the block which is a bonus. Loads of other differences between the two but both solid engines as you know.

They are the same block mate so should go in ok, I've never done this so hopefully someone else can advise more but I would assume the engine mounts would not line up from the GQ TD42.

Personally I would be trying to find a 4.2 from a GU TD42T and check out the forum for the conversions to convert ZD30 to TD42.


EDIT: Took too long thinking.....Matty answered before me...lol

You'll have to match or better the year you have ATM
EG you cant put pre pollution in, not that you would but,
if yours is 2001-2002 you'll need to match it. OR save and get a crate motor and build it
over time, As Newby suggests anything from 2001 is fine, later the better

Give Brett a call at 4x4Obsession in Melton he has done a heap of these conversions mate, he might even be able to line you up an engine. at least tell you the going rate in Vic for one and the legalities of the years and stuff. He has done this conversion many many times.

He might even have one in his shed you could look at give you a chance to look at the engine mount mods that Newby is talking about

[Alitis007]

Any engine conversions emissions need to comply with what ever is newer for eg if you car is '01 and you motor is '99 your current emissions should be fine but if your car is '01 and the motor is '06 you will need to get the emission system from a '06 vehicle. Not sure if you need to get an engineers cert but coz the car did come out from factory with the 4.2 you shouldn't have too many dramas.

Thanks for the info guys. I'm not buying straight away but am looking around. I don't want to find a good buy only to find out I found the wrong engine. So if they call if a black top, thats what I'm after...
I know of the emissions reg's, to a point, and the basics of what I will need for the conversion, most of it anyhow. Like I said, I just want to know what I'm looking at. My lil' 30 is still going strong so I'm in no rush. Plus, a few more weeks I think and I'll be ordering a locker.

Funny you mention this guy Darren. We informally met at my cousin's kid's first birthday party. Brett lives across the road from my cousin and was there at the party. I didn't realise who it was until he left and I asked the question of identity as I had seen him from somewhere.
But I will contact him I think when I'm ready to do the transplant.

It would be good to have a list of all the things needed to be done and bought for this work so when I am actually ready Ican make sure I have everything.

If you check out Simon Christie’s 4WD Pro Tips – Episode 24, on the website, Brett from Obsession 4x4 does an LS2 conversion on Danny's 80. Pricing was around $14-16k for a TD42T conversion. Add more dollars for a pump and turbo upgrade.

When doing my conversion I spoke to a local engineer and he stated that due to emissions I had to get an engine from a later model. Also in regards to mounts, if you were to cut the chassis to adjust the mounts to suit you will need an engineers cert (in NSW) for it, however if there is no major adjustments then your fine; just change the engine number, power and weight on the records because they came out factory with it. So making a bracket for the block was the path i went, which then takes you to I could put an earlier model engine in, however I think If you crash they may say otherwise.
