TB42 Turbo manifold

[hokey]

Hey,
Thinking about turboing my maverick petrol 4.2 and was wondering what options i have in the way of manifolds. been told diesel ones work. anything else?

what should i pay for a diesel one or any other manifold for that matter.

Thanks, Calvin

This one uses the original petrol manifold ith a home made riser extension....

Thanks for the links. heaps of reading there.

Just wondering what the J pipe manifolds are like and also the log manifolds as they are both something that i could have a go at fabricating myself. or is it not worth and i should get a proper tube mani made?

Cheers

Deisel ones are $350 from MTQ.

[hokey]

Thanks for that Dan.

Think the J pipe looks to be the go but just wondering about strength. Do people run bracing to the turbo at all? and is just normal exhaust tube used?

just build your own or get a rice burner shop to build you one, a spagetti style steam pipe one. I will be starting to make these up soon to sell off but at the moment have to get the new shock setup done in my car before christmas

Thanks for that, can I attend there in a double bubble or covert plain wrapper. Don't want to scare the customers away.

Yes, unmarked would be nice!!
He can at least help steer you in the right direction.

Does the MTQ one have a T3 flange ?

RN just pop the bonnet and pretend that your getting some go fast bits added.

Petrol heads used to ask us about the interceptors, whether they had been chipped, etc..after a while we'd tell em anything they wanted to know, chipped, high flow air filter, HC pistons, cop cam, cop shocks...

No wonder they are popular on the SHM...christ they are well serviced but ???

[dansedgli]

Yep.

I got one from Ezrail on here for $300 + postage. Its new and also has a T3 flange. Im not sure if he has more of them though.

Get a custom stainless steel tunned length manifold from CVEPefromance as said above such a difference over cast crap IMHO.

Car made 300rwhp on 33's and beats turbo'd skylines so it speaks for it'self. And 31's tyres are completey dangerous

Have you tried both for comparison? How was the tuned length one better?

How wouldn't it be? How could a tunned length one be sh1ter then a cast one ?

It's like saying my standard exhaust is just as good as a 3" mandrel

[hokey]

how much did the manifold cost you? also what did you pay for your turbo?
Thanks

[ELF_83]

when you make all the runners the same length as in a tuned length manifold it causes the turbo to come on in more of a sudden rush and can make them very hard to drive in sticky situations in the bush, if you stagger the lengths of them in makes the turbo come on more progressive which i have found is alot easier to drive off road. if your not chasin outright HP that is the way to go.

And in some cases wouldnt 3 inch be overkill?

Without trying both how do you determine that the cast manifold is any sh1tter than the tuned length one?

I bet for your application you would feel no difference between either if you managed to mount the wastegate somewhere where it would be as effective. Off the rear housing for example.

My point is more that you shouldnt rule out a cast manifold just because you heard on the internet that the tuned length type is so much better and from the way it looks.

I know a guy running a plain log manifold running 9 second quarters in an EA. There are plenty of other falcons running around with tuned length manifolds and none of them are even close to catching him. Does that make it better?

Imo a cast manifold would be more reliable in a 4wd which is likely to do water crossings and go through mud quite often. Stainless manifolds are known to crack in cars where the engine bays never even get wet.

Horses for course I guess. IMO the extra $700 isnt worth the poofteenth of an advantage you gain.

Might wanna Email CVE Peformance to get a price as they may have changed since i got mine.

[dansedgli]

CVE quoted me $1050 for a tuned manifold.

$750 for a log manifold and $650 for a cast one.

That was 2 weeks ago to suit my 4.2.

[hokey]

Crikey! i don't think the money is worth the performance gain
J pipe is alot cheaper and if that doesn't work out then maybe i'll just build a log manifold myself out of RHS....

I went to a few turbo shops and most recomended just a log manifold for my TB42.

The only reason i got an extractor style manifold was i got it mde by sandy Bowman and it was the same price as what i was quoted for a log. PLus i didnt have to bring him my patrol.

There are a lot of very quick cars getting around with log manifolds. I was asking the same question a few months ago and it just came down to price. The only reason i didnt gt the diesel manidold was that the one i was looking at placed the turbo too close to the firewall but i'm sure there are others that dont. My manifod was $800 but if i could have got a cast or log for cheaper that placed the turbo where i wanted it then i would have gone that way.

Each to their own but you cant say log manifolds are sh1t just because u dnt use one.

Im not disrespecting the usefull information given. BUT

No one has seemed to answer the question asked......

Does a Turbo setup from a 4.2 TD work on a TB42 ?

If it does bolt on and work, is it worthwhile ?

[nzdarin]

Tuned length give most of the advantage in the top end and a TB42 doesn't really have a top end (rev range so to speak). While a tuned length will always work better than a log, the difference isn't probably worth it on a 4x4. If getting a tube manifold I'd get it made from heavy wall steam pipe and bend rather than SS due to cracking associated with SS. SS is fine for on road but life would be a issue in a 4x4.
My manifolds are a log style either side made from steam pipe bends and heavy wall steam pipe for the cross over etc. They ae heavy but they will last. Once everything is sorted I'll get them HPC coatd and no rust worries either.

[MrMaxi]

Anyone priced up a J pipe ? anyone actually using one ? Iknow they use these on FWD cars.

YES

the exhaust manifold, turbo and exhaust all fits

you will just have to fabricate the pressure pipe.

you will probably need a new oil line aswell and you will need to put in a drain in your sump.

the td42 turbo ( the actual compressor itself) would not be particularly suitable for the petrol engine either.

Don't think it'd be that expensive as it's just as the name sugests, a pipe that comes of the outlet of your standard exhaust manifold and is in the shape of a J with a turbo flang welded to the top and the turbo sits there. look in the links in RN's first reply and someone there is using one

Yes, Hokey in New Zealand has one on his diesel...I like the idea of that as I am not after high end grunt just low end so It can't be that restrictive. Keeps the turbo away from the firewall too and less to remove. Some members have broken exhaust manifold studs getting the nuts off to remove the manifold.

Just means getting a dump pipe fabricated from the turbo to hook up to the exhaust. I will go standard exhaust as the original is still doing the job.
