Have a 96 gq with a tb42e engine and am desperate for more power ! I have been wondering if anyone has turboed one and if so how to go about it ? How $ ? Boost levels ? Engine internals ? Lower compression level ???
Confused and frustrated any ideas or help would be appreciated : )
Welcome aboard... Drop in to our introductions section & post up an intro of yourself & a little on our Rig.
To throw a spanner in your thinking...lol... The answer is put a Ls1 in it & your power problem will be solved & it works out the cheaper way to go as well.
Welcome to the forum Nico.
How much more power do you want?
For a mild power increase a set of extractors with a 2.5" mandrel bent system will do and cost $1,200 approx.
For a major power increase these engines take nicely to being turboed. If you keep the boost low - about 7Psi and fit a big intercooler you should be right with the standard internals and compression. The turbo charger off a Falcon XR6 turbo is a good match for the TB42. You will probably need a programmable EFI computer. Budget around $6,000 for a complete turbo set up (turbo, 3" exhaust, intercooler, computer etc).
There is also the option Patch suggested of dropping in a V8. Keep an eye on Bigrig's members ride thread, we're getting ready to drop an LS1 in his GQ in a few months.

G'day mate - welcome aboard. Great people, information and laughs on here mate, so feel free to join in and make the most of it. Enjoy!!
Hi Tony yeh I have herd about the turbos of the xr6 go well with the tb42e do u know wot type or turbo it is and what sort of rev range I can expect the turbo to spool and reach boost ? Another thing is my engine has just ticked ova 300k would it be worth rebuilding the top end or will low boost levels be ok ????
Howdy and welcome Nico
Patch when you say cheaper do you mean the LS1 and install complete job cheaper than a turbo option?? IM SOOOO TEMPTED to get a v8

I've never done the turbo conversion myself so can't say for sure. The Garrett GT35/40 fitted to the XR6 boosts up from about 1500rpm (I've driven heaps of XR6 turbo's and a few F6 Typhoons) on a 4 litre motor. Fitted to a slightly bigger 4.2 litre but lower revving motor I would expect about the same. It's essential the inlet and exhaust are as free flowing as possible so the turbo can breathe and boost as early as possible. A gated boost controller will help as well even if it is still set to 7 Psi, it will stop wastegate creep.Quote:

Bloke in victoria does complete turbo setup, manifolds, injectors piggy back computer, everything you need in complete kit, about $8500 plus instal, sounds good but not cheap, will look him up and post details.
From a fresh rebuilt TB42e , full turbo conversionQuote:

Thats a 2nd hand , non rebuilt motor
AXT Turbo in Dandenong, gets good coverage in 4wd Action magazine, seems the goods.
Given the Dollars being spoken about above and an assumption that you might be ready to do this now i have posted a link to a Turbo Engine that is for sale on another forum
Sorry for the link off site, would normally avoid it but the OP may well be right on the money with this engine ready to drop in for $3.5k

If i was looking for a Petrol engine then this may be it! you'd prob get $1000 for yours once you take her out too ;)
It looks really really tidy and has got lots of other stuff bolted to it that comes with the sale too.
cheers and good luck
MR....I just tried your link & it only takes you to a log in page. If there is a way around this it would be great mate cos even if this memeber isn't interested another might be......Quote:

Glad it is going to a good home. That is a bargain for sure..
Yep and thanks old mate ... Patch is lobbing down on the weekend to check it out and off to Bigrig it goes!!! I didn't have a horn for a V8 as such, just wanted the power/torque and this engine is producing both of those in barrow loads!!Quote:

Did you bargain him down at all?
Great Buy!
Cheers mate any time

Top deal indeed mate - as you said, it comes with literally everything so no haggling done .. if it is what it is in the advert (which Paul spoke to him about and the guy appears straight up as can be), then it's a bargain as is, and he deserves the dollars he's asking for it ...Quote:
