Thread: Turbo Upgrade

<div class='quotetop'>QUOTE</div><div class='quotemain'>I have heard that this turbo upgrade is a water cooled turbo and that it puts more pressure on the cooling system[/b][/quote]

not really, as the stock Garrett turbo is technically oil cooled, and that heat ends up in the cooling system via the oil cooler in the right hand coolant tank of the radiator......

<div class='quotetop'>QUOTE</div><div class='quotemain'>also pull the engine breather hose off cut it shorter ( just before the turbo ) and refit into the turbo pipe[/b][/quote]

what are you calling the turbo pipe ? I'm curious where you've gone with the breather.
Race engines often used to feed the engine breather into the exhaust system, usually at or near the collector, utilising a venturi effect to evacuate the crankcase. These days multiple scavenge stages are used on the dry sump sytem for a far more effective result.

I've replaced the tube from the wing to the air cleaner on my Defender with 3" hose, and hacked the restrictive 2.125" ID spigott off the snorkel air box for the slightly better 3" OD section 1.5" further back, and noticed not a scrap of difference over my secret test track. I also went back to a paper air cleaner from a K&N after 20,000km a few years ago, after being very suss of the K&N's ultimate filtering abilities, since borne out in an independent test overseas. I didn't notice any drop in performance going back to a paper element.

Another kit option is I sell a kit with the 2.8 TGC turbo
(well it's not really a kit just a list of spare parts I bring in with the engines & put togther in a box, so you can order whole kit or some parts) includes
the TGV turbo (obviously)
exhaust manifold
exhaust manifold gasket
turbo gaskets
set of exhasut manifold nuts & studs (old ones are often siezed & break on removal)

yes oil lines are suposed to interchange (I have never fitted one myself but asked I guy who did) he said was as simple half day job

Exhaust off the turbo is differant (new turbo is on differant angle) so you need a local exhasut shop to make up a new "dump pipe" off turbo (will cost appox $100 fitted) some people have run std disco exhausts (even with 2.8 engine) others get full 3" free flowing system, std is fine but bigger is better (note 3" with free flow muffler is not load on this engine)
for same reason (turbo angle) you will need to rework air inlet & outlet plumbing (cut & shut)

$ total for "kit" $2300 inc GST (I'll inc the freight) yes can do something for cash sale

this should give you lots of extra power esp low down in the RPMs
the TGV turbo is variable nozzle and gives full boost from approx 1400RPM

you don't have to re-adjust pump again but it will increase performance more if you do (I take it you know this is fairly straight fwd job and anyone can adjust pump)
