Turbo for 4.5 Petrol Cruiser 100 Series

Wouldn't a super charger be more useful, power from the moment you put your foot down no lag, different brands eg sprintex, and I reckon a lot more reliable less to go wrong. Juat a thought. Have a great day Vitara

Unichip, extractors and 2.5" straight through pipe? Probably within budget and will still offer reliability / economy for touring.

Small block Chev petrol eg: GenIII 5.7 (not too sure I'd trust them though) or maybe an old school 400ci mouse motor with an aftermarket Holley injection setup? Will blow the old budget though.

LC V8100 series. The 4.7l 1UZ (?) bent eight is good for BIG horsies and a proven performer.

When I was looking at the CAPA kit for my 4500 Patrol, I think it was in the vicinity of $8,000 which I thought was a fair old whack.

As for cost, quite sure the supercharger at 7-8k was slightly cheaper than the safari turbo which was 8-9k from memory... though it would then do 0-100km/h in about 6 sec's !!!!

I think you'll struggle to get a turbo fitted for under 7-8k as you pay 3-4 for diesels to be turboed and with petrols you need extras like a unichip etc..

Russelvale turbo in Wollongong make a manifold for $750 and a gt turbo as in xr6 style for 2k, then you need a lot of plumbing and you have 240kw/540nm.
I bought a safari kit second hand off the trading post...suggest you look for one there too..
All the other mods will give you a small improvement, but this mod is balistic...

Matt, how good are your brakes now and how much are you going to spend on them? A 2.5 tonne vehicle that accelarates from 0-100 in 7 secs will generate serious momentum. You need to be able to stop too. Cant imagine I'd like to have a huge surge of power coming on boost whilst I'm trying to rock crawl. If you must have more power, look at supercharging. If you cant afford to do it properly, then dont do it. If you want a 4wd rocket, look at a Subaru XT and give up your rock hopping ambitions. Theres always some form of compromise. Me personally, I wouldnt bother.

Gday
A unichip would be the answer to the different boost levels..you can set 2 different boost levels, fuel and ignition graphs, which would give you plenty to be smiling about. It is hard to explain how a 4.5 responds to a turbo....if you feather the throttle, it drives sedately like a std one, if you get to 2500 rpm, it starts pulling real hard, and if you get to 5, and there is anything on the road out of the ordinary, it will break out. But the real benefit is at 80 kms/hr, and you want to overtake....which happens real quick, and all this at standard 6 psi boost.
I cant imagine how it would go at 10 psi or more, i do know of a drag car with 295 kw at the rear wheels (400 hp) running 18 psi
Economy is about 10% worse, power up 50%, and torque about thesame on standard boost.
My kit cost 2500 dollars, and after i recod it and installed it, about 4k. It was bolt on.
Lastly, my auto is a beaut rock crawler, the turbo has helped if anything, with such a large motor and no difference internally, it behaves itself till about 2k, but below that has more power and torque than a std one.

You wont find either a turbo or supercharger kit new for under $6K to fit the 1FZ-FE engine. IF our lucky you might pickup a used item for about $2500.

Yes it does make a difference, and economy only goes down if you DRIVE it. Expect better than 4.5km/L on LPG. Cant tell you about the petrol consumption because I hardly use petrol.

Alterntively youd be looking at a Chev LS1 or similar engine to get that type of drivability. Your start at about $6K for a basic crate motor, plus adaptors, plus, plus ....
