Have a 2.8L Hilux fitted with a safari snorkle, k&n filter, safari turbo running 10 psi boost and 2 1/2 in exhaust running no muffler.
This does not make a whistle sound at all, like some turbo diesels do.
What set up do you have and does it whistle?

super mega happy special setup

ie it comes free with the toyota ct20 turbo when you bolt it on

LMAO i would check to if you have a turbo on [/code]

Isn't the whistle caused from teeth missing from the spline? ?

Mine whistles, though it is hard to hear over the exhaust at the moment, I have a 300ZX turbo on a 1hz- 80 series, boost set at 10 PSI.

I run ct20 turbo, snorkel and 2 1/2 exhaust and mine whistles even at idle. As long as its making boost seems strange to have no whistle are you running a boost controller or anything?

no boost controler just the std Safari set up.
speco in dash boost guage reads 10psi on boost and spikes up to 11 psi

mine starts to whistle about 1700 rpm, thats with standard hilux exhaust. But mates have got theirs turboed and u have to really listen for it to hear it. It could depend on the make of turbo too. Mine is a DTS. Have u got a flexi joint in your exhaust?

mine sounded its best when it was a piece of pipe about a foot long just hanging off the turbo dumping down near the front tire

Muddylux, I have a ct20 on my hilux and it wouldn't whistle much so I took the muffler off and replaced it with a hotdog and then dumped it out just behind the cab. Its only 2" pipe but everyone looks as I come up the street now. Got heaps of whistle and the exhaust is still not very loud.

A lot of you guys mention the ct20 turbo set up is that the 2LT system or an aftermarket deal


Cheers John

im pretty sure toyota 2.4 turbos are ct20s (please correct me if im wrong) as i know that denco sell the CT26 for the 75 and 60 cruisers because they are what ive seen.

yep thats the one a ct20 setup off a 2.4td from japan can be had complete for about $800 here, bolts straight on.

you can goto repco and buy a turbo whistler for $2.99

lol whats this turbo whistler? I have the same deal, cant really hear the turbo spooling on mine, but then again the turbo is on the passenger side and have never had the chance to hear it n e where bar the drivers seat.
Compared to mums 1hdt it whine like a dog on heat!

i was told that the 2.4 turbo setup is crap on a 2.8 cos its too small is this true?? or is it a case of just winding up the boost and fuel to suit??


Cheers John

I have a schwitzer turbo on mine and it whistles but not very loudly. Usually when they whistle loudly they are about to go bye bye. Especially the CT20 turbo`s. So be glad it aint loud i know it might sound cool but it usually meens somethins a miss.

You want to hear it put a blow off valve on.

Yeah i got a DTS on mine and I cant hear it whistling much inside although people outside reckin they can. I looked in the CT20 and even bought one but couldn't bring myself to fit it up with the feedback being 50/50 for and against..

i will have a 2LT (with the CT20) available soon if anyone is interested...

any one else got an opinion on fitting a ct20 to a 2.8???

I hate the turbo whistle personally. Once had a job in Dirranbandi driving a 400 odd Hp steiger tractor and i could literally see the big huffer through the glass. After 12 hours at full noise, you cant sleep cause i would lay in bed and hear a whistleiing in my ears. i swear i have industrial deafness cause of it.

Any way, its your pusslux and im sure it hasnt got the same amount of Hp.

i brought the 3L (2.8) with the ct 20 turbo already on it.....It runs great with bout 12psi in it...but unless you really know wat u r doin with fuel i reckon get it done professionally.....i thought mine was great till i took it in to them...made it richer - gos faster - runs cooler....
