Hilux 3l Motor- Oh so slow

[Tuflux308]

get a surf turbo (ct 20) i got one from trading post for 500 bucks with all the plumbing, bolts straight on just had some exhaust things to do otherwise was as simple as boltijng it on.. being a 2.4 litre turbo, when put on the bigger motor, it really make it puch straight into boost at low revs, used to thrash dts turbo, safari, and all the rest, in bush would cruise on 1500 revs then as soon as you hit the gas would pull straight off. tried an upgrade and spent 3500 on safari turbo an intercooler, and all i got was a slower much less tourquey truck, seriosly ring wreckers, get on to a ct 20. cheap and amasingly good performance gain.. when turning 36 simex's will beat 5l turbo diesel with stock tyres. had enough go i broke 3 gearboxs.

easiest and also cheapest is the CT20 from a surf. Easy to bolt up. Will run 10psi easily, a water cooled turbo is a little bit fiddlier to hook up. There is also a few other turbo`s around ie; switchzer also not a bad turbo and should be around the same price.

Expect to pay like 2k if you ask a mechanic to source and fit a turbo system for you.

All you need is to get the parts of a surf, watch ebay and the trading post, should get the lot for around $400 then install yourself, or expect around $500-$1000 for a mechanic to hook it up

The CT20 is water and oil cooled just don't have to do the water if you don't want to and don't care about it lasting.

Since when was the CT20 water cooled?

[sniper]

I thought the CT26 was water cooled, never heard of a water cooled CT20. CT20 is also smaller so it spools up at lower RPM, better for take off power. pls correct me if im wrong

I wouldnt bother about a water cooled turbo really as an oil cooled will still last a long time. If you want it to last longer then 300,00kms then go water cooled.

[Turbo Tonka]

is a small turbo good then?????my old 2LT used to spool up quickly and it was a pain in the ass on down hills and banks off road,the truck would take off compared to my mates 2.4 or my now 2.8 lux.It was great onroad though. Was this the reason, i never looked into it??? sorry to interrupt again

[whiteknight]

Check these guys out they have brand new turbo kits for around $2000 for the 2.8 from memory

got ct20 on mine and spools up bout 2000rpm, which i think performs better offroad ie. its gets more power quicker and easier when you need it. I think it really comes down do the drivers and their style

I have water lines running into my turbo and its a CT20

My 2LT is using a CT20 and there are no water lines going to it!

[sniper]

Are you sure its a CT20 and not as CT26?

Not saying that its not possible for a CT20 to be water cooled i just have never seen one before or heard of one and i have seen alot of surfs and hiluxs.

[whiteknight]

I have had 2 CT20's and both where water cooled.. although i never ended fitting them up I went for a Turbo suited to the 2.8D instead.

[LuxyBoy]

The water lines connector maybe blocked with a plate on those that don't have them installed. Trust me they do run water; just not everyone does it. If anyone wants a pic of the water lines let me know.

The one i have has a plate blocking it off but i did get the lines from a hiace CT20 and they bolt on.

The plate is located next to the heat shield on the otherside of the "CT20" words. So look at where is says CT20 on the turbo and then follow it over the pipe to the otherside, you will see a plate with two bolts on it BINGO

Sorry to barge into the topic. I just acquired a Hilux 3L with a turbo kit of some sort. Either AXT or Safari.

The power is reasonable but it's the response is quite dissapointing. Lacks throttle respone on 3rd and 4th. The mid range and low end feels kinda lethargic and the engine feels abit rattly and then top end it starts moving.

I'm clueless on how to tune it and i've done my fair search on the forum.
So how do i play around with the fuel pump? Apparently my car fitted with and anaroid pump.
Is this article applicable? Is this how u adjust the fuel pump on my Hilux the same way as a TDi? http://www.outerlimits4x4.com/PHP_Modul ... hp?t=35657

Also my car seems to have some over heating issue. When i really floor it above 110kph and to the indicated top speed of 160 the water temp goes up from half to 3/4. Dont tell me i need to upgrade my radiator? Could it also be my charge cooler overheats due to heat soak?
Any advice appreciated.
Help....
Thanks.

[phippsy]

160 with a turbo 3L mine is screaming it's tits off at 120...

Oh, and I paid someone else to play around and tune the injector pump as well.

[4x4Monkey]

get ya raditor flushed and cleaned
and also get the system flushed and get a pressure test done
and make sure the engine fan is working

and get some decent coolant

[BabyGodzillaGTi-R]

Well i flushed the system for the radiator and charge cooler and there's coolant in it.

Like i said it's funny, when i cruise or pushed the car anywhere below 110 on the speedo the water temp sticks to half. When i push it beyond that the water temp will start creeping.

I'm not sure the speedo is accurate but since it's on punny 235/65 R15 i assume its probably doing 150 actually.

So guys any idea how to i tune the pump myself? Would it be easier if i take a picture of the fuel pump and u guys point to me how to tune it up?

Btw i'm in Malaysia. Not many turbo bolt on conversions here that i know off.

Go do a pump and injector service....your aftermarket turbo could be a CT20 from a 2LT! Or an add on like Safari which are not too common but are around!

[sniper]

What psi are you running? If you dont have a boost gauge get one. My runner 3L is on 10psi and i stay with 4.2 N/a cruisers and pootrols and take them on hills. Not as fast as my 4.2 TD 80 cruiser but not far off it.

Havnt had mine till 160km/h but had it till 140km/h didnt overheat though. Would of though 160km/h would be on red line?

Does it over heat any other times except high speed? i.e sand, long big hills?

[BabyGodzillaGTi-R]

Hey GoToy,
i'll consider doing a pump serivce and an injector service as a last resort.
Currently the car less than 60k mileage. Kinda odd for a 15 year old car eh?
I checked it's an AXT turbo KIT. Running a Garret turbo of somesort. Wonder if it's a T25 flange. Get fedup drop in my spare SR20GTiR turbine. I wonder how would that fare.

Hey Sniper,
i guess it should be over revving by around 150kph. My truck doesnt have a rev and a boost guage. Well i'm currently running 4.5 diffs and 235/65 R15. Not sure how to do the rough maths.
It starts to overheat when i do highspeed runs on the highway. I wonder if it's anything to do with the heatsoak of the chargecooler or just bad tuning?

Btw i took a picture of my fuel pump. My mech adjusted something as seen in the pic on the left by sliding it to the end of the plate. and that suddely gave me all the desired topspeed. What i would like now is to sort out the lack of throttle response. Can anything else be adjusted? Btw what sort of AFR do diesel runs?

Do you really believe that? Mine is 16yrs and its half way around the clock. Garret turbo...quite nice.

[BabyGodzillaGTi-R]

Any idea how would an SR20GTi-R turbine fare on the Hilux or it will be quite a laggy match for the 3L engine?
Some specs off the net:
Comp Trim: 60
Comp Inducer: 46.6
Comp Major: 60.1
Turbine Trim: 79
Turbine Major: 53.8
Turbine Exducer: 47.9
Housing A/R: 0.86

Me and my silly ideas.
Hope some one here can shed some light on tuning 3L engines. I'm clueless about diesels.

Gotoy,
yup ROFL, the car been with us since day 1 and hardly been used. Surprise, surprise. Best bit, after the goodies went in, has never been offroading since. So that's like a good 10 years ago or more. Silly eh.

[BabyGodzillaGTi-R]

Any opinions and advice from the floor?
Cheers

Hi, i have a 2.8 3L, i got mine turbo'd about 6 months ago by a place called turboglide. The kit installed with a 2 1/4 exhaust, dyno'd, 2 years unlimited km warranty, with a garrett t25 ballbearing turbo only costed $3270.
The turbo is running at about 9Psi and is tuned to 30% increase, they advise that 30% is not to be exceeded, they say (with proof) that it increases engine life due to lower oil contamination, any more and they reckon it'll kill the engine in a short period of time.
You can really feel more power, and alot more torque, it is heaps better off road especially on steep rocky hill climbs.
Because it is a ball bearing turbo it spools up very very quick, you put your foot down and it only takes a few secs to hit full boost.

Mine gets around 100kms extra per tank unless i floor it every where, with nearly no black smoke, it was installed at 200,000 ks and now has 220,000kms, it is very smoothe and performs really well, if you intercooled it you could run 12psi and it would run even better (an extra couple of psi wont make that much difference in engine life)

Look at the site turboglide.com.au

make sure you don't use a tdo4 turbo (from mitsabishi and arb kits), they are very small and the heat of em eventually cracks the turbo,
By the way My turbo is oil cooled, water cooling is not needed diesel exhaust temps do not get high enough to require water cooling, as long as you don't stop after full boost and switch it off, have to let it cool down, bonnett scoops are good for that...

Thats my 2cents worth

later hope it helps

how is the 3l (not 2.8) hilux motor in reliabilty and how many k's can i expect to get out of one befor things start to go wrong, also dose it have enough power to pull throo soft sand and hold 110 uphills along the highway.
it's either this or a v6 or 2.8 triton duelcab as it will be mainly used onroad driving.

[4x4Monkey]

ok i take it u have note even looked at this thread
so i dumb it down
3l motor - moped + hill= moped coming over hill fast

tho 3l motor 300 000km = still going strong
triton v6 100 000km= things start to go down hill

hope thats made things easyer for ya

[sniper]

when we say 3L this is actually the 2.8 ltr hilux motor, the 5L is the 3ltr hilux motor

A 3L definetly needs a turbo and around 10psi to conquer a hill at 110kn/h, so does a N/A 5L.

[BabyGodzillaGTi-R]

Hey guys i'll appreciate if you could share with me how to exactly toy around with the fuel pump? Coz my bottom end, mid range feels crap, but oddly the top end feels nice and likes to be reved on my 3L turbo.

This is a pic of my fuel pump. Any idea how to tune it?


Also if i fit a GTi-R SR20 turbine would it be ok or way too laggy for road, offroading application?

[bribiesurf]

I have been stuffing about with these L series engines for a few years and the chepest reliable mod is to see if you can check with wreckers etc and trading post for a complete 2LT II with a cracked head(the most common fault in surfs), these are the manual surfs from 1989 to 1993, generally about $800 complete, so you have all the gear to do the job properly, sell off bottom end (fits normal hilux 2.4 2wd) keep ancilliaries for yours as spares, easy id is the non efi pump with the TPS on the throttle shaft and the aneroid on top.
Standard they go much better that the NA 3L, the best mod is a 2.3/4 straight through exhaust with very little bends, a bloody decent radiator, then stuff with the boost etc, a good steady 10psi is perfect 12 with intercooler, this gives best reliability.
Best tuning investment is a pyrometer and 1 hour on a good dyno, the pumps are quite straightforward, basically setup your non boosted fuel loads idle and full rpm, then connect it all up and do your boost loads, keeping EGT under 500.c, you can get a VDO gauge for $280 but a thermoscan or thermocouple on a multimeter will do. Easy diesel thing to remember, black smoke is unburnt fuel which is also heat, they don't "lean out" like petrol if set on the lighter side, they just don't develop extra power.
If you are goindg to do conversions etc 1KZTE best bang for buck, lexus v8 and comm v6 is good but $$$ no matter what anyone says, or just buy a 5L ute

A T-25 turbine would probably go well as this is suited to a 2.0 SR20, and your putting in on a 2.8 2L, but would you really bother? These motors wont handle anything much past 10PSI, especially at the speeds your talking about, without Intercooling, pump and injection mods.

If your really want to cruise around at 160km/hr all day in a lux, drop the SR20 motor in there from a GTiR

"Tuning" of your pump is a hard thing to do with in on the truck, all you can do is adjust the amount of fuel delivered, and maximum velocity (max rpm). You can add more fuel, but you will run the risk of destroying pistons from overfuelling at low revs as you fill the combustion chamber with fuel that cant be burnt, and create a black smoke screen behind you.

The best thing for you to do would be to get a boost compensator fitted, this will imporve your bottom and mid range because it will adjust for fuel delivery at lower boost pressures, the reason it goes so well at 3,000+RPM is because its being fed 10PSI of boost.

Yes, these motors love to rev, it should happily see 3,500+ RPM given its age, and you use good quality oil and filters every 5,000km.

So, to conclude... dont try and play funny buggers with the pump in your driveway, take it to a diesel workshop and get them to put the pump on the etst bench, tell them you want max power and they will re-time the pump and adjust the fuel for your properly!
