Hey all i'm new here freash from australia
ok heres my idea
i know it has been done before but i was looking for some feedback
i plan to turbocharge my feroza using a T28 or T25 turbo from a sr20
this seems the best way to get more power out of the under powered 1.6
i was just wondering if anyone knew of a turbo manifold i could buy anywhere
otherwise i will make. i plan to run a small intercooler and stainless piping
if anyone has any tips, hints or suggestions i would like to hear em
Cheers Rundle
Blown Away, Hopefully Not Up
Forget it in a nutshell, while the engine is fairly durable it is not designed for turbocharging.
Two options are available, Feroza's were available in Italy with BMW 2.0 petrol engines with significantly more power, try to source the parts ot drawings and fit one of these.
Option 2 is to fit another larger and more powerful Toyota engine, many are available which will fit without much hassle, a complete engine is so much easier to install, plus having a standard unit makes servicing and parts so much easier.
My old F20 had a GM 6.5 litre V8 supercharged diesel in it, this produced 300BHP and was phenominal, bear in mind that i have a lifetimes experience, and access to all the equipment to undertake these types of work.
Toyota developed many engines from the same 2.0 litre engine which was fitted into some variants of your vehicle, some 8 valve, some 16 valve twin cam, and many sports variants, most will even fit your gearbox.
Do some research into your local vehicle market, you will almost certainly find a good powerful engine which will fit with minimal problems.
Feroza Turbo
Hi Assassin.
There's no telling these sheep shaggers.

Sheep shaggers are from new
Sheep shaggers are from new zealand not Australia. Pal!
and the mods that you have done are...... didnt think so!!!

WHATEVER PAL!
Whatever PAL, whatever. I restore and tune Mini's but know the problems that putting Turbo's on to these can cause long term on reliability. Just can't see the purpose on a Feroza and would rather tune the suspension for offroading if I were that interested.

Turbo
Turbo's are called blowers for a reason, done incorrectly they blow the engine up due to too much compression being developed in the engine. Turbo conversions need careful consideration of every aspect of a conversion, perhaps this is why engine designers and manufacturers spend £££millions on developing and testing engines.
As for not knowing what am talking about, Cosworth DFZ Formula 1 engines developing 1500 BHP, from 1500cc; DTV rally engines producing 475BHP from 2 litres, and many more turbocharged engines i have worked upon. Has it not occured to you that we do know what we are talking about, as oldminiman and Nev K also agree, so do they.
If you would like to compare mechanical qualifications, and experience i would be only too willing to oblige.
I am as likely to
I am as likely to turbocharge my Sportrak (Feroza to you guys) as am to saw my own legs off with a blunt saw and no anasthetic, but I do recall somewhere back in the very dim and distant days of this forum someone saying he had fitted a GM family II 2.0 turbo (Vectra, Astra) without much difficulty (or so he said) and then mailed me the pics.
IIRc it was a good conversion, and he did this after deciding the blowing the original was a no-no if you wanted reliability...

Well Said Dave
Saying you can do it, and actually doing it is two different things, as you have said he claimed he did it, but did he say how much it cost him to have the engineering work on the engine done. Without this the engine would undoubtedly be unreliable as the first time he floored the throttle pedal, something would give.
It comes down to horses for courses, sports and performance vehicles have the brakes, suspension, and other engineering aspects modified for their performance. Off road vehicles do not need high revving engines, they need constant low and mid range torque, and reliability, the AA and RAC do not recover from 20 miles down a green lane, or half way up a mountain side.
Hello every one. The turbo
Hello every one. The turbo conversion that i have done was done by me. I made all the components myself. all up this cost me bout 5 grand Aus. I rebuilt the engine with cast pistons not forged. ceramic coated them also. standard rods were shot peened (they are pretty weak looking and small.) Standard head gasket and same 9.5:1 compression. I have added a front mounted oil cooler instead of the water/ oil cooler. limited the rpm to 6000rpm so far this combo has held up. i dont thrash it too bad .
to assasin. is it better to have a n/a camshaft for turbocharging or have a custom one made. I have got one that has higher lift but less overlap . it feels torquier but not as rev happy as the stock one. maybe you could share some experience here?

Experience
My experience tells me that running an engine with a 9.5-1 compression ratio with 10psi of boost will be running compression figures of that of diesel engines, having calculated it out, and with the modifications you claim, the engine will grenade itself immediately.
Therefore your camshaft question becomes irrelevant.
Um how come i can drive it
Um how come i can drive it day in day out 10psi to the redline and have had no problems then???
there are cars with much higher compression than 9.5 and run more boost yet they are ok still??
surely you have played around with different cam profiles with turbo stuff?

What Have I done
What have i done, worked on Cosworth DFZ formula 1 engines, introduced the taper bore system for improved power, only used by every formula 1 engine made. Won formula 1 championships for several years, forget Ferrari, they could get nowhere near these engines.
Formula 1 engined Escort van, fully road legal and detuned to about 650-700 BHP.
Developed BMW UK touring car engines, won two consecutive championships after BMW Germany pulled out.
Developed and fitted 300 BHP GM 6.5 litre diesel engine, supercharged it and fitted it into Daihatsu F20, just for my fun to blow the Land Rover boys away.
Led the largest private development of bio diverse fuels in the world, and in my own time as a contribution to motoring.
Developed the early turbocharger systems to the state they are today, not the unpredictable entities they once were.
Just some of what i have done, there are many more; now let me throw your question back to you, what have you done?
Silence? Any veiws

Dude Im really happy for you
Dude Im really happy for you that you have acheived all those things. but if some one else wants to have a go at turboing their feroza .... let them have a go at it.
it can be done if thought out and planned correctly.
i hope your escort gives you lots of joy .

Escorts
Escort was a lunacy project many years ago, and no one is suggesting that you do not undertake a project such as this, but belittling others, particularly when they have considerable experience; does your cause no good. I, Nev.K and Oldminiman, to name a few on the site, have considerable experience, this means that we know the pitfalls and the problems you will encounter.
Asking for advice is one thing, but it is a question of learning from our mistakes, undoubtedly we have all learned from these mistakes, and usually on the pocket; this is why we share our collective experiences. This is where the planning happens, it accounts for the fact that many of us are experienced engineers, and know about turbocharging vehicles. If you do not want to learn from our mistakes, it will undoubtedly get you into the same costly remedies we have all had.
Just to say I agree. No one
Just to say I agree. No one is saying don't do it. We are all working from our own experiance and (some times) costly mistakes. I, personally, am definatly of the oppinoion that fitting a larger engine would be safer (and probably easier) than terboing what is already there. The drive chain on a Forenza is still a bit of mistory to me strength wise, but from exstensive experiance of othe Daihatsu 4x4's I'd hazard that it will put up with more stick than the standard engine will produce. The engine it self though is prone to cracked heads and blown head gassgets as it is, without trying to make it work harder than the designers had in mind.

Do you know why these
Do you know why these engines crack and so on?
I have noticed that some of them have a water/oil cooler on them. Is oil temp a contributing factor? i went and got an oil cooler from PWR in Aus and mounted it in the air stream out front. its got to be better at cooling than having heated water running through the stock one. Any ideas??.....

Sorry, I only know that they
Sorry, I only know that they are prone to it from the plorethora of people who have sufferd from said. Personally I have only been playing with Sporti's for a limited time. You may want to ask some of the people who have had this problem the same question? Do a few on site serches, and you should find quite a few. All I can say for sure, from my own experiance, is that they are prone to it...

turbo setup
Hey Dude . dont listen to him... what would he know ??
I have turboed my feroza using a t23g from a s13 sr20det
standard internalls running 10psi. made 122.5 kw athe the rear wheels. is reliable and have not broken any driveline bits. you do need to respect it though. now is heaps of fun to drive. check out cardomain.com and do a search for turbo feroza. its in there have a look.

This sounds like a very nice
This sounds like a very nice project on paper. I am a great beliver in it being possible to put just about any engine into any car (space allowing) with an angle grinder and a welder. However I would be more than a little worried about the strain being put on this engine. I think the resultant creature you unleash would be fantastic, (even better with nitrox), right up to the point when the head split in half. Unfortunatly these engines have a bit of a habit of cracking heads under normal usage. I must agree thearfor that putting a compleat larger engine in would be prefurable. The US Rocky is the same car as the Forenza with a 2ltr driving an auto box for instance.
What about a V6 or V8 of some kind? 3ltr upward? Use a remote transfure from a G-Wagon (Merc) or the like, and any rear wheel drive engine and box becomes a fairly simple excersize to fit. Don't know just how stronge the Sporti banjo type diffs are, but if they are even half the strength of the 4trak they'll handle plenty more than the standard engine will throw at them.
Some of the best fun off road I had was in a 3.5 V8 married to standard F50 everything els. Seriouse kick in the pants.
