I take it that the turbo is moslty responsible for the 2 -lt surfs overheating and their fore cracking heads. My question is probably a silly one, but is it possible to disconect/ take off the turbo?? Or is the whole engine set up for the turbo? This would reduce the risk of cracking but would make it as gutless is f#*k.
Can anyone inlighten me???
cheers.

Sure you can. But no turbo isn't a guarantee that you'll be safe from the cracked heads and such.
The best plan for longevity would be maintaining your cooling system and driving it gently. A healthy turbo engine runs cooler, cleaner and more efficiently than a non turbo engine putting out the same power.
Shes a manual.
Oh righto - yea that makes sence, yes i do drive it very easily (im a nana aparently lol)
So maintaining the cooling system - the raidator and antifreeze etc??
Just been reading all the horror storys about 2-lt surfs and looking on trademe, alot have and their heads replaced
im a poor student with bugger all money

I've been there, trying to fix up a vehicle and keep it running while at uni. Just avoid the temptation to do really really dodgy fixes to get through. Sometimes it's better to walk everywhere for a few weeks so you can do things properly.

cheers - yea ive sorted out a radiator cover for the mud and often check it.
Its going no worries at the moment but with toyota surfs history you never know when the worst can happen unfortunatly, and I cant afford to do a engine job at the mo.
Would fitting a boost guage and or after market temp guage be advisble for these surfs?

For what it's worth
The issue with auto's was the oil cooler that is in the radiator not enabling as much circulation.
Put a Bigger exhaust on it and it'll do alot better. Remember these motors can cook heads without even overheating on the guage, simply from heat not getting away from the head and restriction in exhaust.
And it'll probably do it to Manuals just as likely.

save your coin on buying a boost gauge ( unless you wear your baseball cap backwards and wear your dads pants) as its not going to effect the temp but the in dash factory gauge is sh*t. Fit a decent temp gauge. Ripco are selling a sender unit fitting that fits into the radiator hose. The Toyota in dash gauge is just too dam slow and the engine would have melted to a pile of crap by the time the gauge has reached hot.
2.5 inch exhast seems to be the general replacement size and price depends on who you get. Shop around for the best deals
A cheap uni student trick (i did this to mine when i was at uni) if you can't afford to get a 2.5" exhaust system fitted is to shorten the length of the exhaust, which also helps to get rid of heat quicker.
I pulled all the silencers out of the system and using the rest of the exhaust i had cut out, made the pipe exit just in front of the rear wheel on the passengers side, it is/was legal as its within the correct distance behind the rear most opening door apparently.
Just make sure your cooling system is squeaky clean and as good as it can possibly be, fit a aftermarket mechanical temp gauge to the drain plug on the side of the block, and make sure you ALWAYS let the engine idle down for at least 3mins just to be safe.
I sold mine with over 250,000 of well thrashed K's on the clock and all that was wrong with it engine wise was a dribbly injector.

Yes definitely.
Exhaust temps are IMO much more important than coolant temp. An EGT gauge can easily show how much load you're putting on your engine and also when it's safe to shutdown.
It's a very expensive item for a uni student though.
been down to t exhaust shop in Dunners and it will be 650-700 for a 2.5 inch from the turbo. aparently will go better and better fuel consumption too
Looking at temp guages also - ranging from 70 to 160ish dollas, but i think it will be worth it.
Is there any more info i should know about the cooling and maintanace ectc of these surf engines??
Failing that I could always sell it... lol but what to buy...

A pyrometer (EGT gauge) isn't $70-160 dollars, they're more like $300-1000.
Here's one mailorder place that could save you some bucks. I haven't bought from them.

The EGT (exhaust gas temp) gauge if used properly will make your engine last longer than any of the above mods.
It's also something you can keep when you sell your surf and trasnfer to any other diesel. A 2.5" exhaust isn't.
Took a look at the web site, cheers, your right though very expensive.
Yea i was looking at standard (aftermarket) temp guages for with one being 160 from mag and turbo - are these worth while? as mentioned aparently the standard toyota ones are shit? im not sure, however have been advised to fit aftermarket one. however as noted exhaust temps are more important that radiator temps
How does the EGT guage make your engine last longer? sorry prob stupid question but I dont know much about them EGT gauge show how much load you're putting on your engine?
cheers, very helpfull as im still learning

oi tomo m8 when are you going to come and hit up some bogs. how about tomorrow late afternoon? yea fair enough trying to stop your surf from cracking a head. byrnes isnt looking to good. blowing white smoke all the time now. manuels crack heads to i know atleast 4 people who have cracked them. so you drive like a nana boss.?? nah just joking. shit shes a mission working out what to do with the surf ae. so many mods to choose from. what you got planned. ??

The EGT gauge gives you the best feedback for exactly what you're doing to your engine. With a diesel it's still possible for the fuel pump to be putting full load on the engine when your foot isn't hard down. An EGT gauge shows you exactly what's going on.
In a nutshell, higher engine loads = hotter exhaust temps.
It can also be used as an economy gauge, showing you basically how fuel you're burning and how changes to your vehicle (tyres etc) affect engine load and fuel economy.
I'd pass on the aftermarket coolant temp gauge. A factory one that works is all you need, if the needle rises past normal then something's not right.

how about sunday around lunch? got work at 3 ae - been busy as hell tryn to earn a few dollas. As far as mods go im loking into guages. But a snorkel and lift kit in the back and winding up the torsion bars n the front should be the ticket.
found one on trademe : http://www.trademe.co.nz/Trade-Me-Motor ... 092640.htm
Have a look if you have a spare min. Would instructions etc tell you how to read them? these ones range from between 300-1200 degrees by the looks of it

surf_tomo wrote:cheers for the info about the guage, and I will definitally be looking into this further. thanks heaps.
Have you bought one from NZ? or you recon the mail order may be the way to go.
It looks like very inportant info to know about the engine
I got a VDO EGT guage from TWL in Dunedin. I got an excellent deal from them, but for most it's cheaper to buy from overseas.
Mine is in Celcius and goes from 100-900 deg. That one is probably for a petrol engine, the range is higher than you'll need.
My engine runs 400 deg C at 100km/h, 170 deg C at idle and 750 deg C is your dangerzone.
You'll put your own safety factor on that number.

This brilliant forum thread (link below) will tell you why the factory gauge in the surf will NOT tell you when your engine is overheating. This 'design feature' in Toyota temp guages has cost me two Surf engines, two Supra engine rebuilds and last week a new surf head ($3,300NZ inc parts and labour). It takes a while to read all four pages but these guys are knowledgeable and love their surfs. I've been reading this thread on offroad express and have just signed up so I can tell you guys to read it. Get an aftermarket guage and sender for $35 (Delta 4wd in Blenheim for mine) and save yourself 100 times that in a cooked engine. You don't need to do the circuit board mod they describe, though I'm thinking of doing it this weekend. You can buy a sender fitting kit (alu collar thing) off trade me for $20 and fit the sender to a hose.
Also spending $450 for a 2.5" exhaust (Murrays Mufflers (Blenheim)) which apparently is a very good idea. Looking for 8 blade Land Cruiser fan too, as long as it's not expensive.
Take time to read it, it is worth it.

thanks for finding that info its a far cheaper mod than a EGT gauge and a hell of alot more user friendly, Most peps can read a temp gauge where is you would have to retrain every other driver with a EGT Great tuning tool but thats about it . for the price of an EGT you get an exhast , water temp gauge and a land crusier fan.
good one

A bigger exhaust is not a substitute for an EGT gauge.
