desert spec engine

[pjm300]

right.

i need a 1 litre (ish) give or take 100 cc engine which is gonna be reliable, and last 10000 miles of abuse.

what do people recommend?

will be in north africa in their "winter" im not bothered about the europe bit as it'll be fricking cold there.

1.1mpi?
1.0 carb?

what do you reckon?

oh, and its got to run on leaded petrol as well as unleaded.

discuss

[Aron]

i would peronly say carbs may be a bit better for maintance reason on it.

the 1 litre part makes it a bit harder though, maybe an old rover engine, where always reliable

[pjm300]

its gotta fit in an ax ;)

[LeeM]

how about a 1.1 with open throttle bodies? should work well...

[raunchz]

1.1spi?

plenty of air and fuel filters - should be a bomb proof engine :P

[Aron]

open throttle bodies, title says desert? bit risky

edit: or is it suppose to say descent?

[VtsTom]

Id stick with the pug/cit 1.1 spi. Fit a bigger rad and twin fan combo for the heat though

i was trying to make a funny lol

Leaded fuel doesn't work with cats and lambdas so that kinda rules out SPi unless you were to fit a dummy lambda in the form of a variable resistor to adjust the fuelling.

As per our convo i think carbs are the way to go, the carb will need a full rebuild and you'll have to make a custom air filter and clean it regularly.

Keeping those alloy block engines cool is very important.

[pjm300]

yeah you got me thinking last nite alex.

so if i keep the 1l ax engine, give the inlet a thorough overhaul, learn how it all works etc, make an inlet from drainpipe with multiple filtration going to a low pressure point on the body, that should be ok?

vts rad with twin fan housing, one on a direct switch on the dash a la spaxo engine

maybe 2 water temp gauges, or one water temp and one oil temp?

Didn't think about the leaded fuel - my bad.

Would it be worth taking a spare carb along with you just incase?

i think there'll be a roof rack full of spares :D

sounds a good idea. learn as much as possi ble before you go.
putting a switch on the second fan would be a good idea.

consider oil cooling aswell. insane heats over there.

[pjm300]

its going to be "winter", so probably only mid 30's :D

[Matt67]

are you doing it by yourself? or what are your mates taking?

[raunchz]

poor little ax !

[AlexR]

Mid 30s is still a lot for an alloy block TU.

An oil cooler will cool the water too. A heat exchanger will probably do quite well though if you have a good water cooling system, should keep the oil cool too. Cooler stat or possibly no stat.

Have an override on both fans, all you have to do is switch the earth anyway ;)

haha i am sorry!
ok your oil will boil in 2 hours instead of one!

what are you doing this all for anyway?

there's 2 of us in this car, i think there's about another 4 other cars going

can the vts heat exchanger go on these engines? they just fit beside the oil filter anyway... havent seen if the filter is in the usual location...
i'll have a good poke in the bay, there's plenty of space there, so some bonnet bodgery might help to get some heat out :)

its the africa rally, charity event from the same people as the rickshaw run and such like

london to cameroon in december

[Aron]

that would be awesome.

heat exchanger would fit mate i would of thought.

[Sophia_Bush]

heater exchanger will fit just make sure you get the threaded tube n hose.

VTS/GTi/XSi rad will fit fine I fitted one to my old blue ax bit of cutting slam and it was in. OR go for a diesel rad and header tank setup much easier for you to bleed the system then as it is near enough self bleed.

With that and a good fan mine always ran just below half and never had problems.

Carb wise remember the 1.1 carbs fit to

[pjm300]

think i might have a spare heat exchanger lying around in the garage.... wahey :)

think the rad is something i need to get new. will see if i can get a discount from somewhere... probably not :D

Buy a nissems from the buy & sell section :y:
