Water injection installed, one cylinder only!
Just trying a few teething runs on my turbo install to see whether it is working, and trying to get some kind of tune together (Megasquirt and Lambda
probe allows "home tuning" .
Stopped for fuel the other day, but struggled to restart and flattened the battery.
Today went out and temperature gauge when super high (120degC). Only going around the block (my AA cover is good for 10miles from home!), so managed
to get home, but lots of water loss, and plenty of steam. These engines are based on air/oil cooled motors so a bit of heat isn't as serious as
on some of the more modern stuff.
Head gasket has gone on cylinder 1 according to the plugs. This probably also explains why the lambda sensor has been temperamental (steam and
antifreeze probably upsets the poor thing). When I put the engine together I did reuse the old head gasket (yes I know false economy, but they are
£40 and it looked alright!).
This isn't really a problem as this engine is high compression (not appropriate for turbo), and already has a serious oil leak to the outside,
and was losing some oil down the valve stems. So really it was being used as a test engine. I have a couple of other engines kicking around, so I
guess I will have to order some bits and book some kitchen table time and try my hand at build a nice one from all the decent bits! Just need to work
out which bits to use. I will buy a new head gasket this time, and drop the compression to 9 or so.
Just as the sun came out too!

Hello Matt !
I am new registred on the site, although i have been reading here for long now... I also went over your blog where you've put the build of your
car, because i am going to put an oilcooled 1100 GSX-R with EFI in a french little car  I must say your work is truely amazing. Even if you went
through lots of problems (like the multiple fail at MOT with emissions...), you kept going, great work.
Cannot help you with water injection as i never used one, but a question though : where is the end of your build ?? You stopped keeping the blog up to
date, before putting the turbo on the thing. I was so frustrated ! 
Good luck with the water injection

I am glad someone enjoys my wittering, most of it is badly written nonsense but when I go back to look at it I enjoy it. I have got the turbo
running, although a few teething problems, as you might expect if you have seen the style of my progress
You could look here.
http://matt-phoenix.blogspot.com/ which I am trying to keep up.
Its all nonsense but I enjoy it.
Are you running megasquirt? and whats the car Citroen AX?

The car is a Renault 4 i have used to go to Marocco to eat some sand, with 2000 other french students like me... But 40hp is very very insufficient to
have fun, so i bought a gsxr engine, with a 1216cc kit (12:1 compression ratio) that i'm gonna put in the car.
I've chosen this engine because i ride a GSXR 1100 as a daily and i know a lot of this engine. Besides, as you probably know, it is fookin
cheap, parts also, and very reliable, and that's the most important for me, since i'm gonna go back in the desert with it.
I've gathered all the bits. Now i need to finish school year in a month, to begin the build.
Since the vacuum carbs (OEM) don't like G-force, i also gathered everything to go EFI : GSXR 600 K1 throttle bodies, microsquirt, EFI pump from
a 1000 GSXR K6, Innovate LC-1 wideband lambda sensor...
Here is what the car looks like :
And an another, during the trip :
Can't wait to get my hands in it !!

Don't see many R4's these days.
Agreed the engines are nice and simple, I have got through a few, but mostly because I have bought cheap and generally put fairly broken engines in
which didn't heal themselves!
I see large oil coolers in your future!
Is this going in the front?
One problem that would concern me if I were going into a dessert would be electrical power. One problem with these old engines is that the
alternators are crap (and get worse as they get hot), not helped by adding EFI with all the power draw from pumps and injectors and lambda probe. I
guess solar panels on the roof and a big battery might be a good idea as you could recharge everything while the engine cools down.
Where in the world are you?

I'm in France, near Lyon actually.
I know for the big oil coolers. What i plan to do is to put a big one (or two in parallel to limit pressure loss) on the front, and another one
between the engine and and the oil filter, with a filter relocation kit. I also thought about extending the oil circuit and put another one in the
interior as a heater (it can be around 5°C in the morning in the desert !!).
I don't know which road i'm going down yet. Will do multiple test during the summer, to see how the engine behaves.
The engine is going on the front, and i'm keeping both gearboxes : bike and car, in order to keep the reverse. The advantage is the Renault
engine is longitudinal, and behind the gearbox. So i'm gonna have only to build an adaptor plate between engine and gearbox, and a prop shaft
like the ones i saw on biketransplant.tripod.com.
As for the electricity, i don't know yet what to do. I had in mind to build a new starter cover to be able to pick up the rotation of the
crankshaft with a belt to mount a car alternator that would give me enough power for ECU, fans, but also additionnal lights on the roof.
The idea of solar panels are very good, didn"t think of that ! Gonna have to find myself a sponsor to give them for free.

Nice one.
Sounds like your got it pretty well thought through.
The bandit 1200 alternators seem better than the one on mine. Here are some specifications, only internet, but possibly useful.
+++
General Info
The stock Bandit 1200 alternator has a power output of ~405watts at 5000RPM. This would put a theoretical limit of 405W / 12volts = 33.75Amps.
However; this is *only* if you can keep the bike above 5000RPM. If you let the bike idle for a long period of time with too much electrical drain,
your battery would eventually go dead.

Thanks for the info Matt, will look into these alternators...
By the way, i couldn't find anywhere on the forum a section for the builds only, with one thread by build. Is there one ?
Cheers

No there isn't anywhere on here for build threads as such.
People have run them on here (Cloudy R4 is a brilliant example, but there are other great ones too).
Stick them in a section that you feel happiest with (probably "bec" in your case). The good thing about the recent reorganisation of the
forum is that the recently updated posts get to the top of the lower list on the front page (previously you had to hunt for them).
I'd be very interested to hear how you get along with your plans.
Matt
