Mac#1 Motorsport Worx Build
Discussion
Sealer was applied to the lower engine casing and then the two were put together, bolts/washers fitted and torqued, then the generator, clutch, oil pump, water pump etc were fitted.
Sump finished and fitted.
The next things on the to do list are the starter motor and it's gears/covers, then the timing chain and cylinder head.

Here's a small update, I got the cylinder head and cams fitted, then timed it all up.
The old exhaust manifold wrap was very flakey and had started to fall off so I removed it to start again, but found the manifold had cracked in numerous places around the collector, doh! It's since been repaired and is ready to go, when I get some free time.

Really nice build.
I think a motorbike engine is a car is good fun
but a turbo bike engine! Nuts
That sump is very tasty
Thanks very much :-)I think a motorbike engine is a car is good fun

Any more updates?
I forgot to update this thread a while ago, the manifolds were fitted to the engine, engine put in the car, exhaust fitted and everything plumbed in.Today the weather has been canny so I've had the car outside on the drive and got the engine running, nice to hear it again :-)
I've recently had some work done by Damien at Daytuner, i'll post more info and photos of those things tomorrow.
Today I took advantage of the nice weather and bonded mesh to the bonnet, here's the finished article
I also cut 1/3 off the bottom of the intercooler to allow more air to the radiator, when at steady throttle on hot days the water temp was reaching and settling out at 102 degrees C but the inlet charge air temp was 37 deg C max, around 5-7 degrees over ambient air temp, so it looks like the cooler is more than up to the job, hence deciding to reduce the size a little.
Here's how the intercooler currently looks

While the car was at Daytuner the following things were carried out,
Fuel injectors cleaned and tested.
A charging issue was rectified.
Power Commander and all associated wiring sensors removed.
MBE 9A4 ECU and required sensors installed and mapped.
MBE 995 dash display fitted to the steering wheel.
The Davies Craig water pump, radiator fan and turbo cooler fan were all wired up to an ECU output to allow them to all run according to temperature, the water pump also runs on after ECU turned off to aid turbo cooling.
Here's the MBE 995 dash display fitted to the steering wheel, it displays gear position, boost/vacuum pressure, coolant temperature, oil pressure, RPM, air charge temperature and battery voltage, it also has shift lights at the top and warning lights at the bottom.

Yesterday I got on with modifying the intercooler.
I made an aluminium plate to seal the bottom of each end tank, they were a snug fit so they pushed nicely into place, here's one in position
Welded up, not perfect welding but I'm happy my TIG welding is improving
The finished intercooler
With the mesh in the nose cone removed, you can see how much more radiator is now exposed
The car was built back up and taken for a test drive, it was a scorching hot day, water temps maxed at 90 deg C while driving and 92 deg C in short traffic jams, air charge temps were around the same as before maxing out at 39 deg C.
All in all I'm really happy with the days work!

Tested the new sump modifications out the other day, gave the car a good run out, everything appears well, no leaks, oil pressure looking good etc.
Unfortunately later on the car began smoking, mainly as it came on and off boost, the turbo was the most likely cause but further investigation was required.
A compression test of the engine showed 155psi on all four cylinders proved the engine was ok.
Took a boost pipe off and found oil inside, then took the K&N off the compressor housing and found oil in the inlet!
I've been in touch with Owen Developments today and I've bought a GT3071R core with metal bearing cage upgrade and a new ported compressor housing as my current on is too big, i'll install that core into my current turbine housing before fitting to the car.

It's seems to be fighting you all the way.
Lets hope this is an end to it!
Aye it certainly is, hopefully thing's get easier now!Lets hope this is an end to it!

Please don't take this the wrong way because it looks an awesome bit of kit and I've been nothing but impressed with the standard of your work, but at any point have you regretted going the balls to the wall turbo BEC route?
It seems to have spent more time in bits than on the road
Feel free to speak your mind, as long as it's genuine/constructive I've got no issue with that.It seems to have spent more time in bits than on the road
I actually enjoy tinkering and modifying the car, not so much repairing it though! The thing is, you only really find out if your one off parts/modifications really work once you put them on the car and drive it, consider the time/money mainstream manufacturers spend on research and development, and also the fact it's running 300-350bhp per litre, you have to expect/accept a portion of failures/hiccups during the initial running in period! Hopefully most of mine are behind me now!
I don't regret going the turbo BEC route at all, I've been in a few standard BEC's and although they are quick they just don't give you the attack on your senses that my car does. One thing I would change would be to go for a Hayabusa Turbo if I wasto do another turbo BEC, the reason being they are just so well catered for in terms of aftermarket parts and experience, you're spoilt if you have one.

Totally respect what you are doing, I`m in a development phase with mine as well. It`s all working well at 1.3 bar now and am currently having it dynoed for an AFR and coolant temp check. It should really be at 2.3 bar and around 500+ bhp but it`s so damn rampant at 1.3 I can only imagine what it will be like with the wick turned up. My problem is I don`t have the apparent skills you do so it`s expensive on the labour front.
I have designed a new charge cooling set up which whilst it won`t win any beauty contests will hopefully build some safety in.
I`m looking at doubling the size of the chargecooler core and more than doubling the size of the pre rad, which is already large as pre rads go. I`m taking it out of the front of the car and relocating it in the rear, either inside roll bar hoop at an angle or in place of the rear "parcel shelf" with fans to pull through and a scoop to ensure adequate airflow.
This will increase airflow to engine coolant rad as well although I don`t seem to be having probs in that area. Turning up boost on 7-alikes can just turn them into heat pumps!
I'e not seen your thread on Passionford lately, are you still keeping it up to date?I have designed a new charge cooling set up which whilst it won`t win any beauty contests will hopefully build some safety in.

What power/torque is your YB making at 1.3bar?
Do you have any figures for your current water/air temperatures?
With regards to your chargecooler, function over form is where it's at, once you've proved it works reliably then you can make it look pretty! I've got a turbo cooler rad in the parcel shelf area, if you don't have a solid floor on the diff area of the car it gets a decent amount of airflow, I'm tempted to fit a solid floor and then duct the rear rad sometime in the future.

great work.
i follow the thread on afew forums locost builders, passionford etc....
ive also had smiliar issue in regards to turbo faliure and cooling in my 7, ive just fitted a turbo cooler and pump to mine after my turbo went after 200 miles!!!
Thanks very much for following the cars progress.i follow the thread on afew forums locost builders, passionford etc....

Do you have a build thread on your car? I'd be interested to see it if you do.

Great stuff, i'll have a read through that tomorrow morning with a cuppa This afternoon I removed the turbine housing from my old turbo and gave it a clean up, here it is alongside the new GT3071R assembly
The up pipe from the old turbo compressor housing was cut off and cleaned up ready for welding to the new compressor housing.
Here's the new GT3071R, the old GT3076R and the up pipe
I didn't take anymore photos today, but in a nutshell the turbo has been refitted, along with the exhaust, coolant hoses and oil hoses after priming the turbo with oil.

Here's a little update on why the car has taken so long to get sorted.
With the house extension plans for the rear ground floor and front garage extension approved building work commenced.
The external shell built up at the rear of the house
This wall needed to come out and a supporting beam installed
Wall removed
Fish tank stand built and installed
Fish tank built on site
Kitchen arrived in millions of boxes and filled the front garage extension
Old kitchen removed and the room plastered
The finished fish tank wall
And the full kitchen
Garage was in a right state and certainly needed a good clear out!
Clearing stuff out made the garage look so much better and actually helped me relax a bit, it was awful seeing the place in such a state!

Right then... I finally found time to get around to looking into the issue with the cars engine, it was running on three cylinders.
Compression testing the engine returned the following results
Cyl 1 = 140bar
Cyl 2 = 140bar
Cyl 3 = 140bar
Cyl 4 = 0bar
Which was certainly worrying!
The car wasn't smoking (aside from the unburnt fuel), pressurising the cooling system etc, externally everything appeared ok, so the engine needed to come apart.
Engine out
Manifolds off, couldn't tell anything looking down the inlet or exhaust ports
Even with the head off there wasn't much evidence to see, looking at the combustion chambers on the head the valves/seats all looked to be in good condition and not bent/damaged, but the pistons crowns had slight marks in the valve cutouts, indicating there had been piston to valve contact.
Removing the cam followers revealed an issue on cylinder number 4, one inlet valve and one exhaust valve had collets out of position, presumably caused when the piston to valve contact happened.
All of the valves were removed, inspected and found to be straight (surprisingly), they were then lapped in, cleaned up and the head reassembled. WD40 poured into the ports and left, no leaks observed so it was cleaned up ready to be installed.
The head was then installed using a 0.027" Cometic MLS head gasket, same thickness as standard Kawasaki gasket.
The cams were installed, timing set and valve clearances checked, all within spec so no need for further adjustments.
Engine back in the car, ready for the final pieces of work to be done prior to getting the engine started up.

Is that new gasket thicker than what you were running before then?
Unfortunately I can't say, I can't find any evidence of which gasket I bought and fitted last time, I know it was a Cometic MLS one but they do 3 different thicknesses, I tried measuring the old one but didn't get a definite reading, a thinner gasket last time could possibly account for the piston to valve contact.Yazza54 said:
