Hey John
check Strona g, might be another cheap option for you

First up, an oil filter pedestal adapter. This gives me something where I can mount an oil line, and it also holds the oil pressure and oil temperature sensors.

Here it's mounted on the engine, this also shows the coils in their position:

1) When will you begin sales of your oil filter pedestal adapter block? :nod:
-All the ones currently available are quite ugly, yours ROCKS!

2) What is the make/application of that sending unit that is installed on it in that second pic? And is it the oil-pressure or other? One last question, will it fit the stock location?

Thanks John! LOVE IT!!

Omg, you're skill is amazing! I love those headers and throttles! Keep up the good work john!

damn this is an incredible build, a true work of art and engineering genius. i cant wait to see the fully finished product.

HARD2B 03-07-14 08:45 AM

tag to this pro. build!!

SpeedyRotary 03-07-14 01:47 PM

This build is phenomenal!!! Beautiful build, great work man!! I'd love to hear this beast run on a track!!

evilbloodbrotha 03-07-14 09:59 PM

It's killing me to hear this beast run! Keep up the immaculate work!

John Huijben 03-10-14 06:32 PM

Just putting some stuff in there, Loads of room to work with :)

Then I thought about adding a heatshield between the exhaust and the intake runners, so I did

Didn't take long to make and mount, and it's nothing fancy, just some 2mm aluminium sheet, but I think it will help.
Got a nice box with ecu and wiring stuff in today, so I can start making the engine wiring loom :)

Looks sooo good, just like that.

SpeedOfLife 03-17-14 09:46 AM

I can't wait to hear this monster.

John Huijben 03-17-14 07:05 PM

Yeah me neither!

More work has been done, a little bit in here:

https://lh5.googleusercontent.com/-v...o/CIMG4020.JPG


But I spend most of my time underneath the car, the driveshaft, diff and axles are in place, and so is the exhaust and the mufflers and stuff. Then I started messing with the interior, the stock steering wheel wasn't really cutting it, so I got a sparco one but it didn't fit the stock hub. I probably could have bought an adapter somewhere but wheres the fun in that? So I modified the stock one, stock horn still works :-)

https://lh3.googleusercontent.com/-l...o/CIMG3994.JPG


Also got another pair of seats :-), I had a set of red sparco sprint seats, but the red on white made the interior a bit too pimperish for me so I sold those and found a nice set of sparco corsa's. They are a perfect fit for me, and I think they fit the car better. Downside is that they mount on the sides instead of on the bottom like the sprint's, which meant I had to make new seat mounts. I tried making mounts that included adjustable seat rails, but I couldn't get the seats low enough with them so in the end I just made fixed mounts with multiple bolt holes. The seats are only a few mm's from touching the floor, so I won't hit the rollcage with my head all the time.

That's it for now, next up is finishing the cooling system, finishing the fuel system, and the oil system, and the engine electrics!

I am sooo gay for you and this car. loving it!

evilbloodbrotha 03-19-14 01:16 AM

God I love everything about this build haha. More more more!!!!

monty11ez 03-19-14 11:00 PM

I love that switch panel, and those seats. Actually I love the whole interior.

MichelB33FRANCE 03-21-14 12:20 PM

very nice work John !

Just one point about your thermal insulation screen,
take care there is no thermal bridge with the inlet pipes
if not you risk to have the wrong effect

all the best
Michel from France

John Huijben 03-23-14 12:30 PM

Cooling system, check!
I had to connect the engine with the radiator, but with that huge aluminium vent I had to get a bit creative. After some messing with radiator hoses I just got some 38mm alloy intercooler pipes and welded some pieces together. Came out better than expected :nod:

https://lh3.googleusercontent.com/-u...o/CIMG4033.JPG


Next up, wiring!
I started doing some stuff in the back, Made a battery box that sits in the spare wheel well, and added a battery. The starting system isn't really special or anything so far, just the stock starter and an easy to get battery that was slim enough to fit in the spare wheel well. I'm not sure if this can get the beast cranked over well enough but I'm going to try this first and find out. I heard about adding another battery and hooking them up in series so the starter get's 24V's during starting, which might be worth looking into if this fails, but I'll cross that bridge when I get there. Oh, also added a killswitch where the keyslot for the hatch was.

Couldn't finish the wiring in the back because I didn't have any beefy 0-AWG wire lying around, so I got started on the engine wiring stuff that still needs doing. This is the plate that sits in the passangers footwell, it holds a controller for the LSU 4.9 lambda sensor, the megasquirt which I fitted into a rugged waterproof case, and the relay for the alternator. Already added the wires that go between the ECU and the chassis (power, ground, fuel pump relay, cooling relay, tacho ect.), now I need to add the wires that will go to the engine

So close! Cant wait to see this thing driving!

JK5S 03-24-14 01:09 PM

All this car need now is a pair of rubber floor mats and a clutch pedal :)

haza88 03-24-14 04:09 PM

really like this

The manual starter is a 1.2 kW unit with 13 ft-lbs of torque. The Automatic starter is a 2 kW unit with 16.6 ft-lbs of torque. The automatic starter is ~1" longer and will fit in the same location as the manual starter.

Hook them up in Parallel so that you get double the CCA's with the same voltage. It's what they do in light duty diesels.

ZackTheKack 03-25-14 05:59 AM

I so wish I had your skills at this stuff. I'm just learning to tear down, rebuild, and not be terrified of a rotary lol. Great build and can't wait to see and hear it run.

I think it will be better to hook them up in series. and use some logic sense and some relay so they get charged in parralal during driving and switch to series during starting.

adding a batterey in parallel will not do much as the starter with 1.2 kW only draws slightly over 100A at 12v lets say with on battery you will see 10v during cranking and with 2 aroudn 11-11.3v which is only about 10% increase in starter power.

with 2 in series you will see around 20v during cranking which is about 100% increase :nod:

Do you got some pitures on how you made the passenger side seat rail?
