Good evening all

Ive been lurking around here for ages, but i thought i might post the build..

My car isnt blessed with the cosworth / RWD pedigree, so its handling is (and will be) a little different. More akin to a tuned golf R32 / Audi. Where the car is FWD, with a little to the rear, until slip is detected and power is routed further to the rear. Hence it will handle more like a FWD.. Sorry- dont hit me.. If it wasnt for having spent alot of money on my engine, and it rotating backwards compared with most other engines, i would be running an MT75, but alas, im not..

I think pictures speak a thousand words so..

I started my Civic turbo build in 2008, it briefly saw the road before the engine (a stock B16a2) gave up.
I decided at that point to do what i always wanted to do and build a B20VTEC turbo, AWD, time attack inspired EJ2. Hopefully ill be able to compete when the setting up is done.




Those pics were taken as the car saw the road with its turbo running. The bonnet was changed for a new seibon OEM item which has oxidised within an inch of its life- i need to restore it soon..

Ill cut out alot of the boring stuff from my other build thread, its a bit tedious..

I removed all the rear subframe, for the rear drive parts;









For the trailing arms i used civic RTSi ones, modified them to shorten them, boxed them in for strength and modified them to fit the crv wheel bearings.








Had to angle the rear strut tops as the struts will now sit slightly angled to the rear suspension











Made brackets for the rear diff






















Installed the radiator and cut open the boot floor to make way for the fuel cell;





















Here is the engine, built by laskey racing in the states in late 2010;







Here is teh B16 head, ported to hell.. its a work of art.. even stamped with the portflow ident..



And now for the block;









Thought id stick the dry sump on, unfortunately needed to modify it to fit past the main girdle;





And finally the new driveshafts




Installed the front coolers;






Since i was doing an engineering degree on day release, i got them to let me do my own project. I decided to research turbo lag and build an anti lag system, similar to the proper rally ones;













(the new version is alot better and smaller than this but i had to dumb it down for uni...)


My dog "Garrett" helping me put the engine together;






Got ahold of the electric power folding mirrors, but i had to make a controller for it. I wanted it to properly interface with the alarm .etc





I added some puddle lights to the mirrors as well (just hyper bright 10mm white LEDs);



Crap but it shows in the dark lol




I made a computer to monitor, control and report warnings for all temperatures and pressures in the car. As the radiator is in the boot, fed by small NACA ducts in the sides, at low speeds there is no airflow. THis unit will run the radiator fans at increasing speeds as the car slows to a halt, to ensure the airflow is maintained. This is also done for oil and intercooler fans (intercooler due to anti lag).


Here is the most boring video ever..









I had some projector units knocking around from my wifes trike, so i decided to modify my headlights a little. THose familiar with the escort cosworths will see i quite like the quads with the innter lights removed lol











Made a battery tray for the boot;





and from underneath the car




Seam welded the engine bay, the rest is done but not pictured for some reason;






Cut the holes for the side exit exhausts...






Started making an S2000 cluster converter for all hondas to try and fund my build lol.








Made the fuel computer, this will determine the speed to run the twin aeromotive a1000s, to increase their lifespan and reduce noise;





It has built in fault finding and redundancy


In order to tie in the ALS in the most effective way, do away with the archaic thermo valve, and allow easy adjustment of idle, i made drive by wire for it- which also allowed me to give it cruise control lol

I used an audi throttle pedal for the system;













I also made a computer controlled rear wing. Which can raise and tilt automatically. this will vary the rear downforce and add massive amounts of drag during heavy braking- very much like the bugatti veyron wing.

























Not finished yet but here is some deveopment with the drive by wire actuator;










Some stuff on the rear wing actuator computer;














I decided to make my own cluster, using my original rev counter (looks tacky so ill be getting rid) and 2 LCD screens. This will show data on all systems of the car, fuel, cooling, anti lag, wing angles, 4wd .etc




Here is a little video of it testing. Just getting it to speak. The system i designed has voice warings, which will play through the stereo and alert me to anything wrong.















This is on the back burner for the moment as im busy with a few other things.. I can do this when im not doing anything else. Its all software writing so it needs focus..




Made my own steering wheel controls;








As i had to get rid of the Power steering pump to place the turbo, i obtained an MR2 electrohydraulic pump. My first system was manually controlled, but i designed a system to control it and put it in standby when necessary. To do it properly i made and intalled my own steering position sensor using a 10 turn pot and a toothed belt drive;




Finished and assembled the rear wing actuator system;






The mounts are currently at the chromer's (for protective coating- not bling lol)

fitted the actuator to the rear firewall.. Wanted to do it before i painted the actuator itself..









Latest engine pics- sorry ive missed a few boring stages;





the toothed wheel is the new timing system. Ive made a converter that allows hondata to use a more accurate 36/1 timing wheel, ive also made another controller that allows any standard (or hondata) ecu to run coil packs. Im using 4 audi 1.8t coil on plugs, which are awesome!


and recently the new and improved anti lag computer. Ive also added a speed limiter system for track days.



To bring the whole build upto date,

Here are some of the pics of testing the rear wing. Under manual control (no computer)







This is the view from the front, shows how much of a restriction the wing will cause when it is in airbrake mode;



I really never wanted to show my ugly mug on my build thread, but unfortunately there isnt any other way..







The latest job;







This is the new dash- to replace the old one- pictured above. I really hated how it came out.. Thanks to my dad for having my design laser cut..







and just for comparison (my original CAD drawing)



At the moment im just tidying a few thngs up, sorting out the custom dash upper panel to move the stereo up (7" screen) closer to the eyeline as the system im making relies on putting essential information on the cluster, but non-essential information on a "paged" display on the stereo..

Recently have managed to finish off a few jobs, but pictures speek a thousand words lol;

Finished the rear wing;



and a small video of me simulating the car speeding up and slowing.. The long pause at the end shows how the fans and PSU turn off after a period when no adjustments are being made..



I am building a computer and using the Skyline R32 ATTESA pump a rather extensive modification of my rear diff clutch actuator, ill be able to precisely control the bias of torque to the rear wheels, i can tie into the ABS sensors, the G sensor (for the rear wing) .etc to finely tune and develop it.. Here is a it of testing on the ATTESA unit;





I know an old civic isnt going to be everyones cup of tea, but I like it lol...

Absolutely incredible imagination and I'm so envious of your skills and knowledge. I'd be happy with a quarter of the engineering knowledge you seem to have!

Have bookmarked this one to see what happens next. Top diary mate, wish I could do the things you've done so far.

Not a fan of the rear wing or AWD I would have opted for RWD..... I do however admire your commitment and seemingly good technological understanding.


Will be awesome when finished though .....

Nice unique car! Some great ideas, but maybe a bit of scope for some weight loss ;-)

BTW, why don't you just use a std BOSCH electronic throttle body? Easy to buy, easy to drive(3A H bridge will do it fine, like an LMD18200 (http://www.national.com/pf/LM/LMD18200.html#Overview) and almost guarenteed reliability, which for ETC is a good thing!

Speaking from experience, i would also make sure you have an ESTOP switch placed so that front seat occupants can readily kill all the power to any "home built" ETC system..........

Wow that was rather positive- thanks very much chaps..

I can see why some wouldnt like the 4wd, to be honest its a weird one.. The handling of the car will be set up as a front wheel drive, as its only part time.. I can also understand the wing, its based on the wing which aeromotions in the states developed.. It should be interesting, especially if i can swap the aerofoil for a more aerodynamically specific one..

The ETC point is actually rather valid. Most of my items have redundancy built in, this however doesnt.. Ill incorporate an override switch onto the lower control console..
Ive been using OTS where possible, the only reason i havnt done it with this is that the throttle and inlet was a prototype from hypertune in OZ, but they never put it into production.. This method saved me having to disrupt the tidy inlet airflow.. It should be pretty bulletproof..

Thanks again chaps!

Any reason in particular for going that way? I always think I'd prefer to slide off the road backwards. biggrin

Not a chance mate, lol, i love the colour.. Its either that or skyline midnight purple 3..

I know what you mean about the layout, i would also prefer not to see the tree that killed me.. The main reason for the choice is the fact i spent quite alot of time on the engine before the awd idea.. Because the engine runs backwards, im limited by the choice of transmissions..

Day to day i work in military aircraft avionics..

That is incredible. I totally agree with you wanting it four wheel drive. What power will it be running?

I am having a mark one golf converted to awd. Only way to get traction if I wanted to run big power. Hats off to you, amazing build and innovative ideas.

Thanks mate..

Its a Honda B20, with a VTEC head.. Im running a GT3076r turbo with anti lag to keep the power delivery as nice as possible. The turbo being the limiting factor, i have seen similar specification engines running 580whp.. So thats my target..

580bhp....hence four wheel drive. I am putting a gtx3076 on mine.

yikes

Will be a bit mental when its done, have you upgraded the internals of the rear diff?? they fail on stock crv's so i would imagine it wont last long once yours is putting a lot more power through it.
