Hey Guys..bad weather out there today so i thought its time to tell ya all about my project.
This has been a long term project and still has a bit to go.
I have a 1972 1200 coupe which was purchased about 8 years and imediately stripped.Every nut and bolt was removed as well as the sill panels and all glass. We have stripped the shell to bare metal and replaced the sills and all rust with new steel.the front wheel arch (floor section) was un-tacked and about an inch removed ,then re-welded back to give more clearance for biggger wheels. The trans tunnel was sectioned and approx 100 mm added down the middle then rewelded to allow for the bigger bellhousing and box.I have modified the firwall and strengthened it to accept the clutch master cyl and brake setup.I used a 120y power booster with an adaptor to fit the 180sx brake master cyl. I have addapted with flexi fittings on the top of master cyl (brake) and run off to remote resevoir.The clutch resevoir can be accesed between the intake runners.The crossmember has been strengtened and modified to suit the fj20 and we ended up using ford escort mounts. its a tight fit with still bonnet clearance and enough room to fit radiator and electric fan(mounted behind grille)The motor at this stage has been left alone with just the chain tenoiner modified(fj20 bit noisy in that department) and the turbo o/hauled. the dizzy proved a bit of a headache. I ended up with a e15 points dizzy to start of with which we had to machine and jin around with to get it to fit and work then after all that stress we found a e15 electronic one and went thru the whole process again.the throttlebody was modified and fitted with lpg venturi ring and century barrel valve, the converter was also modified to deliver more supply (dedicated lpg) . WE made up a new stainless pipe to run from turbo to throttlebody and fitted a blow of valve (my son made me do it)..the lpg cylinder was mounte between the wheel arches and the valve box faces towards the front of car (access is gained from inside car by dropping rear seat back down..We also made an entire rear parcel shelf out of steel tubing and mdf wood to fit the speakers..Ended up wit 2x12" woofers,6"mid woofers and 25mm dome tweeters mounted there.The rear side panels were reniforced ant fitted with 5"midrange and 8"woofers. the doors are fitted wit a 6' split system and the sun vissors hav 2 tweeters in each and re-apholstered. In front of the Gsa cylinder and mounted to the back of rear seat are the amps and electric crossover unit. 6 amplifiers of differing sizes and brands (all the amps ive accumulated over the years) are used with a total output of 2400 watts.and with the covers on and the seat up you would never know . The dash has been re apholstered with Gosh leather and the Gauge area modified with the light and wiper switch side by side with boost gauge under them and oil and temp on right side. the deck and parametric graphic with sub control in the middle,ans the glovebox modified wit the 8 rocker switches to turn fings on and off,and 3 digital multimeters, 1 for the two batteries ( mounted in battery boxes in the boot) and the other two for temp monotoring(switched for two probes on each meter) under them is a digital lambda meter and greddy turbo timer( again with glove box lid atached by velcro you cant see none of this) plenty more to tell and plenty of pics to post( waiting for an album) to be continued.....

Cool, interesting story.

I'm battling with the clearance issues with tyres at the moment. It's a really big pain in the ass.

8 years is a long time. I'm impressed that you have not lost interest.

Thanxs Dattodude...yep its been a long term project and now my 14 yr old son is on the job with me,so theres a better chance of getting it finished. We had the coupe on the road 8 yrs ago with the fj20 running petrol and 4.11 diff ratio and the memory of the fun and awsome power has stuck in my head..with 11 lbs boost it ran 12.3@118 mph and went 0-100 kmh in 4.3 secs..Was a real struggle to get it off the line with 4.11 so we have gone with a 3.43 to tame it down a bit and with the lpg system we hope to be able to run between 20-30 lbs boost. we have done this with a ej20 turbo subi brumby and sr20 hilux ute,so hoping mine will do the same...cant wait and i must say its by reading all of you guys posta and stories that has got me motivated again... just dont feel like working on mine when ive worked on cars all day,the old mechanics car dillema i guess
