FJ1500 Turbo EFI Katanaha Project, with a whiff of Nitrous...

[dixiethedog]

Wow,thats some impressive workmanship there. Now pass me my rotary table,indexing head and some big lumps of billet....I wish! Ive got the gear,but ive no idea.

[dixiethedog]

Thinking about it,with your bike (Tom) and FJ1289's bike,if I could have my fantasy FJ,it would be your turbo engine in FJ1289's frame. That would probably be an ultimate play toy for me. If I had to have my ultimate erm..Suzuki,your bike would be top of the list too. Although your engine in my efe would be cool.
Ive just arranged to sell an FJ12 that i have in storage,maybe i should keep hold of it?

Started to get the clutch cover together, Yantosh McYantosh turned up the Plexiglas clamp with O-ring, fits perfectly into the cover.



Like a glove.



Tomorrow I'll engrave the Glas, chop out the unnecessary bits from the inside of the cover and weld the rings into the cover.

love this build.
the clutch is amazing and why not show it off with a cover!!
i want one for mine!!
very impressed... keep up the good work!

Tom - might consider welding a spacer ring to make room for the lockup while you're at it. Much better solution than a cover spacer that requires two gaskets each time you go into the clutch ....

The only problem with that is the clutch hub doesn't run central to the circular cut-out on the cover, by about an inch. The Plexiglas cover has an O ring so it will perform like a quick access cover for clutch adjustment and set up. I shouldn't have to remove the whole cover until the first motor strip down.

I did consider this

Sticking it all together. Bolted to a piece of 20mm to prevent warpage.



Preheat.



Took a couple of goes to suss the heat required, old ally and all that.

[Havoc]

I need to tidy up the inside a bit.



Will engrave the Glas tomorrow if I get a minute at work.



Hope you like   

[Havoc]

Done.





Happy with that

Very cool, nice job!! Could be a job in that for you!!

Nice. If I had a nickel for every Yosh part I've used over the past 35 years........

Havoc,

Great project you have there, mate.  Your engineering and fabrication skills are outstanding.

There was only one photo that showed it, but the turbo cold side outlet pipes under and behind the motor up to the plenum?  Obviously no room for an intercooler.  But cooling the inlet charge is critical to increased horsepower and preventing detonation.  I have used water/methanol injection on a supercharged landspeed bike, and it really can be considered a 'chemical intercooler'.  Inlet temperatures lowered from 200+ degF to near 100 degF.  And the methanol is certainly an octane enhancement.  Side benefit is that your combustion chamber will be clean as a whistle.

You mention nitrous, but have not yet shown how you intend to plumb it up.  Wet or dry?  I like wet because it is more idiot proof.  Nitrous Express Piranha nozzles, drilled and tapped into the heads or inlet manifolds would be clean and simple.  Tee-off from your fuel pump to a low pressure regulator, add a few solenoids, nitrous bottle, a button, and Bob's Your Uncle.

Again, nice work.  I look forward to seeing more.

Enough nitrous does the same thing. I ran adapter plates for the nozzles but I do not think they are available anymore.

If you refer to the APE parts, you are correct, they're out of stock and not making more.  They were really nothing special though, it'd be quite easy to make your own, which will help you clear the starter if you use braided lines.

Cheers for the comments gents.

This first build will be relatively low power @ low boost. Just need to get it on the road for now, say 220-230bhp. Bunch of us have an aircooled turbo road trip planned for easter, any of us that doesn't run a 9 has to buy the tea. Will be using a blend of C16 and Super Unleaded to keep the cost down a little, also CR is around 8.5:1 so detonation shouldn't be an issue. The next incarnation after we got this silly bet out the way will be more of everything. A larger Ball Bearing turbo with Water/Meth injection. Our main man has plenty of experience with this having run Outlaw, ProMod etc. The Nitrous system is all that remains of my GSXR1340K from th video in the first post. I did run the APE spacer plates for the foggers on the Suzi but there is plenty of space on the underside of the inlets on the head to drill and tap. The system is a wet 'NOS', was running 32/34 Gas/Fuel with 100% C16 achieving about an extra 100bhp dependant on weather but will be starting with much smaller jets on the FJ motor. Both a boost controller and a progrssive Nitrous controller are waiting in the shed for 'phase 2'
