Looking for a turbo. Time to get serious

**WRT** · 16th January 2006, 09:19

Sounds like a good project to me - good luck with it all. Any chance you might be able to start up a tread on it and keep us posted on progress? Couple of piccies, bit of a write up, that sort of thing? Would be very interested to see how you get on, and how you overcome any problems you encounter.

Also be a handy reference for anyone following along a similar path.

Dude,just go to a wrecker who does import car stuff and you'll get one fairly cheap, see if you can score one off a 1200 starlet.or something.
Efi isn't easy to make or set up, it is the shiz but a lot of money and hassle...

I'd fuel inject it with a nice set of hayabuse throttle bodies (US$60 on ebay).ecu would be megasquirt 2 (www.megasquirt.info) (~US$300). I build one of those for my e30 bmw

without proper ECU engine is going to die either because of the knock OR melt. you need to adjust air/fuel mixture very precisely with turbo, other wise = big bang!. Aswell, I'm not too sure what compression ratio do you run, but for turbo you want sometihing along lines of 8:1 to 9.5:1 otherwise you wont be able to run any more than 2 psi of boost wihout knocking.

you engine block must be made of iron, alloy ones are going to strip head studs thread at first boost arrempt.

you need a way to control ignition, i.e. to retard it under boost.

seriously...

just EFI conversion with large ITB's (like hayabusa) would incerase your power, and you dont have the turbo lag and stuff... i would do that first anyways... if still not enought then turbo that.

large twin turbo legacy turbo would support nearly 300hp... too big for you and would spool too late.you should get something like 20% bigger than your intended HP.

bottom line: you wont make reliable turbo engine out of a bike engine wihout serious internal work. on your place i would go EFI, port a head maybe, still not enough ? nitrous. cheapest option would be to sell your bike and buy faster. period.

I have been involved in building several 'high performance' very custom vehicles and i have an idea how much it costs and what to expect. you can have only two of these three - cheap, power, reliability)

Bollocks.

My answer to every power option.
DROP A ROTARY IN IT. 12A 6Port should be fine or a 10APP. Very progressive power curve and a very light engine (for a 1000cc).

Yes please start a thread, I for one would be very interested in how you go. Would be keen to do it to mine, when time allows.

more power . . . more power

How is it your rep is so high, when your obviously a reciever of swollen goods?

I dont need a k6 thou to make you look like an old woman, on the road or the track.

Thanks for pointing out to all the readers that my bike is worth fuck all, makes them see that even without a $15k ZX636 you can still be fairly rapid.

OK, here goes, CRAP! The big turbo off a Legacy, is still relitively small, the turbo off a Starlet is friggin tiny.
Reason for the bigger one is that a bike revs an extra 5000rpm on the starlet, which means that it would stop making extra power before i get to the business end of the tacho.
The alloy block, barrels, and head will be fine to run the 6 or 7 psi boost I desire. I will be fitting an alluminium base gasket to lower the compression, so no worries there.
Timing is a bit trickier, but a simple boost switch is all that is required to overcome the issue, shit, if i want i can run a linkage from the waste gate actuator to the timing pick up plate if I want to get super simple about it. Or, water inject it and flag backing the timing off at all.
This is not going to be a 300bhp dragster, I'll be completely honest, the goal is to be able to hoist the front wheel, off the throtle at 120kmh.

Yea on ya Drew, keep it RAT though mate, thing will have no class otherwise. I got the original TL fairings painted black and put back on, shit the thing looks almost respectable now, it's sad really.
I know exactly what ya after ion regards to power and yeah you could buy a faster bike but that would take the fun out of it, and with any turbo bike no matter how fast it is, boost is addictive.

**Drew** · 22nd January 2006, 14:59

...the fairings are just about ready to go back on now.

I do prefer to ride a tidy bike, but at the end of the day, most the people I ride with only see the tail light and exhaust. Eh deano

**aff-man** · 22nd January 2006, 15:02

sounds like a cracker of a project. Keep us posted with pics if possible please..

Awesome stuff.

Pictures will be posted. As soon as I get a turbo, the head and barrels will come off and the process begins. Photos will begin with a before shot and some dismanteling shots

Where the f**k did you dredge up this shite?????

Nearly everything in this is rubbish!!!!
The megasquirt idea's not bad though (I'd forgotten about those...) but I've still yet to hear of one running properly on a bike.

Cheers for that bro. I tried to reply to the comments tactfully, but you put it moocho gooderer.

I'll take this opertunity to re-establish the call. Please can people ask around they cager buddies for a turbo. Dont worry about what it's off. Just post what you have found, and we'll go from there. Cheers to all. I'll be visiting some wreakers this week, and hopefully make a start. My clutch has begun to give up, (possibly due to wheelies, but you cant prove that!) He he he.
So I will be getting my FJ1200 going and taking the FIZZER to bits before I get the turbo anyway.

I'm hoping you're taking the piss there Drew, else I suspect someone else is worried about their own swollen goods.
