The Datsun has the same stroke and bore as the Renault 5 Turbo,.. I am likely to go down the route of fitting an R5 Turbo to it,.. does that mean if I wang on Renault 5 GT Turbo ECU it should work okay?? I don't think its super programmable one!  Looks like this :  |

I thought R5 turbos used a wangng great carb? I know R5 turbo parts were used by Bristol stree motors to build Turbo Skodas.

Hmm apparently it is an Ingition module not a fuel supplying device...   |

I would use the A series distrubutor converted to electronic ignition with a high power coil and get it recurved to suit. The chances of the R5 ignition advance curve being exactly right is slim anyway.
I've already got the whole shebang for an A14 turbo just waiting for me to pull my finger out and do it. I pulled all the gear I have off a R11 a long time ago in anticipation of going down this road one day. I intend to get it all onto the A14 in my Sunny truck at some point.

Don't suppose you want to sell it all to me,.. cos I'm lazy  Actually 2 R5 turbos and a carb on ebay at the moment,.. furiously watching. Going to sort the ignition seperatly ,.. want to go MSD 6AL ,.. but I suspect thats going to be expensive, unless I can get a second hand one. |

yea, the r5 turbo uses a solex 32 DIS (iirc) which is a downdraft single carb. i have one in my garage at home which I'm not going to use now, make me an offer - as far as i know all the spindles are in good nick and the carb was ready to go after being re jetted. ( i will double check all this though)
as you say, thats the ignition coil pack you have pictured, if i where you i would look into somthing like mega jolt / mega spark. i have had a beif look at it and it looks pretty good, and is certainly cheap (about £100 for it and all the bits + a laptop to map it from.)

EDIS and Megajolt would be a better solution and programmable too ;D But your almost there for Megasquirt n spark by that point as well Do it once and do it right EFI with the throttle bodies, you can still turbo them later if you so desire ;D |

Yeah the ebay advert was confusing,.. labeled up as an ECU,.. and I thought it might be like the old Bosch jobbies rather than modern ECU... turns out its not an ECU ... well not as I understand it. Ratlookreliant : you got the whole thing? Turbo + carb? Or just carb? Either way I'm interested |

just a carb, the plan was to use it with a eaton m45 blower on a reliant engine, but decided the engine would probably last 5 mins with that lot on it! I'm keeping the blower for the super kitten! (eventual aim is TBs and a blower on the fiat engine!)
i also have some diagrams of the carb which i will send to you when I'm home - took me ages to find any 'free' information about them.

First Turbo, then ignition, then injection/tbs ... Ratlook: Carb would be ace,.. get me started... can get looking at manifold then whilst I track down a suitable turbo... |

Nick Ahh my engine came with the car so handily it was already fitted. Lets hope its as bullet proof as its reputation. I've not thought through the ignition yet,.. I'll probably go megajolt unless I can get and MSD unit at reasonable price, currently concentrating on cramming as much air into the engine as possible. Eventually I'll be using the Throttle bodies I got from Dom, think they are Yamaha..!? Dom?  (This is the kind of info it'll be useful to know I guess haha ) ... |

Yep Yamaha R6 ;D Could be persuaded to do you a deal on some R6 Carbs if you prefer Some cash and Carbs against the Throttle bodies |

That looks to me like a boost retard / vacuum advance ignition unit, this would be a great starting point depentant on price.
Megajolt is also meant to be very good, this is also a nice place to start as you can get this set up and running, and then move it all across to full megasquirt with out any modification. The megajolt unit will be snapped up by the mini turbo boys once your done with it aswell.
I def say go turbo, would be super cool! How close is you engine to the renault head wise?

uuuhhh..... ynot fit a silvia turbo engine and box and start there?? just a suggestion... si the reasons are 3 fold,.. 1) Space, nowhere to do an engine swap 2) Skill, I don't yet have the skills for it to be a smooth job 3) Its been done before |

The only bits that will connect between the ignition andthe ECU will be the PIP and SAW lines, mabe a power one too, so the majority of it will be stand alone with its own wireing. Once you have the full megasquirt you can move those wires to it and load up the map from megajolt, done!
R6 throttle bodies are quite bulky, GSXR ones are probably the most compact available.
