I run a megasquirt setup in my kitcar, using honda blackbird throttle bodies on a vauxhall red top. Its all do able but there's a lot of messing involved. If you want to do it read the mega manual etc. If it all makes sense then crack on. If not prepare to waste a year of your life going cross eyed looking at fuel maps etc. Like anything the temptation is to make it more complex than it needs to be. I had it all running on standard manifold + dizzy etc so decided I needed TB's and DIS then wideband lamda and so on.
A lot depends on what engine you've got and if it has been done before it will help because someone else will have made sense of it.
You may also find its not much cheeper than buying off the shelf kit.
So what you thinking of building then?

My mate has a 2.0 vauxhall engined mini running it with a pair of Fi webers bodies. Best place for advice is probably on the VZi forum. Loads of people over there are running it, i've been tempted myself, would look into the canems set up, weber Fi and megaspark.

As above though it will depend on what engine your thinking of.

looking to make a b230 (volvo) with a ulta simple and relable fuel injection system. the early ones used a botch k jet system which is bullet proof system. but theses are getting quite hard to find, the later ones used a compleate electronic ecu and a quite complex, the k jet may be the better system for me, i want, simple and strong. just at the reashurch stage at the moment. drawn to the volvo unit for is torque, strenth and reliabilty.

Syncrosimon and I have talked about the megasquirt as a replacement for the 2.1 dj/mv system when it has worn out and decent replacements are no longer available. I think the majority of the info we found was obtained from thesamba.com

tencentlife has posted on here and he is very knowledgeable it would appear. If he doesn't come along try a pm?

I'd be interested to know of anything you discover...

K jet rocks.. but hard to find ggod ones now.. My A100 2.2 is brill..

Mega squirt etc, needs thinking about and understanding.. then setting up properly.. I've been looking at using mega/micro squirt for one of my bigger wbx project engines.. but funds are too tight at the mo...

i will start doing my digging around for some more info. looking at somthing simple i think that it is gona be a a case of evolution not revolution though. i will keep you all posted.

Wat models do they come in as I may come accross one at work....

[Damien]

What model and year are they fitted to?

hi si if you asking what modle of volvo it the engine would be in a 240(carded and injected) ,740 and 940 the 940 (in the uk) the 940 is the most refined being the last modle to have this engine.basicly all the rear wheel drive cars up to about 1997 when volvo moved to front wheel drive. all of the b seires engines can trace the routes back to the 1960's from the first 1.8 design and evolved from there. an ideal engine would be a b230fx for a late 940 the most powerfull non turbo 132bhp, vai a high lift cam (buy volvo standards)and a re worked head but this relies on haveing a very complex injection ssystem. and i would get confused i think.

if the right car came up at the right price i would like to but it and drive it for a while before choping it up.
there a guy that i know in norway that will make/program a volvo ecu for me to keep things as simple as possible. basicly he will provide an ecu with the releven wiring that i can effectivle just plug in the the relevent sencors in the engine and away i go for a price though. i just have to let him know exactly what engine i have. or makeing a system just working out what is the best option for me

update on the engines,

just got word from sweden that there is eneough space in a doka and sika for any of the of the b series engines including the turbo units, which makes sence be but the intercooler (normaly the same size as a rad) is not practical to use. which could male things rather intresting . the exaust system would work like on an aaz fromthe pics that have been emailed to me. i dont know how to move the pics from my email to show you on this forum.

I also run Megasquirt in both my kit cars (westfield & Vindicator) and can confirm its a lot of fecking around.

Its great when you have some sort of Throttle position sensor installed on carbs or equivalent as standard. If you're trying to make it run using a toothed wheel on the crank to monitor throttle position it will be unreliable and all engine MAPS will be a bit off (NOT FUN AT ALL). If you're still going down the megasquirt route, get ZXR6 carbs (with Throttle position sensor built in) and make an inlet manifold to fit. Would recommend "Bogg Bros" (http://www.boggbros.co.uk/fabrication.html" onclick="window.open(this.href);return false;).

Let me know when/if you get that far and I can maybe do some custom engine maps for your ride as I have access to a rolling road, etc.

After its fitted you'll spend the next 6 months worth of weekends trying to jet the damn thing properly!!!.....(Buy A LOT of different size pilot (slow jet) screws...you'll need them).

The guy who used to be next door to me does scrappy-esque car collections and usually bung his mate all the volvo's for banger racing, i'll ask him to let me know what he gets in for you.
