2.0 Mi16 Running R1 Carbs?

[Guest purpletoddy]

Hello people,

Having searched for ages on different topics i have decided to change the engine in my 1.9 gti due to a big crack in the back of the block!!!!!.

 

I have just taken delivery of a 2.0 mi16 (pros and cons all concidered thanks to many topics/post's). I had one look at the wiring loom and about fell over !!!

 

I have decided to junk the inlet manifold and injection in favour of a set of r1 bike carbs. Which have now been bought and are gettin delivered as I write this post. I was going to fabricate my own inlet manifold but after viewing a few topics decided to leave it to the pro's (Bogg Brothers).

 

My question is: How the hell do I get all this too work?????? 1.9 loom with dizzy adaptorand keep mi16 coil packs???? or megasquirt etc?? I have looked at a few posts and used the search and found a few ideas whats the general opinion what works best??? money is an issue but willbe able to stretch a little for a better set up motor.

 

The car will be mainly used for local journeys and track days etc at knockhill, I have decided to use the 1.9 gti box with the 1.6 final drive after calculating and viewing www.mdracing.co.uk/gear_ratios1.xls

 

Any suggestions will be greatly appreciated

You have a few options the way I see it...

 

1). Retain the Mi16 ECU and allow that to distribute the sparks and just cut off anything related solely to injection.

2). Use a dizzy adaptor, grab a dizzy, coil and associated bits from a Gti and use that. Maybe get the advance curve altered for your engine.

3). Use a KMS/Emerald/Others ignition only ECU.

4). Use a MegasJolt, bought or built yourself (one on eBay at the moment I think)

 

I keep changing my mind on my new engine spec... But seeing as I have a rebuilt Mi16, I might just keep that and modify the twin Weber manifold to accept the Honda Blackbird carbs I have in my wardrobe and then buy a KMS ignition only ECU from Matt at QEP as they seem excellent value for money.

 

But, if I upgrade or go straight to TB's then I may just get the full ECU first and just let it control the sparks with the carbs, then, when I go to TB's, use the injection facilities. This then makes it a futureproof upgrade.

 

I don't think there is any doubt that the best way to go is a full ECU... The next best way to go would be the standalone ignition ECU, then the dizzy last... But it's up to you and your budget.

 

There should be plenty of threads about ECU's in the aftermarket management section and there are no doubt a few people running Mi's on dizzy adaptors, although they are getting rarer. Give Matt at QEP a call and see what he would recommend, they are the forum sponsors and know what they are talking about!!

 

Welcome to the forum by the way!

Cheers for the quick reply mate,

 

Will the blackbird carbs run ok on the webber inlet manifold is the distance between exit from carb to inlet not critical???? seen a few posts on this last night and people were experiencing power fiqure problems down to this (I think im right on that one anyway).

 

Im new to this forum as just got the pug which i love by the way apart from when i accelerate it wants to change lanes on its own!!!!! its in bits at the minute as im rebuilding all suspension (recon rear beamstill to get SSP are the boys??) new wishbones droplinks track rods etc.

 

I think that ill not go down the dizzy route prefer to go with the technology!!! ha ha and im running carbs??? oh the irony.

 

I think ill have to do a bit more reserch on this through the forum and QEP as you mentioned and get some fiqures together before i make a decision. I would love tb's like gsxr1000 grr!!! that would sound lovely, i just love bike stuff and bikes in general....and of course my 205!!!!

I have no reason to suspect that the carbs won't work with the Weber manifold, the total induction length isn't going to be that much shorter than it would have been if I was running TB's or Webers, so I will find out I guess... Means I don't have to get a manifold purpose made, so I can remove that expense! I'm not convinced that everyone with problems are having them due to induction length, no one is going to be *that* far from a reasonable length, so they should still run fine unless there is another problem!

 

Go with the standalone ECU and then look at TB's later on... It has to be the way forward!

[Guest purpletoddy]

ive actually been looking at that today!!!! My mate is after my carbs so I may sell them and get some gsxr 750 or zx10 tb's grrrr!!!!

 

Doyou know of a website as follows: www.mtechautomotive.co.uk found it today and the guy who runs it was vey helpfull.......his ecu that would do what im after with the tb's cost £265 inc vat and its designed for pug's. Have you any dealings with him??? you seen to know everyone else!!!! haha

 

Total cost them would be approx:

 

Manifold Bogg Bro £150

Gsxr 750 tb's £150

mtech ecu etc £265

plus other expenses obviously but still quite cheap compared with jenvy's etc

 

What injectors would i have to use????

[Dom9 2]

Nope, don't know of those guys but... When it says it is based on the MegaSquirt, my best guess would be that it actually is a MegaSquirt and they build the loom the right length depending on what application it's for and then sell it as tailormade...

 

Nothing wrong with that but it seems like a lot to pay for an MS and I presume you still need to buy the Ford EDIS kit to get it to do the ignition, which will push it over £300 and getting towards the sort of money KMS want.

 

Alternatively, people build and sell MS units on eBay for much less, or you could make your own!

 

You can use Mi16 injectors upto around 180bhp... Otherwise you are getting into Cosworth, Rover turbo and other injectors... Easily sourced on eBay or on here, think there are a few threads to do with injector sizing if you do a search!

 

If you read Dreamweavers hugely long thread in the general section of this board, you will see he has used bike bodies and made his own manifold... All interesting stuff!

[Guest purpletoddy]

with reference to the ford stuff it states that you dont need that. Its designed to use the mi16 coil packs etc, which would save a lot of hassle,ill have a look at that thread you mentioned though, cheers again peter

[Dom9 2]

Maybe... I just skimmed it... But the EDIS isn't just coil packs, it requires other bits and pieces, it's actually a separate control module... Do some research and see what suits you best!

 

If that place charges a bit more but gives you good support, then maybe it's worth going with them!
