Q:
hi all
I am thinking about supercharging my car by using the following parts:
either a 1.8 8v g60 head or a 16v head
a 2l 8v t4(van) bottom end (or would the 2e bottom end be better)
an eaton m62 supercharger
2mm skimmed piston to lower the cr
electronic fuel injection controlled by mega squirt
cosworth intercooler(or have just seen the mk5 gti intercoolers i might use that)
if i use the g60 head then i would also use a kent gs4h camshaft or if i used the 16v just the twin exhaust cams.
can anyone see any problems with what i have just said or does anyone have any reccomendations?
and can i fit my 16v head to the 2l 8v t4 (van) bottom end
cheers

Hello mate,
Contact N7NDO on the Edition 38 forum (. He has similar spec to what you are building and can give you very good advice.
His Megasquirt and Loom were supplied by TIM-Sport who you can also find on that forum
A:
i tried contacting him before but got no reply back from him.

You will have to choose if you want a 16v or an 8v. I know the 2E tall block as beefier rods. I used them in my 16vT. I can show picutres of this if need be.
The twin exhaust cam trick was used by chaps in the US with PL/9A engines who dont have the KR engine or its long duration intake cam. This will not be needed on a KR complete head.
If you are going to fit a 16v head on a 8v short engine you will need to consider/calculate what compression this will end you as you will have a pent roof head and a piston with a big sink. For the 8v engine you can use the tried and tested stacked metal gasket method rather skimming the piston crowns. These gaskets are found on the the MK4 2.0 8v and MK3 ABF 16v and can be sourced from GSF. YOu will need a means of dialing in the cam timing as raising the head with an extra gasket/or even spacer advances the timing.
Good to see you are considering the DIY Megasquirt route. Quite a lot of us are running this EMS in our cars.
A:
hi mate cheers for the reply
was it only the rods you used out the 2e block?
I am really swaying towards a t4 2l aac bottom end with the g60 head and eaton m60 or 90 charger with just the stacked head gaskets now.Supposedly this combo with a g60 charger gives 240bhp and is only restricted with the amount of air a standard charger can blow, so the eaton m60 or 90 can blow a bit more.
Have you any idea what the differance would be between a charged 8v and 16v?
to be honest all i want is power,speed, acceleration just enough(well lots actually) to show a few new cars up!!(my next door neighbours new focus st3)
A:
hi Ryan
i too am going down this route
of course the characteristics from the 16v will enable the charger and general power to be alot more revvy as expected
i too have just purchased an M62 charger (sorry its M62 not M60 :) )
you will need one gasket to lower the compression
so far i am sourcing the other parts such as the FMIC and piping etc. Uprated oil cooler will be needed as well as engine temps will be alot higher and of course Megasquirt ECU
The M62 charger is a better choice than the G60, cheaper to maintain and the M62 contains its own oil feed and you dont have to put seperate piping in like you would with a G60
wanna work on this one together?

I only used the rods as they had more meat needed at my estimated power levels. The ABF jobs looked a bit scary down by the bearing shell arc. I had a problem with my crank and that was replaced with an 8v AGG unit rebalenced with flywheel and damper. Thats all the 8v bits I used.
A:
yeah tony we can have a look at this one together.
I have also been looking at the mk5 fmic but it does look a bit big and space could become a little tight in the front off my mk2. I was thinking off twin cosworth 4*4 intercoolers or the merc sprinter but again it is a bit on the large side.
I have an oil cooler and today i am going to order the sandwich plate and remote filter plate for the oil system which in turn gives me that extra bit room for the charger.
radiator wise i think i am going to go for a diesel rad with twin pug 205 diesel fans since the are the electric type without the huge motor at the back off them.
It is the m62 i was looking at and also the m90 but i have bought one yet.
I am also going to fit megasquirt but also a wasted spark ignition system so i can get rid off my dizzy.
cheers ryan

Why go through all of that when you can build it to trigger off your OEM hall sensor dizzy. Makes the installation cheaper and loom build straight forward as well. I built mine like this and it runs excellent. Of course there is no problem if you want to be different.
A:
the only reason i was going to do the ignition system is because i have everything lying about bar the trigger wheel.
I am still a bit unsure as how to do it but i am looking into it.

So I take it you have a MS ECU already configured as a wasted spark unit along with mutiple coils or coil packs sitting around then.
A:
i am about to order this week ms v3 and i have the ford edis4 ignition module, coilpack and vr sensor in my garage.
I was going this route because i have it most of it lying about and i thought it would overcome the problem of the advance and retard issue on the dizzy when the engine comes on boost.

Not a problem if you got a disi off a digifant if you are 8v, and any 16v distributer will work with MS no issues.
Should you decide to go the wasted spark route, you will no longer need the EDIS module with the V3 board. You will just need an aditional coil driver.

The dizzy is just a trigger and uses the same VW ignitor if you choose. Just as the EDIS 4 works with a crank sensor. As my fellow 'sqiurter AS-Tecnik said the OEM ignitors are not needed as you can configure the MS to haves its own coil drivers. For this application you will need two.
Advance an Retard are built into the spark map based on your engine hardware. In terms of hardware for spark you pretty much covered as you got many options.
A:
what do you mean by coil drivers?
so all i need is the coil pack and vr sensor?
that will do nicely thanks. I am going the to chop 8v and go from 16v to the g60 8v head if i can find one and put the kent gs4h cam in.

Coildriver is another name for ignitor. In megasquirt you can have these built into the unit..
You can use a VR sensor to trigger.
A:
cheers for that. I might have to give you a shout when i go to buy it or when i set it up so you can advice me what to go for.
I think i know what i need but it would be better if someone that has already got it could tell me what they have.
A:
I'm currently building a supercharged 2.0L 8v (big Bahn Brenner charger though ;-) so would be interested to know how you get on. I'm using just a standard mk2 GTi 1.8 8v head with a G60 manifold and throttle body.
A:
Now that i am going to run it on megasquirt do i still need a seperate module for the wideband lambda sensor or can megasquirt control that too?

You will need a wideband kit that will have an optional input to the MSnS-e EMS. Innovate,PLX AEM techedge ae the ones that come to mind. I have an Innovate LM-1 kit with a couple accesseries for portable work.
A:
with this setup will i need to run an additional injector for when it is boosting?
I will be using skyline injectors and have six so have two spare. What injectors are other people using?
A:
No....as long as the injectors are big enough the ecu will be able to control the fueling on boost without the need of an aditional injector (asusming its mapped properly of course )
You may run into problems using the skyline injectors as the wont clamp (with the small clips) into a vw fuel rail like a bosch type injector will. You will need to make a fuel rail and make sure its bolted securely down to the mainfold to guarantee a good seal.....TOYOTEC fellow squirter and also Skyline expert will be able to confirm this.
