Megajolt or Turbo Dizzy,
Turbo Mini Forums

I haven't bought either yet so I'm weighing up which will suit me best.

Budgets are running thin after just waving goodbye to my shell as it's headed to the bodyshop.

Do I really need Megajolt? would a turbo dizzy from a mg metro suffice? if I was to get the dizzy it means I could also spare some money to upgrade my cam to a mg metro cam. So either Megajolt or Mg metro turbo dizzy & Mg metro cam.

Basic specs are..

12g295 head.
Gen Challenge race carb.
T2 turbo.
TM Plenum.
Mirage Manifold.

I have megajolt its brilliant worth every penny..Alan

But am I going to benefit hugely from it? I'm only running a timid 998cc! nothing serious!

i would get the good cam first. use the dizzy

then save up for megajolt later..

and yes mega jolt all the way!! no cold start problems stays in tune no water issues, runs closer to a modern car.

you can properly tune your car for more power.

As Nick says, you can always add the MJ later whereas changing a cam is a bit more laborious.

As above but might be worth investing in the trigger wheel/bracket/sensor now as they will be a lot easier to fit with the engine out. Then save the expensive bit until later.

Schrödinger's cat - so which one am I ???

Why not do it right in the first place? A turbo dizzy will probably work. But it'll never be quite right. You'll benifit in all areas with megajolt. It'll start right, run right use less fuel etc

How long is it going to take you to put the car back together after being sprayed? Longer than it'll take you to save up for megajolt I recon!

You'll only regret not buying megajolt, plus you can get a bigger intercooler in without a dizzy - and that means more boost!!!

It'll only take a month or two to reassble it all (as if, things will go wrong and it'll take longer)

The main factor is that I'm at uni and my funds are limited and running dry!

I think for now instead of buying Mj I will use that money to buy a new cam & a turbo dizzy. As long as it runs and runs smoothly I'm happy! If I had all the money I'd happily splash out on it all!

The MJ will make a massve differance. I wouldn't even entertain a dizzy now.

It will work and it will be safe though, but unless you have one or can borrow one I wouldn't spend money on one.

And he got good results on the rollers!

Yep, flat out there is not much advantage having MJ. It is every other throttle opening that it becomes better. i.e 90%+ of the time driving. The MJ allows you to max out the advance when on light boost or no boost, improving MPG and drivability.

A man without a project is like a like a woman without a shopping list.

I have a mk1 metro turbo ignition setup if your intereseted, bought it but never used it because I havent got the engine back together - new cap and rotor srm included, silicon leads and brand new spark plugs will send piccies if your interested
