are these deep knocks after a while or like immediately?  all that work and money and then it knocks 

was it a big turbo?

These were converted presumably from new. So both had covered some miles.  Can't remember the specifics, but don't recall them suffering much lag, implying small turbos.

Interesting. So pretty much we can say that these engines are no good for turbo charging!

In my opinion,get a nissan skyline engine,gearbox,loom ecu etc,fit that instead of turboing the mig.

Here do...

How closely related is the C20LET to the X/Z20/22 unit?

A cheap, early facelift 2.0 manual would be a good project base, rather than messing with Eeyore... that way, if it goes horribly wrong then you still have your nice car

Easiest way to get a bit more oomph into your nice car is to drop a 3.0 lump in

I should have prefaced by saying I wouldn't touch Eeyore! I'd buy another one; funds permitting of course. That way I don't wreck my daily driver and the best Omega ever  and basically do what gixers doing with his V8.

As for dropping the 3.0l in.... already on it

Thanks for all your input dudes.

Knowing the very basics of turbos..... would a small turbo not compliment the omega.... turbo for initial acceleration that is lacking cos of the weight of the beasts?

So I suppose the huge issue with this would be the making of the manifolds?

Webby, omega can be converted to turbo.. but many parts would need to be re-located,  some parts machined , welded , new parts added etc etc..  but for a car that size and weight , you will need 300-350 hp to say its fast.. and even in that condition, with 2 rear tyres spinning you will loose most of your power ..  and I doubt ar35 can handle this much power for a reasonable time.. you will need other autoboxes.. and the cost will multiply within short period..

Damn , beat me to it

Cem, I think youre right re the boxes. assuming it is an auto, that chap in the gallery shredded around 6 boxes in short succession

buy this and you are done.. trust me it would be cheaper .. only service costs and fuel££££

Obviously, as soon as you sit in it, you have to have a lobotomy. Hopefully only temporarily until you get out...

From old posts it's fairly clear the bottom end can't cope too well with forced induction. It's the reason why one of the v8 conversions came into existence, as the original 2.6 (?) was fitted with a supercharger and too much boost. It destroyed the bottom end, prompting a... More "sensible" route to more power.

I'm wondering if I'll ever really get started on the problems with the mv8, given time constraints.

how much boost ?

I must admit when you sit in a "relatively" fast car ,  most people (including me) have some transformation   




clit is now 6 secs 0-100 ,so I'm still in the phase of learning how to drive slow

Don't know. A nats cock more than atmospheric iirc. Thoretical max of 250hp rings a bell. Whatever that equates to. So not really worth bothering with. There's been several threads since it's all on here somewhere.

Basickly, don't force feed the v6, it WILL shit itself! It just will.

Iirc it was accepted naturally aspirated was the way to go, with tube manifolds instead of cast collectors on the oe ones, and accept the engine will flat at low rpm.
...from memory.

But you know what my memory is like.

if we assume a theoritical value of 250 hp for a 2.6, it must be around 6 psi.. not too much boost.. but cant predict the original state of engine before turbo
