2.0 8v into mk2 1.8 8v

[marcus123]

tinman,

have a word with steve at c and r, he has got a mk216valve that he has bored out to 2.2litres.

which is the very maximum that ther 1.8 engine can go to, however that particular engine kicks out 197bhp, which is pretty unbelievable.

tinman, i thought ur 16v was unmodified?

Whooooaaaa there!!!

You have all got these ideas about a 2.0ltr conversion but havent got any body with a 2.0ltr conversion to comment.

"Enter stage left"  ME

I have a PB code digifant engined 8 valve that i have put a 2.0ltr in to.
The bottom end is a "tall block" code AGG as fitted in mk3 golfs and passats. This is 16mm taller than the PB block so things get a little close to the bonnet but it still fits. I have used the origanal PB head and have put a Kent cam in it, vernier pully and a reprogramable chip in the ecu. This was all set up on the rolling road and now pushes out 150 bhp. I beleive this is this the best way to get the most from a "tall block" conversion as the increasd stroke will sap a little acceleration because the engine has to rev harder but the longer stroke does giver greater torque in all of the rev range. So i would do the conversion but use all the trick bits that i have on mine and you wont regret the punchy acceleration it gives you.
Take a look at the TSR web site or C & R. they have 2.0ltr engines but use a combination of boreing and stroke to increase cappacity.

If you need any help you know where the forum is.

r u from notts mate?

how much for that conversion?

[jimbo]

nah I is based in the Lincoln area.... aiyh

The conversion totaled about ?1000 cos i did all but the rolling road work my self.
Two good things come of that: 1. the price is kept down. 2. I now know my engine inside out so any problems are easy to sort.

The reason the 2.0 16v in corrado/passat isn't quicker than the 1.8 16v in the golf is because the emissions equipment ie. cat and the poor inlet cam that goes with it.

Another question to answer,
isn't the 1.8 a bored out 1.6?
No, there is only one block, the crank and pistons are different on the 1.6 and 1.8, the block is the same, so all that is changed is the stroke. If you look at any 1.6 carb engined block it will have 1.8 stamped on it, that is why.

As far as i know the 9A block (2.0 16v) is bored as well as stroked over the KR (1.8 16v).
I will look it all up when i get the chance!

Also, its apparently easy to use the audi 2.0L 8v block in the golf, it is not a tall block so should fit no probs  

[marcus123]

hmmmmm, how much can you get one of those engines for vr6?

do you know what the power out put on one is?

[golfvr6]

Get an Audi block from a breakers.

Apparently they are good for 150bhp....

[marcus123]

hmmmmmmm thats interesting!

[redders]

no replacement for displacement.........or sumink like that
