2.0 9a????

Is that the right engine If I want to do a conversion on my 1.8???

If so Is there a topic or any where I can get some info a=on how easy etc it is to do!!


Dave

 

you can also use the audi 6a and the MK III abf (although the abf is taller)

 

Oh didnt know that, so what the best engine to use then?????


Dave

 

from the research i have done, it seems the 9a is definetly the best bet, as the 6a has different manifolds and the abf will be more expensive and will require minor mods to the bonnet. the only thing against it is you are more likely to get a lower milage abf than a 9a but if its out of the car, you can always re con it!?

 

Well thats what I though, I was told it is a srtraight bolt on job???


Dave

 

for the 9a it is, although you'll want to swap the cams across and probably the flywheel as well.

 

why the cams??? Are they a beeter profile??

 

The inlet cam on the 9A is a softer profile than the KR because the 9A has a cat. The KR also has a bigger bore inlet manifold.

 

Right so its not just a case of bolting the 9a bottom end to my 16v head??


Dave

 

it is much easier to keep the head on block and just swap the cams.

 

Oh and just drop the whole engine in in one go.

Write I can get a passat 2.0 with 87k on for 450 notes is it worth my buying the whole car or looking for an engine own its own????


Dave

 

i take it that' a 2.0 16v?

i'd buy the whole car. you'll have the ke-jet injection to hand as well then wich may be worth using as the 9a is higher compression than the kr and should benefit from the knock sensors

 

Yes it is the whole car, did they do a 8v 2.0 and a 16v as I dont know if it is a 16V. As i thought i only neeeded the bottom end.

Right if im using the whole engine, the knock sensor etc Surley i will need to use the loom as well?? As this is somthing that I may not do myself, If its just a straight swap i would diy but if it requires cahnging of loom im not to keen!

dave

Thanks for ur help so far Gti

 

the 8v bottom end will not fit a 16v head. you need the 9A bottom end, which is from the 2.0 16v passat or corrado.

as noted before, the conversion is also possible with a 6A but it requires a bit more spanner work. i have a 6A in my Mk1.

swapping the loom is your choice, depending on which injection system you use. you can keep the k-jet you already have or swap to the ke-jet from the passat if you want to. sounds like you'd want to keep it simple and stick with the k-jet. this is the most common choice.

 

Yeah I would want to keep it simple. I will source a 9a engine etc and give that a rebuild before. So I think I will just keep the original loom and just drop the 9a lump in, get me some fast road cams and mabey a new head then off we go. lol Just like that.

lol!

given that the 9A and KR heads are interchangeable you could keep the KR head from the 1.8, have it gas flowed and rebuild it - then swap onto the 9A block at a later date. that is what i'm doing with mine.

 

Aha, or if Im not in a rush just send it of to be flowed, bigger valves etc then just stick on the bottome end which I would alreeady have installed in the car..he he....
As Im sure doing the head that way is alot cheaper than buying one...!
Whos doing you head??

Regards

Dave

 

that's exactly what i meant!

i'm doing as much as i can myself (stripping and rebuilding), but the gas flowing and other machine work i'll get done somewhere local to me.
it won't be for a while yet though as i'm trying to reduce the size of the golf shaped hole in my wallet!

 

lol...Well I should be able to get the engine cheapo as I know the local scrappy yard son v well and I know the local vw brakers.

Oh Oh Just thought what about gearbox's??? Can I use my 1.8 one or are they all the same????


Dave

 

do make sure its a 16v lump, not 8v!!

the 1.8 'box is fine.
