JX-1Y-SB advice please!

Post by Chilla »

Hi Yall

Here's the crack

just bought a 1.6td crewcab which had a head gasket gone and was laid up for about 18 mths. The engine appears seized as clicks on the starter and I cant get any movement from the pulleys

I have 1 running 1.6 SB from a 92 passat (80hp) has about 183k on the clock but runs sweet and 1 running 1Y. Both these engines are out the vehicles

Any ideas as to which would be the best approach to get the vehicle going asap
thanks in advance

Both engines will invove about the same to physically install, the SB has the additional complication of the intercooler to install which is simple enough in principle but will involve getting sufficient bits of duct and hose, and finding somewhere to place the heat exchanger. It may also have a water-cooled turbo, so unless you can re-use the standard one of the JX, there's the additional work of plumbing it in. TBH if you just want the van on the road ASAP, and aren't worried about getting the most power, fit the 1Y.

Fit the 1Y and turbo it.

It will be painfully slow but you could always add the turbo stuff at a later date.

at 65 odd hp I'm suprised the 1Y is much slower than the 70hp JX.....just have to get used to the pain I suppose.

Anyone care to guess what a turbo will do for the 1Y as far as power improvement goes....10hp maybe?

Its torque where the real difference lies.

A 1Y with turbo is basically an AAZ with weaker pistons (but nothing to worry about) which puts out 75bhp but much better torque output over a bigger range, can easilly get another 10 bhp by turning 1 screw.

There are things to go wrong and do but overall much better than the 1.6's

Every pump hass one of them screws. Go for it, only problem will be oil return pipe from turbo will not be long enough. Do not forget spigot bearing the 1Y won't have one.

Baxter also stocks longer turbo oil return lines, see:

Cheers Guys !

Bit of concern when reading the link

http://www.brick-yard.co.uk/VehicleSpec ... ds/aaz.htm

Could I get some advice on the following from the link

1. Whats the windage tray ?

2. Use AAZ injection pump, modify throttle linkage - Should I use 1Y or JX injection pump ?

3. Use AAZ inlet manifold, JX and AAZ ports are different shapes - Do I need an AAZ inlet manifold ?

thanks in advance!

1. Its to do with sump gasket, its not the anser to t25 oil problems so ignore.

2. AAZ or JX pump they are both "pooh", linkage will not need not need changing in a doka.

3. Yes you need an AAZ inlet maifold but need JX exhaust manifold.

Cheers for the info so far

just been out having a look at the 1y prior to taking it apart. Noticed the flywheel (which was detached from the engine when I picked it up) looks nothing like the jx (or sb) flywheel. A pressure plate is attached directly to the crankshaft. I dont have any history of where the engine came from (bought with doka) guessing it could have been out of an auto....any ideas ?

Also, put a breaker bar on the 19mm bolt on the front crankshaft pulley and pulled very very hard... didnt budge any ideas what torque these are done to? .....go on tell me its left hand thread.
cheers
