tsr pack A???

[chrissywood]

hi all i can get a pack A head off of a mate of mine for my mk3 2.0 16v are they any good??? And how much power am i looking at and wot other hidden costs am i looking at to fit it il get i fitted cheap as i work as a valeter for VW so a saturday job for a techy???

You are not going to need any other parts. Would be a direct swap, although fitting a more flowed head would be better with other parts changed at the same time. Might be good to fit new cams at the same time.

How many miles as it done since it was built?

[chrissywood]

it has done a few thousand but has just been rebuilt has got aftermarket cams in it already! anything els worth doing first or at the same time as fitting and will it need a remap when done??

What engine is it coming off?
KR or ABF?
Some cams will run in a KR that won't in an ABF as the long duration causes pulsing in the plenumn that the ECU can't adapt to....so you need to know which cams too?

As for gains from the head alone...on an otherwise stock engine...probably next to nothing.
The standard head will flow just fine up to 170-180 BHP so just giving it the capability to flow more will give you very little unless you can get more air in - but with cams fitted, other components optimised and the ECU properly re-mapped, you should be looking at around 20-25 BHP depending on the spec of your current engine, and the cam selection.

Costs, oil, filter, coolant, gaskets & head bolts - probably £150.
Fitting, say another £150, unless you do it yourself.
Vernier pulley - unless it has one (you may or may not need it...but won't know until you fit it and try) - maybe another £100
ECU re-map - £300ish maybe?

The rest of the engine will be fine at that sort of power...although porting the TB and modifying the airbox will help a bit when running with cams/head.

Depending on ther cams, you may be able to play with a set of internal cam verniers and optimise several other little bits to gice a cumalative gain...no reason why you couldn't see 190+ BHP if you spent enough time and effort...but much will depend on the spec of the head - A Pack is just a porting job, I believe.

You won't need a fancy exhaust, high flow cat or anything else at that sort of power.

the head with cams is costing me £300 and fitted for about £80 is it worth the money doing it?

[Mikester]

They are about £900 new, or 650ish with an exchange for an old head, without cams.

So providing its in good nic, i reckon its a good deal.

Yeah...go for it.

But you NEED to find out which cams are in it!
If they will run...great.
If not, use your current ABF cams.

[Paul86S2]

As stated before it will depend if its a kr or abf head.

ABF head will be no problem.

If its a kr head it will fit but the dia of the combustion chamber is slightly smaller than the bore. You will need a steel abf head gasket, and all other abf gaskets apart from the cam cover gasket. You will need an early abf or kr cam cover and cam cover gasket. You will also need a cam cover set of bolts.

Depending on how much the head has been skimmed you might need to shave down the dowels on the block slightly to allow the head to seat properly.

Ess three's info tells you about the possible gains.

TSR pack A heads can be done privately for about £400 and cams will cost you £300plus so the price looks good.

i keep getting toldto look at ess three's info but how do i do that?
