TDI arp head studs?

[appy86]

Hi guys
im looking for ARP head studs for my PD160 engine
currently the car is running on 3 bar boost if i drive normal the water and temp is fine but when i start to use the force
water starts to boil out of the bottle

i replaced the thermostat, water bottle, water temp sensor pipe and flashed the whole system.
so im thinking my head gasket is to blame.

want to fit arp studs to keep the boost in

Darkside is the easiest I believe

Darkside is the easiest I believe

Ive always wondered if it actually is? Is it worth it to pay the extra or is it just that difficult to source these parts in ZA?

Yes they are worth it on a lot of parts. When I bought my diff they were at the time the cheapest in UK that I could find and it was still cheaper once shipped and duties paid. I will say not every part is “cheaper” but like I already said there is a lot.

so n update on the ARP studs

i had to buy from darkside, cost alot but i could not find anyone in S.A to get them here.

while the head is off i sent it in for full recon and then do swirled 3 angle back cut valves with port and polish.

prev power was 281 hp and 484nm (no nos)
hoping i can go over 300 mark once i refit everything.

ill have my tuner just log the car to see if he can do some fine tuning on the file

So what was the cause of your issues?

but why does the torque seem low for a modded diesel? they usually 500nm+

[panic-mechanic]

Probably big turbo so peak power much higehr in the rpm band, which means torque is down but hp is up.

True about the Big turbo but torque is probably low due to injectors not possible to flow enough fuel in the high rpm.

Hopefully you can up the boost more now.

[appy86]

stock head bolts lift under 3 Bar boost.
when you do big turbo you loose torque.

still running stock injectors and not going to buy tips. its not a race car
hopefully ill have my head back from porting and mods.

once the head is back on ill have if fine tuned and later go down from 63 mm to 57 mm boost pipes
think my boost pipes are to big.

[Boosted_GP]

3bar boost and less than 500nm of torque?

How are you calculating your boost? What size turbo do you have? Why do you want to reduce your boost piping size?

Hi , i am glad that you are sorted with the arp head bolts i am sure this will help with that high boost.

"when you do big turbo you loose torque"

Btw this statement is not entirely true , Yes small turbos could make make a lot of torque at low rpm due to the the quick spool up thus the rpm is still relatively low and injectors can inject more fuel in low rpm than high rpm

Big turbos takes longer to spool and the power curve changes , your kw increases but torque dies out a bit , due to the injectors not able to injecting enough fuel per duration's in high rpm .

If you had bigger injectors that will be able to supply fuel right trough the rev range big turbo will also make 550+ nm torque .

No need to change boost pipes according to me , rather spend that money on upgrading something els.

[appy86]

Big turbos can do over 500nm true BUT the problem with tdi's is that we run out off RPM
my turbo gives me full boost @4000 leaving me with about 1750 rpm

bigger injectors will help all the way in the power curve but spending another 18k on injectors is not worth if for me.
i dont do drags or racing. my aim is just a stupid fast diesel daily trekker.

really cant upgrade anything els on the car other then NOS
It will give me a lot of torque and spool turbo faster but its cheap power.

im going to change the boost pipe that gos from turbo to intercooler first seeing that that is the long on.
if i can get my boost from turbo to cylinder faster that will increase the torque too

if it works ill then do the over pipe from cooler to intake to see if that does something.

[M@rk]

What size turbo do you have ?

GT2269

PSI gauge and the turbo size is gt2269
need to go smaller to get the Boost(air) from the turbo to cylinders faster.
big pipes or to long boost pipe can make the car lag more. the same with to big a intercooler.

remember all piping and cooler needs to fill up before it gos to the cylinder.
big turbos is all about how fast you can make it spool.

[Ashveer03]

Lol not again.

GT2269? U can have ur boost pipe straight out the turbo into the intake and u would still have lag.

If u want response for a daily driver, get a smaller turbo.

The gtb would help a bit. You don’t meantion how the turbo is fixed to the cylinder head. Did you, cut and weld it to a stock mani or cut and flange it? Did you fabricate a log mani or make a tubular one? Plus there is the fact of using fuel to help spool. There is also the fact that if your physical actuator setting isn’t spot on then that would have a negative affect on how the turbo builds boost.

haha nope
aim is 300hp so not going smaller turbo

stock manifold was cut and a V-band clamp was welded on. will do a tubular manifold when i have money.
piggy bank is **** seeing iv had my head redone with all new parts

new
3 angle back cut valves
valve stem guides
cam bearings
port and gas flow
all stretch bolts
ARP head studs
lifters
injector seals

should do 300hp now

[BIGMIG]

All sounds like a healthy plan.

Let’s keep this thread clean and on topic. Create a rides thread of your own and post some pics of your progress.

This sounds like a great build man. Create a rides thread and post some pics. Keen to see what that head looks like now.

thanks bud
still new at this page thing so ill try and make one when im done
still need to do some mods on the looks of the car
