Please do!

original manifold


pulled that off


whacked the new one on


removed dump pipe

tried today to remove the oxygen sensor from the standard dump pipe
no luck even used a snap on oxygen sensor socket still rounded the o2 sensor head off, guess its been int there
to long.

so got a generic bosch single wire O2 sensor (0 258 002 031) hopefully will work ok :/ was only $77
especially since the one on original dump pipe is prob original and getting old.


rough idea what itd look like with new dump too.


better gain something after all mucking around haha

Looks great!

Watch those SS manifolds though, they will not hesitate to crack on you if improperly braced.
I recommend you make a mount from your dump to the block and install a flex if you don't already have one. Together they will greatly reduce the chance of cracking.

Cool thanks for letting me know yea got a flexi
Already

Last weekend pulled my flexi section off.
Because new dump pipe has different flange

Went to a few exhaust places but no one will
Weld the new flange on without the car.

Just wondering if will damage anything
If drive the car about 1-2kms just with the headers
And dump pipe on?

Also was going to whack the jasma pullies
On while the car is in pieces but noticed that
The power steering jasma pully isn't a v belt
Type, so prob have to change the pump or do the
Standard pullies come off the pump?

Things ain't going my way lately haha

And also have to find some decent heat rated
Wire for oxygen sensor

Plus can't check my mixtures with wideband
Cos wanted to make sure running ok with the new
Narrowband 02 sensor.

Many options here:

1. Tack weld the flange, or whatever it is and take it to the exhuast so they can mig weld it fully.
2. Stickytape the flange on, as solid as you can, take it to exhuast shop so they can tack weld an exposed section, than they can mig weld it fully.


I have done both of the above in the past.

Today tried to get further made things
Worse tried getting alternator belt back on
Had to remove bolts for alternator I turned one the wrong
Way heard a crack and now coolant pi**ng
Out can't see what I've cracked something
Near water pump sigh

So after months and months car back together
And runs, but I also had this problem before
When cars idling. Then rev it in neutral
Only revs to 4.5k and you can feel a mass
Flat spot. Would that be crank angle sensor
Problem maybe?

Few weekends ago took car for a drive
Feels ok. But when boost it hard richens
Up way to much and lose power. Used to
Have air fuel ratio of 12 on the wideband
When boosting hard. Now goes all the way
Fully rich on the afr gauge. Wonder if that
Generic O2 sensor not quite suited to my set up?

That cast manifold you removed looks suspiciously like a jawarehouse/gtpumps manifold. if that's the case, they are awesome!

Ever considered an stand alone ECU or perhaps ECMLink? A tunable ecu will solve all these problems you are having and allow for more boost.

Also, pissing off the AFM is all win!

Bummer so I shouldn't of wasted my time
Putting the stainless steel manifold on. Was
Alot of effing round. Lol. Oh well it's all learning I guess.

Yea I got a single board vr4 ecu already chipped
055 airflow meter 560cc injectors pink tops I think.
But I have no idea what to do to tune correctly.
Is the first thing to do when I get holidays
From work. Get it dyno tuned. Also was thinking
Really mild cams less than 272. I spose with more boost
Gonna need better intercooler and piping set up
Way to many silicone joiners. Dammit should've spent
The extra money for forged pistons

How's your beast going?

Found out today.........the factory cast manifold you pulled off is off an EVO!

I would not stress too much about cams, still a bit early I recon.

So your current mods are:
B16g, ECMlink, 560cc, 044 pump, Ex - manifold and exhaust?

I would focus on:
Quality intercooler, as it will allow the 18 -20psi this should be running.
Clutch as you should make 180 to 200atw
Good tune (Steve Knight or the bloke who tunes Bitza)

Also you may need:
MLS headgasket and arp studs if the composite leaks,
Exhaust housing port if the turbo decides to creep.

This thing is going to move!

Have an extreme hd clutch already
And reconned gear box. Hopefully they will handle it
Think those studs where put in when engine
Reconned. Think it's a decent head gasket too
Have to check the invoice.

Just running a soarer intercooler I think ATM
From the blue cordia. I agree need a decent one
And thinking stainless steel cooler piping. So the
Insides can't flake off the the current mild steel ones.

Is 20 the max u can run on non forged pistons?
Maybe 18 safer number?

There are a few things that dictate the amount of boost your engine can run. These include:

Fuel - the higher the octane the slower the rate of burn and higher the resistance to pre-ignition.
Lower intake temp - Air density for increased oxygen and again resistance to pre-ignition. Large quality cooler helps here.
Efficiency of turbo - larger turbo's are generally more efficient at higher pressures and operate at lower rpm to achieve the same mass flow. Because of this, the discharge temperature is lower which results in the same benefits as above.
Compression ratio - Stock assembly means you should have 7.8:1 CR, providing your engine was built using the correct head gasket, this should not be too far off (if not the same).

In the past I ran a microtech Lt8s with no provisions for knock control, your ECMlink is better. Engine ran a ported 16g on 98ron, had 9:1 compression and a 40 thou quench. The engine was tuned with no safety margin and managed 180kw at 17 psi with 12deg ign. The engine would ping at any higher boost and therefore could not make more power. I added toluene to the fuel and the engine made 205kw at 20 psi. It was obvious the engine was hitting the limits of fuel as the little 16g was running out of puff.
Since your compression is lower and the fuel will most likely be 98ron. You can run more boost before this happens to your engine. Generally you minus 3psi per 1 count of added CR for similar results.
Your engine should make good power if the head gasket holds up, but will rely on higher boost to do so. If you are not happy with the power, you can either go for better fuel (e85) or a larger turbo.

Now my brain hurts.

Cheers for the info man. My brain hurts more.lol

Yea apparently with the ecm link u can run
Dual fuel maps so can have one for 98 and
E85 ( that ethanol stuff) get more torque
With it apparently.

Got the full version of ecm link, but don't
Think can use the launch control part of the
Chip unless I wanna pull left into the car next
To me haha.

Last time was dynoed best got was 135fwkw. 500nm of torque
At 110km
Was pretty much standard. And not quite run in.
I'd be happy with 150-180fwkw.

Yea I guess that's why people go for the
20gs. But would they be laggy?

Yea my td05 big 16g supposed to be blueprinted,
Dunno what diff that would make.

Oh and forgot also got custom 2.5 throttlebody
Elbow, and egr block off.

What cooler would you recommend?
I know brad was running an Evo one.
Was thinking of going that way as the car has had
One fitted before.

Your evo16g will get you where you want to be.

A td05-20g will make a bit more power but is not worth the upgrade IMO, + 2mm on the inducer is nothing really. The extra lag should be bugger all.

A tdo6sl2 -20g on the other hand should scream up top. The larger exhaust wheel will introduce noticeable lag, probably 300-500 rpm.

Evo coolers are good, I believe Brad ran an evo 5 cooler. If you do not plan to modify your car any further, go for it.

Evo 3? Think that's what the turbo is off so would make sense.
It's very heavy tho. Maybe should've left
It on was lot off buggering around getting the stainless steel ones on
I better gain something lol. Oem prob more reliable

Reckon go genuine mitsi cooler or an aftermarket replacement?
Mitsi one prob pricey if can still get them.

Would be good to go further but lot of power
For a light car. Are they a bit sketchy to drive
Around the 200kw mark?

Did notice there are some small cracks on my front
Cross member near the bolts to the chassis
Spose should that too. And was advised to replace
Wheel bearings too.

Dunno if the cracks would be because it's bit
To rigid in the front, think the lovells are bit
To rigid might swap back to king springs on front.
Unless the konis need adjusting.

Cheers for you help man appreciate it.
