9 psi is wastegate pressure for a TD05, you won't get lower than that. Expect 12 to 13psi.
Yeah Walbro. Piss easy job and nice and cheap too.
Curious about your coil setup.. Individual coils or wasted spark modification, could you post a pic @THUNDA?

I have a spare Silver WAIC, will check for any wires when I get home tonight
Top right hand corner. These were blanked off on the Prodrive rally cars, see below.

Fuel pump upgrade should be mandatory when raising boost in these cars.
Yellow injectors were featured when the EJ20 went to the under intake manifold and only in the STIs. Besides that anomaly WRX which I can't remember the specs of - came with a VF roller bearing Turbo.
Pull the coils out of the heads for a proper inspection, call Speedlab with details about the chip to rule it out as suitable for 440cc injectors or not - I'll go on record saying that it won't be, they are an upgrade for RS/GT and early WRX with 380cc injectors. Faster to do this than have it checked for AFRs.
Swap out the afm with a known working unit, and look into the conotion of the Turbo.
Re: Plug - the one in behind your retro fitted power sterring pump, will have been the speed sensor plug that would have been on your original PS pump most likely, the wires I'm not sure about, the only electrical stuff on the intercooler in that location were on the silver WAIC, which was a level sensor.

sorry for bumping this thread but a year on, hows everyones opinion of TP? especially interested in comparison between torque performance, possum bourne and dtech.. and then any others in auckland area (i know dtech aint in auckland but its so highly spoken of around here). my priority order is : good tune, price, local. being in west auckland, TP is very close by so i count that for something too (return trip to dtech is about $150 of petrol + 5 hrs driving) but all the times i drove past i just see hondas, alwyas thought it was just some kind of honda dealership until now.
Give PBMS a call, I can't comment on their Tuner - I've not met him, but Julius the manager is pretty approachable no harm in giving them a call to allay any doubts, 40 mins to them from here in Onehunga - so a wee bit of a trip from out West, but nothing like Tauranga.
They have a nice modern dyno cell, that they bought from Speedsource, fully setup for Top mount coolers and external wast gate exhaust, and i imagine their pricing is very competitive as they are wanting to establish a good customer base and reputation.
I'll be having mine run up for boost setup after a Turbo swap.

TD05 is universally considered an upgrade from the VF8.
You current ecu is suited to the TD05, and runs 12.7psi and makes about 260hp.
TD05 has a 9 psi wastegate spring and the VF8 will have a 6 psi wastegate spring, if you rely on the ecu to control boost, then not running the correct ecu for the Turbo will result in poor boost control.
Easy method to circumvent this if needed but - I would stay with your current setup.

Why do you want to install a Turbo timer?
-
Just put it in; Run 98 octane and keep an eye on boost levels, it may overboost, possibly in the higher gears.
If so, you can remedy this.
Been done before, time and time again. This is where you look at an in tank pump upgrade and split fuel rail.
-
It will cost you about $1400 for new bearings/seals and replace syncromesh. That\'s including removal and refit.
A new clutch wont add much more in labor.
You could try a gearbox additive. Once again - not a cure - but may improve shifting while you figure out what you want to do.
Will you still bring it to the meet?

Hi team got my new toy on the weekend need advice
Crunches into 3rd and 5 th everytime you change no matter weather doing fast or slow up or down.
Has a hesitation at 3k with nil bost in any gear like 5th at a hundred give it gas and it sorts it self out.
Just started a weird noise below left head light - inter cooler pump?
Did the previous owner not inform you of these issues?
Besides stripping the gearbox and refreshing those particular synchros; you could drain and refill with a premium fluid - I would recommend Motul Gear 300 or similar market competitor, this only disguises the problem. Or may make it more noticeable.
As Koom has pointed pointed out, Have a thorough look at the all of the ignition system - Pull the coils and inspect and change the plugs during. Perhaps look into a coil upgrade if these are stuffed.
The intercooler pump is located under the passengers side headlamp. Turn the key to ON you should hear the Pump running. Probably needs new bearings easy to do or go find a 2nd hand pump at pick a part.

Yes there is an SA WRX and the tune will be about 1 Bar.

Wouldn\'t bother with the td05. I had one on mine when it was stock and they are so laggy its like 4-5k before you see any decent power. If you do go td05 the grey injectors max out right on boost cut so it\'s not really "safe" either. A tube-able ecu with yellows and a td05 or vf23/24/28 could be the best "bang for buck" mod. td05 are a good turbo though so you could try it? I\'ve had other say they\'re really good but when in there cars IMO not that great. An sti wipes the floor with them in reality. (I\'m talking a stock bc legacy here with ej20g engine and factory ecu)
MY PICKS
Upgrade to the wrx v1-2 intercooler with a straight inlet td04 and a modified intake. Freeing up the intake and exhaust is pretty beneficial. You could also cleanup the factory headers make sure there\'s no exhaust leaks. The up pipe can be changed to one without a flexi in it. The downpipe and exhaust to something without cats in it. An aftermarket electronic boost controller to run about 13-14 psi. There\'s a chipped ecu on TM for $60 at the moment. Or you could get a possum link/apexi power FC/link g1-4 if you want to spend some real $$ on the car.
Some might disagree with the td04 but they are a good wee turbo and have a nice low range punch for any normal road car. They keep up with the td05 as well I\'ve seen this in person. Td05 is bigger and better but the factory ecu will only give 1bar before cutting out anyway so real gains aren\'t seen from the td05 unless you can get an A/M ecu/injectors/intercooler/intake/exhaust.
V1/2 Intercooler would be a downgrade. Even with a larger scoop butchered into the bonnet.
Most likely the car will be running a VF8; which is slightly larger than a TD04 - boost threshold and lag would be negligible between them.
Best thing for these cars would be a proven chip upgrade with the only other modification needed would be an uprated fuel pump.

Stars and stripes motorsport?

I\'ve seen the wagon in person.
Very tidy, and very nice color.

What was wrong with the black rs that wasn\'t running for 2k?
Maybe something simple and leaves a lot of money for potential and likely issues as time goes on.
As everybody has stated. 6k for that RS is too much.
-
Sorted. Thanks.
-
As above, does anybody know how much the front diff takes in the above vehicle.
I\'m guessing 1 to 1.5 liters.
Also your recommendations for a GL-5 oil for these boxes.
Thanks.

Somebody should make Marky a moderator.
Most sense out of anybody in a longtime.

They\'re competitors in the same market segment. They\'re both a very similar-sized, very similarly powered, designed from the same background, similar concept.
But comparing the BC head to head with the GC is much more difficult, especially in stock guise you\'re comparing a much heavier mid-sized family sedan with (particularly in the STI) a rally-bred sports car. The STI has more power, better handling, better looks (IMO), a vastly more modern interior, stops faster, goes faster... you name it, apart from "fits stuff inside it" the STI will do better (actually the Legacy, depending on the ratios, might have a higher top speed. Maybe.) I\'d probably even pick an STI over a BC in terms of comfort and quietness. It\'s not really a comparison when one car beats the other in every single measurable area.
So we are comparing standard performance then. I which case I agree.
My point is that technically both are more or less the same. Yearly and model research and development aside.
Do you actually know the kerb weight of each vehicle?
-
but you cant compare a bc to a STI impreza so it come down to 2 things #1 price- how much he is prepared to pay so like 3k for a bc or 8k for a STI and #2 personal choice- depends on what he likes/wants the most.
Why can\'t you?
You can compare a Evolution to an STI and they are two technically different vehicles all together.

What is the car and what is the Turbo?
