Ok the first mod I did was to upgrade the intercooler to a STi7 one, bought of eBAy for a bargain. I believe they are about 20% bigger than the standard unit.




easy to fit, ecu thought it was interesting and drank a tank of fuel in about 150 ish miles but then settled back to its usual consumption.

I also fitted the samco inlet hose at this point too (bought for a bargain of course)

right decision time, what to do next!

after various searches and constantly watching the 4 sale section and of course eBay

next item fitted was Hayward & Scott 01- full system

decided to not go for a full 3" system but 3" downpipe with 2 1/2" system



shown in the pic is also the OBX headers from the group buy but these were fitted much later

 

ok novembers rolling road results with exhaust fitted

MY01 - 226bhp/196lbs torque

 

now at this point I decided to search for all the bits I would need and the shopping began!

all these bits were to give me my target of 300+ bhp

fuel regulator
up rated fuel pump
Turbo?
Which filter/intake
oil catcher
flywheel
injectors
samco's
earthing kit
knocklink
boost gauge/pod

 

While waiting for all the bits to turn up and finding out I had fitted incorrect pipes to my turbo and was only doing 0.7 bar boost. Time for another rolling road, oh and throw in a dawes device just so I don't come last as usual

just to add a green panel filter was added at this point and earthing kit

252 BHP
194lbf-ft

right finally decided on a TD05 turbo converted to front entry

turbo turned up second hand looking like this



and came back looking like this


TD04 on the left

TD04 on the right

 

Interesting that you lost a bit of torque but gained power? would have thought that the torque figure would have gone up with the dawes.. lol

Makes the next bit more interesting

R.

 

right bits turning up fast and furious now

decided to change the front pulley to one made by perrin


new and old


very easy to fit no need to remove radiator, just loosen belts/remove and stick car in 5th gear remove old pulley and fit new. You will maybe need 2 ppl and a good torque wrench.

iridium spark plugs fitted aswell, bought back from canada for 1/2 the price they are here!

samco MAF hose fitted, shame had to buy this from the usa as samco were very un helpful, as in they didn't make it! but they obviously do

so time to get the fuel system ready for the big day

I feel fuelling is very important so went for the best

fitted a SX regulator





fitted up rated fuel pump on the same day, much easier to do with the fuel system already de pressurized

[Edited by fuz - 1/28/2004 10:50:32 AM]

 

apexi intake and greddy oil catcher fitted, samco inlet hose removed.







main breathers



oil catcher lacated on right hand side



pipes connected to catcher



just a quick check before it all goes back on



right all finished and not a garden hose in sight



[Edited by fuz - 1/28/2004 11:43:40 AM]

 

So the big day has arrived

fit headers

OBX headers wrapped and ready to go on


headers almost on and ready to blow


fit injectors



fit turbo

remap

all in one day

the turbo

the clearance of the water pipe underneath the TD05 as tight and needed adjusting with a hammer
the top water hose needed hammer adjustment too as it was in the way of the intercooler.



The TD05 has more alley on one side of the housing than a TD04 and this needed grinding off to clear the engine, you can see this on the right hand side of the picture above just above the waste gate actuator.

you can not reuse the TD04 water pipes as the fitting are bigger as is everything on the TD05

The headers

These take the longest to do, not fitting them just all the bits of armor subaru fit round the oem ones. Especially where the up pipe connects to the turbo.

when we fitted the turbo we connected the up pipe to it, to make things easy

now a lot a ppl have had problems with the OBX headers, so did we. The bolts provided to connect the headers to the up pipe in our case were no ever going to get tight enough and when we started the engine they were blowing, not a major problem as good old subaru always leave you with a big pile of nuts and bolts left over when you do any modes so we reused the nuts and bolts from the oem headers, job done

smoking time

 

the injectors

very easy to fit but only once you have removed the radiator header tank various armor plated covers and the washer bottle
then remembered how it all went back together again

purged the system adjusted the fuel pressure, turn the key

the car started all ok not even a cel light scary stuff, 380 to 505 injectors with out any complaints.

so mapping time

well you don't want to hear how we drove around @ various national speed limits and set up the car do you

so here is the results


readings are for a third gear run

car still needs a bit of adjustment as there is still some knock detected in 5th gear, but no rush as the turbo is getting bedded in.

[Edited by fuz - 1/28/2004 11:31:50 AM]

 

so did we do it all for 2k

well we did, once you take into account me selling my prodrive backbox, spoiler, TD04 and inlet hose. Buying 80% of the parts from the usa and canada, group buys and ebay.

Fantastic mate, well done

All on a WRX too.

 

Congratulations, very impressive.

Sonu

 

How come on the original rolling road readout you got less than 200bhp?? i thought they were at least 215 as standard? with roughly the same torque figure?

 

VERY impressive

want more info about the mapping tho - what did u use and who did it?

pity u didnt do a few before/after 0-60s, qtr miles, circuit laps etc.

awesome result tho for bargain money

 

the original figures were @ a group rolling road and as always lots of Controversy surrounds it lol

I will dig out my 1/4 mile times from the pod from last year, goood idea

 

14.8 secs
92.5 mph (kept it in third all the way)
1.3 reaction

MY01 WRX

lets see what we get next month

 

Fuz,

Cool report - interested in the oil catcher as I suffer from IC oil contamination. Where did you get it, is it easy to fit, did you really use garden hose and how much approx??

Also interested in where you got the TD05 from and who refurbed it for you?

Too many questions

LoFi

 

talking of the oil catcher just had a lateral performance clutch and my fidanza flywheel fitted so intercooler had to come off, pipes were as clean as a ............. with no oil at all

 

Very impressive Fuz!!
Where did you get your front strut brace from? Is it a genuine STi one or a replica? Did you notice any difference after fitting it? Am considering one for my 01 wrx!!

Cheers

Nick

 

strut brace is one of the ones off ebay (uk) £60-£70 + delivery

car feels alot better looking at getting the rear one when I see one at the right price

forgot to mention also fitted

Aps intercooler splitter (JW )
pro race 1 17's (TSL )

since last update

now working on moving hot pipes away from Apexi induction unit at the moment and boxing it in should be done by next week will post pics etc then

 

any reliability issues?

 

believe it or not my boost solenoid has packed up

I have now fitted a 3 port but i'm waiting for you could say adjustments to my map

no other problems apart from the uncontrolable when driving

 

ok todays 1/4 mile time 13.2 sec 103.17 mph santa pod

1.848 sec to do 60 ft
5.473 sec 330 ft
7.931 sec 594 ft
8.469 sec 1/8 mile
10.952 sec 1000 ft
