My journey to owning a 386rwkw BA XR6T.

 

When I was on my P's I owned a red BA 2003 XR6 N/A, I could not wait long enough to get my opens so I could have a turbo.

So I was offered a BA 2003 XR6T 4 Speed Auto Blueprint for a very good price and could not refuse.

Once I got my opens I started using the Turbo and sold the N/A to a mate.

 

First of I wanted some new wheels and thought I would prepare for the more power I will want later.

So Matt Black wheels fronts 19x8.5 and rears 19x9.5

Now I chose the XR6T because I had heard of its power potential so it came to the time where I had to start looking at doing my first stage of mods.

I did not want to gain power too cheap so I did some research and I always had a goal in mind of around 300rwkw :)

 

Stage 1 result was

 - Venom 3.5" high flow cat

 - Atomik valve springs

 - Custom airbox with pod filter

 - Walbro Fuel Pump

 - 1000cc KPM Injectors

 - PW Stage 3 Intercooler with hot/cold side piping

 - PWR Tranny Cooler

 

XCAL4 Tuned to 258rwkw with 870nm torque running 14 PSI trailing off

When I heard the power result I was not overly impressed... but then I took it for a drive and it was absolutely amazing! I had never driven anything so powerful before.

I could not wipe the smile of my face.

 

Unfortunately the actuator was sticking so I decided to put a 10psi actuator on and get the turbo wastegate ported with larger flapper.

I got a retune and noted I was wanting closer to 300rwkw so we put boost up to 15psi

The result was 265rwkw with 890nm torque running 15psi

Still not very impressed with the power result on paper however driving with the power felt amazing and even better having it hold on boost.

It wasn't 300rwkw however I was happy... for the time being.

I decided to put it on another dyno to see how different the reads could be.

 

Result 275rwkw with 916nm

One day I was on Gumtree and come across a great motor/club/gearbox deal

2007 BF F6 Typhoon motor with turbo (brand new core, ported wastegate and larger flapper)

Billet oil pump gears and Plaz Valve Springs just fitted.

T56 Manual Gearbox with brand new Malwood Option 4 Heavy duty clutch and flywheel.

 

Once again I had to buy it haha. So now I have the strong bottom end what other mods can I get to make some good power.

More reseach was needed.

 

Stage 2 final result

 - BF F6 07 Typhoon motor

 - Converted from BTR4 to T56 Manual with 3.93 diff

 - Turbo ported wastegate with larger flapper and 12psi actuator

 - Malwood Option 4 Clutch and Flywheel

 - Billet Oil Pump Gears

 - Plaz Valve Springs

 - PW Stage 3 Intercooler with even larger hot and cold side piping

 - PW Throttle Body reloc

 - PW Battery reloc under headlight

 - PW 5" Turbo side race airbox

 - 1000cc KPM Injectors

 - Walbro Fuel Pump

 - X-Force 4" Dump to 3.5" exhaust

 - 600HP Built tailshaft

 

Tuned with XCAL4 making 386rwkw with 1091nm running 19psi on BP98

Now I am really happy with the dyno readout and the power is amazing!

Cant stop smiling again :)

 

Buckled the old wheels so bought some new ones which are same f19x8.5 and r19x9.5

Wanted to start doing track days and those stock brakes are horrid not to mention the amount of rotors you chew through.

 

So I got some XYZ 6 Pot 355mm Front setup570fbfbe486fe_XYZBrakes.thumb.jpg.5bea7f

lovely car mate.

 

Wish I had that style of turboside intake! mine presses against the coolant hose and the filter goes under the bumper so I call it a plazmaman hot air intake.

Yea Ozy it definitely was worth while.

@john definitely believe airbox is the best option, I dont like the idea of the under headlight filter would cop allot of water in rain/puddles

Mind me asking which Walbro fuel pump you went for? Also, love the brakes, they look mean as. Stock BF brakes look tiny even under just 18" rims. 

All good mate its a Walbro 460.

Thanks, they make the front end look tougher haha.

that's an enjoyable modification pathway :spoton:

does it turn a tire?

Thanks mate, this forum is where I found all the advice I needed aswell as some from the tuners.

With 265's on 19x9.5 rears she will kick hard under full boost in first, second, third and sometimes forth with just me in the car. I am using cheap tyres will go some better ones and 275's next and she should be much better.

Well it's been a while... Over the past year I have gone through 6 diff centre bushes and the issue has now come around again. This time no stuffing around.
New independent motorsport rear diff hat, and harrop truetrac while the diff is out... why not.

Now I can't handle getting all this done not to get some more power so here comes the e85 tune!

I'll post an update soon, picking car up on Wednesday :)
