Ba Xr6T 5 Spd Mods

[turbroxr6]

hi Ive recently bought a 04 xr6 turbo 5spd sedan with these mods, walbro fuel pump, bosch 42lb injectors, 3 an 1/2" exhaust, 4" dump pipe, 4" hi flow cat. it came with a flash tuner with custom maps which I dont no a lot about. can someone tell me how well my original valve springs will cope. I dont thrash it or do burnouts just every now an then give it a boot full full but not red line it. also with the flash tuner and the original boost solanoid can the boost be upped via just the flash tuner??? I'm kinda new to this so anyhelp would be good.

Defs put a t56 the t5 will sh*t itself sooner or later like mine did :S

You need a retune if you want to up the boost, which, everyone here will advise you avoid until you get a stronger gearbox.

In the meantime don't load it up in 1st, 2nd, 3rd, 4th or 5th and start saving for a new transmission.

Congrats on your purchase. These are an excellent car.

With those mods the valve springs might have already been done (fingers crossed). Some people with mods like yours will say their valve springs were fine, others experience valve float and I have heard even breakage.

The mods you have are already enough to break your gear box and make you clutch slip. So.....as I think Velocity is saying....you probably have a conservative tune with lowish boost to preserve the gearbox and clutch.

I upgraded my gearbox before my mods so I was able to sell the 5 speed and get some $ back. My car is still at the tuners because the clutch started slipping as soon as it hit the dyno. Yes I should have changed the clutch but I didn't because the bloke I bought it from said it was heavy duty (my arse).

FLASH TUNER: If you could state the model of flash tuner, some of the more experienced members may be able to provide more info.

As far as I know you have 2 basic types.

1. A unit that has preprogramed tunes to suit certain power upgrades eg, high flow cat or exhaust, dump and cat or whatever. Some people run these generic tunes for a long time with no problems where as some others are not happy with them. Every engine is a little bit different so it seems to be a bit of luck involved.

2. A unit that allows a Tuner to install custom dyno tunes specifically designed for your car on the spot. The tuner can see how your car is reacting to the modifications you have and tune the car accordingly, taking into account your driving habits. Obviously....this is preferable but is a bit more expensive.

New 6 speed gearbox and good clutch will probably set you back about $6,000 or so. So you will need to weigh that up before you go adding power.

If you're half mechanically minded you can put a t56 in yourself. I got a decent 2nd hand one for around 1700. Make sure it comes with the yoke to suit!

Yes, that's right its pretty straight forward. I did it myself too but I needed a friend to help install the new box as its dam heavy and wont balance on a jack by itself. It also has a different crossmember. Anyway there are some good threads on change over on this site.

don't hang the box either... 300nsomethin for a new input shaft from mal

and the clutch plate can be bent by hanging the box while it's partialy in
