BOSS 290 into BA XR8

Tezbo-BAXR8 · 26-03-2013, 11:14 PM

Hello Everone,

I'm planning to take my Boss 260 out and fit a Boss 290 in place of it. I was told by a bloke at one of the motor wreckers in Melbourne that I need to install a tune or run a Boss 290 computer because if I run my standard computer, I'll blow the engine up.

Can any one confirm or denie this, as I'm not sure if this blokes pullin' my leg or not.

The tune would definetely be different from the 260 to 290, I wonder if a flash of your current 260 ECU would do the trick?

How come your putting the Boss 290 in, just out of interest, obvious answer would be for the power increase?

The tune is different but you shouldn't damage the motor by driving around on the stock 260 tune, they are very conservative. I drove around for about a month after doing my conversion from 260 to 290 before getting a custom tune on the stock computer.

Hi drew 1491,

I'm glad to read that you've done the swap for a 290 from a 260 but sorry to hear that the bearing failed as my circumstances are different.

I'm from Perth too, and just wondering if you don't mind, would you be able to give me a hand with the swap once I source a 290, as I used to have a massive 6 X 10 shed when we were renting, but now we've bought a house North of Perth, I'm reduced to a carport!

Cheers mate,

Tez.

Hi Everyone,

I'm considering all options with my BA XR8 at the moment and I'm not sure which one i'll choose out of a 290, a 302, or a 315. It's probably gonna come down to the price and adaptability of the 315 to my BA's 4 speed auto.

If I run the 315, I think I'll have to have the auto strenthened considerably and a custom tune on my original computer no doubt, but I'm not sure if the motor will run on my computer before I get it custom tuned.

I'm waiting on feedback from fpvspares.com.au and when I've got all the facts and figures I'll keep ya's all posted. Hail the Boss!!:

Tez.

Hey Tez

Just wondering if you went ahead with this conversion. I got quoted $10g from FPV SPARES in Sydney for a 315 conversion with 6sp manual or auto, my choice. That is with changeover with 260, if I want to keep the 260, add another $1500. $11,500 with engine, gearbox, computer fully installed and tuned.

HI Tez, mate off mine has dropped a 315 into his ba ute,still running the 4 speed auto.He also got the ECU with the motor,bought it out of a damaged super pursuit,probably need to shop around at some wreckers.Cheers Geoff.

Hi Everyone,
I haven't been on this forum for about 3 years and I have a project car in mind to build, well an engine swap to be exact. I am in the process of buying a BA XR8 with a 315 motor fitted and I plan to fit it into an FG XR8, If anyone has any advice on this engine swap, It would be very welcome.

Regards,

Tez

Hello Fellow Ford Fans,
Although I haven't been on this forum for some time, I have been squiralling away some dollars and soon will buy a FG GT. I have always been keen to experiment with alloy engine blocks, and making enquiries lately, I've found you can buy a 5.4 alloy block stroked to 5.8 with rotating assembly for around US 10K. Saving for a house deposit amongst other things, it's a bit of a pipe dream at the moment, but I'd still love to make it happen. These 5.8 alloy blocks are 50 kilos lighter than the cast iron cousin.

Regards,

Tez

Hopefully someone is working on it, would be an awesome upgrade.

Whats the going price for a low kay boss 290?

xr6eta · 29-06-2014, 10:15 PM

As per my previous post, FPV spares in Sydney quoted $11,500 for a 315 conversion with manual/auto gearbox, computer the works. $1500 cheaper if you leave your old Boss with them. I don't know if a 290 would be any cheaper and I only got a conversion price because I wouldn't know where to start with a conversion and if I did, I don't have anywhere to do it anyway.

I asked about Coyote engines and they said they could do it but the conversion would be around $20-25K. Don't know if that's good or not.

I won't be doing a conversion for some time but definately want to get my homework done on value for money and bang for buck. I hope you don't think I'm stealing this thread but it appears as though it was done with, apologies if it wasn't.

Any opinions on a 315 over a coyote at those prices quoted, given what could probably be done to a 315 for the extra dollars. Happy to take all opinions on board. This is not for a track car or to be thrashed, I would just like something a little unique and I think a converted Xr8 would probably surprise a few people when the bonnet gets popped, as well the extra power.

Hi I have a 2002 ford f 250 two wheel drive which comes with a 5.4 two valve standard.I have to pull the motor because it has a oil leak on the back of the right hand bank between the head and the block, seams like a common fault .The motor has 220 ks on it. has any body done a up grade to a boss 260 or 290.from the 220.Would all the electrical connections be the same and what other problems would i find?
