Converting a Subaru forester

[h4house]

Hi,

I'm planning to convert my Subaru forester 2.5XT (2006) to LPG. I have a Tartarini sequential system I'm going to use for this. Know about the TGV issue and have accounted for that. Got two questions which hopefully someone who has converted a Subaru before can answer.

1. What is the best route for the pipe back to the tank. I thought you had to keep the LPG fuel pipe at least 30cm from the exhaust. Since the boxer engine has down pipes either side of the engine bay, how do you achieve this?

2. Where is the best place to take the RPM feed from for the LPG ECU.


Oh, another cheaky question. What is the size of the taps to thread the manifold for both 6mm passive jets from the LPG injectors and the 4mm feed for the vacuum pipe and flashlube feed.


Many thanks,

Alan.

can be used to protect the pipes if they need to be fitted close to the exhaust.

nozzles are normally M6x1 and drill 5mm. Some systems use different sizes.

Not 30 cm, only 10 which may make life a bit easier.

4.4.2 Pipelines should be no closer than 100 mm remote from the vehicle exhaust system.
Where this is not practicable, the pipeline must be shielded from the vehicle exhaust
system by a suitable heat shield so as to ensure that the pipeline is not subjected to a
temperature above 120°C.

and the filler shall not be closer than 25 cm from the exhaust outlet.

Plenty of room on a forester. They really aren't a problem .

Thanks for your replies, guys. The 10cm makes a big difference! Shouldn't be so difficult after all.

Biggest hassle is taking the inter cooler off tbh. Rest Is nice and easy, oh.... There are two metal plates with acoustic padding covering the injectors. They are a bit of a pain to take off. If I remember rightly there is a breather pipe that is part of the cover on the near side one. But you can cut it off and re use. Or just replace the bit of hose.

Thanks, I had noticed those metal plates over the injectors. Wonder why they were there and so thick..are the injectors that noisy they need noise damping!

I've had the intercooler off before to fix an air leak, so not too phased by that. Been a long time since I drilled and tapped anything (school probably) so I'm a little bit daunted, but will practice on some scrap metal beforehand.

Once done the next hurdle will be finding someone willing to check it over and certify the installation......will cross that bridge when I get there.

Looking at the worked involved, I really can't see how anyone can claim to do a good conversion in one day. It all sounds straightforward enough on paper, but when you get down to the nitty gritty, it isn't so simple. I had a previous Forester converted by a mob in south wales...it was not a happy experience for me. I'm a mild and placid sort of chap, but the owner pushed my patience to the very limit.
