Thanks to Colesy for undamaged front subframe. I will get it refurbished with bushing and swap it over.



Also, on the drive home I hit a milestone

Just tried and no luck. 20mph flat out and same boost is reached at same speed and feels no different.

What about finding the sluggishness. Any luck on that front?

No more horrible squealing, it turned out to be the steering dumper. It was in such a bad state I'm surprised it stayed this quite for this long

Have you a good boost gauge in the car? There is one way to test but you must be very careful. Disconnect the N75 pipe that feeds the wastgate and plug it. Go for a drive and in a high gear at low rpm goto wot. Look at the boost gauge and make sure it doesn't go to high. You Have no boost control so boost will come on fast. See if it responds faster than with the N75 connected. Lift of throttle to control boost.

Be careful...

Don't have a boost gauge ( I know) I'll try it and be very careful, I'm sure I will feel the difference.

Thanks

I forgot my boost testing hose in London, but I doubt it's boost leak. Just feels like something is slow to react is there a safe way of test if it's N75?

Boost leak or maybe n75

Car seems to be a bit slow to boost up, could it be N75? She boosts to 2.4bar eventually, but just takes time. Used to be a tad punchier

[hunker7]

Thanks, loads of work has gone into making it look good

Nice work there, especially compared to the engine bay pic on page 1 of this thread.

After fitting lpg I can barely see the rack but that's a good idea, I'll try and get my hand in there

I had a look, and noise seems to be coming from steering rack, can it be the damper on the rack? Oil level is as it should be.

Get a friend and let him put hands on suspected elements. Should determine the culprit via vibrations. Not 100% though.
