They're H&R I love it, some on 197 forum think 25mm is too much, I was considering another 5mm on the rear LOL

Fitted some 25mm spacers this afternoon. Much happier with the way it sits and fills the arches now!

The brass bush makes the most difference IMO, the rest if just freshening up worn parts

when i clean them up, I send the pistons to be weight matched with the rest of the rotating assembly. Usually a few minutes with some 1200 grit and some scotchbrite is more than enough though

You can see in this picture, the sharp edge of the squish has become a focus point for detonation

surface area of the piston crown doesn't really directly effect power. softening the sharp edges is a worthwhile way to reduce detonation risk, det will always occur more easily on an edge, which is why you often see damaged squish zones on the head. The example above has gone a bit too far...

yeah agree with that, I know that bit of road fairly well (right near my sisters flat) and being in the right lane can be a challenge, then you realise you need to change lane and can't get across to where you want to be.

Ugg pretty much exactly as you said, just crush it a bit at a time in the vice until you get the desired shape. I tacked it together then adjusted a few areas with a hammer and drift

Luck of the draw. I could have told you if more if the cams hadn't been removed before I got it back

I easily get mine down to 25/26. It's actually worse when you get onto open roads for me, mpg goes down where it would go up in any other car. Bizarre

pulled the head off the short lived hero engine. 8 bent valves......and a secret history revealed looks like it's dropped a valve head and someone has fixed it, but left one piston that had a BIG dent in it. Would explain why it leaked so much from the rocker cover when it was in Adams ph1...

do you mean a ph1 mk2? and a ph2 mk2? if so they should be the same if they are both off cars with dual lambda sensors. A mk1 is a completely different car, so this will not fit

my Desire and Sensation XE were both great on the factory software. They ruined the Sensation with the jump from 2.3.4 to 4.0.2 3G searching is what kills them, they don't seem able to just sleep if there's no signal.

no, this was definitely a very thrown together attempt, I do actually know what i'm looking at ;). It hadn't been done long by the look of new bits. Just to repeat again, they don't fail unless there is something very very wrong.

starter motor is also in the same main power loop

pmsl, why would I make it up? the nitrous one was Ben's white 197, it had overheating issues for months, took the head off on his request, to fit ARP studs, and it had very clearly breached the gasket and the blow had caused a minor errosion which made a light skim necessary. it was internally...

if it really is the dephaser, then it can't fail, it will just be noisy, and at worst be down on power and a bit jerky to drive

just got back from a stag do. mondays job

I've seen 3. one had nitrous and lifted the head, one was turbo'd and turned the block blue from getting so hot, and the other had under tightened headbolts

I had a flyer come through the door for a bleed nipple repair kit. You fit an insert so the seat is completely fresh. sure I kept it.....

Sounds like the lambda sensor isn't working properly to me

they're an m7 thread so tricky to get hold of, but available if you special order. I'd use Cap head (allen) bolts if they were easier to get

Think you miss heard me. List price is 59.93 each

Air is mostly nitrogen anyway though. 85% roughly

I could list a dozen brands and product that everyone on here gushes over that i've found to be utter guff. Wouldn't stop people gushing over them. Tyres aren't really any different Whom - P6000s are dreadful, I don't know why they're still made. Seems like every car I buy has them on. I've...

LOL, it's like you've read my posts or something.

thats called personal taste, something that seems to elude the internet recently. Tyres and brakes are a very personal thing and just getting what everyone else does is a recipe for disappointment

you say that, but I'm sure you put up a picture of yours when you did it, and you'd got the tensioner set wrong. so it's extremely possible to get it wrong

could be the stat housing/head end plate itself has a crack in it, especially if it's the plastic type

don't think you can run the shift light as alt function 1 is running the vvt (v-tec output can't turn vvt off again at high rpm)
