Thanks Phil


Question - MD555 I thought this superceded the 321 range ? Also thought it was a single scroll unit ?


But going to twin-scroll - new up-pipe needed, or new headers, or 'much more' ?


Cheers A

I got the car from A690 Cars (formerly GMD) and they assured me that filter and exhaust change would not present an issue at warranty time if some major mechanical failure happened.

As my car is having all it's bits fitted I'm having Andy (my mechanic) do a compression and lambda test to see how fit he thinks the engine is (I've driven it since the magnaflow and k&n were fitted and it felt much smoother - but the standard exhaust is very restrictive).

As for MD555/321 - the 555 is marketed by Turbo Dynamics where as the 321 is sold by Lateral Performance (not sure what the similarities are). My wife's RB5 has had both a T and now 321V and they (esp. the V) are staggering for response and power/torque.

No idea what's involved in fitting a twin-scroll as the 321V meets all Mrs D's response and power needs

MD321 superceded the 555 - that essentially is (or was) an old 321S I think.

The MD321 range from Lateral are proven and perform on a huge variety of different cars.

Have yet to see a MD555 do what it says on the tin tbh.

Fitting a twin scroll requires, turbo, up-pipe, headers and downpipe changes - not worth it when the 321V / T or T+ does the same power. The V is the biggest and that does 2 bar of boost at 3000 rpm - do you need boost earlier than that ?

Cheers Duncan for putting me straight

The re-flash was to cure a problem with the early 08 STI map. The PPP is running a Prodrive map, which should avoid the original issue.

I'm pretty sure the dealers can't reflash the PPP ECUs - they replace the original ECU when you get the PPP fitted.

Anyone fitted the Prodrive mudflaps from Revolution?

Mine arrived the other day but the fitting instructions are for a 03 car. Have they sent me the wrong ones or do they fit the 2008+ STi too?

The ppp ecu doesnt fix the problem either :O seen the damage first hand
the only fix is a custom remap individually suited to you cars engine i'm afraid

Had exatcly the same problem myself, as i thought i had bought 2 sets of flaps for the hatch (knew they were two sets of fronts). Rang up to ask if i had been sent the right ones and was told they still fit, i just need some black self tapping screws!

Wasnt impressed by that, and couldnt be arsed with the hassle of sending them back, so will slap 'em on this weekend when i have a moment. Fortunately i have some better fixings then just self tappers.

OK I intended not doing any mods to my car as I can't really afford to, but the lack of noise etc is really bugging me, whats my chances of getting induction kit, exhaust (cat back), and remap for £1k?

dynamix

Good

ballsie

iTrader: (4)

I'm not impressed with that either if i'm honest. Took ages for them to arrive too

What other fixings are you using?

That surprises me Rob. I spoke with Prodrive before fitting PPP and they advised that the PPP map had all sorts of protection that the OE map didn't have. Nearly everything i have read seems to suggest the problem was OE based

I will try and get this clarified

Not cheap. but I got the OEM Subaru Sti flaps fitted to mine. They are very rigid and formed to to fit the contours of the wheel arch. Boring in black? possibly, but they have got the job done, and add a little extra menace to my metallic grey car.

Apostle

Thanks for the advice / experience guys



And... for others - some 330S (prodrive map cars) 'have' gone bang.

I was told that super aggressive ignition mapping to help the emmissions is the no.1 problem, then that mated to the 'newer piston design' and its a poorly risen yorkshire pudding.

Just got the car back from Slowboy racing last night, ferodo pads and goodridge braided hoses Hopefull the snow will hold off for my mission to peak district this weekend. Can anyone recommend any great roads up there?

Quick update on post ARB squeaks, Neil chased it down to the bump stops on the boot lid rubbing. The increased stiffness from the ARB's is resulting in the body and boot flexing by different amounts. Lithium grease seems to have sorted it for now

Now if I could just figure out what was making my driver's seat squeak I'll be able to hear the voices inside my head again.

I will try get them fitted this weekend, and take a couple of pics. I will have some spare fittings so will send some out if it all goes ok.

I have the same one but I like the standard Sti more, it looks more aggressive and the ugly plastic bar behind the logo isn't that visible with the sti one.

sparkey67

had these on mine when i got it but thorth they where to rigid so took them off & fitted rally armour flaps instead

I cant believe subaru havent issued a recall. Im fed up of being afraid to drive my car in the way it was intended

carlpcross

i drive mine without fear, if it lets go then the warranty will cover it.......

mickp

I totally agree. Subaru should not be sitting back and watching this issue develop. They should bite the bullet and show some loyalty to there customers. The hatch has not been there best seller, so call them in, modify to resolve the risk and set there customers up to want another Subaru when it's time to next change our motors

Remember the days when they topped the J.D Power surveys .

Silence is not the best policy with this one

ed-209

Any other info on 330s letting go. I've never heard of any 330s with the same problem.

Ed.

sparkey67

i rang stan palmers up about ecu, reflash on my car they looked into it & said previous owner had it done at another dealer b4 i got it

i drive mine every day with out fear, i only rang up for peace of mined

Ed. user name Aaron Bird had his 330S go bang recently and did a big thread on it. Search it out or someone will direct you there...

Well, the hatch is back and considerably enhanced -










Better pics to follow, but list as follows -

Recaro CS front seats
Eibachs springs, Whiteline ARBs, rear subframe bushes, front lower brace
Zunsport black grill set
STi copy lip
Magnaflow exhaust, K&N filter

I'm having the geometry done on saturday to complete the transformation but it's already completely transformed - lovin' it!

Andy (my mechanic) also gave my engine the once over and gave it a clean bill of health
