Any ideas for best adjustable fuel pressure regulator to fit a hatch 2009 impreza ( to tame the Bosch 044 pump on idle ! ). Turbosmart, Fuellab?

And where to plumb it in to - there are widgets on the fuel hoses, not sure yet which goes where, especially as it has a swirl pot and the afore mentioned Bosch 044 fuel pump under the bonnet!

Thanks

what advantage will it give?

Hopefully it will stop the OEM fuel pressure regulator "passing" and being defeated by the high pressure / flow of theBosch 044 fuel pump.

On idle, light throttle, the std reg may not be up to the job so overfuels.
Think I got that the right way around.

Also aftermarket FPR will be adjustable for fuel pressure to trim pressure at the injectors if needed.

Just wanted to report in with a review folks...

After some weeks investigating the clutch / flywheel options for a 390/430 hatch I tried something USA

I went Competition Clutches 2100 series Stage 2 single plate carbon / Kevlar clutch with their matching lightweight flywheel. It is rated at 490lb so it's got some slack on what I'm running right now.

Having worn out an AP racing organic clutch which lasted 20k at 365/365, I then moved onto the Helix organic single plate which lasted 10k at 390/430.

The AP is rated to 350lb and the Helix 370lb. They do take more but wont last v long if that happens. In fact the helix struggled from day 1 - shame.

However the CC package has really surprised me. It is now 650 miles in and has been super smooth and silky from the off. With a fairly strict running in policy of 500 miles I adhered and now it can be abused - it has been faultless.

I had expected a heavier peddle - nope. Maybe weird feel - nope.
Incredibly oem feel and bites at the right point. The Helix always felt high IMO.

I hadn't planned on the lightened fly as I wanted to skim my 10k old one - but the garage were such clowns offering me a rusty piece of crap as 'this should be alright' - I said not a chance. I'll take a new billet one thanks.

So pulling away I stall. At the end of the lane I stall.... But not again.
After three weeks you change the way you drive and it's normal again.
The difference in pick up in the lower gears is considerable, a fair bit quicker - so 'on the boil' its a riot , esp on single land roads. You do lose the heavy/ lazy feel the 2.5 gives - it now feels like a 2.0jdm. But with some real clout.

So when the power gets 'up there'. You don't have to go twin plate. The CC option is an excellent option - well priced £400 clutch and similar for the fly. Both are vey well packaged and well presented bits of kit.

So far I'm well pleased. ��

And... I've finally got another bag of bits to take down to Enginetuner (long time no see boys). This time I have a shining new billet turbo Blouch dominator Xtr 2.5 8cm hotside, third generation wheel (aka SC46 'ish), plus a DEI titanium blanket, a new to market Grimmspeed top mount intercooler in black heat dispersant finish (rated upto 550bhp), new air filter for the Forge CAIK, and a DW265c in tank fuel pump.

Should all be done by Fri pm with Martyn Jeffries mapping mastery being the icing on the cake. Prob going dual V power maps as I got fed up using meth.

I reckon an easy 450/490 ? We'll see....

If this top mount is as good as they reckon - Enginetuner will sell a shed load of em.
Remembering the Grimmspeed stuff is generally VERY good and v well engineered.

Report back at the weekend. O happy dayz. Lol

Lots of info on the Grimmspeed site on their tmi

I've just noticed that my mirror direction & folder switches don't light up, on my 08 330s,i've checked the wiring & can't see anything untowards, is this a fault or do they not light up ?. It seems strange as litterally everthing on the interior illuminates, even the sti badge on the ctr console.

Sounds like you're having some serious fun to get through clutches that quickly

How much labour is involved with a clutch change on one of these?

Abx

No, don't light up, annoying I know!

Usually about £300' worth - four or five hours ?

My head gasket went last week, id saved up and decatted the car and got a safe map from andy F purely to protect me from piston failure, anyway a few weeks after i noticed id used water and suspected the gasket, confirmed after the coolant boiled over and didn't settle, i took the car to chevron for them to inspect last week and they have the engine now and the block with the machinist, im going to forge the pistons while shes there and go for a cosworth gasket, trying to keep the build sensible as im not after big power, il max out the turbo and that will do for me. Unsure exactly of engine spec but id say il keep stock rods. What do these turbos run out of puff at? And is worth changing the compression? Also i need a new clutch so chevron tell me, whats worth sticking in there? AP?

I had an AP organic racing clutch on my classic, years ago.. very pleased with it. think it was about £750 back then

ericooper

Thats what Simon recommends i think, near as dam fit and forget, expensive outlay but out last cheaper versions

and never missed a beat when I went to SANTA POD

My VF48 maxed out at 390.8bhp. You can squeeze it a little more with meths.
That's with supporting mods... On a basic zorst and filter you'll get a genuine 365'ish.

AP organic good at this level as long as your lbs don't go too crazy. I've just fitted a Competition clutches stage 2 carbon/ Kevlar clutch which is good for 490lbs. It's v smooth oem feel.

I understand compression ratios don't want to be played with ...

Good luck. A

There's a lot to be achieved from running the right compression ratio. I run 9.1:1 which is quite high for a turbo car, However off boost it drives incredibly well and the pickup is phenomenal... 500ft/lbs by 3900rpm what's not to be liked about that.

but by running a higher comp it's essential to ensure yo always run the best fuels you can.

my vf48 maxed at 380bhp on straight v-power & 420bhp on 16% methanol. it went ok but goes even better nowadays.

Enginetuner tales part 7..... probably.

Spent Friday down at Enginetuner in Plympton - a lovely 570 mile round trip.
I was booked in for new turbo, intercooler, fuel pump and a few ancillaries.

As ever their garage had a few very tasty cars there - a beautiful Dax Cobra replica which they'd sorted and brought it back up to a very high standard. Also of interest was a 1970's style Beach Buggy - 100% fun machine looking very worn but in for a list of repairs for its MOT. Plus engine-less Evo's and a nice selection of Imprezas - a superb blue hawkeye running 600+, a beautiful classic with twin zorsts (soon to be 600+), Martyns drag machine (650 nitrous classic) and various others including a Prodrive styled bug Sti (always liked those) and a few classics to boot. Also good to see some bread and butter work - a couple of tweaked Seat Cupras.

Big thanks to Alex and Paul for working on my car��

I'd brought with me a Blouch 2.5Xtr Dominator turbo with 8cm hotside. Alex fitting it commented on how it was slightly diff from the many SC 46's they'd fitted. Had to grind the turbo just a tad to stop it rubbing on something or other - and bend the water feed pipe a little - and it was on. I was actually a little excited.

Next was a 'new to market' Grimmspeed top mount intercooler I'd imported from the USA - the only one in the UK right now. I'd bought in sprayed up with heat dispersant black coating - pretty much identical in size to the existing oem tmi but maybe an inch thicker. Should be interesting. It needed a bit of work to fit nicely, the fact that my inlet manifold sits on 8mm phenolic spacers didn't help. But with a bit of squeezing and manipulating - on it went.

Next up Martyn Jeffries - mapping maestro extraordinaire - we talked about my car. Road car - twin maps being one high boost and one low at actuator pressure. So onto the rolling road, laptop plugged in , fans on, and twenty pulls and an hour or so later (remembering Martyn previously has mapped my car three or four times in diff configs) and he's happy. The fuelling is good, temps are good, nice curve and twin maps on.

Final results. On 1.6 bar dropping to 1.4bar - 452bhp and 454lbs
On 1.2 bar dropping not much at all - 416bhp and 420lbs

So how did the new top mount fare after an hour on the dyno and all those pulls... It was stone cold to touch. Not bad.

When you consider a decent Perrin front mount is £1500 + fitted - the Grimmspeed tmi is a bargain at half the price. Enginetuner will sell lots of these I reckon.

We could have pushed further with a touch more boost to crack 460 but tbh this is my daily driver and everything is not pushed to the ragged edge in search of maximum power. We have stepped away a little - to a safer and probably more durable place. I was very happy with the outcome.

The drive home was amazing - ballistic is the word. How the power comes in so fast and hard is amazing. And even today I can't tell where it's coming in and spooling to when - as it's so incredibly smooth. No discern able transition. I'm sure there must be a step somewhere but right now I can't find it.

From 391 to 452 isn't so much of a jump... but the way it comes in so fierce and brutal is brilliant. Instant punch with knockout ability.

Why travel so far to get this all done... Enginetuner are one of the very best out there - and I've tried quite a few. Attention to detail, expertise, and understanding what I want (not an outn'out track car on maximum everything) - they have scored high again. Good job.

Alan and Martyn are top blokes. Highly recommended.

can someone help i have been looking at a set of xxr 530 wheels in 5x9.75 will i need any work done to the arches and will i loos and handling porformance with this what size tyers would you recammend ad well

staccato

I've got my STI up for sale at the moment with a view to buying something even more ridiculous like an M5 or VXR8.

But I've also toyed with the idea of going further with mine and strengthening the engine. With strengthening the engine I guess it's only polite to swap the turbo, and then with that I guess a new clutch??

Does anyone have any idea on build costs and what's required and what's not required? Are we talking 2k, 3k, 4k or more??

Thanks

thenewgalaxy

Stock STi clutch should be good up to 500 torques or so provided you don't abuse it.

If you're after 400bhp then you can probably get away with a new turbo, forged pistons, bearings and uprated head gaskets with studs with remap. £2-3k I reckon.

In terms of strengthening the engine it depends what figure you want and how far you want to take it. In my layman's opinion if you're going to push the engine to over 450bhp you're looking at a minimum of forged pistons, forged connecting rods, a set of race bearings, uprated oil pump, uprated fuel pump, injectors, air intake, turbo, probably a front mount intercooler. Oh and a remap. I'd say you'd be looking at £6k+ for all that.

Best get chatting to some of the highly respected engine builders if you're up for that...

thenewgalaxy

Excellent story mate, I think you hit the nail on the head there with the description of the power. So many people are obsessed with headline figures but response and reliability are far more important.

Good to hear another vote for Alan and Martyn

I'm just about due for a new set of tyres on my 330sstd suspension, with 18" BBS alloys, whats the biggest i can go over std (245/45/18), i'm sure i read 255/40/18 will fit without issue.
