[Sam_Sri]

2011/12 saw the following mods ...

Thanks to Dan Richards these came through the other week



(Vauxhall sticker was added to the cover the next day)

And thanks to hoppydan got an irmcher splitter, which was so well wrapped took a good 5 minutes to get into :L!



Then time to spray!



Finished product


Then after much debating 2 weeks ago i ordered the 288mm big brake kit from LMF Vauxhall, took a bit long arriving but was worth the wait !



lovely size difference!



Then on the car nice filled wheel!



New exhaust rubbers


and braided lines




Also managed to get the new center section on today:




Last summer went for a track day at my local track (Lydden)

Got there and couldnt have asked for better weather but then we also realised are cars were nothing compared to the majority there haha!



Then booked a couple of 15minute sessions and stripped out the bonnet lining, engine cover and front pipe of the airbox just so that everything could stay that little bit cooler!



We then lined up in our group (novice) and the competition didnt exactly match what we had haha!





Then got out on the track












Awful body roll:







Decided to step up my game with the engine performance









R6 carbs and custom 14/16xe manifold with Megajolt ECU and loom, also got a spare near complete set of carbs too!

Picked up a whiteline front anti-roll bar and cavalier rear anti-roll bar. (one of the best handling mods i've done)



Also today came some Gaz rear coilovers! would have got fronts to match but due to price they can wait!



got some rear bonnet raisers and popped them on today, after about 20mins couldnt work out why the bonnet wouldn't line up. After about another hour of re aligning the bolts and various use of washers managed a decent finish





Finally go round to doing my coilovers, what a mission that was smashing the inner arch to shape









Wound them all the way down but was rubbing too much





Clearance

But popped them to a more sensible height

[Sam_Sri]

2013 saw the most mods as i really got stuck in especially mechanically wise

Stainless steel De-cat on



Getting a nice load of pops and bangs! but with the mild steel system it was so loud which has been cured by a piper s/s backbox with mid section to follow





The Piper backbox has been one of the best purchases of this car, quiet for having a 4-2-1, decat, straight through, when around town but then gives a lovely sporty (non-boy racer) sound when you go for it!

After nearly 4 weeks and them turning up individually i finally have my apex front shortened shocks.



Got my stainless center section and got that on at a mates garage...



Also some videos for exhaust sound.... Both these were done from a near cold start (car had been running for around 5 mins) and rev to 3k

This is the old system.. with the cat, hoffman centre section, sportex backbox. All mild steel.

This is the new system. Fully stainless steel manifold back. De cat, non resonated center section and piper backbox.

Replaced the track rod end last week but the bolt shat itself straight away and wouldn't tighten or loosen as cats gave me the wrong track rod end with too short a thread so got the right part for free and then the air grinder came out

Also bagged myself gated underground parking this week and can use it when i need to work on my car so that makes things easier

Would like to thank Daniel119 for the quick posted and very well packed lights

1 week to go!!

Nearly there now, wired in the majority of the ECU earlier with an on/off switch and fuse box, just got to wire the fuel pump, coolant temp, oil pressure light and run a switch to the small fuse box in the PIC for the pump.

Tension the timing belt and connect the brake servo pipe then hopefully she's good to go!



We have power!!!! also found the fuel pump wire and tested it, pump held a solid 2.5 psi which will be tweaked to 3psi.

Couple of better pics...

Although it may seem like the timings out we have triple checked and its not. Thinking it could be due to sticking lifters due to not enough oil

Recently decided to change the looks and going back to old school with Irmscher parts

Got a front irmscher apron earlier for my original bumpers. Will get better pics in the next few days





These are upto date (9-July-13)

Got some time to spend on her tomorrow so will start the updates again

[Sam_Sri]

looking good

Cheers mate ! i look at those last pics and think why am i swapping bumpers and alloys but i know it will be worth it for the end result just want her looking a bit more 'retro again'

At the begining of the week i started de-rusting the slam panel by sanding and treating it with kurust, just awaiting paint now

No pics today as phone ran out of battery down the garage !

Facet pump in, with no fpr at the moment, old fuel pump is out and we just connected a hose to the tank filter then to the rest of the lines.

Holding around 3psi with some fluctuation and seems to drop to 2psi after 4k revs :/.

Glad to say that she's pulling a lot harder now (keeps pulling to 6.5/7k) and still have the carbs to balance and ECU to map so I can't wait for some more power

Also got to drive a mk5 golf gti with the dsg gearbox! Have to admit I loved it! Smooth quick changes and doesn't hang about either!

Pic doesn't exactly show it, but the oil leak seems to be rocker cover and not cam seals luckily



Fuel pump temp mounted



And found this no idea how it happened but could explain why the steering has been pulling to the right?



Still losing fuel pressure when opening up the throttle and to top it off it seems the fuel pump is leaking and not from the unions either :/ fuel everywhere

Slowly losing patients now as just want it running right, looking to get a 4-7psi fuel pump with a malpassi filter king fpr set at 3psi. In theory that should cure any unstable fuel pressure?

What is the picture above of exactly? Looks quite serious as it's a mounting point for something solid. I'd get it welded asap

I'd be losing patience as well but i'd never have went the carb route personally.
Once you get the fuel pressure sorted, you'll still need to get the ignition timing set up properly, then you might need to fine tune the carbs by either adjusting the needles or / and different sizes of jets. Any time you change the engine mods, you'll need to retune the carbs as the fueling will need adjusted and there's no ECU to adjust the petrol input on the fly. Usually it's a case of trying lots of different set ups (carbs out job) to find what set up runs best.

Have you pulled the plugs again recently? I'd do that to see how it's running internally. You don't want it running too rich or it'll coke up the inside badly and too lean it can burn the valves and / or the pistons through detonation.

Can't you drop it off at a specialist and get them to do the work instead?

That's the front left engine mount, will get one Monday when places are open again .

Yeah I wanted to be different but now I'm thinking otherwise! The ECU map I'm not too worried about as I've got the right maps on my laptop but its pointless uploading them till the fuelling is sorted.

I've got some standard jets coming and calling up boggs brothers to ask exactly what size the jets should be drilled out and I'll have them done exact as im not sure how well they were previously done.

As for balancing the carbs i'm waiting on a better inlet manifold to be made up so the trumpets face up towards the bonnet.

The nearest specialist is an 90mins away which isn't too bad but where I go which is where I did all the work they know what their doing .

I just need to chuck one last lump sum of money at her and spend a few long days and I reckon we can get her running properly

Is it not worth doing the ignition map as well so at least it'll help things slightly until the rest of the fueling is sorted?

What does balancing the carbs do? I've not heard that term before..
Remember and tell the guys the exact mods your car has as well before drilling out the jets so they can get a better idea of what size needs done.

They'll be awesome when set up correctly but they can be a PITA to get set up right.

The base map its running at the moment isn't bad at all keeps everything running smooth as it can be, its just the fuelling letting the side down.

Balancing the carbs is setting them up so each carb supply's the same amount of fuel/air ratio.

Yeah I will do, only mods are carbs and exhaust, tempted to get some cams but I'm not sure how much more money I want to chuck at this now.

As you say I know it will be awesome its just going to take time to get there, if this wasn't my daily car I wouldn't be too worried.

Going out now to see what the plugs look like, will upload a pic soon
