My EVO 8 MR tune-up

It's ok I guess.





(Love it)

Nice shot of the car on the Karussell section of the Nurburgring.

loved reading this thread

I've been making a few changes recently, and as a result, have some "hardly used" parts for sale if anybody's interested.

Standard Evo 8 steering wheel re-trimmed in Alcantara with red centre stripe. (very nice but I didn't want air bags on track when wearing a helmet and using harnesses so this wheel is much better suited to a road going car.

Kakimoto GT1.0Z Racing exhaust (cat back). 103DB, 1mm thick stainless, 8kg, one bend, best exhaust evverrr, and lightest steel exhaust on the market. It pains me to sell this. I'm literally hesitating as I write this, but the truth of the matter is, it's too loud for most UK track days. Agghh man. Do I keep it anyway? i dunno. Offers welcome.

I have MR front and rear seats for sale too if anybody wants a black leather and grey alcantara interior with ralliart logos. condition is good.

2018 update. After 2017, it became apparent that I needed to get a lower intercooler pipe custom fabricated and clamped to the j pipe and intercooler to prevent the pipe blowing off under extended hard driving on track. I also needed to address breathing, so the valve cover got replaced with an aluminium one and AN-10 fittings welded on. The OEM design of the PCV system has been retained with a custom fabricated, two oil catch can set up on the "on boost" side, with the "under vacuum" side recirculating to the intake manifold as standard, but using AN-10 line and a Redhorse Performance AN-10 check valve. Due to the immense vacuum leak that AN-10 lines create when plumbed all the way back to the air filter (so the turbo provides a venturi effect to suck the pressure out the crank case on boost), there is also a Redhorse Performance AN-10 check valve on this line that runs through the cans too. There's a lot of threads on oil catch/breather systems and my take on it is this. It's a road going car, used on track. It's not a full-time race car, so sticking with mitsi's design is probably best. We've just made it bigger and better. The fuel pump has also been upgraded to 400 litres/hour and a radium fuel rail, radium damper, fuel lab pressure regulator and syvecs fuel pressure sensor installed and wired into the syvecs s6 ecu. The calibration has been re-done from scratch, making a lively 535 BHP and more torque too, although I don't have the numbers just yet. I should have it back this coming week, when it'll get a new set of APR wing mirrors at which point it's ready for it's 3rd annual pilrimage to the Nurburgring and Spa.

Here's a pic of it having a little drink between map tweaks on the road yesterday, and one of some of the engine bay adornments (fuel damper not shown)

Thanks to MG Auto Motorsport, JR Fabrications, SCR and Syvecs for their shared passion and meticulous attention to every detail. It's a build that everyone can be proud of, not just me the owner.

This is the reliability level I want the car at for my annual pilgrimages, hence capping the power at 500 BHP too.

The Stack Pro Control oil pressure and temp gauges are set to change colour as I ascend through the degrees celsius, ultimately flashing red at me when things start to get out of hand.

The air con has been fully removed so the weight up front should not change a great deal either.

The HKS oil cooler is designed to compliment, not replace the oem one anyway. It's just that I'd already replaced the oem one with a 10% more efficient mishimoto one.

Hi
Hope you car is going well I came across this a while back on the twin oil cooler setup have you find much difference and benefit in the second cooler set up?

yeah, car's still going strong. three trips to the ring and spa, driven once a week on road. it's a beast. oil supply is the achilles heel of 4g63's, built or not. another cooler is a bit more oil in the system. i'd like to fit a racefab sump too at some point.

just read this whole thread whilst sat at work.... great read! I have same car but with obvs less done to it. Well done for keeping up with it, given me a lot of ideas and most importantly, the motivation to get my a**e in gear and get mine done! Enjoy!

Brand new block from Ross?

May I ask why you’ve gone Stroker? Did you not feel the straight 2l was sufficient?

Will you be selling the rod jobbed bottom end ?

Yes, I have a brand new 8MR block from Ross. My current MR block has not had any machine work done either, so it's still got all the meat on it, and I'll be keeping my existing bottom end on the shelf as a spare.

The new build will be based off a cosworth 2.2 stroker crank, but with a rod length that will retain (as close as possible) factory rod angles when the pistons going up and down in the cylinder. Nothing wrong with a 2 litre tho. Nothing at all.

No. My existing 8MR block has had no machine work done on it at all, so I'll be keeping it on the shelf as a spare part, along with the oil pump, fluidampr, existing rotating assembly etc.

Just a quick "reach out" to the evo community here. With working away and no foreseeable use of the car over the next couple of years, I'm considering selling the car as is, and would obviously want to give first dibs to the owners club here where it's much more likely to go to someone who understands what they're getting and much less likely to fall into the hands of a spoilt 19 year old as an expensive Christmas present that he'll only go and kill himself in by New Years. So if anybody is interested in the car, PM me. I have a bottom price of 22K, I'd certainly keep it rather than let it go for less than that. If I do decide to sell it to the wider world at large, I'll probably put an ad on Pistonheads next week. ttfn
