Explain the MD321 turbo?
#92
Can a standard MY05 STi Type UK take this turbo/power with its standard clutch?
As i understand from various reading other supporting mods would need to be:
650-750cc injectors
New Headers (im assuming i can still keep un-equal?)
Decat system
Turbo
Walbro 255 Fuel Pump
Remap
And then the engine will produce a safe 400/400 on Tesco99/V-Power?
With regards to other upgrades, are the brembos upto this kinda power? (suspension is standard shocks but on STi Pink Springs). Also STi panel filter in.
This just sounds like a perfect turbo (why doesnt everyone use these?!!?!)

Stu, glad you like the exhaust
Not sure if TRL sells them, I know he's mapped a few, give him a call on 01422 241 241.
Mentioning the FP Green is not meant to cause grief but merely give people who require similar power to the T a cheaper alternative if they want to source it them self and take advantage of the $ to the £ ratio

With the MD series, are you not also 'buying' the expertise of the experts involved, UK service back-up to you and the mapper/installer in case of troubles etc?
That must be worth some of the cost?
Great thread.

There has been much debate about the MD321T v the latest FP Green, and indeed they do produce very similar power at the same boost.
However, in independent "back to back" testing, on the same car, the MD321T spooled up 4-500rpm earlier, and had much better throttle response.
I think most of you know just how much difference 4-500rpm earlier spool up will make to the low down torque, and driveability !
Mark.

again dont forget the gt30 hybrid from Alan Jeffery - Engine Tuner
think there all slightly cheaper than the MD series
also RCM do 4 version of a Garret/VF hybrid.
ATP have also recently released 2 Garrret direct bolt-on hybrids, GT3071 and GT3076 ATP TURBO - The Premiere Provider of Turbocharging Components
Would be nice to see some comparisons done of all these turbos. There may even be one thats better than the MD

With regards to other upgrades, are the brembos upto this kinda power? (suspension is standard shocks but on STi Pink Springs). Also STi panel filter in.

Can a standard MY05 STi Type UK take this turbo/power with its standard clutch? - Yes, providing you're not into full-blooded standing start launches
As i understand from various reading other supporting mods would need to be:
650-750cc injectors - yes, 650s are perfect
New Headers (im assuming i can still keep un-equal?) - yes, tubular headers really lifted the performance of my H compared to ported OEMs
Decat system - I run hi-flow sports cat and have just squeezed out 400bhp
Turbo - Yes
Walbro 255 Fuel Pump - yes
Remap - absolutely!
And then the engine will produce a safe 400/400 on Tesco99/V-Power? Should do; I use a bit of NF for extra safety. Obviously at 400bhp, the engine will be under more stress, but I gather there are several standard engines running well at this power output - the key is good mapping
With regards to other upgrades, are the brembos upto this kinda power? - not really; I'm using Performance Friction discs and pads - absolutely amazing! (suspension is standard shocks but on STi Pink Springs). Also STi panel filter in.
This just sounds like a perfect turbo (why doesnt everyone use these?!!?!) - guess lots of people are put off by the extra outlay compared to some other turbos

Marmski - I have the 321H on a standard 03 STI engine. If it's the 'H' you're referring too (I think it is when you mention 400/400) then here are my thoughts:

With regards to the clutch, i dont have the ***** to do full blooded starts even as it is (something in my pockets would start to feel very empty if i did!) but instead get a normal start and then apply the power once the clutch is in.
So by the sounds of it a standard clutch is good for 400BHP providing your not launching the car from 4.5k all the time? (ie: it wont slip once fully engaged)

I'm going to bite the bullet and fit a ScoobyClinic SC46 in February. I'll post the graphs when it's been mapped - which might be the first graphs for an SC46 to be posted on here.

Are sports cats still OK for an MD321 then? What I'm getting at is, if they only map up properly with a decat, that pretty much rules it out for me in the future.

I can't see why a MD321T can't be mapped to say 450/460bhp and be okay. Admittedly you are pushing the envelope.

Why will a MD321T smash a standard engine? There are a number of new age STi's that seem to be running close to 500bhp. IIRC, Andy F mapped a Spec C which ran at SSO.

I think that engine has forged pistons, and rev limit ltd to spare the rods ?

However, my brother was running circa 425 bhp on his STI8 on Standard internals and suffered a ring land failure after around 10000 miles
