Anyone using a md321t on a newage sti?

If so, what power you reached and with what mods?

Thanks in advance!

Hi there

MD321T should make 440-450bhp on V-power at 1.7bar,on V-power with 20% methanol 480-490bhp at 1.7bar

Usual mods are FMIC,650cc injectors(750cc injectors I would recommend if you will be running methanol),FPR,full decat exhaust and 3bolt headers with Harvey Up pipe,HRC 340lph or RCM 340LPH I would add too

Iv got a decat system and im running 335bhp at the min. Im wanting to get to 370-390. Is the md321t the right turbo for this?

Also what other mods would i need to achieve this?

Thanks

For 370-390bhp MD321H will be better choice or MDX55-400 those two turbo will make this power

Or you can have look too on the SC40 or SC42,both will make this power easily

About the other mods,I would have look on the 650cc injectors,TMIC should be OK and I would add too Harvey Up pipe

Theres a huge host of turbo's depending on your budget for sub <400bhp.

The MD321T is overkill for what you want, but if your not afraid of some lag, and its at a good price it might be worth the buy.

I'd recomment a Billet version though, it makes a HUGE difference.

My S202 is running the MD321T and is making 443 with 800 injectors at 1.8 bar and I'm far from an expert but it seems to do it effortlessly. Hayward & Scott full decat. Andy

All youve got is a full decat system, a md321t turbo and 800 injectors? And your making that power? Thats pretty impressive!

Dont you need uprated fuel pump?

Unless you are buying it brand new good luck bud, i have been searching for one second hand for months, had to settle for a md321S

You will need a fuel pump.

Lets just say Subaru were not consistent with fitting fuel pumps. And for £70 for a brand new walbro from Lateral or a bosh it's a good value and a worthy replacement. A failed pump could be costly.

A 255 or 340 pump is what you need.

Also if your sticking with the standard intake, then a good panel filter is needed, Cosworth or green cotton and good.

I'd also upgrade the inlet pipe as the own plastic one is a little restrictive.

Standard injectors (pinks) would be best supported with a fuel pressure reg, or swapped out for something bigger.

Sorry mate only just seen your reply, yes I have updated fuel pump and a few other bits together with a re-map from Simon at JGM.
