what is the best turbo ????? heard alot about the md turbos and alittle about the fp green.....

I want a good 450bhp with not over the top lag. ive got a vf34 turbo which is amazing but having my bottom end rebuilt with forged pistons con rods, uprated oil pump, arp head bolts. 650cc injectors and a aeromotive fpr, got HKS headers, all will be running on eck mapping

just really stuck on what turbo....... please help asap

SSCJAY

The MD321T will get you where you need to be and is a very good Turbo.

Just one thing you didn't mention above, uprated gearbox?

The WRX Box won't last long with over 400 lb/ft of torque

umm i thought i heard from someone that the newage wrx (2004) had quite strong boxes and good for just over 400lb/ft torque. could be wrong

andythejock01wrx

The consensus seems to be 330 to 350 lb/ft, although they'll take more if you don't launch or track the car.

umm, some thing to think about. the reason of not going for a 2.5 bottom end was i didnt want to have to change the gearbox with all that torque.....
maybe i should look for more the 400bhp....

andythejock01wrx

Have you done too much to the WRX to think about getting rid and buying an STi ?

GROWLER_GRRRR

why would you buy a sti 400bhp is the limit for the internal parts on a sti engine , so you still need forge pistons the rods im told will take 400bhp no problem .

na love the wrx. just the bottom end had gone so while the engine is being rebuilt thought why not put a biggier turbo on it.... plus how many wrx have you seen with over 400bhp

hello l33 griff

im going down the same route as you but in 2.5 sti closed block. i had the choice of the m321t or the garrett gt30. the m321t sits in the standard postion where the oe turbo is, but the garrett sits in a differnet postion. the m321t turbo is around the £1400 mark and the gt30 is around the £1000 mark BUT you need a special down pipe and uppipe to suit the gt30. just remember if you are going down the 2.0 road u will suffer more turbo lag than the 2.5.

The MD321T will be more responsive than a rotated GT30R so would be far better suited to a 2.0ltr but be aware it will need to be pushed to achieve the 450bhp target on V Power or Tescos 99, expect to see around 400bhp at 1.5bar

The beauty of the GT30 is the fact that when you decide you want more it's a very simple job of swapping exhaust housings or the whole unit whereas a standard location turbo is a little more difficult to change and you are limited by the space (or lack of) you have in this location.

With that torque, it's a matter of time mate; you're going to need to save up for either a 6 speed from an Sti, or a PPG 5 speed. Budget 2k for the former and 2-2.5k for the latter.

I've just gone from a VF28 on a 2.0L to a rotated GT30R on a 2.5L

I have to say that this combination is far from laggy and unresponsive.

Its incredibly driveable throughout the rev range. Off boost its very perky.

If I nail it though all hell breaks loose.

Its equally as quick as the 2.0L vf28 was off the mark. Plus it just keeps on pulling and pulling very very hard indeed.

Its peaking at 1.5 bar to the redline at the moment. When its build with forged internals, sleeved and mapped to 2bar its going to be astounding!!

However going back to the OP's question regarding the 2.0L. The MD321 series has to be top of the list. I've heard nothing but good reports and Terry B had some fabulous results last year.

well ive decided to give the fp green with a periin 3" intake.

Not wanting to pee on your bonfire but i've heard a few reports that the fp green is fairly over rated yet everyone thats had the md321t has said how truly awesome it is.

My personal choice would be the MD321T.

What sounds like fun ! What power are you getting Darren ?

Its not been rolling roaded yet. Another scoobyneter had his very similar specced car rolling roaded at scoobyclinic at 1.5 bar and he said it made 486bhp. This I feel was optimistic.

I would imagine that I'm somewhere around the 420 to 450 mark at the moment. But I think more of it as each day passes it just gets better and better.

Roll on sleeves, forged internals and a proper remap!!!

I believe the FP Green is basically a TD06 49lb, which are supposed to be good for over 400bhp, Andy F sells a similar spec turbo.
I have no doubt the MD321T is a better turbo but the FP green works out about £750 with current US exchange rates so less than half the price of a new MD.

I have the MD321t on a "wrx" newage, all I can say is it hurts

Tidgy

what makes you doubt it? would have been done on there dyno wouldn't it?

not forgetting the GT30 hybrid from Alan Jeffery - Engine Tuner

hi mate, did your bottom end go? why? miles?
what power were you running?


cheers tim

SSCJAY

The guy was running stock sti 5/6 heads on a forged 2.5, with a Gt30R 486bhp is pretty hard to get @ only 1.5 Bar.

IIRC Scoobyclinic told him it could have been 10% more but the wheels were spinning

Tidgy

never known a dyno dynamcis RR to lie, strange hes says he was told it was spinning the wheels, seen a scoob running 500bhp at the wheels fail to light them up in the dyno, sounds very fishy to me

Tidgy

heres that power run by the way

YouTube - Scoobyclinic car making over 500bhp...at the wheels

andythejock01wrx

Strewth Cookie, and I thought I'd chucked a lot of cash at my car !!

Sounds great though.

The Fixer

the Racing line has mapped loads of FPGreens and for the money you cant go wrong! 450-475HP seems to be the norm for them.

bhp 360 engine covered 36k number four piston melted. reason i think is to do with the bottom end being comletely standard, and maybe being mapped to the max on the vf34. all the orignal work was carried out before i owned the car so previous owner might of asked for it to be mapped like that knowing the pistons wouldnt last.

if i had a 2.5 the i would put a md321t on it but its a 2.0 and the T would be to lagi (in my opion)
im not going to even compare the two turbos, as the md321T is sweet as a nut. how ever the fp green and the md321H are very very similar, apart from the md is a BB cartridge, but only good for 400 but the green is good for 450 if you have the right mods..

iTrader: (20)

Zak at Mocom has done an independent "back to back" test between the MD321T, & FP Green, carried out on his own car.

He has told me that the MD321T spools up between 4-500rpm earlier, and has better throttle response, but both turbos make similar power at the same boost.

I appreciate the MD321T is a few hundred pounds more, but the difference between the turbos is something "you" will appreciate every time you put your foot down !
