I have a link on its way to me and Uncle Pat will map it (if he ever answers his sodding texts)
Question is: where do I go in the future? The car is a UK MY99 therefore presumably running a TD04 so it will have to work its little socks off to get 300bhp. Im running full decat. panel filter and a Dawes at 1.2bar on WOT in 5th with no det at all, at the mo which gives me 270bhp and 251 ft/lb torque. As the quest for more performance is never ending the link will give me more scope for tuning in the future so whats next? Which turbo? Front entry TD05 or one of the VF series? I'm a little green when it comes to blowers so help is needed in explaining the differences are where they can be sourced from ie which model year came with which turbo and what sort of money they fetch. At present the injecors (440 IIRC) will be staying put and an uprated fuel pump will obviously be needed too. But I need help with the Turbo? Can Mark/Christian/Theo/Adam/Doctor Banks/Harvey/AndyF shed some light please as I know you guys are the oracle Apologies to those guys I missed out
Many thanks in advance(hopefully)

for pure value for money the TD05/06 upgrade is far and away the best.

it has proven it can out perform vf hybrids at twice its price!!!

do UK cars have 440's then, or have you upgraded them?, would be an easy find upgrade for me if they do.

The phase two Uk cars run 440's as std, unfortunately they do not fit phase one rails

Rob

Phase one STI injectors are a straight fit though..

how about phase 1.5 (97/98) ?? 440 ? or 380?

TD05 front entry - if you can source one! talk to Mark @ lateral performance. was very helpful when my TD05 went pop...

Lets run the VF hybrids at 1.6 bar aswell and see how they compare then

john banks

Just one suggestion for a 2.0 litre (haven't tried the Garrett personally):

Up to 260 BHP - TD04
260-320 BHP - VF35
300-350 BHP - TD05 16G (very torquey) or MD304 (good power@1.25 bar)
350-400 BHP - TD05/06 20G hybrid (up to 1.5 bar to avoid surge)
400+ BHP - Garrett/P20 hybrid

Undoubtedly the above turbos will run a larger range than these at lower efficiencies (especially when you consider all the possible dynos) and these are only my opinions, based on conservative power figures. There are issues with some of them as noted which on some cars can narrow their scope.

Many thanks for your help so far gentleman. It would appear that the "best" unit to suit my immediate requirements and those of the future will be the TD05/06.
Which fuel pressure regulator/pump are you chaps using?

Thanks

john banks

I use the FSE reg and Walbro pump from Lateral.

Richard Askew

Thanks John I'll call Mark

Anyone else notice the odd one out there

john banks

Who's the odd one out then?

Adam M

may i declare myself the odd one out there and also suggest that Pat should be up there too, somewhere near the top of the list.

with the possible exception of christian I know a tiny fraction of what the others guys up there know, and would much rather put my car in their hands than my own! Most things I come up with are wrong anyway and born out of a loose grasp of theory, and those things I do get right are normally factual recall of stuff I have had drummed into me by the likes of pat and mark!

I will say, I think John's advice is sound, and would echo the sentiment about calling mark.

dont have any experience of the MHI turbos, but on pats and then morays car the thing has been awesome (only at 1 bar on morays!). Sounds good too! (no dump valve)
