Hi all

well after having my car mapped a few months ago by teamdynamics

Stock turbo and intercooler,uprated fuel pump and turbo back de-cat 3" rough guess from Duncan im at 260 - 270, even though Duncan said it would go a little more but the turbo would be on its limits.

i know i will need bigger turbo, injectors, STI top mount but just how much can i go before its on the edge of going bang.

i know they can go at any time but does any one recommend any figures.

im wanting over 300 - 320 any one got any thoughts on this and can they recommend a turbo suitable for this.



thanks for your time!

Gearbox is the limiting factor... can't cope with much more than 350lbs/ft torque which you'll achieve at a similar BHP figure. If you want more than that, factor in a 6 speed transplant

Re turbo, a VF34 off an STI is the most popular option.

Theres way to add to reliability, i'd uprated the oil pump and FPR before going for a good remap

As above really. I had a Bob Rawle map with decat, Walbro and panel filter on an otherwise standard UK wagon. Achieved 284/317 on the standard td04 But getting the usual "it's running to higher boost" comments from the usual (un)know-it-alls. A good mapper will know what you're engine can take, not some gobsh1te off a car forum

Duncan, like Bob is one of the best around.

Right i will tell them all as im the gob****e,,

HES RUNNING 1.6 BAR OF BOOST ON A STANDARD LUMP WITH A TDO4,. no further comment.

thanks for all your comments, 320bhp would be nice would a VF34 / VF35 do the job?

not sure m8 looks like a dig to me, is it somthing i said LOL

addi monster

iTrader: (6)

no and i appoligise to the op,
OP, after 300 bhp the engine becomes less reliable, im running 352bhp with no issues at the mo, some are not so lucky, its a chance you take when tuning, usually the 330-340bhp mark is the considered the limit ,.

thanks Steve well if 320bhp is what im looking for then its a risk im willing to take

so what turbo will do this job easy, money is a little tight at the moment ;-(

what model is you car, the td05 is a good solid turbo for the classics also the vf 35/34 are a good choice, the td05 turbos can be picked from as little as £50

Was a dig at me as I said my Scoob peaked at an indicated 1.6 bar boost on the td04, but the Lamco boost gauge reads only to 1.3, so indicated. Above gobsh1te seems to insist he knows more than Bob Rawle who mapped the car safely and insisted this boost was fine (normal 1.4-1.5 indicated again).

Apologies to the OP, back onto topic after this unnecessary interlude

you said you car is running 1.6bar, which is way too high,, i cant wait for somone to correct you
you realy are a n0b,. i gave some sound advice to help save the not too distant re build, i hope it goes bang for your petulant replies to some good advice,.

You have 2 ears and one mouth, there is a reason for that. Don't reply me again

YOU ARE WRONG!! your car is running too much boost, btw was that a threat pal?

its a stock bugeye with the following

turbo back de-cat 3"
Walbro fuel pump
K&N Filter
3 Port Boost Solenoid

and also a perrin y peice kit to the intercooler

remap by Duncan


so i was just going to upgrade turbo, injectors and sti top mount

take it easy guys!!!!!!

sorry for the above, sound advice often falls on deaf ears,.
my mate has a vf35 mapped on 95ron pump fuel(normal fuel) with simlar mods(he has a cat back), no need for v power ect and hes making around 325/325

COB 1.6 bar is way too high, but i suppose it's your engine and your wallet. don't suppose you signed a disclaimer for the remap? thought so

i've got
big top mount
decat up pipe (get one from an sti)
3" decat downpipe
vf35 turbo
pink injectors
green panel filter
walbro

remap by race dynamix.

first run on base map was 325bhp , i was happy with that, so it was just tweeked to get mixture spot on. could achive 345-350bhp if i wanted

i've had another remap to run on 95 ron fuel, only lost 7bhp. so 318bhp


getting good reliable power is like a recipe. miss something out and it goes **** up

Adam-M

I totally agree mate spot on, i'd uprate the oil pump before the turbo.

When the engine fails people uprated the pump, so why not uprate it before it fails and could maybe help prevent it.

addi monster

that is very good advice and as you say it seems to be overlooked until it all goes wrong,.

Hi there your engine will last all day long 320-350bhp if has been treated well

As you are said your turbo is on its limit,for 320-350bhp i would go everyday with VF34 or VF35,STi pinks and STi TMIc or FMIC,depends on you

Gearbox will be next,but if you are not looking to launching etc.,you should be OK with this sort of power,but as i said,its just lucky guess/draw..

Depends how your box and engine has been treated

sti pink injectors
sti intercooler
panel filter
decat up pipe
decat or sports cat
walbro pump
decent panel filter
vf35 or vf34 . vf34 works very well on wrx and suits the gearing for everyday road use
not needed but helps 3 port boost solenoid

most important good set of front brembo calipers etc no good going faster if cannot stop just as quick

as for how much it can take is anyones guess some as blow as standard even stis all depends on age/mileage/service/usage history but 320-350 is realistic to run safely within reason.

ok guys thanks for the info, i will start the search for the bits, is there much to fitting the oil pump?

dynamix

iTrader: (3)

Yeah I would go with the std next step upgrade of turbo either td05-16g or vf34 or vf35, a set of sti pink or hawk blue injectors an a sti tmic. These will give you around the 320 mark after the map tweak. As for the gearbox most issues tend to be caused by abuse or driver characteristics so difficult to say whether it will last.

C.o.b - I am confused by what has indicated the boost level on yours but I wouldnt generally map a td04 to that kind of boost as they effectively become flame throwers pushing that hard and reduce power as a result. Boost doesn't always mean more power. Has it been on a proper dyno for those power figures or is that road dyno ? See a lot of road dyno'd cars where they don't make the promised figures on various dynos around the country.

Thanks Duncan, well i will need to you remap it anyway next time your passing sheffield :-)
