TD05 OR 06?
Hi i have a 04 wrx and have been advised to upgrade to a td05 16g as i want to run around 330ish on my standard bottom end, i have seen advertised td06 turbo's for around £150 more than the 05's and was wandering whether to go for one instead as i should get higher bhp at around the same boost pressure, would it be too 'laggy' as its a bigger turbo? what should i do!?!
if i ran the 05 at 1 bar and the 06 at the same the 06 should produce more bhp but would still be the same safe pressure for my standard block is this correct?

hiya there mate depends on what you use your car for really.. if its a daily driven car you should go for td05 18g because its less laggy and has better mid range power output but if you go on the track and race alot you should go for td05 20g because with few good mods and a good mapper you should be getting 400bhp easy with out a problem...

Your only get 400bhp out of a tdo5 20g if your using additives in the fuel mix or the rolling road is broken and it depends on how big the housing is as you get the 7cm one and the 8cm one but 380to 390bhp is more like it but if you got a 2.5 litter you will get 400bhp and yeah if your running a standar bottom end go for the 18g tdo5 or even one of the vf family turbo,s

If your only wanting 330 ish a vf34 or 35 would be a better option. The td 05/16 also good for that power the td06 will be to laggy
Anything more than 330ish and your probably going to wanting a new gearbox in a pretty short time>

the 18g would give you 350bhp with the right mods but if you are on standard internals i would keep to 330 bhp and go with a vf turbo as above mentioned as they do spool up well i love my vf22 back when i was running 320 it was great the 20g will destory your car and gera box as i have just found out, fitting the six speed as we speak

I woulodnt want to run more than 350bhp on a wrx engine, a TD05 16 is as big as you want to go, a 20 running at its full potential will mean your clutch/gearbox and engine are all at risk of dying pretty quickly, so unless you have a nice 6+k lying about to replace them all in one go you will want to keep it nice and reliable (or sell the car and get an STI )

ive got the vf23 turbo on my sti and i have to say it pulls like a beast! i am looking for a bigger turbo though to get my hp to about 400 so will i need the 6 speed gearbox in? what else would i need to change to swap from 5speed to 6speed as i know its not just a straight swap..
just looked at prices for 6 speed gearboxes on ebay... didn't realise they were so expensive.. jeeeeeez!!

If you are aiming for 330 bhp that is available from a TD05 16G, a VF34 or 35 or a TD05 18G providing you have the supporting mods which are :
Efficient decat exhaust system with preferably 3" open neck down pipe. Ported headers and matched uppipe. To go much above 325 bhp and see the true potential of the turbos listed above you will need STi pink injectors which are relatively cheap secondhand but ensure they are OK. Flow tested and cleaned if any doubt.
Personally I would opt fot the 18G which spools as well as the 16 G but moves a lot more air and that turbo with its typical 360 bhp potential would be well on top of your job. New, it also represents fantastic value for money. A TD05-06 20 G for your application is way over the top and would be more expensive, not as good to drive and require bigger injectors.
You need a remap after changing the turbo (or injectors)
If you want to buy an 18G (or 20G for that matter) get in touch and I can provide further information.

Don't shout mate. Low case please.
You don't change fuel rails to fit pink injectors in to an 04 WRX.
Where are you located as we can supplly and fit injectors and turbo at a very good price. You can even supply your own turbo if you wish although ours come ported with oil drain and water pipes ready to fit and our 18Gs perform very well as many people on this board will attest.
The 18G will spool just as well as the 05 16G and is capable of another 20 bhp. It moves a good bit more air and you can achieve the same power at lower boost as you would with the 16G so as far as I am concerned it would be foolish to spend money on a 16G and having it fitted when the cost of an 18G is almost the same.

No secret mate. Unlike another trader, I am not afraid to show my prices as required by Scoobynet's own rules which must only apply to some people. Exhaust inlet ported, oil drain pipe, water pipes, uprated actuator, assembled and ready to fit, £625.
Fitting kit ie. two gaskets £12.50 delivery overnight £12.50.

Standard will not cope if it's standard that is, I would look at a Organic type clutch with an uprated Pressure plate and bearing uncluding spiggot bearing. Something like an Exedy Upgraded (Pink Boxes).
Indeed an 18G will be the better choice here, plus it doesn't have to work as hard to create the same amount of power, remember the 16G will be at its max at those power levels your after and the 18G in its comfort zone. Nice spec on that turbo too Harvey...

Before taking the plunge, remember that you have a standard engine and gearbox.
A gearbox that can cope with the amount either of the turbos is capable of producing will be £2-3k. Thats without even talking about an engine rebuild.
I stripped 2nd gear clean on the road with the 16g.
It's a slippery, but fun slope

Some people are quite hashy and break almost anything given to them. Others with a degree of mechanical sympathy get on fine for a long time with a TY752 five speed box and a TD05-06 20G. Anyone who does regular drag starts and drives their car hard may lack a bit of perception or knowledge if they do not realise that the gearbox may need replacement from time to time.
A number of people are running TY754 boxes in the 400-500 bracket and there are odd ones above that level.
The TY754 boxes operate OK on 400 bhp cars, I know as I have two at 420 and 422 bhp and X923 only ever had a TY 754.
index but now it has a recent Forrester wide ratio box.
The TY 752 as fitted to STi 4 and prior is not as strong as the TY754 and later. An 18G will break a TY752 in time but it could be thousands and thousands of miles. Took me about 20K miles to break one on H13 with a 20G and variously 385-409 bhp.
Martyn Jeffries of Engine Tuner runs a sprint car close to 500 bhp (from memory) on their 206 turbo and he runs a TY754 on the basis that if it breaks he can repair or replace rather than 2.5-3.5k on a fancy box that is unnecessary for normal road use in any case.
Exercise a degree of caution as to who you take advice from on this board. Difficult but necessary if you are not going to waste money or alternatively limit your project.

thanks harvey i see what your saying i used to have a 200sx that was running 470bhp and that was on a standard box that people siad wouldn't cope with 300+!! i just never did any standing starts but did give it a good go most times even track days!, i no things have to give eventually when forces are increased but i dont intend to be doing drag launches or anythin that harsh!! hopefully the wrx should cope with around 350 if driven with some consideration (but not TOO much)

Hope for the best and prepare for worst.
The first thing my Andy.F asked when mapping my car with the 16g was, "are you bothered about the gearbox". The answer was "no" and it was mapped to 1.5bar.
No point being delicate with the transmission, may as well have less power and beat the hell out of it and be quicker IMHO.
TY754 btw.
You may or may not be okay. It would be unwise not to budget for a broken box and suitable replacement though.
