If you are just talking about the TD05 itself on the engine probably about 340bhp max. But this is assuming you have the breathing/cooling/fuelling all accounted for.

BTW i have a modded sti2 so i know how much money you need to get there!

With my 90 degree entry ( 2nd hand! ) TD05 on my MY94 wagon, STiV TMIC, 550 injectors, fuel pump and regulator, headers, decat exhaust, Samco hoses, air filter, heat mods, electronic boost controller, Power FC/remap then 363/325, slipping too on rollers.
Not sure just what the TD05 will really do at its max, but it runs upto my mapping limits at 24 PSI quite well!

have your replaced your gearbox yet?

Nope, standard internals, std gearbox etc. Maybe I am mechanically sensitive (lol).
Only a couple of months since mapped, and to be honest I use the lower boost setting at 18 psi ( around 320 bhp .. dunno torque ) for pottering about, as the car goes to/from work, shopping etc.
Is it 1.65 bar? Wow, I work in PSi ... 29 psi is 2 bar ... but I know I can't run it that far!! Already off the MAP and MAF sensors... for pressure and air flow, need 3 bar MAP sensor and 300ZX MAF sensor, and a remap for any more improvements... and then I'd want a TD0/06 20G turbo and maybe a FMIC ... but what power!
Go for it Rupert, increase the boost with supporting mods and break the 300 barrier! But look at the fueling (pump and regulator), ( get gauges if not got already for knock and AFR ), fuel cut defender, electronic boost control and ported headers.
Just my 2p th.

Actually, I would love an STi bottom end, forged pistons, steel rods, 8000 RPM limit Hmmmm
I like a high reving motor... if/when she pops then a trip to APi is due for a good bottom end ... !

Vulnax, are you running a wrx botoom end then?
ie, same as UK?
Im hovering about 320/30 but have just switched to a 3" decat and am about to fit 550's and GT spec headers
interested in your 300zx MAF theory, will it go into phase2's?
was going to go for a custom tmic over my stiV i/c but might hold back on that now!
good figures

About 350hp is the sensible limit. With "differenct" rolling roads this may be as high as 370hp. However with the use of dangeroud boost levels, you can probably squeeze another 10-15hp.

I also have many supporting mods, headers, 550's, fuel pump & reg, decat exhaust, bigger TMIC etc. and it was mapped at 24 psi on the PFC, which makes it safe (ish?) regards det and AFR levels.
I am told the 300 zx MAF fits th escooby, although remap/reclibration of the MAF readings in the ECU are needed; not sure what a 3 bar MAP sensor needs.
I get the boost via an electronic boost controller. Std TD05 holding up well !

So I tried as much as she would take and mapped to that! ( no I didn't map it!! ).
The STi should take at least as much as a WRX bottom end ( likely more safely ) if all the other mods are in place and is MAPPED for it ..but just wind up the boost and unless fuel cut stops you you will do damage IMHO.
Defo need a mappable ECU, more fueling, good cooling ( air ) etc.
As Paul says, silly levels slightly help but would cause more problems - air gets hotter, and you reach limits of things like gaskets with the higher pressures, and and weak air/fuel - melt pistons, det and break pistons or bottom end I guess.

There is no such thing as a set level of boost you would call dangerous, it will vary from car to car. The mapper can tell how much stress he is putting on the engine from the data obtained from the laptop, boost is only one of many parameters determining engine stress levels.
For example 1.2 bar at 6000 rpm could be dangerous on a TD04 due mainly to the high exhaust backpressure generated, this would be obvious to the mapper primarily via the ignition timing requirements and wastegate duty cycle. The flip side would be the free breathing engines of Stevebt and Vulnax which are safely mapped to run at 1.6 bar+
Andy
ps Coulty, yours was only mapped to 1.4 bar to save the gearbox
maybe should have made that 1.3

There is a bit more torque available there Stuart but the map sensor rating on the Microtech would be an issue. They do an upgraded sensor I believe which would also solve the overboost CEL issue.

A straight, silver STI TMIC, I believe off a STI V, but modded to suit the early classic - ally pipes cut and welded, new brackets to mount, blank off TMIC's dump valve hole as car has other route to original ( well, oem position but forge recirc dump valve ) , shorten throttle body inlet & TMIC outlet, samco hoses modded etc. Also with the bonnet vent under plate to suit new TMIC. ( Quite important if you want the air to go the right way! ).
Bit expensive, but way less than an APS or MRT item, and seems to work well.
Remember, I started with a slanty little black TMIC!
