hi, i start it with (never) finished work... :D

more details to follow... :)

Here we are, components: Subaru TD04L Sturovo manifold & downpipe Reverant EMS2 Supra injectors Variable TPS PLX DM-6 with WB and Boost modules Intercooler Rec BOV Carbon air filter DIY coolant reroute Mocal oil radiator wiht thermo-sandwich 1.8 flywheel & Exedy Stage1 (to be installed)
EBC (tbi)

Sounds pretty good man! Congrats. I'm digging the setup, any more details on the mani/downpipe? IIRC i saw sturovo's thread at one point, is he making setups now?

Yes he's doing now, ask him for info... ;)

Looks great! I'll be making a similar heat shield for my setup.

Wow Giuseppe, that looks fantastic! You have a great eye for details, well done :vash2:

I particularly like shiny heat shields and in this shot we also get see how clean and tidy the engine bay is.
It is hard to imagine this car is more than 20 years old. :)

Nice pics dude, we are neighbours, I'm from Spain.

Have you taken it to the dyno? HP?

nope, it's still in progress, 1.8 fly wheel with exedy s1, EBC with hi/low switch and some fine tuning...

lower at 7psi, higher at 12psi, bumps are from an interference on ms2 now resolved...
at hi boost the limit is the stock 1,75" exhaust

Good lord man, get a bigger exhaust! That is some seriously late spool from a td04

maybe also a leaking bov? i got this one wornkig on recirculating config

back with a little trouble, i am using a recirc bov like that one above,

but even at lower spring rate and setting, when over 8/9 psi turbo goes surge (or maybe flutter?) on off-throttle...

solution? get a sequential bov? hks or some cheaper (!) but good copy?

That's not unusual.

Where is the signal line connected? And is the bov before or after the intercooler?

Signal line is just after the TB and the BOV is after the IC

here the sound

Yes that is more prominent than I would have expected at your low boost levels. Could you take a picture of the blow off valve as it is mounted currently? Where are you recirculating to?
