Sick of the LAG from my FMIC
I bought my 1998 UK Turbo 2000 Terzo back in July,
From what i could see the only modifacation to the engine department was a Japspeed fmic, after driving it home i found that the turbo (td04) was shagged or at least on its way out because it was only producing 0.6 bar of boost.
So, i swapped out the Turbo for a Td05 16g, fitted a 3" turbo back decat system with bellmouth downpipe, walbro 255, fuel pressure regulator, a set of NGK's and magnecor leads and a piper X filter, had an ELS board fitted and had it mapped to run mafless.
I was so chuffed with the results (running about 320bhp) pulls like a steriod fuelled train from about 2900rpm all the way round to 6800 in all gears.
So, here's my problem/Question:
Im sick of the turbo Lag and the lazy wait for the power to begin....lol
Whats the most efficient upgraded Tmic i can fit without doing any modifications or at least minimul modification?
cheers

You don't say how much boost the 20g is making, or when it makes 1 bar.
It's not simply a question of saying that one component is responsible for the lag. Sometimes you can help matters by being in the right gear for the mod combination you have to work properly.
Regardless of what else is said plenty of JS front mounts are producing good numbers at the right rpm, so you might want to do a little more investigation before you throw the baby out with the bath water.

It's not a 20g, its a 16g and it runs 1.2 bar.
Im not saying theres a problem with the combination, it all works very well, what i am saying is that i would like to change to a Top mount for reduced lag and increased 0-60 times.
dont get me wrong, the power gets laid down very well and is great all the way through apart from standing start.

Its never an issue once she's up and off the mark and spooling away, i spend most of my time up and down the box, just getting dissapointed with being slow of the start, and i dont fancy blowin the clutch or gearbox!
although i was planning on fitting an type RA box in march next year.

Yep, between a rock and a hard place. Need to launch harder but may pay the price of a gearbox.
Changing back to a top mount will not improve your S/S performance. You need to get the engine turning above the peak torque rpm before you engage the clutch otherwise it will just bog down.

I think it's the response more than lag, sometimes incorrectly fitted pipe work on fmic can cause this. not saying that all fmic are not responsive.

The cooler you have is not efficient, don't know why so many people fit them (aside from cheap bling). If you're serious about performance fit a decent FMIC (HDi GT2) or a Newage STi TMIC.
My UK Turbo 2000 with a STi TMIC + TD05/16g went like the clappers at 1.5bar.
