hi,anyone know what exactly is involved in fiiting the sti 8 tmic on my 99 uk wagon? ive had a quick look and obviously the mounting brackets will need changing,is it a straight forward fit other than that? do i need a different undertray? does the sti8 tmic actually fit in without having to move anything?any info on this would be excellent as i dont want to take on something to find ive got a nightmare on my hands,i know they do fit but............?

As far as I know, you need to move the clutch fluid res out of the way, but apparently there is a bracket available for this (I also wanted to do the same mod to MY99)

does that mean it needs re-pipeing?

You don't need to move it, you can cut the plastic reservoir to make it shorter.
There is a guide on here, can't think who done it. Maybe check scoobypedia.

cut out the plastic resevior????that sounds a bit odd.

Yep, you can cut it.

Plenty of decent guides on here about fitting a STi TMIC

yep.take the clutch res of and cut the bottom off!
their is also a bracket in the middle of the bulkhead under the intercooler,i had to tap the sides slightly to stop the sti intercooler hard pipes knocking under acceleration!
also on mine i had to make little brackets to sit the coil pack further forward because i wanted to keep my dump valve!
and a samco 'y' hose is alot easier to fit on to the turbo as its softer!

sounds alot but wasnt really,and looks good when its done!!

so,im assuming the my99 recirc dump valve dosent fit?what about undertray?

Floyd

Check my project thread... All you need to know. Or buy my big Alloy TMIC and fit with no hassles...

99greenwagon

iTrader: (39)

i did consider your tmic but opted for an sti8,recieved it today and just loooking for tips/advice before i attempt to fit,will it affect the ecutek remap i have?

Floyd

iTrader: (9)

Yes. New remap required. The STi8 conversion is a good one too but a lot of work. Good luck.

not sure wether to take the fitting on now?

99gw, have you got an aversion to FMICs? An all round better solution IMO - and 'frees' you up for large bhp later should you want it, due to the massively reduced ACTs... And, of course, not forgetting those all-important spark plugs <groan>

99greenwagon

iTrader: (39)

i dont want to change the turbo,i like the vf35 and just wanted to go from 300 to about 340 ish,so i think the sti8 tmic will be fine,my plugs are ok at the moment..just scared of trying to fit it now

99greenwagon

iTrader: (39)

oh and also cant afford to pay out a whole days labour for fitting fmic!

99greenwagon

iTrader: (39)

do i need the sti recirc dump valve aswell?

joz8968

iTrader: (13)

Oh in that case then yeah, the v.8 TM will be fine.

So long as your ISCV isn't in the way, then there's no reason why you can't use the OEM v.8's flanged recirc DV too. You'll just have get suitable lengths of flexi silicone hose/s (and possible ally reducers) to be able to fashion a return 'hose' from DV to your turbo intake elbow's recirc port, etc...

99greenwagon

iTrader: (39)

hmmmm,ok,so whats the normal procedure for the undertray,this all sounds a bit technical!

joz8968

iTrader: (13)

Well, I expect you'll have to use the STi 8's own undertray, to ensure the air gets directed to the STi TM properly. Prob take a bit of fettling to get it to fit properly, but if you're handy with a spanner, tin snips, etc...

Just realised: it prob will be the MY99's offset coilpack that might be an issue in fouling the STi 8 DV ....

danny c

iTrader: (6)

yea i had that issue!i just made little plates and sat it a bit further forward!

Or get one of these:-

http://cgi.ebay.co.uk/IMPREZA-Zero-S...item19b7db523c

Directs air over the front of the IC, as well as the rear - for lower ACT's.

im surprised i havent seen u about,u r from my neck of the woods!
thanks joz,probably go for an sti8 undertray.i didnt realise that when u buy an sti8 tmic u have to spend a load more to fit it same old i spose!

joz8968

iTrader: (13)

Yeah, that's why, when you factor in labour/hassle, etc., there's not much more hassle in installing a (quality) FM!

But people have their own personal reasons for still wanting a TM e.g. capped power output, OEM look, throttle response (moot point), cost savings, etc...

does anyone know wether the my99 oe dump valve is useable with sti 8 tmic or does it not fit at all?

Here is some food for thought.

yeah but i already have the sti top mount and the guide that bob 5 posted up earlier dosent look to much bother really. im happy that im going tmic as i like the oe front end,and i dont want to take my stock uk block and gearbox over 350/350.there are genuine good reasons for why i chose to go tmic and just trying to gather as much info as possible and to make sure when i do the job that i have all the parts required to finish the installation as need car all the time. but i can see your point to a degree

Your 1999 oe dump valve won fit mate, dispite both valves being held on with 2 bolts , the hole in the intercooler are offset.
