Yes no problem to do this. You can either buy an aftermarket one or get a standard one. You'd just plumb the return in to where it's blanked off at the moment. Is this on the cossie or the scoob? Have a standard pre faclift one in the shed.

leescoobynut

its in my scoob were is it blanked off cause i have a front mount ic not top mount and theres only one hole for the dump valve on the ic pipe which are metal,i take it i will be better off with a recir dv rather than the vta dump valve,as i been reading,i just carnt see how it can be done with a front mount ic,and i only have 1 scoob no cossie might be someone else you are thinking of ,,wish i could have both...

leescoobynut

anyone got any pics who have had it done

The recirc part should still be there also, rear of engine blanked off, fit the recirc valve into the FMIC pipe work then connect to the existing (once blank removed) pipework.

sorry i must have been thinking of a different lee with the cossie. one i was thinking of just swapped his scoob for a cossie.

As speccie says. my explanation was a bit thin on info, sorry.

what year is your scoob? I'm looking for a vta for my 97sti and currently have the recirc. could do a deal

You could also get your pipe ally welded and run without

i have never seen any blanking plate maybe just because ive never looked but will do to see if there is anything like you say ive put a pic up so if someone can point out were im ment to be looking that would help,and yeah if your valve fits mine and mine fits yours then maybe we can sort something out

Follow the dv back to the pipe in the square and the downward connection can be welded shut with a small ally disc. Your DV look horrible, but I guess you know that !

Or just get a plug to put in the pipe. Then you can always put it back on at a later date if you want to Block the vacum hose off as well. A bolt slightly bigger than the diameter of the tub normally does the trick

i had it running with out before and didnt like the noise it sounded funny not like i have herd before when people dont have dv its like a big boooow and the chatter,it just didnt sound right compaired to others is that how its ment to sound with no dump valve

V4JDMSTi

iTrader: (2)

just need to run more boost pressure to get more "chatter" has yours been remapped?

leescoobynut

the dump valve dont look the best but it does make some noise i like it when i bought the car 3 years ago but im starting to think i dont need it and would be better to run recir or nothing its gota be better for engine surely

leescoobynut

i havent had it maped my self but last owner might have i dont know,its just running standard boost 0.9

As mentioned above i've got a standard one in the shed for the early model. Want a deal on the vta? To plum it in you run the pipe from where it is now to the recirc. then out of the other side of the recirc to the off take on the inlet. It's the one with the small bung in just above the group of blue vacum tubing.

Remapping would be yes, FMIC and the induction will be costing you life expectancy on your current lump lol the temporary richness from running the VTA probably eases the lean

V4JDMSTi

Will be running the early ecu though so will adjust itself a certain amount.

leescoobynut

so will this stop the pops and bangs out the back it does run alittle rich cause when i had it in for mot it was showing it was running alittle rich will this bring it down to normal levels, i see what you mean now on how to run the recir valve starting to make sense,is that the best thing to do to have a recir valve rather than run nothing at all,also last owner must of had some sort of remap done cause ive had the car for over 3 years now and aint had no problems with the engine touch wood

leescoobynut

also i dont want it running lean and causing problems if i go down the recir valve root will this happen or will it run better if anything

Should be fine mate, but longevity isn't an accurate measure of being ok. It would be prudent to match your mods to a revised map not only for fuel mix but also the lag !

As a rule, re-circ is the best option and yes it will remove pops and bangs on gear changes, lift off.

Was tongue in cheek mate

leescoobynut

thats good ,if it did start to run lean how would i know of this,also is there anyway of putting some sort of standard air box in with a front mount ic or do i just get a better induction kit cause that came with the car and looks shaby and probley aint the best in the world

leescoobynut

i aint got a clue what sort of deal you would be looking for as i aint got a clue what they are worth mine and yours

leescoobynut

would i need some sort of adapter for it to fit onto the rubber pipe that comes off the ic pipe

53

iTrader: (41)

Standard air box won't fit mate. You could get the air fuel checked by someone with monitor. ESL live is about £595 for a remap which would make the most of your FMIC though.

Mine before and after...(I am running JGM Simtek, so no MAF)

leescoobynut

maf less sounds good as well so are you running no dv

53

iTrader: (41)

Yep !

leescoobynut

what sound does yours make then cause mine just dont sound right it may just be me
