can anyone help i have a vf 23 to go on my 1998 uk turbo,idealy i know it needs a new ecu and re-map but justncant afford the £700-£1000 it will cost,can i put it on without a re-map. i know it wont work too its full poitential but its doing my head in sat in the garage thanks shaun

 

the simple answer is no. if you install it without a remap & drive it hard you will kill your engine.

On the other hand you could install it & drive very carefully off boost, but then what is the point in that?

Wait till you can afford the remap.

 

TBH i think your better off leaving it in the garage until your ready to map. I know what you mean about being eager, but the fact is you will get more boost and performance out of your current setup than you will out of a non-mapped VF23.

Best things come to those people who wait.

Good Luck

 

thanks for the info chaps kind of knew i would just have to wait but i think it will be worth the wait, current mods are a full hks de-cat system,hks super power flow,fmic and dawes device set at 1bar... so hope with the vf on and a re-mao il break the 300 mark

 

i got basically same mods mate. i think u will look around that mark but i suggest an uprated fuel pump to mate. mine is a 99 with kakumie headers, full decat system, uk300 tmic, k an n induction kit, vf23 also an walbro fuel pump then remap so hoping to get over 300bhp i hope

 

i was running a rb5 (my99 uk eng) with a -
fmic
vf23
full decat
piper induction
EcuTEK remap
produced - 326bhp 315lb ft with a slipping clutch

now got a v4 sti bottom end and ported headers and am looking to tweak ecu...

basically i did fit my vf23 and fmic with my decat without a remap... drove fine for couple months... i didnt touch the boost and pulled very well anyway, but i didnt drive hard till remap..

keep it in garage till mapped mate

 

alright mate so with mine u think i keep all my parts off mainly vf23 till i get remap. i mean if i fit it obviously wont boost till remap but was your engine reliable still an how long u have the vf on until u had remap

 

think i was running for about 8 weeks but i never drove hard and it was fine...

boost pressure will increase or atleast mine did and i never increased it...

if your planning on getting the map soonish then why not fit it...??

map should only cost in the region of £500-650, depending where your based, i used Pat herborn or try Jolly green monster..
