Anybody know the differences between the two and also any pics please (exterior, interior and engine bays)

Paul.

 

View my Scooby that’s a V3
The V3 runs a VF28 Turbo the V4 a VF29.
Both have the facelift front end but the V4 has the newer style dash with the cubby hole in the top.

 

as posted here exactly, ive also got a V3 that was MENT to be a V4

dash is the only thing ive noticed on mine to look at

 

The V3 actually runs a VF23 theV4 has a VF24 and V5 VF28

 

The sti 3 has the larger VF23 turbo and wilder cams compared to the v4 that has a VF24. However the v4 has the updated dash, which looks nicer than the v3

OOPS am crap with numbers
I knew they where one number apart red wines fault.
The 22B has the VF23 too I think

 

yes the 22b has the vf23

but the v3 wrx has a vf22

 

Whats the going rate on the two models? Had a look at a V3 with 48k miles, imported last Dec'07 and is mechanically sound although left side of car has had a respray (might of had some serious scratches) but all the panels look original.

Anyway i might be able to get it for about £3200 if he's desprite to sell.

That sounds about right for an average V3 pay a bit more for a mint one they are going for nothing now buyers market
Dont worry if it knocks a little when cold (piston slap) most V3-V4s do it just make sure its not there when warm.

 

more of a tick than a knock

 

its deffo a knock !!!

 

Agree its very off putting at first if I didn't know better would think it was knackered. Mine doesn't do it at all when the weather is hot but even when cold goes off after 2 or 3 miles.

 

I went to look at a white V4 STi fresh import and totally standard. The car had done 56K or 90Km's up for £3895. But it needed a remap for uk fuel, service, some body work done, a new interior etc... and the guy selling it who was 19 and could not get insurance when he currently owns a JDM Integra Type R

I did not go for it in the end, the deal just seemed dodgy somehow

 

Can you remap the V3/4 STI ECU’s?
I believe the fuelling is not so bad as the really high octane fuel was not available until 1998 think it was

 

no ul need an after market ecu apexi. sim teck haltec hks fcon but i would say go for the apexi pfc as its the most common and cheapest

 

I ran mine on Optimax + Millers for 40k miles without any problems.

 

mines in the for sale section

V3, little bit higher price but does have alot of goodies on it

 

i paied 4500 for mine in april this year, knocks when cold but shuts up after, some days is worse than others as said though

my tappets are the worst thing though

 

mine ticks when it starts cold then goes, wonder what it is then

 

you aint got piston slap OR you dont know the difference

my tappets tick, when cold my car knocks

 

I think the likes of Polar Performance and Jolly Green Monster might take issue with you there... it used to be the case that the older ECUs weren't mappable, but not any more.

 

seem to be from right hand side of the engine when under the hood and then it goes.....deff a tappet type sound

 

I maybe in a minority but i actually prefer the pre-facelift dash..

There are bargains out there to be had, Ive just bought a V3 STI RA, fresh import with 50k on the clock, since its been in the country the guy spent a few quid on it...Simtek ecu, new tyres, turbo back afterburner exhaust and a few other bits and pieces all for 4k.

 

sounds like tappets then, maybe the rockercover is leaking ( like mine pmsl)

 

i couldnt find anyone that mapped them at the time and after going on scooby net and researched and spoke to a few tuners i ended up going for for PFC. i never knew about jolly green monster then and as for polar performance ive never heard of them and i dont think il be rushing to find there number. there u go ive learnt something new TODAY V3 AND V4 CAN BE MAPPED THANK U

 

Actually I just checked, looks like it might still just be the earlier (up to '96) ones that can now be mapped... best check if you're unsure

 

i had a feeking i was rite but just wasnt sure.so i think PFC is ur best option.

 

Think you will find that the 22b has a vf22 turbo.

 

iirc 100 22b's did come with the vf23 Chris

you're right! the vf22 was an optional turbo for the 22b. you learn something new everyday!
