how to know is it STI engine
 

hi every forum member i am new in subaru so want ask u all some Qustion!!!
I bought a ver 3 wrx last week!!! And the previous owner say he already change the engine to STI. from the hood i saw the red intake manifold the meter show the word sti with some long dot dot light between the speedo meter and rpm the first dot got a lock word (wht's that??)!!! Beside tht how i can know is it STI engine.

Subaru Impreza FAQ
May help but if just engine may not?

I'm not exactly sure that the internal dials should tell the tail of the STi engine.Did the guy you bought it off have any paper work outlining the transplant say for insurance reasons? The engine should have other visual aids,like the rad cap.Does the engine have any plates on it that you could check with the DMV? I'm sure the other lads on here will have more ideas and advice bout this dude.... :thumb:

thanks for the info bro !!! actually what the meaning of DMV??

thanks for the info bro!!!

Database of motor vehicles i think...Its like a government thing where you can get info on cars,any finance owed,was it crashed,was it stolen...

The dot dot and lock thing you mentioned, is the DCCD lights on the dash.

do you have the switch in the centre console too? (for the diff)

another thing is, what turbo is fitted? is it the STI one?

ohh ic !!! wht is the use of DCCD ??

wht is the size of sti turbo?? i saw the word IHI and i dun have the DCCD switch!! Can i know the engine spec or model based on the ECU ?? Is there any other thing tht i can verify from my engine or others??

IHI is an STI turbo (various ones fitted depending on model year), all the WRX's have an MHI, you won't have DCCD as thats part of the gearbox and I assume he only changed the engine. ECU is probably no help as he probably kept the WRX one and has had it 'chipped'

Simon

assumption is the mother of all f**k ups :thumb:

to the lights change when you move the wheel? can you feel the difference when you move the switch? when on LOCK, and moving slowly like parking, do you get strange noises?


If they have changed the ECU which is likely if they have done all the other work, then lift back the carpet, remove the plate and find out what is on the cover.

If it has an IHI turbo, it is likely to be an STI 3 on car, of which the 3 + 4 can't be chipped.

any chance of taking pictures and posting them up?

ohh ic thanks for helping bro!!!
is it wrx ecu same with sti??
if i open up the ecu to see will i knw is it the ecu being rechipped b4??

i already saw the ecu it stated 6s with alot of num!!!!
i will post some pic up next week thanks for helping cheersss
there is no dccd around my handbrake there!!!!

the 6s is the sti 3 ecu

i have exactly the same thing going on with my 96 wrx , there is no paper work to prove it but it have the red inlet manifold, yellow injectors, IHI turbo, 6s ecu etc

i was told the only way to know for sure is to take the pistons out

A partial engine strip would be the only way to tell 100% if it is a true STi engine,unless you have access to an Endoscope to look inside the engine.
Cylinder Head Codes are LHB and RHB.
Valve Codes are EH and IH.
It will have Inner(under Bucket)Shims
Camshaft Codes RH4,LH4 Inlet and Exhaust.
Pistons are Forged and will have HF2/3 on the underside of the Crown.

yes i have the same thing with u bro so is sti and sti ra the same??

nice info bro!!!! is it all the same from sti ver 2 to ver 6??

Nope, that's just V3 and possibly V4.

and even then, there will be some differences car to car.

ohhh!! how about the sti with type ra is it the ecu code and part same???

Mine was different to what was posted for the STI V3/V4 as mine is a phase 1 V2 RA. ECU has 4 plugs on it and a 'chip' in it from STI which can be re-mapped. ECU code was SB, IIRC, can't say about later RA's as I haven't had one sorry.

hi, sorry for hi-jacking but i have a 96 sti import but i don't have a switch in the centre of my console:confused: as any body got a pic of where abouts this switch is located,

Not all STI's have DCCD, was'nt it mainly the RA'S that had this?

i already take some photo but i dunno how to post it up help!!!!
i'm really noobs lol
is it if my speed cable spoiled it will hv rev cut while i driving the car??
