Previously owned an STI 8 which I thought was a fantastic car. I sold it and bought a High powered Evo 6.

I found that the Evo was a superior car out of the box in its handling abilities. It could be chucked about and gave allot more driver feedback than the Impreza.

I have since sold the Evo as the running costs involved were just silly. 4k+ per year not including insurance/ tires or brakes.

I have always loved the look of a 3 door impreza and I set on getting one but I have concerns about engine reliability. Most I have found have anywhere between 40k to 70k miles and an engine rebuild in its history.

Is there something about these engines that fails? I see the oil pump cropping up allot?

Are the differences between the V4/5/6 only cosmetic? engine wise is everything the same?

How about the handling characteristics between these models?

I refer earlier about the Version 8 STI not being as good out of the box as the Evo, how does the type r feel in comparison to an Evo 6?

thanks

 

LOL.... would you believe the irony in this...

I just recieved an email from a lad local to me about his type R, its a 97 version 4. He has it advertised on Pistonheads so i contacted him for an inspection and test drive. (I was told i could get this car for about 6k)

He just replied to my email saying a piston has let go...

I am even more interested in that car now as i could through in a version 8 engine... will it fit??? or a 2.5 from Mr Forrest.

 

No such thing as a 3 door impreza - 2 door (plus boot), 4 and 5 door only. 3 door is a hatchback like a focus.

2.5 from Andy in a lighter classic shell would fly - go for it https://www.scoobynet.com/group-buys...uy-1095-a.html

stiIV type r is the last pre facelift so it has the older interior like the 22B. RCM modified oil pump is a recommended safeguard. Handling much more like evo 6 and performance as standard on a par. With a 2.5 at say 450/450 it'd be about as fast as anyone would want on the road ( e.g. better power to weight ratio than 997 twin turbo!)

 

Interesting, I have an RA on a 95, how much would this 2.5 conversion be for my car, would it work with the centre diff ok etc, can anyone shed some light on this conversion as Im interested?

 

Short motor £1500, turbo £850, ECU + mapping £795, injectors £350, Clutch £400+, Engine gasket kit £100, fitting depends.. its free for me as mate owns garage and i'm more than capable.... thats 4k already without labour costs and it will be far from 450/450.

back on topic now please.

 

Bump...

anyone have answers/coments/views on this?

 

STi 4 has the same updated dash as the 5 and 6 the v3 had the older dash

 

A V5 with a 321H is a very rapid car. no need to go the 2.5 way. the gearbox is upto the job too.

 

have a look at my spec,API have done all the work to it except the suspension.If you're looking for a type r look for one that has had the engine work done already by a reputable builder,no problem then.

 

oops - you're right - cheers

 

Thanks for the replies folks.

Is the oil pump an issue on these engines.?

Which versions suffer from MAF sensor problems?

 

If you look after it and change the oil often, then you should be fine. As long as you take a bit of care to warm up and cool down.

 

are all 3 versions fitted with the same turbo?

 

up for some more responce

 

V5 and V6 had the weak MAFs

 

mines a 97 and its actually a version 3 and a half as in it has a v3 bumper and a v4 donnet sti 4 engine i was told that because its an sti they were always a year ahead but some of the first ones off the production line get a bit of a mix and match..

 

The v3/4 have no physical difference on the outside only the dash is different on the inside. The version 4 has a vf24 turbo and the version 3 has a vf23 turbo, the cams on version are a bit better.

Banny

 

What differencies does the V/6 type R's have over the versions 3,4,5 type R's engine internals.
I now about the longer fith gear and slight other differencies.
