As you can see from my other thread, I have managed to kill the engine in my 2002 bugeye WRX (UK spec)

I can source a low mileage used bugeye STi engine but getting mixed info as to whether it is a straightforward swap.

I have a VF35 and STi pinks to fit anyway, my top mount I/C is larger than the standard STi one.

I would have to use my flywheel and clutch to mate up with my 5 speed box.

Can someone who has actually done this give me a straight answer please before I spend a chunk of money ?

 

legacy twin turbo engine

 

Sounds like hard work !

 

It depends on the state of your heads, if you block the oil feeds to the AVCS on the STI block, and fit your heads, then it should be easy.

Problems start with the engine loom that controls the AVCS, plus the ecu....

IMHO

dunx

P.S. I think the six speed clutch/flywheel fits, but you need to check clearance in the bell-housing, and maybe fettle to suit.

 

Thanks for that, so I have had duff info about the WRX having AVCS then !

I was trying to avoid changing the heads etc, just wanted as close as possible to engine straight out, replacement straight in (within reason of course !)

 

You could ask a friendly mapper... as to the effect of non-active AVCS. I would imagine it will be fine on a road car.

I have seen a thread somewhere on one of the US forums about running with the AVCS disabled, apparantly has some effect on low end response ?

Simon says not worth the hassle of getting the STi lump into the car, tomorrow I will be getting some prices together for a used WRX engine and deciding which way to proceed.

 

I read on another forum that the sti lump and ecu can be used but you need to add a few wires into the wrx loom to connect the avcs. Depends on how good the price is on the sti lump and how good you are with electrics, as if you have to pay someone else to do it could be expensive, The sti clutch and flywheel can be used, but the bell housing needs modifying to get clearance, there is a post somewhere showing the amount of cutting required, you may need a six speed starter motor as well though.

 

I may use the STi short motor with the WRX heads, problem solved ?

 

I think that may be the easiest solution. You then end up with a much stronger engine that works with your existing ecu.

 

High Five !!!!!!!!!!!!!!!!!!!!!!!

 

 

LOL

 

LMFAO!!!!

 

Do block the oil feeds for the AVCS won't you fella !

LOL

dunx

 

In a complete U-turn worthy of a politician, I have (hopefully !) sourced a std spec recon WRX engine.

I have a VF35, STi pinks, uprated fuel pump, iridium plugs and 3 port solenoid to go on when the engine is fitted and hopefully Simon can do the honours and map it so that I can run it in !

 

if you are able to get the complete sti motor n loom i would suggest wiring it up definitely worth rather than combining parts. it may be expensive now but worth it in the long run

 

found this if it helps SUBARU ENGINES
get a complete jdm v7 engine for $1999, converts to bout a grand here

 

Cheers for that, should have my recon WRX motor on Monday !

 

What have you gone for in the end?

 

Just a standard recon WRX engine, I will post more details when it has arrived and i have checked it over.

I was very tempted by the 2.1 forged build for £2450 including a CDB, the only problem was that I would have the labour cost to remove my engine, swap the heads etc and then the cost of putting it all back together (even the cost of head gaskets etc start to mount up)

If the recon engine proves to be 'too good to be true', I may still look at this option.

The people due to fit the engine have p***ed me off somewhat though.

This mornings phone call went along the lines of 'oh, it's a recon engine we're swapping ? it will be more than we originally quoted, we thought that you were getting a second hand engine ?'

Even if it had been a second hand engine, not many people sell them with all the ancillaries attached (turbo, alternator etc) !

To save a few quid, I fitted the uprated fuel pump myself today, every little helps !

 

whos recond the engine?

 

It's a secret !

Well, it is until I have received it and had chance to look it over.

If everything is as described I may have a cheap source for fellow Scoobynetters !

or alternatively if not, a fantastic new thread about legal action !
