I've just got a new job and have been thinking of changing my car( MY03 WRX with tek 3 and Blitz NUR Spec R).

I then thought going for a 2.5 litre engine may be an idea. Can anyone give me an indication of costs for all the things that are required?

Thanks,

Graham

don't forget the extra insurance costs on top of the hardware....

£1500 short engine
£200 injectors?
£125 fuel pump
£180 SX reg
£300 STI8 TMIC
£300 samco hoses
£300 - £800 decent turbo
£150 - £500 exhaust manifold (ported oe - aftermarket)
£500+ fitting and gaskets
£100 panel filter, oil, oil filter
£200 for exhaust wrap fluids and other stuff
£650 re map
£1500 for the relacement gearbox you're going to bust
£300+ gauges, knocklink, afr
£500 bigger brakes

Cheap isn't it

F
£500 better suspension

If I am going to go down this route, am I best to get it all done by a company? I'd source the bits myself as it'd be cheaper. Also, should I be looking at buying a 6 speed box from a Sti? and what turbo is recommended?

Jamesemt

IMHO you are far better off going to one company, who can do you a drive in/drive out job. That way if you do have any problems, it just goes back to one place...

Also don't forget insurance as previously stated - depending how old you are, it could get very silly very quickly.

Floyd's prices IMO are a bit steep Don't Xtreme Scoobies do a package for £2,500??

I always thought 5 speed gearboxes were limited (tuning wise) by the torque...and as a 2.5 conversion is all about torque, I think a 6 speed would be a wise investment

Don't think Floyd's prices are that high, but I've put a * by what you could remove if you already had a GDB STi with fuel pump, exhaust, ECU:

£1500 short engine
*£200 injectors?
*£125 fuel pump
*£180 SX reg
*£300 STI8 TMIC
*£300 samco hoses
£300 - £800 decent turbo
£150 - £500 exhaust manifold (ported oe - aftermarket)
£500+ fitting and gaskets
£100 panel filter, oil, oil filter
£200 for exhaust wrap fluids and other stuff
* less to reflash an existing remap, £650 re map
*£1500 for the relacement gearbox you're going to bust
£300+ gauges, knocklink, afr
*£500 bigger brakes


Changes things rather... for £2500 on a non-STI there is a lot of work to do to get the most out it.

G4RUD

Any other companies I should take a look at so I can compare prices, etc?

Have many people with a WRX gone down the route of going to a 2.5 litre or is it a bit o.t.t?

Cheers,

Graham

Dont think its ott. Mine is my first scoob so ive not had the experience of going from a 2L to a 2.5L but having had a shot of friends 2L scooby, i found the 2.5 has a lot better low down pull. Less gearchanges and a big kick up the a*se if you plant the pedal! Scoobyclinic did mine and had no problems with it.

Regards,
Doug.

Not on the radar but curious to see how this would compare with swapping a stock V5 STi classic - stil around the £2,500 mark?

G4RUD

Can you tell me the total cost of the job?(PM me if you want) How long did it take?

Thanks, Graham

G4RUD

can anyone who has had a 2.5 build done on their WRX by a company tell me how much they paid?

Thanks,

Graham

I think this question needs some boundries.
If it is a swap of short blocks only (because the 2 litre is knackered) then the cost will be quite cheap as a rebuild.
If the goal is a 400 x 400 engine then the costs above seem right and the labour will rocket.
If the goal is, say, 500 x 480 then.....

Remember the gearbox in all this.

6 speeder = £2000
5 speed ppg = £2250 plus fitting.

Makes the litchfield Type 25 a viable bargain, and buying a 2.5 already done THE way to go 2.5?

Graham

G4RUD

I'm trying to get an idea of whether or not to stick with the 2l and mod it or to go for the 2.5l and keep things sensible, i.e. not going for 500 x 480. I want reliability and value for money. I expect if the build is done properly and I don't try to get silly performance then reliability is okay, value for money is always open to debate.

I would guess that you can get a nice engine by simply using the 2.5 and some simple mods to 'balance' things.
Try talking to AndyF. (or David at www.apiengines.com)

I have an uprated US EJ25 engine for sale done under 2000miles for sale if interested pm or email me.

I am with John on this, if you have an already modded 2.0L then cost is really only the 2.5L short engine and fitting / gaskets etc. as other bits in place for a good say 400 bhp/lbft motor.
As John "*"'d below, I have all those and also tubular headers, Apex'I ECU, boost controller, bigger injectors, STiV TMIC, samco air and water hoses, usual gauges, fuel pump and regulator, induction mods, TD05 turbo ( but runs 360 bhp at moment! ), and as already mapped a remap is far cheaper on the Apexi PFC .. so what, £900 - £1500 for a 2.5l motor, ££200 gaskets, £500 labour ... and assuming gearbox lasts, not much over £2000 all done!

Now if it's to a bog std car then as 911 says, go for a little stressed motor with little extras and lower costs, or pay MORE and get the above list fitted and more power / torque!

Who will fit it for £500 !!

G4RUD

After some discussion with ChristianR he thinks that I should initially go for a set up like this: td05 front entry turbo, induction system, uprated fuel pump and of course a remap. Then if I want more power, I could easily change the turbo to another one, run more boost, upgrade the injectors and also the i/c.

Where is the best/ cheapest place to buy the turbo, fuel pump and injectors? I'm going to get a Roger Clark 80mm induction kit.

Thanks,

Graham

Ring around, try ASPerformance, XTreme Scoobies, Revolution or the other companies who advertise on the ScoobynetShop or in the scooby mags.

Well, £500 would be about 2 days labour ( outside of a Subaru dealer anyway!! ) and since it would be say 2-3 hours to remove old engine, an hour or 2 to remove parts to reuse ( alternator, pullies perhaps, oil pump, flywheel aned clutch, heads, injectors, manifold, fuel rails, reservoirs etc. ), a couple of hours to assemble parts on new block, and 2 - 3 hours to replace engine, should / could be all done in 2 days.

Assumes no work done on heads or headers during tghis time of course!

Well, seemed about right to me and from others posts here ... bet TweenieRob could do it in a day!!!

SCOOBYD00

Digging this one up... what internals (if any are reused from the donor engine) i.e. I have an STi, the stock 2.5 Piston are not forged - do you not have to shell out for new pistons / con rods.. rings... etc ?

From what I've read it seems its a bottom end swapout retaining my head?

Sorry - bit slow

I reckon he can, but given the right circumstances, Wallis, and Darley can do it overnight

If your only after 350-400bhp you would be better off going for something like the T25 or getting a JDM STi and seeing what larger twin srcoll turbos are available to you, 2.5 isnt going to do you much good if you only want a little over 300bhp.

Does the 2.5 use the hyper reuetic (sp) pistons then?
Thought it was only the JDM twin scrolls that used these.

If thinks thats a bit of a big assumption for a 400x400 motor

Decent gearbox add £2000-2500+

LOL, well they've had practice ( and this year helpers as usual!! )

So would it be of any great benefit to change the bottom end of my 02WRX for the 2.5, only lightly modded at the mo?
