newbie evo 8 owner wants upgrades ;)

[andyw08]

Hi all, new to owning an evo.....wanted one for years but could never afford one! But eventually i got there ha ha
anyway im after doin a few upgrades to make it faster! its a 55 plate evo 8 gsr 260. Previous owner "told" me (no printout) that it was running roughly 320bhp but have no proof, so i just took it as standard....
What upgrades can i do what wont cost the earth...want it remapping but want to get the most out of it, its got a sports cat on but just ordered a decat, its got an apexi air filter, 3" exhaust as far as you can see and a front mount intercooler but i dont know if its standard... Any help would be appreciated... thanks andy

Why not drive it first,get used to it,then think about upgrades?
Welcome by the way.

Thanks iv actully had it for a couple of months now and it isnt a slouch like but i previously owned a 350bhp impreza and want it as quick as that really...should have waited and got the 320! Ha ha .....any advice would be greatful

De-cat pipe on the way! How much difference would a tubeular manifold and bigger turbo elbo make?

 

[Wayne'o]

de-cat pipe on the 260 may mess up the emission as i'm sure there is a CO2 sensor in the cat of the 260

could be wrong

 

[andyw08]

No your right mate but its just before the cat and none after it so the reading are took before it gets there....been told theres not much that can be done with the 260?? Is that right?

Loads can be done to the 260. Chuck a set of 272 cams in, change the hotside on the turbo for a 10.5 and a 3" downpipe back exhaust and say hello to 410/420

 

[andyw08]

When you say just change the hot side of the turbo do you mean just the exhaust side? And would it not be better with a whole bigger turbo? ha ha

No not really as it's plenty efficient enough for that power. My mates is only running 1.70 bar at that power

 

[andyw08]

So is it ok to have these 272 cams on stock springs...iv read you can have up to these with stock springs?? Is this right? Thanks

Regarding the cams. It would depend on which manufacturer. 272 cams are a generic term. And can have varying ramp rates etc

 

[andyw08]

Iv seen cosworth ones for £337.45... is there any you recomend?

 

[RsvRob]

The prefered choice are kelfords. As they give good performance gains, idle and drivability. But do some research for opinions.
With the cosworth m2 cams I'd fit uprated springs as they have a high lift rate.

 

[andyw08]

It says its 11mm, any idea what lift they can be with stock springs? I dont really want to take the head off if i can help it....thanks

 

[RsvRob]

It's hard to say. Some suggest that all 272 rated cams should have uprated springs. Some suggest it's a matter of course to change springs dependent on mileage. Most others that don't need uprated springs are around 10.5-10.8. It doesn't seem much but...
There are however opinions that running the high lift cams are still ok on std springs. Just so long as your not running to redline continuously lol

 

[andyw08]

Ha ha who tunes their cars up and doesnt use it ALL my cars done 52,600 miles so not that many really....i dont know what to do, im a mechanic so i could do it all myself which would save me a bomb and id rather have my engine running safe than risk it but were do you stop....id have to buy new head gasket then new head bolts i assume, inlet and exhaust gaskets....deffo want it camming tho, how much can you get kelford cams?

 

[RsvRob]

Kelford 272 cams £500 New
8mr headgasket £40
Bolts you might aswell uprate to arp £115
Other gaskets of original multi layer metal would probably be ok

 

[andyw08]

Would you do the springs with the kelford cams? And whats the crack with the 10.5 hotside? ha ha
