It could be an interesting thread to see who has the most powerful 2.5 UK car on the standard turbo?

Pez

See engine wise you're only a front mount behind me... Get a front mount and with the piston work done i expect you'd be ok to get more than I'm running. Think Bob kept it reined in a bit for safety rather than going ***** out when mapping it.
Would be interesting to see tho what power everyone is running on their original turbos for sure

Pez behave mate your making me want a front mount. Lol
I really need to do my suspension first before anymore power mods.

what front mount are you running on the hawkeye? i have looked into this and found most need to have the bumper bar removed which has made me hesitant. also, how much was it and were from, cheers, Lee.

Pez

Lol you know you want a front mount really ;-) I'm running Tein coilovers at the moment, not a bad kit but i need to get it set up right cause at the moment it's just way too bouncy for uk roads :-s
Front mount wise I've got a hyperflow monster on mine, same kit that the litchfields use, and apparently one of the biggest ones you can fit on a hawk. Price wise it ain't cheap, with the air relocation kit to the inner wing it comes in well and truly over a thousand pound :-s but then you pay for what you get is my line of thinking

Pez ur a bad influence and as such I am cancelling my subscription to this thread with immediate effect.
Lol

Ur right I do want a front mount but the coilovers are the next pressing issue. Though about the Tein set up and it's been mixed reviews that I have heard. I have been in a Hawk that has em and they seemed really good. Alot of people say th B & C set is just as good for less money. Not sure which way to go but will have to do more research while saving up for them.

Pez

Lol :-D I'm very good at spending offer peoples money that's for sure Lol

Tein are good, once set up but like you I've also heard very mixed reviews about them... The fact Tein offer a full rebuild service must indicate something :-s but as to date I've no issues (touch wood) and Tbh they were already on the car when i brought it so they'll do me until either something breaks or i win the lottery lol

Well, if we're talking uprated internals and a bigger blower, have a look at mine

I suspect the OP is more interested in figures from cars on the Std blower and non forged engines though.

Pez

I'm liking both of your twos specs definately the next step for me is some kind of forged build or such like. Get the internals up to scratch ready to handle more power and safely.

Sounds like a sensible idea as i have heard of the pistons giveing issues with relatively low power and then some with high power being solid. When i was buying mine I took it to mean that there was no way to be sure if the pistons could/could not handle the boost without melting. I was lucky enough to be buying a car that had to have the head gasket done so for an extra £1k they put forged pistons and uprated head bolts in. This is the reason that i have done the pistons before as other wise changing the pistons would of been more like £2.5K. When buying a car for £10k + the last thing you want is smoke coming out the back it would make you .

Similar spec to mine, but I am running lateral Gt headers and Harvey up pipe aswell.

I too am running the AVCR which is getting mapped by Andy F next week. Who did you mapping?

blackhawk56

iTrader: (1)

andy f also mate ecutek with racerom top quality lol goin back to him next week as car is in gettin fmic fitted at gsr now

14N-FR

iTrader: (3)

I have racerom on the car just now, with the AVCR fitted but not mapped. GSR built my engine actually.

What FMIC you going for? I just finalised all my pipework there hence the reason its going back to Andy F on Thursday for final mapping.

Are any of you running 400bhp through the WRX transmission or are you all using the sti 6 speed box?
Thanks

Matty81

Would definitely need a 6 speed. Heard they are only good for 340/350 on the wrx.

G10

Thanks Matty, do you think it would be worth strengthening the 5 speed box? Also, is it a simple swap replacing the 5 speed for the 6 speed? Cheers

Matty81

By what I've read on scoobynet it's far from an easy swap, and expensive aswell. I'd just try and get as much as possible out of the 5 speed if you really wanted to add more bhp. I'm no expert, someone would be able to tell you more than me.

On-the-bog

hawk 5 speed box will be fine at 400.

BrownPantsRacing

iTrader: (6)

^^^ Agreed. Hawk 5 speed is stronger than the older 5 speed boxes. Should be fine for 400bhp.

Mark10sti

iTrader: (2)

Very similar to mine I made a little over 500 at the wheels @1.7 bar

Nezscooby

I was told its not safe to run over 450 bhp on 2.5 block forged

BrownPantsRacing

iTrader: (6)

You were told wrong then!


It all depends how the engine is built and what parts it uses. The standard rods are good up to 500bhp (in theory) but if you upgrade pistons, head gaskets, head studs, rods and get the inserts fitted to the block to make it a CDB then it could push 500bhp easily. There are quite a few people running a 2.5 engine well over 500bhp already on here.


All depends how deep your pockets are, but anything is possible.

On-the-bog

I wouldn't want to risk it beyond 450 without closed decking it. Liners are just to thin so flex or worst case fail

ahh man. wish i hadn't read this thread now.

I have a fully forged 2.5 sti spec D with decat full stainless genome exhaust and mapped running 337 with standard top mount.

Now i feel that i need to be running more and its a little tame for the work thats been done!?
