hey guys need to pick your brains.

recently purchased a nice forged closed deck 2.5 from roger clarks and im just wondering whats the best auxillaries to run with this? eg turbo injecters ecu etc.

im not after no stupid bhp just want some good bhp/ ft/lbs

the connectors on my injectors are yellow does this mean they are 440 injectors?

current spec is

2.5 bottom end
v3 heads plus cams etc
un-equal stainless manifold
full 3" stainless exhaust with de cat.
aftermarket panel filter.

 

sorry ment to say its a 1997 wrx import.

 

What do you deem as "not stupid"?

 

Stick with advice from Roger clarks mate.

 

as in i dnt wnt 450 500 bhp.

400 tops but wld prefer like 350 ish around there

cause will have plenty low down power.

 

Front mount, 550cc injectors, fuel pump, fuel pressure reg, apexi power fc, K&N induction kit and a TD05 20G turbo. This should get you around 380 - 400bhp and similar amount of torque.

orite i want to stay away from front mounted cooler, don't really wnt 2 cut the bumper.

so il aim for lower figures then. cheers

 

With you current tmic you are limting yourself to around 330 - 340bhp, anymore and you run the risk of high charge temps on a spirited drive.

yeah someone else said that. just not keen on the front mount. so guess my figures will have to stay around that mark then.

wat injectors and turbo will be best?

 

Keep your current 440cc injectors they will be fine and same again with your current turbo, which should be a VF22 or VF23.

cheers mate, il run it in then take it to rolling road to get it checked out. sure they will advise me

 

get yourself a newage sti intercooler as there good for 400+

 

sounds good to me mate cheers

 

so you bought an engine from RCM and your asking us advise

jim

 

yeah i've e mailed tim at rcm as well. just fancyed a few opinions.

 

I will have a hyperflow top mount intercooler from a newage for sale in the next couple of days if you are interested.

: Subaru Impreza Hyperflow Intercooler

price?

 

Bang vs Buck at your stage for 400bhp....

550cc injectors or FPR to whack up your current threshold
Keep the panel filter (but that does depend on your routing to the airbox and what version of airbox it is)
Pick up a 2nd hand TMIC (Ver.8 etc)
Appropriate turbo

Various ways to skin a cat if you ask me.

 

Would want £350 for the intercooler

Banny

 

yeah il just run it in then see wat my options are. costly project but will be worth it.

 

Why did you buy a Closed Deck 2.5 bottom end when you have no intention of going above 400bhp? A CDB 2.5 should easily be good for 600bhp+ and so you engine spec is way way over spec for what you want?

 

Sorry to take things a little off topic, but what kind of figures will an 18g potentially make on a 2.5?

 

thats wat i wanted to make it very reliable. if i want to go more power then the engine will be good for it.

wanted a fresh start engine and 2.5 was what i wanted. plus get more bottom end grunt from it. and its something different. everyone man and his dog has an impreza but not everyone has a 2.5

so now il have a different car which will be solid at the bhp i want to run

 

fully closed deck 2.5?
It would be a crime to run anything less than a fully rotated garrett set up and gun for 500+ bhp.

are you sure its not an ej257 semi closed deck?

 

think you could actually be right mate ej257 is wat it is so yeah semi closed deck. sorry my mistake.

 

Roger Clark Motorsport - RCM Product Detail

is this what you bought?

 

no need to apologise
but it does limit things slightly. I would say that 1.6bar is now the top target.

 

yeah i believe that it mate, but i've got forged stuff in mine so its not just standard.

still get some good power out this engine. il just see how far i want to go

 

if you can afford the supporting mod's to take you over 400 ie injectors and turbo etc etc and then just get it mapped to what you want ? that way if yu want to take it to 500 you can just get it remaped etc etc ??

 

You also need to remember the 2.5 is very good at breaking gearboxes, dont forget to consider this part.

Your current set up will see around 315 BHP and 330 Torque.
