Im not after top power etc, but after having 2 quick blast races with a civic type r and a phat porsche, ha ha that was fun, only about 9 car lengths behind him at the end ha ha ha

anyhoo, i relaised the scoob wasnt as quick to accelerate as id like, its a 95 wrx standard intake with a dump valve and exhaust system

cant spend much,just wondered if there was anything DIY style to increase the torque or acceleration ?

i know there isnt but i can hope ha ha

good chrimbo all

Get someone who knows what they are doing to up the boost level and fueling to suit

decat a must!!!!...then as above

cool,cheers.
thing is, the 95 wrx ecu isnt mapable is it ?

so if i mess with the fuelling decats etc wont i have to buy a £600 ecu and £200 map session etc, ??

Slowboy Racing

You can have it mapped using the ESL live which works out at around £600 fitted and mapped.

Failing that a well set up boost controller will see a increase in power.

yeah,a manual boost controller might be the way to start,start off easiest/cheapest and go from there, £600 is a tad to far at the mo.

its running 0.9 bar,whats the max on standard fuelling, 1.1 ?

cheers

stick below 14psi (1bar) and u dont need to remap to decat it, i did it with mine ages ago and make a nice difference to responsivness

eggy

get a fuel pressure regulater,,should give you faster response. don,t trust the one,s on EBAY as (90%) of them are crap...

cool,cheers guys

so,

decat
manual boost controller,is 0.1 bar increase worth it tho,as its at 0.9 already
fuel pressure regulator dont they have one already ?

cheers guys

Brun

The std FPR at this level is more than up to the task

eggy

Best to get an ajustable fuel regulater .....SARD,,FSE,,there are a few to chose from ,,NOT to sure what presure your car runs at normaly , but set the new one at between (3.2 to3.5 BAR) and you will see a diference in driveability and response ,,,,cost about £100

Porting the standard Exhaust headers will give a nice increase in torque especially with a Decat.

scooby-power

or get your self a scott t chip off this site , it increses boost and fueling to match not that dear either, you can get him to fit it to an ecu so its just a case of swapping ur ecu over, of fit the chip ur self to ur ecu,

weso

Err, I wouldn't raise your boost to anywhere near this level. Your car will go like a rocket for 10 yards, and then it will blow up. Stick to 1.1 bar max.
Weso

green un

he means fuel pressure not boost pressure!

it would go like a rocket though

weso

whoops.
I'll get me coat...

or jus give me 10k an u can have mine, its fairly nippy

why would upping the fuel pressure make it go like a rocket ???

if it was running rich it would be running even richer.
if it was running lean it might help it but it is a bit hit and miss and could certainly cost you a lot in terms of engine if you get it wrong, or just cost you a lot more petrol for no impact.

Get it mapped - simple as.

Then you would know it is actually running correctly, efficiently and getting the best performance possible.

You could also try lightened pulley, flywheel or just making the car lighter to improve acceleration.

What Dunc said. Do not muck about with fuelling unless you know what you are doing and are monitoring everything carefully on a wideband. It wont buy you any power without leaning it off and tbh you are best leaving that to the pros.

They run quite rich to start with (as rich as 10:1) on a Z4. Thats if it is running properly to start with, which is rare tbh. Part of the mapping process will be to give the car a health check which will turn something up in the majority of cases on old imported classics. Ask any mapper for war stories and I'm sure they will have a few. This is one of the main reasons I stopped doing postal maps, the cars I did get to see gave me a few scares.

If a remap is too much money then an engine rebuild is as well, upping the boost without checking or altering anything else on a 13 year old engine making the thick end of 300hp is a bad idea.

Nail. Head. Hit!!

You wanna play, you pay!

Simple as!

Mother Theresa

Get smaller wheels - instant torque.

young'n wrx

You shouldnt be haveing any problems with a civic type r and as for porkers it depends what model.

full exhaust system
panel filter
small diet
remap/remap chip

should see a healthy increase and turbo spool-up will be quicker!

have fun!

Stick the lowest profile tyres on you can find !
225/35*17 looks good on a new-age, etc. lowers gearing by 7% equal to about an extra 20 bhp.

DunxC :- thinks laterally

saiklon

Install an MBC but don't go mad with the boost, set it at 1 bar. Even with an MBC set at stock boost level you will see an improvement in gear 1 and 2 because it will be boosting higher than with the ECU control which limits the boost in those gears to about 0.6-0.7bar.

A decat will also help.

borat52

Thats super advise imho for a budget power upgrade. Decat and scott.T chip. Will safely up boost to 1.1bar and should give you about 280 bhp relatively safely. Boost controllers without proper monitoring are a recipe for dissaster.

LOL... do not do this! Your fuel pressure is fine as it is, the standard ecu is already running the car very rich @ WOT so increasing this further will just lose you power and increase mpg. How to waste £100 in one easy go and probably kill off the 13 year old fuel pump.

A good few years ago my old wrx (MY93) had a full decat, induction and dawes device boost controller set at 1.1 bar and it got 250bhp at a rolling road (remember these engines are now well over 10 years old so will down on factory power in all probability). Removing the dawes device and fitting a scoobyecu (1.1bar again) saw power runs ranging from just under 290 to 270bhp. This proved the easiest and best value for money upgrade....

I'd be interested in a little torque increase, too.

Ported headers should see a little increase?
