Ive been looking through lots of posts with people doing things to their car and the list seems to be endless, hybrid turbo,remap ECU, Change Cam,Change Intercooler, Fuel pump, decat etc etc.
All im after is something relatively cheap (less than £800).
I know a remap costs about £500 but is there any point in getting one with a standard car or do i need to upgrade the fuel pump before i do anything else?

I dont want massive power just a bit more. Currently only modifications are a back box and 18" wheels.

am i asking for trouble modifying a car with 50k on the clock?

Thanks

Mark

ps my pic is my old car i havent updated it yet.

 

For a start removing all 3 cats from the car will noticably increase perfomance.
Once you've fitted these its wise to get a remap.
You can get a downpipe, mid section, and an uppipe fairly cheap from the For Sale section on here.
What you definatly do not want to do at this stage is get a front mount. The Top mount that is on your car is more than capable past 350 bhp.

 

Bugeye sti only had 2 cats AFAIK...it does not have a cat or an EGT sensor in the up-pipe.

I'd de-cat and then EcuTeK re-map.

de-catted Bugeye STi's are prone to boost spikes without re-map or fiddling with the restrictor !

If i do a ful decat then it wont pass the MOT is that right? So if i used a high flow cat and a remap that would do the job?

Mark

 

yes it would but you get more go with decat.. just depends on whether you are able to refit the cat yourself at mot time.. for some that is a complete pain and for other people no bother...

Simon

 

no you won't, buy a second hand prodrive sports cat downpipe !
just as good as a decat in fact better as you don't have to mess about m.o.t. time

 

I think i prefer this no hassle option. Just have to find one now!
This should come in under my £800 budget (with the remap)?

thanks guys

Mark

 

I was always told the bugeyes had a cat in the uppipe??

 

agree less hassle at mot but it is still more restrictive than no cat

 

not on the Sti..

 

I had a 03sti ppp.
Sold all Prodive exhaust.
Bought a secondhand decat on here. Then panel filter and remap.
330bhp and 352lbft.

 

Ninja sports cat DP from Scoobyworld! £299! I have one along with a few others on here and our cars are all on the money with regards to power outputs.

You might loose 3-4 bhp over a full decat. No big deal and much less hassle as regards to insurance and MOT

 

I'd go for:
prodrive sports cat £250 s/hand
prodrive decat centre section £75 s/hand
Fuel pump new £80
remap £600

This should see IRO 330/320

Just over your budget though. Going for a decat downpipe would be within budget but would cause trouble at MOT time.

Hi Nick

Doesn't the bugeye STi have an uprated fuel pump already ?

Otherwise I'm in full agreement

Shaun

 

Think it only came as part of the PPP.

Is there any benefit from doing everything bar the prodrive sports cat? just it pushes up past my budget and i really dont have the cash (petrol money!)

Mark

 

The Cat in the DP is the most restrictive part of the exhaust mate - it's not just power it robs, but also has a deleterious effect on the spooling characteristics of the turbo. I'd wait till you can get that sorted before a remap for the best gains, or you'll only have to pay for two maps, the second after you've changed the DP at a later date!

Oh right so it would actually be better if i bought
prodrive sports cat
prodrive decat centre section
Fuel pump new

and run with that for a while then get a remap when i can afford? Will the car run ok without the remap for a bit? (Ie not damage anything else)

Mark

 

Mark

The Bugeye STi can have boost spike issues when de-catted so really needs mapping (or the restrictor re-drilling) when de-catted.

I'd buy cheaper de-cat downpipe and put on the OEM downpipe at MOT time

A bit of a hassle but the cheapest.

Save up for a second hand Prodrive / Miltek sportscat in the meantime.

Shaun

 

Mine ran fine for two years with a full TSL catted exhaust, except for a Check Engine Light, (emissions out of spec.) no spikes just a bit of over fuelling....

Then had the re-map and WOW ! wish I'd done it two years earlier...

Dunx

P.S. A friendly MOT tester can hook-up a nearby hatch for the emissions test.... Until they start checking for ecu details... Big Brother.

 

Dunx.........you were lucky LOL

Gotta agree about re-mapping and the "wow" factor for the newage

How Subaru let the newage leave the factory without 280-300 BHP is a mystery to me !!

Shaun

 

Absolutely, but mine has some issues as I close the throttle at "motorway" speeds... Not very funny.

Dunx

With all the extra weight, it needs 330 bhp standard ?

P.S. Mike Wood told me on here that standard clutch is good to 400 bhp, so long as you DON'T slip it ! ! !

 

Dunx

I have a bugeye with an induction kit and lift off at motorway speeds is a bit iffy

I'm running about 400 odd BHP and I crippled the OEM Clutch (now on an AP Organic) and the gearbox not long after LOL

I have to agree that the lardy newage needs 325 odd BHP to match the 280 BHP of the lighter classic

change your fuel pump £80
prodrive sports cat s.hand £150
after burner b/box s/hand £150
2 1/2 bore centre section ( ebay) £70
panel filter £30
re map £300

should give a healthy 330bhp 330 lbs torque
The prodrive centre section is just a standard sti part
forget induction kits waste of money unless you are changing your turbo or looking for 400 b.h.p.
The prodrive sports cat will give beter spool up than a decat,
and you loose around 1 b.h.p according to p/drive comparded to the decat.
