Can i put the following onto my STI 8 and drive without a remap?

• TSL Thundercat Downpipe
• TSL Centre Section
• Prodrive Back box
• TSL Panel filter

Just looking into the options avaliable as i am considering fitting the items myself to save some money.

I will then drive to see Paul @ Zen and have my car mapped (fule pump will be fitted at this time)...though it may be afew weeks after the parts are fitted...


Any advise wecome?

Should be ok, just keep it off boost and take it easy until remap.

I will be doing a similar thing soon when I have a VF35,inj and fuel pump fitted the day before driving ~100 miles to be mapped. Should be ok, fingers crossed..!

Neilo

keep it all off boost as that way the car operates in closed loop mode so can compensate for everything easily.

Although for what youve suggested, it shoudl be too bad anyway ntil you got there....its only really important if you swap over turbos/injectors etc..

dogpole

Is the closed loop mode just a newage thing?

Back in the classic days we were all running full decat without remaps

Cool...thanks

Neilo

newage ecus are a little more advanced that the old classic jobbers though...

If you're just decatting it and replacing the filter element, you'll be absolutely fine, it will def benefit from a remap but there's no need to drive off boost

i run an 02 wrx on a full de-cat plus hi-flow filter and just re-set the ecu everything is fine but i wont be doing anymore engine mods till i get re-map

SamUK

No not decatting....The Thundercat downpipe has a sports CAT within in...it does however replace the second CAT Pipe also.

Sam, you'll be absolutely fine on those mods without a remap.

As mentioned, a remap will help make best use of the mods but I wouldnt say it was absolutely crucial at that level, so get the exhaust done and relax... like Neilo mentioned, until you start going a bit further like induction kit, full decat, FMIC its not life threatening.

(Im suprised Paul hasnt told you that actually )

Was only thinking of the following: keeping away from the full decat due to MOT reasons....

Thrundercat Sports CAT Downpipe
Centre Section
Back Box
Walbro Fuel Pump
TSL Panel Filter

Then a remap should see me near 330hbp mark...


Will be speaking to Paul in the next few weeks once i get the funds in to get the above ordered...

If you're handy with the spanners, just get it decatted and when it comes to MOT time, just swap it over. The other alternative is to find a "friendly" MOT test station

If you're going to uprate the fuel pump, it might be worth asking Paul if it would be worthwhile uprating the fuel pressure reg at the same time.

just got mine fully decatted and fitting up rated fuel pump and FPR tomorrow im wondering if ill be ok to drive it without a remap as well as im going to timeattack on sat a 300 mile round trip

Jay_bee

Full decat, presumably Walbro 255 & FRP (SX?), just take it steady. Id certainly say get it remapped sooner rather than later as it will be running pretty rich (but thats not a bad thing, its when they run lean you need to watch out for).

RA Dunk

its a henko fuel pump and SX FPR , as long as im in no immediate danger of blowing up on saturday mornings drive (ill take it easy) to timeattack thats ok lol

im getting remaped soon just waiting for my FMIC and turbo to be fitted first then get map done so it is on the cards

Aren't decatted NEWAGE STi's are prone to overboost..? (granted it's not strictly full decat but still high flow 100 cell cat).

Are the people here who are running decat/oem map actually talking about newage cars..?

For those that are, WHY..? It's a complete waste of time..! The later ECU's are so advanced they just pull the timing (iirc) so you end up with maybe 5bhp extra if that..!

Unless you're planning on getting it mapped it ain't worth it IMHO..!

Another thing, unless you're planning on running higher than stock fuel pressure (~3bar) then why fit an uprated FPR..? Stock FPR (newage) is more than capable of handling an uprated pump.

It's like fitting induction kits/dump valves etc unless you are going for BIG power (ie >400bhp) the stock (newage) components are more than capable and in fact better in most cases..!

I think people read the spec of BIG power scoobs and think that by fitting one or two of the bolt on mods they're going to get significant gains. It's all got to be balanced. Why waste your money..?

Andy F's project WRX is a great example of what you really need, although even he conceded (after fitting) that the samco intake hose wasn't really needed. Unlike the classic equivalent that was very restrictive, the newage cars (well 03> at least) have a better freer flowing design.

Time for me to take a chill pill, damn heat..

Neilo

hes just atlking about running the car while hes waiting for the remap....theres no issue there, only if you never had any intention of remapping....

jasonius

iTrader: (1)

Yep I know mate, I'm just having a dig at the people who always say you don't need a remap (regardless of what scoob it is)..

jasonius

iTrader: (1)

PS I'm stalking you today..!

Jay_bee

iTrader: (1)

Did anyone say

"you don't need a remap (regardless of what scoob it is).."

If you're refering to moi, Im pretty certain I said it would be fine without the remap but to get the benefit of the modifications you WOULD need the remap (which, as has been pointed out he did say he was getting). He only wanted to know could he drive the thing until he got the mapping done.. which the answer to that is yes

On another note:

I have a drive on ramp, is it a difficult jobby to get the two CAT pipes off and put the ThunderCat downpipe?

Jay_bee

iTrader: (1)

The centre pipe isnt tricky but the downpipe is a little more "awkward"

jasonius

iTrader: (1)

Lucky bugger..!

Depends on how handy you are with a spanner and how many 'spanners' you have..?

Up-pipe can be a right barsteward..! In fact they both can if you come across any siezed nuts..!

Jay_bee:
point taken and it wasn't specifically pointed at you.. Just some people claim that decatting a newage car is well worth it without mapping, when in reality it isn't. I only wish it was..

No probs matey

Sam,

With regards to the awkwardness of the downpipe... just remember... when you think you undone all the nuts... theres probably another one you've missed hiding out of sight and Im sure you'll enjoy getting the heatshield off

Guys, I would seriously reconsider fitting the parts without a remap or at the very least get someone to have a listen with det cans, I've seen a number of cars with decat systems and standard fuel pumps leaning out above 5k.

Not speculation but fact.
