i have an impreza turbo 2000 with the prodrive performance kit and a straight through exhaust system turbo back i was wondering if the p1 throttle body would improve performance.

cheers

 

nope..

 

The P1 throttlebody is esentially the same as the 99/00 WRX or UK turbo variant - IIRC the WRX/UK turbo item has a second cable drive on the spindle, for cruise control to be fitted

Just port your current one and knife-edge the butterfly plate to make a (slight) improvement

 

iirc a decatted down pipe wont do you any favours on a PPP either!!

 

what is iirc? and why would the decatted downpipe not be good for the ppp?

cheers

 

(iirc) means if i remember correctly. The ppp is fitted from factory therefore adding something like a decat downpipe afterwards could mess the fueling up.

Hope that helps

 

yes it does cheers, what would be the solution for this? next stage remap?

 

A remap would sort that out easily enough

 

what remap do you suggest? ecutek?

cheers

 

Best asking a good mapper and what they prefer to map, and what will give you the best result while being safe

 

If the car is pretty much standard an ecutek remap is quite capable, people have ran 400+bhp on an ecutek remap, with the supporting mods of course.

 

yes mine is basically standard, apart from the decat exhaust turbo back and the ppp

 

Don't remap the ppp, they sell for £200-£300, is it a my99/00??? if so just buy a second hand E3 ecu for about 50 quid.

Ps i have one out of my old rb5 for sale

 

If the guy plans on modifiying the car (even with a decat) the car WILL need a remap to make sure the car is running safely, and get the most out of the modification

 

Are you really that thick that you can't work out my post

You buy a standard E3 ecu for about 50 quid put it in the car and remap that, then sell the ppp for about £200-£300 and put that towards the remap!!!!

 

What age is your uk turbo first to see if it can be mapped.

I would'nt go advertising a classic pppecu for £200-£300 as you'll still have it this time next year, Ive just seen a simtek for v1+2 go for £500...

And that's only in october, you'll be surprised how many people still want these!

Obviously i'm only presuming he's got a MY99/00!

 

its a turbo 2000 awd year 2000

 

You've got a rare ecu there, that always seem to produce more power than what stated (237bhp & 258ft/lb) when i put one on my standard RB5 it produced 261 bhp and 260ft/lb and a fair few others have said the same on the RB5oc. There still sought after and people still want these, so follow my advice above and sell it then put the cash towards a ecutek remamp on a standard E3 ecu!
Do a search on here and you will see that there has always been the debate on whether or not it is safe to run a decat without a remap, but end of the day it's upto you!!!

 

what would happen without the remap? are we just talking poor fuel consumption? or damage to the internals?

 

There is a chance of the engine running lean and going pop,but then there's been people running a decat without a map for years and no probs, but have a read up yourself then make your mind up!

 

is it best to have everything fitted before the map like all decat and freeflow uppipe ect?

 

The package is mapped for the parts that are on the car, this included the downpipe cat, removing that cat will go beyond what the ecu can control and this means spikes in the boost, which means det.
These do det, i know because I have seen it do it (i use to own a PPP'd MY00 turbo in sonic blue ) and she was always run on super unleaded fuel.
It will be worse in cold weather btw, det will eventually cause engine failure, I "fixed" mine as soon as I saw her detting on the knocklink by drilling the restrictor pill out (but your going to need a knocklink/ks3 to monitor if you get any more det, or remap the car).

Tony

 

I was in the same situation earlier in the year,my MY2000 had a prodrive ecu fitted along with Y pipe & backbox.I simply sold ecu for £300 to a guy in the czech republic ,£85 for the backbox & £30 for y pipe and put the money to having a remap.You can as said above also buy a E3/Y7 ecu off ebay for £40 - £50 if you ever decide to take your car back to std , and sell your chipped ecu for a few hundread quid - cant loose really imho.

 

cheers guys has helped alot and probably saved my engine jus a question about when i get a standard ecu will it muck up the immobiliser atall or are there any problems with swapping ecus?
also should i have everything on the car (fully decatted exhaust ect) prior to the remap?

cheers

 

no the ecu will just plug straight in, the imob has got it's own unit!

Yes you need all your mods on first or how would the mapper know what to correct and improve the fueling/performance to

I've got a E3 ecu that came off my old RB5 that will plug straight in, it's been sat under my bed for the last 2 1/2 years, you can have it for £50 if you want, there's no rush though it's keeping my spare passenger wing company

 

E3 it should be either an AE800 or an AE801, the AE802's were common on the MY00 uk turbo's.

Tony

 

Tony the E3's were in 2 colours, on the early 99 cars were red and had the code no's AE800,later they came in black or red and had the code no AE801.The MY 2000 had a green labelled Y7 ecu with the code AE802. For mapping purposes the 800/801 seem to be a tad more responsive than the later 802,which is why i had the 800 fitted in my MY2000 car.

Later Model Year 1999 uk ecu AE801:
