hi all ,,,i have a 1993 wrx import,,,,running all standard with a td04 turbo and just a ram air induction ,,
i have got a ,, tdo5 16g turbo,,f/m intercooler /z4 ecu /and full de-cat exhaust
can i just stick them on as i have been told my car can,t be re-mapped
i dont want loads of power just a bit extra will be nice
any help or advice please ,,,thanks

 

Should already have a td05 on there.
Those mods should be alright without a remap although the fmic is a waste imo unless you are going for a lot more power

 

WRX Wagons have TD04's and WRX saloons have TD05's (for your model year) so there is something amiss somewhere as you have a saloon

Aye my old silver Wrx was a 95 and had a TD05 as standard whereas my 99 UK Scoob had a TD04.

Did early Wrx's have the TD04? sure the didn't, what year is the Z4 ECU from Tony?

 

thanks for all this ,,i changed my engine not long ago and it is definate a td04 thats on it ,,it is a saloon ,,???,,maybe it has the wrong one on it ,,andy the z4 ecu i have my eye on is from a 1995 yellow 4 plug ,,but was thinking of having it chipped
won,t i gain anything from the f/m intercooler ,,

 

Pass.

 

Early WRX and UK cars had td05 (92-96) then UK cars went to td04 and WRX went VF.(saloons)

Z4 is from late 94 to 96 WRXs,waste of time chipping it really as you can chip your own ecu,you will gain something from the fmic but not as much if you get a proper remap.

 

so it is going to be better with the td05 16g ,,as it should have one on it ,,how can you get a proper re map on this car ,,or what would any you do if it was your,s,,[pleas dont say sell it and get a sti] lol thanks for any advice

 

Sell it and...



But seriously...

Get it remapped properly with something like an ECUtek ECU. With the FMIC and TD05 16g, you'll see more of an increase (and a better overall drive) by having it custom mapped. As said in the other thread I'd be worried about unmapped mods causing your car to run lean.

 

Just buy a Polar Performance chip for your current ECU. Get the one mapped for the TD05 and you'll be away. The chip will be mapped for de-cat as well. I run one on mine not a problem. I also run a FMIC as the early TMIC is rubbish and to buy a good one costs almost as much as a FMIC, with the added advantage if you ever want to do track days or high speed runs you can. (There are reports of air not going through the scoop to the TMIC at high speeds on early cars). I added a dawes device to bring up the boost to a true 1.1 bar to take advantage of the chips raised levels - 303 bhp / 290 ft / lbs of torque, running slightly rich still on 380 cc injectors. Make sure you get it rolling roaded to check everthing is as it should be!

You could go down the ESL daughter-board route (£600) or Simtek (£1200), but with minor mods and a 16 year old car is it worth it? Its up to you in the end.

ps If it is the PP chip route, make sure it is genuine not a cheap copy.

 

WRX wagons have TD04's and 220ps output, the saloons had TD05's (92-96), amazingly the 94-96 UK cars all had TD05's before they changed them to TD04's on the 97 onwards models

The ESL (Enduring Solutions Limited) daughterboard is your best bet for a proper remap but it is about £600 which is a lot (worth it imo but still a lot on an early car).

With my 93 wrx i had a Z4,decat,manual boost controller and it made 270bhp,the boost controller was set up on a rolling road to make sure it was fine.

But with increasing the power/torque you will be putting more stress on the transmission

But i did sell it and bought a 98 STI Type R

 

thanks for all the help ..im reading them all and taking it all in ,,,thanks

 

pre mapped polar performance chip £195 plus a socket soldered into ecu £50 job done , 280-300 bhp , proven map been around for about 8 years bought mine off scott about 8 years ago car ran great no probs cheapest option .
