Barts. Posted July 1, 2015 Share Posted July 1, 2015 Hi all I've been looking at td05 turbos on eBay and was wondering if it's just a simple swap job on my 2001 wrx which has the td04 turbo. Thanks in advance Quote Link to comment Share on other sites More sharing options...
BoozyDave Posted July 1, 2015 Share Posted July 1, 2015 they are a direct fit, but it will need a remap when fitted Quote Link to comment Share on other sites More sharing options...
Gaulson Posted July 2, 2015 Share Posted July 2, 2015 As BoozyDave said, remap would be required. Also avoid cheap Turbos on eBay, they don't last well. Quote Link to comment Share on other sites More sharing options...

Lloydkent900 Posted July 14, 2015 Share Posted July 14, 2015 Can anybody tell me what psi my td04 turbo is able to run at please Quote Link to comment Share on other sites More sharing options...
BoozyDave Posted July 14, 2015 Share Posted July 14, 2015 you won't gain much running it at max PSI, the max it will run is about 16/17 psi, but the higher the PSI the hotter it runs, so warms the air up, so no increase in performance. a remap will got to about 15 PSI and give decent gains, but also look at good air filter, free flow exhaust, decat up pipe. All these will help the flow of air through the engine it's not all about PSI, it's about air flow and efficiency. A little turbo running big PSI and verging on inefficient or a bigger turbo running sensible PSI flowing more air and in it's efficient range 2 Quote Link to comment Share on other sites More sharing options...
Lloydkent900 Posted July 14, 2015 Share Posted July 14, 2015 Thanks dave most helpful. Just need to know what to run the turbo at because only running at 0.6 not sure what optimum psi is Quote Link to comment Share on other sites More sharing options...
Tidgy Posted July 14, 2015 Share Posted July 14, 2015 You dont need to worry about the boost mate, mapper will set it for you :) 1 Quote Link to comment Share on other sites More sharing options...
BoozyDave Posted July 14, 2015 Share Posted July 14, 2015 a remap should be done by someone that knows what they are doing with subarus, they will set it up to it's optimum. some blobeye WRX's can get 285-300bhp with a remap and a supporting mods. mine would only get to 265bhp, but the low down punch was great. don't worry about top end BHP, it's all about the midrange :D Quote Link to comment Share on other sites More sharing options...
stants Posted July 15, 2015 Share Posted July 15, 2015 Thanks dave most helpful. Just need to know what to run the turbo at because only running at 0.6 not sure what optimum psi is Are you after a figure of what yours should be boosting at stock ?

quit Posted July 15, 2015 Share Posted July 15, 2015 just seen your model number in the side tab: if its a 1999 car you got four options: 1. ECUTEK, about £550 2. Apexi about £350 for the unit then map / set up is another couple hundred quid but more people can do apexi or you can buy the cable to do it yourself 3. alkatek - can run maffless etc have launch control, dual maps, loads of toys but expect to pay out about £1k inc mapping 4. Open Source i.e. Eculabs remap basic is about £450 1 Quote Link to comment Share on other sites More sharing options...
