ste91 Posted March 23, 2010 Share Posted March 23, 2010 I've always considered FPR/FCD's lame, better to go for a piggyback or atleast a plug & play ECU.Also I've heard of T25's being used on B16's, surely it would be slightly laggy on a 4EFTE? Quote Link to post Share on other sites
k1r4n Posted March 23, 2010 Author Share Posted March 23, 2010 im saving up for fcon at the mo, trust me when i can afford it i'll deffo get it. but for now i'm working with what i can.i know the t25 was designed for a bigger car and it will be a little more laggy but only on launch otherwise it should get some good power rite?i thought lag is only an issue if your at low revs trying to put your foot down or on launch. correct me if im wrong by the way Quote Link to post Share on other sites
ste91 Posted March 23, 2010 Share Posted March 23, 2010 What sort of power are you aiming for? You might be better off with a different turbo depending on your goals, I'm assuming below 250bhp as you're runnning standard internals. Quote Link to post Share on other sites
Danturbo4311 Posted March 23, 2010 Share Posted March 23, 2010 I used to run a t25 with a .64 rear housing off a 200sx with 360 bearing & uprated seals, on the dyno it made208bhp @ .7bar268bhp @ 1.1bar I've been looking for the graph but cant find it at the mo I also road mapped it & ran it at 1.5bar was alot quicker but didnt get it on the rollers before switching to the gt28rs, it wasnt really a laggy turbo was on boost at 3500rpm, the figures above were on a forged engine with 460 injectors on the emanage blue, uprated fuel pump & other things cant remember it all but, it was on, std head, cams.your definelty gonna need manifold, downpipe, external or internal wastegate set up i was external. also on a standard engine i wouldnt like to say how much boost you could run.

You might be better off with a different turbo depending on your goals, I'm assuming below 250bhp as you're runnning standard internals.to be honest i want 200bhp at the wheels, i'm aiming for a controllable but fast daily drive Quote Link to post Share on other sites

Danturbo4311 Posted March 23, 2010 Share Posted March 23, 2010 It wasnt bad now its much faster now, it will give you 200hp at the wheels & probably a few spares horses just incase lol, however a td04 would be a bit more responsive & also give you 200 at the wheels & they are alot cheaper to get hold although t25s are not that expensive really.With the injectors standard ones wont cope although it depends how much boost you wanna run but theres no point having a bigger turbo & running it out of its effiency range its about matching the turbo to what you want.Only other extra bits i think you may need is some better heat range plugs & thicker leads (basic stuff, as on the dyno at 1.1bar it was having problems with the plugs blowing out so had to re-gap them), electronic boost controller , theres probably somethings i forgot but theres always something else which is needed.

Danturbo4311 Posted March 23, 2010 Share Posted March 23, 2010 Its made by WEPR Im still using the same manifold & downpipe as they fit the gt series turbos (gt25, gt28) aswell, & the mani & downpipe are both stainless steel some people have problems with the stainless cracking but I've not had any problems yet & been running them for about 2years now, the downpipe has now been cut & welded to fit a side exit exhaust.
