XtremeChief Posted June 20, 2007 Share Posted June 20, 2007 (edited) Hey there im almost finished my rb20det into my 180sx conversion just wondering is it still possible to use my car with stock ecu after i change the turbo to a t04e or do i need to buy a EMS? Mod my car have are: Trust FMIC 3" turbo Back exhaust t04e (going to run 10-12psi) Turbine .63 Comp .60 (too Big? Aiming for 220-250rwkw?) Os Giken Adjustable Cam Gears walbro 341 Should i get a rising rate Fuel Pressure reg? Will my car run like a sack of *poo* or will it have basically small to no Change on how it will run?

BHDave Posted June 20, 2007 Share Posted June 20, 2007 sigh... Do yourself a favour and have a look in the rb20 sticky thread at the top of the forced induction forum and see what turbos work on an rb20 for what you want to do. then do a search for t04e and see what people think of them. Then decide if you still want to install it. Link to comment https://www.sau.com.au/forums/topic/173635-rb20-turbo-to-t3t4-t04e/#findComment-3190456 Share on other sites More sharing options...
1400r Posted June 20, 2007 Share Posted June 20, 2007 car will run fineish under 5,000rpm i.e before you hit boost if you want to putt it round to the tuners it should be fine just keep it off boost and make sure you still have stock fuel pressure on the reg and not way under or something stupid ps t04e will suck the wang if your only gonna be running 10-12psi you must have low power hopes i.e under or around 200rwkw why not just go a vg30 turbo or a rb25 they will be much nicer to drive and still make or get close to the power you want Link to comment https://www.sau.com.au/forums/topic/173635-rb20-turbo-to-t3t4-t04e/#findComment-3190537 Share on other sites More sharing options...
XtremeChief Posted June 20, 2007 Author Share Posted June 20, 2007 Forgot to mention turbo has Turbine .63 and Comp .60 Should of done some research but impulse bought but can anyone see any Pro's to this turbo on a rb20det and what would cons be?

R31Nismoid Posted June 21, 2007 Share Posted June 21, 2007 Lots of cons. Its mainly depends on the turbo spec, but i would be of the assumption it wont be the best.

LBR33 Posted June 21, 2007 Share Posted June 21, 2007 It really depends on the ar's of the turbo as the right turbo can pull like a freight train and produce over 300rwkw on a rb25 Link to comment https://www.sau.com.au/forums/topic/173635-rb20-turbo-to-t3t4-t04e/#findComment-3191031 Share on other sites More sharing options...

rev210 Posted June 21, 2007 Share Posted June 21, 2007 (edited) sell that piece of crap turbo and buy something else, put a stock one back on and save your money for something thats actually good. Buy a sliding hiflow, you can't get cheaper. It bolts on and unlike the turbo you have it has an actual power curve.

S13 SecaBoy Posted June 21, 2007 Share Posted June 21, 2007 i have a similar turbo on my rb20 silvia... specs are: 50 a/r compressor .63 a/r turbine .57 trim still running on the standard computer and its running REALLY rich... its not pinging and not detonating... but it sure as hell needs a tune.. i have no boost before 4000rpm... but then it pulls (sideways) until redline... i would strongly recommend getting a tune sooner than later... no point running it without a tune...

discopotato03 Posted June 22, 2007 Share Posted June 22, 2007 IMO the only "T3/T04E" - actually TA34 in Garrett speak worth having is one called a TA34-1 , do a search . Is supposed to work reasonably well on an RB20 . T3 flanged , .58 turbine housing and I think a 37 or 40 trim T04E compressor . Cheers A .

Roy Posted June 22, 2007 Share Posted June 22, 2007 The first RB20 i remember being worth is salt on SAU was CLint32 back in about 2002. He ran a HKS TO4E kit that was released for the RB20. He made good power, ran 12s, though i dont know exactly how responsive it was. But provided its an RB20 kit then you could do far worse. Hell grab the kit, run it for a whiel then update to a newer turbo, the manifold and wastegate alone are worth buying the kit for Link to comment https://www.sau.com.au/forums/topic/173635-rb20-turbo-to-t3t4-t04e/#findComment-3192589 Share on other sites More sharing options...

I'd shoot for a 50-trim T3/T04E with .48a/r turbine housing. They're pretty reasonable spool wise for a T3/T4E and are capable of some good power.

FATGTS-R Posted June 22, 2007 Share Posted June 22, 2007 (edited) http://www.skylinesaustralia.com/forums/in...st&id=19707 Thats a garrett factory fitted T3/T04E on a GTSR. They can work ok, for an old school turbo, if the combination is right. Thers a million types of T3/T4 so its hard to know what will happen untill you throw it on. It is a .60 TO4 compressor housing and the exhaust I beleive is 0.63, same size as whats on a VLT I beleive. No information on trims.

discopotato03 Posted June 22, 2007 Share Posted June 22, 2007 The one I mean uses a 40 trim T04E compressor and 50 A/R T04E compressor housing . The turbine housing is integral gate , 58 A/R and V band outlet . The stumbling block is using large trim T04E compressors on these crossbreed turbos , no way a T3 (small series like we have in Australia) can properly drive them . They create lag down low and the small turbine/housings create restriction not long after the thing gets going . The smaller trim one like this (pics) has airflow more in step with the exhaust gas flow which is how turbos are supposed to be . Cheers A .

Roy Posted June 26, 2007 Share Posted June 26, 2007 From Clint32's results The turbo has a 0.6 A/R comp housing with a 54mm comp wheel from memory, this was new. The exhaust housing is 0.6a/r with a 58mm wheel, ,aking 235-240rwkws. Does anyone know aything about the HKS T04E turbos that came on the cast wastegates and had the external gate for the RB20? For instance could i use this exhaust housing on a GT3076R.
