hey i wanting to know what turbo convertion would be better for my 25det, a t3/t4 turbo or a T04e turbo. And what supporting mods do i need to do to make this work, eg injecters, bigger fuel pump, boost controller.

x1
really depends what end result your wanting
OR how much $ do you have and then work on it from there

exhaust,downpipe,wastegate,man-
ifold-all gaskets
fuel pump,regulator,injectors-ecu
forward facing plenum,intercooler,piping,BOV
labour+extras like fittings,clamps etc and then tuning

just bolting on should net 220-260ish kw standared internals around 8-10psi

then you got clutch,suspension,wheels and tyres,brake pads,radiator upgrade electric fan,boost controller etc etc

list goes on and on

Saying T3/T4 means nothing at all.

You're doing it wrong. figure out how much power you want, then buy a turbo and supporting mods to suit.

ct9a, Jan 24, 5:58am
hey isnt there ONLY like 50 different t3 t4 combos!

A quote from Mr Murch

Yes he is the one that knows turbos!

1ollie, Jan 24, 6:47am
What power are you aiming for! what does the car get used for the most! untill you know that you can not even get half an idea!

escortmadman, Jan 24, 7:30am
i use my car as a daily, so i would be happy with 300-400hp at the rear wheels on stock internals. my budget for the turbo convertion would be up to 2k. just for the turbo convertion. so thats not including wheels and tyers and suspension.

glenn_michelle, Jan 24, 7:34am
for a daily to have around 500@flywheel on standard internals is asking abit much and a budget of 2k wont get you there,you need all the supporting mods to go along with it,best bet is to stop in at a shop and tell them what you want and ask for a drive in and drive out price and then allow abit more to cover unforseen problems and then you will have a goal to save up for

escortmadman, Jan 24, 7:38am
yea ok, but i wanted to most of the work myself. so if i buy the parts 1 by 1 then a couple of months down the track i can put it all together. i had a mate that did that and it prooved very challenging but very successfull.

OP : Join up to SDU, there are a heap of people there who can tell you exactly what you need to do to get what you want!

thats a different story then,as long as you get the right parts and know what your doing then it should be good,you need to choose a turbo that will reach your desired horsepower and performance at the lowest boost which leaves room for more when needed and budget allows

escortmadman, Jan 24, 7:44am
so would a T3/T4 or T04E type of turbo do the job

1ollie, Jan 24, 7:56am
Standard turbo is good for around 240rwkw with suporting mods an not much more and 15psi max safe boost, standard intake manifold is good for an easy 350rwkw+ before it starts limiting flow, turbo manifold is roughly the same as intake and standard internal motor is good for a reliable 330-370rwkw.

If the motor & other suporting parts are in good condition all you need for a reliable safe 250-280+rwkw(depending on boost pressure & turbo of course) is a 330-370kw(450-500hp) capable turbo(like a Masterpower T56 or Garrett GT3076r or if your game enough try a DSR430) but stay away from cheap T3/T4/T04 stuff on here its just not worth it!, 450-650cc injectors(like FD3S RX7 primarys or Subaru STI ones with collars or the Shred 650cc decaped ones on here), a new Bosch/Walbro 500hp intank fuel pump, 76mm mandrel bent exhaust, 600x300x76 front mount intercooler kit, 38-48mm external wastegate(needs to be Tial, Turbosmart, GFB, Greddy, HKS or similar brand names angain no point relying on rubbish when its one of the main things keeping your motor alive), good pod type air filter and a good ECU & tune like a a Link G4 etc and you will be well sorted! You dont need after market fuel regulators, boost controlers, aftermarket plenums or turbo manifolds for that power level, also factor in a upgraded clutch as the standard on wont last long at this level.

1ollie, Jan 24, 8:01am
2K wont get you anywhere sorry! you need good parts or you will end up spending much much more in the long run trust me as myself an many others have been there before! you need to spend at least $700 on a average turbo or up to $1600 for a good one depending on what you buy! then theres the rest of the stuff

andrea_w, Jan 24, 8:01am
Oh dear. OP, its not about pulling random turbo names out of a hat and asking if that will do. There are SO many variables and I recommend you talk to people with experience. In #1 you asked what other mods you need. with a few examples of what you think you need, that clearly shows a limited knowledge on modifying an RB (no offence intended there). Join SDU forums and start a thread in there. you will get answers from people with many years of RB experience who will tell you what to and what not to do!

1fordluva, Jan 24, 8:02am
good ECU & tune like a a Link G4 etc and you will be well sorted! You dont need after market fuel regulators, boost controlers, aftermarket plenums or turbo manifolds for that power level.

The link has the boost control in the ecu and all you have to do is use a solenoid for vac control.

gtf, Jan 24, 8:05am
Why go straight to the turbo when you've got filter, front pipe, exhaust, boost controller, ecu, intercooler, plugs, fuel pump, dyno tune to do first for a reliable 250-300hp/wheels . maybe then turbo & head gasket upgrades might get you up to 340-370hp/wheels . after that probably engine work.

escortmadman, Jan 24, 8:19am
i was looking at the DSR430. what do you need to fit it to my mota, a modifyed factory manafold of an aftermarket one

1fordluva, Jan 24, 8:20am
The correct oil feed

1ollie, Jan 24, 8:21am
If you got for a DSR430 get a B25 one then all you need is:
1 x 2.75"-3" Silicon Reducer
1 x 3" Straight Silicon Joiners
1 x 2"-2.5" 90 degree joiner ( of Compressor outlet )
1 x 3" 45 Degree alloy ( To pod filter )

then its a bolt up job with a little bit of fiddling like you dont even have to take your manifold off!

jsbike, Jan 24, 8:22am
you're looking at close to $1000 just for a tune on the factory ecu, also as far as i know NZefi in chch are the only ones that are able re-map r33 ecu's. im doing the same as you, and goinf for the same power. costs so far,

rb25det neo $1500
cambelt/idlers/waterpump $280
500cc injectors $500
fuel pump $200
front facing $500
mod to front facing $250
water to air intercooler $400
z32 afm $250
turbo/wastegate/external $1500
exhaust $450

Add that up.

I still need to spend $1000 to tune, and Im sure there a things I have forgotten.

1ollie, Jan 24, 8:22am
Yes and I think you have to drill the banjo oil hole out to 2mm(I think)

escortmadman, Jan 24, 8:23am
sweet. what sort of power gains would i be looking at

1ollie, Jan 24, 8:26am
With jsbike's setup no reason why you wont make 280rwkw with a good tune in it!
