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?

Cheers Fellas

William

you wil have lag, lag, lag.

you will need a retune 100%. just have your stock ecu remapped :D

i dont mind lag lol

but....

will my car be very much driveable still as i wont have enough moeny for remap or ecu before end of this month and i wanna get it mod plated and on road before july 1st lol

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.

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

Forgot to mention turbo has Turbine .63 and Comp .60

Should of done some research but impulse bought :action-smiley-069: but can anyone see any Pro's to this turbo on a rb20det and what would cons be?

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.

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...

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

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 .

Hmm couldn't find much on my quick look. 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. Not to mention cheap:

thats for a externally gated

though aint it?

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.

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 .

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.

    • Seat of the pants assessment of the new intake: The car is way less "doughy" when hitting the loud pedal, especially off idle when stopped or in traffic, I did use a cheapo lazer thermal thingo to measure the temp around where the pod filter got its air, it was between 55 - 60°C, in saying this the car was shut off and not moving, so the OEM intake pipe was not supplying any fresh air to where the pod was when the car was at least moving A weird bonus was induction noise on the throttle in the cabin increased a bit,  I was worried that I was actually going to lose some of that induction noise I love so much, outside though, when I got the daughter to do a WOT drive by pass for me, the induction noise has increased alot when on the throttle, not quite ITB doort, but well up there I'm extremely happy with the results and have been exploring the country roads in the region  As for house mods: 1.New front fence is up and is awesome, it really upgraded how the joint looks from the street, and the added security is nice 2. Electricians have replace some interior lights, and with more lighting in the garage, a few new motion detecting lights out the front above the garage, front room, and at the front door, which I have already found heaps helpful coming and going, also now has fancy pants CCTV all round the house The only hold point for power though is the solar and batteries due to supply issues, although this will happen over the next few weeks 3. I have done a heap of landscaping out the front and I'm almost ready to do a new small retaining wall with some nice blocks to replace the brick and cemented in rocks around the raised garden beds cemented in river stone "was the fashion at the time" the house was built. I currently have a pallet of retaining wall blocks and 2 bulka bags of 20mm blue metal to replace the wood chip that is in the raised garden beds around the house 4. I now have 3 big raised garden beds for out the back to grow some vegetables, about 70cm high, 200cm long and 100cm wide 5. My 2 compost bins are already pretty full with brown, green and kitchen waste from the landscaping I'vedone so far, but they will probably take a few months to break down, so anything else that gets chopped, trimmed, and kitchen waste will just start filling the base of the raised garden beds to about 30cm before I start throwing 40cm of good compost, and stuff, for the vegetables to grow in, I'll need a few ton of compost and soil, but the local supplier can sent me bulka bags of the stuff Basically the logs, wood chips and a few strategically placed rocks for drainage, will give the beds some good organic materials down low to break down over time, and they will hold moisture during the warmer months to save the water in my big arse water tank if we don't get alot of rain So, all in all, the car and house mods are going well, and I'm really enjoying being retired, I sleep in too 0700 and slowly plod around inside until I feel like actually doing anything, and only work in the yard for as long as want, which has actually been alot over the last few weeks,  although when you look at it, it seems that not a huge amount of work has been done,  until I look at the before I started the work pics Happy days and good times indeed 
    • hahaha yeah. Plan is to get side skirts and probably just rear pods. But going to do them one-by-one. I've got a set that I really like from RHDJapen, but that one isn't shipped to AU. So need to find someone who can get it for me
    • Here's an idea, answer the questions I asked you as they are trying to work out WHY the LSD will be binding up in a straight line.
    • You haven't driven many modern cars then have you? Most of them have sfa steering feel with their stupid electric bullshit steering systems.
