i have a question, what is the difference between a t04e and a t04b? i can buy a t04b but it supports up to 450 hp at 30 psi. what is needed in a single turbo conv.
please tell me in a list. i already have
1.intercooler
2.all pipes can be purchased
3.i have single turbo headers from obx
4. i have a bov

i know i need a wastegate and what are the other small parts i need. i want to know what i will need for the oil cooling lines? i got this stuff seprate and i am going to buy a turbo only cartridge. i need to know where i can get the other stuff from? please help!!!
also, how many psi does my motor need to have in order for it to work for about 15-25 psi of boost, and overall how many psi of noost does my engine need for compression to not need a rebuild?


thanks for any help

 

I have been told that the T04b can not take the heat from a rotary.

I think the diff is the T04E has a clipped wheel which is more efficient. The B is apparently and older design probably 20+ years old.

Someone correct me if i'm wrong.

 

yeah the to4b is old school XP. it wasn't meant to be on rotary. i almost forgot there was such a thing.

 

Alot of people run To4B turbos.. Nothing really wrong with them they are just smaller ..


And dont expect to run 30PSI on pump gas, case you dont know. And it wont make 450RWHP.. plus you need to know the specs of the turbo to see if it even is a good match for a rotary.

Given the 450HP claim, i'm guessing this is one off of eBay.

There are two models floating around:

.60 compressor, 1.00 divided
and
.60 compressor, 1.15 divided

 

T04B's are great turbo's ... where's the love? Lots of people have done over 400 at the wheels on them, Brian Cain for example did 422 with the exact same turbo I have at 15psi. 60-1 HiFi, .96 A/R Tangential undivided.

You can make plenty of power with little to no lag, not to mention you can find T04B's dirt cheap.

 

like these?

How much should one expect to pay for these types of turbos? Seems like that second one has a pretty high exh side ratio. 1.32... Still need to learn more myself on how and what to pick as far as that goes.

 

The T04B is probably the most common turbo used on rotaries. I have owned both a T04E and 60-1 T04B. The 60-1 T04B definitely flows more air. From looking at the description on Ebay, it doesn't look like this is a 60-1. I would say the one on Ebay is capable of around 360 HP to the wheels. I wouldn't expect this turbo to be very efficient anywhere above 15-17 psi. You can go to the turbonetics and innovative turbo websites to get a good idea of what one of these turbos is worth. My guess is around $700 new.

 

How can you "tell" what a 60-1 looks like, just out of curiousity.

 

I can't. The 60-1 is the type of compressor. The compressor is hidden under the compressor housing. From the outside I believe the turbos look the same. It costs extra for a 60-1 compressor wheel so if one of these turbos had this type of wheel, it would probably be mentioned in the description.

 

Can't take the heat? Where's your source of information?

T04B turbos are great for street and strip.
The 1.15 hot side will yield great lag. I had 0.96 and 1.15. 1.15 had more top end power, but it took longer to hit full boost.

I never got to dyno my 1.15 set-up with the updated tuned maps. BDC thought it felt pretty good.
At 6krpm, it slams you back pretty good =)

What kind of intake side should we be looking for? Seems like a lot of these are .60 (IIRC).

 

I've asked around before i bought my turbo and even turbonetics suggested the T04B turbo.

So I hope this is not 20+ old design. I assumed it had all the new designs etc.

I have the T04B .96A/R .70 Trim 4"inducer.

I am using a T04B 60-1 compressor with .7 A/R front and 1.00 A/R rear housing. So far I am very happy with the spool up and top end.

 

Isn't that considered a T04S (60-1 with .70 housing)?

 

XS Engineering has a T04S which is supposedly a 60-1 with .7/1.00. So to answer your question... yes.

 

I thought the TO4S was a TO4E based turbo.. but not 100% sure..

 

From what I have been reading it has a 60-1 compressor wheel. I have never heard of anyone putting a 60-1 wheel in a T04E. I'm not saying it can't be done but every 60-1 that I know of uses a T04B housing.

 

As I understand it, the TO4E is a just a new version of the to4b, with a larger frame to accomodate larger wheels.. And the t-series aftermarket turbo's are of course based on the T04E because it can accomodate a larger wheel and has the inlet size to do so..


Here is a breakdown of turbo sizes and specs so people can see for themselves it if helps..Max

I have a FC and I am using a T04B unit with comp. 60 A/R and 55mm wheel and turb. 1.00 A/R and 65 mm wheel. Sorry about the specs in mm but I live in Greece and we are using these measures. I've been told that I'll pass the 300hp mark at 15 psi, do you agree?
George

 

To those that don't think the TO4B won't work on a rotary, you obviously don't know much about turbocharging rotaries. I enjoy my TO4B.

 

15psi on a To4B should give you more than 300 hp...

 

Dam if a To4B was only 300hp i'm sending mine back!!!!!!!!

Seriously like eViLRotor says it will produce lots more then that!!!!!!

Ian
Going to be Wayyyyyyyyyyy faster then eViLRotor "AKA Mr. KKK"

 

eViLRotor and IAN you just made me a very very happy man!!! Now, all I have to do is to find 2ndary injectors to feed it...
Thanks guys !!!!!!!
