...could you please tell me why you're going so unbelievably overkill for a measly 7 - 10 psi?? that turbo seems a might bit big, along with most of the other stuff...

 

If people are interested in smaller setup, we will offer that as well. But a good effiecient turbo will make 350whp at 10 psi no problem. On the intercooler, we do not want any detonation issues, so the bigger intercooler will take of that.

...right. the thing is that the T04R isn't very efficient at such a low flow rate (that turbo hits its stride well into the mid-to-high teens, up to the low 20's... i know), not to mention i'm sure you're doing this for the 6 port motor (which doesn't have the better flow characteristics of the 4 port), and this turbo has a 0.96 (completely overkill for those power levels, and underspoolin' for around town) A/R ratio.

and also, why are you sourcing an HKS turbo when it's just another Garrett clone?? can you get them cheaper than other American makes (like T'netics and whoever else)??

 

The pictures are with the HKS, the turbo will be Garrett

That was true up until the Renesis. The new 4 port engine is not even close to the intake port timing or intake runner area of the last 4 port engines. The 6 port Renesis is the better choice for turbocharging while the 4 port 13B is a better choice.

 

For a moderate power increase up to but not over about 350 hp on the stock engine I would favor a T-04B instead. Size is nothing witout efficiency. Even a 60-1 HiFi could put out 425 rwhp at only 15 psi and it is much smaller than the T-04R. Efficiency is everything.

 

We will be trying out several turbos

Some people have asked us for big turbos, that will allow them to run 20 psi. Some other people want to stay under 10 psi.

So we are still deciding on the turbo setups.

When do you think the project will be finished and we will see some dyno numbers. i am also interested to see the price for the kit and price of installation

 

I am getting my built Evo engine this week, so the RX8 is going for the manifold next week. Give us at most a month.
The price estimate should be done after we settle on a turbo.

- Tial 40m silver wastegate, plumbed back to the downpipe
- Stainless steel 3.5" downpipe
- equal length SS exhaust manifold
- Blitz intake filter
- hardware and oil lines

Turbo kit #2:
- HKS T04Z ball bearing turbo, with .61 AR housing , 4"mm inlet pipe, 2.5" compressor outlet pipe, 3.5" downpipe
- HKS Racing SS wastegate, plumbed back to the downpipe
- Stainless steel 3.5" downpipe
- equal length SS exhaust manifold
- HKS 200mm intake filter
- hardware and oil lines


Intercooler kit#1:
- Spearco (or PWR) intercooler , 24"x8"x3.5"
- all polished aluminum piping, with choice of red, blue, black connectors
- blowoff valve flange ( customers choice)
- HKS SSQV, Greddy Type S, or Blitz Super Sound blowoff valve included


Intercooler kit#2:
- HKS intercooler , 600x244x65mm, Type S core with polished endtanks
- all polished aluminum piping, with blue HKS connectors

Fuel system
- upgraded secondary injectors
- upgraded fuel pump ( Walbro)

Here are some pictures:
- The HKS T04Z ball-bearing turbo


- the HKS intercooler ( piping will be diferent)


- the Garrett T04R turbo

 

prices?

 

It all depends on the manifold, that is the key in the whole buildup
We do not want to throw a number now, and then change it because the manifold was a lot more expensive.

 

will it work for automatics?

 

We are testing it on a 6 speed first. After it is tested there, we will try it on an auto. But the ARs on the turbos will be smaller:-)

 

i'll take what i can get

 

when will it be out?

 

dude...are you guys near Suwanee? i have to go up there this week and would love to drop by...
