Yep, it's call engine swap



.

 

Procharger = fail
Hymee= fail
Turblown= fail
Esmeril = fail
SFR = who knows
RX8 performance = who knows
Greddy = initial fail but great success with the right advice and tuner .

Same story I've been telling you for the last 4 years

 

A few DNA kits where sold locally however, I have not had any feedback from the owners in recent years.

My Hymee kit is running well for the last 2 plus years with several track days since installation

 

Hats off to you for getting to that point - Hymee kit is still a fail though for lots of reasons .

 

Fixed for ya

 

Stuck record much ? lol

Don't be so sure .... My renesis would give your REW a real good run for its money

 

The Hymee kit has a lot of faults but they are fixable we think. The initial design is just mediocre to be honest so it just needs tweaking and certain things just have to be repaired. We are working on that on one of our SARX cars. Only time will tell but with such a limited production run it is really not surprising that it has had so many problems. But I think it has great potential. Look how long it took to get decent results from the Greddy kit. I love my current setup, but of course I am always tweaking (not always a good thing) so only time will tell what the best results will be.

I have heavily researched a few swap options but when it comes down to it, REW's are not that reliable either and when you can make more power you still try and push the limits and therefore end up breaking ****, Especially when it's a daily And I am afraid a piston swap will just make the car less enjoyable even with a substantial bump in HP. But I have not driven a LS swapped RX-8 so I have nothing to base that idea on.

We have a turbo 3 rotor RX-8 locally and it is an absolute beast and the epitome of a well sorted build and if money permitted, I would go 3 rotor.But that would be a while from now. And if I had to do it all over I would go Pettit SC. When I drove Olddraggers car it changed my opinion forever, it was just faster in a NA style sort of way that just made it better than turbo because it drove like an NA with 100 more WHP..

 

Still fail IMO ........ Aside from all the faults ................ You can't buy it !


I guess you could say all the kits i listed can be made to work ..... in the right hands.


As for the pettit - I understand what you are saying , but

When you get your setup over 10psi from 4k rpm through to 8500 ... have another think about it

 

I guess it was rushed to the market without trial so I have had to spend a lot of time and money to get it to its current state. The money pit has dried up so I have to wait around a year before I go for a new motor and experiment again.

For now it is running smoothly so I do not see any reason for it to fail so long as I keep revving it hard and keep the carbon build up at bay.

 

Not everyone is so hard headed ....

 

Yeah - your edit probably sums it up pretty well actually .

 

That would be some fun runs... Until the renesis grenades and cost you more money.


.

 

Yeah I know plenty of FD owners, all of them have blown engines at one point or another. That is just the way of the boosted rotary world. Sure the REW is far more capable than the Renesis but it's not bullet proof at all.

 

I was speaking with a member of the Australian forum and he is getting 326hp at the rear wheels on his boosted renesis with solid corner seals. He used to have a late model modified RX7 and it had less power and reliability.

We also have a couple of converted RX8's in Brisbane and at this stage they are only getting around 300hp at this stage. Sure the older engine can deal with more boost however, reliability suffers

 

and reliability on a boosted renesis doesn't suffer?

 

I don't think there are enough strengthened engines attempting to run more boost .

On stock internals the renesis is only reliable to 7-8psi IMO.

 

Most failures are owner induced in some form or fashion, the avg street ****** enthusiast is generally under funded and under-informed in many regards

Professional builders with fully funded knowledgable owners get better reliability and considerably better power from pre-Renesis motors. Given a choice, they will all choose the earlier engine hands down. All that big doodley talk aside, it's really no contest for those in the know.

Teams on point...... the end/




.

 

yeah - Team knows all about turbo renesis

 

I'm fortunate enough to know a few people that know more than everyone on this forum collectively as a group pit together does.

You think just because you have opened up the load map limit that its the holy grail for Renesis development? This was never any limitation for someone with deep pocket resources such as full-on MoTeC ECU etc. You might as well be in kindergarten as compared to them.

This is what they think of your turbo

 

So owning a turbo renesis makes someone a expert?


.

 

Team knows people


No - of course not . Don't be ridiculous .

 

An expert on pre-Renesis rotary engines no less, the same thing he is trying to play against me

 

RX-8 turbo.

 

I will be keeping an eye on engine development with the likes of Ric Shaw who currently owns the RX8 SP which is raced on a regular basis and probably produces around 400hp. He is also experimenting with various improvements to the renesis platform with some success.

I would assume similar experimentation would be taking place with various other engine builders and over time we will see better numbers.
