All I have to say is that I know RnR's customer service is awsome and I have their o2 eliminator DP so I can also vouch for their workmanship. I think that I may be down for one of the kits, and hell, as long as you are going this far you might as well go all out with the bling, bling serious HP. Unfortuanatlly I would deffinatly have to wait until March or so since X-mas is coming up (HUGE family) and I am buying a house in Feb. However, shortly after that I would love to add some of the serious ****. Have you guys done your testing with the stock cams or aftermarket? Would some different cams help with the big turbo options?

 

what are the headers going to be made of hopefully cast! another thing would it be possible to custom a kit with a gt40 for me = P , i also like the tail waste gate etc etc bling bling setup more power = bigger smile for me = )

 

Big cams will defintely help with a big turbo. Also we will be doing all the testing with HKS cams since they are already in the car.

We can do a kit with a GT40R. We will have our 3 levels on regular t3/t4's and also on GT series dual ball bearing turbos.

We can do whatever turbo you want. We are just having the 3 levels for both series so if you don't know a lot about turbo combos then you won't have to guess at what will work right for your EVO.

 

so back to the original question are the headers cast or are they tubular ? that might be a weakness if it is prone to cracks and such , but if you offer a warrenty with your tubulars like somecompanys i might just be willing to risk it = )

 

so can we run this turbo set up with 91octane???
and do you guys have any internal modifications that we can purchase as well?

 

you can run any turbo on 91 octane....RnR uses cast steel elbows welded to make a tubular manifold thats most strong and extremely high flowing.

 

yes, we use cast stainless steel elbows that are very very strong. We also use expeansion slots for the stainless. We do offer a 3 year warranty.

We have never had one of our manifolds crack and we have built a lot of them.

We can use 91 octane and you don't need any internal modifications at all.

 

I am definitely down with the bling bling high horsepower. I will most certainly go with one in the future from RnR.

 

would you recommend gettin some internal mods just to be on the safe side?...or is it absolutely not necessary

 

Stronger internals are always a plus for reliability... Especially if you're pushing significantly more air through than stock.

However, if you get a good tune and stay away from bad gas, you should be fine to a certain extent.

 

It all depends on power. If your only making 450 hp on race gas, I would say your far more likely to had your new engine die because of bad machine work then have it blow...I think the limit where it become worth while is about 450 whp....below that its simply not nessecary.

 

Not to be an ****, but what's the point of posting dyno numbers based on race gas? The last time I checked, the gas station I filled up at was 93 octane at the most. I don't plan on building up the car so I have to buy race gas everyday.

My last car (Vortech Supercharged '99 Si) ran great on pump gas at 293hp and obviously ran much better tuned to race gas at 322hp. I only used race gas twice in that car and put 45,000 supercharged miles on pump gas.

My point is, you already have a great reputation so just entice us with reality. You're only as strong as your weakest link and most of our (owners) weak link is we can't always get or afford race gas.

Like I said before, not be an ****. I just like to know what I'm getting on the street so on my next traffic light encounter or highway rundown, I know what I'm playing with.

 

The beauty of a turbo system over a supercharger system is that I can run 20 psi on 94 octane pump gas all day every day making 300 HP, and then when I want to go to the track pull off the cat, and dump in some leaded race gas allowing me to raise boost to 24 psi and have a hell of a lot more power. I do understand your point though, I like to see both pump gas and race gas dyno sheets for any setup I consider purchasing.

after 350 whp you start having trouble with 91 octance on any turbo....you upgrade to a 50 trim and get 360 on pump and 420 on race....then you upgrade to a 60-1 and get 400 on pump and 480 on race....then you upgrade to a gt35R and make 430 on pump.....and 600 on race...

 

The realiy of it is that most of us are going to be filling up with pump gas everyday. That is why we are using real good pump gas turbos.


If you want a lot of power on 91-93 octance I would suggest our level 2 or 3 turbo kits. Level 3 being the best choice for power. I would also suggest our dual ballbearing option as that will enable you to use a large turbo and still spool pretty quick on the street.

The bigger the turbo the easier it is going to be to make big power on pump gas everyday.


The only internal mod I would suggest doing is ARP head studs. That will keep you from blowing the head gasket.
