if you wait till after march 1st ill let ya know how the SBR kit goes. its complete and with injectors is still less than the peak boost kit btw. the good thing about the sbr kit is the WG dump comes pre routed into the 02. just bolt it up. no going open dump or paying a muffler shop another 100+ $(big no no where i live). ill post up dyno #'s after my tune in march. good luck.

 

How do you say 5-6 hp difference in turbo kits. You cant say that, it all depends on tuning and how conservative the tuner wants to be. 1 degree in timing can = much more than 5-6 hp.. Sure the hardware is the same, turbo is same, but manifolds flow different. There is no way you can justify 5-6 hp diff. This is not an all motor car in which you can say 1 part typically makes a certain hp level.

 

I said RNR GT35r is one of the best for the money. I have it on my car for more than a year already and did lot of drag and 2 tracks with it (on different tuning as well). I beleive it's less than $3500 currently. Here are some facts for you to consider:

1) 410 whp on dynojet with a conservative tune (22 psi) by Tuning Technologies with SAFC and ECU+ in which ECU+ getting more power and torque in midrange.
2) 530 whp on C16 on the same day with 28 psi.
3) Reliable proven. It has been on my car for more than a year and I did full it off, put it together a couple times due to some run-into-the-law problem. I'm also drilled a hole into the manifold for EGT and it won't crack.
4) With my granny shifting, I was only getting 12.2 but 123 mph trap.

I saw Smogrunner AMS kit and it's a beautiful kit as well.

 

Honestly, if you are a man worried abuot money just check the forums everyday and jump on a used kit. You will save 1500-2000 like this and get the same thing, with the nature of the parts they don't really get much wear and tear....maybe the turbo, but it should outlast the motor in most situations.

I have been waiting on a used kit for a while now and finally came across a RNR kit. I am in the process of installing now, but from the looks the kit seems to be really nice....and their manifolds come with a lifetime warranty for cracking.

Unless you have a build motor and plan on running TONS and TONS of boost, i don't think the difference between any of the kits(ams, RNR, full-race, etc) will really shine through.

you know what they say about opinions, they are like a$$-holes...everyone has one. So take all opinions with a grain of salt, including mine.

 

now there is some good advice.. ^^^ lastly you might want to check out turbo trix new turbo kit.. its not a 35r but it puts some good numbers, and a decent price..

 

What about the ATP GT35R Kit, I mean it has got to be one of the lower costing kits out there, but how does it perform?

The kit hardware will consist of the following:
Garrett Prototype GT Ball Bearing turbo w/ATP Proprietary Housing with GT inspired High-Flowing Valute
Bolt-in design retains stock manifold - Retains stock heatshield for OEM appearance
Steel braided lines and fittings for oil/coolant connections
Tial 38mm External Wastegate
Stainless wastegate discharge tube with downpipe re-route
Silicone connectors and clamps
All mounting hardware, gaskets and CNC machined fittings
3.0" Stainless steel downpipe w/stainless O2 housing
100% bolt-on design. No welding, cutting, or fabrication

Price around $2,700

 

Buschur's Kit is only $2,999, that's a damn good price from a respectable EVO tuner.

 

Or you can just buy the turbine housing from them and then just piece one together. ATP is the one with the wastegate flange on the turbine housing correct??

 

Tuning is paramount etc etc the bottom line is a 35R will top out at around 650awhp...Buschur trapped 141mph, CBRE trapped 140, Dan trapped 139mph etc etc in the end they are all about the same just like Trinababe said.

Buschur for 3K is definately worth it IMO and AMS's 35R is not worth $1500 more the end result in traps are very equal. AMS's is prettier though, so is Full-Race, and Turbotrix etc etc.

 

ATP has a gt35 kit that is about $1500 cheaper than AMS bcuz it uses your stock ex manifold. it won't make as much power as the AMS but it is cheaper. i would also look at the Greddy 25G kit. get the one with the 10.0 hotside & then upgrade to the 14.0 hotside. u won't regret it. the Buschur 20G upgrade is a great bargain as well.

 

Would like to chime in on what our kit includes.

Cast manifold that we designed, it is ceramic coated when you get it.
GT3582, Garrett Ballbearing turbo charger
We use a special turbine housing on our kits that have an integrated port for the 44mm Tial external wastegate.
Tial 44 mm external gate WITH all SS v-band clamps AND the special leaded fuel seat.
SS 02 housing
SS dump tube for the wastegate
Oil feed and return lines

The kit can use the stock heat shield if you choose to make it very stealthy or our SS polished heat shield fits too.

The kit is $2995.

Our black shop EVO ran a 10.12 at 141 mph with this exact kit on it, our full 3" exhaust and only 32-33 psi of boost. The kit will make 21 psi of boost at 4500 rpm on a STOCK 2 liter EVO with a STOCK head, stock throttle body and stock intake manifold. This was recently confirmed and done on a car that is still here using the AEM and the AEM controlling boost.

I don't think our kit can be beat for reliability, cost and performance. I am sure I am biased

As for the steel being used, yes it is sometimes different yet has anyone actually cracked one yet? Same goes with the support for the turbo... anyone cracked a header yet? I guess i never looked into much about clearing the radiator hoses as I assumed almost all of the said kits would fit it fine. As for the turbo being used.... what other version of the GT35R does anyone use? I was under the impression they all used a GT35R .63 AR (Some use the .82) with the S Cover. There is no difference from one GT35R to another. Some of them may drill holes in the compressor cover (Which you could do yourself if you really wanted or pay someone $20 to do it for you). You could also tell the vendor which version of the turbo you want as it would not cost you anymore... they all would cost the same.

Since everyone agrees on the only difference in the kits really being the header, Shearer is probably the best at making headers for us from all those vendors. But since i dont know what Im talking about you should ask Big Al from Dynoflash... many people like/trust him. Find out who is making his kit for him. Ron Shearer. If you dont want to screw around and honestly want some of the best stuff out there go with Shearer. If you want something that is in stock, sitting on a shelf and lots of people run it, go with one of the other kits.


Dave, is the special hotside you use from Forced Performance? Like the ones for the FP3052, 3065, or 3575?

 

Pm Peakboost ken for the prices..

 

Its going on the dyno this friday and I will post up a dyno sheet and a video for everyone so everyone can see how peakboost kit compares to the rest.

 

For the price I don't think our kit can be beat as far as quality, fitment and performance goes. Especially when we run group buys.
