That is the most ludacris thing I've ever heard. The Garret ball bearing CHRA is probably the toughest and most dependable center section I've come across in my entire life. I bet these turbos will outlast anything made. I've seen more stock Evo 8 turbos fail than GT35R's.

Ok OK. That is why I posed this question. this was in '98 or so I was told this. I will take your word on that, as noone else came up to confirm or deny it. Thanks.

I have the fullrace stuff and it is top notch. things to look for in turbo kits are the shape of the collector and the downpipe. most kits out there lack in this area. I've never heard of a fullrace mani ever cracking also.

1. Cracking is an issue only with poorly constructed and poorly designed manifolds. A high quality thickwall manifold has the ability to outlast your car. One thing to keep in mind is that not all tubular manifolds will perform equally, there are many designs considerations to take into account.

2. your SAAB turbo guru is probably used to older style bushing journal turbos like Turbonetics or some off-name brand. The garrett GT series turbos are extremely high quality and exceptionally durable. There will is no need to freshen this turbo unless you have catastrophic failure.

Yes, it works quite well. Upgraded camshafts are an excellent idea.

4. new manifold, new downpipe, new wastegate

5. no need to aid spool if the turbo kit is setup properly. A good Gt35R turbo kit will spool VERY quickly. A stroker kit is the best way to spool a turbo faster, however this is not cheap.

I actually disagree slightly with this. The GT35R is definately very efficient at high boost levels, however it also works extremely well at low boost levels, too. We have seen cars make great power from 10 psi to 35 psi.

Also, if you are looking to make more power at all boost levels, we offer an exclusive turbo called the FR GT3567R. This is a gt35R center section, turbine wheel and housing with a T67 compressor wheel. This combination spools like a GT35R but makes the power of our T3/T67 HO.

One more note, if the turbo/engine are setup perfectly, with a good intake manifold (unfortunately i havent seen many of these yet) and properly degreed cams/cam gears, you can make HUGE power with very little timing. The less timing the better, as cylinder pressure is what destroys motors.

If the car is built perfectly, adding timing does not make more power, it simply increases cylinder pressure (hurts the motor). C16 is a great idea at high boost, regardless of timing, but in all actuality, if the car is perfectly tuned, more timing will not make more power.

Answers:
3. Yes, me, except I run HKS 272 cams.
5. Obviously, the stroker kit is way better for daily driving than Nitrous. However, it didn't seem economical to me. I'm still recovering financially from the build.

Hey Smogger,

Good to see you are still around, I thought you got rid of your evo. I dont think the stroker would be worth it, but then again, maybe its time to freshen the pistons, as I am close to 55K miles now. dont know which way to go if I track it monthly, and street drive the rest. I am not looking to Drag, just roadcourses. Thanks for the input!

Full Race kit is rather nice. However, can you select certain parts? Or are you obliged to buy whole kit?

Also, how streetable is the gt35, and how much of a risk does it pose to stock internals on pump?

you can buy individual parts also.the 35r is very streetable, nothing like i though it would be. I will never go back thats for sure!

Not to be a d---, but if you can show me an Evo with a GT35R making "great power" at 10 psi, I'll eat the whole car bumper to bumper.

I run a very conservative "street tune". I'm not sure what you consider a "perfect setup" but I will tell you that when I go to the strip and run c16, I can add timing and make more power.

What turbo IS going to make great power at 10 psi?

I'm sure there is someplace, but not on an EVO!

Actually Scionspeed threw a GT35 on a Scion tC and made over 300 whp at around 10-12 psi. The car had stock internals and it still managed to run a low 12 second 1/4 mile. But I think they ran it on 16 psi for that run. It's in one of the issues of Modified Mag.
