That is true, but when you look at a 50trim dynograph taken from a car that used the same dyno as the 35R, things are put into perspective. Its no secret, the GT35R has a MUCH slower spool than smaller turbo's. Thats a fact. It is also a fact it makes less power at lower rpms. That is a fact. It makes bigger numbers but the overall powerband is too peaky to consider it very usable on a real race track.

 

again you have to actually drive or ride in an EVO that has this turbo on it and you will see what I am talking about. its not something you can understand by looking at a dyno sheet.

The powerband is MUCH better then stock, even for daily driving. The stock turbo stops making TQ around 5k, you might be able to maintain that same amount of peak TQ for a few hundered RPM but it will not increase from that point, only decrease.

The human body is very good device for measuring changes in acceleration, but not peak acceleration. So when that stock turbo stops making TQ you are going to feel it.

A larger turbo will keep on making TQ as the RPM climbs, so your body will feel the pull from whatever RPM to smash the gas until you let off the throttle. this give you the sensation of a very broad powerband.

I realize this concept might be something you don't grasp only looking at a dyno sheet and not having any real experience with a 35r. Like I said a few posts above I was ready to be very unsatisfied with my new 'laggy' powerband too, thankfully that didn't happen.

One last thing, how many 35r owners do you hear complaining about their powerband, the answer: ZERO. I think that says it all. If you still don't believe me then go drive one and see if it doesn't change your mind, I know it did for me.

 

A LOT of them that are on the stock 2.0L. It seems a lot of the early 35r crowd now has built 2.3L's. It's a pretty proven formula; and one I'd personally love to have if I had the cash to throw.

If you're going to run straight pump on the stock 2.0L - don't get a 35r. I think that's my advice. If you are doing racegas or are working towards a built 2.3L; then it's definitely a good option.

And for the record; I've been in a few GT35r's with the stock 2.0 and pump gas. Lag until it gets to about 4800rpms. That's almost dangerous for daily driving. But man... once that hits!

 

I went from 35r to 30r and will never look back.Try pulling into traffic with a 35r, pushing the gas pedal and waiting for spool.It can be downright dangerous.With my 35r i rarely used 5th gear,but with the 30r all gears are useable.30r is much more urban friendly.I wouldnt consider a 35r again without a 2.3 or 2.4 block.If your evo is a weekend car it may work for you,but i prefer to drive mine anytime anywhere without compromise.

 

You keep telling yourself that

 

its all about power under the curve.

I love my AMS bb 50trim. I run it on straight pumpgas with a conservative roadrace tune and the car is more fun than anything in the world on the street.

I considered the 35r before and decided that easily the best bet is to get the 50trim for now and if I ever plan on building the motor I would go with a 2.3 stroker and then possibly swap to a 35r. I would much rather have a strong powerband than something really peaky with great numbers.

 

Again I ring my car out, so thats why I got a 35r. I LOVE IT. 3deep, what you are talking about in traffic that happened to me in my 3076 and stock turbo no lie.

 

different strokes for different folks I guess. But anyone who tries to merge in traffic w/o downshifting, regardless if they have a stock turbo or 35r is an idiot and the reason I have to use my horn.

 

haha tru

 

This is kind of off topic, but until large turbos come with variable turbine geometry as a standard feature, I'll will never run a huge turbo on a small displacement motor like the 4G63. Everyone is different I guess, but coming from a V8 backround, I don't like to wait for my power. If you're heading into a corner and you are at 7000pms, and but need to slow down, you hit the brakes and end up and 3700 rpms. If you try to accelerate out of out of the turn with a laggy turbo without downshifting you will bog. You will be forced to downshift with a laggy turbo where the guy with a 50trim can just accelerate through the turn without having to change gears (he doesn't have to wait for the turbo to kick in) and hence he will round the corner FASTER than the car equipped with the big laggy turbo. On the straights the 50 trim will get murdered by the larger turbo car, but in general I think its more desirable to have a setup that will enable higher cornering speeds.

 

Very true....^^^^^^^^^^, but a 35R is a great track turbo with a stroker. Hence AMS, Crawford, and Topspeed all using 35R's.

 

The 35R seems more feasible on a stroker, but I keep seeing all these kids with 2.0's with the 35R, just makes me want to smack them.

 

not to be antagonistic, but if lag is so OVERATED, why aren't you running a GT42R?

 

just get the 30r!!, bigger than 50 trim which has fast spool, but smaller than 35 which has lots of power, so the middle, is the 35r, a little of both, im on the other hand getting the 50 trim because im a daily driver and and wanna run a safe 22 psi daily driving and not worry about blowin the block

 

i can get you a 35R kit from slowmototrsports for low 3000$... i made over 500 awhp on there 35R kit.
