gt35r vs. t3/t4

Its just a difference in the flange size, the exhaust wheels and A/R options are all the same as far as I know. The T4 flange will outflow the T3 (it's larger, duh) but that shouldnt be an issue with a 35R.

 

 

Edit, Woops, I thought you wanted to know the difference between the T4 and T3 flanged gt30r.

I plan on getting the 35r becuase of its top end performance. I didnt know where the t3/t4 fell into. It seemed like on ebay they where saying the two are the same. I am just clearing it up for me and wondering whats whats.

t3/t4 is a very broad term for any turbo that uses a t3 exhaust flange and a t4 compressor side. u need to find specific turbo measurements for anyone to give u a comparison worth anything. gt35r's come with both a t3 exhaust side or a t4 depending on what u order and i believe there will soon be a twin scroll t4 gt35r. do not buy a turbo off ebay if it just says t3/t4, thats just standard ebay garbage. look up AMSperformance.com they have some of the best stuff for evo's, them and buschur which i see u already know. i believe someone around here made 500+ whp on a stock engine evo with a gt3582r (i think)

So a gt35r can basically be a t3/t4 turbo? t3/t4 are just the measurements? I hate the lag in my stock one and I can get a t3/t4 for a good deal. Thats why I wanted to see the similarities. To me it sounds like gt35r is a turbo and t3/t4 are just measurements of one.

gt35r will be way more laggy than ur stock unit. turbos are a trade off of lag for top end so if u want good top end u will have to deal with some lag first. if u want almost instant boost u will have to have a smaller turbo which will fall off top end. with that said there are some set ups that do both better than others. for example i run a 60-1 t3/t4 by turbonetics, nothin special but fairly good sized turbo. i made 502whp at 8300 rpm but i have to wait till about 4000rpm to get full boost. had i gone with a smaller turbo such as the greddy kit for my car which uses a 14g mitsu turbo like the stock evo just a little smaller i could have full boost at between 2500 and 3000rpm but couldnt make much more than 315 whp.

Guest v8_What?

gt35r is not as laggy as you guys might think!! Mine is nowhere as bad as my greddy TD-06 20G I had on my 180sx over in japan. When my evo is done at slomo I will post some graph for you guys!!!

 

And if you really want to see some lag let me know and I will post up some of my dyno graphs from over in Japan when we were shitting around and put a T-51R KAI on my sr20det. Boy was that some laggy but dynoed at around 576 if I remember correctly. I would have to go searching for that one!!! MAN I miss my Japan days!!!....hmmmmmmmmmmmmm

For that goal get a ported IX turbo.

 

A 35r will be barely in it's efficiency range with 350 dynojet whp

 

What is your trap speed and et goal?

 

 

I would agree with this. You are going to have a hard time keeping in that power range with a 35r. low safe tunes for the evo usually hit in the 420's to 440's .

 

If you really want to stay in the range I would recommend a gt30R or a FP Green. Their are guys on EVOM running 10's on both those turbine. the 30r has a good top end range that you are looking for!!!

If you want a turbo that will preform its best on pump gas and make 400awhp get a Garrett GT3076R. I had it on my SRT-4 and my buddy has it on his Evo 8 and he made 415awhp on 21psi pump gas. The Evo 8 stock turbo is not bad but you can make 350-375awhp on it. DO NOT GET AN FP GREEN unless you wanna waste money and make no power on pump gas. That turbo makes about 3-5whp/psi boost on anything above 15psi.

Is the fp green the same thing as their 3065?

The fp 3582 HTA turbo may be the best thing going for evo's. Hopefully they make a wheel like that for a pt67. It is however a 4 bones upgrade.

if all you want is 400 wheel, I would just get cams, and maybe meth injection if you choose not to run good gas. 35r is going to be more of a 500 hp range turbo, (actully more depending on the A/R an such you choose.)

 

We just installed an tuned an evo with cosworth 272s springs retainers, walbaro aem meth kit, and a couple of small things and at like 24 pounds of boost made 395 whp on our dynojet which reads very conservative. (so just from a comparison sake)
