Hey guys,

Im sure you have seen this question a million times but I would like to hear peoples opinions on the best turbo for my application! Ive done lots of reading over the last few weeks and have looked at so many different dyno sheets... Long story short, ive got a built 2.0 stock compression, gsc s2 cams, precision 1000cc injectors and walbro 255 plus all the bolt ons like i/c, i/m, t/b... I purchased an fp black with manifold and o2 dump a few months back, but after briefly talking with Tom from tscomp and a few other people I have come to the conclusion that I will probably come up short on my goal of 500hp on pump 94. I know that 94 is the limiting factor here and I understand that. Unfortunatly thats all we have here in Canada... I have listed the black for sale and am looking into a t3 setup of some sort. My question is, what is the best all around t3 turbo for a 2.0L? I dont want something ridiculously laggy and would like to make 550ish hp on pump. I had an HTA3586 on my last built 2.0 and thought the turbo was pretty laggy. Right now ive got it narrowed down to a precision 6262, 6266 or gtx3582 and want to pick up a complete kit. So far I like the ETS and MAP kits the best and they are decently priced. I want a fun street car and will be shooting for a 10 sec pass this season. What turbo would you recommend and why? Is twin scroll worth the extra $$? As for my fuel setup will it be sufficient for pump gas? Should I go to something like FIC 1450's and a walbro 400lph to be safe? Any opinions are greatly appreciated!

 

I've been inlove with the 6262... Probably the best all around turbo in my eyes... My next project is either supercharged 2.4lr or 2.1lr with a 6262...

 

whether it's worth the money, is for you to decide. but generally speaking, a twin scroll is far superior to a single scroll. much like a naturally aspirated motor, optimizing exhaust flow is key. which is why so many people go with long tube headers when they want to make power. with a divided housing turbo, you'll need to get a divided manifold as well. basically, it will take exhaust from alternating cylinders in the firing order and combined them in to one. for example, Honda firing order is 1-3-4-2, so it would combined cylinder 1 and 4, and 3 and 2. the purpose of this is to allow the exhaust gas to escape freely without being interrupted and bottlenecked by the exhaust from the next cylinder. this will greatly improve spooling, especially on a bigger turbo. which will allow you to hit your goal with a larger turbo, an not have to be so concerned about lag.

 

So what turbo would you recommend with a TS setup?

 

a black would do 500 on pump, a 6262 will do 6-700 easy

 

I don't believe the 6262 or the 6266 are made in divided housing t3 flange, only t4. regardless, you'll have to get a divided manifold either way, so the flange isn't too critical. I would go with a 6262. it's plenty capable of 650+, which will give you room late on if you decided to do water/meth.

 

Most of the dyno threads ive seen were making low to mid 500's on the 6262 on pump 93

 

Nah dont think so. All the ones I seen over 500 were running C16 or E85. Since OP doesnt have access to high octane fuel, I believe a 6262 or similiar will net 500whp @ 94 octane.

And ah, I see you had a 35R before. Unfortunately they become very laggy beyond this point. Because of that, most have been teaming MHI/T3 turbos with E85 for maximum output. Is meth injection possible? A 2.3L would fix lag...

 

I ran meth in my last car and made better power. I'm trying to keep this setup a little more simple and would prefer not to run meth.

 

Wrong! Twin Scroll T3/ T4 set ups on are cars suck ***. They do NOT make any more power then a standered single scroll set up, theres a reason why buschur and STM dont run them. If you want 500hp on 94 octane which is doable I would do a precision 6466 or forced performance GT35 HTA 86. Problem is I can almost promise you a Meth car with a FPRED will pull hard on you untill you hit 5th gear.

 

Yah know I just realized youve already had an HTA86 lol my bad man. yeah they are laggy and honestly so is the 6466, thats the limiting factor with a 2.0 liter man. this sounds crazy and just bare with me on this but what about a compound set up? Is money isnt a factor its not expensive to do and rather easy if you already have a tubular manifold. I know of a few people on the DSM forums that have done it with great success. You can pick up a WRX TD04 turbo rather cheap or a DSM T25 feed that into a 3586 or a precision 6466 and you will have awesome spool up and the power you want. Im telling yah its just so crazy it will work!

 

LoL no compound setups for me. I am on a student budget. How does the 6466 spool compared to a 3586??

 

Ive had a lot of people reccommend the 6466. What kind of spool can I expect from this turbo on a 2.0? What kind of power difference is there between the 6266 and 6466? Would going twin scroll be worth the extra $$?
