Yea I will def be going BB. Im trying to figure out what the spool difference is between the 6266 and 6466. I don't want something super laggy because the car will be primarily street driven. My biggest worry is a very laggy turbo especially because im limited to pump 94 oct.

 

if you are ok with a 6266 i cant see you being unhappy with a 6466. but IMO if your stuck to 94oct then you will want the best overall power band. i would choose the 6266. are you going twin scroll or no?

 

I was looking into twinscroll but don't know if I can justify the extra $. Will spool improve all that much? Will top end be affected?

 

check out my for sale thread i am selling my TS kit minus turbo. IF setup right no it will not hurt topend. my street car on 6466 trapped 151. i dont see that hurting topend..will it spoolup faster? HA your in for a treat. yes. a lot sooner ''also if setup correctly''

the only down side to twin scroll kits IMO are cost. and if you go cheap you will get cheap and be unhappy. if you do it right then you will get what your looking for.

 

Yea ive looked at your kit quite a few times lol. I think im going to keep it simple and do a basic t3 6266. Im hoping I can make 550whp with my supporting mods. Are all precision 6266 Billet CEA or is that an upgrade?? Also what cover would I go with?

 

all 6266 are CEA.

 

Ok sounds good. What about the cover? Theres a few to choose from?

 

get the 4.0 inlet anti surge. with 2.5 outlet.

 

Ok thanks a lot for your help! greatly appreciated.

 

Cheers Dan good info for everyone

 

I'm seeing too many oiling issues with the PTE units, to a point in which I highly question their reliability compared to a Garrett-based ball-bearing unit. The design of the exhaust wheel in either divided or T3 standard housings is miles above response between gears as opposed to the PTE unit. If you're going to spend that kind of money, for your options, its best to stay with a reliable water-cooled cartridge.

Ask yourself this question. Do you run your car engine to 7000rpms without a radiator? No? Then why run a turbocharger that's running over 120,000rpms without it either? Remember the purpose of water.. to dissipate heat from the rigors of use on an Evolution, which is an engine platform that likes to utilize higher rotational speeds.

Do as you will, but I think it will be a costly error in the long run.

 

Um most of the fastest evos use PTE turbos. And the ones with oiling issues is user error imo. Not having a proper line, not having proper oil pressure in the head/line, not having the proper fitting on the turbo. Pte puts proper fittings on or will sell you the right one. Most either remove what is there or do not use the right one or one at all.

Garrett is great and I like the water cooled options. I agree that is a bonus but not needed.

 

evodan,

I am on an AMS 50 Trim now maxxed out at around 492-496 AWHP on a 2.0L block and I am content with how the car spools now on the street although its not like the stock turbo.

If I went to a built 2.0LR block with a 6466 with 93 + meth with the right setup and combo of parts will it feel sluggish and boring on the streets compared to the 50 trim set up? I know that once the turbo starts spooling at 4800 or so things will get interesting, but at around 3000-4800 RPM's will the car be totally sluggish and boring?

If I go this route I also plan to tune for E85 as well for days I may want to run in "kill mode" but for daily driving, I'll do 93 +meth


Thanks for your insight.

 

You have been on that 50 trim since I was on stock turbo. Lol I believe we started to build are kits and ideas around the same time. Honestly the 50 trim is old school imo. The newer pte, gtx turbos are amazing. I would bet to say a 6262 CEA would spool about the same as your 50 trim but make way more topend power. Maybe a few rpm laggier but not much if at all.

As for going with a 6466. That is a big jump from the 50 trim. You will see around 600rpm extra lag. That's my guess. The 6266/6466 spool about the same and I know the 6262 spools about 400rpm quicker then the 6266. I daily my car on a twin scroll 6466 with over 650ft trq and over 800hp. It is ridiculous on the street. Like I said earlier I can't comment much on open scroll. I only know twin scroll setups.

Either way you should go with a 6262 if your looking for a little more fun with the car. Either swap it out and leave the rest of the setup alone or do like you said and still go 6262. Or look into the HTA3582 turbo i think it is called.

I don't think you will feel added lag and if so it won't be for long anyways.

 

Hmm this has got me thinking. I want my car to be really fun on the street... Its primarily street driven. What kind of power difference can be expected between the 6262 and 6266? Would 550whp be possible on the 6262 with pump gas??
