Yes, you are right. I linked the wrong thing. The Nissan cover also goes by the name of GT28 cover...at least that is what I have noticed.

 

That's because the GT2860R originally came in with that cover and the T25 turbine housing so that it could be a direct swap for skylines and such...it was uber popular.

I've played with hundreds of turbos and I honestly have yet to see a housing smaller than a T04B housing for the larger turbo's. The smaller T3 turbo's however get the tiny .42 A/R compressor housing which is super compact but it only goes up to a T3 Super 60 ( which is not too bad, it can push over 650whp on a twin setup and it's pretty cheap ).

 

huh, they obviously used a saw and welder the turbo in the pic which you find accpetable...

and special flanges dont mean anything either with a saw and welder.

 

What I was refering to, is that I don't want the customer to have to use a saw and welder.

Slight misunderstanding I think..

 

vr3 got twin 5557's to work in there. That is the setup i think would be ideal for my goals. I'm happy with what i have (once i get it back up and running) but the 5557 twins would be sick.

ahh ok. well obviously saws and welders shouldnt be left to the customer. HAHA

You could get the same power curve using a standard easy to install greddy 20g kit as well. that 6765 is a better choice in terms of install and powerband, once you get running again

 

but i think point of a BP twin turbo kit is to have a fairly easy install without having to pull the motor, which seems to be general consensus on how to properly install a greddy kit. Ultimatley getting you a fatter powerband than his single kit without the install headaches of the APS, Greddy, etc...twin kits.

 

Jeff, I think you will be very happy with the 6765 once tuned on more than 13psi of boost.

Also, those headers are custom, and I am trying to stay away from that. The idea is to have a TT kit that anybody can install themselves without having to remove the motor, relocate a bunch of stuff..ect. Bolt on is the key, just like the ST kit you have on your car now.

 

How much power would this turbo kit be aimed at?

 

Hard to say without actual testing. The GT2871R is claimed to make up to 400hp on a 2.2L, so your guess is as good as my.

 

I ask because if you wish to make an economical kit you could go with twin T3 60 trims Stage 1 with a .48 or .63 turbine housing and it should not only spool pretty good but power output could go as high as 600whp. Each turbo is about $600 too.

 

Yeah, not sure about the T3 fitment, it is much larger than the T25

 

at that point, you have to decide what's more important. a 1 time install, or slower spool that happens everytime.

BP has a nice niche market because his kit doesnt extend the uppipe any further than options already on the market. But the TT kits hang off the exhaust ports essentially. Theres no denying that spool will be effected, and to the extent it would be hard to say.

Pulling the motor is very easy, so i would not let that drive your decision. Plus if you were looking for a better powerband than is already offered in his single kits, you have to pull the motor anyhow to get it built...

 

To be honest, I don't think spool will suffer all that much at all. I don't see why it would. The distance from heads to turbo is minimal. I would only be adding about 4-6" of pipe from the existing header flanges. Now, if you are to get some tubilar manifolds, I am sure that it would go a long way as well.

As far as pulling the motor goes, it is not only during the install. What if you have to service a turbo. A friend of my had the GTM built motor with APS TT kit on, and one of the turbos blew. He took the car to a shop, replaced both turbos and the bill was $12,000 for parts and labor. Not to mention down time. Just something to consider I guess.

I know that I would hate having to pull the motor to service a turbo, and I am sure most feel the same way, easy or not.

 

sorry youre right, the B cover is the smaller one, its been almost 4 years since i sold my POS APS ST kit, i think it had that cover. i actually still have it sitting around if you need it to try out. you can have it.

 

You have the turbo or compressor cover? I think the turbo is a T3?

 

T3 5bolt .48 are pretty small. Not as small as a T25 .64 but pretty close to a T25 .86. I don't see it really being an issue.

I had a T3 50trim stage1 .48 in my garage about 2 months ago and it was pretty tiny.

 

Hmmm interesting...I should take turbo donation for fitment tryouts..

 

I'll tell you what....you can find T3 50trims on ebay ( early saab's and volvo's used them ) for dirt cheap. I've bought them for as little as $50 shipped and they fit in a Priority mail flat rate box.

 

BP, if this is the limit of a twin I would stay away from it. Your single kit is already capable of significantly more than this with the 6765.

Can you fit turbos with a higher horsepower limit than this with the design you have in mind?
