Tom went with that housing because he figured the larger inlet of the T3 housing would be better, but wanted to stick with the smaller T3 .48 A/R size for his low CR 1.6L. But I've heard the are pretty much identical as far as teh ratio is concerned. |
shlammed, where's your intake filter, in the tire well? pics of this now pleeeeze.

Damn, I thought .64 A/R was where it's at. Damn, I should have got the .8 A/R.

shlammage, 440s might be marginal for you.

:S
i was thinking that too. i NEED to convert my 92 over to sequential or im 100% going to run out of injector. what about fuel pumps... when do the stock ones tend to die? the FAQ just says PSI not horsepower they support i have a dyno tune day setup for the first of the month too. Sorry for de-railing this thread... i will start a build thread shortly. |
I don't think doing sequential gives you any more head room.
Fuel pump, guys use the stock one to 300 wheel plus on gas. I would think if you are above that, you've got serious money in your motor, a new pump is very cheap insurance considering the age of our stockers. |
There are 3 compressor trims 48, 52 (Sav's) and 56.
The 48 appears to be a nice size for a 15 psi street setup: http://www.turbobygarrett.com/turbob...47-1comp_e.jpg 52 trim: http://www.turbobygarrett.com/turbob...0-15comp_e.jpg Note that the 48 trim's max efficiency point is closer to the miata's peak torque in a 15 psi setup which would be around 250 hp / 25 lbs/min. The 52 trim would be better for a track setup because the max effciency point is closer to the powerband peak (~280-320 hp) The GT2860RS may be better at lower boost because its max efficiency point is closer to 10-12 psi and is probably better at spoolup at lower RPm because it's more efficient in the 5-10 psi range and lower flows: http://www.turbobygarrett.com/turbob...48-1comp_e.jpg There is a small trim GTxx60 - 55 trim which would be good for a lower power setup: http://www.turbobygarrett.com/turbob...60-7comp_e.jpg which is pretty close to the GT2560 http://www.turbobygarrett.com/turbob...-1&4comp_e.jpg |
