What turbo sizes are you running?
just have a few questions on what sizes and the specs of the turboes every one is using
I know most everyone is using a T3/T4 or a T04e... but what are the specs on them?
The PFI T04e uses a .81 A/R which seems to me a bit high... what are the A/Rs of the other kits and turbos everyone is using?
anyone have any complaints about a Garrett T04e 0.70 A/R compressor housing 0.60 A/R exhaust housing??
I would really appreciate ideas and opinions...

I have a T4/TO4E. AR81. Yes a 60 or a 70 AR would be better. 81 is good for top end runs. I would not get a .81 for a non ballbearing turbo. Id get a .58, .6?, or even a .71.
I have stock manifold on my car. Put out 353HP 318lbs of torque, so I am confused as where is the inefficiency? Ramius put out 400HP/360lbs of tq with a spike to 11PSI. He has stock manifolds.

One of the turbos I peeked at was a Garrett T3/T04e super 60 with a 0.63 A/R turbine (exhaust) housing. 0.50 A/R compressor housing- pretty decent size... maybe a bit small
another T3/T04e combo is an0.70 A/R compressor housing and i choose exhaust housings from 0.48 A/R, 0.63 A/R, and 0.48 A/R Dodge/Chrysler T3 turbine housings. it has a 57 Trim Garrett compressor wheel
they're ok, but yea Daniel my car just goes down the freeway really fast haha I have my 240sx for the twisties
I cant find too many sites that have a good selection of turbos at good prices, especially T04 turbos that dont have huge A/Rs for domestics

Woah...don't forget the I4s have that turbo practically sitting on the exhaust ports compared to the Max's 10-mile reverse y-pipe, so that adds lag. Not to mention I4s can easily run divided turbine housings to offset one-to-two size larger A/Rs.
As far as I remember, a PFI T3/T4 was hitting ~6psi by 2800rpm even with that super long reverse y.

As Jay has mentioned, we are both running the same turbos on nearly the same turbo kit.
I have a Turbonetics T4/TO4E Ball Bearing Turbo. It has a .63 on the compressor and a .81 on the turbine. I purposely chose the larger exhaust side so that I could atleast start moving before I hit full boost and lost traction. But I still loose traction regardless if I am in 1st, 2nd, or even 3rd. I start boosting by 2400ish and I have max boost regardless of psi setting at around 3500ish.
When I dynoed untuned, I had it dialed in at 10.3 psi and I had an 11 psi spike that was held constant throughout the run. At that 11 psi line, I have a little over 400whp, and around 368 TQ. (Torque levels are low because of no moving air on the dyno to cool down the IC).
I would rather have the top-end power with a larger turbine, rather than having the boost in the lower end and spinning through tires trying to get moving......

Where do yall get off trying to say the maxima header is inefficient? "I have seen 1.6 liter B series fully spool a t3/t4 at 3000 rpm. " First off people seem to forget the word FULL SPOOL means nothing on a turbo, what psi we talking about? Cause technically full spool on a t3/t4 is about 2bar.
Explain to me how I start spooling the turbo at 1psi at 1400rpm? Ask bags533 if you dont believe me. I can be at almost 15psi by 3200rpm, how is that inefficient?

It would probally spool even quicker with a smaller manifold, like a crossover pipe. Maximas are doing great! I am just saying other engines like the B18 make almost the same amount of hp as a maxima at a certain PSI. Give a take a PSI. But the Maxima makes alot more torque because Hondas don't really make any torque till the VTEC kicks in. They alredy have 500 - 1000 less lbs. than us, and I am just trying to get the upper hand on them. We have at least 20-30 fully built civics here in Houston, and probally twice that semi-built. Each running about 16 -30 lbs. of boost.

My experiance with a .81 non BB T4/60-1 was great until I tried to race a WS6.
With the .81 I would get 1psi at 3k & 10psi by 4.5krpm. Car felt fast! But what I founf out was that the spool up time is more critical than the rpm where you get boost. I was next to this WS6 and we both hit it at the same time, he jumped me good! When I spooled up I could hang but he was 2 cars out already, awefull! I have decided to go with a .58 turbine.

What mods did the WS6 have matt?
Was it a T-top? Were they removed?
I ran a friends WS6 and I pulled on him slightly from 2nd gear @45 mph but he would even it back up in 4th

I met a guy yesterday with the next size down t3/t4 than me. He has 1 psi @ 3800 rpm and full spool of 22 psi @ 4800 rpm in 3rd gear, with a 8000 rpm redline.
He makes ~420 whp, but I have 1 psi @ 2600 rpm and full spool 7 psi @ 3400.
I make more WHP than him until 4300 rpm

It was red with a license plate that read somthing like WS6GIRL, a dude was driving with a girl in the passanger seat. It was some time back, I cant remember if it had T's or not.

ok, I was just curious....
I'll talk to you more about it since your here
