Hello,
I love rotarys and everything about them, but without boost, FDs struggle a little. I think that boost comes on a little late......both turbos spool up at about 4500rpm....other cars spool up at 1800rpm. When boost does come in, they absoulety fly...but i do think that it takes its time.

i think the previous owner converted it to a non-sequential. check under the uim and see if their is a big jumble of hoses and brass or copper tubes. also a vacum chamber

Yeah...stock seq. have very little lag sooo you must be running non-seq if your complaining about lag.

akiratdk

yes non-sequentials do that.... I have that setup and it really annoying for a daily driver.... I want a single turbo!!!~~~~ for me going back to sequential is too much work!!~~~

rexhvn

Lol. I would love to go to single but i love the quick response. What rpm do the seq turbos kick in? I'm not complianing lol hehe:P it's just when driving with the foot to the floor, it takes a little time for it to start really going before boost kicks in.

running REAL non-sequential is much much better. full boost by about 3500.

I've read that non seq are better to run, less hassle and better for daily driven 7's. Just a question for example, with those with and without non seq, how do you do when racing people, does the time of boost effect the race?

Where did you read that BS?

Sequential turbo system is good throttle response from 2500 rpm and up. Your car is setup poorly for decent response. Almost any single turbo setup would spool and respond much faster than your current situation....

The only cars I know with turbos that spool under 2000 rpm are VW/Audi 4-banger turbos....who cares. They also run out of breath at 5500rpm too.

I suggest you learn more about FDs and fix yours before criticizing their turbo response!

You'll read a lot from people who have a minor problem with the sequential system and immediately run from it.

They'll either convert to non-sequential or install a single turbo, and sing to the heavens about how wonderful it was - but very few of them ever experienced a good sequential system or made any effort to fix it. So what you read is, of course, biased material.

^ THAT is what I was going to post! Dammit Dave....
Seriously though....to the original poster....you just have something not working right. Get the Factory Service Manual (there is a PDF version available right on the Forum...see the sticky note) and read up on the turbo control and pre-control systems. Also make sure you don't have a broken Y-pipe-to-intercooler coupler leaking boost.
These cars in sequential spool FAST! The design was highly acclaimed at its debut. It is very effective.

IMO, this is right on! My sequential system's operation is fabulous. Quick response anywhere above 1800 RPM, full 11 psi by 3000 RPM, quick transition to secondary at 4500, 11/9/10 boost pattern. My mods are in my signature.

I bet its somethin to do with your turbo control actuator, charge control actuator, or the solenoids for both...You probably just have no primary boost, then both turbos come online at the same time. I had that problem once.

Well eirther way, it isn't the rotary's fault.... rotarys build an awful lot of exhaust energy being basically a 2-stroke... producing the enefy to spool turbos really isn't it's problem.
