i just bought a 89 fc TII not too long ago. now im looking into building it . not exactly sure what i should do . its quick now but not fast enough for me . im not looking to drift, or drag .. more of a weekend worrior type . im looking to do a STRONG and RELIABLE 420-470 hp. i was thinking of maybe 3mm seals, studded motor, rull race stainless manifold on a T70 w/ AR .98 hotide on a micro tech LT10s ecu ar roughly 18 psi of boost. what do you guys think ?, if u think another build is suitable , please let me know !! im still a slight noobie to rotory

 

Sounds like all you need is some weight reduction.

 

That's a very specific horsepower number.

The T70 will do it, but is a lag monster. Very old technology. There are better choices such as the GT35R. Will typically make just under 450HP at around 18 PSI. GT40R will get you at the 450HP power level at 15-16 PSI depending on other factors.

The LT-10s is a stone aged ECU. There are far better choices, such as the newer Haltechs.

3MM seals aren't really much stronger than 2MM. The only reason to use them is if your rotors are too worn to accept 2MM.

 

thanks aaron .
ive heard of few people in chicago using the haltech ecu but the problem by me is finding a shop to tune it . most of the people running on the street by me that are using that ecu are alot of puertorican people people i keep in contact with but they have a "guy" from PR that comes to tune it . most people by me seem to use the micro tech bc its more "user friendly " for tuning?
ive heard on another thread about someone using 4g storm link ? idk what that is but from what i read its like micro tech only cheaper and doesent use data logging?

 

Id go with the gt35/40 turbo for those numbers. very reliable turbo with good reputation.

 

Welcome & congratulations! If you go with a Haltech talk to Ryan from Shook Motorsports out in Rockford. Ryan knows rotaries & Haltech's very well & is someone you can trust to do a good job. His contact info is in his website below.

thanks for the contact info fc3c69 ! and yea i was thinking of going with a ballbearing but they can get costly lol . and roughtly... lets say 35, 37, or 40r turbo , how many lbs cana studded motor hold. ( yes i kno the larger the turbo , the more pressure= more hp and that 20 lbs on a 30 r is not the same as a 40r ) but i mean roughly?

 

Are you certain your going to stay rotary?

 

The Microtech was a state of the art ECU...10 years ago. It is so limited compared to every other common ECU used that it shouldn't even be considered. It doesn't support closed loop, saving of maps to disk, 3D timing tables, real data logging, and a host of other things that have been standard functions of ECUs for a lot of years.

Plus, the laptop software sucks. I mean, it is absolutely horrid. Obscure key shortcuts, an interface that mimics the hand controller, and **** poor COM port support. I consider the software shortcomings to make the ECU far less user friendly than others.

I'm not sure why you'd ever want to rely on a "guy" coming all the way from PR to tune a crappy ECU, when there is a community of rotary people on this forum that can likely point you to many people with Haltech experience in your area. Plus, you'll find that if a person can tune a Microtech, they can likely tune any other ECU because the principles are the same.

Studding really isn't based upon boost pressure, but engine power. At 400HP it's not necessary to stud/pin the block. At higher HP levels, you get into territory where it is.

 

well thats one of the reasons why i joined this forum . I'm not rotary literate for the most part. I'm piston guy , and starting to switch over now that i own a rotary. thank you for your constructive criticism, that is what i posted this thread for . i want people to give their opinions and reasons backing their opinions so i don't find myself wasting large amounts of cash.

Rotank, yes i have thought about a swap maybe a 2jzgte , and kicked the idea of a ls swap too . but for the money it cost to swap , I'm still gone want to throw some upgrades to the swap so i think the cost of a swap might outweigh using the 13bT that is in it now . i still have a lot of time tho.....
