I'm getting ready to decide whether to do a 91 J-Spec 13BT blowthrough setup with my Weber 48DCOE, or.. get a J-Spec FD motor and go FI. The blowthrough seems to be a lot cheaper, after running numbers the FI would probably end up being around $7,000.. considering a full rebuild, porting, replacemeant to a single turbo, haltech ECU, censor.. etc. Just wondering, some people that did a swap in their FB with perhaps a 91 j-spec 13BT but kept it FI, how much did you spend with a full rebuild?

 

I Did BOTH.

I had a Haltech installed (and it was faulty), and went with a blow-thru Holley setup to get it running faster. The car did 380ish to the wheels at 17PSI. Was a lot cheaper than the Fuel Injection setup.

When I got my Haltech back from Australia, It was installed by Crispeed, and it runs like a factory car. No more hard starts, No more "Gas" smell running thru me and my clothes. Instant throttle response (no worries about flooding the carb), and much more power. No more bogging when taking right turns, etc.
At the same 17/18 PSI the car did almost 460 to the wheels with the Fuel Injection.

A Big part of the improvement was my Tuner though, he really knows how to tune a rotary.

 

I spent about 12-14k on my setup. If you run a stock motor you could probably do it for 7k(and build it right). A PFC is a good option, easy to tune and easy to operate.

A rotary is high enough maintenance already, that is why I did not consider a carb. Oh and did I mention that I get over 20mpg on road trips?

 

Yea thats what I hear.. Fuel Injection is the way to go for reliability, power, and saving gas. Seems like there are a lot of drawbacks to doing a blowthrough setup especially if I'm going to drive it daily.. Just sucks because of the huge difference in price. I can get the blowthrough done for like $3500.

 

Oh how lovely that sounds.. I'm running a stockport 13B with a Weber48DCOE slapped on and I guzzle gas like no other.

 

especially since you drive it like you stole it! LOL... the carb will work but programmable EFI will always win hands down.. its just way more money

 

FI I think is the way to go. My carb was great when going straight at full throttle.

 

By the way hows the new springs and shocks? Still waiting on pics of the wheels.

 

Very bouncy.. Gonna have to figure out what I'm going to do, what was your current suspension setup? Pics with wheels on coming soon

 

FYI I did it for less than $3,000 total invested. that's including a full jspec s5 engine and rebuild

 

Whats your secret?

 

The very bouncy feeling is now your suspension is tight. You went from original springs and shocks to cut racing beat springs and new tokico shocks. I am running ST springs and tokico adjustable, but changing to respeed coil overs and the rear shock coil over set they have. After I get this motor thing situated. No need for suspension when the car doesn't move under its own power.

I demand pics tonight. its still light out so get your fuggin camera and upload the pic.

 

Savvy shopper and does his own work. Meaning no labor cost which is where most of the cost is.

 

Did you leave the ST springs regular or cut the rear at all? I'll try.. I don't have my camera with me, grandparents have it.

 

Back in '97, I spend around $9000 for a N/A to TII conversion. Complete with Haltech E6A, Garrett T04E-60, and Spearco intercoolers....plus the necessary fuel mods. THis was before many parts were mass-produced for rotaries. With the advent of EBay and more parts availability, you should be able to get a blow-thru for around $5000, a few thou more for EFI

 

Jaime Enriquez your avatar cracks me up. Hope thats not really you.

 

Cut like one coil.

 

Hey Percent, how much have you spent so far? And, for the members, how far has your swap progressed?

 

HAHAHAHAHA...isn't it just such a pimpin' pic? Sorry...not me. The cross was just too much...had to have it.

 

Blow-through 45 DCOE and S5 turbo here. Well, soon anyway. By the time it's running, I expect to have less than $2000 total invested, including the rebuilt and streetported R5 13B. I'm doing it uber-ghetto style. Cutting corners. Used parts wherever I can get them. Doing as much of my own work as I can. Intercoolers are for pussies. I can't really recommend doing it the way I am, but hey, I'm a broke college student and I gotta have my boost.

 

HAHAHAHAHA

 

Thats's sounds very close to what I am haha. I just want that boost, but then again I have more of a mind set that if I'm gonna do it I might as well do it the best way possible the first time around to avoid problems in the future. I wouldn't mind so much if I had another car to drive in case anything happens but unfortunately I don't :P

 

I spent approximately $6K on T70 ballbearing (turbonetics), tial waste gate/bov, IC, custom fuel injection, yada yada yada and a newly built TII bridgeported motor with guru stud kit and Ianetti seals.

Just waiting to be installed as I cant decide on which car to install it to:

FC, 2 FB's, 73 RX-3 and 75 RX-3; what a headache

 

wacky put it in the blue rx-3

 

So many RX's.. so little time. Wheres pics of those FB's?
