What should i do to my FD
I currently took my motor apart out of a 93 touring fd and i am trying to figure out what to do with it. I want to make about 400hp. During the break down we noticed that i needed new stationary gears if any one has them up for sell i'll buy them, the only thing else that looked bad was my side seals were stuck in the rotor, ....the question is should i let this guy that owns a rx7,and i believe he is a current user of this site, port and rebuild my motor for 750? he has probably only ported and built 10 motors or less i would guess?

Who is the guy? If he has successfully ported and built and 10 motors, then #11 will most likely be fine as well. You can either build or you can't. Porting is more of a black art honed over time, however.
Worst case, Gotham Racing isnt very far from you, down in Fort Worth TX. Steve is one of the best porters and builders around, so you have options.

I agree with goodfella.
If he has built the engines before, he can build one again. They really arent hard to do. Print out the FSM, make sure you have the right tools, TAKE YOUR TIME and be very meticulous with your cleaning and do it yourself is my advice.

I don't necessarily agree ulost2my7.
Have you ever done one of those 3d puzzles before? well IMO an RX7 engine is NO different except you have to keep it clean., except it takes some patience and cunning to get it out, and time to do the rebuild of the block itself.
Pay attention to everything, and you cant put a foot wrong really. But if your buddy wants to do it, let him.
Is that price with or without new housings? does it need them/

Its not hard to do a rotary engine, you just need to take your time.

There are lots of things that can go in backwards, upside down etc and the manual is definitely not that clear in many cases. If I didnt have an accomplished engine builder showing me step by step what to do I would not have been very confident in my first motor. There are also many small 'tricks' to make motor that much more reliable.
If it was easy, no one would take their FD to a shop to get a ported and built motor, they would all do it themselves.

like others said...if he did 10 sucessfully then 11th would be just good.
Personally, I am on my 22nd Ford 302 shortblock and 4th on 351W shortblock...my first rebuild was a 306 cid motor which today still running strong with 14 psi Vortech charger.
Engine rebuilding is fun...nice quiet time alone away from everything else.

I agree 100 percent, and thats why i said, "just take your time".
If a 16 year old kid from the 2nd gen forum can build an engine day after day, im assuming its just as easy, if not easier, than it looks on paper.
And i was even told its much easier to build one since it has less parts than a piston engine, thats why i said its not hard cause i did an SR engine before, im sure with some help, the right tools, i can do a rotary engine myself.

Building the motor is one thing - getting all the crap that bolts onto the motor installed properly for a properly running leak-free engine is another. I hope you thoroughly documented the breakdown of the motor . That's what really takes skill, IMHO.

i agree 100% with Daleclark. Removing the motor is a pain in the ***.
I also agree with goodfella, it is easy to minimize it. But not everyone builds their own motors because a) they are scared b)they have no space c) they dont have the tools d) they dont have the time
If you have it as a second car, a reasonable sized garage and and reasonable compliment of tools, you can do it yourself no problems. It might take you four months, but you can do it.

I agree with GoodFellaFD3S. You cant go wrong with Gotham. You can do all your homework on the work that Gotham has done and you will find no problems. Steve is the best at what he does. Building and tuning. I did my homework and thats why Gotham built my enigne and will finish building my car. So good luck on the car.

The building i would like to try and do it myself so i will learn more about maintaining my car, i was kinda looking for a repair manual if any one had one for sell or could send me somewhere to get it., but the porting i have no idea how to do it? Do you have it hand ported or have a machine do it?

I ported my motor at Gotham (I am part owner) so had all the tools and bits at my disposal and had steve's input (and ported housings to use as templates) throughout the process, and it took me around 30 hrs from start to finish over the course of about 5-6 weeks.

I thought I would throw up a couple of pics since I tore down his motor, and told him I would rebuild it if he wanted. Thhese are a couple of ports from another FD I am doing.
Finished primaries and almost finished exhaust.

Rebuilding a motor is not easy nor is it impossible. I was really daunted at the task of rebuilding my first motor but when I got done I was like wow that was a lot easier than I thought it would be. I had a harder time getting it back in the car and getting everything hooked up right. The main problem people have with bad rebuilt engines is that the engine builder used sub par parts in the rebuild. Someone who has rebuild a few motors doesnt know what to check to see if your parts are in spec. If you have all new parts now that is something different. The fact is most people are not mechanically inclined enough to be pulling their own motor and rebuilding it themselves. I have done a lot of my own work and I would not have been able to R&R and rebuild my motor without guidance from an excellent mechanic. Rebuilding a rotary motor was easier for me then the mazda 1.8 engine I recently rebuilt.
