Hey everyone!

Just stoppin in to make my first thread (heck, even first post) ever in the 3rd gen section!

Ive been around the forum quite some time now, but usually stuck to the 1st gen section. Ive owned 5 first gens so far. I think I have some sort of mythical bond with them, haha... No matter what I do I cant keep away from them...

Always loved FDs, and recently the idea of turbo power started to be a major appealing factor to me. My favorite FB handles like its on rails with the suspension all done up but the power left something lacking.

I never liked the look of the FC, so I thought maybe it was time to get into the FD..
After looking around for a while and not finding anything reasonable, I stumbled upon a wrecked '92 JDM FD, running for an excelent price.

This made me immediately rethink things, deciding to stick with the FB for now..just swap over quite possibly the best 2 rotor production engine to ever be made, the 13B-REW !!!

1900 dollars later the FD was home, sitting beside the unsuspecting FB:




Now Ive done quite a bit of reading, and I think I have a prety good grasp of this marvel of an engine. There are however, a few mysterys that erk me.

Mod-wise the car has an aftermarket intake, and full 5zigen 3" exhaust, and an unidentified cat.




It also has a LHD downpipe ghetto clearanced to fit the RHD chassis:


Before I even think about the swap I plan to sort out all the issues with the motor still in the shell

I have read about boost issues with large exhaust... Would this setup be acceptable in a basically stock car? Looks like between that downpipe and cat, there should be some backpressure....

I feel as if the history of this car could be anything. I found this:


However the interior of the car doesnt have a single aftermarket box/gauge/nothing. no turbo timer boost controller or even boost gauge.

There are lots of plugs in the dash that look to have connected to such devices, but no electronics.

I plan to get a boost gauge to start diagnosing issues, but until then what else should I look for???
Im sure you guys will point out things I may have overlooked!

Thanks in advance! I Feel like Im already at home here!

 

sounds just like my story, owned 4 gsl-se's, didn,t like fc's, last year i imported a rhd fd. i think my problem with rx7's is a lack of calcium lol. so as for your boost box, u have to remember before they leave japan, anything inside that looks like it is something will sometimes get pulled out. so now they have 1 useless piece & u have the other. good luck with the fd.

 

I recommend you install a boost gauge and some sort of boost controller. (Manual boost controllers are perfectly acceptable). The high flow cat and downpipe will probably cause elevated boost and the controller will allow you to dial it back down.

Where does that line running from the Greddy boost control valve run? Whether it's connected correctly or not you'll need the electronics to make it useful.

Ok, so the car was losing a bit of coolant when I bought it..

The other day I bought myself a coolant pressure test kit (didnt want to risk it running the motor to find the leak) and it turns out the rad has a small crack in it.

I wont be running the motor until I have the cooling system back up 100%.

Meanwhile Im just trying to sort out all of the obvious bugs.
I have been looking over the vacuum system, and have been attempting to complete the simplified sequential system setup seen below:



The biggest cause for concern was the boost controller, so I began trying to re-plumb the visible lines.



Im having a bit of trouble with the vac. diagram, is this how the wastegate and precontrol are supposed to be hooked up? I can make sense of most of the diagram but this area of the picture is very small and vague..

Its definately missing the restrictors, so there will be more questions to come on that..

Basically just wanna make sure I am on the right track here!

 

Yes, that's correct. It wouldn't matter if you crossed the lines anyway.

You may have the version of the turbos with restrictors built into the nipples at the top end of those hoses. Pull the hoses off at the compressor end and if the opening isn't constricted then you need to add pills when using the stock boost control. If you have the built-in restrictors you'll need to drill them out to install any aftermarket boost controller.
