Hey everyone! I typically just roam around on the forum without actually getting involved so I thought I’d do my part and post up my 7. I have owned a couple of sports cars in the past; NB MX5, S2000, and C5 Corvette.

The FD has been my dream car for many years now, and I was keen on buying one late 2014 but then I realized I wasn’t financially ready to have one. Over the years I browsed the rx7club forums learning as much as the car as I could without actually owning one. I moved to England from the states (Virginia) in July 2018 and I knew I was going to buy a FD here while living here and bring it back to the states after a few years. I first saw a white one in Southampton from an importer, but it sold while I was sorting out money (never left a deposit). I then found a VERY dodgy one near Leeds which I decided to walk away from (they couldn't even get it started).

The dodgy one:

That very same day, I found my FD on eBay. I bought her from a guy in Burton in August 2018 bone stock aside from a cheap anti-theft system and turbo timer. Within a month or 2 I installed some new indicator lights, R1 lip, PFC, boost gauge, and koyo rad (I'm sure I'm missing some things). Here are a couple pics of the car as I bought it.

I enjoyed the car for a few months and I made the mistake of boosting her while cold (should have installed the boost gauge sooner). Not long after, my car was showing blown coolant seal symptoms. I was in denial, I only had the car for a couple months and I already needed to rebuild the engine?!
During this time, I took my car to super 7 autos to have a fiberglass 99spec bumper rep installed and painted (I’ve always loved the look of the 99 spec FD). Not long after, I was referred to Era at Oldones by @Sturneyrx7 and after a short phone call, I was sold! I wanted to keep the stock twins in the meantime so I could experience them before I went single. I opted for a standard rebuild using Mazda OEM parts and a small street port appropriate for the twins.

We were lucky enough to finish the build and get it installed back in the car just 2 days before JDM Combe last year, where I met a few of the forum members. First Drive was the 2 hour road trip from Banbury to Castle Combe, so it was a bit nerve wrecking but it made it there with 0 problems!

Engine install the night before:

During the break in period, I installed a cheap SMIC with a duct (first time doing this with fiberglass), 3” midpipe, and 3” downpipe. After a month and 1500 break in miles, the car was ready to be mapped by Marco. The car made 339bhp on stock fuel and ignition, but the injectors were hitting 90% duty cycle so the session was ended with the recommendation of upgrading my fuel system and adding a twin power. Marco also found that the first turbo was on its way out so going single was in my best interest in the near future.

The car was fast, definitely a lot faster than stock with water seal issues! I enjoyed the car for a few weeks before it started showing ignition issues. It would misfire under WOT, possibly due to the injectors maxing our and lack of a twin power (and possible harness issues, etc.). After a highway run one day, my car started idling weird and before you know it, the engine would not start AT ALL. I think I spent 2 hours trying to get it started and ended up flooding the engine. Since I didn’t have a compression tester, I took the spark plugs out of the front housing and cranked the engine with a 19mm socket and ratchet and heard no puffs. Yep, apex seal gone. I already had a used single turbo setup waiting In the garage so I just said “screw it” and pulled the engine and ripped off anything that had to do with the stock twins. I took the time to feel inside the front housing with my finger through the exhaust port and discovered a nice deep gouge near the port...yep, blown apex seal.

Engine out again...

I decided to do everything I could to the car while I waited to get the engine to Era for the second time this year. Fuel pump upgrade and rewire, single turbo harness conversion and re-wrap, painting the engine bay, cleaning parts, etc.

Cleaning and regreasing parts like this:

I didn't want to go through getting my car towed and completely disassembled to have the engine bay painted professionally. Maybe one day ill do a full top to bottom restoration of the car, but for now I am happy with a degrease and rattle can paint job. I got a bit lazy and just decided to leave the fenders (wings) on and tape the rest off, and overspray was minimal enough for me to live with it. I think it cost me around 40 quid for the touch up spray paint and primer and I'm happy with the results...much prettier than just leaving the bay as-is.

Fuel pump. I decided to de-pin and re-pin the original bulkhead connector, then I will be doing a full rewire with a relay directly to the battery. I went with a Walbro 450lph pump

Era will be getting my engine (for a second time) along with a used housing this Thursday and hopefully I’ll have her running before February! We will be opening up the ports for the single and sending the housings and plates to get resurfaced by Colum.

Nice mate, I feel your pain.

I bought my FD in July and chipped apex seal within my first week of ownership.

I share your tenacity as I think many would give up and move on.
Thanks man! The only thing keeping me going is the fact that it’s my dream car, although I’d love to get a break from the repairs🤣

What was the cause for the engine going? Did Era rebuild Iraq before mate?

engine bay clean up looked good mate!

nice car 👍🏻

So when Era tore down the engine in april, he told me that it was all original (around 70k mi) and the only reason why I took it to him was because it was burning coolant. As for the apex seal, I was getting ignition break up under WOT and also my injectors would regularly hit 90-95% duty cycle. Yeah, I know I was playing with fire and I’m paying for it now.😅To fix everything I’m getting the engine rebuilt, upgraded my injectors with rail and Fuelab mini FPR, walbro 450 pump with rewire, and twin power

A shame it has to be rebuilt a second time - Have you thought about getting Goopy Apex seals in 2mm standard form to safeguard your engine from being damaged again? These seals will only bend and not shatter if something goes wrong, protecting the rest of the engine whilst only the seal needs replacing worse case scenario. Mazda seals will shatter if something goes wrong again.

I actually do plan on going with goopy seals this go around, I’m just waiting for Era to tear the engine down and tell me what size seals I should get. He said that OEM seals are good but when they break, they take out the housing with it usually😂

Update: Threw the keg and extra housing in the back of my daily on Thursday and hauled it to REWorx for porting and rebuild. I’ll know exactly what I need for the rebuild once Era tears it down and inspects everything. My Fujitsubo Legalis R came in the mail today from Japan! It’s definitely used but it was only $160 shipped to my door so I can’t complain. I like the tone of them and it’ll quiet down my system a hair. If anyone needs things from Japan/USA, shoot me a DM and I can get you things MUCH cheaper👍

Update: Got the status of my engine tear down. Housing is trashed but the rotor and side plates are okay. I got lucky! If all else looks good after the clean up, I may get away with just replacing the housing (already purchased), water seals, and only 1 apex seal! Any thoughts on this? Much cheaper replacing the 1 apex seal (all are Mazda oem seals) than buying aftermarket goopy seals, but I do like the idea of not having to sacrifice a housing after detonation...

Personally i dont like to mix new and used parts and would probably fit goopy seals anyway. It's a time vs cost and the added value of having a more reliable product.
For me, time is the killer, so whilst its out i would do everything possible and make it as reliable as possible.
To give you an idea, i started my suspension bushes months ago and i've only done 1 corner, and thats been sitting on a bench for 2 months.

I was thinking the same, I’d rather not cut any corners this go around. I lucked out with only having to replacing a few parts since the rest have around 2k miles on them. I’ll give the goopy seals a go👍

Update:
Since there was finally a break in the weather, I decided to tackle the relay box relocation I have been putting off. Made up a steel bracket to mount the box as well. Not sure why I chose the drivers side, I just felt like it looked more at home over there. Glad I had plenty of practice with crimping and shrink wrap! Total of 14 wires needed to be extended...8 20awg, 4 16awg, and 2 14awg wires (need to come back and finish one last horn wire). Took hours to complete but I’m happy with the result. I’ll wrap it with silicone tape once I get the engine back, I want to make sure the car runs before I wrap it in case I need to make some repairs. I also plan on cleaning up the brackets and powder coating them once my supplies arrive in the mail
