Marks RX7 - lets break a rotary.

[cossie1]

So things have escalated slightly. Just bought a Syvecs S8, going to get rid of the Link. Syvecs with new loom means I can get the Aussie tuner genius to sort proper knock and WMI strategies.

The new semi pp engine will be ready quicker than I thought, likely end of Oct, will share some pictures as it gets built. The plan is a large street port semi PP with some extra bells and whistles here and there.

I’m also going to change the exhaust manifold so I can run a G45 1350, manifold needs to be moved forward a tad for it to fit.

Sorry i'm loosing interest now, as it sounds like there won't be any more engine failures once this lot gets fitted

Just sat and read the whole thread - some serious dedication has gone into this, and credit where credit is due. You have stuck with it through all these exploding engines. I'm just upset i can't read on and see how you get with the new one! Look forward to the updates.

I’ve been busy.

I’ve purchased the lower inlet needed for my semi PP build from Billet Rotary in AUS along with a full DBW kit too from another AUS outfit.

Next up in a Winchester sump from USA - it’s a thing of beauty, I’ll post some pics when it arrives.

I’ve also gone ahead and ordered a new 36-1 trigger wheel kit from Fusion Engineering, also in US.

OE water pump and thermostat also purchased along with gaskets etc.

The Syvecs s8 should arrive this week after which I need to spend a chunk of change in new sensors. Knock, EGT, MAP etc. The tuner is very specific with the type of sensors to use.

To keep costs down somewhat I’ve found an American turbo company who can change my Holset 67/87 to a 77/87 keeping the 25cm turbine housing which is somewhere in the region of 1.25 to 1.35 A/R.

This means I can keep existing manifold, down pipe and wastegate set up. Turbo should be good for 800hp, I hope.

Will keep you updated with pictures etc as the engine gets built and the goods arrive.

I can see 12000 reasons there why you sold the 5.

Syvecs on it’s own makes my eyes water thinking about the price.

It wasn’t cheap but I got a good discount from the Aussie tuner Peter. I do however think all the sensors are going to be £1kish best guess.

I can offload some of the cost by selling my Link set up and loom.

Man maths. It helps justify anything.

Man maths. It helps justify anything.

The Man maths is easy on this.

Ecu + 1K worth of sensors = cheaper than another engine build after this one.

That’s exactly how I justify it to myself

 

[Mark Davis]

ECU has arrived from AUS. Very slick looking module.



Water pump arrived from Japan also with the OEM knock sensors to follow. I had a credit note from RHD Japan site which I’ve now obliterated.



I’ve been sourcing sensors today, I’ve been told to use KA sensors and seems there is a chunky lead time but think I have the ones I need.

More bits to follow. Used Scoff for the Syvecs connector and pins.

 

[Mark Davis]

Winter build bits are arriving from Aus, UK and Japan.

The car is getting its fuel system done this week.

Trigger wheel kit to move to a single OE sensor.

NTK style 02 sensor, EGT probes and OE knock sensors. My KA sensors arrived also from EPS Motorsport for MAP.

I’m expecting the DBW kit and lower inlet manifold from Aus this week also, pics to follow.

 

[Mark Davis]

New to me, low mile tank with Radium swirl pot set up. 3 x Walbro 450s, 1 lift pump and 2 feeds.

Flex fuel sensor fitted in line in the return under the car out of the way.

Lines and fittings up next.

 

[Mark Davis]

Another delivery from the land down under. This time Billet Rotary lower inlet for semi PP with fuel rails plus Dorito Design DBW kit.

 

[Big Steve - Raider]

Just love shiny new car parts…!

 

[Duncan Grier]

You get the best deliveries @Mark Davis

 

[Mark Davis]

Flex fuel sensor in the AN6 return. AN8 dual feed to primary and secondary rather than being ran in-line.

 

[Mark Davis]

Fuel filter in a way better position. Stock location is up above the rear diff.

 

[DaveL485]

Christ. And I thought I was good at spending money.

 

[Mark Davis]

Fuel system complete and porting started.

 

[Mark Davis]

Car is back - fuel system done.

Now time to remove engine for its new owner.

 

[Big Steve - Raider]

Now time to remove engine for its new owner.

The Car's new owner, or this Engine's new owner?! Can't handle you selling the car now!
