Cost mainly....It got it for a decent price. The r154 is proven behind 20Bs & the conversion is not too hard.

 

Cheers, struggling to find a r154 at a good price that hasnt been thrashed - almost cheaper to go the mangum and be done with it.

 

Cheers

Started making progress on the sump, she's going to be sturdy!







Going to extend the factory oil pick up further to the rear, then I can look at putting the car back together

 

Made some great progress in the last week. The new sump is finished and is a sturdy bit of kit


All cleaned up




A different view, O-ringed too. The cutouts make room for the oil pick up, which extends to the most rear and lowest point of the sump.




All buttoned up




Picked up a quick shifter for the R154 too




Good Times Not to far off re-installing!

 

Have made some great progress of the last few weeks and have been enjoying putting it all back together

The motor and gearbox is back in and the shifter lined up perfect.



I'm looking forward to trying out the quickshifter

Had the exhaust manifold, housing and dump all ceramic coated, come up a treat




It should help with engine bay temps and improve the efficiency of the hot side.



Worked some heat shielding around the LIM, there was always a great deal of heat soak. This will help combat the issue, and will work well with the ceramic coated exhaust pieces.

Nearly back on the street, a few things to go. Looking forward to the tune.

Looking at some bigger secondaries too, maybe the Siemens 2300cc. Has anyone played around with these?

 

Over the last month, I've been chipping away at getting the car put back together.

First up the radiator shroud is finished along with a -20 AN fitting welded the the top inlet of the radiator as well as the thermostat cover.
Also added a twin belt pully and modded up an early FC alternator bracket so it's the same as the later top bolt tension set up.



With all the upgrades and what I think are improvments, the car is now driving

A few shots of the completed set up.



I plumbed in one of turbosmarts nice looking BOV this time too.




Gave her a wash and took her for a quick spin




Just finished wiring up the eboost2, next stop will be the dyno...

 

Must be a great feeling to be able to drive it around

 

That rubber line going over your DP and through the heat shielding will not last long before it turns rock hard and crispy, based on personal experience. Consider covering it with heat shielding or replacing it with some type of high temp braided line.

 

The best

 

If you look closely, you see that the booster line is covered already........

 

Doing the final few things before it's time to hit the Dyno.

Just swapped out my secondaries for some 1700cc units. i'm hoping the staging of the secondary injectors will be smooth, time will tell.

Working towards the same event I entered last year, the Snowy Mountains 1000. Top speed/ time run over 1000m.

I hoping the improvements and gearbox swap will yield a better result this year. I've also been working on an aero front bar, which I hope will help front end stability.

Anyway, I just clicked over 20 years with the RX7, she's seen a 12A, 13BT and finally the 20BT thats resides in her today!



Treated her to some new wheel, older style 16" Simmons F90's.

 

Cool thread mate. the comment about all 3 engines is pretty sweet. not to many can say they got past the 13bt! I hope you get the results from the event that you deserve

 

Cheers Bro!

 

So its Dyno time!




Got the War machine up on the rollers and had Bill Nabhan of MazSport Australia do a nice safe tune for me.

Ended up with a conservative but enjoyable 460hp, which will be nice on the street and hopefully yield me a decent time in the upcoming 1000 meter top speed run I have entered.


*The video quality is a bit poor, filmed on a phone.

I've modded up a Group C front end by fiber glassing the indicators and one brake duct.

I've also blocked off the frontal intake area ( there are five 1 1/2" holes to allow some air flow which hoping will help combat the frontal lift of the car during the run.

As it's only 1000m, I dont think the car will get too hot... but time will tell.

 

Your engine will cook with no air for 1k and the spoiler will create more lift and slow cars top speed

 

Looks great!

 

Well had a great weekend away down at the annual Snowy Mountain's 1000.

Car ran really well. Didn't over heat with the front end mods.

I had three runs, all with similar speeds and times.

Run #1 255.9 km/h @ 22.8 Sec
Run #2 253.3 km/h @ 23.6 Sec
Run #3 255.0 km/h @ 23.3 Sec

The car is not going to go any faster without more power, so I've found the limit there.

While the time to cover the 1000 meters varied as I struggled to get the car off the line, played with the boost settings a bit but really need to get some bigger rubber...

Overall the car was planted in the front, and no lift but squirmy in the rear...a small spoiler will solve this. Next time.

Here are a few pics of the day.


The drive to the Snowy Mountains.



Hanging in the pits.



Front end taped up and ready to run.



1000 meters of full throttle.

 

that last pic is so sweet. consistent passes. hope to see you make some improvements.

 

Hows the box going... I think I'll be having to go the R154 path as well.

 

Hey bud, box is awesome. Short throw shifter does wonders too. If you cant find a decent 2nd hand box, look into a new one from toyota..

 

I just been looking into the r154 as pretty reasonable brand new here in nz. do you have any of the Martin crawler parts in it? eg bearing retainer or thrust washer or billet shifter forks?

 

I've read up on the Martin Crawler parts, some good options ..Mine is factory, so I'm hoping she holds up.
The Supra boys have much heavier cars to move, so I'm hoping the lightness of the Rx7 can help....



One of the full throttle passes

 

Another pic of the 1000meter run, this time from the start.

 

May I suggest a TKO600 if your budget stretches that far.

I bought mine brand new and had Mal Wood in Qld rebuild it with their performance pack.

Good for 600ft/lb of torque, and was $4300AUD delivered to me.

Obviously clutch, bellhousing etc is on top of that.

 

SO a few changes coming up for the War Machine...

TURBO TIME

Borg Warner S300sxe-69mm (9180)



I had a few turbo's in mind before I decided on the S300... I was thinking the BW efr 9180 at first, it was actually Howard Coleman convinced me on these new units.

Once i read up and looked over the map, my mind was made. These units flow a ton of air and at such an affordable price compared to the other turbo's I was considering



Sizing the dump up...





Looks right at home!




Not the most exciting Pic, but I picked up on of Race Only's (rx72c) mechanical WI kits too!
