Project Motomachi Supra Build

Recommended Posts

So my supra is with littlenum, @performancehart and has had a full underbody restoration, I wanted some little engine work done also, but I couldn’t resist building the engine, going fully forged. It was also recommended as we got deep into the engine anyway. It’s a pretty impressive spec list which we’ve decided on.


This build will all be revealed in a progress build thread documenting all the steps from the moment I got the car, making a dream come true, and the moment James took the car in, and up until the current date.


Got a little bit more to do before I start a project thread, few more parts on way from at Tim @TBdevelopments.


Want it to be a nice thread with plenty of pictures and details etc, so that’s to come over the next month or so when I get plenty of picture ready of parts and James steps taken.


For now a few little teaser pics of a snail, Simba seems to like it! :)

Some more goodies arrived today, 4” funk motorsport turbo filter and carbon housing jacket

Well down-pipe is nearly finished.    unfortunately the 4” wouldn’t fit so had to go 3” until we cleared the manifold.    Bit annoyed about that but it’s the way it is, hopefully it won’

Yeap fingers crossed mate. Hopefully should all work as planned

So it’s March 2017 and these are the first photos I got of the supra, thought I should start from the beginning.


Alex the previous owner sent her on the trailer I booked, down to srd to have a mot test, and full check over.


Srd did the vehicle checks and all passed, then a pre mot check was done, it needed a few bits, so they wired in a fog light, done a full geo setup, replaced a spilt vac hose, secured rear battery, changed engine oil and filter as I requested, and fixed the non working horn wire.


It failed the mot, Rose track joints had play and abs light was on.


So srd checked this and the abs light wasn’t plugged in so plugged that in and put new rose track joints on and she passed.


Minor advisories were for jacking point damage, the usual bent jacking points, and a second advisory for a slightly binding brake calliper.





Quick few pics a friend took on my journey home from srd. On my way home I noticed it was holding back and backfiring at 4K revs was a bit confused by that.





Seems that after going through every possible scenario, including the Syvecs ecu, it was a faulty fuel pump so got a new walbro 450 in there and ran perfect.


Gave her a good well deserved clean up after that.

James checked them car over did a new mot on the car just after she arrived there and passed with flying colours.

So I started buying parts for the work James was undertaking, changed my mind on the parts/build a few time’s over the course of time James has had the supra but things had to be right and now we are set to build a nice supra!

James started stripping the engine ready for the build, manifold bolts stripped so had to get a new set.


Other than that James said the engine and internals were very good condition. Only being 50k miles you’d expect so anyway.


So James is now stripping it all ready for machining and forged internals etc in the next few weeks

The underneath of the supra prior to all the treatment was spot on, no corrosion at all, all cavity’s were checked etc, but it’s something I wanted done to protect into the future anyway, our uk weather and roads are shocking so it had to be done.


As your see the underneath was perfect before and even better after!


James removed all components, deep cleaned the underside, removed all surface dirt, grit/dust etc and any degraded under-seal.

She was then dried out for 48hours, and moisture tested.

Which is most important part to stop present moisture as any moisture left deems the future protection useless.


Some pics!
