Wayne's boosted 8 project

[Grant Monkhouse]

Soon as you have mede some engine mounts everything should be fairly straight forward.

The fd engine mounts from the rear and the rx8 mounts from the centre

If you are making this a full on racing car then I would honestly just get rid of most of the rx8 crap you can

Not sure about a full race car but full on track car for now
I hope this should sort the mounts
So yeah just keep the best bits from the 8 and bin the rest

Yeh I found that mount whilst go ogling, makes thing a lot easier. Wish I had an Fd engine lol

I’ve just had a look
Much more difficult for yours

Started emptying the boxes to see what fits . I was told the manifold would need some adapting but it’s a good start .
Had to remove the water filler by the thermostat but I’m not sure if the electric water pump may help there . I’ll
Dig that out next
Temporary bolted the turbo on
Bloody hell its heavy
Needed a socket extension bar to hold the engine to stop it from toppling . Might need a support bracket

Exhaust pipe is too close but not far off

Slow progress but plenty of time . Just hope I’ve put it together correctly , biggest turbo I’ve played with is Greddy which is the size of a large clenched fist.
I’ll take the upper inlet manifold off and offer in tomorrow and see how mush of the firewall needs adjustment
Reference what grant  said about the rx8 throttle body , seen this earlier 
Should do the job

Ha ha yep
I bought a load of stuff together and that was one of them
Just had a look online , judging by the numbers stamped it’s a
Borg Warner air works S400SX3-75/S475( T4 turbine )
Possibly a bit too big for what I need ,
Worth a try I guess

That a frickin big turbo! I mean, I reckon its far too big for you... Boost comes at 6000rpm, and hits you like sledgehammer

Adapter is a real easy route. I will confess the reason I devised a different inlet was that I did feel an adaptor didn't flow into the FD plenham properly and would rob power so I devised my own inlet . You will also find that either the engine will have to sit very low (too low), or you will have to modify the bulk head where it sweeps forward.

Thanks for sharing the info and photo Clive
I’m going to offer the engine in without it and see how much needs adjusting .
Looks quite a lot so may need plan B.
Where could I get a set of studs /
bolts as per following photo ?
Thanks

That is a big turbo, what porting are you running?

I'm running an s366, which is smaller than yours, good for 600hp, I have a full bridge port motor, but I have also got a small 0.88 rear housing as It is a single entry turbine housing.

If I used a dual entry turbine housing I would go up to the 0.96 rear housing.

The turbo should spool really quickly with the porting

However I am looking at getting another turbo, an S480 with a billet compressor wheel, 1.32 at turbine House on a T6 dual entry. Should be OK for drag racing, maybe not so much for track car due to slower response.

What size is the turbine housing? If you got a smaller one you would probably have clearence and it will spool faster

Yeah, cause mine is S300 series, even tho its Shwitzer, but basically same as Clive has. With 1,16AR it can do around 530 horses @ 1,6 boost and it spools around 3000-3500 rpm. And with big big D shape exhaust ports and BridgePort...

So, that size turbo wont spool, ever

The engine it’s on at the mo is supposed to be full bridge port , with ported inlet and exhaust ports . I bought it cheap without a compression test , just seen videos of it running .
It will eventually  be going a different engine which apparently has Cosmo end and centre plates , the inlet ports  are much bigger I’ll get some measurements and photos up over the next week .
That engine hasn’t been run since the rebuild , this is the one I had the turbo with .
As for turbo sizes etc I dont yet have a clue  , this is another learning curve for me so I’m open to any help and advise
Thanks
Wayne
