Wtf how much ????

Why ?

It’s a bit of pipe

Oh no, that amount is the total for manifold  and the turbo and other bits.

The manifold on its own is 900 dollars

Again how much ?

Yeh I know.

Think my manifold cost me 200quid tops

What kind of exhaust ports you have?

Cause turbos that size, will probably need big peripheral d ports to start spooling earlier I have no idea how Renny side ports would get it to spool early...

Power is nothing without control. Weight is enemy of performance, handling and braking.

Yeah
Wondering if I can measure if they are ported but I guess most of the work will be done on the inside .
Wondering whether to pay some one to take the engine apart to see what’s what before I get it going .
Or would anything be damaged if that was done

You wouldn't damage anything having it pulled apart, slight chance you might need to put new water seals when putting it back together but everything else should be OK I'd say.

Take a picture of the exhaust ports with your flash on, might be able to see if they're larger.

Some people don't open the exhaust ports much, some people open them up a lot.

Do you k ow who did the porting on it?

It’s alleged to have a  race bridge port with ported inlet and exhaust ports . The buy was a bit of risk and reward . If it is as said was very cheap . If it does need work it would still sit under the price of a rebuilt engine .
Came from time attack race car .
Hence why I’d like to get it taken it apart to check .

No point taking apart for looksee  as may as well rebuild. If she turns over nice by hand with even compression resistance voila. Or connect to gearbox and starter comp test.

I did think about that
Was worried if I would damage anything without oil in the engine
Oh , and would I need a clutch as that’s not fitted yet

But of oil squirted in there and turned over by hand will guve some protection. Plus the engine should have built with assembly lube.

Turn the motor over by hand and if you hear 6 good psshhts it's alright on the apex seals lol

Engine has been ran before
It done 2 rounds of time attack apparently
It does turn over fine by hand and puffs and farts ok

It will be absolutely fine then bud, leave it as is and get it running.

If you have the second motor, with the cosmo plates , I would invest in getting it fully balanced and get the rotors scalloped

Will make it much more capable of turning 10,000rpm

The MSP is decent, it's just that when you want powaaaah you need peripheral exhausts. Lol

230hp NA is prety damn impressive although they don't brap
