bought a project car (r32 gtr). finally got it up and going and its not hitting boost - at all

has hi mount t66 and external gate, boost tap, and power fc, stock bov (currently vented to atmosphere :( )

now i blocked up the bov's to see if they were leaking - still no boost

fiddled with the boost tap up and down - still no boost

rev the car, take it for a drive - wont make any boost whatsoever - not even 1psi

anyone have any ideas why it could be doing this.

only thing i can think of is faulty wastegate but when i had it off the car the spring in it had plenty of tension (gate was hard as f**k to push down)

please help :(

The stock bov should be Plummer back but if it isn't it only really effects idle etc it's not going to completely stop it boosting. And to address this issue I blocked it off. There's no funny sounds. I've checked te ic pipes but will go over them again as i may have missed something

No boost at all but still drives with power fc afm etc tells me there shouldnt be any air leaks.

Either turbo's not spooling or the wastegate is completely open which should still make some boost.

Take the wastegate pipe off and see if the exhaust is exiting it.

Is the engine timing and all the basics set correctly?

Has the power fc been tuned before?

Take the dump pipe off and start the engine. See if the turbine is spinning and increases speed with the engine rpm.

Are the wheels still intact with fins?

Have u tried a different boost gauge?

collapsed cat would still make boost, just not do anything with it.

Can you hear the turbo spool up?

Have you confirmed that it definitely isn't making boost and that the issue isn't with the boost gauge? Stupid question i know but i have seen it happen.

Put it on a dyno. you'd be suprised what you can see when you look at the engine under load.

doesnt cat a cat. rest of exhaust is fine. definitely doesnt boost, or even try to boost.

take it for a drive and it just climbs through the revs fine until you change gear. only problem is it doesnt spool 1 bit,

its as though someone is opening the wastegate as soon as it makes boost, but am 99% sure this is not the case (see posts above)

going to check the fueling of it today.

thanks heaps for input - any input is really appreciated at this stage :(

    • Personal experience. Those f**kers burn. And are actually a PITA to put out. Next time I walk down the back, I'll snap a photo of what the inside of the bonnet looks like when that thing ignites. PS, powder fire extinguishers are useless on that stuff too as it's fibrous and when it ignites, it starts to pull apart. And you end up just blowing powder through a sieve effectively.   Like the big thing is, if it's fire resistant, it's job is to stop what burning? The METAL above it? It's just to try keep heat off the bonnet paint work.
    • Oh man, sorry, $60.00000000... 😛
    • That's more or less what he meant. What it really means is that you do not have to go full crazy on the build. Don't need the best oil pump, expensive rods & pistons, big cams, etc. You can upgrade whatever you want instead of using stock level items, but you don't have to. Having said that - any time an RB is opened up, if anything is getting replaced, I think the opportunity should be taken to do all the sensible upgrades. Pistons, rods, pump, etc.
    • February update 🙂 We managed to get the very last 1/18th "Extra Scale" cars stock available from bookstores in Kyoto. These are actually the last ones and will not be restocked again! Hachette Collections Japan have not decided on a release date for these or other models in the series, so for the time being these are all there are available new.  These are showing up on Yahoo auctions at inflated prices already (especially the Celica and NSX) so get yours now at a very reasonable price before they disappear!

    • When you say basic rebuild, you mean an oem rebuild?
