So an interesting idea that we saw on the TEPS M35 site before it went down was to install a spacer to slightly increase the length of the runners. The thought being that it may improve low-mid range

What do you mean "follow through with this"? I sold a number of kits with the phenolic spacer and I think Andy and Craig did as well. My old M35 is still alive and kicking on the Mornington Peninsul

Back then there was a tiny market for M35's and outside of some Japanese tuning houses (click my sig for one that is a good read) nobody touched M35 development except for what you find here or on the

PM me your VIN and I will see what yours is compatible with (VQ25det is the same as VQ23de only :/ ).

I am sure I could make one up for you if I had a gasket.

Have you put a plenum spacer to increase the volume of your plenum (should possibly be the same as VQ35de)?

Nah haven't tried a plenum spacer, where can I find those?

I am pretty sure that your plenum is the same as a V35/G35, but I'll check tonight just to make sure.

If it is the same, you can get one from the US (eBay is easy) OR my mate has an aluminium one he made for his V35. I will talk to him tonight and see if wants to let it go.

Isn't it better to have one that doesn't trransfer too much heat to your intake plenum?

Yes... with a runner spacer it definitely is.

With a V35 plenum spacer it makes no difference as the spacer is installed between the top and bottom sections of the standard cast alloy plenum.

lol... thanks mate... although the torque increase is there I have yet to dyno it.

Would be tricky to get an accurate comparison though as the engine needs to be cold to install the spacer kit.

Ryan, as per the first post... the original was 17mm as that was the size aluminium we had access to. It was modelled of the 20mm aluminium TEPS unit. When I switched to Bakelite, I wanted to go with a taller spacer to see if there was a noticeable performance increase (unknown) and also so it could soak up a bit more heat from the engine due to the larger area.

So does that mean if a 30mm spacer would fit under the bonnet you'd do it?

I'm thinking if the engine cover fits back over the engine with the spacer installed, I should be able to fit a spacer and a strut brace no problems. Hopefully we'll find out tonight :thumbsup:

i dont care what cam tells you.

the cover DOES NOT fit back on with the spacer.. it touches the bonnet

Aaron, go talk to Nick "nickcorr" about that.

His has been installed a lot longer than yours.

I'd certainly try it out.

Could do it too - the PM35 bonnet has a lot more clearance than the NM35 bonnet.

Are you physically unable to close the bonnet or is it that you think/know/hear its touching once it does eventually close?

well last time me and scott tried my fron bar was off.

i could clearly see it touching. and it hack up the foam on the bonnet.

      RB26DETT Sketchy boost mod?

      By GTSBoy · Posted

      There's restrictor pills in the stock boost control hoses. That's how they set the amount that was bled off and hence the "high" boost setting. The usual mod in the day was to remove it and send the "high" boost setting up to about 14 psi.

      Thanks Duncan, that's the best info I've read. Furthermore after learning about the PCM programming side controlling the factory boost solenoid, the purpose of the solenoid is to "bleed" boost when pin 25 is earthed, thus allowing spring pressure in the wastegate actuator to overcome diaphragm boost pressure, thus closing or reducing the position of the wastegate flap creating more boost as the turbo is able to spin faster. It's pretty cool to see a designated Pill to do exactly this, would have liked to have seen it with a tiny filter over the end for those moments in vacuum.  The constant bleed pill has now been removed completely from the system and solenoid boost control has been restored once again.   Case closed 😂

      Cas issue

      By GTSBoy · Posted

      The wideband reading is meaningless if it's not running. Why are you using shitty old sidefeeds on any engine, let alone a Neo? What manifold and fuel rail are you using to achieve that? Beyond that, can't help you with AEM stuff as I've never been their ECU/CAS combo.

      Manual boost controllers (where a little of the boost was bled off) were quite common back in the day, because they were cheap and easy. Generally they had a manual adjustment screw rather than being fixed like yours. Down side is they always bleed boost, not just when you want them to so an electronic boost controller that uses a solenoid will have less lag.
