Hi guys i know some of you don't think the JUN plenum is worth the money, but if we can get 20-30 more KW's at the wheels, it's worth it.

its on its way from japan, it shouold be here in a couple of weeks.

once we have the plenum and QF 45 throttle body on we are also going to put on a 4'' exhaust.

1. This GTR should go like the clappers.

2. It should sound bloody unbelievable.

i hope with these mods done it might be able to crack a 10 with no NOS and no sequential 6 speed.

the next mod after the engine work while probable be a OS 6 speed seqential, fingers crossed!

Cheers .

Looking forward to seeing the comparison dyno charts.:)

Myself, as all users... would be very appreciative if you can do a comparison thread. Before/after, all of it honest.

Im going to start compiling these over coming months into one sticky here so access too this info is here for everyone

As for before and after dyno's i will send you a copy once all is fitted up.

and as for the question on how much, lets just say i could have bought a pair of HKS 2530's for the money.

if i get another 30 kw at the wheels it will be worth it.

i would love to see the car crack a 10.

    • So..... it's going to be a heater hose or other coolant hose at the rear of the head/plenum. Or it's going to be one of the welch plugs on the back of the motor, which is a motor out thing to fix.
    • The oil pressure sensor for logging, does it happen to be the one that was slowly breaking out of the oil block? If it is,I would be ignoring your logs. You had a leak at the sensor which would mean it can't read accurately. It's a small hole at the sensor, and you had a small hole just before it, meaning you could have lost significant pressure reading.   As for brakes, if it's just fluid getting old, you won't necessarily end up with air sitting in the line. Bleed a shit tonne of fluid through so you effectively replace it and go again. Oh and, pay close attention to the pressure gauge while on track!
    • I don't know it is due to that. It could just be due to load on track being more than a dyno. But it would be nice to rule it out. We're talking a fraction of a second of pulling ~1 degree of timing. So it's not a lot, but I'd rather it be 0... Thicker oil isn't really a "bandaid" if it's oil that is going to run at 125C, is it? It will be thicker at 100 and thus at 125, where the 40 weight may not be as thick as one may like for that use. I already have a big pump that has been ported. They (They in this instance being the guy that built my heads) port them so they flow more at lower RPM but have a bypass spring that I believe is ~70psi. I have seen 70psi of oil pressure up top in the past, before I knew I had this leak. I have a 25 row oil cooler that takes up all the space in the driver side guard. It is interesting that GM themselves recommend 0-30 oil for their Vette applications. Unless you take it to the track where the official word is to put 20-50w oil in there, then take that back out after your track day is done and return to 0-30.
    • Nice, looks great. Nice work getting the factory parts also. Never know when you'll need them.
    • Thanks @jtha7 I will have a look around tomorrow but it is a prick of a spot. These are some photos i tried taking
