Close. It's actually a mid 60's holden....and it's tight fit.

Height is probably not so much of an issue as ic pipework.

Mid 60's, mmmmmm EH perhaps?

I would run a 120 degree bend at the throttle body, that will avoid the cross over pipe behind the radiator. This one has the intercooler pipework running outboard of the top radiator hose. It is more common to run the intercooler pipework inboard of the top radiator hose as it lessens the sharpness of the bend at the RHS subframe.

Hope that is of some help.:P

So when does the factory plenum become a problem then?

If im soon to be running a GT35r on a HKS lowmount manifold with a 45mm ext. gate running 20 psi, would the std plenum still be good to use?

I think (may not be right :P) that it will be like in the region of 530 odd BHP?

*discalimer*- im not here to start a war...peace forever with the std plenum i say :cheers:

Yep.

I'm not entirely convinced thats going to work, but i'll check it out. I'd have to go outboard of the radiator hose because there's virtually no space anywhere in front of the engine (it's so tight that I had to get one of the pulley hubs machined off the harmonic balancer to fit).

Yep.

Yep, the red motor is bit shorter than an RB, the bell housing is a fair bit bigger as well. I drove an EH with an RB30ET in it a few years back. Went real well:cheers:

Ok, this is my problem, its going into a drift spec 180sx, i've moved the engine back into the bulk head to move the weight off the front and behind the axles but not really the main reason for doing this, i've got a front V-mount Greddy intercooler (i.e made room for it).

So basicly because the engine is far back the plenum is crashing into the strut brace and at the very front hiting the bonnet, i've got a S15 front end on the car and the bonnet sits lower then standard ect.

Need to sort somthing out as i don't have the time to make one that works.

now your going to say well get the bonnet to sit higer and make a strut brace that goes around it, but the biggest problem of all its in the way of the brake servo :eek:

as i say don't need it to be any better then the stock one as i know thats good, just not be any worse.

Thanx you

i know the problem you are having here is a pic of my setup it loks like we are both going the same path with the engine build and i was looking for a plenum aswell

my throttle body hits the bonnet to at the moment

but it fits the reason i want to move mine is that i cant fit any desent sized thermos cuz of the pipe work and i want to keep under bonnet and inlet temps down so i dont have to cross infront of the radiator and back over the engine

If you are really seriuous about drifting, an RB in a S13/14/15 chasis is not a smart move. It moves the centre of gravity up too high at the front (that's why it hits on the bonnet) so the change of direction induces excessive roll. Even worse, it moves the polar moment of inertia a long way forward, so maintaining a drift becomes very difficult. I am not a big fan of SR20's, but you really should consider your options.

If you have gone too far down the RB path to turn back, then the RIPS inlet looks to provide the best option for throttle control, which is what you are going ot need. It's not perfect, but if you have painted yourself into a corner you don't have a lot of choices. You will just have to be mindful of the differential tuning requirements of each cylinder.

Unfortunately SK I think i'm in this position as well....but i'll still check out your first suggestion. Damn painting myself into corners....

I understand were you coming from SK, and i've had this on my mind from the begining but this is something i really want to do, i had a go in a S13 with a RB25DET conversion and it really did make the front end planted at high speeds (noramly understeer) so i'm more then happy with how it will feel at the end of all this.

The engine is very low tbh, i've had to make a new sump for it as i've retained the stock RS13 crossmember and made very low brakets ect, but its just that bloody intake being so high.

My options were my CA18DET tunned up, or RB20DET tuned up, i hate the bent cam so it was close call between the two.

you do get feed up of changing the bottom ends on the CA :wack:

    • I’m not sure what happened I told them about sonic tunes free OTS tune and the next the I know .. I was booted..   To funny 
    • Yea - I mean I've seen my fuel pump which is decades old and uh, while I'm not saying this with real knowledge... but I sure get the ick at using anything in the fuel system that produced the state of that pump. Many years ago I went through multiple pumps (and strainers) before I dropped the tank to clean it out with extreme violence. I'm talking the car would do maybe 50km before coming to a halt, which resulted in me cleaning out the filter with some brake cleaner and going on my way. None of my stuff ever looked like what came out of your fuel tank. I don't think I'd be happy with it unless every single component was replaced (or at least checked/cleaned/confirmed to be clean here).
    • I'm not going to recommend an EBC pad. I don't like them. Just about anything else would suit me better. I've been using Intima pads for a while now.
    • Agreed, and in particular the earth strap that should go from the subframe to the chassis but it often broken or left off. There is a section in the R32 workshop manual you can follow for troubleshooting if you don't see anything suspicious, and depending where you are (there is no location on your user profile) you should be able to get your hands on a second hand replacement unit still if needed
    • Yeah they mention as a R34 for 2.5 Turbo...but then again thos "small" were also for R34 by that different site. But i look into it and that 310mm EBC is for R34 GTT. And by those you linked the specs are the same 🙂    EDIT: I found these on one site here: DBA 4000 series T3 DBA42304S They are 310mm...and it says are for R34GTT...are there good? EDIT2: ok they have pads too.  What "color" should i get for street use? I dont want/need some noisy ones...(and if they are not that dusty that is good too)
