My RB26 powered JZX81 Chaser - Page 35 - Drifting forum

Weather forecast to get warmer over the weekend

Stavros · 20-12-2007, 18:52

Yeah, well forcast I saw said it would be from today!

Ive just posted on GTR forum asking if, with the throttle stops adjusted ok and relevant pipes blocked up, RB26s still idle with all the ISCV crap removed, as if so, that makes life in future LOADS easier.

All other cars ive experienced do just fine apart from for first 30secs or so when dead cold, so dont see why 26s shouldnt.

They sure do when converted to single throttle with all the idle crap in the bin.

MJG · 20-12-2007, 19:00

I know the idle control valve on my BMW doesn't seem to make a difference apart from, as you say, when first starting it. No biggy

Stavros · 20-12-2007, 19:21

Yup, on my Cossie I didnt have one, as, being a man rather than a lady, I replaced it with a massive Mountune AntiLag valve.
All it did, even on proper sub-zero conditions on a cold engine, was stall first time if didnt use throttle.
If used throttle or just restarted it, it was bob on.

But RB26s are like voodoo, so frick knows, worth checking, lol.

Reckon itd save about 20kg too, the idle crap is enourmous, AND itd mean I can take head off without removing manifolds in future too, like on all good cars.
Itd actually make me un-hate RB26s a bit.

DRIFTR · 21-12-2007, 02:06

Talk about talking

If you want it sorted bring it down, i have done enough conversions in the past apart from a RB in a Chaser

, An S14 diagnostic plug can be hard wired in the back of the ECU plug to have full diagnostic/data logging and component testing. The R32 GTR ECU can be remapped and we can hold the engine under load on the roller's to work on the missfire.
Being a HKS dealer we carry the metal inlet gaskets in stock.
Any other RB related parts would be in stock new/proven

Also be interesting to check out the JDM wiring

ant · 22-12-2007, 13:54

the jdm wiring is a jdm bodge

Stavros · 27-12-2007, 14:40

Not much of a update at mo as ive got the Flu, but im gonna get cracking with getting the inlet off in a min, and order some uprated inlet manifold gaskets tomorrow if anywhere has em in stock and can get em me ASAP.

Slight interesting update for Doz and a few others who know about it as in between mega hadaches and feverish sweating

from this fantastic Flu, I did some measuring....

That engine I have is 25in wide at its widest point.
Engine bay is 33.5inches wide at its narrowest point, giving a 4.25inch gap each side.
Exhaust ports are approx 2.5in inside the overall width per side
This gives approx 6.5 to 7inches gap each side for the manifolds I have.
Each manifold is 5inches at its widest point, and sits at a slight angle.
That gives 1.5-2inches space each side.
Basically, it would fit, lol.
Think would have to go to a pedal box as albeit small, the servo would prob get in the way, but the turbos at least wouldnt, as they sit forwards of the engine, where the may is massivley wider.

Anyhow, enough of that, time to sort out present problems, ie this POS running on 5...

Karan · 27-12-2007, 15:34

Hi stav sorry to hear u r still pissing around.... as i spoke to u a few months back... we are still pissing round with the rb26 in our r32.... first boost control issues, turbos blowing oil into inlet big stylee as well as some other probs.

good luck

definitely rb26 voodoo LOL

Hammond · 27-12-2007, 15:39

Can't believe you're still having probs man!

CA it

Stavros · 27-12-2007, 16:52

Its been slow and annoyingly gay progress, hampered by having to do it outside, and lately me being ill, but now its down to it being almost deffo the inlet gasket between the throttle and the head.
very bad leak post throttle on 1 cyl only making the mixture so lean it wont even ignite at idle, but the extra fuel you would get off idle explains why it tries too if you give it a bit of throttle.

how the frick you are meant to get to half the bolts under the plenum is beyond me tho, i can see why some people remove their engines just to change the inlet gaskets now.

if its not that, then frick knows.

topi · 28-12-2007, 17:10

Ah so hopefully that will be the cause of all the gayness?

If I was closer, and knew what I was doing with such engines, I'd offer a hand.

Stavros · 28-12-2007, 18:11

Well, despite Flu, and rain, and gailforce winds, we been trying to get the inlet off today.
And failing.
Maybe its because its in a Chaser enginebay (Clarkey and Ant mentioned there was less room it seemed, i wasnt so sure, but maybe they right) but im fricked if I can see how you meant to get any kind of purchase on the rear 3 bottom plenum bolts with any kind of tool without taking the engine clean out.
If the plenum was flat its be ok, but each runner fans outwards, so you cant just stick a socket straight on em, not to mention the idle control stuff blocking you.
Do you have to remove a load of idle control stuff first?

I see now why some people remove their engines just to change the inlet gaskets!

If anyone has done or can do some kind of step by step guide thatd help, thatd be good!

To me anyhow, as it stands, it looks like it might be an engine out job to do these!

Good old engine conversions eh, GREAT ideas!

Karan · 28-12-2007, 18:20

just remove everything in the way... then jack the car up really high and try doit from underneath....

neeesaaaarn engine bay design is shite

I was told that can do it all from the top and underneath doesnt help you really?

The main shit in the way is the idle control crap, and dont know if thats removable before the plenum, dont really look like it is!

no, its still a horrendous design to work on in a nissan bay, but its as bad or worse in a toyota.

gtst lad · 28-12-2007, 18:26

tbh you'd be best of just biting the bullet and pulling the engine and box out for the sake of how long it takes.

At least then you'd beable to put everything together perfectly! imagine trying to torque the plenum back up evenly when it's this much of a bitch just to get off.

Alex B · 28-12-2007, 18:39

Getting underneath won't help at all.

Do you have a worrkshop manual on cd? It shows you exactly where the bolts are, which helps a bit, after that it's just a case of finding the right mixture of tools to get on the nuts and bolts, no easy way to explain the job!

Alex B

gtst lad · 28-12-2007, 18:50

i've got the workshop manual here if you want me to upload it and post a link.

Stavros · 28-12-2007, 19:08

I know where the bolts are, we spent ages working out the best combo of tools to get a socket on em, but still, it dont really sit on em well at all, the plenum shape means its precariously close to rounding off the nuts, so didnt push it too much.

Dont think them diagrams tell me anything thats gonna help me

To make up for it im gonna go out and get totally shitted tonight, Flu or no Flu.

ant · 28-12-2007, 19:15

take the engine out, i did to do the cluch and inlet gaskets on my gtr, you could do it all in a day then
