The Poor Mans Non-Sequential Setup

[danny_m94]

i just wanted to let any1 that aint already realised when doing this mod or plaining to do so the guide mentions removing pipes from the pre control solenoid it mentions the location onthe front of the uim but says it is the passenger side solenoid . I may be wrong but this guide is based on an left hand drive car so its the drivers side on jap and uk spec cars. some1 please correct me if im wrong

Iv just notice this threads recent activity and i agree with Mark. Seq is better theres no doubt about it.

We\'ve owned various FD\'s with twins, singles and uprated twins at the same time. A car running twins in seq form (running properly) is so much more rewarding than driving non-seq or single.

Comparing twins in seq form, to a small single/non-seq, jumping in one straight into another, the twins will always be the one that feels quicker around town.

The only reason people change from seq to non-seq is either:
Boost problems caused by the stock solenoids (Troubleshooting doesn\'t have to be expensive or tiresome if you do it properly by ditching the stock rats nest)
Fuel Economy (Your driving the wrong car)
Or they prefer the non-seq power band due to the lack of the 4.5k 2nd turbo kick (Because they cant drive:Giggle)

Someone mentioned that most people opt to go single. Yes purely down to the horsepower factor.

However people have started realising that staying twins by getting uprated ones is the way forward. I know I have owned all variants. Those who have been in my car have all said the same, with 2 of them now driving uprated twins in seq form.:wiggle

In no way am I saying twins are without fault. Yes they give off plenty of heat and yes they have common boost issues but when its right its right!:driving

i have to agree i went non sequential for a week wasnt a big fan put my car back at the same time as new downpipe and im in love. Currently watching the minutes tick away till i can finish work and drive her again.

ive jsut done this and have a huge boost leak from somewhere??? ive checked and double checked all the hard pipe connections but cant seem to fathom it out!?

[pearl_rex]

problem sorted out now, and i can honestly say im never ever going back to sequential!!!!! ive never felt anything like it when you plant the noisy pedal!!

Interesting thread, ive always been a fan of sequential turbos and on all of my FD\'s i have gone to great pains to make sure they work properly. If there are no boost problems the transition between and first and second turbo will be almost seamless.

Sorry to dig up an old thread. I\'ve just done this due to having problems with the standard set up. Everything seems fine but I seem to be only seeing 5psi boost max at the moment.
 
I can\'t find a boost leak any where, and a few peeps have had a gander too, and are a little puzzled too.
 
I\'ve gone the full hog with minimal solonoid option. Only solonoids that are still running hoses, are the wastegate control and purge solonoid. Turbo control flap wired open, and actuator flap rigged open and actuator hose plugged.
 
Waste gate controller solonoid top connector is hosed to the wastegate, and the bottom is venting to atmosphere. The only thing I am ot sure about is which way the vaccum pulls on the 2 wastegate nipples. I presume the pull is from the hose that connects to the turbo body (or turbo housing bracket).
 
I am going to double check the y pipe as I am not too sure if I missed a nipple under the CRV. Will post back if I have and feel like an utter pleb!! lol.
 
If anyone that has boost issues since doing the non seq conversion, and then found the fault, can you please post up, so far I know there are at least 3 of you that have posted in this thread with similar boost issues! Would be most grateful!!!!

[arrouk]

have you remembered to put the pills back into the vacuum hose to the waste gate solenoid?

hth

[Looney]

just checked the y pipe and this was something I had sorted whilst on the job as it was common sense to plug them together. Phew, but still don\'t know whats going on with it...lol

[Looney]

not checked the pills tbh. I\'ll double check they are still there... you\'re on about the hose from the wastegate to the solonoid?

[SmbFD3S]

You haven\'t replace the hose tho have you Len so they should still be there....
 
5 psi is wastegate spring pressure isn\'t it?  Just sounds like the solenoids not controlling the wastegate to me :/

[Looney]

You got a spare wastegate controller? You watch that was the last bugger to have failed and still causing problems...
 
No I haven\'t changed the hose iirc, but worth double checking just in case.
 
Just checked on one of my diags of the turbos, the flow would be from solonoid to wastegate, to turbo housing. So would suggest that I have a blocked pipe, or solonoid is stuck shut.
 
Anyone got a spare wastegate control solonoid I can borrow to check it with?
 
I\'ll double check the hose between the solonoid and wg tomorrow to make sure it aint blocked.

[SmbFD3S]

Well assuming the turbo pre-control solenoid is the same just swap them over mate and see what happens as you dont use that one on the non-seq setup i dont think ?

[Looney]

yeah I\'ll give that a try see what happens. I forget that about most of the solonoids, I am used to follow by color, as they are marked to make sure the correct plug goes to the correct solonoid on the standard setup.

Hi mate. Sorry things are still awry. Not my speciallity this. Does sound like the plumbing is not flowing right (way wired or dodgy link I wouldnt know), but I guess someone who\'s done NSq. has checked (1st idea..i.e. something perhaps needs plumbing different or removing??).

I can give (for you non gratis) the solenoid if you wish to try...better know what it looks like though! lol.
