i have seem this done on a lot of big power classics, anyone know the ins and outs of it, i assume its done to reduce lag due to less pipe work.

do you have to fabricate front mount pipes or a kit availiable ?
you you need to modify inlet piping ?
etc etc
trying to gather as much info as possible because its something im considering
i have a 1994 WRX 240ps

many thanks

Sounds intresting, is it just a matter of taking your inlet off and turning it all around?

 

£1,750 !.

 

pull your pants down, that is expensive!!

but looks

 

I think the main benefit is to get a bigger front entry turbo on mate, difficult to do with the V1/2 manifold, I am playing with the idea of raising it up but that wont help the piping issue or reduce lag though!

 

bloody hell that is expensive, Im sure I saw a kit including a huge FMIC and all the piping for 2k recently.

 

Thats a WRC manifold expect to pay good money.

Phase one manifolds need to have the TB flange welded back to front you cant just turn the manifold even though it is possible the ICV will fowl the bonnet.

You can make use in most cases of the existing FMIC pipe work.

You still need to ensure various other parts are modified to fit.

Nez-WRX not something that would be at the top of my list for where your at right now

 

Is it possible to simply turn the later manifolds then?

 

check out tsl website as it has reverse inlet manifold and fmic for 1355 plus vat.they say that the main benefit of fitting reverse manifold is to reduce lag when a front mount is fitted due to pipe work being lot longer than having top mount intercooler.

 

yes it is, infact im getting mine done along with custom fmic pipework and parallel fuel feed conversion at slowboy racing next week at almost a quarter of the cost involved in buying that wrc inlet manifold...

 

Hmm sounds interesting, I already have the parallel fuel rails, I ownder what the cost would be without that.

What do you hope to gain from doing it?

 

speak to neil from slowboy im sure he'l sort you out a good deal, itl'l be intresting to see the outcome as my car is quite responsive as it is, but i guess it does help with lag and spoolup

 

think i could benefit by spending the money else were to be honest, was just a thought as my manifold has to come off anyway due to a coolant leak from the n/s o ring on the coolant cross over pipe.

 

Might be worth a chat, Im not sure how much a reduction I would gain by doing it tbh, as I have a Hybrid FMIC and I think the way the piping is would barely make a difference.

The pipe that connects to the TB comes out of the inner wing right next to where the CAIK goes.

 

definately have a chat with neil because from what i can see your using a fairly large turbo on a 2.0 with a fmic, im pretty sure u could speed up spool up by a few hundred revs with a reversed inlet

 

Def worth thinking about, I really could do with having a couple of pipes made up so might be a good mod to do.

Are the IC pipe made on site there or are they ordered in?

 

Just had a thought, this will mean loosing the air conditioning wont it?

 

air con is overated lol

 

Hmmm, not sure ifI fancy loosing it though.

 

fit a roof vent then

 

see now, that's just removed my only excuse not to do it.

I think I will be making enquiries

 

Slowboy can fabricate the pipework from your existing setup if needed...

They recently done it on a friends type R with a 2.0/FMIC 20g setup, and the spool up is amazingly quick.

Lag is absolutely minimal between shifts and a definite improvement from before, it actually has less lag than with a VF23 conventional FMIC setup.

 

Then there is the weight saving aspect of no air con. Sounds awfully tempting, i will def be making some enquiries on Monday.

 

Speak to Mark @ Lateral about their awesome Custom FMIC, keeps pipework to a bare minimum and no cutting bumpers

 

I looked into going reversed inlet manifold a while back, but all the response I got was it wasn't worth the hassle for the gains so I left mine as it is

 

guys tracktive solutions are the men to talk to they do a kit and if you go to sso they been running rev inlet for years plus richard b is ex wrc mapper so win win he was talking about a new better quality item at this years sso so that should be good give them a try

 

stevebt, what manifold is that? One of those magnus ones?

 

Yeah but they take a lot of work to fit as they aren't just plug and play

 

Am liking that a lot, is that suited best to twisted turbo setups though?

 

It will and has been used in both normal and rotated set-ups with excellent results

for minimal pipework you may be best going rotated, but it won't be that far off if the turbo is in the standard position
