Possible Power Output Of An Rfv

[sub205 5]

Hello,

 

as some know, i recently pushed an RFX 2.0 8v from 121 to 157bhp using standardtechnics and a good camshaft.

Does anyone know if a RFV 2.0 16v 132bhp is equally complicated to tune?

 

What power output have you achived from this engine, what steps have you done?

 

i can get such an engine for small bucks, but dont want it if the end result is just 150-155bhp, then i can stick with my RFX.

[welshpug 1,661]

150-160 should be very easy, just bolt on RFS manifolds and camshafts.

This doesn't help you much on your quest, but what exactly was done on the RFX since I have one extra that I got for free??

 

RFV engine is if I'm not completely wrong pretty much the same, at least head wise, as the S16 engine. So you should be able to get 170 pretty easy by changing inlet manifold to GTI-6 one, a pair of camsafts and a re-tune. RFV inlet manifold is pretty useless from what I've understood. <- All this isn't probably 100% fact, but this is what I remember and have understood.

 

edit: was bit slow..

The RFV has a fantastic cylinder head, but with very small duration cams. So just bolt in some new bump sticks (GTi6 type), new ECU, bigger injectors and away you go! I'm just about to bolt an RFV head to an S16 block, along with GTi6 exhaust and shortened Mi16 inlet manifold. Looking for around 190hp. Should be fun.

what cams is that going to be using Pete? far more scope with that bottom end for lift @ TDC than with RFS pistons, ever so slightly more compression too.

that sounds good!

i can get a decent engine for 200euros, 109000km, with all necessary parts.

although i just finished the 2.0 8v this sounds like a great idea to gain more power, the 16v is just better, especially at higher rpms ...

but i think i'll use some variant of the s16 with switched manifold because i like the lower rpm power output.

I presume that'll be with mappable management too Pete?

 

 

For those that have no idea what the hell all these codes mean;

 

RFV = XU10J4R is regular spec 306/406/Xantia etc 2.0 16v engine. 1997-01 iirc

 

RFS = XU10J4RS is GTi6/Xsara VTS engine, 1996-01 iirc

i'm running a custom megasquirt 2 right now with a marelli loom and peripherals, so this should not be a great problem.

 

i wonder why there are 2 types of 2.0 16v with 132bhp:

- 406 / xsara XU

- 206 s16 EW

 

anyone knows where the EW engines sit in and what their 3-letter-code is?

[Paul_13 212 1 Cars]

I think the engine you mean (206 S16 EW) is the 206 GTI engine (Not the 180 version).

 

These are quite a bit different to the XU 2.0 16v, I think it has a multiplex loom but I may be confusing this with the 180 engine.

 

 

Just to say the 2.0 16v XU engine comes in 306's aswell

 

And the 206 EW 2.0 16v (136bhp) engine comes in the 206 SW (which is an estate version)

Our 'GTi' 's are European 'S16' 's Paul.

the engine i'm tallking about is from the 406 and the head has the rounded top like the 206 engine, but the 306s16 looks more like the mi16, or am i confused?

[Baz 421]

You are confused.

 

The engine from the 406 may look similar to the 206 one, but they're not the same i assure you.

 

 

And the 306 S16 engine is different again.

Edited January 21, 2010 by Baz

[sub205 5]

ok, now i remember.

 

the 306 s16 looks more like the mi16 and has ~150bhp (XU10J4)

the 306 16v cabrio with the 132bhp engine has the camcover looking like the 206 s16 (XU10J4R/RFV)

the 306gti6 looks like the s16 (except for the inlet manifold) (XU10J4RS)

 

correct?

[welshpug 1,661]

A late 406 does actually use the EW engines.

 

206 DOES NOT use an XU engine.

 

306 S16, IS an MI16 engine.

 

306 GTI6 looks like an early RFV bar different intake manifolds.

Actually, late 406's had EW series engines, just like 206 GTi's did

 

They changed from XU to EW engines around 2001 I believe.

[Baz 421]

Ahh, interesting!

[sub205 5]

Ahh, interesting!

this one is a '96, so its an XU.

i dont know how conversion complexity raises with EW-engines?

Some regrinds I've got laying around:

 

Inlet

228 deg @ 0.050"

0.438" max. lift

 

Exhaust

215 deg @ 0.050"

0.380" max. lift

 

Aiming to keep CR no more than 11:1. Using a Haltech Sport 1000 ECU and 270cc injectors.

stock cr is about 10:1 i think or?

 

any data about xu10j4, xu10j4r, xu10j4rs is welcome. so i can compare everything

[welshpug 1,661]

the 16v XU's are all 10.4-1 apart from the RFS which is 10.8 and the DFW 1.9 Mi16 which is in the 9's.

[carbers205 1]

EW engines have different mounting points from what I remember so its not as straightforward as changing between XUs

[sub205 5]

my only concern is that this engine should have more power than my current 2.0 8v ... i've never driven an mi16 with 147bhp, but my 8v is measured with 157bhp. thats more than a standard s16.

 

has anyone dyno results from the 2.0 16v series and the parts changed?

[welshpug 1,661]

what's your torque curve like?
