Yea wot kinda increase are u looking at with just the SPI changed? i know it wont be much but are we looking at any increase?
btw, does anyone knows the diameter of the shaft that comes in the laguna 1.8 TB? Need to check something. It seems that some R19 also had the same engine with the same SPI..... if this is true, then its easier for everyone to find the so desiered TB.
and, was the laguna 1.8 1794cc? Thats the R19 cc.
Burte..........
donno mate
Quote "renault laguna 1.8 single injection unit "
im not much of a grease monkey, but im guessing this and the throttle body is what u were taking about early in post? or is this uni the throttle body?
worth picking one up and replacing it if i can get it for £10?
Ok im still lost here i need a defination of the difference between a SPI injection unit is and throttle bodies
a bloke lost bak end of his Laguna other week, i remebered this post, and he said i can any of the parts of his engine... so..........
what do i need? and is it worth swaping onto my RT? or will it be a waste of time?
Youve read through the post right?
You need the SPI injection throttle body off the 1.8 SPI lag.
SPI throttle bodies look the same as the one on yours with the constant injector aiming at the throttle plate, hence single point...only 1 injector. Throttle bodies are where each inlet tract is controlled by 1 throttle plate (butterfly) each, so you have 4 indipendant runners, one for each cylinder. MPI is where there is 1 throttle plate (butterfly) controlling airflow and 4 injectors placed in each inlet runner, 1 per cylinder.
yup i have read the right post.......... this one..........
and i get the difference between SPI & MPI
but my question was for some1 to explain to me........

Are these different things? or the same thing?
sorry for being dense but im not going to know till some1 explains to me. and the other question.............
is this worth doing in your opinion?!
and yes i have read through the whole post, but never get a striaght answer when i posted before.
lets say i have a SPI throttle body from a 1.8lag in my right hand, and to my left if my lil 1.4RT, should i borther doing the swap?!
or is it not worth doing till got the head, Ecu done etc? if i was to do them.
an energy engine is a 1.4. the rsi and 1.8rt are f engines and multipoint injection. the f engine is in some older volvos but it is a renault engine. think renault and volvo must have had some deal going at sometime as they used the f engine and renault used the volvo N7Q engine in the laguna and safrane.
ooooooook then i suspose i will just knick the parts and keep em in my garage for time being then.
an energy engine is only a 1.4 or 1.2. the laguna 1.8 single point injection was an f engine but the throttle body can be easily made to fit the energy engine inlet manifold. later f engines like the in the clio rsi were multipoint injection. do you get what i mean,i tend to waffle sometimes?
how much is a Tubular 4-2-1 exhaust manifold gonno cost me for me clio?
a spi has a throttle body with one injector in it and a throttle butterfly.it is bolted to the top of the inlet manifold on the energy engine. this supplys all the cylinders as a carb would.
an mpi has an injection rail with 4 injectors on it so you have 1 injector per cylinder. each injector injects fuel into the inlet manifold just before the air enters the head. the injection rail supplys fuel to all 4 injectors.
lol
i never the asked the difference between SPI and MPI its pretty obviously, i just wanted to know was it worth it.......... now look what ive done
For whoever asked earlier what a 1.4 energy MPI engine looked like...

Thats an E7J-780 engine... 1.4 8v MPI in a 1999 clio

thats a pic with the airbox cover off, you can see the throttle body, which is sandwiched between the airbox and in the inlet manifold.
i thought i had a pic with the airbox off completely, then you can see the whole throttle body, and fuel rail and all the injectors etc.
