This is the thing - my shitty vauxhall/opel maniac friend iz ragging me again about the toughness of the opel engine(especially C20XE) and hoy much better it is than the F7P/R renault engine. Today he showed me a vid of a vectra 2.0 16v stock turbined(stock 204 bhp) that was on 1.6 bar boost with everything standard on the engine. he said - standarten dvigatel izdyrja do 1.6 bara boost - reno dvigatelq shte izdyrji li tolkoz A? <<< which means "the standard engine boosted to 1.6 bars - will a renault engine withstand that boost?"
So please help me by shutting his BIG SHITTY mouth!

and its a std turbo engine and the f7p/r is N/a so different applications!

Yes yes, but I ment the std renault turbo engines.

Might want to take a look at the Nissan 350Z's engine :) That can be turbo'd and is renault/nissan thingy.

Not sure what modern renault engines are actually turbo'd though.

BTW. 1.6Bar (Slightly over 23 PSI) is a hell of a lot of pressure on a std engine. Not sure how long it would last.

I was thinking about R5 or R11 or R21 turbos, we're talking about the old engines till '91-'92

Pretty damn special 'stock' turbine if it can maintain 23 psi! Would have to be a fair bit better than a sleeved T28 to manage it.

My point exactly! I'm thinking that he is lying "just a little bit" :)

I thing the "F7R" is much better of "C20XE" (hlopel engine) :D :D

But the "hlopel" engine pretends to be very tunable with the std parts inside, I think that they withstand to about 250 bhp according to the maniac's words...

decent cam, intercooler and T28 turbo withthe appropriate fueling mods to the carb and with 23psi on stanard internals the R5 c1j engine will do 220 horse approx.
And itll drop straight in a clio.
however the jetting for a carb to run that boost will eat your wages in fuel.

it takes 1.6 bar to make 204bhp?? says it all! lol
you run 1.6 bar through a cvh 1.6 motor and you would get that!!

Redtops are stonking engines, and so are f7 engines! any engine that can take abuse from all of us on here must be pretty bulletproof!!

Didnt know they made a redtop turbo vectra anyhow?!?!

The new megane sport is turbo'd ...

Get the specs of that one! :)

no no no, it runs at 7-8 psi stock and then it is 204 hp, but they have boosted it to 1.6 bar.

my Friend read into getting one of these engines to put in a nova, turned out that when you wanted anything more than 250bhp you had to change pistons.. imagine how much power the f7p would have if renault turbo'd it from day one :lol:

Is this regardig the F7P ? or the vauxhall shit?

my f7p did 217bhp at 0.6 bar on stock internals, thats the limit of it, boost more on std internals it dies

as for proper out the factory ones, as said the c1j r5 gtt lump can take over 23psi on standard internals, for a bit :lol:

At the wheels or at the flywheel?

Coops

flywheel that was mate, 176 at the wheels, its now running same but with wossener pistons and boosting to 1.05bar, not sure what its putting out fully but when i rolling roaded it last at 0.8bar it put out 190bhp at the wheels (228 at the fly)

will run 500bhp on stock crank. 300 bhp on stock rods at stock revs.
piston are great but because there higher compression won,t work in turbo configuration.

Great :) could I read these stats somewhere in the internet? MAXIBOY where do you know that from? I\m not trying to qustion the truthness of these facts, I just want to shut the vauxhall loving mouth :)

just what i have been informed from some of the big tuners that run big boost turbos.

have seen stock crank and rods run at 378bhp....

It should take 23psi all day long if the engine is set up properly.
no problem man!!!

this is tha F7P right, what about the F7R?

i'm have a F7r in the making with low compr pistons and stock rods

what can i gain at 1.1 Bar?

I was wondering What's the compretion ratio on a valver?

Standard compression ratio in an f7p is 10:1 as i understand, not sure bout f7r's

f7rs run 9:2:! think. n y turbos runnig them on low boost 4 200hp
my m8s valver 1.8 is runnig 268. with out forced induction

dodgy RR, even the greek built F7R with 8 injectors, bodies, forged internals and high comp pistons, oh and a 9300 rev limit only made 240bhp iirc, no way could you get 270 on std compression

sorry f7r, bloody edit button, where is it :roll:

not disbelieving but would love to see the rollng road graph at thats as much as full works 2.0 lumps where making
