Hello, i want to fit a Cosworth YB engine into a rwd Opel, but don't really know what type of cosworth engine to go for. Can anyone let me know which to purchase; don't need or want anything over 300 bhp or so. Therefore would a standard engine with a chip in the ecu have much bhp, or big turbo wee turbo. What pitfalls could i find with YB engines....

Any help would be much appreciated ... Brian

You would be FAR better off with a C20LET vauxhall engine IMHO

Or the AUDI 2.0T engine.

Big lack of readily available RWD boxes for those

And dearer to get parts for than a C'LET to be honest, but fundamentally yes thats also a good choice in terms of making 300bhp reliabley and cheaply without paying "cossie tax" on the engine and bits in the first place.

Unless there is some specific reason it HAS to be a YB?

Stavros

If you want 300bhp and RWD surely you just go get a S14 200SX engine/box/ecu?

Easy, cheap, reliable, 2litre turbo, job done.

You mean 1.8T?

Nothing a bellhousing adaptor plate wouldnt solve I wouldnt of thought!?

Chip

iTrader: (3)

Yeah, thats a great option, the SR20



I assume me meant a 20vt and it was a typo

Chip

iTrader: (3)

A bit more to it than that, like a clutch for starters, but yes im sure there are options, but new adaptors tend to be dearer than old standard boxes if that makes sense?

Jay,

use a old passat rwd box straight on

Chip

Indeed, although that falls under the not readily available bit of my post IMHO, well relative to trying to find the box from a vauxhall omega which are worth next to nothing and can be bought every single day with ease

But yes, if you really want the 20vt motor, im not saying it cant be done, would be nicer to have a Opel engine in an Opel car though is my logic for suggesting the C'LET, well that and it does the job of 300bhp or thereabouts SO well.

JUST WANT A COSSIE TURBO, I ALREADY HAVE 2 C20XE'S IN BOTH OF MY RWD CARS, ONE WITH 45's AND ONE WITH JENVEYS... THE C20LET DOESN'T LOOK THAT TIDY WHEN INSTALLED, AND A FRIEND HAS PUT A 180SX NISSAN ENGINE IN A MANTA, SO QUITE LIKE THE IDEA OF A COSSIE TURBO...

WAS HOPING 1500-1800 WOULD BUY ME ALL I NEED FOR THE JOB. PROBLEM IS I DON'T KNOW ENOUGH ABOUT YB ENGINES...

Stavros

Passat RWD box? Passats have never been RWD.

foreigneRS

for 300 bhp, all you need is any of the yb engines on a std turbo and injectors and the right chip (NMS gunship for L8 ecu or similar).

there are other ways, and for 300 bhp i would do it (and did do it in my estate in sig pic) by using 'dark green' injectors as they have more capacity and don't require a higher fuel rail pressure and can have a high mid range boost spike (in conjunction with a 3 bar MAP sensor)

Chip

Yes they have mate, but like I said before, not exactly one in every scrapyard like an omega!

Some volvos (760 iirc) share the same box.

Chip

iTrader: (3)

You wont buy a cossie engine/loom/ecu/turbo/clutch/flywheel/box/manifolds/sump etc for 1500 IME, although you COULD get a LET and a R28 omega box setup complete for that, lol

Jay,

that is true fitted 5 over the years the last one came from germany out a 96 18t passat and we went to fetch it

Stavros

Ive never seen/heard of a standard RWD Passat?

They are longditudley mounted engines, but FWD.

Details please Chip/Jay.

bud-weis

The guy wants YB....stop trying to fob him off with Vauxhall shite

although to be fair the budget will need stretching as the engine alone would cost that ( for a decent runner.

A standard T3 equipped engine will do 300bhp all day long

if budget is a problem then i'd go jap like Stav has suggested.

Stavros

Yup, all day indeed, an entire 24hrs till the massivley overspeeded T3 shits itself

bud-weis

nah...it'll be reet especially if it's a 4x4 T3

Chip

iTrader: (3)

Details?

umm, they were sold in places like germany, they were shit, they were rwd, they never sold here, they are rarer than naked pictures of the queen, not really something I know much about TBH mate, just know they existed and the boxes are used on audi engines for v8 conversions, dont really know much else on the subject im afraid.

The Guy asked a simple question and it took 11 posts till someone actually answered it.

bud-weis

blame chip!!

for Ł1500 though i'd only expect you to be able to afford a decent running engine ( not a rebuilt one though i wouldn't have thought)

on top of that you'll need a loom, an ecu and a few other bits and pieces.

Stavros

Ages etc etc?

Cant find a thing googling RWD passat?

Even the Passat Wikipedia pages dont mention them and there loads of obscure facts on them?

foreigneRS

i answered it in post #14

I know but 2 of the posts where by brizer and I didnt count yours

foreigneRS

what about the gearbox from a posrche 924 or something? they used an engine from a VW transporter that may be similar bellhousing, or did they have a rear mounted gearbox on a transaxle? bit beside the point, as he wants to use a YB

Buy a rotten saph with decent running gaer if you can find one and then you'll have everything you need, they can be had for under 2K if you hunt about

big_wig_074

just buy any pre EECIV cossie engine (small turbo escort cosworth,has different cam cover and management) but with a 2wd sump,so easier to source a 2wd i would have thought,with its weber marelli management,doesnt matter which one,then get a stage 3 chip off someone reputable (Motorsport Developments on here are good),a 3 bar map sensor and a set of dark green (bosch injectors with part number ending in 803) injectors,and away you go,standard clutch will take the power,as will a t5,no probs,300-330 bhp depending on 2wd or 4x4 engine.thats it.done

Chip

iTrader: (3)

Umm, 80s, no idea where they are on the net, if you cant find them then I probably cant either as im sure your google skillz are as good as mine, maybe they were called a differetn name in germany like novas which were corsas in germany.

Jay,

iTrader: (4)

up to 94 mostly in germany they were mount latitude only a few made it in to the uk

foreigneRS

big wig, without upgrading the turbo, that is only a stg 2 and will not make much more than 300 bhp without seriously overspeeding the turbo

Chip

iTrader: (3)

As late as 94? wow, didnt realise that.
I think you meant mounted longitude though mate, lol

Jay,

iTrader: (4)

yeh tired lol been up since 4 am lol
