Out doing a few bits on the cossie in the garage today, and started day dreaming about what you'd need spec wise and cash wise to acheive a 600bhp YB.

Mine at the moment is roughly 400bhp.... So how much further would you need to push to generate an extra 200?


My guess is a lot

As you said, a lot! Especially to a decent finish. Plus everything to go around it

Stay at your current Spec buddy for road car usage, it does get very costly else

imo the problem is there is virtually nothing on a stock cossie that can realistically handle 600 hp, its gonna be very expensive to do properly.

cossies are relatively light aswell which makes a 400 hp cossie a fast road car.
unless youve got Ł20k+ burning a hole id forget it or save and buy one built is the cheapest way as long as you buy right.

Your looking at over 6 grand in inlet / exhaust manifolds turbo management rods pistons and liners if you won't to do it right! The list is long and expencive lol
Not to meantion things like clutch gearbox diff brakes

Oh I don't want to do it, was just thinking what it would take lol!

In the real world IF I wanted that kind of power a jap car would be the way to go I presume

ajamesc

depends what you like lol
Yb's can do it and do it well jap stuff can be un reliable and expencive too biggest part of it is who builds and tunes its!
A 600 bhp yb is a massively fast car!

Forgetting price I think 600bhp is a spec most top tuners have a way off archiving easy these days?

Mine currently makes 550 bhp and 531 ft/lb of Torque i'd like to think it would make 600bhp with going solid lifters and bigger cams taking the limiter up from 7200rpm to 8500rpm.
Here's the current spec:
CGI 200 Twin feed Ex-WRC Block
10 Long Studs
Wet Nikasil Liners
Cosworth Racing Short Skirt Pistons 7.9:1 Compression Ratio
Cosworth WRC Long Rods
Mountune/Cosworth Crank
Oil Spray Jets
High Pressure and Flow Oil Pump
Wide Wing Sump with a Blue Sprint Sump Baffle
Big Ported Head 27mm Inlet 27mm Exhaust
Danny @ BlueSprint Super High lift Inlet cam
Standard Exhaust Cam
Hart Inlet Manifold
83lb Siemens Injectors
Tubular Manifold with 52mm primaries
GTX3076r Turbo with Tial .82 SS V-Band Exhaust Housing fitted with air to fluid cooler
100mm Airtec Intercooler

looking at power to weight an r32/r33/r34 gtr would need approximately 100 hp more to match a 600 hp cossie, but that being said the gtr complete driveline is leagues ahead and the stock driveline will take 700 hp at a push except the clutch obviously.
on a stock r32 gtr driveline on a twin clutch i have put down 0 - 60 in 3.3 seconds and 0 - 100 mph in 7.9 seconds and trapped 123 mph at pod all in car that cost me Ł10k built with a new tr racing built engine in that price aswell, the grip and driveline strength of the gtrs is my main passion for them. they have reported weak bottom ends but in my experience out of the 3 gtrs ive had so far the only one that had problems was a standard sump car that had a double capacity oil pump fitted ! imo its build issues alot of the time just like my 2jz engine built by monkeys !

in gear on the move on the road though with a cossie being just 1250 kg and if its rwd aswell will be a seriously fast car if you can get the power to the road that is.

so far i can find nothing better than the gtrs for price compared to overall performance/tunebility.

booner999

I have a rwd escort cosworth and it goes like fook. As said it does not weigh too much without the 4x4 and your biggest problem is putting the power down

Sounds daft this but i think that's part of the fun of owning a cossie, i.e struggling to get grip down etc, the rattles, smell of fuel in car etc

Unless I'm just strange and getting old

Rod-Tarry

My 660bhp conversion was my best road Spec. However you would need a TKO conversion , Jag/Supra diff , rear beam with chassis connectors decent suspension kit & mods to take wide tyres. Drive Shafts screw like coke cans at that Power/Torque & its still a prob on mine. The prop also needs extra support/bearing at these Power level or if used in anger will cause a prob. Beyond that Power the problems simply multipy x100 as ive found out been since Feb 2006 on the problems but maybe just maybe late 2013 will see a 800+ YB that can be used as a normal road car & have a 10k+ life.

Staffi

iTrader: (1)

That sums it up pretty well Rod imo

Rod, what turbo were you on on your 660 setup?

WongRS

iTrader: (11)

Agree'd. Mine was leaving a set of 11's @ 70 mph up the motorway going to classic ford this year apparently, and i wouldn't like it any other way, it's still accelerating like scolded cat and it makes it so much more fun!
And the smell's, as you say, love it.

Billy_RS

iTrader: (5)

So basically.... a lot then

Where is the line drawn before everything need upgrading?

Surely after 20+ years of the YB engine tuners must of found out where the limits are on these engines.

Do you get to 450/500/550bhp or similar ft/lb torque and the rods/pistons/block/crank/gearbox/driveshafts/prop/diff/clutch need replacing?

Where is the best place to stop?

JamesH

iTrader: (21)

The best place to stop, is where you are currently

380-400 plenty enough for where I drive ... Any more and I would be dead lol..

Just a shame I haven't more for when on the motorway

Mine is stage at the minute and tbh as it's my 1st powerful rwd car it's plenty quick enough for me at the minute anyway it spins like a bitch in 1st and 2nd sometimes tries in 3rd but when it grips fuck me it goes I love it

One days might go for 380 setup hmm one day

Rsmat

iTrader: (2)

Just buy one of those out dated garret turbos and cap the air injectors and let it run flat out.... They don't go to bad then

400 brake is a fast road car, stick at that is my advice.

I will. Reliable and quick, just how I like it.
