how much would it cost to build a 500bhp reliable cosworth engine (estimate) from people who have done this..

not interested in top speed but a lot of torque and no turbo lag so was wondering what turbo would be best and also what compression would i want the engine to be?

any help would be much appreciated!

 

self build? or for an engine builder to do it? - if its the latter just phone a decent engine tuner/ builder up and talk through the spec you want and want you want from the engine - bit hard to put a price on it

 

thanks for the reply.. would be a self build possibly.. this is why i was wondering costs.. am interested in hearing from anyone that has done this. thanks

 

it all depends on what you can do yourself mine is costing probably around Ł2-3k, but ive done pretty much all of the work myself, including the machining

 

matters on the condition of the engine your rebuilding.

and what parts your going to change.

 

7.2-1 comp ratio, std crank and rods, flowed head, GT30 preferably external gated. 4 big injectors using level 8. Swedish or small escos inlet and get it properly assembled with good gaskets and ancillaries and you get a monsterous 550bhp reliable ANIMAL of an engine...

Martin at Reyland. Job done.

 

I thought 9.6cr was the latest trend

 

ideal, was thinking of a similar spec, did'nt think it would make 550 so ideal

think i might shit a brick at getting it done by martin though money wise because he is so good, but could be wrong.....

 

what about transmission though,can yours handle it.

 

do it once... do it right! Normally cheaper in long run as well

mine has been amazing. If you are local to Essex you can have a demo. You REALLY don't need any more... I had over 600bhp on a GT35... but this engine spec is FAR FAR better and faster 99% of the time

 

Exactly - if you can't afford to to build a 500 horses engine properly then you can't afford it at all. 500 brake isn't done on a budget.

 

theres no tight budget, just dont want it to spiral out of control, i am also just about to get quaife dogbox which has been in a cossie running about 580..so that bit should be sorted...

 

Cool !!

 

pm sent..

 

fooking awesome engine,martoon built mine,karl at nms mapped it.

 

i remember reading an advert a couple of years ago that quoted Ł12000 as a starting price depending on the condition of your existing engine for a complete 600bhp rebuild. no idea of how reputable the garage was.is that about right these days or has it risen drastically ?

 

Porkie has given good advice but doen bother with the old
cossie ecu they are ok but technology has moved on too
much and their capabilities arent that great anymore
as to the inlet the escos small turbo inlet is going to give
less lag as the swedish inlket takes time to fill up due to size
but you could always stroke it to say 2.2 like rainbird has as
this give the best comprimise between response and being
able to rev other than that speak to martoon as he is a
reputable engine builder and seriously sonsider the skyline
'box conversion as it will give you twin syncros and is strong
too!

 

nothing wrong with L8 at all!!

 

..i have level 8 with anti lag/launch control,with optional closed loop and coilpack operation..yes a really outdated incapable ecu

 

yardy2186 Why not use the L8, Loads do, and loads love it.

 

Care to elaborate??

 

Amen brother!

 

We'll said that man

 

How reliable would this really be? The only reason I ask is during a telephone conversation with Mike R the other week I was told that a standard cossie block wasn't really good for much more than 520 (he said 500 originally until I pointed out his sierra was 515 )...

 

I reckon reliability is not an issue.

 

The secondary question should be

"How fast can I afford to go?"



As with most modifications at this level..... the engine is only part of the equation. You could end up doubling or even trippling the price dependant on your intended use and what needs to be done to the rest of the car to cope with this kind of power level.

Nothing comes cheap..... you have been warned!

Don't skimp and do it right. It could all end in tears otherwise.

 

Sorry mate... I totally disagree with the ECU. Name me ONE thing you want that the Level 8 can't do!?!??!?

Closed loop, Launch control etc etc and they just WORK sooo well with Cossies as the transient fueling is funnily enough factory!

Disagree with the 2.2 bollocks as well.. over complicated and expensive! My engine is NUTS... you would never need more on the road.

Its been BOMBPROOF as well! feels like it could on forever!!!!

 

Ok then... to play devils advocate again. I have been told by a very well known tuner that you could get away with running a higher comp if you had Pectel T6 over say L8. I forget the reason; I think because it computes faster I guess so you have a more accurate map. This is a TOTAL guess though as I can't really remember

?

 

Data log, wideband closed loop

More if you want .... (No diss to L8 though, as I agree with what you say)


Total bollox

 

Engine Advantages?

TOTAL bollox

 

has anyone ever mapped one engine on a dyno with two different ecu,s to see if anymore power can be made over a l8

 

NOT engine advantages! Arguably MUCH more reputable than them!

Like I said. dont pay any attention to the reason as thats my guess to it BUT I was told about the CR and ECU link!!!!!

 

No point quoting it then if you can't remember the details

 

My guess is you had some an glu in your ears at the time and misheard!

 

Given to me that sounds like a fairly basic spec for the power produced, does this mean the cost isn't completly silly? - I'd imagine the head work would be a grand, and a suitable turbo / to be roughly the same, but assuming you've got a decent breather / sump setup the above otherwise sounds like a standard, low comp bottom end rebuild? (sure i've probably got the wrong end of the stick - just trying to work out numbers in my head.... )

 

That's what I was thinking. Poss a rebore and hone and a new crank but still not silly expensive. I thought 500 bhp would weigh in easily Ł6k+.

Can anyone give a rough cost? If it helps my engine is a strong stage 3 rebuilt 12k ago. Although it is a 205 block, so maybe a few more quid for a 200 block.

 

This is a WERY cool setup, even tho i would prefer the swedish inlet over the escos one, think it´s WAY better, but maybe that is an matter of taste.
On my gt-35 engine it comes on boost @ 2700rpm and makes full boost @ 3800 rpm, so real pleased.
Ecu wise, well have seen some sweedish cars on std p8 with over 500bhp, so would just use what u have now

 

Get a GT35 done correctly & it will kill a GT30 99% of the time. FACT.

 

I will dare to say the same, in my experience

 

not sure that was what porkie as trying to say rod , he said with the gt30 its fatster , probabbly as a overall driving package ,

more useable = faster round track ect .
