Red top engine

[nova addict]

am looking to put a 2.0L redtop engine in a nova or a 2.0xe am a fairly experienced mechanic am just wondering how hard it is 2 do cheers

Please use the search function, there are countless posts on this ;)

Guide in the Articles section.

Also, theyre both the same engine :)

Missed that bit lol

[nova addict]

cheers anyway but just to say there not the same the red top has a diff head on it 2 the xe :)

The 2.0xe or c20xe engine are all commonly known as the "red top". The only difference in heads on the aforementioned engine is that some of them have an expensive coscast stamp on them.

Learn somthing new everyday!lol

FFS Lee, EVERYONE knows there were two 'redtops'!

Although, I suspect that one has a RED top and one doesnt.

[nova addict]

well if the heads diff it will change the compression ratios in tht so there completly diff engines the 2.0xe runs abouts 150bhp standard were the red top runs around about 200bhp standard

Thanks for the info :thumb:

I always thought the XE had 150bhp, and the LET had 200bhp.

Ive been told.

[Leeboo]

C20XE 150bhp standard

C20LET 204 bhp standard

LET is a turbo, lower compression!

[Leeboo]

Beat me to it Lee lol

[Jack]

I have a red top, but it doesn't make my car any faster when I wear it :(

Compression ratio adds 50bhp? :wtf:

Incidentally, I know of standard "Redtops" which run 200bhp.

a extra 50 bhp just because of head work wow :D i need to get one of them lol!

any1 else confused or just me

Not just you, clearly our friend 'Nova Addict' is massively confused! :roll::roll:

LMFAO the c20xe is 150bhp and the LET 204bhp, the heads are actually the same on both bar the valve springs and seats and cams. The difference in compression ratio is in the pistons not the head.

An like already said the C20LET is a turbo an hence why it makes 50bhp more, thats the only reason.

the compression ratio is due to how close the head is to the pistons there fore u get a head skimed more it will created a bigger compression ratio the redtop heads r also made by cozworth so there for have diff engine numbers so they are totaly diff engines cheers anyway

Dude, i'll get you a shovel to dig yourself a bigger hole with!

The heads are not made by cosworth at all iirc, "coscast" refers to the casting method. A different engine number does not denote a different engine, C20xe or 20xe is not the engine number, it's the code. :thumb: . Seriously, listen to some of people on here, they know what they're on about!

[edens-xe]

nova addict!!!
cosworth only designed the 'redtop' engine and it makes no differance at all, the coscast head was made to overcome the pourous head history amoung with other changes of which im unsure of! c20xe or 20xe are still the exact same engine:thumb:

and trying to prove everyone wrong in this thread bearing in mind some people on here actually go to sleep with bits of the engine under there pillow at night, have alot more experiance and knowledge about the engine than one persons 'knowledge'!!!!:D

[ELLIS GSI]

lol at this thread

[Adam]

And a coscast head is no better than the gm one lol

[Adam*D]

Quality thread, this should be made a sticky so when we're having a bit of trouble with our motors we can laugh at this thread and cheer our selves up a bitlol lol lol

[Lee]

lol

Man I feel Stoopid.

Edens, I had to stop sleeping with engine bits, I was waking up with bits of crankcase in my grundies.

lol lol lol Uncomfortable!... ?

[BIGS]

lollollol ive just read this tread and cant stop laughing. im sure nova addict must be right it sounds like he knows his stuff :D

[KITT1972]

lol lol lol I agree with you all muppet, having rebuilt a 20xe not c20xe there are only a few things diff with engines like timing pullies and the flywheel, lamba sensor the 20xe is claimed to have 6bhp more then the c20xe your right when you say its just a code number the c in c20xe stands for cat thats all nothing else.

200bhp from a standard 20xe or c20xe I DONT THINK So lol lol

[Nova_Tek]

Im pretty sure that if the 20XE or C20XE (forget which one :confused: ) could produe 200BHP stock then we'd all be XE'ing our Nova's then turbo'ing that muhahahahaha imagine that :D

Sorry Nova Addict I have to agree with the masses here mate.

[Jack]

200bhp from a standard 20xe or c20xe I DONT THINK So lol lol
200bhp from a standard C/20XE, no

200bhp from a standard redtop, yes :D

Always thought the Coscast head came first then they binned it for cost reasons, the GM head was then produced by another supplier, Karl Schmidt springs to mind:roll:
I think the Coscast was then used again on the LET wasnt it?

(Awaiting being shot down in flames and having the p!ss takenlol)

+ points for actually knowing how compression works, however they are the same engine bar a few sensor changes and the lack of dizzy on one and a few other very minor differences.

Unlucky for you though there is some serious negative Rep coming your way for:

1) Not having a ****ing clue what your on about

2) Using letters like "r" and "u" in replace of words in order to save your one finger you have left after your other nine are lodge deep in your colon.

[paulnova]

PMSL at this thread lol

[Lee]

the c in c20xe stands for cat thats all nothing else.



FYI the C stands for the particular emissions reg the engine was conforming to.

C = Euro 1 standards (also known as EC 93): Directives 91/441/EEC ;)

lmfao lol made my day anyway :thumb:

fpmsl i knew there would be some comments about the bed buisines!! now i know who to watch out for when i come to pvs!!!lol
