As per the title what do people think would be the best engine to turbo to get the most power?

Cams, turbos, inlets etc are all variables which can be changed.

The limiting factor is how much air the head can flow and the size of the engine CC's.

In my shortlist would be.

4 cylinder
Honda 2.2 Vtec
Honda S2000 engine
Mazda / Duratec 2.3
Ford Cosworth YB

5 Cylinder
Audi 2.3 20v turbo
Volvo??

6 Cylinder
Skyline engine?
Supra Engine?
Porsche

Supra and Skyline engines are both capable of around 1400bhp in extreme drag applications on race fuel (ie not meth or alcohol, sure can do more on them).

6cyl BMW M5 engines are capable of well over 1000bhp too no problems when turbod.

4cyl, as well as whats mentioned, you should add the BDTE i guess, and deffo the Lancer Evo engine (4G63), which is capable of handling over 1000bhp.

Nissan SR20s can do 800+

Older BMW 4cyl blocks are crazy strong(remember the F1 turbo cars...)

Actually there tons.

The only think I HATE is when people quote power figures achieved "with reliability" from drag engines, as that is SUCH a misconception when a drag engine in an ENTIRE season will probably run at full power for no more than a total of THREE MINUTES .

I call an engine reliable if it survives a 24 hour endurance race, not three minutes of running .

Stavros

Time to rule cossie engines out then

bud-weis

thing is with your list, you have engines which are N/A alongside engines which have already been turbo'd by the manufacturer, like the YB


are you trying to gauge which 4,5,6 cylinder engines are best in turbo form, or...


..trying to gauge which 4,5,6 cylinder N/A engines would react best to forced induction??

Well the vauxhall ecotec engine is used reliabley (in drag race terms) at 1200bhp


As far as im aware that makes it the best platform for a 4 cylinder engine?

Stavros

Either it seems. Just engines with most potential.

All the engines have been modded to mega power already

salmon

You can get monster power out of audi 5cyl turbos. Sure the dialynx S1 was ~700bhp, although I may be wrong. Also make the best noise of the lot!!

Azrael

S1 doesn't even share engine block with other 5 cylinder Audis...

morto

the best engine is deff all alloy duratec.. massive tunning caperbilities found in new fiesta st

andy

big_wig_074

hayabusa engine
yb
volvo t5
audi 20v 5 pot
audi rs6
porsche 911 turbo
rb26
7mgte(old supra)
2gjzte(new supra)
thats a few good ones i think

Anonymous

Never heard of them running 1200bhp+ like the vauxhall 2 litre ones do in canada and the US

salmon

You can still get big power out of an S2 or UR though!

TM

If you are quoting HP from USA then it is total bullshit the Yanks over rate there HP by 30%.

Stavros

People over here say they over-read, but the black dyno dont lie, and the cars have the times to match the power.
A lot more than we can say for most UK based cars.

I'd still like to see some of these "drag reliable" big power engines do a trackday, let alone a year of those .

evergreen72

i suppose any cast block can handle big power from out set, i think bmw 6 cylinder engines can easy handle 1000 hp, is it not true that the getrag gear box can handle 1000 hp straight away?

sunny

Mike - Everyone knows that drag car engines are not designed to take the continual stress of a trackday hence why the pro drag guys rebuild their engines every dinner time.

Mike Rainbird

iTrader: (3)

Which is my point - you can hardly call an engine that has a full 3 minutes running at full power in one year, "reliable" and "bullet-proof" .

noble use a v6 twin turbo duratec pushing a very easy 425bhp

andy

AustenW

The Audi S1 and S2 turbo engines are basically the same head and block with different inlets, coil packs etc. Both use the same 5 cylinder 20v engine as used by Dialynx to 700bhp plus

They have to be the best sounding engine by far.

As per my previous post I am wondering what engine will give the most potential if turbo'd.

The Honda Integra Type R is supposed to be a monster too although its only a 1.8

I've also heard that there is a 2.4 Honda S2000 engine available in the states which would be crazzy for turboing, thing is they rotate the opposite way round to most other engines.

Stavros

425bhp from a 3litre 24v quad cam twin turbo engine, wow, what a marvel of engineering excellence

Seriously, dont really understand the relevance on this thread...

Mike Rainbird

I love the idea of the S2000, as Hondata do a good ECU and the fact that you can control the VTEC to suit the turbo would be an amazing engine .

and what relavence (SP) does anything you have mentioned about reliablity or avalibilty to complete a years racing or even a track day have to do with the actual title or the questioon asked jsut in case you forgot them


and the title


The Best 4, 5 and 6 Cylinder Engine to Turbo

Mike Rainbird

iTrader: (3)

Because I assumed he wanted an engine to last a bit longer than three minutes . What a silly assumption that was .

Anonymous

7 second quarter FWD they run!


So yeah "obviously" it must be a bullshit figure

sbd16v

but if that was his aim then surly he would ahve put

''whats the best engine to get reliable power from ''

instead of most power would he not ??????

Mike Rainbird

iTrader: (3)

I honestly can't see anyone other than a drag-racer where three minutes of running would be sufficient in a season accepting that criteria . Again an assumption.... . Best in my mind = reliably as well (as in 30k + miles).

Stavros

Exactly, like the big heavy mustangs running mid10's with 550bhp and standard nearly everything.

Yeah, yanks bullshit, cause there times are soooo slow, and we sooo quick

Or maybe its the other way round

sbd16v

but on this thread talking about the most power from one of them engines its very very relevant

when talking most power more than reliablity surly ???

sunny

iTrader: (1)

fast et's prove grip and fast 60 foot times.....terminal is what proves power.

Chip I am not saying that the 7 second cars you talk about aren't mega powered.
I've spoken to loads of American people with mega powered engines, after hearing the spec of their engines and what they quote I was not surprised that yet again I was talking to another bull$hitter. Just my experience thats all.

AustenW

Also heard the Neon engine is supposed to give amazing results even though the car looks pants.

Garage19

I know it has eight pots but i quite fancy a twin turbo chevy LS1

Stavros

And thats why many of them are running 180mph+ terminals and FWD.

Just cause have a lil bit of experience with a bunch of bullshitting kids, dont tar everyone the same.

With my experience most of them seem to underestimate power compared to over here.

Mike Rainbird

iTrader: (3)

Yes, but some of the engines talked about won't even run for longer than 10s at full power at a time, as they have no cooling on the engine as the water ways are filled with resin to give the block the strength required for these power levels. You can't tell me that that bares any relevance in the "real world" . AFAIC you can't compare drag engines with anything other than drag engines. And all the four cylinder "pukka" ones are running 1000-1200bhp fuel dependant . Running them for even one mile solid and there wouldn't be anything left of them .

89xr2

Watching american muscle car's wheelie off the line and then continue to drive most of the 1/4 on their rear bumper would prove the power wouldnt it?

If you're talking about fwd's still then excuse me i'll just myself

Stavros

Exactly what engines out of the ones mentioned fall into that category mike?
