making hp with an N/A 6cyl?

[Feenix]

Typical guideline is up to 50% of the engines factory horsepower can be added.

Eg 200hp stock can take 100hp nos

There is really no hard and fast rule when it comes to modded engines and nitrous use, ie, if you have a bulletproof bottom end, you could see 500hp ... Though when talking about stock or mildly modified engines, what Feenix said is correct, work on the 50% rule.

That red cortina with the six in it (EFI and Nitrous) would have to be making over 500hp to run the high nines that it does!
(it also frequents the off street meets at AIR)

about the falcon 34adm carby... they go onto the 202 (black) easly no mods? where abouts could i pick one of these up, im in canberra and how much are they worth?

I've played the old-school engine game, and I've formed the conclusion that it is one of the easiest ways to spend a lot of money on making your car a complete pain to drive....

What I want is a nice modern 4 valve per cylinder DOHC motor with individual throttle body fuel injection and a 9000rpm capable valvetrain/bottom end... and I can probably have it for less money than my old 'old-school' motor would cost to make 25% less power... sad really... or alternatively, I go the forced induction route... oh, did I mention what I buying with my tax cheque?

[Datto-Zed]

Hotgemini: So what engine are you using? 20V 4AGE springs to mind...

[hotgemini]

Close but no nicotene delivery device, CA18DET... expect pictures as soon as my tax return cheque A) arrives and B) clears.

there not built for racin from factory
But Ive seen a genuin 220 Kw naturally aspirated injected 202 ( the 6 throttle bodies where a bitch to tune though and it takes alot a high qual parts

sounded absolutely awsome

it required quite alot a head work balancing, a rather aggressive cam and valve gear and other stuff to ( dont wanto go into it got things to do )
revved to 8500 Rpm and was just drivable

I think this is about as far as U can get them B4 there shit to drive on the road, very loud to ( but it sounded awesome enough not to care )

[hotgemini]

Linx, while your post (I believe) was in defence of 'old school' motors... it basically summed up my problem with them, you get to spend a whole bunch of $$$ rectifying design flaws and end up with an inferior product.

Imagine if that same money had been spent on a naturally aspirated 2JZ? Individual throttle bodies, porting, cams, custom exhaust, engine management... no reason not to expect 350hp at 8500rpm, day in, day out... totally streetable.

??????????

Hey Linx can you tell me more about this 220kw engine?
Especialy about the induction side of it. :D :p

[NOS388]

:D :p Pretty please.

[NOS388]

Where they triple dual throat side draft webbers(modded 4 EFI), or actual throttle bodies?

buick v6 quality

I used to be a bit against a Buick v6 and opted for a Nissan powered VL as the v6 has the stigma attached to it for being a rough jurrasic engine.
From my experience,whoever says these engines are crap doesn't know what they are talking about,we have 2 Commodore v6's,if well cared for the VN is not too bad but still not a silky smooth engine,we also have a VX and it is smooth as,cannot hear or feel it run so anyone who says they are crap are misinformed.
Any Buick V6 can be made to run more like this with a proper crankshaft balance (was a problem in the VS Commodores) and a good engine management reprogram to smooth the idle out.
These engines can turn a Commodore into a lethal weapon once turboed,they achieve 11 second quarters in the states in the Buick Regals & Grand nationals.

[Feenix]

They don't run the same blocks or cranks in those fast turbo cars. They use the 4.3 litre variant and an odd fire crank

[RB30DEVL]

Re: turbo Buick

They have bigger capacity enignes than the 3.8 yes but go to the Buick website http://www.gnttype.org/techarea/recipes/9secrec.html ,it shows a 231 cubic inch V6 (3.8 litre) bored to 234 c.i which puts out a "9 second quarter time".

If you're not a diehard GMH fan, I reckon the cheapest way to get 12s out of an NA I6 would probably be to go a Hemi 265 (with a bit of work) in a Centura.
