making hp with an N/A 6cyl?

Also ease of compatibility with the Throttle Position Sensor.

I agree for the street a mild cam, vk efi , big injectors and a big throttle body with good management would be a nice package, easily better than those p.o.s buick v6s, rough old hunks o'shite that they are. Also my prefferred option would be six throttles with a well designed airbox and cold air fed, and good heatshielding from those big thermowrapped extractors you'll want to be fitting....note that heat soak is an important factor in non-crossflow head engines as the ports and manifolds are always so close. plus on efi exhaust temps will likely be hotter since it will be running lean-ish.Don't skimp on a high quality timing drive-maybe even a gear drive. Go a high volume ouil pump. Roller rockers should be handy if you run more lift, and maybe aftermarket, lighter, stronger pushrods should be considered.MOre compression is a given here for more power.
You could consider a stroker kit or a big bore, but keep in mind that engine harmonics are very complex and it would be hard to build something that doesn't vibrate and shit engine mounts and stuff like that. That said a nice light flywheel would make the engine rev a bit sweeter, as would a nice light set of rods and pistons.

Point to note: all 202s are gear driven. However an alloy gear instead of a fibre one would be a good upgrade.

just buy a Ford six they go harder

i havnt had a ford six beat mine yet

stroker 202??????????????????????

Does anyone known if there are stroker kits for 202's, I know that their are stroker kits for 186's.
Hey does any one do you have any ideas on how to setup six throttles on an 202???????????????/

[Feenix]

You can get triple 2bbl side draught webers for a 202. You can then also use the weber style EFI kits if you really want.

I think this kind of setup would be difficult because there is little to no plenum area so the computer can't really sense airflow too well. Of course you can put an airflow sensor in but then it would either have to be replicated 6 times (and you'd have to find an ECU that supported that) or averaged over the 6 cylinders.

Thats my thoughts anyway.

nos288: so how much do you want to spend then?

if your going to waste money on a stroker kit for the 202 (out to 208, wow) then change the engine to somthing else.. what car have you got?

Feenix, the kalmaker tune for delco can/will work for 6 throttles as it can use TPS based mapping at idle up to 1500rpm or whatever you set it to then it swiches back to the map sensor.

pushrod, have you driven a car with the V6? In stock form, they truly suck. Ive been passenger in a modified manual VS that was actually kind of impressive, but going to all that trouble just to put a crappy v6 in... bah.

[208_Fireball]

202 -> 208 is just by boring to .060 oversize pistons. Nothing to do with stroke.

Apparently there is one QLD company making cranks for stroker 202s, but I have yet to find more information about the company. A few Hypo shops can make custom stroker cranks, but $$$ are involved. With a stroker cranked 202, 220-230ci should be possible.

The zoom buildup with delco efi was hardly that mild a cam - 300ish degrees of advertised duration's getting up there...

Street machine mentioned that the car was loping to much to use MAP or IAC, so their cam wasn't the world's mildest either.

You can stroke a 202 to 250ci using a modified pre-crossflow ford crank.

A 202 is just a stroked 186.

'nix

[208_Fireball]

Not true. The 202 and 173 motors have larger main journals than the 186,179 etc, which disallows the ford crank to be used within the 202s.

Also, the largest i have seen the 186 stroked (and bored) to is 236ci. (With the stroker conversion it is the ford 221 crank -modified of course- with ford 250 pistons)

Cheers,

Dave

[Feenix]

In terms of bore x stroke, the 202 is a stroked 186. You can always grind the crank journals smaller to fit a 202 crank in a 186.

'nix

[208_Fireball]

But, you can't enlarge the ford 221 crank's journals to fit in the 202 (easily anyway.)

Cheers,

Dave

[edit p.s. does anyone know any brissie places that do custom cranks?]

Slip: I only comment on topics which I know facts about, and in answer to your question, yes.. I have driven a Vn V6, I have also converted a mates VH to a V6 (the only thing I didn't do was balance the tailshaft) which I have obviously ridden in/driven many times.

And if you thing the vn v6 is a crappy engine, have YOU ever ridden in a 202 powered car before? in stock form they, truly suck.

NOS388: there is really no point in anyone offering any advice until we know what you want to spend, and what you want to achieve, also what car.

edit: forgot to mention that the VH V6 is a weapon which handles like a go kart (VN sway bars & lowered) and punishes many unsuspecting red light racers.. its about as quick as a stock WRX (no shit) and the engine is a series 1 with stock vn exhaust & not even a cold air feed. so get a VS engine ~ 147kw instead of the ~ 126 kw from the VN - VP engine and you would have a very quick sleeper which uses **** all fuel
