fcuk 4 cylinders

look how small it is!!!

LS2 , although now redundant by the LS3

[slindborg]

go retro and take the old LS1

That's just gay and you know it! This is just a little something I have laying about.

i hav'nt got a fooking clue what this thread is about,oh hang on its one of those bhp threads isnt it?

[siztenboots]

wish i could find a picture of the underbore 2.0L alloy block to see how strong it is

what does randy think about its potential ( cnrandall )?

some nice manifold and bolt on turbo options


exhaust routing is on the otherside, so much easier to go straight out the back , over the subframe

like this


i think its the right engine for a new lotus turbo esprit model

From reading the artical I'd expect it's essencially the same block as the 2.4L but with thicker and probably better quality liners, as these are the only limit on the 2.2L gen 1 block.

unfortunatly I doubt you'd get enough power out of one and still meet EuroV emissions to warrent sticking it in the new esprit, would be good to see it though in the style of the old esprit GT3 with some post registration Lotus sport upgrades.

The 2.4's definitely supposed to have the stronger bottom end - and I got the impression it had a stronger cylinder liner/supports (than Z22SE) too. The 2.4 is 88mm bore, and the 2.0 (LNF) is 86mm, so it's not like the liners are massively bigger in the 2.4 (although obviously if there was no extra outside radius, 1mm thickness could mean a lot).

Surely the way to go would be to stick that turbo on a 2.4? The longer stroke (and extra volume) should give very good torque, although you wouldn't be able to rev it quite as high I guess.

I've heard quite a bit about people supercharging the 2.4 too... Apart from tweaking the ECU to accept it, the kit for the Z22SE just bolts right on.

no because the stroke is even worse than the 2,2 , something like 101mm stroke with 88mm bore , would prefer it the other way around

Yep, All 2.0 / 2.2 / 2.4 gen 2 bottoms are the same (from a weak L61 to a LNF)
No stronger liners, only the marginaly stronger block from the gen2

This was an LNF btw... http://good-times.we...562048974BhcfDN

(2.0 is not underbore, same bore as our 2.2)

ouch, poor lnf , is there a forum link to the story behind that catastrophy?

The 2.4 is 98mm stroke, the 2.2 is 94.6mm, but the 2.0 is only 86mm.

Each to their own, but personally I'm of the 'no replacement for displacement' mindset - I would have thought that 20% extra volume would make up for the potential bad points of a long stroke. I guess it depends whether you want high-rpm power or low-down torque (or is that overly simplistic? I don't know if it's any different for Turbos).

Yep, All 2.0 / 2.2 / 2.4 gen 2 bottoms are the same (from a weak L61 to a LNF)

It seems the L61 (Z22SE) only got a Gen2 block in 2007 - so all our VX220s will have the Gen1 block with the weaker bottom end.

Impressive failure btw I'd never seen one of them die like that before. Was he running stupidly boosted, or was that a totally stock engine?

heres a pretty picture

i put a direct port n2o kit on...

i worked up to a 200 shot...figured a 300 shot would...

I think that says an awful lot about how insanely strong these engines are. I wouldn't be worrying too much about my cylinder liners tbh

[The Batman]

just make sure you change the internals

[Exmantaa]

Speaking of massive engine failuress... Joe, did I see you lurking on the US forums and asking around for twin-charge options on your orange baby?? You will need some proper tuning options to control all that...

Edited by Exmantaa, 02 November 2009 - 07:32 PM.

[The Batman]

just asking how it would work and indeed would need a very good ECU! to tune it all

after more research trying source this engine on this side of the pond, it turns out the 2.0l LNF is made at two european plants, Södertälje, Sweden and Kaiserlauten, Germany , so still remaining hopeful of getting hold of one. The other option is the manifold and turbo would bolt on to an ecotec head afaik

I can't be certain, but every GenI/GenII ecotec I've seen has exactly the same bolt/inlet pattern. Although There seemed to be minor differences about some oil pressure equalization hole on the inlet side - which Vocky seemed to be able to remedy easily
