2.0 8v and sell me the 1600 T lol
My friend has a standard 2.0 8v (NE) in his Nova and it goes very very well, he is keeping that in over the 2.0 XE that he has.
ive got an xe but im staying 1600, but i dont want a gazillion bhp all i want is to chuck the motor round bends at speed and not have a heavy front end to worry about

what about for handling wise? the 1.6 would be much lighter, oh aye i almost forgot id be running a f13cr box on the 2.0 8v

thats what i was thinking i live in the contryside and its single track lanes and bendy roads were i live so im worried about the extra weight of the 2.0

i know what the roads down there are like, i work for WM hamilton and sons so id stay 1600 cos the highest gear you'll probably use is 4th unless you get a good straight:thumb:
His Nova handles fairly well for the suspension set up he has on it, no problems with oversteer as of yet. Without this descending into a big block vs small block debate, I've never had any problems with handling in any 2.0 Nova, although I do prefer the small block engines.

I would go for the 1.6T mate.....! Should make good power and be quite light!

2.0 8v and sell me the 1600 T lol
i havn't got the turbo kit as yet just wondering if i should go for the turbo kit or invest in the 2.0
2.0 will cost more to build though
what would fuel consuption be like compared to the 2.0 bearing in mind there will be a f13cr box on the 2.0

I'd go for the 1600 turbo as it can easy be tweeked plus they work out the same bhp as a redtop without the waight.

1st optiojn is all about acceleration, 2nd option would make a better day to day 1/2 economical hot hatch.
1st is tricky & potentailly expensive to build, 2nd is easy & cheap.

Decent thread on it only this week.
Decent thread on it only this week.
there is quite a few of us mumbling about doing this, so is it worth trying a group buy for low comp 1.6 pistons? im in :d

Engines still sat here, yeah. Though a 2.0 8v is tempting.

Dont take this the wrong way, but you wont be building a turbo conversion asking questions like that. Put a 2.0 in it, you have a lot to learn.

Does need a rebore if you do that though, not sure on the rest of the details I've been too busy with other things to carry on reading up on it.

tbf i wouldnt fit a 2.0 unless its at least an seh the otheres are only 115bhp so the weight ofsets the gain for me a mildly tuned 1.6 so head and nice cam and decent manifold and exhaust would give that figure
just read it is an seh i fail lol

I never expected them to drop in, new pistons & old bores doesent make sense.

The thinking was that the Z16 is actually based on the C16/X16 block, not sure how much of that is true but it's either a new design or the blocks just have a different bore in them.

At tyhe end of the day, the baby XE's are getting old & the design is evolving. It seems the 1.8 small block shares some common designs with it, so its a mix of old & new.
They arent on my shopping list yet.

as above it depends what you want id use the 1.6 turbo first off all if you get bored off that go 2ltr!

iv just spoke to a rally mechanic and he said that putting a turbo on a 1.6 will be pants because of the serious turbo lag like the r5 turbos he said just put forged pistons, steel conrods, stage 3 head, high lift camshaft, throttle bodys, have the bottom end set up it would be plenty power with a live remap. he had a 1.6 8v gsi with 180bhp weather he is full of merd, i dont know.
i will now be selling my 2.0 SEH if anyones intrested?

yeah im quite aware of that mate but still learning, trying to get as much info as i can so i can get the jist of it. like i said i know very little about turbos. had a look on ebay for a book on turbos me thinks il have to do some studying lol

Cracking book, very simple to understand, but has everything you need to know plus some, it's much better to really understand whats going on than to "know" a certain thing happens to work when you do x and y imo.

TBH, you arent really going to get the proper info asking on here, opinions & a bit of hearsay yes. Read the book man. :thumb:
