ecotech?

[Philsutton]

Right since ive buggered up my redtop an gearbox, ive been looking for a replacement engine and its becoming very hard to find a decent cheap xe. I have seen lots of ecotech 2lt 16v with very little milage very cheap. I no they only make about 130ish standard but i though that this power loss was in the injection system as it differs from that of the xe? If i was to swap my QED cams over in the ecotech an put it onto twin 45s/48s would i be looking the same sort of power for the xe. Or does it not work like that. I dont really know much about these engines so any help would be great.

Dont think the cams and that are compatible, there not as bad as everyone makes out really, can get big power if you are prepared to work at it.

There are plenty of XE's about, what do you consider cheap?

[Philsutton]

i consider about 200 cheap but the engines that go for that price have 160000 miles like the one i have now, i dont have the time to rebuild it.

[Ben]

Yeah well for that kind of money thats all you will get, got one with 76k miles on but wont sell it that cheap.

[Stuart]

you also have some EGR rubbish to get rid of etc, but with carbs that will go :)

also the eco tec head is less likely to go porus.


chap on mig flogging a F20 for ?50 and another bloke selling 4* 20xe + F20 gbox's

[Ben]

F20 for ?50 robbing sods!

[burgo]

i thought the eco-techs heads were more restrictive as well???

and you can get 2l 16v eco's with 60000 on for ?50 down my local scrappy

am i right in thinking the engines in the daewoo nexia's are exactly the same as the eco-techs, as they look pretty identical

i thought the nexia's only came with a 1.5 or somethin like that?

[burgo]

nope there was one with a 1.6 which looked exactly the same as a gsi and a 2l 16v which looked the same as the vauxhall ones

just done a search for daewoo nexia's and can only find 1.5's

no 1.6's or 2.0's

heres some pics for you to make ya own mind up

them two pics of your, one must be the 1.5 8v and the other 1.5 16v :idea:

i remeber tv featured a Nexia, which had full astra gte running gear and interior/dash etc so you could be right about that

Ecotec are'nt bad. My dads vectra sri140 is quite fast, altough the torque of it is really amazing, in 3rd gear none of the power drops at all, its abit like a fast turbo diesel u know like the power comes in really early in the rev range and has a strong pull in your chest and head (down force) its like that but the whole way thru out the revs. If your going for one the sri is slightly better than standard as it makes about 6-7 bhp more. One thing to make sure of is to replace the camshaft sensor and espically the crankshaft sensor before fitting it to your nova because the crankshaft sensor is a bas*ard to replace because you have to take the power steering pump off and a few other things, don't trust anyone if they tell you the engine was running fine because they need replacing about every year to year and a half. good luck

[rednova]

that pic of the nexia 16v engine is a 1.5, they made both 1.5 8 and 16v, your right they do look similar tho, else youd get more people puttin the nexia engines in novas if were 2l (low milaege etc.)

what did you do in the end phil?

i stopped at the bp services further up the m1 and didn't see you come past

[Snowface]

the engine mounts are all different in a nexia to the astra/other Vauxhalls.

Its a bit of a task to put an 20XE in there aparently.

[Philsutton]

well it kept popping out of gear an locking the gear box up which was really strange. Then when i did get going there was a nasty grinding noise.

i remeber tv featured a Nexia, which had full astra gte running gear and interior/dash etc so you could be right about that

that car was from Grimsby i think. I was workin wit a guy over summer and it was his best mate who owned it. He got an old astra mk2 GTE 16v and basically transplanted everything over. The nexia is basically a newer more rounded mk2 astra. Could be because Daewoo was mostly owned by GM.
Dont think he has the car now tho

he sold it before the feature was done, i think - without looking at it

The X20XEV makes 134 as std I believe. This is due to many reasons:
Cast upper manifold this is a cost saving compared to the s/s tubular effort the redtop has and reduces potential power
Inlet manifold, the port shape is different and ecotecs lack the SFi box hence lossing midrange torque
Cam profiles, are much milder than the redtops cams to reduce emission
Head design, the head is a lot more compact on the ecotec heads, causing the exhaust vlave to sit vertically which makes the head restrictive.

If the head and pistons are ok then a re-ring, new shells and lapping the valves back in would get the redtop back up to speed, the power talks for itself. 150BHP 149Lbs, the ecotec can't get that torque or power for the same price you could rebuilt a redtop up to speed with.

[m.d.]

interesting stuff there mate, you have just made up my mind to get an ecotec later as i could do it as a project and fit my 45s to it to reduce restrictions, i can port and polish heads so the head restrictions wont be a problem, and the exhaust really is no problem at all,

hmmmmm, maybe i will :wink:
