View Full Version : c20let loom and ecu onto c20ne?
ok, ive been thinking this for ages, would a let ecu and loom run a 2.0 8v with a turbo? or is there some massive fundamental thing im missing ( apart from 2 cams lol ) anyone got any idea?

no reason why it shouldnt
just use a let inlet manifold if it fits (no sure if it does tho)
then just use everything else that a let would use really
It will be missing a load of sensors
Arent the ECU's self learning if that makes sence sure somebody mentioned that about an XE an another thread.
If thats the case as long as all the connectors are plugged in i carnt see why not?
But then again i could be talking b*****ks.
Damo.
The lets inlet wouldnt fit the 8v because of the difference in the ports iirc.

such as mate? ive had a bit of let experience but not much.:thumb:

there will be a way of chopping and joing them tho
espcially if you can ally weld
just chop/bend/weld the c20ne flange to the let inlet :thumb:

Hot start valve, tps, knock sensor.
Do 2.0 8v's have crank sensors??

yer they have a crank sensor

it would never fit and the ecu's aren't self learning!

hmm that makes me want to try mate. thing is its all the same motronic. methinks ill have to have a pop at it.....
knock sensor will just bolt to the block, it has a tps, and it dont have a hot start valve but that can be wangled....

Question has to be asked though. Why? lol You wont be gaining any weight advantage like you would with a smallblock. It'd be like fitting a 16SH to a GSi lol

eh? im confused?
eh? im confused?
About what? lol Im saying I can see the point in turboing a smallblock, as they are lighter than big blocks, but why bother turboing an SEH when its no lighter than a LET and a load more hassle, thats all lol
Fair enough if its for the sake of fiddling, but for a performance point of view i cant see the point meself.
dude, my mates corsa 2.0 8v has just ran 316bhp at bogg bros. thats a t3/4 turbo, boosting at 25psi megasquirt, and a sard rising rate fpr. he has machined std ne pistons and the head chambers machined out to give 8.3 to 1 cr. not bad for a £900 build. if i get 200b hp for £200 ill be happy.

And those mods on a LET would be less productive?
i do see your point, but if i wanted to do that with a let id have to pay 1k for a healthy one. then another 900 for bits. the second fastest vaux in the uk is a 2.0 8v turbo astra gte running 480 bhp without gas. its run a 11.2. he built the motor for 3k. if i built a let to that spec id be into 7k or more. the thing is, i havent got let money, i have got my 2.0 8v, so im working with what i have. :)
How exactly is a near 500bhp build that different from let to 8v? ok you've got the base engine, which is 1000 you say for a let and say £600-800 for an NE and then all the turbo bits, to convert it then you have pistons, at the same cost, inlets at the same cost, injectors, FPR's, uprated turbos, rebuild parts... you don't save 4k just having one less cam and 8 less valves.
i paid £30 for my 2.0 8v, there are parts that dont need upgrading on an 8v that do in a let, the inlet for example, and due to the head design it flows better with forced induction. and the last thing is, if i grenade a let i have to pay 1k for the core engine, whereas i can beg, steal and borrow a c20ne.

IIRC when I did a management conversion on an RS Turbo engine, the base map was for a 16V engine. It never ran right and took a lot of work to get the map set up properly.
Cant remember the guys reasoning behind the issues but it might not work!
cool, i may have to look into megasquirt then...
