Technical 1242 engine

[HP]

Just wind the allen screw down on the pressure regulator inside the throttle body.

Wouldn't bother doing it unless you're running serious power as you might just end up confuddling the ecu if it can't wind the injector duration back enough for idle speed..

Hmmm maybe one for the future there then....

Nice to know someone else is thinking on the same wavelength

but how would u kno how much pressure u are running.

and would u need to mess with the pressure if say u put a tuned 1242 in that had about 85bhp?

just tryin to plan for the future haha

Erm...dunno, personally Id wanna hook it up to some diagnostic software (ECU spits out an unbelieveable amount of data) and twiddle stuff, monitor everything and generally have a play until it all works together....

for sure man i got plans for engine mods, but am undecided weather the do a 1242 or just stick with the 1108...

but when i do get to engine mods i am goin to b wantin it all set up on a rolling road day to get the most out of it!!! has to b done!

I have now got enought cash together for the 1242 engine swap for the cinq, I now need to know if any body can recommend a garage in west/south yorkshire that could do the swap for me. I also want the head porting and cam replacing and t/b from trickler. I would like to find somewhere that would do it as a job lot if you know what I mean

just to get back on topic a bit (poor lads turned it into a techi thread!! lol)

polis the head your self mate!!!! honestly its not that hard to do and if your worried get one off a scrappy all they do is sit with a dremmel for a day removing the carbon and any rough edges, think last months practical performance had a big DIY bit on head and port polishing

as for a garage if your able id recomend Paxtons in wrexham its a bit of a treck for you but you WONT be dissapointed they love cars and share your passion dont look at it from a "why do you want to do that" more a "that will be fun!" point of view!!

 

[crazy_cinq!]

get it chipped as well, mckrich's chip is well good apperently, and keeps the imobilser for £50.

First of all.. there is one going on eBay at the moment but the seller states if you use it regularly.. leave it in to work full time, that you need to replace the immobiliser !! ??

 

[arc]

prolly means for secruity reasons, you may want to invest in an aftermarket imobiliser

Hi

Well said!

I did my cylinder head and inlet manifold from the 1242 engine myself and I have 115 Nm (102 Nm) and about 75 Hp (60 Hp) with a 268 cam from Colombo & Bariani.

It took me a weekend to polish the inside of the cylinder head and inlet manifold. Remember to match the inlet manifold to the ports in the cylinder head - you can use the gasket to calculate where to remove the material inside the inlet manifold and cylinder head to do the match

Good luck!

Tricker...

PS. Regarding my last quote: my calculate with the injector is with 1.5 bar fuel pressure not 2.5 - my mistake
