my car was original a 1.2 8valve Vegas. then it died..........

so.

my mate built me a new one.

its now a 1.4Sri block with a Astra 1.6Gsi head, so you would think it would be fast...wrong

i still have the original 1.2 gearing at moment but it just don\'t feel like it should. sluggish allot. any1 know what a could do? with the amount of things i have done to it you would expect it to be better.

the same as the sri propbably

80 at best

if it\'s a 1.4 16v SRi, isn\'t that 90bhp alone anyway joff? unless sparkles engine is 8v i would of thought it would be more than 80? But i don\'t know poo about engines anyway! ????

I was thinking Astra 1.6 GSi (ahem) more likely to be a Nova GSi, C16NE.

who knows!! astra or nova, not sure but it still dont feel like it should.

if it has a GSI 1.6 head it will be slower because the compression is lower y u using a 1.6 head?!?!?

ps now u lowered the compression get a 1.6 gsi exhaust manifold and bolt a r5 GT turbo to it get power flow to make you the downpipe, get a frontera intercooler, all hoses and boost pipes made up (cheaper than u think!), get an oil feed welded to your sump, put a power boost valve on your fuel return, get ur ecu re-mappped and rolling roaded... oh and a 2.0 fuel pump... and then you will have about 160bhp - 180bhp (may wanna get turbo cams)

or just bin the engine and get a C20LET!

spoke to my m8\'s dad(who built me the engine) and he said it IS a 1.6 Astra head. the compression wont be lower. i tend to trust the guy because he has been building these things for over 35 years as well as racing them in stock cars.

i am hopefully getting my new manifold and twin down pipe( think its Fae a nova GTE) tomorrow morning.

if everything goes to plan it should be something like this......custom built block, Astra manifold with twin down pipe made to fit, de-cat pipe through to tenzo 6\"back box.

should change the compression slightly but hopefully for the better.

get it on the rolers m8

Is it still ont he 1.2 inlet?

wouldnt have a clue.. where would i look to find that out?

i know nothing about these types o things..

all i know how to do is strip cars down, replace all windows and tint them and put em back together..
