im am driving a 1.2i nova,
i have a 1.4SR engine for it but i have been offered a 1.6 cav car for nothing, would that engine be better for the nova? it has 150,000 miles on it but the SR hav 120,000, ????????
i have twin 40's also and i will be puttin a bit into the engine aswell,
any ideas would be appriciated
What year is the Cav that the 1.6 is coming out of? I think the earlier Cavs had "Big block" 1.6 engines in them so the extra weight would cancel out any power gains and the handling would suffer aswell.
High mileage doesn't seem to be a problem for most Vauxhall/Opel engines. I guess the Cav's engine might have been driven easier (i.e. not thrashed) due to the fact that it hasn't come from a car badged SR.
If it's a 1990 it should be small block. You should be able to tell from the rocker cover. The big blocks I've seen have a breather pipe coming out of a square shaped box on top of the rocker cover whereas small blocks have completely flat covers. Put the carbs on the 1.6 if it's small block. After the injection system/ECU, I think the cam is the only thing different from the 100bhp Nova GSi engines (could be wrong though).
What kind of Nova am I building?: I'm working on a bare '92 ex-1.5 diesel shell. It's only done 49k miles and has been in a shed for the last 5 years. It's in the middle of being stitch welded, fitted with the Harry Hockley strengthening plates and mounting plates for a 6 point roll cage. There's a wide arch kit ready to go on it with modified (by me) GSi style bumpers. I'm saving towards getting the shell rolling at the mo. I'm hoping to have the wide track kit from TAS in a few weeks, along with quick rack steering and an AVO coilover suspension set up. Just have to wait for a good moment in the exchange rate department. (Damn Euro!!).
Won't make Clonakilty on Sunday. Gotta go to work. DOH!
Yup, insurance here is a joke. You could always use the 1.4 for now and take your time and do a complete rebuild on the 1.6 (Blydenstein head, cam kit etc) and use it when the insurance cost drops a bit (probably be a cold day in hell that day!).
Thanks for the offer on the rear discs. I'm undecided on that idea yet. I've heard a few horror stories of the rear end locking up too easily and there won't be much weight in the back as it is. I guess with a lightweight 1.2 under the bonnet, you only have to look at the pedal to stop yours!
Are you going for 1.4 up front, 1.3 in the middle with a 1.6 in the back kinda thing?? hehe.
1300 engines seem to be fairly easy to find (even in Co. Kerry). Try the scrapyards for 1.3 Kadetts/Astra mk2's. These engines produced more power than the Nova 1.3's. (75bhp as against 70). If you get really stuck, I've got a stripped 1.3 engine. It came from an '89 Kadett with 71k on the clock. The only wear I could see was on the cam - maybe due to spending a lot of time idling in traffic??
Have you fitted antiroll bars? I had SR ones on my 1.0 and they made a massive difference.
Kieran:- i have been looking but i do want 1 that has low milage...like the 1 you have?????
what is missing from the engine? coz i would be interesting in buying it?
i have got the roll bars in alright made a good difference to her.
Mick:- well hinchy says a few hundred yoyo's and i can take the car away, it has a sunroof and recaro interior, and that all important engine, but thats a bit much for what i want it for(1300 engine) + i did'nt hear it run, i might go up next week with a few pound and take it for a run.
hinchy took me for a spin in the astra gte, its some car, he is a nutter, he proved to me that they were a twitchy car on the bends alright. what a laugh.
oh ya ill put the word out about the car 2.
I guess that puts at least three of us in the fight against the saturation of Civics we seem to have over here then!
I've taken a few photos of what has been done so far, not developed yet though. I could really do with getting my hands on a digi camera beacause I want to try and get each and every stage of the rebuild on film. I can mail a few through to you when they do finally get developed if you want.
I think all you'd need to put my 1.3 back together would be typical rebuild stuff like rod bolts, bearings, gaskets, headbolts etc. It was basically stripped down with the intention of rebuilding it with a few tuning bits added on to squeeze out more power. After adding everything up, I decided it would make more sense to try and get a 2.0 and start out with 150/156bhp and work my way up from there.
