1.3sr 130BHP HOW????

[NuttyNovaBreg]

How do i get my sr to spit out 130bhp!
So far i have:

Janspeed full system
Fast Road Cams
Port Polished Head

and am in the process of gettin a weber 32' 34 ' slaped on with k&N?

I WANT TO AVOID TWIN 40S? So how do i do it?

[Slatter]

LOL

stick a max power sticker on windscreen .... guarenteed 130bhp then !

:roll: :roll: :roll: :roll: :lol: :lol: :lol: :lol:

[Stuart]

you need a turbo, nos, lots of valves or a miricle

[Dan]

I reckon it would be like weeing in the wind, you really really dont wanna get your legs wet but no matter how hard you try it aint gonna happen

[Aragorn]

if u went for summat similar to dans spec on a 1300 or 1400 you could prolly just about reach 130

ive heard of folk with SRi's hitting 120 on the injection system so it shouldnt be that hard if your willing to spend the cash

summat like sri head, twin 40's, raised compression, B++ headpack, rally slag cam etc etc u might just get there

[brian]

i know of a few 1300 rally cars runin that kind of power but it takes a lot of work and an awfull lot of money. its not worth it. in rallying its worth it because its good power in the under 1400 class.

[brian]

why not go for a bigger engine?
It cant be an insurance thing anyway. because declaring whats done to make a 1300 up to 130bhp to an insurance company would surely be the same as a quote for a bigger engine???
and if you weren't gonna declare the mods then you might as well have an undeclared bigger engine!

[dikharvey]

A 2.0 engine from a cav SRi. 130bhp as standard,

[brian]

and as rare as hen teeth. if yer on about a cav130!!
lovely engine though

not necessarily

liverpool victoria WELCOME any engine modifications BUT dont wanna know really if you change the CC

you guys are very lucky that insurance companies actually understand things like that. in Ireland they would not know where to start with a "mod'd engine"

[burgo]

i spoke to this bloke once who managed to get 130 out of a 1.3 but he sed u have to spend thousands and thousands on engine tunin so its really not worth it

[beghy]

its is poss to get 130Bhp out of 1300 but it involves fuck load of work, i think for u have to bulllet proof your bottom end or else it wil let loose due to the amount of turque the bastard would produce. to achive 130bhp it will probably make peak power around 7500 or 8000 rpm, so its got advisible for it wont go no where untill it reached 3 - 4k rpm.

[Fester]

change the engine for the suzuki swift 1300 16v engine - easy 130bhp then :lol: (yes it goes in on a vauxhall gearbox, there was an old thread somewhere)

[MC]

130bhp will be easily achieved, but you will have to use twin 40's.

Look to pay around ?300 for your bottom end, ?460 for a decent head, ?200 for a proper cam, ?200 for a competition exhaust and manifold and then add on the price of Twin 40's with some large chokes.

That is realistic, you will have a peaky engine, but you should still have enough low down torque to get away quick. As long as your engine is sound it won't fall apart.

Why don't you want 40's? They are easy to use, reliable, start first time and sound great, not to mention the power.

*cough* fuel consumption *cough*

:lol:

[Jules]

I think that fuel consumption is gonna be a problem if you've got 130BHP from a 1.3 wether on 40's or not, not to mention the initial cost of getting it up there in the first place (Don't forget another ?50 for AA cover or something cos it'll probably be very unreliable)

Don't really see how you can do it without using twin 40's but if you do mange it then I'm sure we'd love to see it (And the rolling road prints out as well!!)
:twisted:

[Ben (lurk75)]

180bhp has been acheived out a 1.4 (16v i know but still)

[Slatter]

ive had a shit load of workl done to a 1.3

It needs settin up but we recons its gonna produce around 110bhp

Id persoanlly be surprised if it got that... but it has all that mc says !!

[beghy]

MC is right.... last year at the PV Show (if any of u remember) there was a nova sport on the strip with a mk2 astra 2.0 16v turbo, the nova ate the turbo on the 0-60 n 1/4. if im right this same nova sport was reviewed on one of the early last year Total Vauxhall Mag, well if i remember that little pocket rocket made 130Bhp but it did have ?3000 worth of work done to it.

this thing had the ballocks done to it:-
Forged Piston (High Compression, 10.5)
Forged Con-Rods
and all the other ballocks

[rgv_stu]

its a 1400 and it now makes approx 150bhp on throttle bodies

[Ben (lurk75)]

Just take it to interpro they will get it upto 130BHP if its a standard engine with a K&N.

I sense a little bit of sarcasam there Ben! :lol:

[MC]

My 1400 had 130bhp still using the 1.4 head and 30mm chokes. Go up to 32mm and use the better 1.2 head and who knows?

The 1300 already has a decent head, so fitting 40's with 32mm chokes should see a RELIABLE 130bhp.

[Aamir]

NOS !!!

25, 50 & 100bhp kits

Speak to Chip from MigWeb

[wrigleys]

my new 2.0litre 8v is 115bhp from standard over time it's probably lost 5 - 15bhp so getting 130 out of a 1.3 would be like finding rocking horse shite :lol:

[Mark]

Huw Beynon's Focus 3 Rally car is a 1400 16v corsa engine with all the adjustments and throttle bodies. It produces 160 BHP.

[benji]

have a look on www.usedrallyparts.co.uk or www.motorsportdirect.co.uk, and keep an eye on the clasified section of the motersport mag that comes out on wednesdays(cant remember the name) there is always engines for sale

[Dan]

Figures mean diddly to me now adays as they are soo unreliable due to the variation around the country and different r/r's. I helped kinda prove this point and suprised myself recently. They are only meant to be taken with a pinch of salt as even the r/r peeps themselves can manufacter a good result to make themselves look good and keep your custom.

Spam is very good at tuning the nova's but i always knew his figures were dubious. The car went well on road so i knew he did a good job but a head and cam didnt = 150bhp lol. Also as an example this engine with injection, head and cam was 4 bhp at wheels less than i have now. One of me mates has the same mods i used to and runs similar power. On the road i absolutley kill him. I still use spam from time to time as like i said he can get em to go well and is a top bloke, i just dont quote figures

[Dan]

also remember this post was about how it was possible not if it was. It might be possible to almost double the engines power by adding a further 60bhp or so but it would cost money (lots of), the gte engine is capable of 180bhp but i could never afford to take it that far and make it usable on the road. This is the equivalant of what you are asking for from the 1.3 engine.

[MC]

Dan,

I don't think trying to get 130bhp from a 1300 is anything like trying to get 180bhp from a 1600. A 1300 in good nick will rev high, so using the right, chokes, cam and head combination along with twin 40's will make it possible. You could probably get more, but you'll start inheriting the characteristics of a 16v engine on TB's.

If you want 130bhp, do the following:

Have the bottom end sorted, i.e. crank re-grind and re-bore using new pistons - Shouldn't be much more than ?300.

Get a decent cylinder head, such as a Blydenstein B++, or speak to him and tell him your plans and he'll custom make to suit. ?460

Get a 285-290 deg cam. ?175ish + followers. (or use a 300 deg cam with solid lifters)

You've gotta have twin 40's and be looking towards 32mm chokes. ? second hand for ?200.

Competition 4-branch and system - ?202 from Motorsport Direct

If you can't strip and build engines yourself, add on the cost of labour and then around ?100 for set-up.

Once its set-up, you should be around the 130bhp mark at 7-7.5k rpm, if not, play with the choke size. Each size you go up, you'll gain bhp, but loose low torque. You don't have to go up in 2mm sizes, you can machine them 1mm at a time. Find the right balance.

If only it were that simple :!:

You make it sound soo easy :roll:

[CP]

100 hp per litre is an achievable bench mark to aim for on a N/A 8v but all the small details need to be right as well as the big ones.

[MC]

It is that simple, but unless you can do the building yourself its gonna cost well over ?2k.

I can do it if you want a quote, the only problem is you'll have to join the waiting list that is going well into Novenber now.
