what sort of mods would be involved to make a 1300cvh (new) reach over 100bhp??
every part would be great to know
cheers

[Dave106gti]

A different engine mate, or possibly a Van-Aaken turbo kit (designed for the Ka), sorry but i wouldnt have thought they're a very tuneable engine

[FezzR]

just curious where u got a 1.3 cvh from?? what were they fitted in

[ace]

its outta 1300 orion, which seemed quite fast and was fully reconned, its pistons are the same size as an 1800 zetec but got a short stroke, i thought that this combination would make it a very tunable engine, wotsmore is that it has 70bhp with a vv carb wheras the 1300 ka and endura engine is only 59bhp , bit of a difference.
i was told that by fitting twin 40's, a 1600 cam (Xr2) gas flowing, overbored pistons and lightening the bottom end it would send it to 100bhp, is this a lie or true?

[bassboy]

ace its VERY hard to say ur car will push xxx bhp by doing these mods...each car is different and will react differently to every modification...as a guide heres whats been done to my cousins XR2:

gas flowed and ported head
high comp pistons
high lift cam
twin 40s
magnex exhaust

and he is hitting 120bhp...and thats a 1.6 so u can use that as a rough guide...just remember u have 300cc less!

why spend so much money on a 1300?? just save and go out and buy an RS Turbo as this will work out cheaper.

[Mark Si]

I disagree Prit mate, by the looks of things RS Turbos are an absolute pig to keep running, just look at the hassle AndyBlack has had

Swap the engine for an XR2 CVH, strip it down, clean it up, maybe have the head and bottom end worked on (balanced etc), fit a performance mainifold + exhaust system, bigger carbs and you're laughing

[ace]

trouble is that i want to be different and get a 1300 cvh to over 100bhp naturally asperated, apparently a kent cvh32K camshaft kit will give the engine and extra 14bhp, any thing else like this would be great to know so that i can get the bits and put it to a test.

[chumkila]

Mark, if u get a job done correctly then reliability does not come into play.

P.S. i'm not saying Andy didnt. Its a general comment.

[Mark Si]

Ok mate fair point

[xr2i 1649]

it is going 2 cost a lot and u do not get a lot back
100bhp is not a lot and u can spend a lot of cash
2 get it then some kid the has a xr2i that he spent £600 2 by will
spank ur bum
so i say just do some small mod's and have some fun

soz 4 the spelling just got in from the pub

[bassboy]

its a chance at the end of the day...only way ur gonna get the reliability is if u spend money on the MAP...only then can ur car be truely reliable...BUT saying that...it also depends on how u drive it! For example, Sunnys car has been mapped various time by top mappers hence y no engine blows...and he sexually abuses the car practically everytime it comes out ...but hes spent the money on a VERY good quality map which he knows (touch wood) aint gonna let him down! But if he got it mapped by a not so good, im sure his engine out be out a number of times with another engine rebuild etc etc...especially with his driving style

bassboy

[chumkila]

a quality map's output is only as good as the engine build.

[Phil Si]

chummy old boy i'm confused... u tell this guy to get a bigger engine and work on that yet u told the guy who wanted to turbo a 1.6 zetec( ) to go ahead and do it? i hoped u were joking?

Ace

you say your engine has a large bore and short stroke

there is another very high powered 1300 that has this combination and can reach 200bhp+ easy

its a Suzuki GSXR 1300 hyabusa engine

but this would do fook all in a car the weight of a fiesta as it has

NO TORQUE

you can get short stroke engines that kick out high power and i na motorbike and light kit car great

but fiestas are rust buckets you may see high BHP figures on the rollers but the car wont be as nippy as if you spent the money on a XR2 engine and did some playign with it

[ace]

ok so my engine wont have much pulling power, so what if i installed a close ratio box? surely this would make the world of a difference, id just loose top end. ok so uve got a fair point about the torque factor, so if i was to build a 1600 then what would this do to my insurance and what sort of power should i expect to see?

[Fezzy Turbo]

I disagree Prit mate, by the looks of things RS Turbos are an absolute pig to keep running, just look at the hassle AndyBlack has had

Well, to be picky.....things could have been done better.

As for Bassboys quote on good mapping.....well i only have a cheap Superchip stage1 and i thrash my car.......Chum has it right.....the build has a LOT to do with reliability + the set-up.

137k and still going strong

cheers

the 1300cvh is exactly the same as the 1600cvh but with a shorter stroke. the shorter stroke should in theory make it more revvy if done properly. and with the right choice of parts I am sure you oculd get close to 100bhp if not more.

BUT it will cost you an awful lot of money to do as to get 135bhp from a 1640cc cvh it cost me £1500+ for the engine alone.

If you want to do it to be different then good luck to you as being different is always refreshing.

I would suggest you look at compression, cams, headwork, and fueling - twin 40s would work BUT you would have to down choke them quite a bit to get them driveable.

As for the gearbox, yes this is also worth doing as most people tend to bolt an old rst box they found at a scrappies on, but choosing the right gearing with a series one lsd and final drive (4:1) will make your gears very short and close and will definately help you in performance terms!

Good luck with it!
