More power

[Topmanbeny]

Is it worth the hassle power wise to bother putting a 1400 block on a fairly bogo 1300 sr ? As I'm gaining its about 5 hp if that

[mowgli]

its worth more like 10hp. but what is actually wrong with the 1300??

[Adam]

No

[mowgli]

OP, finding some brand new 12st pistons, and boring out the 1300 block to fit them will make a lot more power, cos it will make 11:1cr.. but they are getting rare these days

^ im with mowgli... the 1.4's nice, with a wee bit more power and torque, but as he says, If the 1300's still strong, you might as well keep it

[Topmanbeny]

The 1300 is mint absolutely sweet as a nut just wanting more power , and there is no short of low mileage 1400 blocks ( mainly thanks to auto corsa b 's ) so thought it may be a good mod without the expense of big boring

[jimbob-mcgrew]

do you wanna keep it smallblock for the cheaper tax band and petrol ?

I was gonna suggest a cam, for a slightly more aggressive rev band. but for the price of buying and fitting it, you might be able to pickup a 1.4 for nearly the same money.

I hear the 1.6 16v is a bit of a beast, but then your crossing tax bands, and have to faff about changing petrol tanks, fuel lines, re-wiring and all sorts, and will cost a fair bit more.

you could always stick with the 1300 and rag the nuts out of it lol - your call !

[Topmanbeny]

I'm considering a cam as well , Im trying to keep it in looking unmodified and without really looking for it I don't reckon
You would be able to look at it and know those bits were there

first priority is a decent ported head.
then get a camshaft reground at somewhere like autosprint..

then get it set up properly by a decent old school garage...

you could swap the carb to a weber replacement.

it would take a lot of looking to find any of that once its fitted to your car.

it would also go rather well...

fitting a 1400 bottom end from a corsa would stick out like a sore thumb, simply cos of the engine no.

[jimbob-mcgrew]

might have to do the same to mine :P

[Topmanbeny]

Many thank for the advice mowgli going to look up autosprint now , is the head on the 1300 sr not pretty good any way and there for difficult to get much better for a fast road purpose ?

[Topmanbeny]

And jimbob I would love to c16xe it but I stumbled upon mine and found out it may be the lowest mileage mk 1 sr left so i can't over mod it really as much as I may want to :-(

autosprint is in birmingham,

and the sr engine is absolutely bog standard gm 1300... getting it ported & fitting valves from an e16se/c16se would really make it breathe well.

[Topmanbeny]

Awesome shout to go to auto sprint mowgli , very nice , very helpfully and rediculously well priced . He advised me on a 290 degree camshaft and followers , I'm slightly woried 290 sounds a bit much for fast road ?

[mowgli]

i think it will be fine on a 1300 carb engine.. its got no emissions crap to worry about

[Topmanbeny]

I meant from a ticking over / driving point of view , I'm expecting it to be a bit more lumpy but didn't want it to be a dog to drive around

[jimbob-mcgrew]

290 sounds good. it shouldn't run lumpy if its set up well

[Topmanbeny]

Awesome , last question on this topic can you set it up ok without a vernier pulley?

[chrisd1986]

Cam, twin carbs and a decent exhaust system

[mowgli]

verniers rarely seem to improve things on a single cam road engine
