A phase 2 rallye 1.6 8v, with cat cam, carbs, 4 branch manifold, pugsport system, do you think 145bhp is attainable?

If properly mapped. yes.

Or keep the injection and get a remap with those mods and get the same kind of power (i41 on DaveP's old S2), or use an S1 manifold too for better sound and better poke aka Peter86 and a couple of others.

IMO no point carbing it unless that is what you know.

It's the usual expected output now with those mods plus S1 inlet, enclosed induction, remap and general maintainace. 145 fly and 125 wheels.

Now that the S1 inlet problems have been resolved the power out of the s2 is realiable. I think i'd be right in saying any more power would cause reliability issues and you probably will have to uprate the engine internals!

I would suggest changing the vlave springs and having the head totally reconditioned so that it's ready for the power increase. Change the cambelt, tensioner, water pump and alternator belt to make sure they are good for it.

I'm not overly familiar with carbs, apart from those on my motorbike. Gettin the Shenpar R6 carb kit, with mechanical distributor, can fully set up the ignition etc this way.
With just putting an S1 manifold on it, i have heard of people losing power, threads i have read on here, so think carbs would be more reliable.
Carbs are cheaper to set up than throttle bodies, and much cheaper. My only concern is cold starting in the winter.
What other modifications would see me decent increases in power apart from the ones listed above?
The bottom end is good for over 160bhp surely, with the oil spray jets under the pistons etc?

i think the people losing power with the s1 inlet were those who didnt get a re map, im not 100% tho as tunings all a bit new to me

Yeah all the sensors on the S1 although similar are sending duff signals and the thign needs remapped, hence what seems like a 70 interesting upgrade turns into a 500 remap...

Go S1 manifold and keep the injection else you are taking a step backwards, I am even considering saving for TB's for my old pinto as they are just superior and the way things are going work out about the same price as a good condition set up pair of 45's.

it is possible, but you would need headwork aswell. me and peter86 have the same spectongue out and we both 144-145. but it costs quite abit to get there !!!


but its worth it !! :veryhappy: :steer:

everythign costs cash, I have a 2K Pinto sitting there doing nothing as it needs another 2K thrown at it....

Basically if yo are going for a 145bhp spec 8 valve then do it from teh ground up I think is the recommendation, else you may not get any bennefit...

To get a Rallye to 145 BHP is it best (cheapest ;) ) to:

16 valve it - then 421, Pugsport, Cams, remap.

or 8v. 421, Pugsport, Cams, Headwork, S1 inlet, Remap.

how do the 8v engines tuned to 145 bhp compare with the 16v lump just with breathing mods on road and track ?

Robsparky

flying blind - 16v is cheaper to tune than 8v

leeds vts - 145 bhp 8v vs 125 (ish) bhp 16v = 8v

Carbs on the 106 will always be compromised due to the available space. Tb's or an S1 inlet for decent results only IMO.

Standard Rallye valve springs are in my experience safe at 8k with a 280 catcam, no need to upgrade unless they're very old or a more severe cam is to be used.

I changed my valve springs with new peugeot ones, as they had done 80k and Slik and the cylinder head guys said to do it aswell.
