Right, due to a few financial issues, most of my toys have to go on hold for a while. This does mean I can keep my nice 205 GTi. However, since it'll have to replace the Indy Bird I need it to have a little more pace. It was measured at 170 BHP on Emerald rollers. but I feel a little extra could be extracted. I'm looking at pulling the engine to give it a bit of a refresh (new rings etc) and was wondering what could be done to aid the later installation of a blower? I don't know this engine very well, so don't know just how much the standard rods/crank/head etc will allow on stock parts.
Any ideas or suggestions gentle(wo)men?
PS, anyone know what a safe redline should be for this engine?

bin the mi16 and get a low mileage gti6 lump and supercharge that, have a read on the gti6 forum - http://www.306gti6.com/forum/showthread.php?id=69404&page=1

Have a read through the Puma Racing website for excellent general tuning info and this Pug Mi16 Engine article for specifics (doesn't cover supercharging though).

A few guys in the South Yorkshire Pug GTI Club turbocharged the standard engine with success. Trouble was you couldn't put the power down effectively....

One guy from Kippax had a beaut Red 1.9 which he lowered (very tastfully) had a Sebring exhaust... went over a slight hump in the road, may have been a Hump Bridge and cracked both the sills in half. Gorgeous cars, if a little thin!!

The Mi16 was always considered one of the poorer designed engines (well - head)... sorry

Steve

Thanks for those links gents, I'll get reading
Steve, why do you say the Mi16 head is a bit poo? Most of what I've read says the exact opposite.

Right, I've read through most of that supercharger thread, and it looks quite good, but more money than I want to spend. Since I already have an emerald and Jenveys on mine and I'd like to keep them if at all possible, does anyone know of something that would do the job?
Also, why bin the MI16 and get the GTi6? Is it better able to handle the boost, or just a better engine somehow?

Might also be worth looking at things the other way and identifying areas where weight could be saved. Ditch the spare wheel and get breakdown cover, lose some interior, perspex window kit, cardon fibre bonnet, no stereo, tyres, wheels...etc.

If I had a free choice, I'd keep the Indy, but it's a right sod to drive in the wet and I do occasionally need to take the wife places, so I need a roof and a seat she fits in! Sounds like tuning the engine to a higher NA state may be an easier step for now as it's standard internally, and I was planing on shedding a bit of weight where possible. My cars don't have stereos and so on, as I'd rather hear the engine sing. It already has most of the go faster bits, but I do want a bit more, and I may even sell the NOS kit to help fund a new head/cams.

Anyone have any experience with cammed Mi16's? Any that are a good usable cam, or any to avoid? Low end powers not too important, and I like a nice revvy set up, if that helps!

Damien: That is a bargain for that kit
I have looked into rotrex gear before... seriously flabbergasted at that price.
Edit; No proof....though might be fun to try it.

Hi si,if you have a look in the yellow pages there is a place in brackley that specialises in pug i think called pug one off,
they just had one of their cars a 306 featured in practical performance cars the rolling road work was also done at emerald,its running TWO V6,s!!.
They also had a turboed 205 featured in max power recently, they might be worth giving them a ring.

Cheers for that, I wasn't aware of anyone round here who specialised is pugs. I'll have a look and see what I can find.

dont know too much about the mi16 lump as ive been with the gti6 for 4 years.

from what i can make out the mi16 isnt great when pushed, it suffers from oil starvation but the gti6 dont, also the heads are better flowed on the gti6. from what ive read the mi16 engine responds better to breather and head mods (unlike the gti6) but the mi16 is starting to get abit old now.
i did read that the s16 lump would be better for boost as it runs a lower comprestion and it is similer to the T16 block (as in the 405 T16).

my gti6 engine is running gsxr throttle bodies, kent cams, hi-flow head, forged pistons and rods, ARP bolts, solid lifters, Lightened Flywheel lightened crank and kms management(limiter on 8k), last time she was on the rollers she made 223bhp @ 7620rpm, you do they same line of mods to a mi16 and you should see more power.

the chap with the supercharger kit has been running for over 6 months now with afew trackdays with just over 400bhp, to have the same type of setup as him your looking at close to 10k.

Looks like a better head and cam s is the way forward then. I'm looking for some extra power, but as ever, don't want to spend too much. Definitely can't afford 10K for the full blower set up! About a grand I could do, but not a lot more at the moment.
