205 engine ideas

[nellyleelephant]

The time has come to give my 1.9 gti the power it deserves!

I have only really considered the mi16 conversion, mainly out of ignorance.
It appears there are other options though!

Anyone have experience of doing a GTI6 conversion? pro's and cons.....costs?

Cheers

go to 205GTIdrivers.com. It's all there.

However you could Mi in or GTi6 it, depends on what you want the car for?

Mine is still a 1.9 8v but sporting a BV head with twin 45's and a lumpy cam. However it's not for the road, track bias only really (although its a hoot to drive anyhow)

Cheers, unfortuntely work won't let me look at 205gtidrivers

Is the 2.0 litre 8v turbo that was fitted to the 406 an option?
150bhp as standard, but i'm guessing the turbo adds a certain amount of adjustabilty.

[TEKNOPUG]

200bhp is readily available without much work.

Slightly more involved than a 16v swap as you have all the plumbing to contend with. has been done many times though, so not really an issue. Totally different animal to a 16v.

[nellyleelephant]

More torque, less revs?

[TEKNOPUG]

Yep. Depending how you have it set up. Big rush of torque upto 6k. Obviously a lot depends on the mapping as to whether you get an old-school "laaag.....wait for it....WHOOOOSH!!!" delivery or a constant V6-like smooth power delivery. Either way, you'll be fighting torque-steer without a decent diff.

[nellyleelephant]

So the 8v turbo route could mess with the otherwise great handling?

Perhaps turbo isn't the way.

I've done some interesting 205 conversions, 3.0 406 Coupe' V6 (fwd), 4.0 Lexus LS400 quad cam' V8 conversion (rwd Supra box, moved the bulkhead back eight inches, made a tunnel and used a Granada Scorpio rear diff and hubs), Mi16 4x4, rear mounted 2.0 8V Turbo (Dimma wide arches etc). You can fit any engine into any car. Don't worry about the purists. How about a rear mounted Rover 220 Turbo on an MGF gear box, some choice parts from AN racing and 300 reliable bhp will be sat on your driveway. Whatever you do let us know. Rob

arent mi16's getting scarce these days? I know my mates been hunting around for one for a while now.

Wow, some interesting stuff there!
I'm not sure i want to go to the level of work that you've obviously carried out, but the 3.0 V6 sounds interesting.
Is that engine a lot heavier than than a standard 1,9? I know it will be, but how much heavier??

Not really. Depends how you drive it. Also the power delivery is dependant upon mapping, cams, gear-ratios, LSD etc etc etc. Iron block turbo is a bit heavier than the alloy XU9 but then so will the GTi-6 engine. Unless you are a racing driving going at 9/10's everywhere, you won't notice it though.

An 8k rpm screaming 16v conversion is a lot different from the original 8v GTi, doesn't mean that the handling will be compromised.

MI16's are getting scarce (or rather, harder to find). TBH, the GTI-6 engine is probably the better route for 16v power - more plentiful, more modern, greater stock power and tuning potential. Only downside is the iron block, which is negliable anyway.

I kmow a guy who married a subaru and a 205 together, i am not sure of al the technical details.
Keep us posted on the outcome, it all sounds imteresting.

I only really know about the Peugeot engines, but I would never consider anything other than an alloy Mi16 engine.
Everything else I've been in (GTI-6, 2.0 Mi16, S16, 2.0 8v T) just feels too front heavy. Fast, but in my opinion that misses the point of the 205 GTI. If you want to go fast in a straight line, this is not the car for you.

Where have I said I want to go fast in a straght line?? quite the opposite actually.

I never said you did. I just think that's what the iron block engines transform the car into...

I have only driven one MI 16 205 conversion and i agree about going in a straight line comment.

Any pics or a build site for the V8 conversion? Sounds very interesting indeed!

I like teh idea of the rear mounted engines as well... T16 style.

[MINIrocket]

From the car's i've been in, for a decent and fun road going 205, you need a decent powerband. That's plenty of torque and decent bhp, but as has been said, without making the front end too heavy.

On a strict budget i'd go for a mildly tweaked mi16, or a decent tuned 2.0 Turbo. If you've got a decent budget above 1-2k then your options open out wildy!

Oh, and don't strip it out unless you only drive it to and from the track... my stripped mi16 isn't fun at all on normal roads!

[nellyleelephant]

I certainly won't be stripping it out.

The main reason for the change of engine is that my standard 1.9 is a bit leggy and it either needs changing, or rebuilding. The idea of a bit more power is appealing.

I still need a relatively practical car at the end of the day.
