1.1 spi bottom end 1.4 spi head

[Jonny-R]

Is it possible to have a 1.4 spi head fitted to a 1.1 spi bottom end. And can the 1.4spi head be mildly cammed, as far as I know the 1.1 head can't be.

Cheers.

[RallyeDan]

the 1.4 head should fit pal, but you might as well fit the whole engine. Look on QEP's site for cam listings:)

[Jonny-R]

Cheers for the reply Dan. I'll find the model number of the engine and see if they have camshafts available for it..

It just seems a lot easier to change the head. Get a nice new headgasket on there, whack the new head on, without having to remove the engine.

I sort of want to see how much bhp a 1.1 could make. Could be fun and cheap.

[RallyeDan]

1.4's have a different bore and stroke to the 1.1 engine, stick a Rallye head on it instead for a proper gain:)

[Jonny-R]

Which Rallye heads would fit remember I'm spi.
Am I looking at 1.3 head and inlet?

[Crooksey]

Mate ill be selling my XSI engine soon, interested? :p

[Jonny-R]

Think my parents would go spare if I came home with a whole engine - haha. And I don't have the skills to swap a whole engine over.
But how many miles does it have? How did it go when you went over to Bluewater?

Cheers.

EDIT: And what are the plans for your car. Valver it? You got the OMP bucket(s?) in?

[Crooksey]

I didnt take it to bluewater, i went with charlie in the end.

The engine has covered 100k, and after fixing the front suspension, I took it out for a day and it was beating cars such as...

Golf GT TDI
Gold TDI 130
Someone in a 106 GTI who tried to take me, So i showed him the 8V power horse :p

It runs nicely from what driving I had from it.

My plans for it are the bottom end of a S2 rallye / VTR (its the same block), then rebuild with low comp pistons and supercharge it.

Hoping to have it ready for next year's track season.

And got some cobra buckets in.

I personally wouldnt bother messing to much with your 1.1 SPI, the money spent wont give the same results as a new lump would.

[Jonny-R]

Sounds good, the XSi engine.
I just fancy doing some fettling, see what I can get it to. It will be cheap and easy before I move on to bigger things.

Thanks for the input I'm going to think things through.

[RallyeDan]

you'll have to use the 1.1 drivers engine mount though Jonny, as its very different from the XSi one, splicing of the looms is also needed

[Jonny-R]

Yeah, that type of stuff I know I can't do.
Would everything on my engine be compatable with 1.3 head and inlet, to get in plumbed in relatively easily?
Any idea how it's going to idle?

[Dave-R]

Mate, just source a 1.3 Rallye head and inlet! It'll be interesting to see the results, a little different, fairly cheap to do. We could probably manage it over a few weekends :D

[Jonny-R]

Be good to know it'll work first mate. :D

[Dave-R]

Everything will work with a bit of fabrication. Just pack it out with washers.

[Jonny-R]

LOL sounds familiar! Anyway..

[Gina_G]

don't do it, bores will need reliving for the valves bit of a paint.

XSi / 1.3 rallye btw I do know of a 1.3 for sale complete with loom and ecu to

[Jonny-R]

Gav to the rescue. So I can't swap the head? That's extreme-gay.

OK, so I better start planning for an engine conversion. But won't be as soon as this would of been.

[Gina_G]

1.4spi will fit just use the inlet and tb aswell mate, as to gains you will notice something

1.3 head and inlet would not fit without alot more work

[Jonny-R]

Thanks for clearing that up.
Would you recomend sourcing a second hand cam for the 1.4 aswell, worth it? One that would only be mild so not need a remap or owt.

Be fun to rolling road it all this summer and see what it gets.

[Gina_G]

tbh I wouldn't bother with a cam just use the 1.4spi head, inlet and tb probably kick power up to 70bhp with the usual mods ontop, get a nice bit of torque aswell

[Stevo_106]

will this actually work? lol im thinking down the same lines, want to squeez wat i can out of a 1.1, and if you managed to fit the 1.4 head is camming a posibility?
