XSI 8v to XURS 16v - RWerner - 19-04-2017

Hi. I'm newbie here, and about mechanic too.

I'm a 306 xsi owner, and i want to upgrade my engine at a low cost. So i think: "If my engine is a xu10 i could trade some parts for the GTI and have a good improve".

Somebody know if is it possible?

you basically need everything from the engine bay of a gti6.

engine, manifolds, wiring loom, all coolant hoses, radiator, downpipe, ecu.

wow... The radiator too ? Its a lot of work and money ^^

you could put the manifolds on, possibly the head but surprisingly there arent many similar parts.

16v manifolds don't fit 8v head...


only similarities are crank and block casting.

In Brazil there's 6 running (max)

Tnx for all help fella.

I think it will be very hard to find a GTI or VTS full engine to sale.

Any other idea to up from the 122cv to around 180cv without a turbo?


RE: XSI 8v to XURS 16v - welshpug - 20-04-2017

throttle bodies, forged pistons, long duration camshaft, double valve springs, custom exhaust manifold.


RE: XSI 8v to XURS 16v - RWerner - 20-04-2017

Crazy idea, but...

Is a swap from the 1.6THP engine to my 306 possible ?


RE: XSI 8v to XURS 16v - Midnightclub - 20-04-2017

Possible, probably.. but not sure what you'd do for management. Would probably be more expensive than shipping a GTI6 engine to you from the UK or elsewhere (if that's legally allowed where you are)

I have no idea about the cost of a gti6 out of Brazil and Ship costs and taxes... And none if it's possible import it.
Otherway, the thp is possible to find, but will cost  2x my car value ^^


RE: XSI 8v to XURS 16v - Midnightclub - 20-04-2017

I think the 1.6 THP is direct injection and has variable valve timing so aftermarket management would be difficult to find at best or very expensive. Then you'd have to get someone to actually do the mapping for you.

Good point !!!

Tnx again Rofl


RE: XSI 8v to XURS 16v - Midnightclub - 20-04-2017

No problem. A 1.6 16v J4 engine may potentially be a better bet depending on how many aftermarket parts can be had where you are, there's tonnes of parts for them available over here and across europe. Standard though it probably makes about the same power or slightly less than your current engine but may be lighter
