View Full Version : I have a question about a FSI to TSI swap

Do you guys think the TSI would be a direct swap for a FSI in a '06 GTI?

I was just curious because a friend is talking about buying one to build (cheaper parts, newer motor, fewer problems) then sell his FSI and drop the TSI in. We have tried searching but couldn't find to much info or anything about it being done before.
any info/help would be appreciated

You'd need the ECU, probably the wiring harnesses, coolant/fuel/vacuum lines, and engine sensors (MAF is different, others as well). This would be a lot of work and money for very little/no return. Maybe if you bought an entire wrecked TSI car/front end, you could do it semi-reasonably.

Bad idea all around. Waste of time and money IMO.

If you want to spend all the time and money to do an engine swap. Why not go all out and put something badass in there instead? Or just build the crap out of the FSI?

It would be like doing a k swap in an EF chassis... a shit load of work...

Agree, at the minimum I would go with R32 3.2L swap. You'll get the 4 motion and a kick arse sound. I understand why you want the TSI though, it could be had for little amount of work but then again, you do little, you gain little.

Itd probably make the most sense to build up the fsi or your friend to trade in his car for one with a tsi.

What would your rationale be swapping for a TSI? If it's for the cam follower, theres the h2sport fix. Aluminum valve cover? There's EJ valve cover. with those two mods your FSI will essentially be bullet proof other than carbon build up.

h2sport cam follower...how is that coming along?
Carbon build up will happen regardless of TSI or FSI.

Hell even places around me will do a complete cleaning for carbon for 3 bills.

We've done the swap before on the race cars and it required swapping the motor, full wiring harness and basically everything attached to it, including the cluster.

Don't waste your time and money. Buy a new car.

ok thanx. He says he was looking into it because he is near 100k miles so he is looking at different options. because he doesn't want to finance another car for now. I figured it would entail more than swapping the engine and ECU but he thought thats all it would be, now I can show him I was right.:biggrin:

Convert to rear wheel drive and drop in a late model 'Vette engine. Probably would be easier.

Yeah dude for the cost of this you could get a hpfp and a ludicrous amount of cam followers.

your friend is a retard

buy followers and suck it up, or sell/trade for a tsi
