Considering upgrading my setup to something like that. Most likely a ARtech ramhorn manifold/hot parts + EFR 6258. Goal would be around 250-260 on stock motor, if it blows rebuild it forged and push more boost?


Is it a terrible idea overall? Everyone says to just get a 1.8L but changing the motor frightens me and finding one locally would be a PITA.


Opinions?




Thanks all!

you're willing to shell out like 1200 or whatever it is on an EFR yet you're afraid to upgrade to 1.8? lol
no replacement for displacement.

The EFR is closer to $1600 I believe, if you can find it in stock.

I say go with the 1.8 swap. Honestly I think that building a 1.6 motor is a waste. The parts for a 1.8 are the same cost and you will end up with more displacement which will always help. You also have a much wider variety on the choice of heads you could use.

1.8 swap plus my setup and you will be set for life.

But I think the efr would work fine on a 1.6 as well. You just have to consider when you do eventually step up to a 1.8, selling your 1.6 stuff is a little more difficult.

Actually doing the motor swap is what scares me, never done anything like it. Plus I don't have a full garage I can park it in. I've taken the turbo/manifold and all out and it wasn't too bad. Where can I source a 1.8L anyways? I know I could buy a built one from Savington for like $4k... don't think I can get wife approval for that though. :(

Stock 1.8, tiny intercooler, the WORST log manifold I have ever seen and a Link = 270whp @ 12psi

yeah I've read that thread roughly a couple times...

Then what is it is exactly that you are asking? ARtech parts w/ EFR = stock motor blowing power at low boost.

Also, I have to agree with sir Vlad and sir Virgil, 1.8 swaps are easy. I would never do it though

What's a 1.8 cost and what's it worth? 10hp N/A? Is the difference more when boosted?

I guess mainly has better aftermarket support, quicker boost, better flowing heads

Honestly pulling a motor is not that hard. You could easily do it in a weekend if you have help. Hell with help and a good idea of what you are doing, you can do it in a day.

Agreed. I pulled my rear diff, trans, and engine by myself never having pulled the engine before in less than 10 hours. You got this.

they perform significantly better in boost and have better available upgrades (e.g., IMs, heads)

I refuse to build my 1.6L because I consider it a waste; they require so much more boost for what I consider poor results.

for example, I've seen a built 1.6L with .040" over pistons running a 2871 and custom IM pushing 17psi make just around 270rwhp. Meanwhile, I've seen a stock 97 motor with a BEGi IM and 2560 make 275rwhp with only 14-12psi and had a significantly better torque curve and area under curve.

Cubic inches are like dicks, ****, and stacks of cash. Bigger is better.

It sounds like deep down you want to upgrade to a 1.8, and just want us to talk you into it. Just do it and never look back.

Looking into somewhat local part cars... Now just need to get home frmo my deployment and buy one. Money is the easy part, talking the wife into it and storing it somewhere; THAT'S the hard part. LOL

I also wouldn't ever put a $1600 turbo on a 1.6L.

Ok as expected I have been convinced to do a 1.8 swap. My question is how hard would it be to go from my 1.6T to a 1.8 NA as far as changing my tuning? I haven't messed with the MS much

since you are not using the stock ecu, I would think the 1.8 conversion should be cake. Just do the reroute and get setup for an oil cooler while the motor i out.

I don't know about the tuning for the MS.

Damnit Brainy, you just talked me out of rebuilding my 1.6.

Damn youuuuu!

lol. I mean, I'm also just content with 240rwtq/ 240rwhp.
