weird question, how would a 1.8t run without the turbo

[pat57woods]

I have rabbit pickup that I race on the dirt oval. Last week I cracked a piston in my 8v. I have been given a 2000 passat with a blown tranny. Track rules don't allow turbos. Here's my options/questions

Run the 1.8 without the turbo- Question, how will that run?
Can I use my carb intake on the 20v head? would I want to? My 8v head has a pretty nasty cam.

If not a good choice or not possible then will the passat short block work with my 8v head?

Thanks in advance

you "could" build a 1.8 (non-T) NA by running more compression and a standalone system tuned for it. You'd want a higher comp ratio and much more stuff though.

[Vegeta Gti]

you can get 10:1 and Stroker set up. then add the n/a intake cams that are out there. AD some itb's and good tune on 100+ and you could make 200 whp with decent torque

there are a few n/a threads out there

PM me if you have any questions or are serious about building one. (the motor is for sale )

VAG actually made a non turbo 1.8 20v motor.

I'm not looking to build an engine. I have a race labor day weekend. I want to know if I can pull the engine from a 2000 passat, bolt it up to my caddy tranny and run it without the turbo?

[Vegeta Gti]

the quick answer..not at all. you need management wired in to control everything, and obviously a solid tune.

[GLIguy85]

and even then it would have zero power. if you made some sort of exhaust manifold to put in place of the turbo, you might be making 60ish HP.

You need to source out the AGN exhaust manifold or make one. You can swap the ECU and everything it should work fine. Only hard part is getting a tune. I'm sure any tuner would make you a custom file for a price.

[pat57woods]

So even with the complete running passat to steal the wiring, ecu, etc. Id be looking at 60 hp? I didn't think losing the turbo would cost me 60% of the stock hp.

[Vegeta Gti]

noonoo, it would run like completel dog ****, but if, say you had standalone an dhad it tuned and the hardparts like a proper header,etc...you would probably make around 130-140whp.

[pat57woods]

Forgive my ignoance but what do you mean by a "standalone"?

[ArcticFox]

Stand-Alone is an Aftermarket ECU.

[pat57woods]

Can I use the short block with my 8v head?

[AmIdYfReAk]

No.

[Vegeta Gti]

they don't mate very well.

this is what i gather from the posts...

your grasping for an easy bolt in solution. this doesn't happen, period. you need to bite the bullet and build, spend some cash, or settle with something much simpler....which is relative as you want to swap so it still involves some work/money,etc


the n/a 20v can be very cool, can rev the living **** out of it with some springs/cams and with a good itb/header setup with some compression make some gnarly power.

hence the threads i posted above...

[ArcticFox]

I'd say just get an ABA Short Block. Use the 1.8t motor as trade bait. You should be able to get the ABA and cash/trade.

Indeed, or a 9a... Still wouldn't be able to use his cam, but it would have more pinch Imo.

that is false. with a good tune on standalone you will not make more that 90whp. I built a 2.0l 20v with headers the first time with all stock parts using a 9a block so i had 11.1:1 comp and still only pulled 98whp (120wtq)

that is why I stated that with a 1.8 block and 9sh:1 compression, you will make crap for power

I am uniquely qualified to answer this...

My '98 Passat (AEB) had, essentially, no turbo for a very long time. 0-60 took fourteen seconds. It drove like it was towing a boat. If you stayed in the higher RPMs, well, it was still slow. No CEL or codes. It drove just like you'd imagine a 1.8 liter engine would.

Why? The wastegate flap fell off into the cat. After I put it back on, and with the GIAC chip, it now runs like a cat with turpentine on its anus. And gets 25 MPG while being flogged every day.

HTH.

Thanks, that was the info I was looking for. The only difference is I would be running an open exhaust, not a blocked cat and my truck weighs under 2,000 lbs while your passat weighs over 3,000 lbs. So I think with only one week until the race...it's worth a try.

Here in Europe we had 1,6 1,8 and 2,0 N/a engine options in the mk4 shell.
hell, they even came with Haldex as a option. In other words, we can get dirt cheap
mk4 chassies with oem haldex

Here in AMERICA we have McDonald's and Wal-mart every half mile. And everyone drives PICKUP TRUCKS!


You got any room over there in Norway, man?

So, to throw a wrench in the idea, what about if someone (me) had Maestro and wanted to run NA for a month or two to break in the engine? Figure SEM, intake cam, 9.5:1, and an exhaust pipe coming off a T3 bottom-mount - are there any known tuning settings for an NA that we folk could use to get the thing running while saving for a bling turbo?

All hypothetical, I plan to get the damn turbo, but I've wondered about this topic as well...

[GLIguy85]

in theory, yes. i dont know if its possible with the eurodyne software and you wont make much power but it could be done
