2.0 crank in a 1.8?

[yousaidpoo]

I'm probably getting ahead of myself here, but i was at a motor shop downtown that specializes in L-jet engines. They tune them up and race them in beetles. I asked the guy what all they did to them and he said all they had to do was put in:
-2.0 crank
-2.0 pushrods
(just those 2 things gets it up in the 110hp 130lb-ft area)
-96 pistons
-cut heads
-switch to dual weber 44's, 48's to make it a drag car
-He claims 160hp and about 170lb-ft with all that.
-Guy also quoted me about $450 for a 2.0 crank and rods.

My questions are A) is that a good price for the parts B) would it be worth the money for a daily driver/ occasional autoxer and C) if i were to do the crank and rods, leaving the stock L-jet would it work without tuning, would i need to change a bunch of stuff, or would it be more beneficial to just switch to carbs?

I dont know when or even if i will pursue this, but i will post if i do.

definately worth it.. I have all the goodies you'll need to do.

A) that's not a bad price, check aircooled.net too if you are a DIY'r... or get a kit from Jake! the crank/rods alone is only the beginning of the money you have to spend

B) damn straight... but I think 160 is optimistic without the engine being dyno tuned and have a nice cam and probably some porting of the heads

C) if you do the crank, rods and pistons, and a cam to take advantage of it... you are liable to run lean with the L-Jet, I would go carbs... you could "probably" do it with L-Jet, but you wouldn't be getting the most out of the engine...


Jake and many other know FAR, FAR, FAR more than me... but this is my opinion...

He did say switch to Webers, so it won't have the L-Jet on it anymore.

160hp is very probably possible with a 2056 (what you'd get with a 2.0 crank and 96mm barrels), but only with a cam that requires you to rev the engine to 7000rpm or so to get that power. You'll have much less low-end power, and it will probably be a much less enjoyable street engine.

Jake's own data shows he gets 140-150hp with a 2270 (78mm crank and 96mm barrels), webers, and a cam tuned for good low-end.

With a good street cam, I'd venture you'd see something more like 125hp with the engine build being discussed. Still a very worthwhile thing to do.

If you stuck with the L-Jet, you'd be restricted in what cam you could run, and you'd be limited to something close to 110hp.

160 is IMPOSSIBLE with that combo!

thanks for the info guys, but next on my list before I redo the bottom end, is to get some wheels. Drove my car to work today (I work part-time at a tire store), took my wheels off and guess what? 4" wide Karmann Ghia wheels. Well this isnt going to work... Jake, i will keep in touch, hopefully the bottom end and cam rebuild will be on the agenda soon.

jake, how much for the parts to turn my 1.8 into a 2270 'C' motor? Would i be better off to just send you my engine and have you guys put all the goodies in?

Also do you run weber 44's or 48's on your 'C' engines?
