I found a turbo for the b20 engine today for $2900. This is the website, http://ludespeed.com/products/prelud...npartlst.html. It has an intercooler and a bunch of parts come with it. Check it out please, is this too exspensive for a turbo? Would I be better off getting an h22 engine swap? Thanks

 

I'm surprised this is the first you're hearing of this kit. It has been around for a long time. The only problem is, I've yet to see a car run this kit without going up in smoke some time soon after. Chris from HondaPrelude.com had the most success, making 206WHP for at least a year before he had some kind of engine fire.

I would personally go with an H22 swap instead of the turbo B20. If you have the time and the knowledge to tune it perfectly, a turbo B20 can work. The problem is most people end up running lean and getting detonation, which will destroy the engine. With the H22, you wouldn't be sacrificing reliability in order to get a ton of power.

I read on his site that you can get a high flow fuel pump so it won't run lean. Then you can bump up the psi on your turbo. He said you can run it for about 100,000 miles without having any problems. Is this true?

 

How much would an H22 cost? Do I need a tranny and front end too?

 

Well... the thing about running lean. The prelude has no notion of "boost", and thus can't adjust its fuel maps according to boost pressure. You really need to upgrade the ECU and do a complete custom setup in order to get the fuel maps correct, and safely boost without risk of detonation. Also, did he give any examples of someone who has run 100k miles on that turbo?

The H22 swap is also a big pain, but at least it's a reliable N/A setup when it's done, and you probably have a newer motor with less miles. To do the swap, you need to replace the entire drivetrain, basically. Engine, tranny, motor mounts, axles, etc.

i go with the turbo. cuz you can boost!!!

 

:slap:

 

Do they have new ECUs for the b20? Engine swap sounds like allot of money and time to me!

 

Honestly, if you drive daily, I think the H22 swap would be more reliable... that's just my opinion.

 

Thanks for the help. This is my track car so I have a daily driver, I'm just hesitant to put that much money into an engine, so the engine swap sounds more economical, and the H22 has allot more mods available.
