Most Powerful Engine???

What is the most powerful engine I can possibley get for my '93 Prelude?! I'm assuming it's some sort of VTEC. I heard it doesn't even have to be an engine from a prelude - but other honda engines can work in my prelude as well? Also, anyone know of any turbos or superchargers that would be worth the money? I think it would be sweet as hell to have my little lude pushing 300 or 400+ horse eventually (without nos). Thanks for any info!

i think u can put this in:

Honda HF118 Turbofan Engine (1,670lb thrust engine :thumbsup: )

we all know how versitile honda engines are :D

oh yeah...when refering to nitrous oxide...please use n2o or nitrous...not NOS unless ur refering to Nitrous Oxide Systems

RB26DETT .... that's the motor you want

That's a nissan engine - would it actually work in my Prelude??? 285 HP does sound nice... unfortunatly this one says it's both rwd and awd... no front wheel. Just out of curiousity - how much would it cost to turn my fwd car into an awd car? A rediculous amount? Here's one of those engine's on ebay:

awd...hmmm...i know for a 4th gen civic itz pretty easy...but for a prelude...i'm thinkin very expensive and not very easy...

you can make a 4th gen civic AWD, can you please elaborate? I'm actually in the market for a civic and if i could make would AWD it would be a no brainer which gen to buy.

You can make any car AWD. However, it doesn't work well if you are actually serious about straightline performance. You basically take the differential from a RWD car (if you have a FWD one)that has a similar rear and transplant it onto the current car. It takes alot of fabrication and wielding, along with experience with suspension design and bracket geometry. If it's not done exactly right, you will have one seriously fucked up car.

Lots of people talk about AWD conversions and how they're going to do it, but very few people do due to the cost and expertise required. That, and Civics are crap. If you want AWD, get an Eclipse GSX.

To answer your question, the most powerful engine for a Prelude is the Type-S and Type SiR h22a, which have a 220hp h22a block. This is a JDM block that is only available through a relatively easy conversion. It is a 2.2L DOHC inline four that features variable valve timing. Very nice.

can use the wagovan drivetrain...which i hear is not very strond and can't handle a lot of power...or use a crv drivetrain

Where can you find one of these H22's to buy. i'm still lookin' for one to buy. Found one for 1350 w/ everything but the ECU and the tranny. But the jdm H series bolts right on the F series tranny so that's not a prob. can get chipped ECU's for something around 100 bucks which is cheaper than a lot of stock p13's i've seen.

how about one of those Moroso vtech crate motors, i believe its made by moroso. Its called the beast i think, and its a NA running about 250hp at the crank.

I have seen those around. I think they just have some head work done combined with stronger pistons and rods. One can duplicate the same thing with a standard H22.

and how much would a "beast" cost?

if you have to ask you cant afford it :smile:

Alright, well, I'm probably going to get an H22A1 engine then. I'm also going to get turbo put on afterward - this one, specifically, if I can. I emailed the guy and he told me with the stage 2, which was $90 added on to the price of the turbo, my power would total to 450 hp. Sounds good to me! My little lude with 450 horse, ha. Here's the turbo on ebay, tell me if you think it's a horrid idea, or if it sounds like it'd work alright: http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&item=2482749827
I currently have a 2.3 Si with all wheel stearing. This engine should work out okay with my car right? I'm sure it can't be worse than trying to put that nissan engine in it! :p

Well, I don't know too much about this whole topic, but the body of the lude is made to withstand a certain amount of specifications. Wouldn't putting all that horsepower on the body eventually wear it out? I mean thats a shit load of horsepower :grinyes: and it sounds just sooo good, but I dunno... it just seems like an awful lot for it.

:22yikes: wtf? ive thought about boosting my lude before but from what i know, h22's r spose to be very hard to boost and are turbo un-friendly bc of high comp, thin cylinder walls, weak internals, etc... this cant be right, im guessing theres alot more you'd have to do before jsut buying this kit and slapping it on onto a stock h22a1. anyone else have thoughts on this kit bc it seems to0 easy and too good to be true.

i heard just the opposite - cuz of the closed deck design - or is that just the JDM H22A.... anyone have any idea?

The promises on the site are true. However, it's not what you think. The *turbo* can support that much horsepower. That means around there is the maximum psi it can can go before it's just blowing out hot air. It doesn't necessarily mean your car will be at that stage.

A Prelude can be turbocharged up to 7 psi (6 recommended) safely. At our compression, that would mean an extra +60 horses. But certainly not enough to get over the 300hp threshold without some work to the engine.

so aces, your saying that with this kit alone, i mean just this kit nothing else, that our lude can safely run up to 7 psi (daily) with completely stock internals and eventually run higher boost with built internals??? bc this seems very very cheap for a turbo, but incredibly promising.

I would say 6psi, but yes. A turbo at that kind of pressure would cause quicker wear on the engine, but not to the point of being overtly detrimental. In the future, once you get stronger pistons and rods, the h22a can more or less handle +300hp. That kit is missing a few rather expensive parts: intercooler, FMU, injectors. But I should say that if you have enough turbo expertise for installation and component gathering, it is a good deal.

Yeah, someone told me they thought that stuff probably needs reinforced for that kinda power. They didn't know what exactly, they just heard that stuff like that usually needs reinforcements on certain things. Anyone know what all there is to be reinforced? Damn, I was hoping for that 450 horsepower! hehe

yeah......i can see my prelude cruising down the street...then ERRRRNG pshhhhhhhht. how much u guys think i could find an intercooler and FMU on ebay???

Well back to the original turbo question...www.turbokits.com has some good stuff. I actually bought my car from one of the guys that runs the site, he's an honest guy and really knows his stuff, he offers a few different turbos for 4th and 5th gen preludes, as well as other cars.

Okay, I checked it out, now, could someone explain a couple of these things to me please? I'm kind of car illiterate :p

Boost: 8 PSI
HP Gain: 75-100 HP (safely on stock engine)
Turbo Efficiency: 400HP

Alright, it says boost, 8 psi... what exactly IS 'boost', and is 8 psi a lot???
It says HP Gain is 75-100 HP, but turbo efficiency is 400HP??? If the gain is only, then what's this 400HP turbo efficiency stuff it's talkin' about? Thanks for any info ;)

PSI is the acronym for Pounds per Square Inch. also knowns as boost. it's a measure of charged air created by the turbocharger or supercharger. 8psi is plenty for honda motors. but with the right equipment, you can run 10 to 16 psi. there are cars that can run upwards of 25 to 30psi. turbos can be adjusted to generate different amounts of boost, hence different hp gains.

read up on this site. has some useful info

Absolutely awesome article. Thanks man - I skimmed it, and I'm going to read the whole thing later when I'm not busy :) . Sounds VERY informative

:werd:

speaking of boosted lude engines, what about the jdm f22b DOHC, it has the same hp and tq numbers as a h23, but has 8.8:1 compression and iron sleeves.

what be this compression stuff yee speakith of?

huh

i would assume that it handles boost better than an h23.
