ok...well first off im new to this board and wanted to say hi. aiight well at this time i have a 95 del sol. i have a plan that i wanted to run by you guys and school me on the preludes. ok well i want to get a 93 prelude and throw in a jdm h22a...right after that is complete i want to throw a turbo in there. now i have run this idea across a few people and they seem to ask why do that to a prelude because they are heavy and with those 2 huge mods i probably wount even be able to break into the 13's??? is this true??? i want to get the motor and turbo before i start throwing on a body kit and things like that. what im asking is help me out with all the prelude knowledge you can spare......should i go supercharger or turbo??? thank you in advance for all help and i look forward into switching over to the prelude side!!!

 

They're right. Do it correctly, the H22A and a turbo, tune it with all the goodies and you won't be in the 13's...

You'll be in the 12's

I hate ignorant s who think that because the Prelude is heavy that it can't be fast. That's why the H22A has TORQUE.

 

You might want to do a little more research before "throwing in" a turbo. (If it was that easy everyone would have one.) If you are only going for 1/4 mile or 0-60 (low end acceleration) then IMO a supercharger would be the better take. This takes care or lag time, and is easier to put on (you could go without an intercoler with a supercharger), however is much less efficient. If you drive your car every day, especially in the winter, go with the turbo.

 

and whats wrong with the USDM H22? I think that one of the reasons the JDM H22 make more power than their US counterparts is:

1-higher compression ratio
2-slightly aggresive cams? (Type S?)
3-higher octane fuel available in Japan.
4-do Japanese cars have Catalytic Converters? (I cant remember)
anyone fell free to add anything I left out.

EDIT: another thing what does your budget look like? how much will you be able to spend on this "project"?

If you plan on getting into the 12's or 13's you'll have to upgrade your internals.
-there goes your high comp. ratio
-there goes your cams (to much overlap and blowby on Type S cams?)
-we dont have 100+ octane available at the corner gas station do we?
-your car will more than likely have a catalytic convertor.

anyone feel free to add or correct anything.

with a JDM swap and block buildup your looking at what $2000-$3000 plus the engine and swap cost? then there is your turbo and all related hardware. I'll let you do the math.

On the question of whether you should go turbo or SC there is a very simple answer. Nobody makes a supercharger for the 4G prelude. I've only seen one JRSC fitted between the block and firewall and it involved custom fabrication of the firewall. Turbo would be the easiest option, but some people have been having trouble making good horsepower. It has been done by JG engine dynamics though and they made some very nice numbers(Using stock USDM cams). Personally, I'm going high compression and nitrous for drivability and expense issues. If I had to choose between SC and turbo, turbo all the way.
Rant: Whoever said you wouldn't hit 13's is an uninformed bastard. Wutangben is hitting 13s with a 55 of nitrous and bolt ons.

 

you'd be better off buying a prelude with an h23 motor in it. it's probably cheaper, and a better motor to turbo than the vtec h22's.

ps does jgluder really have 13 thousand posts?

Yes. He is/was the ultimate PW. Just not in the tech forums.

 

Wutangben,

altought the H23 SI is easier to tune and probably cheaper, the H22 VTEC willbe a little harder to tune but it will give you more horespower at a compareable boost. I'm talking like 10+ PSI of boost, I've seen dyno sheets to prove it.

i dont think youre right, ill post an explanation to back my statement up when i can though, i gotta get to bed.

peace

 

H22A1's have a lot of overlap. Turbo's hate a lot of overlap. N/A loves it.

If you go H22A1, get some cams, and boost the **** out of it. Then call me when you blow up.

Yes, I have 13,000+ posts. A lot of which are from the kill forum, but a lot of it is form this forum.

 

ok my budget is going to be around 10,000 dollars. that is with the expense of the car. right now i am looking at getting this 93 preude for about 3500. the reason why it is so low is because of engine problems (like the engine isnt all together..lol) anyways that will bring my budget down to around 6500 dollars.....i figure one of my boys did a d16 to jdm b16 obd1 to obd2 swap so he can help me on the and that will save me engine installation fees. thank you all for your feedback to this point and i look forward to hearing more responses.

 

Since you're on a $10,000 budget go with the H23A, boost it, get a good suspension(At least Koni yellow and Eibachs) and then go from there. You'd still need to resleeve the block and drop in forged pistons and rods, before you can really crank the boost up, but a $10,000 boosted H23a will make quick work of a $10,000 NA H22a.

 

where can i find a h23 engine??? and why are those better for boost than a jdm h22??

 

Lower compression, more displacement, less overlap. Basically people don't have problems boosting H23As, but they do have problems boosting H22As. . Try HASport.com for an H23a

 

same here, I dont want to say you're wrong just yet. I need to find out exactly where I heard/saw the dyno graph of a Turbo Lude SI. If I cant find it I'll try to recollect what I read/saw about the Turbo Lude Si's.

I dont' know about CA but just for curiosity sake, over here on the Eastcoast there are 2 lines of gas stations that sell 110 octane out of the pump

 

if you go with a h22a then go with the type S it has more power 220hp if you are putting this into a Del Sol then i would still go with a b16A2 then turbo that. you would more happy.

 

if your gonna turbo then your gonna want to stay with a obd1 Jdmhondaparts.com has h22a for $2300 for everything you need to do a swap
