putting vtec head onto a D15 block

[Jmunk]

There is no replacemnet for displacement. That says it all. You want more power than you need for displacement.

[Bleebdat]

I never realized that a 1.6vtec had more displacement than a mini-me.....do you even know what you are saying anymore?

[Jmunk]

A 1.6 Vtec has more displacement than and mini-me swap assuming that your using the D15 block. In order to get the same displacement as the 1.6 Vtec you would need to swap pistons the 1.6 pistons into the D15 block. As far as do i know what i am talking about i think that i know enough to comment on this. I've done enough swaps and rebuilds. In my opnion you would benefit much more from the full 1.6 Vtec motor swap. I have seen people with the mini-me swap and they had a heck of a time with getting the correct fuel mixture. It will run decent but most of the time the motor will run a bit lean without a good deal of tuning. If your going to do the head swap please do it right and don't be cheap and half ass it. You do the head swap and bring it to me and i'll get my friends CRX with the full D16y8 motor and we can see who wins. It's your money and spend it how you wand but in the long run to do it right you will be at the same cost of what the full motor would have cost you. If you do the head swap than while you got the head off you mise well take it and have it shaved like thirty-seconds, that'll give you a little boost in compression.

Bleebdat,

if u have a dx u have to convert to mpfi, si and i believe hf dont.

The HF will have the correct wiring but you will not want to use the HF intake manifold and throttle body. it is TINY compared to one off an Si. I laughed when i pulled the toothpick of an intake hose off of the quarter sized throttle body on my HF CRX heh.

You'll want to swap the intakes if it is going in an HF

i got a 89 crx sir two door

got dc headers stright piped intake and racing plug wires

i am going to race my friend on new years and whoever wins gets 50 bucks lol

what is the best thing to do to my car to make it fast =]]]

You could try a few things..

1. Get a twin charge setup, running a turbo and a JRSC.
2. Add to that about 300 HP worth of stick-on JDM'ness.
3. Don't bring up old threads.
4. Boost your compression to some ridiculous number only acheivable on paper and in Dyno programs, like 32:1.
5. Add enough NOS "to blow yaself up. Period."
6. Stop bringing up old threads for stupid shit... or for anything.
7. Watch The Fast and the Furious again.
8. Get ready to prove what you claim. If you have an Si-R, post pics.
9. Limit your posting to threads that aren't considered "decayed" b/c they're so old.
10. Go race on the most public street you can think of, preferably in front of the local police station. When you get caught, tell 'em DropZone sent you.
11. Lose your ride to public auction, where I will get notified of it's sale, buy it, and part it out.
12. Last but not least, don't bring up old threads anymore.

Yep, that should pretty much cover it.

Oh, and read the damn FAQ and the forum guidelines... the mods didn't write them for their health.

[FrodoGT]

Wow. For a sec I almost thought you were giving real advice.

[Christ]

C'mon now... be realistic.. when's the last time you ever saw me give REAL ADVICE? lol.

Seriously. I actually tried to make it look like there was real information in that babbling post of random nonsense.

My personal favorite is tip #2.

[FrodoGT]

Got me all worked up, anything about twin charging and im all about bashing the "mythical" setup back down to reality.

[Christ]

Well, as far as that, it's not *mythical*. Nissan and Toyota have both used it, as has Lotus' race team, using Toyota engines.

I'll have to look it up again, but I'm pretty sure there are production cars that have twin charged setups on them on the street. Maybe not in the US, but fuck, the US has nothing compared to other countries when it comes to performance imports... Shit, even most Domestics sent their better shit to other markets... like the Ford RS200 (Escort). C'mon.. that would have been sweet as shit.

[FrodoGT]

Oh I know for sure that they have been used, and that they have been in production. I just say mythical because most people think its some new and fantastic technology that will make gobs and gobs of power.. when it isnt, and it wont, not like people think anyway.

[Christ]

Duly Agreed. It does, however, pose an interesting basis for making power on small displacement engines. Wayyyy off topic.

Locked for the obvious.
