For a 3000lb anything with wheels, you'll need roughly 300hp+ to put down low 13's. Some engine builders have made that kinda power with these motors N/A, but they are in no way streetable...not unless you have DEEEEP pockets.

). That's actually good to hear, that means my Rocco should be faster then I thought.

great art., but when it comes to compression u forgot 2 ways of increaseing it. #1. a thinner head gasket. #2. high compression valves, these are made by skunk2 and are flat at the bottom instead of dished like normal valves therefor reducing the size of the cc. i'm doing both of theese as we speak, as well as a shitload of head work, cant wait to get it back, its going to be fast!

I'm currently building my motor and compression should be around 11:5:1 before carbon build up. I had alot of headporting with ferea valves and some type S pistons installed. I have yet to tackle the fuel upgrades. I am considering some mitsubsishi eclipse 440 injectors. I'm not sure if they will fit in without modification but I know they are peak and hold and can be installed on B series motors.
Is anyone using these injectors?
Also, who has modified their auto tensioner to work with a milled head?

I recommend you going with 370 cc injectors. I had 11.0 compression pistons and my head was milled 50th about 3 1/2 years ago. I made 210 to the wheels with that setup. My injectors were not maxed out. I never had to modify my auto tensioner at all. I never had any problems and you shouldn't either.

Re: A few things to think about when going N/A...... (b18cURmama)
well n/a in a prelude is not going to work well b/c well the prelude weighs about 3000 pund and it slow. the only good thing would be to turbo that beast

Ludes are better looking than tegs no doubt. Ludes are not slow, bottom line is that they dont break out of the 13's very easily. If you can be happy with 13's, the Lude is fine. Just with 75shots of nitrous you are into the 13's.

The same goes for exhaust, if you have TOO large an exhaust, you won't have enough backpressure to help pull the other gasses out of the combustion chamber, and you'll actually lose power.
I disagree.
Backpressure will always hurt performance and will never enhance it.
Proper exhaust gas scavenging/ maintaining exhaust gas velocity is what 2.5" piping as opposed to 3" is all about.....
I have even heard that the tendency to go with 3" piping for road race cars is becoming more prevalent now... But maybe that's just a trend or rumor.....

I wanted to ask you a question...I have a 97 prelude, stock 
, and I wanted to put a turbo in it. What do you think is the best one? I was looking at greddy. Also other than exhuast what else would I need to change???
Thanks

Let's stick to naturally aspirated...
Ok next N/A question, if I was looking to do an OBDII to OBDI swap...what is the best option:
1) JDM OBDI ECU
2) SR-V/VTEC OBDI ECU
3) GS-R ECU
I've seen the results on ImportReview for the GS-R ECU, but I don't think I could take that loss at the low-mid range for the top end gain.
So in terms of JDM vs. USDM OBDI ECU's
A) Advantages of JDM ECU? (hmm advanced timinghat potential problems/stuff to buy am I facing with a JDM ECU? I am thinking the fuel maps will be for a higher compression and higher octane....so I will be running lean?
If anyone knows, to what extent can I adjust this with the V-AFC? Will a FPR be necessary as well?
I'm think this is what I should do next before I do any more bolt-ons cause it seems like a waste of money if they're going to be detuned. And I can chip the JDM ECU in the future...

Regular OBDI ECU, then have it programmed by ImportReview, or Prospeed (who did mine) and you can get increased redline, and advanced timing and fuel curves.

If you're at the track, running 8k all day, then you want an exhaust that will give you peak HP at 8.5k. If you're drag racing, going from 0-110, or driving on the street, then losing power up until 6,500 isn't a good idea.

Re: A few things to think about when going N/A...... (cockyboi)
you're going to have trouble finding anyone who'll touch that ECU. LOL.
My suggestion is to get in contact with Jeff at: http://www.importbuilders.com
see what he recomends. I trust his opinion on most anything.
