okay, so i'm wondering what my best course of action is to get my car to the point where it will (easily) run a 12-second quarter-mile (if not better).

should I swap the engine out for _____________________?
should I rebuild my current SOHC vtec?
add NOS?
just do a turbo?
...or a combination of the above.

i want to go the best route for my car in the long-run and won't cost more than my annual salary

i've been meaning to talk to Modern about all this, but Christian's busy and stuff...so I thought I'd ask the other experts

i am also going to get a big brake kit (with slotted rotors) for the front and do a rear-brake conversion to full brakes. eventually i am going to do a custom interior, but no too much in the way of weight-reduction.

so whaddya think i should do about the engine? what are some other things that I will need to do for the car so I don't have a problem drag racing?

oh, and thanks in advance cuz i know next to jack about the internals of cars. I can change a tire & raise/lower my coilovers, but that's about it

DON'T DO NOS! I would either rebuild the engine or do a turbo. If you don't run NOS properly you can damage your engine. Plus with a turbo you always have the additional power and with NOS you only have the power when you shoot. Jared and I estimated the amount we would spend refilling a NOS bottle and realized that a turbo would be cheaper in the long run.

I'm not a pro but I agree that nitrous is much too pricey.

And I also think an engine build or swap would definitly be in the cards if you want to hit 12's in a honda.

My advice is know weither u are doing all motor or Forced induction because the pistons are diffrent and you have to know what you want to do before you build it

I Love these questions because I have already planned my eventual B18 monster. Fisrt Get rid of that SOHC and swap a B18c1. Send it out to a trusted machine shop to get it sleeved and bored to 2.0. Get some beefy rods crower or eagle will do. Get some Endyn pistons, Have the entire rotating assembly balanced and blue printed. As for the head get a P and P done Port match the Intake and Exhaust Ports. Three angle Valve job. As far as Cams and Valves you can get the aftermarket upgrades but the stockers will do just fine if going TURBO which you should for 12's. As for a turbo kit you have a ton of options. What I wanted to do was get a Greddy kit to start with. Get the turbo a P and P, ceramic coating, andÃ‚Â Add a front mount, Real engine management (Hondata, AEM....) and tune the crap out of the thing. Get a true 3" exhaust with high flow down pipe and please add a high flow cat. Get a high flow fuel pump, you may want better injectors too. As far as ignition goes you should go with NKG IK22 plugs, Some better wires and MSD has quite a nice set up you can go with. Do not take any short cuts. I could go on for ever but this is my plan not the best plan. I know B-town will have some changes or additions to what I have said. Have fun. After all of these mods a small shot of N2o would be a good kick in the pants. Be advised N2o will clog your cat and if used too much or if misused it will kill your built motor.

I think I have finally turned the corner of truly loving cars.

That engine description was turning me on a little.

WTF? Nitrous to pricey? This is a legit 75hp bolt on? With good internals plenty more. Sure you couldn't pull 12's w/N20 alone, but it's many times cheaper than F/I. It's going to have to be a solid run either way. N20 ~600-800$ for a pretty decent setup, where as Modern has probably already quoted ~2-3k for a turbo setup. Better internals are going to be needed to to 12's anyway. N20 will kill an engine just as easily as a poorly tuned F/I setup. It's all about knowing whats is happening in your motor. With all that said, Turbo is your best bet for 12's. Yes, N20 is only there at the push of a button. BUT the upside is that the motor is only subjected to 500+hp for short intervals & not very often. F/I always puts the extra strain on the rotating assembly. Generally to fill a N20 bottle it's ~$50. to spend 2K on N20 is 40 bottles. And I don't know of anyone who's gone through 20 bottles let alone 40 bottles of N20.

Just my .02$

It is better than porn I will tell you what.

overlord has some good ideas

you'll definitly get more power out of a DOHC VTEC than your SOHC. DOHC's average between 220-280whp with a regular T3/T4 turbo kit (meaning FMIC, BOV, external wastegate, log manifold, etc...) on the stock bottom end.

if you dont want to swap, it's still possible to run 12's with an SOHC, Cody is in the mid-high 11's right now with his non-vtec coupe and there are tons of 13-14 second SOHC's out there with stock bottom ends, its all in the tuning. i'd personally put more money into tuning than i would into parts. i got more power out of having my old, stock Si tuned for two hours by Cortney than i would had i spent $1,000+ on inake, header, exhaust, etc...

you wont get far in utah going all motor. i'd suggest doing the turbo thing, whether you decide to swap or not, and get a hondata S100. you'll have to convert your car to OBD-I, but its worth it if you have these kinds of goals. just run the turbo kit on the stock motor for a while and get it tuned as much as you possibly can. see how close you can get to your goal on the stock motor, then you'll know what you have to do to get into the 12's.

ZChick · « **Reply #9 on:** 08:48AM 09/28/2004 »

I know someone that kept his sohc and got good times but I think I would go with the dohc. I agreed with Overload- don't take any shortcuts.

utahteg · « **Reply #10 on:** 10:13AM 09/28/2004 »

I would avoid N2O like the plague...to do it right and safely you should build up the bottom end. If it were me, I would swap to a b18 of your choice, send it to be built - rods, pistons, sleeves (just as Corey said). Then get a reliable turbo -- precision makes some nice turbos with a lot of high hp potential...you need it to hit the 12's. You will need a complete 3" exhaust set up -- from the turbo all the way out. If you go with hondata get the s200b...then you have the capability to data log. You'll also need 500 cc injectors, fuel pump, fuel pressure regulator and fuel pressure gauge. After that have it tuned right and you'll easily be in the 12's if not better. Oh I would also get some lilght weight drag wheels and some slicks. As btown said you'll want to swap your ecu for a OBD-1, I would get a p72 -- vtec and knock sensor. Also, I almost forgot...get a light weight flywheel, and a good clutch.

Adrienne · « **Reply #11 on:** 11:26AM 09/28/2004 »

i don't take shortcuts when it comes to my car. if i'm going to spend the effort and money to upgrade my car, i'm going to do it right the first time

!

if this helps any, here's what I've done so far in the way of engine/performance:
Ingalls rear camber kit
GReddy SP2 cat-back exhaust
ACT HC5-XTSS Clutch set (Xtreme Duty Pressure Plate, organic disc - up to 270 ft/lbs torque)
ACT StreetLite Flywheel
Tein SuperStreet Coilovers

i am also going to get the StopTech BigBrake kit (slotted rotors) for the front and do a full brake conversion on the rear.

The original turbo setup I had planned for my car was:
GReddy TD04H turbo (integral wastegate, e-Manage, 4x 3100ccÃ‚Â injectors, cast-iron manifold, etc.)
GReddy 31V front-mount intercooler
GReddy Type S blow-off valve
GReddyÃ‚Â PRofec Boost Controller
dyno and tuning time

utahteg · « **Reply #12 on:** 11:36AM 09/28/2004 »

I would go with the type 24 intercooler...it's bigger and will work better if you're shooting for 12's. I would also sell the 310 cc injectors that come with the kit and upgrade. The 310's will max out around 220 whp...you'll need close to 275-300 whp depending on your setup and driving skills.

Adrienne · « **Reply #13 on:** 12:35PM 09/28/2004 »

i think the reason Christian chose the type 31 intercooler for me was because originally I was only shooting for ~200 WHP, but hey, I might was well shoot for 300 WHP, right?
what would you suggest i replace the injectors with?

utahteg · « **Reply #14 on:** 12:48PM 09/28/2004 »

I would shoot fot at least 300 whp. You can spend the same amount of money, but get more power...there's no reason to do it twice.
