Alright, last topic I got some heat for being a lil vague. Lets try again, 94 Accord f22b1 4dr. I absolutely REFUSE to part with the big block. (150K, head+block clean as a whistle)

Goals: At least a mid 14 sec QM, shootin to smoke a gtp w/stage 2 sc pulley & thrasher intake. (Roughly 225-250 wheel horse, as much torque as possible.)

Budget: $1000-$2500 (I Kno, I Kno, but im not doin crazy internals)

I like the idea of goin n/a w/ nitrous but I cant yank the motor to do internals.
Long story short, is a 14.5 possible with $2500 in bolt-ons? Im willing to do the head but i CANNOT pull the engine yet. Im thinkin APEX'I ws2 cat-back w/ megan race header, bisi stage 2 cam & gear with bisi springs & either a skunk 2 intake or a fully custom mani. If theres any cash left i'll spring for a TB and get everything port 'n' polished. But thats just me...

 

Don't forget to put money aside for tuning. That is the most important part of a build and most people forget about it. There is no use in adding a stage 2 cam, valve train, intake and exhaust if you can't tune it to get the most out of it.

With your goals I would consider a mild boost setup. If you shop around you can piece together a pretty decent setup for less money than it will cost you to get 250whp N/A. The stock bottom end can handle 250-300 pretty easily as long as you have a healthy bottom end (good compression) to start off with.

Good luck

 

I was hoping for your input ghost. Compression is lovely across the board, But is a re-tune really necessary for IHE+cam? I was expecting 25-40 horse MAX from bolt-ons, and relying on nitrous for the rest. Obviously n20 would require a re-tune but if you say boost than boost it is. However i've heard vtec isn't very friendly to boost on the f22's. Anyone care to elaborate?

 

If you get an aftermarket VTEC cam that has some R&D behind it there shouldn't be any issues. I do remember hearing that some of the initial VTEC turbo cams were hit and miss. However, there are a few v2 VTEC turbo cams that I have been reading good results about lately. That's the difference between companies that do real R&D and those that go with using cut and dry numbers across the board for all their parts.

As for the tuning requirements. I would day that if you are adding bolt-ons, ie cam header & exhaust, that will put you into the 40 extra Hp you would definitely benefit from a bit of fine tuning. Will it run on a stock ECU........ I'm not 100% sure, I do know that you probably won't be getting the most out of your parts though.

 

Ghost has it right. A basic boost setup will definitely put you around your goals and you can do it without tearing open the engine (if it is in good shape of course).

And to be clear, by "basic" I mean just the essential turbo stuff that you will find in any turbo DIY. As Ghost said, good tuning will make all the difference in how well the car performs so try not to skimp on it.

You won't really get near 25 hp on just bolt-ons and you won't need a retune unless you add a cam. With the cam and a proper tune you will be in the ballpark of what you were expecting. Nitrous would work for you, but with your goals I'd say just go boost.

With nitrous you might still come up a bit short, where as with boost you will make your goal easily and possibly surpass it depending on parts used.

Also what Ghost says concerning the VTEC cams is accurate. If you search you can find some comparisons and tests.

 

Bisimoto makes some good turbo cams.

 

you wont even need turbo cams for your goals...

A turbo setup with quality parts will easily put you over 200hp/200lbft which will give you the times you want..

 

You'll ruin your motor in no time with a custom cam that throws your AFR off.

 

Even with a proper tune it would throw his AFR's off an ruin the motor? Appreciate your info on this as i may do a turbo setup in the upcoming year.

 

No with a proper tune you will be fine.

I think nus was referring to the OP's question about requiring a tune after a cam swap.

IIRC there are some stage 1 cams that can be run with a stock ECU. However, you probably won't get 100% out of them. Most of the cams with larger power gains & higher lift require engine management / Tuning.
