Default 89 formula 305 vs. 99 civic si

Well i knew this car was slow but i didnt know it was this slow. This newer civic comes up and throws a rev at me i thought oh this is gonna be easy. Well we take off and to my suprise he was dead even with me he passes me at about 50 and procedes to put a car on me . We stop at the next light and i asked him what he has got on it all he said he had was intake header and catback. he then proceded to say i bet u didnt think i was gonna beat u? oh and there is more he told me i should get a honda. LMAO when i told him ive got a 2001 ws6 and a 97 ss waiting for me at home

more like the 4 inch bore of ur 5.7 makes the difference. if the 305 had a 4in bore it would be nice. the tiny *** 3.7 or less i forget bore inhibits the engine from making big power.

You only have 10 more horsepower but 800 more pounds of steel.

Outcome as expected.

Put some bolt ons to it.

You can get a FULL exhuast (headers back) for like $250. Dirt cheap. Get an intake upgrade and it'd at least be respectible. And it would SMOKE a n/a civic.

uh....what engine do you have? is it the Lb9 or L03. If you have the L03, you deserved to lose and should be grateful it wasn't worse. Those things are SLOW, but yea, bolt on will help out anything, especially a TBI motor if that is, in fact, what you have.

Yeah, did you ask if it was a TPI or a TBI?

Also, a 350 swap from a truck wouldn't be a bad idea either. I got a full engine pan-to-intake w/ 60k miles for $150!

I would have thought that the 305 TPI M5 TAs were more powerful than that. What were they rated at in 89? My sister has an 87 IROC 305 TPI bone stock. Its rated at 215 hp and 275 lb/ft torque. I have driven it several times and I KNOW it would not lose to a catback civic.

Good news is you still have an LT1 and an LS1

Yeah, I HIGHLY doubt he would have lost to a civic if he had any kind of TPI engine....my bet is he has the infamous 170hp L03. They are the devil because they have a nice torquey feel down low and give the driver the false appearance of speed. 0-60 in like 8 seconds....0-100 in about 25. and if it's stock...just that much slower.

ive got na LO3 in my firebird convertible but i can honestly say this thing was made for reliablilty reasons...people today have the wrong aspect of TBI and what plans GM had for it...1st off GM put the worst heads "swirl port" to be exact they flow like crap. 2nd is the cam...gm put a i believe 336 lift on the stock LO3 cam so how much air can this engine flow? next is the exhaust manifold more restricitive then a virgin and lastly is the crappy PCM that all this has to function with....of course GM at the time had 2 other motors making "big power" which was the tuned port motors. Now if GM's 305tpi with better cam, better heads, less restricitive exhaust and better design all together lost to a shitty designed TBI motor....how would this look on paper? figure it out LO3 crappy cam, low flow heads, restricive exhaust, barely tuneable PCM made 170hp and 255tq.....compared to 305TPI(LB9) 215hp 270tq better cam, better heads, better manifolds and better fuel managment system all together....now if the TBI motor had all these better options who do u think will win the 1/4 race something to think about huh?

I would guess he is running the 170 hp version, and the highest civic I can think of was rated at 160.
