Today was learning experience ..... I woke and decided to do a 3.5 swap today? Now who wakes and just says Ill do a 3.5 swap to day..me I was board! Besides the point just wanted to say that not only am I going to have a 300 hp power legend Im going to be the first to have a 300 hp 3.2 and 300 hp 3.5 in the same legend! But wait theres more I have have pictures for you yea i said you skeptical people!

Are you saying your done with the 3.2? Or planning on using both engines?

-Ed

Either way, if you do this, I'm definately driving up to see it.

I must say it is a good start but your not done.

well I figure that its just one more thing I can claim I did to go along with my first ever gs conversion and my first ever 300 hp na 3.2

Sorry bentley along with all the other 3.5 cheerleaders. But ignorance is evident amongst you all.

Have you not realized that the fastest legend as of now is Erics 3.2. I know the weather was in his favor, and he wasn't running with full interior but the weight of his car compared to dv8's is pretty close in race form.

Keep in mind, the top end of the type 2 is better than the 3.5 hence the reason dv8's has the same hp output and is running a type2/3.5 hybrid. It will alway's have more torque, we all know that. But, without the type 2 top end, the high rpm hp will not be there and the blend of hp/tq as sr5 stated will not be as uniform.

Not only does Eric have less displacement, but he also has a few mods of lesser quality than dv8's 3.5 hybrid.
Dv8's 3.5/ 233.7 Whp, 229.0 Tq : custom headers, aem ems, injectors, short shifter. I'm not sure of the port/polish quality of both, so I cannot contest that. But I'm sure there are differences, for better or worse, I'm not sure.
Eric's 3.2/ 230.4 Whp, 203.9 Tq: Obx headers, Sr5 chip/aem safc, stock shifter, stock injectors,
Sorry, unpnorthacme, but not everyone is building a racecar. The difference in the power curve of a stock 3.5, especiallly a semi-hybrid type II, leads to a very enjoyable daily driver. My old-time chevy head boss compared it to swapping in a small block 350. In fact, just as many people that are swapping for performance enhancements are swapping for the lower mileage and better perceived reliability of the 3.5.

If you are building an all out high revving race, car then yes the 3.2 is a much better motor simply because of the high RPM sustainability of the block and heads.

Lets not start this argument unless there is something to argue about. Your criticisms are not constructive at this point because theres only two 3.5 dynos on this board to compare to, DV8 and Mike Diaz. In my opinion, DV8 is on another plane making it hard to compare to anyone elses setup, and (sorry Mike :hide:) Mike's dyno is kind of crappy. I'm opening myself up here because I was supposed to dyno my car but shit happens and I didn't get around to it before I sold it, what can I say other than I'm sorry?

I totally agree with you matt. If you're not building it for racing, than yes the 3.5 is the way to go.

Fun to drive with the extra torque along with better gas mileage using the low rpm torque to cart around town, especially with a manual. And the reliability is another factor although I have never had a blown headgasket with any of my 3.2's.... 4 to be exact.

There aren't any arguments to be had on this topic. We are on the same page here it seems.

I was pointing this out to bently on dubs since he feels the need to talk shit about the 3.2 at every point possible since he is performing the 3.5 swap and thinks it is superior to the 3.2 in terms of power.

I am sure artillery was being sarcastic.

I say if you are swapping motors anyway then do the 3.5, it makes sense to do a real upgrade.

so yall are sayin that the hybrid 3.5 block with the 3.2 type II head is the best bang for performance so if that so how much would it be to build that minus having someone install it because that would be something i could do myself
o yea and man i wish my junk yards were givin motors away for under 500 they wanted like 2g for a regular non vtec integra motor i told em there out of their minds

All depends on the source you purchase from.

Junk yards:
3.5 motor $300-500
Type II heads & Cams: $150-200
Type II I.Manifold: $25-75
Head gaskets OEM: $200
I.Manifold gaskets OEM: $75
3.5/3.2 custom mount: $50-100 for the mount plus welding
Ecu, Reflashed by Telion $75 plus cost of ecu.
Timing belt/water pump: buy new. Ebay: $100-125
Spark plugs: $$ Depends on what you run.

Total $975-1,350 No labor charges.

Your understanding is correct but if you can swing it do it if not just go with the RL heads and TII intake manifold, cams (regrinds preferrably), TII springs (yes they work) and FPR. then your setup should ge solid throught "the curve." and run to a higher RPM without the stress that the RL engine alone experiences. And if there is any doubt about that find the video of my car running to 7200, there is no lag time and this was pre camgrind, and pre aluminum crank pulley :)

i dnt know what the big fuss is, its been said by almost everyone who has done the 3.5 swap that it is worth it so y are people just not accepting it, yea mayb you can rev the 3.2 higher but thats just more stress on parts and even more chances of something going wrong y not have the little more displacement to make up for having to beat the hell out of your motor redlining it
 
#50 ·
Because it's not beating the hell out of it. That motor is designed for higher revs and will take it all year long along with the next year and the next.

I accept that it's worth it for a DD, but not as a better alternative for a racing set up since half the motor would be type II anyway.

This topic is beat to the fullest. I'm out.

ALL MOTA GUY!
Ahguy, dude a u like da wickedest bub day'a O sumptin?
Well, I put a 2jz in the trunk, with a turbo'd suppa chaaaged k20 on the roof cause thats like the best spot evva, and a rb26 under the hood with max dufalattas, dual hollypoppa's, and freekin flinstone in the passenger seat.

Do you know what that makes.... Not Haaaus Powwa. Yeeeah, ya know, a... ya know, uuuhm, hmmmm, oh yeah. Well, I couldn't tell you, I'd have to kill you.

haha i knew those dyno graphs would pop up sooner then later :) why dont you just go hit up the track again before you go FI that way you'll have some official times. Ill most likely want to join in on the fun too, we could have another drag day :yumyum:
 
#61 ·
Wouldnt do me any good. Im less powerful then my setup in June 07' at this point. Wider tires all around, a BBK, aluminum crank pulley and a custom I. manifold built for F/I. The confirmed true + gain would be the crank pulley-confirmed by the way 1st gear rips othewise I dont know what it does to my mid and topend. Car feels too much like before the i. manifold which was a bit less powerful since the wider tires and BBK done in August+. Add to that it needs to be re-tuned(very rich), and I would have to feather a 1000rpm launch on street tires, a drag day with limited runs would be a waste of my time. Isolated street race on a private road offers dead stop runs, rolling runs and topend runs all with something to compare to.
Otherwise a dyno in April will sufice. I need to order me up the new slicks.

hmm i might be down, im just about to re-due my exhaust with mandrel bent sst and tig welds cuz you already know my exhaust is ghetto rigged at the moment haha
