personaly I would prefere a motor that was NA, when I race thats generaly the car I go with.
as far as rules and class, I have no idea, the owner is checking with the stewerts to see what they say. and they may change thier minds after his first couple races. it would be nice if they had a spec 350z class.
eitherway we are going to end up prepping the car for the track, cage ect. and then he has his own guys that will work on it during the season.

god i love this thread.
but don't you think a stock na motor making 250whp, which comes in the car, would be far cheaper and FAR more reliable than having a ten year old sr20, running 14psi and costing 5k to make 250whp??? na motors are going to be alot more reliable road racing, as well as being alot better in the texas heat.
and just out of curiosity, what class would you put yourself in for road racing with a motorswap? if your going to reclass your car over a motorswap, it better be a damn good one, that is completely necessary. racing has alot to do with being in the right class, with the right car.
this thread is the sillyness.

you know, with your logic the best bet would be a ka24e.
how your "shop" stays in business or finds peopel stupid enough to let you touch their cars should win you some kind of award.

well the owner is still waiting on permission from the stewert to use the SR20. you cant really modify the motor to much other then changing gaskets, and he cant run the haltech so either way it will be a factory ecu, so there is not a whole lot of tuning you are allowed to do.
the VQ motor dynos around 245, with an intake and an open exhust I am thinking 260whp
with the SR 225 is what we get out of s13 motor, with a 3 inch exhaust, intake and FMIC, (not sure we can run an FMIC, swaped 240's can) waiting to see what the stewert says.
there is also the option of going with the S15 motor, though the initial cost would be a bit more, he would have more power.
as for blowing the motors, each race is 6 hours long, most of the races are run in temps above 100 (its texas) I honestly cant say how many he will go through, he has done it before and he is paying for it.

and from what you said before the sr would end up being $800 cheaper but 100hp less.i would love to find a part that adds 100hp for only $800.that would be awesome.ad i think everyone would have that part

when u say he plans on replacing the motor 3-4 times a year.WHY? cause they are bored/? that is absolutely retarded.how about instead of replacing the motor that many times,u build a good motor, tune it well.and not have to replace it even once.i find it stupid that someone would plan on replacing the motor 3-4 times, especially such a relatively new motor.

the owner is an idiot if hes going through 3-4 motors a year, VQs are cheap now anyways, hes wasting his money just to build a kitchy car. no matter how you slice it.
but I think you should do it for th $$$$

this has nothing to do with power, this is a track car. the owner/driver is planning on replacing the motor 3-4 times a year. 4 SR motors is much cheaper then 4 VQ motors (at least at the present) and replacing an SR is faster then replacing a VQ, if you pop a motor during qualifying, you can swap motors intime for the race

if you need to do something different/ricertastic/to increase your e-rep on drifting forums, at least do something cool that hasnt been done back in 200longtime ago. put a ls1 in it.

spend $5k to have less power, smaller powerband, a big car with no torque, crappier tranny with one less gear, a harder time finding parts every time something breaks, its completly fornicating stupid in 2007, no matter how awesome your "performance shop" thinks it is.
i think the sheer stupidity of this thread is best illustrated by the fact you posted this on drifting.com's tech forum, as this has been the most active topic in a longtime just due to the sheer idiocy being displayed in this thread.
summary
spending 5k to have a shittier motor than the vq because you dont want to spend money on the vq to have 2x the power = stupid.

I believe chris forsberg was still working at signal auto when he did his sr20 conversion... 2 years before the chromalusion car...

Hope some visuals help.
Edit: Signal used an SR20 because from what I understand its lighter than a VQ and easier to modify. They used it for time attack so if you are going to strip out the inside of the car to make it club racer than I guess you want it to be as light as possible.Last edited by NismoSigma; 12-30-2006, 11:25 AM.
