What can i expect from the sr20ve and sr16ve N1's performance with all bolt-on? Basically doing all-motor. I may think about sacrificing my BB into one of them depending on the potential of these engine..... My buddy said the BB have more potential and he'd rather stick with the DET. What bout you guys what do you think....

Thanks,

mike

If you are sticking with the stock T25 turbo on the BB DET, then I believe that the ETs would be fairly close. I would give the overall WHP edge to the DET, but the VE would make more power at the top of the RPM band. Andreas mentioned that even though NA engines can make less power than a Turbo motor, that their powerbands are a little wider, and they can use their power more effeciently. A VE with, Intake, Cams, Header, Exhaust, Pullies, ECU and some weight removed (ie Spare and Jack) could probably pull some low 13 quarter mile times with the right sized slicks. I think that if you pushed the limits of a T25, and kept 370cc injectors, and stock MAF, but had a 3 inch exhaust, with a nice FMIC, and lots of boost. You would break into the 12s with slicks.

whowww, Sounds like I'm getting both, hopefully i could get the other se-r I found the other day. Anyway, this may be a dumb question but is it possible to throw a t28 or t25 into the ve's?
Also, maybe someone already have asked this question. But what would i need to have a complete VE swap?
Thanks for all the info.

Thanks again,

mike

Tom @ SR20development ran an amazing 13.50@100 recently at carlsbad raceway. this was with a POP charger and no exhaust.

with the right parts, 12s should be possible, granted it would take an amazing run, but nevertheless, possible.

i would not recommend turboing a VE motor.

What else was done to the car besides no exhaust? Was the car stripped in anyway (Spare, jack, passenger seats)? Also what was done to the engine? TIA

no interior door panels, rear seat, carpet. dash is still there (for now)

stock VE motor with stock DE (7500 rpm redline) computer and manual VVL control.

POP charger and no muffler, 2.25" crush bent piping.

thats all folks.

oh yeah, i think he was running 25 or 26" slicks, a little too large for this car.

this car would have been about 2-3 tenths faster if it had an 8000+ rpm redline (JWT can get the rev limit up to 81XX IIRC)

SR20loper

On the Manual VVL part did he just use a simple button like a on and off switch ? can we do that?

Rockwood

he used an rpm switch. it sees 4500 rpms and trips the solenoid.

SR20loper

So this guy was using a Stock ECU with some RPM tripper to set the VVL? what did he use do you know for sure? I'm intrested in the way he did it will save me alot of money

Rockwood

RPM switch from JCWhitney, $45 IIRC. dont know its exact name or anything, but you should be able to find it. don't know how he wired it, but it should be pretty easy.

92SE-R

Get a shift light. Instead of wiring the power to the shift light at a certain RPM, wire the power to the VVL solenoids.

How high could this engine be revved safely?

Rockwood

with a JWT ECU? 8000 is the highest a DE ECU can be safely programmed to.

with a stand alone, well, only one way to find out.....

CNibbana

There is already an MSD pil trigger kit that can trigger anything when your RPM hits the pil setting.

I'm thinking of using one of those.

What about NOS how much (safely) to shot? I know a guy from MN with a JDM sr20de shooting 100 shoot safely, doing 13's. Also (HotshtSR20) why not turbocharged any VE's or either ones.

Thanks,

mike

Rockwood

it is more work than it is worth, IMO.

too much overlap on the cams for boosted applications.

also the compression is too high for some real boost.

the cylinder head is pretty nice though, but you could always get a port job done on a DE for less money than buying a VE and droppping the compression, dicking with the cam timing to reduce overlap, etc...

NOS would be fine on the motor though. the CR may be too high for a 100 shot, but a 50 shot would kick a lot of ass with this motor. anyone know if the VE is more detonation resistant? does it have more quench area? guess the only way to figure out if the motor will take a 100 shot will be to plug it in and see how it goes, could get expensive though....

Lyn Labahn

High Compression works fine with nitrous.

Rockwood

yes it does, but higher compression means higher chance of detonation. Nitrous also increases chances of detonation. too much of either or both, and boom! thats why there aren't too many 11:1 100 shot SE-Rs. my friend tried it, and JWT had to fatten the mixture and take out too much timing as compared to a 9.5:1 motor to prevent it from blowing up (which it eventually did) and it ended up making less power.

Did it blow up despite what JWT did or was it from another reason?

Any ideas on what needs to be done to successfully run a 100 shot with 11:1 compression?

Would water injection work?
