It bolted right up without any modifications. I was very pleased ;-) The car feels great except for some low to mid throttle surging. I ruled out a/f problems so it must have something to do with timing or perhaps a faulty coil or something. I really got on it for the first time yesterday and it's by far much faster than my full bolt on DE motor. Cruising up hills on the expressway in 5th gear and the thing pulls hard. I'm having it dyno tuned in Toronto in a few weeks and hopefully we can determine what's causing the surging problem. I'll post results later.

I'm using the JWT unit with the VE MAF but I think I'm going to start working with this guy in Toronto instead of JWT. He has the knowledge to manipulate Nissan ECU's and is only 3 hours away so I can drive the car there to have it dyno tuned as part of the package.
What excites me about this is the fact that he'll tune the car on the dyno for maximum performance after making the necessary adjustments to the ECU. No more guess work.
He's a genius. I saw him at the dyno last summer, and he got *major* power out of the race car NX2000 that dgerryts works on. I'm sure he'll get everything running great.

I can't believe what I am hearing. This is amazing. Keep us informed.

You guys are not helping at all save me some money! Do you know that this kind of information is VERY DEADLY and can empty out my bank! Oh my gosh that is just some good information and making me just want to buy that VE as we speak.

Let's not start the celebration just yet. Proof is in the numbers and driveability after the tuning has been done. It is a step in the right direction though. Having an expert tuner on this side of the country is huge. Having the Canadian exchange rate is icing on the cake if this guy can post positive results. I'll provide all the details once I have him dyno tune the car.

Yes, But I have a computer over at JWT that I would prefer to have done on the dyno with him. IF he can tune a 95 ECU I don't see how his dyno tuned program could be worse then the JWT program. I know we wont know until we see the proof but I don't want to pay for the JWT program and then need this guy to fix it. I don't know what to do????? ARGHHHHH.

Not only that but aren't you installing an SR16VE stroked to 2.0 liters? With the different cams I'm not sure you can rely on a program developed for the regular SR20VE.
How much do you owe JWT? If it is just the regular $100 ECU upgrade then just get it done and if the guy in Toronto proves himself then you can just drive up there whenever you're ready. If on the otherhand this is your first JWT ECU then I'd be inclined to tell them to hold off until Shuey gets his tuned and can provide you feedback.

I don't know if anyone else really cares but here we go. I wanted the sr16ve built into a sr20ve to get the better cams. This is proving to be harder then it seems. Andreas is needing to get custom pistons made or use the de pistons which will result in a slighlty lower compression then 11:1 (this is what he told me). I don't really want to spend the money on custom forged pistons (starting to feel the pain of money leaving my pocket very quickly). So I don't know what engine I will get. The sr20ve is in impound right now and may be commited to someone else.
JWT is another story. They seem to not have a program that works on the East coast. All the CA cars seem fine. They also tell me the stock program will work fine with the sr16 cams. I am a little skeptical at this point. Does anyone have a JWT ecu on a VE that runs right. Big Tom?? Anyone??

I'm pretty sure that you can get an 86mm Nissan 10.5:1 piston that will work (I'll try to dig up a part number). What about going with a 1mm over bore and using an 87mm piston from one of the 300Z engines? This was a common build up on the "Kojima" 11:1 engine. Might require that Andreas have a torque plate, though.
I keep seeing B18 vtec motors running 12.5 CR on pump gas. I reason this is possible b/c the motor is very resistant against detenation. But can someone fill me in on the details. And can the same be said about the SR20VE?
Originally posted by 98sr20de There are valve reliefs cut into the top of the VE pistons that probably would need to be present on any 11:1 engine with the sr16ve cams.
Yuk! Is there a reason you couldn't use the SR20VE pistons or are they just hard to come by?

Good to hear. I've received a few private emails from guys who either know him or have heard of him and they all say the same thing.
