Kent Phil Posted November 5, 2003 Share Posted November 5, 2003 Y'all, Is there a general consensus of option about this yet? I've got the option of a facelift non-VVTI TT and was jsut wondering what y'all thought of the two engines. Hope this don't start a war, as at my usual home this kinda question cuses Flame Wars! Thanks, Phil. Quote Link to comment Share on other sites More sharing options...
Steve W2 Posted November 5, 2003 Share Posted November 5, 2003 Hello and welcome. I think the general consensus is that the VVTI have a few more ponies and a little more torque but are more difficult to mod as they are more clever than the non VVTI versions. Personally I would think either are a good choice if you haven't got big power mods planned. Quote Link to comment Share on other sites More sharing options...
Kent Phil Posted November 5, 2003 Author Share Posted November 5, 2003 Well, I was hoping to be Mr Stock, but the general opinion is that I won't be able to resist !!! Phil. Quote Link to comment Share on other sites More sharing options...
eyefi Posted November 5, 2003 Share Posted November 5, 2003 the vvti's r more expensive and awkward to mod. ive never seen one go single turbo. aftermarket cams r hard to find for em Quote Link to comment Share on other sites More sharing options...
Guest Terry S Posted November 5, 2003 Share Posted November 5, 2003 I have been looking into the logistics of modding VVTi cars as more come into the country. Basically the main restriction is the MAF sensor. If you only ever wanted 500 bhp this shouldn't be an issue. Cams are a PITA but the stock ones are pretty good. Rob Oldham's VVTI car pulls like a train. Quote Link to comment Share on other sites More sharing options...
trooper Posted November 5, 2003 Share Posted November 5, 2003 The VVTi is rated at 280PS same as the non-VVTi This is what Toyota say, I've never seen any independant measurements. The torque should be 338lb.ft compared to 318lb.ft Applies for Jap cars only. Quote Link to comment Share on other sites More sharing options...
Guest Terry S Posted November 5, 2003 Share Posted November 5, 2003 VVTi's make more power & torque. It's not a massive diiference, but it's there. Quote Link to comment Share on other sites More sharing options...
Guest Terry S Posted November 5, 2003 Share Posted November 5, 2003 BTW aren't you amazed just how many Jap cars make exactly 280 bhp? Quote Link to comment Share on other sites More sharing options...

trooper Posted November 5, 2003 Share Posted November 5, 2003 280PS (276BHP) is the maximum power output agreed between the Jap manufactures and the powers that be. As the rest of the world is so so power crazy right now with 400BHP to 550BHP the norm, I think that agreement will be disolved. Here's hoping!

Go way.... and there was me thinking they all produced exactly the same power levels. Quote Link to comment Share on other sites More sharing options...

trooper Posted November 5, 2003 Share Posted November 5, 2003 It's cool I walked into that one. It would be interesting to have readouts for all the different cars to see how close all the manufactures were. I see models from 2.0 to 4.3 all with 280PS, it seems likely that some aren't telling the whole truth. Quote Link to comment Share on other sites More sharing options...
Guest Terry S Posted November 5, 2003 Share Posted November 5, 2003 Nick Sorry:p Trooper, the info is out there. The stock JDM & UK cars make 320 ish. Newer Evo's well over 300. They all lie. The VVTi seem to make about 20 bhp more from a few sheets I have seen. Quote Link to comment Share on other sites More sharing options...

I've always planned on getting a VVTI in 2034 when I've finally paid the loan off on my current one Is that HKS Valcon system any good?

Nick Posted November 5, 2003 Share Posted November 5, 2003 I've had my VVT-i TT for 3 years now and with a full decat it's great to drive, definitely more responsive than a normal TT. Tuning's a bit of a grey area once you start talking about changing the turbos, I don't know anyone running a heavily modded VVT-i. I've spoken to ChrisW about fitting larger twins/single properly setup on a MOTEC and this is still something I'm considering. I'm also in Kent so if you want a demo PM me and we're meet up. If after a spin in my car you think you'd want more power wise then maybe the non VVT-i would be for you. It would be easier and cheaper to mod, but not necessarily better....

I've always planned on getting a VVTI in 2034 when I've finally paid the loan off on my current one Is that HKS Valcon system any good? I * think* it may be the GReddy e-manage system, asthis lets you convert to a MAP sensor pretty easily. I am still trying to find out if it fits the VVTi as they don't list it......however they do list a 2jz-gte VVTi for a lexus:conf: I am pretty sure they will be the same but can't get a definitive answer. TBH I haven't looked at the HKS Valcon. Have you got any links? Quote Link to comment Share on other sites More sharing options...
Nic Posted November 6, 2003 Share Posted November 6, 2003 I have a e-manage fitted to my car (non- VVTI) it was fitted by the main Greddy agent here in HK, next time I'm there I'll ask them if they can be fitted to a VVTI. Quote Link to comment Share on other sites More sharing options...
Guest Terry S Posted November 6, 2003 Share Posted November 6, 2003 Thanks Nic, would be much appreciated. Quote Link to comment Share on other sites More sharing options...
Adam W Posted November 6, 2003 Share Posted November 6, 2003 I've done a lot of research on the E-manage and it appears to me that you have to use the MAP sensor alonside the original airflow meter, ie you can't ditch your MAF with it. Be interesting to hear what Nics bods say though. Quote Link to comment Share on other sites More sharing options...
Guest Terry S Posted November 6, 2003 Share Posted November 6, 2003 Yes Adam, but I think you can use the MAP sensor to enable you to run bigger injectors. The only other thing may be the dual MAF trimmed with an SAFC of similar. Quote Link to comment Share on other sites More sharing options...
Thorin Posted November 6, 2003 Share Posted November 6, 2003 Originally posted by Terry S TBH I haven't looked at the HKS Valcon. Have you got any links? No I've tried looking into them but there's bugger all information about it out there in the interweb. I do know that TDi have fitted at least a couple of them to VVTI supe's. Shame Nathan doesn't post any more. Quote Link to comment Share on other sites More sharing options...
trooper Posted November 7, 2003 Share Posted November 7, 2003 I presume that's a typ error, otherwise that's the mother of all loans... 2034! So the word on the street is that my VVTi makes 340BHP? It's quick but not 340BHP quick. Maybe mine's not working as it should. I'll have to get it measured. It feels like 280 under my foot.

Standard J-Spec's have been dyno'd at over 300bhp. The 280 limit is not strictly kept to Quote Link to comment Share on other sites More sharing options...
Nic Posted November 7, 2003 Share Posted November 7, 2003 Terry, I spoke to the owner of the Greddy dealer tonight and he said that the e-manage can be fitted to the VVTi Supra and that the e-manage can be set up to work with the MAF sensor. He told me they had already fitted them to a couple of cars here. cheers Quote Link to comment Share on other sites More sharing options...
