Thomas.B Posted June 27, 2012 Share Posted June 27, 2012 Tried the search... Anyways, what is the max hp the standard engine (safely) can take? Remember reading somewhere in the 700 region? Thanks Quote Link to comment Share on other sites More sharing options...
Chris Bailey Posted June 27, 2012 Share Posted June 27, 2012 I think the stock block is good for about 600bhp. Someone will come along and tell you lol Quote Link to comment Share on other sites More sharing options...
listy Posted June 27, 2012 Share Posted June 27, 2012 iirc around the 700 mark (I *think*) then internal need to be played with Quote Link to comment Share on other sites More sharing options...
Dan_Turism0 Posted June 27, 2012 Share Posted June 27, 2012 tbh there's too many variables, hodge got 914bhp iirc on stock bottom end, but i suppose it depends on a few things health of engine/how hard it's driven to how long and max power it can take.

a98pmalcolm Posted June 28, 2012 Share Posted June 28, 2012 700 is the correct figure.. Thats why when I go single im staying 50 below Quote Link to comment Share on other sites More sharing options...
Mario Posted June 28, 2012 Share Posted June 28, 2012 There has been a topic about just that not too long ago, http://www.mkivsupra.net/vbb/showthread.php?270867-Are-you-in-the-700bhp-club Quote Link to comment Share on other sites More sharing options...
mark newman Posted June 28, 2012 Share Posted June 28, 2012 around 850bhp just change the cams, Quote Link to comment Share on other sites More sharing options...
mellonman Posted June 28, 2012 Share Posted June 28, 2012 its a weigh of the more power you put in the less reliable it will be Mr T thought this weigh off was at 320bhp for a good car smooth 0-60 and 100% reliable so my fag packet maths would put it at if you doubled the power you half the reliablity so 640bhp will make you engine 50% less reliable, so if you are putting that full 640bhp through the car for a long time expect it to brake, aditional coolers are needed to bump that reliablity up Quote Link to comment Share on other sites More sharing options...
Boge Posted June 28, 2012 Share Posted June 28, 2012 They built the engine for about 600bhp but had to limit this due to emissions standards therefore I'd guess around 600 Quote Link to comment Share on other sites More sharing options...

listy Posted June 28, 2012 Share Posted June 28, 2012 I read this somewhere a while ago too. Can't remember where though. Except I read the reason for less power than what it was capable of was due to the lack of market for a high powered car at the time Quote Link to comment Share on other sites More sharing options...
Matt H Posted June 28, 2012 Share Posted June 28, 2012 They also had an agreement at the time that they wouldn't make over 300bhp cars in Japan (or something like that) Quote Link to comment Share on other sites More sharing options...
Kaan W Posted June 28, 2012 Share Posted June 28, 2012 Theres alot of answers here but he never mentioned what engine? But assuming he means a 2JZGTE could be anything. Could be 400hp if it revs to 15000rpm. Stay below 700hp and 7500rpm and you should be ok.. Quote Link to comment Share on other sites More sharing options...
Thorin Posted June 28, 2012 Share Posted June 28, 2012 1 million HP. Quote Link to comment Share on other sites More sharing options...
Abz Posted June 28, 2012 Share Posted June 28, 2012 Too many factors to determine an actual number, the round safe figure does seem to be 600bhp though people have ran more than this. Quote Link to comment Share on other sites More sharing options...
Ian C Posted June 28, 2012 Share Posted June 28, 2012 The VVTi engine had a 7200rpm rev limit, and exactly the same internals, so I'd say that's a nice same rev limit for reliability. As for power, well, they seem to run 500 to 600bhp happily for years, there are a lot of examples of well-maintained and tuned stock motors doing that. Beyond that you get a smaller sample set, shorter time, and more unknowns. Quote Link to comment Share on other sites More sharing options...
David P Posted June 28, 2012 Share Posted June 28, 2012 I thought the con-rods were lighter and weaker in the VVTI? Quote Link to comment Share on other sites More sharing options...
Noz Posted June 28, 2012 Share Posted June 28, 2012 Chris Wilson would know about the rods. They are same NA and TT not sure about VVTi, even have the same part number apparently. Quote Link to comment Share on other sites More sharing options...

Beyond that you get a smaller sample set, shorter time, and more unknowns. It's all in the setup and mapping, some 800hp stock motors will be more reliable than 500hp ones due to being setup correctly. From what I've read on the net, engine building often causes as many issues as it solves. Quote Link to comment Share on other sites More sharing options...

Luxluc Posted June 28, 2012 Share Posted June 28, 2012 There are a lot of high power Supras with stock engine. High rev will kill an engine faster than hp. We have 2 single Supras over here (in Luxembourg) ... and the other guy has set the rev limit to 7750 on a complete stock block with a GT42 turbo .. running 2 bar of boost on E85. However, for those who want reliability : keep you Supra stock, and it will last very long. Quote Link to comment Share on other sites More sharing options...
Kirk Posted June 28, 2012 Share Posted June 28, 2012 I thought the con-rods were lighter and weaker in the VVTI? That's only on the later GE engine. Gold rod GTE VVt-i, Silver GE VVt-i. Quote Link to comment Share on other sites More sharing options...
