xsspeed Posted November 15, 2009 Share Posted November 15, 2009 So I am getting nasty thoughts about this 'trd spec' 2e motor. It has a manifold for carbs that I assume to be for side draughts, though will need to confirm this. Given the motor is a 1300, what sort of size should I be looking at for the carbs? According to the reliable trademe twin 35's seem to be fine for anything from 1000cc to 2500cc. However I can't grasp that unless there is consideable choking involved. So far looking at both dellorto and weber, have heard of tuneability issues with weber, though this may be for twin sidedraughts in general? Any other brands I should look at? Also had the thought about bike carbs, but I know even less about these than I do about normal carbs. I understand one of the issues with bike carbs is getting a vacuum for the brake booster? If anyone has ideas/point me in the direction of a good website or book, that'd be ace. Cheers Stevo Quote Link to comment Share on other sites More sharing options...
shizzl Posted November 15, 2009 Share Posted November 15, 2009 id thought twin 40s, as theyr really common.. if you find it hard getting vacuum for the booster then you could always run a diesel alt, they have the vac pump system in them...... well i think they do anyway Quote Link to comment Share on other sites More sharing options...
Unclejake Posted November 16, 2009 Share Posted November 16, 2009 Dellorto make a 36mm carb but are harder to find bits for than a Weber. You want the smallest carbs you can find for a small motor on the street. A single 40mm would be pretty choice Quote Link to comment Share on other sites More sharing options...
mikuni Posted November 16, 2009 Share Posted November 16, 2009 You want the smallest carbs you can find for a small motor on the street. A single 40mm would be pretty choice Motor in question is this http://www.trademe.co.nz/Browse/SearchR ... ype=Search Apparently making 160hp in its "hay day", so would likely be able to support twin 40's without too much trouble.

xsspeed Posted November 16, 2009 Author Share Posted November 16, 2009 yeah thats the one I'm a bit sceptical of the 160hp but the seller has said that that was balls to wall on the edge (timing at 38deg btdc + adj cam gear at full) and would suit daily application at 120-130hp (detune by retard timing etc) It would be nice to have and different but like you said mikuni reliability is a factor, plus in my mind spares and availability is another (not many spares kicking around for these) Quote Link to comment Share on other sites More sharing options...
shizzl Posted November 16, 2009 Share Posted November 16, 2009 holy shitzen burger....40s would suit it nicely IMHO Quote Link to comment Share on other sites More sharing options...
Spencer Posted November 16, 2009 Share Posted November 16, 2009 You should seriously think about individual thottles and injection, it will be allot better to drive with those cams injected. I would steer clear dude changing a mount and wiring injection is no biggie compared to the issues you could have with that. Sounds like the blocks stuffed so you need a bore and OS pistons, or a new block. Can you get rings for those pistons? what condition is the crank and head in? etc etc. Plus the ports and combustion chamber are pretty shit looking (from those photos anyway) Quote Link to comment Share on other sites More sharing options...
xsspeed Posted November 16, 2009 Author Share Posted November 16, 2009 Yeah, all point you have raised I have been chatting to the guy about (except ports). As for rings he was gunna check if std toyota ones fit. Would have to get a new block, but thats easy. Marku (the GC) was gunna have a look at it when he has time so will wait for a condition report from him. The more I think about it now the more its seems like me having pipe dreams, and I should just stick to what I was planning with the 4age, especially seeing besides the mount and getting it wired, everything I need I already have.

Truenotch Posted November 16, 2009 Share Posted November 16, 2009 I caught up with him in the weekend and am planning to go have a look for you soon. I reckon 35mm DHLB's would suit depending on the spacing on that manifold. Quote Link to comment Share on other sites More sharing options...
xsspeed Posted November 16, 2009 Author Share Posted November 16, 2009 thanks mate, will be interested to hear your thoughts edit: also it was the dellorto weber dhlb's on TM that I was looking at, just don't know if the info is correct. auction here: http://www.trademe.co.nz/Browse/Listing.aspx?id=253702877 Quote Link to comment Share on other sites More sharing options...
Spencer Posted November 16, 2009 Share Posted November 16, 2009 Just had another look at the trademe add, those are factory rods aye? and that flywheel looks pretty shit for an engine thats 'TRD spec'. It looks very questionable to me, I'd love to see more pics of ports, top of the pistons etc Quote Link to comment Share on other sites More sharing options...
xsspeed Posted November 16, 2009 Author Share Posted November 16, 2009 Yeah std rods, and crank is from a 2e-t. I can post more pics, top of pistons are quite black, not sure on surface condition though. Was wanting to see what marku thought in person. perhaps i should change title of this thread. I chatted to a guy on toyspeed who used to race or crew for the ep71's back in the day, he seemed to think it was all above board. Quote Link to comment Share on other sites More sharing options...
