Ok, here's the deal...I'm looking to build a 1.6td with around 130hp. I've read numerous posts which lead me to believe this is possible. I have all the basics down, giles pump, arp studs, etc. Can anyone tell me where I can expect peak torque to be. I'm putting this engine in a Toyota truck and I'm ready to order gears and tires. Does anyone have a dyno graph of a similar engine that they can post? I know that you guys can't tell me exact numbers as each engine build is different (pump timing, fuel curve, etc.) I just need to know an estimate. A popular setup is 4.88 gears and 32" tires. This combination puts engine rpm at 2800 @ 65mph/5th gear. Would this be low? high? Thoughts? Thanks.
If you do nothing but the Giles pump you could see up to 50% over stock HP with the 1.6 and the T-3 or KKK24. Stock HP #s were around 78 so add about 39 to it....carry the one...scratch head...add ... should be about 117. Giles says up to 50% on some engines so say u only get 110 out of the pump. Intercool it and add more fuel and boost you should be able to achieve the 130 mark. Some have had better luck with VNT or Big Ball bearing turbos, but I don't have any experience there.120ish was my goal, but I just figured I would build the best engine I could at a cheap price. I had the head ported, block cleaned up and new pistons, metal HG, ARP studs, Giles pump, and hopefully a clutch that will handle it. I was hoping for 120HP or better, just so I could keep up with moms TDI. After reading and doing a little more I think I will be able to achieve my goal. Search on build threads. Saurkrat, 53 willys, smoking eddy, and many more I can't remember all have much to learn from if you haven't seen their threads already. Also FAQ has Make your 1.6 a faster car that is helpful.
if you are using a toyota trans/tc, there is no way in hell you are gonna turn 2800 at 65mph. i have 4.10s and 35's and i turn almost 3000 rpms at 65mph. 4.88 gears are WAY WAY lower, almost a full turn of the engine to make the tires turn the same. i also have a R150 trans. it has a higher 5th gear than your 4cyl trans. i would see how it works with the 4.10s first. its going to have more power and WAY more torque than a stock 22r could dream of having. a lighter engine with more power? why do you need to gear it? gearing something is just a stupid way of making it go better with no power.

I'm also going intercooled (plus a full set of gauges) to keep the tops of the pistons solid, as opposed to semi-liquid. Thanks for the list of user names, that should narrow the search function. One question comes up; it seems to me that doubling the output of these engines would tax the stock turbo. I understand that at some point, its going to run out of breath. I checked garrett's web site and it looks like they make a turbo for everything. Do they make one that's an upgrade for the factory unit? That is, do they make a turbo thats better suited to operate on these diesels running the amount of fuel/boost that the above mentioned engine would? I don't know how to read turbo maps so I'd be guessing at best (I know, no guessing allowed so I'll leave it up to the experts). As far as mounting options, I have access to a machine shop with enough tools to make just about anything. A nice stainless adapter wouldn't be too much of a hassle.

So, 4.10 gears on 35" tires puts your engine rpm around 2150 @ 65mph. Either something is slipping or your tach is off.Another thought...You are running tires that are 25% bigger than the factory tire. If you didn't re-gear the speedo, you're traveling 25% faster than your speedo says. That being said, when your speedo reads 65mph, you are traveling 81mph. With the above mentioned tire/gear combination your tach would read somewhere around 2680rpm.
like i said tho, try your engine with the gears you got. it will go better than a factory 22r/re.
