I duno about other r34's but mine is very smooth to drive around town, and if you want to hoon around like every other retard it does 0-40 in 1st gear pretty fast with great response.

Custom stainless steel intake with pod and 2 1/4 inch exhaust with wide rear tires = pretty good power in low - mid range

Pick the cr you like the best...not like you drive it everywhere at WOT and 7k rpm.....for street duties the Supra gets my vote simple because of the bigger motor, same brakes as the turbo model etc...so later, just throw a GT42 at it and run 9's

Only the SZ-R (which is substantially more expensive) and some SZs with the big brake option have the same brakes as the turbo models. Mine are piddly little 2/1 pot. Word of warning, IF you do decide to go the Supra route with the intention of turbo charging it later, buy the SZ-R, not just because of the improved brakes, diff, etc, but most importantly because it has the Getrag 6spd. The 5spd will bust at around 250rwkw which isn't much in the 2J world.

You would be better off looking at the overalls of a car...SSS pulsars are by far the fastest affordable P plater car going around because we know a lotus or somehing is just a joke :)

With my GTS-4 its was pretty slow so i rebored and honed it out too a 2.7L ( + compleate engine rebuild) and a exedy heavy duty clutch (thats all it needed) and it was already faster than a NA supra by far and lots of other cars but thats only speed. The supra's brakes out do NA skyline brakes two times over so if you come through corners the supra was always entering faster. But then again once im off my P's a rb26 just drops right into the car with the added adition of wiring looms and a ecu so its just what suits me not whats best on papper.

Just giving examples, you should buy what best suits you, not what is the best on papper.

How much power did you get from the rebore + hone??

80thou over will put you in the water jacket...would redefine "floating" wrist pins lol.

A simple overbore wont net you anymore than a couple of horsepower, so unless you did a heap of headwork/cams/ecu/compression etc.

So my guess is the motor was Fubar so it felt quicker when it was running properly.

As for the supra brakes, only the 1996-> got the big 4 pots, the early ones has the same brakes as my soarer/non-turbo supras.

Well 40thou is the norm, I personally know people who have gone custom 60thou, and I have seen 80thou RB26 pistons for sale before (which you would need for RB26 crank) but have no experience with them of course.

Thin cyl walls are never a good idea for high power FI, but I doubt it would be an issue for a well made N/A. Problem with this is you would need custom pistons (probably RB25DE dome with RB26 pin height) or you would lose any capacity benefit due to compression loss.

Anyway, off topic.

The problem going with 88mm slugs is the bore degradation after nearly 20 years of use, if you pop the welch plugs out you will see how badly the outside of he bores are rusted.

So If I were to go 80thou over (88mm) I would x-ray the shit outta the block so see how much meat there is, some blocks wont even take 60thou due to core shift when being cast, Or I would sleeve the block.

E.g 10-15 years ago you could take a small block ford (windsor or cleveland) out 60thou, these days no-one goes past 40 because a fair bit of the bores have rusted away and you will more than likely hole the bores, generally towards the bottom of the liner as they are thinner than up the top.

Yeah I know what you mean, I replaced the head on a mates RB25DET because it blew the gasket (well so I thought), but in actual fact the coolant channel had corroded into the combustion chamber couple cylinders (just on the edge of the gasket)...

The older crowd that push the old 8's to the limits are the most known with these issues, just keep going through blocks until one sticks.

But yeah, as long as you have a good block to start with it wont be an issue - while x raying is the safest option, you should be able to tell the condition of the block just by looking at the visible parts, if there is obvious signs or corrosion, then give that extra 60cc a miss...

      Boost level and torque curve

      By Lithium · Posted

      There is a LOT of stuff that can be done, it all depends on how much time and money you want to spend on doing in.  Not all ECUs will be able to do it, and the more control you need the more time and knowledge needs to be put into making it work.  If you're willing to spend the time and money and have the right hardware and skills involved there's a lot that can be done.

      I am impressed with all this level of adjustment. I didn't expect all this possibility

      Boost level and torque curve

      By Lithium · Posted

      Correct.  In the case of the 500kw dyno plot I showed you the car actually runs two boost control solenoids for boost control and a 5psi wastegate spring.  It allows me to control how much boost pressure is applied to both sides of the wastegate valve at any point and fairly accurately control boost target as a result. I've tuned it so that it's able to target anywhere from 5psi to 25psi depending on what's needed.  The target tables I've set up in that car are Gear vs RPM, so every gear has potential for a different boost (and torque) curve.   First and second gear have quite low boost targets, third gear actually has different target boost all the way through the rpm range as it's a stock RB25 gearbox - the boost targets have been chosen to maintain a peak of 600nm (what the owner has set as the maximum torque he's happy with putting through the stock 3rd gear) but it carries that to the rev limiter.   The boost curve to achieve that is something of a ramp up, then hold, then ramp up again and the power curve looks more like a flat line haha.

      so you can decrease or increase the boost depending on the diet as you wish?     by acting on the wastegate?

      That's torque and power, it's all from a single run.  The boost curve is "held back" from it's peak target in the 3500rpm to 5000rpm range from memory, so it ramps hard to something like 18psi then climbs more progressively to 23psi nearer 5000rpm.   It makes the torque (and power) ramp more "natural" and less hard on parts and traction, it doesn't feel artificially held back.
