first mods to do?
Guys, please help me! I'm getting an evo V real soon but I live in the US. I already have an intake, exhaust, and boost controller. I heard to be safe, I shouldn't go higher than 1.2 bars. I was wondering what would be the first mods to do to my evo. I heard that I really want performance, I need a remapped ecu and fuel stuff. I was wondering what one would suggest for the first couple of mods for my evo. I live in the states too. thanks!

I've heard a nie way to get more performance not to mention a longer engine life is replacing the engine internals.
I'm not massively informative on the engine aspects, so somebody tell me if I'm an idiot er not.

you need to see if your exhaust is complete, for example turbo elbow,downpipe, decat pie, mid section and rear muffler like the hks extension kit and hyper muffler, and if the air filter is an induction kit as hks rs kit or blitz.
After that, you can fit a new ecu. The ralliart sports ecu works well but it's made to be used with good fuel, around 98ron and with free flow exhaust and filter. It's a good deal if you can get it at the japanese price, at around 1000$. If it cost more than that you can buy better stuff like gems in uk, or go for another ecu like mine's or blitz.
These kind of setup will allow you to run 1.4bars without fuel cut and giving the right fuel.

You can run up to 1.5 bars mid range no pbs, but may get fuel cut depending on the ECU you have. There is something in the FAQ about this. You may run 1.2 bars approx with the OEM ECU.
Monitor the air fuel mixture with a wideband lamda when setting this up not to go over 12.5 - 13.

japspec4g63, look into getting an Apexi Power FC with controller. It's very easy to tune, but is a full ECU replacement so you can enter the maps for timing, fuel, boost, etc. I know someone who is extremely reliable and should be able to get you a unit. My guess is that price would be around $1300 or so. Here's his website:

Another place that may be able to get them is rx7-store.net:

Internals
I recommend replacing the ARP bolts first to ensure that the conrod doesn't separarte from its big end cap as you search for increased RPM and boost. You can then increase boost to around 1.3 bar before strengthened conrods are needed. With this done put a freer flowing exhaust and induction system in place and use a reprogrammed ECU to handle the increased airflow and fueling - Stage 1 (300+BHP).
A strengthened crank, thrust bearing, forged pistons and conrods will permit you to run the engine harder still. However, you'll not see the full benefits without further developing the exhaust, induction, fuel delivery and ECU. Extra BHP can be achieved by gas-flowing the head, and polishing the ports, induction manifold and exhaust manifold. Larger injectors and higher capacity fuel pump are required for higher states of tune. Also check you're running the correct density spark plugs. BR7 is fine for normal states of tune but faster running requires BR8 or BR9 for high states of tune.
Fully bored out to a combined capacity of 2.3L, equipped with a bigger turbo, a competition manifold, a Group A steel crank, forged pistons and conrods, full anti-lag system, bigger fuel pump and injectors, Motec or Gems tuned ECU, competition exhaust and other mods, 500+bhp and 460+lbft is possible. Not for the shopping though.
Summary:
1. ARP bolts.
2. Exhaust, Induction & ECU (upto 1.3bar - brakes? AP 6pot 332mm?).
3. Strengthened crank, thrust bearings, forged pistons and conrods, uprated dump-valve, uprated standard clutch or single plate cerametallic paddle clutch, and EvoVI intercooler, or other + freer flowing boost pipe (upto 1.4bar).
4. Boost and fuel controllers - e.g. Apexi AVC-R and Super AFC - multi-plate clutch, and modified inlet & exhaust cams (upto 1.6 bar).
5. Consult a specialist if you require any further mods (you nutter ).

no, I didn't buy it in VA. I was trying to sell my evo IV conversion, I think that's what you're thinking of. anyways, someone was selling it as a track car and I got lucky! thanks for all your help guys! how much hp are stock internals capable of handling safely? thanks!

Ths pistons on 5s are different than 6s so I don't know if they can take as much boost as a 6. A 6 can live with 1.6 bar, some say you need to replace the conrod bolts, some say you don't. Either way, have never heard of a bigend failure on a 6, so that kinda favours the last group. Don't go buying a cerametallic clutch though, unless you go for silly HP, otherwise an AP organic clutch will take up to 400bhp.

JUN have a US branch, the search found the website below but it wouldn't load for me. Maybe you'll have better luck being in the US.

I love this forum. thanks guys, you guys are very helpful. I'm still a newbie to real evos, even though I've been following them since 98. let's talk about price. how much would a set of ARP bolts cost? what would you do with a $2000 budget? and how much hp gain could I get with this? same question for a $3000 budget. and same for a $4000. I was just wondering what you guys would do on these budgets and how much gains you would get. thanks! (don't include labor prices)

Jaffa,
how can you say that the big end bolts need to be done for ANY boost going above standard. There are many 1.5 bar Lancers out there that have no problems whatsoever. Or do you have an example of an Evo on which the big-end bolts failed (running less than 1.6)? I would be very interested to hear about that.
And how exactly are you looking to extract 350 bhp at 1.3 bar, assuming that you're using tha standard turbo?? 330 is realistic but 350... would love to see that.
