What material pieces put? how much power support?

1º I have been told that these are approximately the first changes I should do ... so I would like to know if this is true and what brands to put each case

+ 1 bar turbo
+ down pipe and exaust
+ improve admission
+ isolate collectors
+ Wastegate yes or no? I do not know if it is necessary or the exact function when changing
+ bov and wastegate?
+ I have been told that the ST205 camshafts are good, worth this change? the car works correctly without changing the ECU?

Why buy EBC
What downpipe and exhaust buy. 2.5 2.7 or 3


2º how much power the original mechanical supports reliably. the car has 220.000km, did not convert to miles

There is some information in the forum, but as time passes data are changing ...


3º regardless, forged pistons and connecting rods what would you recommend me ride? I do not mind spending on the car, but if they are even better quality and economical.

and head gasket?

Ebay.es a seller or shipments to Spain

thank you very much

The factory fuel cut is at 1 bar, so I'd stay a bit below that. Downpipe and exhaust will increase the boost level, so do that being doing anything else (EBC, MBC) to increase it. Leave the stock wastegate, and don't bother with a BOV (no benefit on these engines). 205 or 204 cams are an upgrade but only worth doing if you already have the engine apart. There is a thread on here comparing the specs of all the cams.

The MR2 Power Primer is still pretty relevant, but with 220k I'd be careful about trying to increase the power too much.

Rods and pistons depend on your power goals, the stock rods are good for quite a bit of power so you can probably stick with those if they're in good shape. Head gasket I'd suggest the OEM ST205 one, but it depends how much material is removed from the block and head during machining.

So if to increase the pressure above 1 bar should put another bomb?
Injectors also would have to mount or only pump enough?
What bomb recommend me? You would have to put a pressure controller to limit it?

How reliable can have the turbo above 1 bar? km or miles approximate being a new turbo

Have the engine apart? I do not understand, refers if I have the valve cover off the engine or engine removed?

To mount camshafts 264 and / or 272 ecu need?

There are other better and compatible cams in between the original and HKS 264 cams?

But about how much power is capable of supporting a standard engine 3sgte stock. Generally, even think that is an engine with 0KM

Cuánta potencia aguantan las rods originales?

No es indiferente la marca y potencia en material forjado? éste no aguanta más o menos la misma potencia sea wossner o wiseco por ejemplo?

Pistones para 250-300cv? para 300-350 cv y para 350-400cv?
Mi meta aproximada 240-270cv

head gasket oem St 205 es mejor que cometic?

Qué compresión me aconsejais dejar? la original o una menor para aumentar el boost?

----------------------------------------

What material advise me for named parts?

Down pipe and exaust
Down pipe and exaust what diameter?
Electronic boost controler
Air filter or/and box air filter

thank you very much. Really
