[Mk2] [Turbo] rev 3 turbo 300bhp wanted

[mr2targa]

i have a rev 3 turbo with the following mods and am looking for 300 hp
need to know what may be required
currently have a hks intake, mongoose system and a gredy intercooler and hard pipes on order?
looking for some pointers

[dbiagioni]

Depends how well the car is running and how well it has been maintained. If its a healthy one those mods with an ebc or mbc set @ 1.2 bar + decat should do it fwhp.

[mr2targa]

well only got 68,000 mile on the clock maintained regardless of cost ex imoc car all sound and running well.
looking for 300hp and reliable?

[djpkins]

power fc mapped by somebody sensible mate...and as said, you could achieve that with a hike in boost...if you want a reliable and safe car that you can run everyday without worries, I would personally stay around 280bhp with what you have or get a mappable ecu and get it mapped to your car, I have seen people selling Power FC's with "300bhp ready to go...plug and play..." not the case, it needs to be tuned to your car.

[bobhatton]

You can get 300hp with the mods you have, just turn the boost up and retard the timing to 8 deg btdc

[swaggansway]

bob, how does retarding timing increase bhp? what are the sideaffects of doing this?

[bobhatton]

It does not give more power, it helps to stop blowing the engine up

[swaggansway]

u mean like mine just did lol. i will look into why and how

[bobhatton]

I know why and how.

Just tell me what you want from the engine and I can tell you what you need when you rebuild it

[swaggansway]

eventualy 500 bhp, i am starting build tomorow my forgies and acls are taking so long to get here! guessing i need a better turbo than my ct20b, charge cooler, rev3 convertion , 3" exhsust straight through, better ecu and many more parts

hoping standard con rods and crank are good for this?

[Marf]

You said 400 in the other thread!

[bobhatton]

I can tell you now the pistons will be wrong, you cannot just get off the shelve pistons, they have to be designed for the engine and are one of the last things that will be sized after the full engine design has been completed.

this summer but potentualy i wood like 500 max

[swaggansway]

bob, so what is the max i can ask from my wosner pistons safley? wosner did say if i design pistons they would make them for me but i think that is way off yet

OK, so you should have said that from the start then, you need to spec your engine for your final power goal, not yuor interim goals. That is unless you have some kind of fetish where you get off on rebuilding engines

[swaggansway]

funny u should say that i love stripping engins lol

but yes i realy should make this the the last time as it has kicked a massive hole in my bank account

[swaggansway]

I have changed my mind op. DON'T TURN YOUR BOOST UP. take your car to a pro and get them to do it. you don't know how much has been taken of head or face in past therefore your compression could be, well anything!!! I just don't want you having a accident like me! there are so many factors and such that need to be taken into consideration and every engine is different.

Bob - surely increasing the boost 'slightly' but advancing the ignition slightly would be better than increasing the boost 'more' and retarding the ignition? It might produce less torque this way but the gains would be more wide spread over the rev range?
