My car has been running in the high 200's for 3 years, now it's about 300 bhp (getting it RR'd on sat) and I dont plan on taking it any further than that.

It's unmapped running GT28R. I usually drive off boost, and rarely explore the top end of the rev gauge. 5000 miles a year, 91,000 on the clock.

If it goes pop I cant afford a rebuild, but it's perfect at the moment.

How long do you think it's likely to last?

Do you think this kind of power will kill it over time?

one you get all your mods I would recommend getting it mapped. be worth it IMO!

A while. They normally go pop when they've been driven fairly hard and on boost ALOT.

Got all my mods already, everything is fitted and working... no more Civic Type R's blasting past me on narrow country lanes!

Even if it runs perfect on the RR with no trace of det, and perfect fuelling at 1.3 bar, would mapping still make it safer or more efficient? That £500 would be very happily spent on the bodywork instead...

This is the whole debate, I personally feel that its fatigue and the more miles the car has done the more likely it is to break at the ringlands if you try and add performance. Lets face it these days its very hard to find a decent coupe with low miles that hasn’t been modded/ragged so time has already taken its tole on many of the engine by now.

The way you describe your driving style and power level it should be ok but who knows. Also what’s the point in having all that power if you don't go and push it every now and then because you’re worried about breaking it? I'm not trying to scare people and say changed to forged but the fact is there is no definite answer as to when/if you will break. If it does go pop you either give up on it or rebuilt it going forged.



If it does then mapping would only squeese a bit more power out and a waste of £500 IMO. Mapping is only need if a chip dosen't fuel/spark correct or you want to squeeze every last drop out of your engine.

I'm not worried about breaking it, and that's not the reason I dont push it very often.

When I do briefly give it the full beans every now and then it's really something

"I don't explore above 5000rpm" ha ha

Caught ya , I knew you couldn’t have a 300BHP car without giving it some . And so you should that's what it's there for, enjoyment

Just out of intrest if it does go pop will you give up or re-build?

Since when did rarely mean never?


If it goes pop then it stays in my garage until I decide what to do with it.

I would then have to decide whether to remove and sell all the tuning and aftermarket goodies, which would then fund returning it to standard including an engine rebuild or replacement, or sell it like that with a broken engine, everything else intact, or sit on it and save up for a while / get a better paid job (then forged)

That's the sprit

You want to be very careful runing 340lb/ft on standard rods

Nigel bent a rod runing 330lb/ft

My friend (wilkuw from fccuk forum) has 373Hp and 335lb/ft with std internals, and his car running without any problems too.. ..but I will think about forged rods and pistons.
