Looking at a forged 450/500bhp Scooby in the next couple of months and heard mixed things on the hawk 2.5 lump???
Although I have seen a nice one for sale at the mo with 450bhp (forged)

Otherwise ive heard the 2.1 stroker on a blob forged rebuild is the one to go for?

Any words of wisdom before I go out and spend my hard earned?

Thanks

Buy a non forged jdm widetrack in a blob or Hawkeye instead and do it up yourself

2.5 closed deck will be fine at 450/500 and give alot more low down grunt than a 2.0 or a 2.1. It doesnt rev as high though so really depends on what you want.

For a road car 450bhp 2.5 with a uk 6 speed is an epic combo

What about the fact its a semi closed deck 2.5 hawk??

Still good for a reliable 450bhp??

Many thanks so for guys.

You sure it’s a H and Not a T

Yep, apparently it is one of the first/original versions, 76mm I think

My H made 441hp, the T I have now made 466hp, that was running 20%meth and same set up for both, forged 2.5/wrx heads.

How many miles have you done on that level of tune and power?

Thanks,

My 2.5 with a T made 459/506 on meth, but I killed it on track

The engine was completely rebuilt following HG failure in 2013 but it's a sleeved/pinned block which is good for 500hp but no more.
A normal forged 2.5 with the right build might be ok at 450hp but once you start track use/quarter mile it's got to be a when not if.

Road and track/drag builds are a very very different kettle of fish.

That must be epic on the road... Ludicrously responsive?

majority do mainly road and some track/drag which is where the problems come.

aye, i know some folks who get a road engine, use it for race/drag then blame the builder when it blows up.

When I blew mine up I knew it was my thought, going for 5th at high revs and hitting 3rd didn’t help

Just built a 2.35 instead

It certainly makes me
Originally I was thinking 2.1, but then this came up and I really enjoy it
