jdm hawkeye sti engines
 

hi,trying to gather some more info on the jdm hawkeye sti,i need info on engine/turbo etc. what turbo is fitted as standard and its capabilities? closed/open/semi closed block??? dont really know much about the specs so any info regarding engine,turbo,gearbox etc etc,standard output figure and also do they start on 2005?:confused: thanks.

To start with they are a 2.0lt lump with high quality pistons as standard, plus they are fitted with a twin scroll turbo setup allowing a much earlier spool up. Imo these engines are by far the best to thrash as they love to rev and are much stronger than the uk version;) Are you looking to buy a jdm hawkeye then? If so then i can help you out there as my close friend is just about to sell his 56 plate Jdm hawkeye with the full type20 kit:)

semi closed deck I believe, VF37 turbo. 350bhp is normal with air filter, exhaust and remap. rev limit at 8k revs. gearing is lower than UK car but I find mine acceptable. Think the diffs are different to UK cars as well. Loads of info on net though, just google uk vs jdm and loads of different forums and posts asking the same.

yep defo going for a jdm hawk sti but not for a good few months:(

yeah i realise that mate,but i wanted it to come from the horse mouth so to speak,(actual jdm hawkeye sti owners):thumb:

done quite a bit of google research but unable to find all the answers.

what else do you need to know?

standard power/torque output?

Latest hatchbacks are 308ps, think the hawkeyes are 300ps approx with 308lbs of torque, now in the real world its more like 315bhp and 330lbs of torque ;) but the output is higher than that of a similar aged UK 2.5.
As for gearing, well yes its lower than a UK car (5th and 6th only) but it revs higher ;) so at 70mph in 6th your doing 3000rpm, not really straining the car is it? ;)

Tony:D

for some unknown reason mine does an extra couple of mpg than my uk car. Probably due to increased low down torque.

Out the box, made 320bhp and 300lbs

just remapped for UK fuel mine made 327bhp and 315lbs

Mine was then converted to a T20 with and exhaust remapped to 351/350

IIRC

it is now with a LM400 turbo 405bhp :D

Tony

it sounds awesome,i must get me one.hopefully before xmas.is there anything in particular i should look out for?(as in....to make sure im getting a proper jdm sti hawk?)anything i should avoid?

a UK Hawk ;) IMHO


Tony

very nice:luxhello:

What other mods do you need other than the LM400 to get 405bhp what about injectors and the like ???

you need decatted/Sports cat system, uprated fuel pump, remap :D and thats it :luxhello: using std induction395bhp

:lol1: It's not that bad is it Tony? If you keep it relatively standard....

TBH, i actually find the low-mid range pulling power of the UK car abit better than my JDM. But having said that, i still will not trade my JDM for a UK car. :D

The LM400 is capable of running over 400bhp on the OE TMIC and OE Inlet, on a Newage JDM 2ltr.

Mine made 398bhp on the rollers with this spec (plus decat, injectors and 3port boost solenoid) but was slightly down on airflow due to environment conditions. Cooler air would of seen it over 400bhp.

For an LM400 it is questionable whether you need to change the OE injectors and OE 2 port boost solenoid. Probably not worth the extra expense for the (in theory) small gains.

Shaun I was under the impression the OE injectors are maxed out at 360bhp (stage 1 figures)?

If they have 550cc injectors like uk Sti what's the most bhp they can run ???
