Seing how nobody is bothering with my other thread I thought I would start a new one
My 1995 WRX has a IHI turbo on it, rollerbearing type, is it front entry or side entry ? I need to know because i might need a new one and im thinking TDO5 there is a front entry one on a well known auction site, what im asking is qwould mine have had to be converted to run this turbo ?
Thanks
p.s I want 350 hp

If you car is a MY95 WRX, then it will have 90 degree TD05 already fitted. The front entry IHI'd cars were made from 97 onwards.

Thanks for the reply, what im saying is I have an IHI TURBO on my car already Dont know what one though it was already on the car, now's the dilema does this mean it's been converted to run a front entry or has the turbo been altered If I want an upgrade then I will need to figure it somehow the only no's I could see were IhI Turbo RHF5

Hi James

I have seen a few IHI turbos converted to fit the early 93-96 90degree inlet configuration.
The best option for you I would have thought would be the TD05 from the same year of car (saloon) as it is a direct bolt on. It will struggle however to achieve your target of 350bhp.
Upgrades are available on the base (16G) version ie big 16G, 18G and 20G, if thats not enough then there is a '49' and '53' available too.
Beware of some of the international ebay and dodgy UK vendors turbos on the market just now, they are being sold as MHI units but are in fact just cheap far east manufactured replicas

Thanks Andy,
My only concern is the cost of a new ECU as well as Turbo and FMIC, not sure it would be worthwhile spending £750 for Turbo then another £750 for ECU with remap to gain 30-40Hp might as well go the whole hog and go for 400 Hp but then it's new injectors as well !would make more sense though £2000 for an extra 100Hp Im going to have a look at the turbo at the weekend and see what one it is, im only running 1.1-1.2 bar, if i wound the boost up on this turbo what do you do to combat knocking ?

If you wind the boost up then you will probably need to adjust fueling, ignition advance and acceleration enrichment. You can do this cheaper (if somewhat crudely) with an Apexi S-AFC and an adjustable fuel pressure reg but you would still really need someone who knows what they are doing to set it up and check it for you.
FWIW I wouldn't advise running over 1.2 bar on the std slanty intercooler.

Thanks Andy, the car has an uprated fuel pump and adjustable FPR the intercooler is from a newage wrx i think, will the intercooler be the limiting factor in this setup ?
Would fitting a FMIC reduce the detonation ?
Thanks again
