What's the latest on you from your original post.....been running for over a year now with IHI power....any reliability issues??
Hopefully not that I've now taken the plunge with the
help of Bill and some ex TSR. I'm pegging mine back somewhat unless I uprate the rods and valves which I'm thinking is probably a good idea for track.
Will probably go for a engine check over as it's now 100k but it has been pretty much faultless apart from MAF. Been running APR stage 2 and FMIC Milltek etc since new almost...nice package but now bored.
Only thing I'm worried about is melting turbo housings...how much are these on P18/20 housings?Low boost 1.2-1.4 max should
help.
Baffled sump catch tank to be fitted too.
I have no doubts whatsoever about the reliability of the IHI for normal road use - I have no regrets at all and I would do exactly the same again
I felt much like youself when I was considering the prospect of getting work done on my car - all I ever read was stories of disasters - so i can well understand you concerns
I have had problems but I put them down to my own lack of experience and my own foolish forgetfulness regarding the maxim - `if it ain`t broke don`t try to fix it`
Prior to GTI Inters and purely,and for cosmetic reasons alone, I decided to change the DV - the car had been going so well for 17k miles I guess i was getting bored and looking for something to do!
The valve I was supplied with was faulty - that is the kindest description I can offer in the public domain - and in a period of 10 days from fitting, it caused the turbo bearings to fail[ as a consequence of the valve`s inability to do any `diverting`] and I was landed with a £1000 bill for a new unit - I was not a happy bunny
The big caveat here is to very careful with what you fit - all that glitters is not gold or silver or polished alloy or what have you! - because it looks nice doesn`t mean it works any better - Top tuners like APR even retain the standard Bosch DV and VAG airbox in their BT applications
I am well over that now having done over 17k with the new unit without any probs
I am still using the original turbo exhaust housing, manifold and downpipe at 34k IHI miles without any problems - the highest EGT i`ve see is 870 deg downstream of the turbo - and that was after a good thrashing, and i`m talking here about really
ffaasstt - if the car is correctly engineered and set up by a competent professional, then in road use, you`re more likely to end up in jail before you do an exhaust housing.
Hope this helps - I am hoping to do a more comprehensive overview of my years IHI motoring with outline costs etc when I have more time to post over the holiday period
