Firstly I would like to apologize for my "fluent" english, but I will do my best using the dictionary by my side.
I have Peugeot 605 2.0 8v turbo, 142P, 1994 model .... extremely dispirited power. That’s why I aim at 300HP @ crank at 1.2-1.3 boost.
So I started modifying my engine. I use my block from XU10J2TE with oil spraying nozzles for piston heat transfer in conjunction with 16v head from XU10J4 – 155 HP.
The head will be ported and polished, the volume of the combustion chamber will grow from 38cc up to 48cc, valve angles will be machined in order to improve flame propagation and to reduce the probability of detonations to the possible minimum
I bought brand new turbocharger Garrett GT2860RS. Very fast spinning turbocharger that produces maximum boost at low engine revs. Up to 1.5 bar boost and up to 35lb/h airflow.
New hand-made 4-2-1 exhaust manifold is being manufactured as well as divorced dual chamber downpipe for better response and performance. A couple of days ago I found by chance an intake manifold from GTi6 with 250mm equal length runners with a plenum. The double throttle plate was pretty small so I will fit the 63mm single one from my XU10J2TE. New vertical flow 18.5”x6”x3.50” FMIC from Mustang is on the way as well as 2.5” inlet piping, hoses, bends and clips. A HKS SSQV Blow-off valve will be in my hands on Friday or in worst case on Monday.
The major problem appeared to be the pistons. My engine uses 152mm conrods w. 22mm pressed wrist pin. In order to keep squish clearance within 1.0 – 1.1mm, I will need pistons with compression height 39.1mm …. There is no manufacturer that has in stock such pistons for S16 turbo conversion. So I have to order a set of 4 custom pistons. I hesitate between JE Pistons ($650 USD), Wiseco ($??? USD) and Woessner (900 EUR / $1170 USD). I have almost finished the drawing of the pistons’ dimensions and most probably JE will be my choice. All these 3 manufacturers are well known and have productions of good quality.
As regards to the ECU, I decided firmly to buy a set from Haltech, Australia that consists of E8 ECU, Wideband controller, Basic sensors pack (ATS, CTS, TPS), 3 bar absolute MAP sensor, Boost controller solenoid and Trim module.
If some feels that my project will be useful, I’ll share any information I have collected for the past half an year.
