87 300SDL
87 300SDL
I've been around for a few years but usually lurking in the shadows. Anyway, I am starting to do "things" to my 87 300SDL. It currently has 163k and overall is in very good shape.
So far all I have done is swap in a 55 trim T3 from a 91 SDL. I like it, it seems much better than the KKK I took out. I also have a boost controller, set for stock 13.5 psi for now. Oh, and 314 nozzles and the OFV by Greazzer.
I got my hands on a w140 manifold and had a fiasco trying to get that mounted with a 55 trim T3 from the same car. Basically, the turbo was blocked by the spring housing by about 1 inch. Swears were said.
Thinking about it more, how did the 87 euro SDLs fit then????
Anyway, not willing to give up on that manifold, I have just bought an HX30 from Alcaid and am hoping that will fit. If not, I am going to make a flange that goes up about 70 degrees or so to clear the spring housing. Or there is always the crappy stock manifold...
I don't want to mess with the transmission so my goals are basically limited to 90cc of fuel or so. For now, I am just going to turn up the stock pump. I have an intercooler that I may throw in there too, even though I probably won't need it with the hx30.
I've been wondering though, with the HX30 being way more efficient than the t3, would I be able to break the supposed 175-180 hp limit of the 5.5 elements? GSXR dyno'd his stock turned up w124 and got 170-175 crank hp, and that was with the KKK and stock manifold. I think it should be possible to pull off maybe 185. The HX30 has to be about 4% more efficient at those levels. We will have to see....I don't suppose any of you out there put a holset on your 603 before modding the pump, have you?
I may look into a pump next year, but I have tons of house stuff to spend money on. At least I will have the parts needed to run one if I do decide to go that route.
Other stuff planned is just new bushings, maybe a 19mm sway bar in the rear, and possibly painting the body panels to match the car.
