Fuel pump and boost levels R31-RB20DET

[wira4]

Pulse,
The Bosch "910" should not be classesd the same as 984/975. The 910 only gives flow rating of about 188lph compared to a 984 that does 220lph at the same pressure. The price of 910 is probably half as much as the 984.

I believe the 044 belongs to the in tank category but just about the same as 984 which is a external in line pump.

A lot of people say a pump flows this , and another flows this much , without actually seeing with their own eyes what they do . BOSCH have different part numbers to suit different applications in domestic as well as overseas markets , beleive me I have trialed them all on a flow bench and they all are within 3-5% of each other . 044 are motorsports EXTERNAL pumps with screw fittings on each end , and they are genuine because our fj20 powered drag car has them fitted and is making 900+ hp at 70psi rail pressure and the fuel system is getting close if not on its limit with 4 rochester 989 injectors .

thing is, my pumps the stock r31 RB30E unit. will this be able to handle fuel requirments of a VG30DET turbo and 13psi?

also can i fasion up a custom plenum without having to modify the comp? ie reattach everything except overboost valve and have forward facing throttlebody? i really hate the idea of the intake air going over the turbo/exhaust after getting cooled by the intercooler....
ive got family in the fabrication business so the construction wont be a problem. should i upgrade the throttle body while im at it?
budget is 1500 for turbo and intake plus some if i need to get a new fuel pump.
intercooler i can get made for 400, so 1100 for plenum materials and turbo.
should i go VG30DET or T3/T4 combo

what you think?

a custom plenum wont effect the factory computer
i have seen a few rb20's with VG30 turbos running on th stock pump successfully.
Id go the T3/T4 combo, as it doesnt have the ceramic exhaust wheel like the VG30 does
This will allow you to run higher boost safely

[kwazza11]

where would you suggest to go for a t3/4 turbo? who in adelaide could i talk to about the t3/4 and what is actually done to make the hybrid? is the t4 compressor housing attached and the wheels changed?

[fast31]

A T3/T4 hybrid is usually a T3 exhaust housing with a T4 compressor cover
There are many different exhaust and compressor wheels that can be profiled into the housings.
