Working On Gear Box With PAR For 2.3L and 2.4L VE Motors
I have been trying for damn near 9 months to have a gear set made and it is one bullshit then the next bullshit. Anyway the guy from PAR got intouch with me this morning again so I hope we are going to get somewhere.
Please take note of a few things. A 200-210 WHP SR20VE will roast tires from 2000 RPMS up to red line with easy and chirp the tires very hard and even spin them a bit depending on tire when going to 2nd gear.
I am trying to get something built more for the street.
Stock SR20DE 125 WHP
When looking at the longer 1st gear please take note that a properly done
2L VE will be making an average of 210-225 WHP or 69% - 80% more power than a factory DE.
2.3L VE will be making an avergae of 250-270 WHP or 100% - 115% more power than a factory DE.
SR20DE motor average ( factory )
86mm x 86mm 125 WHP @ 6400 RPMs and 115 LB Ft Torque to the wheels
SR20DE Gear Box, FD 4.176 on 23 tires at 8000 RPMs
1. 3.063----12.791 = 43 MPH
2. 1.826-----7.625 = 72 MPH ----- 4769
3. 1.286-----5.370 = 102 MPH ---- 5634
4. 0.975-----4.072 = 134 MPH ---- 6065
5. 0.756-----3.157 = 173 MPH ---- 6203
SR23VE motor average
92mm x 86mm 260-270 WHP at 8500 - 9000 RPMs 190 LB Ft Torque
FD 4.7 FD with 23 tires at 8000 - 8500 - 9000 RPMs ( great for the 2.3L guys making power at 9000 RPMs ) 92mm bore x 86 mm stroke = 2.285L
1. 2.20 = 53 MPH -- 56 MPH -- 59 MPH
2. 1.65 = 71 MPH -- 75 MPH -- 79 MPH
3. 1.32 = 88 MPH -- 93 MPH -- 99 MPH
4. 1.10 = 106 MPH -- 114 MPH -- 119 MPH
5. My choice
SR24VE Motor average 260-270 WHP at 8000 RPMs and 205 LB Ft Torque at 8000 RPMs
FD 4.176 with 23" tires at 8000 RPMs ( Great for the 2.4L guys making power at 8000 RPMs ) 92mm bore x 92mm stroke = 2.45L
1. 2.20 = 59 MPH
2. 1.65 = 79 MPH
3. 1.32 = 99 MPH
4. 1.10 = 119 MPH
5. My choice
This is the SER box with the samd 4.176 FD matched to the PAR gears with 4.176 FD.
FD 4.176 on 23 tires at 8000 RPMs
1. 3.063 = 44 MPH ----- PAR 59 MPH
2. 1.826 = 72 MPH ----- PAR 79 MPH
3. 1.286 = 98 MPH ----- PAR 99 MPH
4. 0.975 = 131 MPH ---- PAR 119 MPH
5. 0.756 = 174 MPH
Or
PAR with 4.4 FD 23 tires at 8000 or 8500 RPMs
1. 2.20 = 57 MPH ---- 60 MPH
2. 1.65 = 74 MPH ---- 80 MPH
3. 1.32 = 94 MPH ---- 100 MPH
4. 1.10 = 113 MPH --- 120 MPH
5. My choice
Another set of gear box ratios I was looking at and the guy at PAR like also.
4.167 FD on 23in tires at 8000 - 8500 - 9000 RPMs
1. 2.40 = 55 MPH ---- 58 MPH ----- 61 MPH
2. 1.93 = 68 MPH ---- 72 MPH ----- 78 MPH
3. 1.53 = 86 MPH ---- 91 MPH ----- 96 MPH
4. 1.20 = 109 MPH --- 116 MPH --- 123 MPH
4.44 FD 8000 - 8500 - 9000 RPMs
1. 2.40 = 52 MPH ----- 55 MPH ---- 58 MPH
2. 1.93 = 64 MPH ----- 69 MPH ---- 73 MPH
3. 1.53 = 81 MPH ----- 86 MPH ---- 92 MPH
4. 1.20 = 104 MPH --- 110 MPH --- 117 MPH
The gear box above might be best used for track use and might be the best combo for street to. Depending on FD it still has a 9 to 11 MPH longer 1st gear,
These thing can be manipulate more with tires either going to 22s or 23.5.
Would like to hear from CORY, DERM, Jamie Marsh AKA ( SR20GTIR ), Rocco Ciccone AKA ( Mr.sentra_specv ).
