Im having a conversation via PM with Halfwit. I just though id get everyone else opinion.

Assume you have a 90 CRX SI, curb weight is about 2200lbs. Its stock, nothing done to it, you have a $5000 budget, what would it take to make it run mid 13s with whatever combo you want, and it must be RELIABLE.

All Motor sets must be from HMOTORSONLINE.COM with their pricing. So dont say you can buy a GSR swap for $1500.

Here were my Top 3 reccomendations since i have to factor in labor as well.

1) B16 Swap from Hmotorsonline.com $1499
Avid racing motor mount kit $230
shift linkage $75
labor $735
axles $100
$2800ish

2) GSR swap from Hmotorsonline.com $3100
Hasport Hydro mount kit $390
OBD0-OBD1 conversion harness $100
Labor $735
Shift Linkage $75
$4400ish

3) D15B VTEC engine 130hp $450
CRX SI tranny $150
Clutch Stage2 $300
MSPi Turbo Kit $3500 installed
OBD1 ECU an conversion harness $280
$4900ish
his best bet is the GSR swap, its the best platform to build on. the FASTEST would be the D15 turbo, however, its a SOHC, and its a stock motor, so ..... but the good thing is if you blow it up, you can find another SOHC for CHEAP ($100 or so). you blow a GSR or B16 up its ALOT MORE EXPENSIVE.

The B16 is the easiest an cost effective, however it wont run 13s, an they dont like boost at all. they have weak ringlands and pop consistently.

I think the best bet is the GSR swap, with a simple wet kit, however, he would have to get it tuned which is more $$.

If you have any other input please share
